     Schools in the U.S.A are a little different from schools in China. Usually, there is no school uniform.

In many Chinese schools, students have school uniforms. Classes start at 8: 30 each morning and the

school day ends at 3:30 or 4 o'clock in the U. S. A. And in China, classes usually start at 8:00 in the

morning and the school day ends at 5:30 in the afternoon. Students have one hour for lunch and two

20-minute breaks each day in the U. S. A.  One break is in the morning, and the other is in the afternoon.

In China, students have two hours' break during lunchtime and ten minutes' break for each class period.

In the U. S. A, students often go to the school cafeteria at lunchtime or at break. They buy snacks and

drinks there. The most popular after-school activities are baseball, football and basketball.
