We have twenty minutes' rest between classes. Look! Most of us are playing during the break time. Some students are on the playground. They are playing basketball. Oh! A boy is running with the ball. And another is trying to stop(阻止) him. They look so cool. And there are some girls watching the game. Some students are in the classroom. They are talking.

What are the teachers doing? Some of them are working in the office. And some are talking with students. Everyone is doing his or her things. They are busy but happy.
