Low carbon life is a very environmental protection and civilization. my understanding is that of low carbon in daily life from yourself, from small start, minimize every possible cost. of course, low carbon is main or refers to reduce carbon dioxide emissions.
Actually, low carbon life from everyone very close, as long as pay more attention to some of the details, life can have to reduce energy consumption role. my life in some low carbon small doohickey of water-saving aspects is aims at. production tap water and wastewater treatment are to a significant amount of energy. so, water is energy saving.
For example; water may be used for washing a face wash the feet of water, wash clothes can be used to rinse dishcloth, clean the floor, then these wastewater can again to flush the toilet; water after washing vegetable can be used to water the flowers. dont look down upon these water reuse, accumulated, only a 3 home can save a ton per month above water.
In addition, if monthly wash clothes, so once per washer can save electricity, also saves power of the coal, also will reduce carbon emissions, if all the family can do monthly by hand to wash clothes, reduce the emissions of carbon dioxide once is 68.4 tons, can achieve this figure is very surprising. meanwhile, but use washing machine while holding with clothes to wash washing machine also can cause unnecessary waste.
So for us students have more ways energy-saving
Paper, save paper; use double-sided
Need not disposable chopsticks and disposable lunch box;
Need not disposable bags;
Reduce food waste;
The lights on, conveniently mind faucet.
Our earth needs we work together to love, let us start from around things, cherish resources, reduce the energy consumption and make our life more beautiful.
I was one of the only kids in college who had a reason to go to the P.O. box at the end of the day, and that was mainly because my mother has never believed in email, in Facebook, in texting or cell phones in general. And so while other kids were BBM-ing their parents, I was literally waiting by the mailbox to get a letter from home to see how the weekend had gone, which was a little frustrating when Grandma was in the hospital, but I was just looking for some sort of scribble, some unkempt cursive from my mother.
And so when I moved to New York City after college and got completely sucker-punched in the face by depression, I did the only thing I could think of at the time. I wrote those same kinds of letters that my mother had written me for strangers, and tucked them all throughout the city, dozens and dozens of them. I left them everywhere, in cafes and in libraries, at the U.N., everywhere. I blogged about those letters and the days when they were necessary, and I posed a kind of crazy promise to the Internet: that if you asked me for a hand-written letter, I would write you one, no questions asked. Overnight, my inbox morphed into this harbor of heartbreak -- a single mother in Sacramento, a girl being bullied in rural Kansas, all asking me, a 22-year-old girl who barely even knew her own coffee order, to write them a love letter and give them a reason to wait by the mailbox.
Well, today I fuel a global organization that is fueled by those trips to the mailbox, fueled by the ways in which we can harness social media like never before to write and mail strangers letters when they need them most, but most of all, fueled by crates of mail like this one, my trusty mail crate, filled with the scriptings of ordinary people, strangers writing letters to other strangers not because they're ever going to meet and laugh over a cup of coffee, but because they have found one another by way of letter-writing.
But, you know, the thing that always gets me about these letters is that most of them have been written by people that have never known themselves loved on a piece of paper. They could not tell you about the ink of their own love letters. They're the ones from my generation, the ones of us that have grown up into a world where everything is paperless, and where some of our best conversations have happened upon a screen. We have learned to diary our pain onto Facebook, and we speak swiftly in 140 characters or less.
But what if it's not about efficiency this time? I was on the subway yesterday with this mail crate, which is a conversation starter, let me tell you. If you ever need one, just carry one of these. (Laughter) And a man just stared at me, and he was like, "Well, why don't you use the Internet?" And I thought, "Well, sir, I am not a strategist, nor am I specialist. I am merely a storyteller." And so I could tell you about a woman whose husband has just come home from Afghanistan, and she is having a hard time unearthing this thing called conversation, and so she tucks love letters throughout the house as a way to say, "Come back to me. Find me when you can." Or a girl who decides that she is going to leave love letters around her campus in Dubuque, Iowa, only to find her efforts ripple-effected the next day when she walks out onto the quad and finds love letters hanging from the trees, tucked in the bushes and the benches. Or the man who decides that he is going to take his life, uses Facebook as a way to say goodbye to friends and family. Well, tonight he sleeps safely with a stack of letters just like this one tucked beneath his pillow, scripted by strangers who were there for him when.
These are the kinds of stories that convinced me that letter-writing will never again need to flip back her hair and talk about efficiency, because she is an art form now, all the parts of her, the signing, the scripting, the mailing, the doodles in the margins. The mere fact that somebody would even just sit down, pull out a piece of paper and think about someone the whole way through, with an intention that is so much harder to unearth when the browser is up and the iPhone is pinging and we've got six conversations rolling in at once, that is an art form that does not fall down to the Goliath of "get faster," no matter how many social networks we might join. We still clutch close these letters to our chest, to the words that speak louder than loud, when we turn pages into palettes to say the things that we have needed to say, the words that we have needed to write, to sisters and brothers and even to strangers, for far too long. Thank you. (Applause) (Applause)
Dear teachers and students
hello everyone!
In order to ensure the safety and stability of the school, prevent various accidents and create a good safety environment for the construction of a "safe campus", I used today's speech time under the national flag to carry out winter safety education for all the students of the school, and talked with the students on how to prevent fire safety in winter. It is hoped that students will not only popularize safety knowledge, but also enhance safety awareness through such safety education activities.
1. Fire is a friend of mankind. It brings light and warmth to people, human civilization and social progress. However, if the fire is out of control and becomes a fire, it will cause huge losses to people's lives and property. Students should fully understand the harm and possible serious consequences of playing with fire, and resolutely refrain from playing with fire at any time. Students should urge and remind each other.
2. Students should take good care of the fire-fighting facilities in the teaching building and dormitory building, and protect all kinds of electrical switches, power lines, fire hydrants and fire extinguishers in the campus.
3. Be especially careful with fire. Do not place inflammables and explosives near the fire source. In case of air leakage, quickly close the valve and open the window at the same time. Do not touch electrical switches or use open flames to avoid explosion. 4. In daily life, in case of fire, you should dial "119" to call the police quickly. When smoke comes out, you should cover your mouth with wet clothes and escape near the ground. Never be greedy for money, because life comes first.
5. Pay attention to the 'circulation' of indoor air in winter, especially when heating and bathing, open windows for ventilation to prevent gas and carbon monoxide poisoning. The lessons of history are heavy.
Safety first is the most fundamental guarantee of family happiness. Improve your ability to prevent and protect yourself anytime, anywhere, and connect you and me safely! Let's work together to make our life shine, share safe sunshine, enjoy safe happiness, and work together to create a harmonious, healthy and lively campus atmosphere!
Thank you!
Dream is the winter fire, it is autumn, spring summer, as long as have a dream, the spring of life will shine bright fireworks.
