In our school, we have four classes in the morning. From nine forty to ten o'clock, we can have a twenty-minute rest time. It is a quarter to ten now. Look! Most of us are going out of the classroom. Some boys are playing basketball, soccer or running on the playground. Some girls are watching them or playing badminton. There are also some students in the classroom. They are talking. A few of them are reading or doing homework. Look! A girl is looking at the birds in a tree from the window. She is smiling.

    What are our teachers doing? They are either working or talking to the students in the office. They are all very busy but happy!
