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 (親自) some day.

　　Best wishes,

　　Yours,
