     "USA? Britain? Which country is better to study in?" We often hear such discussions. As China opens its

doors, studying abroad has become a dream for many Chinese students. They want to learn about the world.

     It's true that studying abroad can help students develop themselves. Language skills (技能) will improve

and it may be easier to find jobs.

     But there are problems that should be considered (考虑). Language is the first. Students must spend a lot

of time learning another language and getting used to a different culture.

     Students must also learn to live without parents' care and deal with all kinds of things they haven't had to

do before, like looking after themselves. There are reports about Chinese students abroad sinking into an ocean

of difficulties and giving up easily. When they have to take care of themselves, it is hard for students to study

well.

     Finally, studying abroad brings a heavy burden (负担) to the family. For most Chinese parents, the cost

of studying abroad is very high. But is it worth it?

     We know that there are many famous people who succeed in great things through their hard work in

China. Liu Xiang is a good example. Once an American teacher invited him there but he refused. He kept

training hard with his Chinese teacher. He surprised the world when he won a gold medal (金牌) at the Athens

Olympics. So when you wonder which country is better to study in,consider whether studying abroad is the

right choice (选择).
