American high schools have a dropout rate (辍学率) of up to 50%. There are many reasons for students leaving school:

● For two thirds of the dropouts, motivation (动力) is the problem. They can’t just work hard enough.

● Almost half of them said that they had missed so many classes that they could not follow any more.

● Many said that they were not ready well enough in their earlier school.

● For a third of them, getting a job is more important than finishing school.

High school dropouts have more problems in their future lives. They are more likely to be out of work or live a poor life. There is also a big difference in income (收入) if you compare (比较) high school dropouts with graduates. A study shows Americans with a bachelor’s degree (学士学位) get about $50,000, those with a high school diploma about $28,000 and dropouts only about $20,000.

Many younger students do not understand the influence of dropping out of school. They often need better teachers, more lessons to get good grades in subjects and more help with learning problems. Some schools in America have changed this situation. Some schools offer evening classes or allow students to come back at a later age.
