Jim,

     I was pleased to hear from you and I am written to tell you something about the changes in my school.

     You are right. Great changes have been taken place in my school. It is not longer what it used to be

three years ago, when there were only one teaching building and a playground. I am happy to tell you two new buildings have been built and are on use. One of them is a new classroom building, in it there are

rooms for music, arts and computer teaching. The other is a library, where there are all kinds of books,

newspapers and magazines. However, my school is good equipped with sports facilities and musical

instruments. The number of students has also grown from 1,500 to 2,500. What's more, we had planted

a lot of trees and flowers in and around the school.

     I believe my school become better and better, and I hope you will visit my school again.

                                                     Yours,

                                                      Li Hua
