according to the investigation of the income sources of students, the income of american and chinese students comes from parents, part-time job and scholarship, however, the percentage of each income is quite different, fifty percent of the american students income comes from their parents, fifteen percent comes from the scholarships granted by colleges and universities and the rest comes from part-time jobs. ninety percent of chinese students' income comes from their parents.

　　in my opinion, the main reasons for the difference is that american students are taught to be independent when they are very young, while chinese students are taken such good care of that it is very difficult for them to live on their own. what's more, chinese students have fewer opportunities to find part-time jobs.

　　nowadays more and more chinese students are seeking part-time jobs. for one thing, some students come from poor areast and their parents can't afford the high cost of education. for another, they're eager to acquire some social skills and earn some money which will help them do more in school and live independently, as far as american students are concerned, i think the sources of american students' income will remain the same.
