Dear Zhang Peng,

    I have a new school. It's big and beautiful. There are many trees and beautiful flowers in it. The school buildings are yellow and white. We have a music room, an art room, a computer room and a library. I'm in Classroom 1. It's on the first floor. It's next to the library. I like our playground very much. It's so big , we often play football there.

    Welcome to my school!

Yours,

John