"Yao is not snow, for a fragrance" is the dream of cold winter plum blossom. In gale of laying, bullying in the cold snow, she still stand proudly, conceits in a piece of white pink, send out faint fragrance, when all the flowers are bent down, only the plum blossom her fearless in oppression. Because she knew "plum blossom incense from" you can't afford to bank everything, that stands in the snow of the plum blossom, is more noble. Is a dream, let the cold winter plum blossom ling2 han2 open alone.
"No is not heartless, maternal gentleness is more protect flower" is the dream of bleak autumn maple leaves. Autumn wind faded the luster of the maple leaf, rain washed the maple leaf green, when he is faced with the loss of life, he was as cool as a cucumber, he enjoy the autumn wind dance brought him comfort, enjoy the autumn rain washing on earth, he think that it is the gift of god to him, that is before his mission to encourage, to his brave, let him bring autumn poetry. Happy is a dream, let the bleak autumn maple leaves are cool.
"Infinite blue day lotus plants, video on lotus another red" is the dream of hot summer lotus root, in mud messy, she weeds were wrapped tightly, vulnerability, such as her, how will you move that exists, she can only silently waiting for, any time a little bit of patience to kill weeds, finally the day came, she rushed out of the weeds, grow from the silt, bloom their brilliant, she is more beautiful, zhou yuan and said she "the silt but not imbrued, zhuo QingLian without demon", a hot summer day, the strong sun baked the pedestrian, only her graceful net plant, to cold summer is smooth. Is a dream, let the heat of summer lotus XiangYuan yi qing.
The beauty of the dream we cannot grasp, dream of the great we will be able to guess. As long as have a dream life will bloom.
梦想是冬日的篝火，是秋日的外衣，是夏日的泉水，只要有梦想，人生的春天就会绽放璀璨的焰火。
“遥知不是雪，为有暗香来”是寒冷冬日梅花的梦想。在烈风的.抽打下，在寒雪的欺凌下，她依然傲然挺立，在一片雪白中绽出一点粉嫩，散发淡淡的幽香，当所有的花朵都弯下腰的时候，只有梅花她无畏于压迫。因为她知道“梅花香自苦寒来”，那在雪中屹立的梅花，是多高贵啊。是梦想，让寒冷冬日的梅花“凌寒独自开”。
“落红不是无情物，化作春泥更护花”是萧瑟秋日枫叶的梦想。秋风褪去了枫叶的光泽，秋雨洗刷了枫叶的嫩绿，当他面对即将逝去的生命的时候，他镇定自若，他享受秋风带他翩翩起舞的舒适，享受秋雨洗涤身上泥土的惬意，他认为那是上天带给他的礼物，那是在他完成使命前的鼓励，让他勇敢面对，让他给秋天带来诗意。是梦想，让萧瑟秋天的枫叶淡然快乐。
“接天莲叶无穷碧，映日荷花别样红”是酷热夏日莲藕的梦想，在杂乱的淤泥中，她被杂草紧紧包裹，柔弱如她，怎能动弹分毫，她只能静静的等待，任时光一点点消磨杂草的耐心，终于那一天还是来了，她冲出杂草的包围，从淤泥中生长出来，绽放自己的灿烂，她是多美丽，周元公说她“出淤泥而不染，濯清涟而不妖”，炎热的夏日，浓烈的阳光烘烤着行人，只有她亭亭净植，给夏日平添透心凉。是梦想，让酷热夏日的荷花香远益清。
梦想的美丽我们无法捉摸，梦想的伟大我们无法猜测。只要有梦想人生就会春暖花开。
In today's fast-paced world and with the booming economy, stress is our constant companion. We may face stress from our jobs, families, peers, etc. Though stress adds flavor and challenge to life, too much stress can seriously affect people's physical and mental well-being, so it is necessary to handle stress properly.
When it comes to reducing stress, people vary in their ways. Some people talk with someone, perhaps a friend or a family member, about their anxieties and worries. Others allow themselves a mental “get-away”: a quiet country scene painted mentally can pert them from the tension of a stressful situation to a more relaxing frame of mind. There are also people who create a sense of peace by reading a good book.
The effective way to relieve stress for me is different from those mentioned above. I have several relaxation techniques. For examples, when stress occurs, I would take a deep breath and exhale and if possible, I would take a warm bath. They prove to be very helpful. They help me to calm down my mind and improve my response.
Dear teachers, dear students:
hello everyone!
The topic of my speech is "the hardness of life"
The vast desert, a tree stand, the show is a monument to the image.
Towering mountains, thousands of tree stand up, as is a magnificent the Great Wall.
The long river, all the trees stood up into a dragon of glory.
We are a symbol of too much, and too much. But I believe that my image is not "the gentlest hands, skin, such as Diorskin" Lin Daiyu, nor is the modern "unkempt and shabby", "Su Qier". We are a symbol of hope and vitality. So we show in front of others should be inserted without pleats, face without scale, modest and polite gestures exudes a stream of heroic spirit, the image of the vigor and vitality of the modern new youth, a into the embodiment of the spirit of nature.
Someone once said, life is a kind of hardness, integrity and dignity of life is propped up the hardness of bone. "Better life" and "the Kui back in the day, and not ashamed on the ground", which is always the traditional virtue of the China. Li Bai's "the eyebrow nengcui Zheyaoshan powerful thing, so that I may not be happy Yan" this awe inspiring atmosphere of the verse and whether it will make those no self-esteem people to shame? Loss of self-esteem is a worthless person, and we as the vanguard of the times, if drown in the darkness forever, or to do a dauntless hero, a flower in the wind and rain sonorous rose. The answer is self-evident.
Desert desolate also has the monument stands, Castle Peak again proud, but also have the great wall around, the river again quiet, also there is a dragon in the recumbent. But the time can be changed, our image, our glory remains the same. Because we pride, because we are confident, because we have a fresh life. And because of this, it is a vast desert riparian long, Qingshan was evergreen, the hardness of life is forever.
尊敬的各位老师，亲爱的同学们：
大家好!
