Each year, thousands of Chinese middle school students go to study in foreign countries. Recent research shows among 428 middle school students in Shanghai, nearly half of them would like to study abroad(国外). "Chinese children are eager to go abroad to get a wider view, less academic (学业) competition or even family honour," said Chen Yi, a Chinese writer who has lived in the USA for 16 years. "But life in foreign countries can be hard for young people."

　　"We have to face the culture shock(差异) and language problems," said Hong Guang, a Chinese student in London. However, these are not always the most difficult things to overcome. To most children, controlling themselves when studying alone in a foreign country is a big challenge.

　　Zhang Jia, a 16-year-old student from Shanghai, entered high school in Melbourne, Australia last October. To his surprise, his teachers there seldom pushed students to study. And usually there wasn't much homework. Some of his friends spent their whole year's money in the first two months of the new term.

　　"Studying abroad at a young age can help students learn foreign languages quickly and broaden their minds, but students and parents should know about the challenges," Chen said.
