     Look! This is a picture of our classroom. There are fifty desks and chairs in it. They are for students.  

On the desks are our books. There is also a big desk in the classroom. It's for our teachers. Under the

teacher's desk, there are two basketballs and a football. We can play basketball and football after class.   What other things can you see? Yes, there are two maps on the wall, a map of China and a map of the

world. Our classroom is very nice. I like it very much.
