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.
