阅读短文，根据要求完成下面各小题。

Each year, many Chinese people go abroad because of all kinds of reasons. They are becoming younger and younger year by year. Even some Chinese parents send their children to foreign countries when they are only in a middle school. They think their children can get a wider view, less academic(学业) competition or family honor. But life can be hard for young people there. At first, they have to face the culture differences and language problems. However, these are not always the most difficult things to overcome(克服). To most children, controlling(管理) themselves well is a big challenge when studying alone in a strange country.