我演讲的题目是《生命的硬度》
茫茫大漠，一棵树站不起来，展现出来的是一座丰碑的形象。
巍巍青山，千万棵树站起来，连成的是一条长城的宏伟。
悠悠河岸，所有的树站起来，缀成的是一条蛟龙的雄风。
我们象征着太多，又演绎着太多。但我相信，我的形象，绝不是“手若柔荑，肤如凝脂”的林黛玉，也绝不是“蓬头垢面、衣衫褴褛”的现代“苏乞儿”。我们象征着希望、朝气。所以我们展现在别人面前的就应该是衣无褶、脸无垢、礼貌谦和的举手投足间散发着一股英气，朝气和活力的现代新青年的形象，一个融入了大自然的精灵的化身。
有人曾说，生命有一种硬度，气节和尊严是撑起生命硬度的骨骼。“宁为玉碎，不为瓦全”、“仰不愧于天，俯不怍于地”，这是历来中国的传统美德。李白的“安能摧眉折腰事权贵，使我不得开心颜”这一大气凛然的诗句又是否会让那些毫无自尊的人汗颜?丧失了自尊的人是一个没出息的人，而我们作为时代的先锋，要是永远在黑暗中沉溺呢，还是要做一个顶天立地的好男儿，一朵绽放在风雨中的铿锵玫瑰。答案，不言而喻。
大漠再荒凉也有丰碑的矗立，青山再孤高，也有长城的环绕，河水再平静，也有蛟龙的横卧。而时代再怎么变，我们的形象，我们的雄风依然如故。因为我们自尊，因为我们自信，因为我们有着鲜活的生命。而正因如此，河岸才悠悠，大漠才广袤，青山才长青，生命的硬度才长存。
Life on earth are the most valuable things money can not buy、jewelry—for—not go back. Life only once、should not renewable and will not re—COME. Students、and your life has just begun blooming flower、you are prosperous home sustenance、development of the Chinese nation are the hope of；your future offspring transmission of both task and maintenance obligations of parents. Therefore、you have to cherish life and take care of life、for themselves and for parents、good for homeland alive.
Life for each person only once、no life、everything is no—go. Therefore、we must firmly embrace the "Yes to life、safety first" awareness of construction safety of our campus so that students can grow up healthily.
Campus safety relates to our lives and learning potential safety problems have as many as 20 kinds、including traffic accidents、poisoning、fire fire、drowning、sports injury and so on. These are at times a threat to the healthy growth of young students. According to statistics、every year our country has around 16、000 unnatural deaths in the primary、elementary and middle school students because of safety accidents、food poisoning、drowning and other deaths、the average has more than 40 people every day、that is to say every day there will be a class of students at "disappeared." So we not only have safety awareness、and more importantly、prevention awareness and preventive measures. Study at daily life、we should note the following：
One、pay attention to safety recess activity. Want the students up and down stairs in an orderly manner and must not hurriedly up and down、up and down the stairs right to cultivate the good habit of walking to prevent accidents on campus crowded stampede. Rainy at our school buildings and office building corridor、staircase、will be very slippery、please the whole Student must light when walking at the foot walk. Everyone should pay attention to civilization recess breaks should not chased noisy.
it is necessary to pay attention to traffic safety. We must strictly comply with rules of the road、without people to ride、not red light running、horse way to go before crosswalks、it is necessary to take the initiative to avoid motor vehicles. Not want to develop the habit of school by bike.
pay attention to food safety. Not to buy "three noes" of food；we should not be at the school gate and street stalls mobile buy snacks、to prevent food poisoning. To learn how to protect themselves、take care of themselves、pay attention not to overeating、try eating less food cold.
it is necessary to pay attention to sports safety. On physical education and extra—curricular activities to prepare before the warming—up、attention should be paid to exercise when not to dramatic collision、so as not to be knocked down or fall.
it is necessary to pay attention to Internet security. Network is a very good learning tool、we can use it to gather information、broaden our horizon. But the network also has a lot of harm、if unhealthy Internet browsing web pages、or indulge in unrestrained virtual space、then it will affect our physical and mental health.
students for their own actions but also have safety awareness. Student encountered at the contradictions between、we want a calm、rational、should not substitute for reasoning with fists、give themselves and their classmates bring about adverse effects. Conflict with the people must bear in mind：the broader picture.
Teacher and fellow students、only one person's life. A collision、a wrestling are probably the lives of vulnerable people's hard to imagine the harm caused. Therefore want to protect their own safety、we comply with the minimum required、the most simple rules and order. Let us bear in mind：human life、safety first！Let us work together to create a harmonious campus、campus safety！
My name is , from . I scored unsatisfactory and did their desired universities. I think, either in the country on a first-clacolleges, or to go abroad. If on a domestic university, it is a waste of time. So I chose to study abroad.
So I understand that New Zealand students through the Internet has more advantages. First of all, New Zealand is a multicultural country, a time-advanced level. Second, the students lower costs than other countries, more reasonable. Third, the weather and almost southern China. Therefore, I propose to the parents to New Zealand to study the wishes of the parents get the support.
From 06 to 07, I CIBT School of Beijing University of Technology to study for two years, I am learning is that I am interested in businemanagement. Through this two-year study, as in the commercial, I later laid a foundation for learning.
Many schools in New Zealand, I chose the UNITEC Institute. UNITEC is unique in that the traditional university academic standards and polytechnics and technical advantages of combining vocational education. School in combining theory and practice for school concept, exploring the creativity of the students to continue to adapt to social change.
This year, China will host the Olympic Games in Beijing. , The eyes of the world gathered here. In particular, some businessmen in China, a huge potential market in search of busineopportunities. Therefore, I choose to UNITEC Institute study marketing, I believe that this right after I returned employment development will be of great help. UNITEC particularly to the integration of theory and practical teaching methods, more determined my choice. Reading through UNITEC of Chinese students in the exchange, I understand MARKETING study very hard, I need to put more time and energy on top. Maybe I can not be like the other students on edge as the Edge Reading. But my parents understood my idea, I am willing to fully support the school.
Water, sky, ground, sea, rivers and lakes are. For water conservation, the students always feel as section.
Save something else less important. Some students on the tap, foot, scouring, some students a drink of water, but the mouth facing the faucet to drink tap water, sound of rushing water, and does not feel bad. Water line really worth it? Water conservation is really unimportant? Not the world's water 93% is salt water, not drink. Accounted for only 7% of fresh water, and drink water only accounts for eight per cent of zero. Billion people around the world, we depend on it accounted for only 0.8% drinking fresh water, watching, water and more valuable ah! Although there are three liters of water per person per day will be able to maintain life, but in fact of urban residents per person per day cooking, washing, washing vegetables ... ... everything can not do without water, water up to several hundred liters. In addition, the farming and industrial production can not do without water. People can live several days without eating a few days without water can not. Can not afford to humanity is to survive away from water, showing how important it is to save water.
Water conservation "is not limited to water, but not let water. In fact, people save water is a reasonable use of water, efficient use of water. Save water does not affect our quality of life. Everyone has the value of resources wasted to correct others水obligations. The idea that "as long as I pay the water, you can whim, waste water is my own business, others out of mind" point of view is wrong, our country, "Water Law" that water resources belong to the state , that is, the whole people. provide for countries around the world, water is public property. Therefore, everyone should have public water awareness. power resources are very precious, unite the hard work of many people. Everyone should love the water, saving water against pollution of water and waste water. "calendar view forerunners state and family, as the thrift failure by the extravagance. "Qinjianchijia, diligence and universities, this is a morality, is a virtue.. Students, we are a small host country, from small water conservation should develop good thinking habits. Whether in school or in Outside the school, should pay attention to water conservation. We must take practical action to be a good boy to save water.

