Dear parents，
Words fail me when I want to express my thanks to you. You have taken good care of me since I was born.When I am in trouble，you always encourage me and cheer me up.Once I argued with my best friend and was upset，you talked with me the whole night and finally helped me solve the problem. With your help，I have become a good student.I am so thankful for your love that I will work harder and try to do better in the future。
Best wishes。
Yours，

Dear Mr Smith,
I was so pleased to hear from you and I am writing to tell you something about my school.
You are right.Quite a few changes have taken place here.On one side of the road there's a new classroom building. On the other side,where the playground used to be,now stands another new building-our library.In it there are all kinds of books,newspapers and magazines.The playground is now in front of the school.We have also planted a lot of trees in and around the school.I hope you come and see for yourself some day.
Best wishes,
Yours,

Dear teacher，
Words fail me when I want to express my thanks to you. You have taken good care of me since I came to this school. When I am in trouble，you always encourage me and cheer me up. You are kind but strict with us，you never allow us to pretend that we know what we don't know. You often tell us that it's no use memorizing new words without understanding. With your help，my English has greatly improved. Thank you for caring about me，I will work harder in the future。
Best wishes。
Yours，
