介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。下面是小编精心为大家整理的定语从句的经典例句通用9篇，希望可以启发、帮助到大家。
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词， 对其进行修饰， 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。
作者：郭克晴
在复合句中起定语作用、修饰某一名词或代词的从句称为定语从句，被修饰的名词或代词称为先行词。定语从句由关系代词（that, which , who, whom等）和关系副词（when, where, why等）引导，位于先行词之后。关系代词在从句中作主语、表语、宾语或定语。在这里我们只简单介绍关系代词在定语从句中的用法：
1.先行词指物时，关系代词常用that或which。如：
China is a country which/that has a long history. 中国是个具有悠久历史的国家。（which/that代替先行词country，在从句中作主语。）
I always remember the stories which/that my mother told me during my childhood. 我总是记得童年时母亲给我讲的故事。（which/that代替先行词stories，在从句中作told的宾语。）
2. 先行词指人时，关系代词用who， whom， whose或that。
The students who studies hard is not afraid of the examination. 学习用功的学生不怕考试。（who代替先行词student，在从句中作主语。）
This is the girl who/whom you want to see. 这就是你想见的那个女孩。（who/whom代替先行词girl，并在从句中作see 的宾语。）
This is the boy whose bag was lost yesterday. 这就是昨天丢失了书包的那个男孩。（whose代替the boy's，在从句中作定语。）
1)what = the thing which;whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
(错)Who breaks the law will be punished.
(错)Whoever robbed the bank is not clear.
(对)Whoever breaks the law will be punished.
(对)Who robbed the bank is not clear.
3) that 和 what
当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从 句， 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.
关系代词as与which引导的非限制性定语从句，其先行词都可以是整个主句，指代主句的整个意 思。但as和which具有不同的词义、句法和用法。
1、 as引导的从句表示说话人的看法、态度、解释或评论
引导定语从句时，as仍具有正如，像，由……可知等意思，翻译时 有时可不必译出。as定语从句常含有这些动词：see， know， hear， watch， remember， say， tell， show， expect， guess等，这类动词与as连用几乎成了一种固定搭配。as引导的此类从句可以置于句首、句中或 句尾。如：
The famous magician Liu Qian， as we all know， is from Taiwan. 众所周知，著名魔术师刘 谦是台湾人。
There is a net bar around here， as I remember. 我记得这儿附近有一家网吧。
As is often the case， girls like dolls while boys like guns. 女孩子喜欢玩具而男孩子 喜欢枪，这是常见的情况。
2、 which引导的从句对主句所叙述的事情进行补充说明，表明事物的状态或结果
which此时指前面主句所提到的这件事，常译为这一点，这件事等。这时它所引 导的从句与主句之间常含有并列、因果关系。注意，它引导的从句不像as那样位置灵活，它只能位于主句 的后面。如：
He changed his mind again， which made us all angry. 他又改变了主意，这使我们大家都生 气了。
She tore up my photos， which （=and that） upset me.她撕碎了我的照片，这使我很不安。
3、 在从句中作定语或介词的宾语时，要用which，不用as
Jenny might come， in which case I‘ll ask her. 詹妮可能会来，要是那样的话我就去问 她。
She graduated from a local middle school， after which she went to Beijing University. 她毕业于当地的一所中学，之后她去了北京大学。
4、 当从句的谓语动词是否定形式或含着一个复合宾语时，一般用which而不用as
He pretended not to know me， which I didn’t understand. 他假装不认识我，这是我搞 不明白的。
He admires everyone in his class， which I find quite strange. 他羡慕班里的每个学生， 我认为太奇怪了。
【特别说明】
as引导非限制性定语从句的最大特点是位置灵活；其次，as有以下常见的，而which不具备的 固定表达：
as we all know 众所周知
as I can remember 正如我所记得的
as often happens 正如经常发生的那样
as we expect 正如我们预料的那样
as you see 这一点你明白
as was expected 正如预料的那样
as can be seen 看得出来
as may be imagined 正如可以想象的那样
as has been said above 如上所述
as we all can see 正如我们都能看到的那样
as is often the case 像常规那样
as everybody can do 正如人人都能做到的那样