亲爱的老师，同学们：
我很高兴可以在这个课堂上做一次演讲。这一次，我想谈谈英语。我的话题是我爱英语。
正如每个人所知，英语在今天十分重要。它已经被应用到世界的各个角落。它已经成为商业上最为通用的一门语言并广泛的用于国际贸易。如果我们能说好英语，我们就有更多的机会成功。因为越来越多的人注意到这一点，学英语的人数正在已很高的速度增长。
但是对我而言，我学英语不仅仅因为它的重要性以及它的实用性，更是因为我喜爱英语。当我学英语时，我可以体会到一种不同的思维方式，它可以给我更多接触世界的空间。当我读英语小说时，我能感受到不同于阅读翻译文的快乐。当我说英语时，我可以感到自信。当我写英语时，我能够感到不同于汉语的那种美……
我爱英语，它给了我一个色彩斑斓的梦。我希望有朝一日我可以畅游世界，用我流利的英语，我可以和世界各地的人交友。我能看到许多的名胜。我希望我能够到伦敦去，因为那里是英语的故乡。
我也希望用我流利的英语来将我们的名胜介绍给说英语的朋友，我希望他们可以像我们一样的爱我们的国家。
我知道，罗马不是一天筑成的。(成功需要日积月累。)我相信在持续不断的努力学习下，总有一天我可以拥有一口流利的英语。
如果你想被爱，你就应该学着去爱他人。所以我相信我对英语的爱定将换来它对我的爱。
我相信总有一天我会实现我的梦!
谢谢!
Friendshi
友谊
Every one of us, rich or poor, should at least have one or two good friends. My friends will listen to me when I want to speak, will wipe my eyes when I cry, will take care of me when I am sick, and my friends will go together with me side by side through this journey of life.
我们每个人,不论富裕还是贫穷,至少应该有一个或两个好朋友。我的朋友会听我说,如果我想说话,要擦去我的眼睛当我哭泣,会照顾我在我生病时,我的朋友将与我一起肩并肩在这人生旅程。
Friendship is a kind of treasure in our lives. It is actually like a bottle of wine, the longer it is kept, the sweeter it will be. It is also like a cup of tea. When we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink.
友谊是一种财宝在我们的生活。它实际上是像一瓶酒,越久保留,这将是更香甜。它就像一杯茶。当我们口渴时,这将是对我们最好的选择,但当我们有足够的时间去玩得很开心的,它也是最芬芳的饮料。
All of us have to spare some time for personal lives. We have to find the chance to express our emotion and love. When staying with our friends, we can release ourselves completely. We can do whatever we want, we can laugh together, talk together, and even cry to-gether. I should say that being together with our best friends is the most wonderful moment of our lives.
我们所有的人都要花点时间来个人的生活。我们必须找到机会来表达我们的感情和爱。当住在我们的朋友,我们可以放松自己完全。我们可以做任何我们想要的,我们能一起大声笑,一起交谈,甚至哭泣下。我应该说,是我们最好的朋友一起是最精彩的时刻,我们的生活。
Knowledge is one thing, virtue is another; good sense is not conscience,refinement is not humility, nor is largeness and justness of view faith.Philosophy, however enlightened, however profound, gives no command over thepassions, no influential motives, no vivifying principles.
Liberal Education makes not the Christian, not the Catholic, but thegentleman. It is well to be a gentleman, it is well to have a cultivatedintellect, a delicate taste, a candid, equitable, dispassionate mind, a nobleand courteous bearing in the conduct of life--these are the connatural qualitiesof a large knowledge; they are the objects of a University; I am advocating, Ishall illustrate and insist upon them; but still, I repeat, they are noguarantee for sanctity or even for conscientiousness, they may attach to the manof the world, to the profligate, to the heartless, pleasant, alas, andattractive as he shows when decked out in them. Taken by themselves, they do butseem to be what they are not; they look like virtue at a distance, but they aredetected by close observers, and on the long run; and hence it is that they arepopularly accused of pretense and hypocrisy, not, I repeat, from their ownfault, but because their professors and their admirers persist in taking themfor what they are not, and are officious in arrogating for them a praise towhich they have no claim. Quarry the granite rock with razors, or moor thevessel with a thread of silk, then may you hope with such keen and delicateinstruments as human knowledge and human reason to contend against those giants,the passion and the pride of man.
People always say that father’s love is so quiet but grand that it seemslike a mountain. They always bury their love to children deep in the bottom oftheir hearts and never show it. Father seldom says I love you to their childrenor does something show it. Mother often tells us to eat more and put on moreclothes, but father doesn’t. Father seldom asks your life in school or yourrelationship with your friends. When you are in trouble and ask suggestions fromhim, he would not tell you what you should do but help you to find solutionsinstead. However, father still plays the most important role in your life. He isalways the supporter of your life. Whenever you need, he is always by your side.This is the way he shows his love.
The day before yesterday,someone gave me a phone call.he said“che ,i am your leader,come to my office room right now”so i felt anxious and said”who are you?and what did i do?”.he just said”i am just your leader”.i realized he is a cheater.so i said”i will call the police”he hung up immediately.so i felt scared.and i have a question:who leak my information? Ten years ago,i have never thought our personal information is important.but now if your phone number is leaked,you will be drowned in a sea of junk short message.the ID card number is one of your most important personal information.because your bank card, driving license, student card and personal resume are both binding to your ID card number.so if your ID card number leaked, that completely is a disaster. How did my information leak? In some film, a hacker use a computer attack a website and get many information.that is true.many computer virus can do this.and today is the age of big data, a good hacker can get your password from your other information.for example,a hacker build a false website, and you register for an account.the hacker would get your password and your email address. Sometimes the password is your bank account password.He just need to send you a e-mail with computer virus.your bank account and password will be leaked. So what should we do to protect our information security? First of all we shouldn’t tell others our personal information.most of the information leakage event is from our carelessness.besides,we shouldn’t register for an account easily.and i still hold a belief on don’t using number is the best way to protect information security
前天,有人给了我一个电话。他说:“切,我是你的领袖,现在到我的办公室来房间”所以我感到焦虑,说:“你是谁?和我做了什么呢?”。他只是说“我只是你的领袖”。我意识到他是一个骗子。所以我说“我会叫警察”他立即挂了电话。所以我觉得害怕。我有一个问题:谁泄露我的信息?十年前,我没想到我们的个人信息很重要。但是现在如果泄露你的电话号码,你就会(被)淹死的垃圾短信。身份证号码是你最重要的个人信息。因为你的银行卡,驾驶证、学生证和个人简历都绑定到您的身份证号码。如果你的身份证号码泄露,那完全是一场灾难。我的信息泄漏吗?在一些电影中,黑客用电脑攻击网站,获得许多信息。这是正确的。许多计算机病毒可以做到这一点。今天是大数据的时代,一个好的黑客从你的其他信息可以得到你的密码。例如,黑客建立一个虚假网站,你注册一个账户。黑客会得到你的密码和电子邮件地址。有时,密码是你的银行账户密码。他只需要送你一个电子邮件的计算机病毒。你的银行账户和密码泄露。那么我们应该做些什么来保护我们的信息安全?首先我们不应该告诉别人我们的个人信息。大部分的信息泄漏事件是我们的粗心大意。此外,我们不应该轻易注册一个帐户。我仍然持有的信念不使用号码是保护信息安全的最好办法。
heart.Real fris can share all our sorrows and double all ourjoys.While making fris, we should take care to select those who have suchfine qualities.
hen we should treat our fris with courtesy, be careful notto interfere unreasonably with them,and not to ridicule their proceedings.Weshould forgive their failures and do our best to help them.In short, when wehave established friship, we ought to cherish and treasure it by means ofwords and deeds.Only thus, can we develop real friship and keep the sacredlamp of friship burning all our life.
