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 (亲自) some day.

　　best wishes,

　　yours,

　　li hua
