My name is Jeff. I'm English. But now I live  in China. I am a student. This is my classroom. Fifteen small desks and thirty chairs are in the classroom. They are for  classmates and me. A big desk is in the classroom, too. It's for my teacher. A clock is on the back wall of the classroom. Next to the clock is a map. It's a map of China. My classroom is nice and clean. I like _ very much. What's on the back wall of the classroom?