Newspapers in recent days, has been published reports of haze weather, there is a marked in today"s newspaper "recently air quality will not significantly improve" headline. Air quality is really bad, said on the radio in the school has the heavy pollution, demands that we don"t do sports on the playground, in the dirty air movement, feeling himself a vacuum cleaner.
These days the weather is getting warm, but that the fog still lingering. From the Windows overlooking the distant place, or a piece of confusion, near the corner of the sky seems to have some better, show a little bit of blue, but still with grey. Grandma and I go out for a walk, when people feel like quilt in a huge glass, breathing is very difficult and gas absorption into his mouth and a disgusting smell of powder.
The fog and haze, why? We do wrong? Is this the sky for our punishment?
nowadays more and more young people prefer to follow the fashion. the word 'fashion' is generally used to mean style in clothing. they make people handsome and cool. also, fashion can be something strange. from that we can be different from others. but all of these can change from time to time. and valuable personal qualities and characters never change. so i think they are the true fashions.
helpful and warm-hearted is a kind of fashion because not everyone can be like that. if you are not willing to help others, it is difficult for you to get along well with others. if you can always have a lot of friends, you are fashionable.
love is always important in the world. many people around the world need care and love. if you can show you love to the people in need, you are fashionable.
to protect the environment is fashion. if you don't use the plastic bags and do something to protect our earth, you are fashionable.
so let's form good personal qualities. let's follow the fashion.
With the development of the modern technology，private car is no longer a luxurious thing for ordinary people，more and more people drive to work instead of going by bus. The popularization of private car has many advantages.First，it is very convenient and time-saving，you can drive your own car to the workplace instead of waiting for the crowded bus and afraid of being late for working.Second，it can also improve the traffic structure，and help to mitigate the stress of the traffic.Third，the popularization of private car can help to promote the car industry and any other interrelated industries. I believe that in the future the private car will become the most important vehicle and we cann't live without it.
Parents gave me life in this world,I love the most is them.
Expressing of loving parents do not need to pass a language that I ever we can do some little the Father's Day or Mother'sDay,we can prepare a delicious breakfast for can remember their birthdays,we don't need to buy gifts,but have to say happybirthday.
When parents come home from work,we can hand them a cup of hot water to makethem can help parents to share some of the housework,so that they havemore time to part of the family,we should take active to do read out,we should always contact them,tell them recent things of our hem not worry about us.
It is known to all our parents love is priceless,is not asking should love them in return. But,parents can be very simple ng as the life of more concern to them,for them to have been do it.
My mom is about 45 years old.She has long hair and very big eyes. She is ahousewife. She always helps me with my homework before she cleans the house andprepares dinner for my whole family. She is really a nice and kind mother.
My mom is always very reasonable. All she asks for is for me to complete myschoolwork. If I get a good mark on my test,she will be very happy. If I don'tdo well,she won't get angry. She will encourage me to do better next time.
I love my mom,so I give her a hug when I get home,and tell her she is thebest mom in the world.
the english speech about success
i’m glad to be here to share with you my definition of success.
when we mentioned the success, the usual worldly criteria are wealth, fame, high social status and something other like that. in reality, we can’t deny t these things in some way. but personally, i believe that success is the realization of people’ hopes and wishes. and to live with a high ideal is a successful life. it is not what one does, but what one tries to do, that make a man strong. so i believe that success is ninety-nine percent mental attitude, it calls for lots of positive quality: effort, love, diligence, efficiency and so on. i think the successful life always have these characters. if a person inherits his family’s millions and leads an easy life, he is not a successful person in material terms, it just can be said that he has the smooth way of life, he is lucky in some way, but that is not the success .unceasing effort is the price of success. no matter what is the result, we always can get more from the process. what we should do is that insisting on our goals or dreams and always encourage
ourselves to challenge more, to hold the opportunities, never give up. it sounds like simple, but it is really hard to do. also the key points of the success.
relatively speaking, in our daily life, success would be rather simple. for me, i’m standing here to take part in the speech competition is somehow also success. as i’m a easy to suffer from stage fright, i choose to hold this chance, my goal is my own character training——to be more confident, to have more courage to front such situation, i really do it, i have truly gained by participating, i’m success.
what is success? i’m sure that everyone has his own interpretation as i do. in the inspiring words of philips brooks:“ do not pray for tasks equal to your powers ,pray for powers equal to your tasks, then the doing of your work shall be no miracle, but you shall be the miracle.” so believe in our hopes ,believe in ourselves. every one can create the success.
thank you!
Hello! i wonder whether everybody knows the meaning of these two words of " energy-conservation " and " low carbon "? i assume as a matter of course and know. does " energy-conservation " save the energy? does " low carbon " reduce carbon emission? yes, it is really simple. we often chat about them. but, do you really understand them? have they really taken root on your bottom of heart deeply?
Once, the earth mother left our rich energy to cause us to be jubilant, sighed on earths energy inexhaustible, inexhaustible, now, the newest statistics indicated, the petroleum will dry up after 60 years, the coal also might supply the humanity to use for 250 years; once, developed first, the environment question the situation which neglected is often occurred, now, the sustainable development, was together harmoniously with the nature the biggest topic.not difficult to see, the environment question in is taken unceasingly by the people.for all this, the environment question was still stern, the energy conservation reduced the platoon, the low-carbon lives imminently.at the copenhagen climate congress, this affects the human destiny the question slowly to be unable to reach the agreement actually.in the life, is driving the great displacement automobile, purchases including the fluorine air conditioning, the refrigerator, including the phosphorus laundry powder, turns on the air conditioning the low temperature also one side to bind in the summer the quilt, the daylight lamp is being long all night clearly, water cock water drop sound day and night not rest.these influence environment phenomenon common occurrence.this is rebels with ours position. american president kennedy has said: do not have to ask the country can make any for us, must ask first oneself can make any for the country.the low-carbon life needs everybody to participation!
The low-carbon life first is one kind of life manner.so long as wants, each person may be able to achieve! the electricity saving, saves gas and oil, the solar terms, saving water, the tree-planting, makes use of waste, by step generation of vehicle.the intravenous drip, in life each aspect, all may choose the low-carbon life the manner.the low-carbon life is also representing one kind healthily, the more natural life style.little eats counter-season food, the generation by works as season food; little uses the disposable product, the generation by the duplicated things; little rides an overhead traveling crane, little sits one time the elevator, the generation rides the bicycle, crawls the staircase, while falls the low-carbon withdrawal, we will have a healthier body and mind.
