在调查校园生物中，以下同学的做法，正确的是（）

任务型阅读：根据短文内容，填写下列表格。

“   USA? England? Australia? Which country is better to study in?” As China opens its door, many Chinese students want to learn about the world. It's true that studying abroad(国外的) can help students develop themselves. Students' language skills will be improved and it may be easier for them to find a job.

   But there are problems that should be considered(考虑). Language is the first. Students must use a lot of time to learn another language and to get used to a different culture.

    Students must also learn to live without parents' care and deal with all kinds of things. When they have to take care of themselves, it is hard for the 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(值得)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.
