We have four classes in the morning. Between the second class and the third class, we have a twenty minutes’ rest. Now it's the rest time. Look! Many of us are playing. Some boys are on the playground. They are playing basketball. Oh! A boy is running with the ball. And another is trying to stop him. They look so cool. And there are some girls watching the game. Some students are in the classroom. Most of them are talking. Four students are reading and doing homework. There's a tree not far from the classroom. Look! A girl is looking at the birds in the tree. She must think the birds are interesting because she is smiling.