We believed, so long as everybody works as one, participation together, humanitys tomorrow certainly will be able to be happier! schoolmates, today, your low-carbn.
Good morning,ladies and gentlemen,today i am so happy to stand here to give you a rather, a real story of mine.
Though with time going by,i can still remember what you once told should be a brave ing,you looked into my in,year out,nearly most of my memories are fading little by only this simple sentence remained,without being forgotten in my life.
Again and again,i can not stop myself from thinking about ordinary,but so impressive,so moving,just like the brightest sunshine,it helps me go through the darkest night.I am such a sensitive girl in your said,my sorroful facial expression made feel so ver,there is one thing i never tell you,that is ,i am becoming a big girl gradually with your words and smiles.I never tell you about it,for i believe oneday,you can see the great changes of mine for is what i want to do in i know,that will be the best gift for you.
I suddenly think of a song named MY HEART WILL GO e is a beautiful sentence going like are safe in my than once,i was moved to tears by it.I know ,i am also safe in your heart.i have already forgotten when i told you i was going to leave for Australia this summer just smiled as usual,gently ever you decide to do,i will be in favor of it,but, just onething,remember,when you fell lonely abroad,do not forget we are here ,praying for are all around you,far across the distance and space between us.i closed my eyes,the flashback memories we had together,once we played games on the palyground,we played jokes on each other,you always wrote a lot of sentences on my articles to encourage the most unforgetable thing,you told me,you believed m i could be a big er or later.
At that specific moment,i suddenly understood the meaning of this sentence on that day,i smiled as you used to,looking at last words i said were,keep walking in sunshine.
Yes,keep walking in sunshine.I said to you ,also to myself.I know i am not alone wiht your company,and we can keep walking in sunshine till the last minute of our days.
I promise,i will be a big girl.
How to Stay Healthy How to Stay Healthy
nothing is more valuable than health. it is the foundation of one’s future success. generally speaking, a Healthy person can always be energetic and enjoy his life and achieve what he hopes for in his career. on the contrary, poor in health, a person can not achieve much though he is well-educated. then, what should we do to maintain and enhance our health and do you know to keep Healthy? let’s start in three aspects------keep a balanced diet, give up bad habits and take regular exercise.
firstly, keep a balanced diet. scientific research sHows us How a balanced diet is made up-----a pyramid. the lowest floor sHows us the main food we need at least 300g everyday. like, bread, rice, noodle etc. the second floor contains vegetables and fruits which are full of vitamin c and vitamin e and other nutrition good for our health. we should eat it more than 400g in our diet. the third floor has meat, fish and egg that we often eat in our daily meal. but we should be cautious about these foods and eat less than 100g. the fourth floor which is soy-based food and dairy products which is easy to get us fat for its high caloric. 70 g is enough. the top floor sHows oil and salty products we should eat only 30g or 50g at most. if each meal we eat following this balanced diet, eating Healthy, i believe we can be Healthy and keep a nice figure.
secondly, give up bad habits. as we know, drinking too much is harm to our stomach; smoking is bad to our lung. it also reported that every year more than 110 thousand people was poisoned then killed by alcohol in china and more than 3.5 million people in the world are killed by diseases because of smoking. so we should drink less and stop smoking. as a teenager, we often Stay up to prepare our next day examination or play puter games that not only cost our time but also kill ourselves. we should give up these bad habits and make a balanced schedule to keep a good state.
finally, take regular physical exercise which is essential for a relaxed mind and body. taking frequent exercise, can improve and balance the function of your heart and lung, prevent osteoporosis, burn the flab, enhance metabolism and strengthen
immunity, relieve pressure of study or work. for example, yoga can improve your rate of breath by calming down your mind and body, and get rid of distractions and tenacity to concentrate on certain item. what’s more, it help you keep a perfect figure by strengthen your arm and get every joints of your body active and relax your body. now, this kind aerobic activity is popular which include swimming, riding, jogging and yoga etc. so, let’s join sports to keep fit.
in conclusion, if everyone can stick to what is mentioned above, keep a balanced diet, give up your bad habits and take regular exercise, then you will be perfect and Healthy.

Last summer vacation I went to Beijing with my family .
First day,we went go the Great Wall because it is the pride of our Chineseand a wonder in the world.
Then we went to the summer palace We saw many beautiful sceneries there.The next day we went to the Tian'anmen square ,and we tasted Beijing duck.
In the afternoon we went to the bird's nest and the water cube.Though wewere tired we were very happy.
I learned much knowledge that I can't learn in the textbooks so I willnever forget this interesting trip.

Good evening,ladies and gentlemen：
Thank you very much for choosing to e in such a cold night.today my topicis about choice and process.a research shows that a man has to make 73 choicesone day.with so many choices one day,people easily get so confused and afraidof making wrong choice that they hesitate and finally miss the true part oflife. in my opinion,the following part is of much more importance than thechoice. there is no absolute right or wrong choice but wonderful or boring life,which the process makes the difference.
Life is a box of chocolate,you never know what you will get. forrest gumpmade no decision by and for himself but he acplished great success with hisstrong will in the process. the process is not the road itself but the attitudesand feelings,the caution,courage and persistance we have as we encounter newexperience and unexpected obstacles. take myself as an example,i changed mymajor when i became a postgraduate. after the choice,days have been harsh forme.i cannot understand the new lessons at all. for they are closely related tomathmatics which i learned nothing about before. however wuth the belief thatthis is the great chance for me to experience new ideas and challenge myself,ipersisted. i asked for help from every channel and reorgonized my life.gradually i could understand some parts and even found mathsinteresting.moreover,i learned to act instead of plaining. in retrospect,thechoice left no trace in my mind but the happiness and bitterness of the pastfour months bees an unforgetable experience in my life.
No matter what the choice is,enjoy the process. in the process,yourpotential will be inspired and new discoveries,improvement and progress will eto you. these are the most beautiful sceneries and only on the way can you seeit.these make your life colorful.
There is no need and i donnot want to judge whether it right or wrong forme to be here,but i congratulate to myself for i gain and enjoy this fantasticexperience. so my dear friends,never worry about your choice and enjoy theprocess. i am sure you will get something new and intersting tonight after youchose to e here.
Thank you!
Good morning everybody! my name is dubin. its my honor to speak here, today id like to talk something about energy conservation and emission reduction! and i am very glad to share my idea on this topic with you. there are three parts in my presentation,and it will last about 10 minutes.please be free to ask if you have any question.
So,first of all,i’d like to show you the current situation of energy using. energy conservation and emission reduction means to save energy and reduce harmful gas emission. with the development of science and technology, our life has become more and more colorful. however, it is also associated with huge energy consumption.
