    Hello, I'm Ann. I have a beautiful school. It's not big. There are 18 classrooms in it. My classroom is next to the library. It's big and clean. Teachers work in the teachers' rooms. There is a playground, a library, a computer room, an art room, a music room and six teachers' rooms in my school. The playground is in front of the school building. We play games there. The computer room is between the music room and the art room. We have computer lessons in the computer room. We sing songs in the music room. We draw pictures in the art room. I like my school very much.

    There are five people in my family. We are all teachers. My grandfather is an English teacher. He has many English books. My grandmother is an art teacher. She has many crayons. My father is a maths teacher. He has a computer. My mother is a music teacher. She has a piano(钢琴). I am a PE teacher. I have a ball.