典型例题
1)Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。
定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which等。
关系副词有：when, where, why等。
1.关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗？（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）
2) Whose 用来指人或物，(只用作定语， 若指物，它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。
3）which, that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）
2.关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
3.判断关系代词与关系副词
方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示 出。）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D,例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D.
而句2中， 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where,又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A.
关系词的。选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) .
4.限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词， 对其进行修饰， 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。
5.介词+关系词
1）介词后面的关系词不能省略。
2）that前不能有介词。
3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
6.as, which 非限定性定语从句
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that.As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
典型例题
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.,it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B.which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which C. as D. it
答案B.
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1） as 引导的定语从句可置于句首，而which不可。
(2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which..
在本题中，prevent由于是行为动词，所以正确选项应为B.
As 的用法
例1. the same… as；such…as 中的as 是一种固定结构， 和……一样…….
I have got into the same trouble as he (has).
例2. as可引导非限制性从句，常带有'正如'.
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。
7.先行词和关系词二合一
1)Whoever spits in public will be punished here.
(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.
(what 可以用all that代替)
8.what/whatever;that/what; who/whoever
1）what = the thing which；whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
（错）Who breaks the law will be punished.
（错）Whoever robbed the bank is not clear.
（对）Whoever breaks the law will be punished.
（对）Who robbed the bank is not clear.
3) that 和 what
当that引导定语从句时 ,通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从 句， 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.
9.关系代词that 的用法
1）不用that的情况
a) 在引导非限定性定语从句时。
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用。
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中，只用that,不用which.
b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that,不用which.
c) 先行词有the only, the very修饰时，只用that.
d) 先行词为序数词、数词、形容词最高级时，只用that..
e) 先行词既有人，又有物时。
举例：
All that is needed is a supply of oil.
所需的只是供油问题。
Finally, the thief handed everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察。
1、 A. which用作关系代词，在定语从句中作主语。
2.C. "和谁讲话"要说speak to sb. 本题全句应为Do you know the man whom I spoke to.。whom是关系代词，作介词to的宾语，可以省略。
3、 D. where是关系副词，表示地点，在定语从句中作地点状语。
4、 C. when是关系副词，表示时间，在定语从句中作时间状语。
5.A. which是关系代词，在从句中作forget的宾语。其他几个答案都不能作宾语。
6.C. 解析同第5题。
7、 A. 解析见第3题。
8、 A. 本句话的先行词应该是films,因此，关系代词that是负数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面使用了定冠词the，则the one应该视为先行词。
9、 A. "谈到某事物"应说talk about sth.。about是介词，其后要用which作宾语，不能用that。
10、 A. with which是"介词+关系代词"结构，常用来引导定语从句。with有"用"的意思，介词之后只能用which,不能用that. with which在定语从句中作状语，即he is writing with a pen.
11、 C. in front of which 即in front of a farmhouse. In front of which在从句中作状语。
12、 D. with whom引导定语从句。with whom放在从句中即为:my father works with the engineer.
13、 D. whose引导定语从句，在从句中作主语family的定语。
14、 A. that引导定语从句，因为先行词是all,所以只能选用that引导。
15、 D. the same.。.。.。.。as是固定用法， as引导定语从句时，可以作主语，宾语或表语。在本句话中，as作从句的主语。
16、 D. such.。.。.。.。. as是固定用法，as引导定语从句时，可以作主语，宾语或表语。在本题中，as作表语。
17、 B. as作关系代词可以单独用来引导非限制性定语从句。这时as所指代的不是主句中某个名词，而往往指代整个主句的含义。as在从句中可以作主语、宾语。从句可放在主句后，也可置于主句前。在本句中，as作宾语。
18、 B. Li Ming enjoyed it very much是主句，with whom I went to the concert是定语从句。with whom放在从句中为:I went to the concert with Li Ming.
19、 C. as引导定语从句时通常构成such.。.as或the same.。.as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。 as在从句中可以作主语、表语或宾语。Such修饰单数名词时，要用such a.。.。.。.。，本题中such books, such直接修饰复数名词。
20、 B. things和persons是先行词。当定语从句要修饰的先行词是既表示人，又表示物的名词时，其关系代词要用that.
21、 D. who引导非限制性定语从句，who作从句的主语。
22、 C. two thirds of whom 即:two thirds of the 2,000 workers.
23、 D. 先行词person后有两个定语从句，第一个从句省略了关系代词whom.因为， whom作从句中met的宾语，可以省略。第二个从句who could do it.who在从句中作主语，不可省略。
24、 A. whose title引导非限制性定语从句，whose title也可以说成the title of which
25、 A. for which 引导定语从句，使用介词for,是来自于从句中的固定短语 be famous for "以。.。.。.。.而闻名"。
26、 C. 当先行词被such修饰时，引导定语从句的关系代词要用as. As在本从句中作主语。
27、 A. 两个先行词the day都是表示时间的名词，但第一个空白处要填的关系词在从句中作状语，因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语，因此要用关系代词which或that来引导定语从句。
28、 D. 在way、distance、direction等词后的定语从句中，常用that来代替"in （或其他介词）+which"、when或where，而that常可省略。

44、 D. that followed是定语从句，关系代词that在从句中作主语。
45、 A. 先行词gas被only修饰，关系代词要用that，而不用which。
46、 B. through which引导定语从句，through which即through the hole,在定语从句中作状语。What引导的是see的宾语从句，并作从句的主语。
47、 B. 为便于理解，改写本句话：This is the school that some Germanfriends visited last week. 不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited的宾语，所以被省略了。其它选项结构不对。

49、 C. 因为是two ballpens, 并且定语从句的谓语writes是单数概念。因此，C是正确选项。
50、 B. 本句话中，主句的主语是all,为抽象概念。因此，其谓语应用单数的has been。关系代词that引导定语从句，并在从句中作主语。