Here is a picture, it shows that with the continuous development of human society, our consumption of energy is more and more huge. as we know, nowadays, our main source of energy is non-renewable resource. its storage capacity is very limited, and most of them have been used , and still being consumed very quickly .
Here is a bar chart , from which we can be aware of the importance and urgency of energy saving in addition, there are some picture about the greenhouse effect. because a large amount of greenhouse gas emission, global temperatures are rising .it give cause to the rise of sea level ,and natural disasters is frequent…..
Now,let’s turn to the second part,why is energy saving so important?in order to let the world be still beautiful, we need to do something .for one thing, energy conservation and emission reduction will slow down the energy consumption, and save the resources; for another, we are also protecting the environment at the same time,it can reduce greenhouse gas and other harmful gas emission. according to the survey, in our country, coal accounted for 80% of total electricity, but coal will produce large amounts of greenhouse gases.
So,the most important part is coming,in our daily life,how can we save energy? there are many ways, such as: turn off the lights when you needn’t, drive less and walk more , save pa-pe-r, plant more trees.
Guys, in order to let the grass become greener, the sky become bluer, the environment become cleaner.from now on, we must learn to do everything we can to save energy. come on! ok,this all .thanks for your listening!
What I'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.
Now, there is a sound -- (Alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. And what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep. If you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.
Now what that 32 years is telling us is that sleep at some level is important. And yet, for most of us, we don't give sleep a second thought. We throw it away. We really just don't think about sleep. And so what I'd like to do today is change your views, change your ideas and your thoughts about sleep. And the journey that I want to take you on, we need to start by going back in time.
"Enjoy the honey-heavy dew of slumber." Any ideas who said that? Shakespeare's Julius Caesar. Yes, let me give you a few more quotes. "O sleep, O gentle sleep, nature's soft nurse, how have I frighted thee?" Shakespeare again, from -- I won't say it -- the Scottish play. [Correction: Henry IV, Part 2] (Laughter) From the same time: "Sleep is the golden chain that ties health and our bodies together." Extremely prophetic, by Thomas Dekker, another Elizabethan dramatist.
But if we jump forward 400 years, the tone about sleep changes somewhat. This is from Thomas Edison, from the beginning of the 20th century. "Sleep is a criminal waste of time and a heritage from our cave days." Bang. (Laughter) And if we also jump into the 1980s, some of you may remember that Margaret Thatcher was reported to have said, "Sleep is for wimps." And of course the infamous -- what was his name? -- the infamous Gordon Gekko from "Wall Street" said, "Money never sleeps."
What do we do in the 20th century about sleep? Well, of course, we use Thomas Edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost. We've treated it as an enemy. At most now, I suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure. And our ignorance about sleep is really quite profound.
Why is it? Why do we abandon sleep in our thoughts? Well, it's because you don't do anything much while you're asleep, it seems. You don't eat. You don't drink. And you don't have sex. Well, most of us anyway. And so therefore it's -- Sorry. It's a complete waste of time, right? Wrong. Actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's so very important. So let's move to the brain.
Now, here we have a brain. This is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (Laughter) Sorry. So I borrowed it. I don't think they noticed. Okay. (Laughter)
The point I'm trying to make is that when you're asleep, this thing doesn't shut down. In fact, some areas of the brain are actually more active during the sleep state than during the wake state. The other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back -- I love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. The biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. All of those combine, and they send projections down to the brain stem here. The brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. So sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range of
Okay. So where have we got to? We've said that sleep is complicated and it takes 32 years of our life. But what I haven't explained is what sleep is about. So why do we sleep? And it won't surprise any of you that, of course, the scientists, we don't have a consensus. There are dozens of different ideas about why we sleep, and I'm going to outline three of those.
The first is sort of the restoration idea, and it's somewhat intuitive. Essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. And indeed, as an explanation, it goes back to Aristotle, so that's, what, 2,300 years ago. It's gone in and out of fashion. It's fashionable at the moment because what's been shown is that within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways. So there's good evidence for the whole restoration hypothesis.
What about energy conservation? Again, perhaps intuitive. You essentially sleep to save calories. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. So I'm less convinced by the energy conservation idea.
But the third idea I'm quite attracted to, which is brain processing and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. It's really hugely attenuated. So sleep and memory consolidation is also very important. However, it's not just the laying down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night enhances our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.
Okay. So we've had three explanations for why we might sleep, and I think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons. But sleep is not an indulgence. It's not some sort of thing that we can take on board rather casually. I think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of. It's not even an upgrade from economy to first class. The critical thing to realize is that if you don't sleep, you don't fly. Essentially, you never get there, and what's extraordinary about much of our society these days is that we are desperately sleep-deprived.
So let's now look at sleep deprivation. Huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter. So in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night. Nowadays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours-every-night league. For teenagers, it's worse, much worse. They need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. It's simply not enough. If we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night. Shift work. Shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night. It's locked onto the same light-dark cycle as the rest of us. So when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, "Wake up. This is the time to be awake." So the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region. And then, of course, tens of millions of people suffer from jet lag. So who here has jet lag? Well, my goodness gracious. Well, thank you very much indeed for not falling asleep, because that's what your brain is craving.
One of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it. Now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly. It's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the U.S., the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep. A hundred thousand a year. It's extraordinary. At another level of terror, we dip into the tragic accidents at Chernobyl and indeed the space shuttle Challenger, which was so tragically lost. And in the investigations that followed those disasters, poor judgment as a result of extended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.
So when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment. But my friends, it's so much worse than that.
(Laughter)
If you are a tired brain, the brain is craving things to wake it up. So drugs, stimulants. Caffeine represents the stimulant of choice across much of the Western world. Much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine. And of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, "Ah, well actually, I need to be asleep fairly shortly. What do we do about that when I'm feeling completely wired?" Well, of course, you then resort to alcohol. Now alcohol, short-term, you know, once or twice, to use to mildly sedate you, can be very useful. It can actually ease the sleep transition. But what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep. It sedates you. So it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall. So it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.
Another connection between loss of sleep is weight gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. Ghrelin is released. It gets to the brain. The brain says, "I need carbohydrates," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain.
Stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. So sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer. Increased levels of stress throw glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress increases cardiovascular disease as a result of raising blood pressure. So there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where I think most people think that sleep loss resides.
So at this point in the talk, this is a nice time to think, well, do you think on the whole I'm getting enough sleep? So a quick show of hands. Who feels that they're getting enough sleep here? Oh. Well, that's pretty impressive. Good. We'll talk more about that later, about what are your tips.
So most of us, of course, ask the question, "Well, how do I know whether I'm getting enough sleep?" Well, it's not rocket science. If you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived. Listen to them. Listen to yourself.
