Like schools in China, American schools begin in September after a long summer vacation. The first term is from September to January and the second is from February to June. Usually American children begin to go to school when five years old. Most students are seventeen or eighteen years old when they finish high school.

But unlike middle school students in China, high school students in America take only four or five subjects each term. They usually go to the same classes every day and have homework for every class. After class they do all kinds of interesting things.

After high school, many students go to college. They may go to a small or a large one. They usually have to pay a lot for their higher education. So lots of students work after school to make money for their studies.