What do you do? Well -- and this is slightly offensive -- sleep for dummies: Make your bedroom a haven for sleep. The first critical thing is make it as dark as you possibly can, and also make it slightly cool. Very important. Actually, reduce your amount of light exposure at least half an hour before you go to bed. Light increases levels of alertness and will delay sleep. What's the last thing that most of us do before we go to bed? We stand in a massively lit bathroom looking into the mirror cleaning our teeth. It's the worst thing we can possibly do before we went to sleep. Turn off those mobile phones. Turn off those computers. Turn off all of those things that are also going to excite the brain. Try not to drink caffeine too late in the day, ideally not after lunch. Now, we've set about reducing light exposure before you go to bed, but light exposure in the morning is very good at setting the biological clock to the light-dark cycle. So seek out morning light. Basically, listen to yourself. Wind down. Do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.
Okay. That's some facts. What about some myths?
Teenagers are lazy. No. Poor things. They have a biological predisposition to go to bed late and get up late, so give them a break.
We need eight hours of sleep a night. That's an average. Some people need more. Some people need less. And what you need to do is listen to your body. Do you need that much or do you need more? Simple as that.
Old people need less sleep. Not true. The sleep demands of the aged do not go down. Essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.
And the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise. Well that's wrong at so many different levels. (Laughter) There is no, no evidence that getting up early and going to bed early gives you more wealth at all. There's no difference in socioeconomic status. In my experience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.
(Laughter) (Applause)
Okay. So for the last part, the last few minutes, what I want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption. We've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored. In the 1970s, when people started to think about this again, they said, "Yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics. It's the anti-psychotics causing the sleep problems," ignoring the fact that for a hundred years previously, sleep disruption had been reported before anti-psychotics.
So what's going on? Lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption. We have a big study which we published last year on schizophrenia, and the data were quite extraordinary. In those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day. Other groups showed no 24-hour patterns whatsoever. Their sleep was absolutely smashed. And some had no ability to regulate their sleep by the light-dark cycle. They were getting up later and later and later and later each night. It was smashed.
So what's going on? And the really exciting news is that mental illness and sleep are not simply associated but they are physically linked within the brain. The neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping. And what's the evidence for that? Well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems. And last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep. So we have evidence of a genuine mechanistic overlap between these two important systems.
Other work flowed from these studies. The first was that sleep disruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar. The other bit of data was that sleep disruption may actually exacerbate, make worse the mental illness state. My colleague Dan Freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.
So what have we got? We've got, in these connections, some really exciting things. In terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain. The second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in. If we know that these individuals are vulnerable, early intervention then becomes possible. And the third, which I think is the most exciting, is that we can think of the sleep centers within the brain as a new therapeutic target. Stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.
So let me just finish. What I started by saying is take sleep seriously. Our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet. We used to understand intuitively the importance of sleep. And this isn't some sort of crystal-waving nonsense. This is a pragmatic response to good health. If you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health. If you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendency to drink and take drugs. And we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.
Jim Butcher, the fantasy writer, said, "Sleep is God. Go worship." And I can only recommend that you do the same.
Thank you for your attention.

good afternoon, ladies and gentlemen. good afternoon, boys and girls. good afternoon, everybody. i ’m glad to make a speech here.
as we all know, tomorrow is teachers’ day. many people say that teachers are not unusual at all. that’s true. but i want to say though teachers are common, their job is unusual. what they do is very very great. i am an english teacher. so i’ll make an english speech here. and my topic is “live with thankfulness”. do you know what “thankfulness” means in chinese? it means “gan’en”.

In recent years, college students find it increasingly difficult to get a job. It sounds strange since young college students are usually intelligent, well-educated phenomenon, aspirant and eager to bring their talent into full play. Then what underlies the strange phenomenon? high. All they want are “good” jobs which could offer good salary, comfortable working conditions, high social status among others. Consequently, most college students are unwilling to accept vacant jobs they consider not “good” enough. Another reason is that there is a big gap between the majors some students study in school and the demands of vacant jobs. So companies think some students are not fit for the jobs.
Solution to the problem requires efforts on both the society and the students. The companies should value the students, talent and knowledge while the latter should not merely aim at material gains. They should be down-to–earth in building up their career. Furthermore, they should face their weak points so as to improve themselves and be more competent.
it’s a very intresting topic today.
i think my dad was a hero for me when i was a young child. we'd go fishing, walks, and other fun things for a kid.
every child has a good and great father, and so do i. my dad played a very important role in my daily life`````exactly speaking, in my past 16 years.
my father always stands in the center of my life，from past till now and possibly in the future.
my family was rather poor when i was in my childhood. we didn't have our own house and had to live in a shabby，small room rented from my father's factory. the room was so small that there was little space for people to walk. i didn't have my own bed and had to sleep with my parents. this is terrible both for my parents and me.
but father made this all different!he works very hard on his own business, now we have our own 2 housese,surly,i have my own room.and he take our family so much happiness, richer and richer.
when i was little, i did everything with my dad. you could always find me sitting on his knee or walking and doing everything with him. every night he would read me a bed time story and make the voices of each character.
i learnt a lot from my daddy. i learnt to never take things to seriously and to always smile.
like many other fathers, my dad and i also has generation gap. he is not good at or even can’t work the computer. so when i sitting at the computer desk,he will say something like ‘you should pay more attention to your study’, ‘don’t waste time on the computer games’ , ‘it will be bad for your eyes’ and so on. how can i- a computer fan – reduce time on computer? so i continue studying and playing on it
years pasted, my father is over 45 now. it is time for me to look after him and i am sure i will do and we will live an even better life. and i will say,i really love you dad,cause you are the hero in my mind.
thank you so much!

what college education means to me.
the title of my speech is “what college education means to me”.now reflecting on the past two and half years of my college experience, i come to realize how much it has shaped me.
for me, college education is a marvelous ship-builder who designed me from kneel plates up.
with great vision, college education has equipped me, first with a powerful propeller----the sophisticated knowledge in certain field and wide exposure to other disciplines. by dedicating myself to the engineering courses in the day and immersing myself in the rich banquet of the world literature at night, i’ve amassed the driving force for the future and enriched my soul.
besides, college education has also provided me with a precise compass----the sense of social responsibility. how can i best serve the interest of the public while achieving my self-fulfillment? my one year’s experience as a part-time english teacher has testified: to be valuable to society as well as to find my place, i have to possess some actual strength and the ability to function well in the most challenging situation. amid the hectic schedule that balances club activities, sports, and academic courses, i feel the rhythm and beauty in the intensity of my high-pitched life, knowing that i ’m on the right way.
and more importantly, college education has set up not only single ships, but also fleets with common destinations. by interacting with friends of common beliefs, i’ve acquired skills of relating to other people.
now ,as a ship about to make my maiden voyage ,i’m still not in the position to tell what’s waiting ahead of me ,but with a powerful propeller, a precise compass and ardent companions of sailing in the sea of society, i’m ready to be a great sea-explorer.
thank you.
