求英语作文,后天就要!Topic：The performance of chinese and american stu

Many of us are aware of the better performance of the chinese students on their studies as compared with the american students. However, do you know what are the reasons behind this?
Yes, to have performed well in the studies, the most important thing is to put in more effort. But still why will these chinese students had the adamant to work so hard? It is the strong belief in hard work. This is a morality that had been passed down for many generations in the chinese society. There is an ancient saying: "As you sow, so shall you reap." You will get the pay from your deeds no matter fast or slow. This belief had rooted in the mind of all the chinese as if they are born to be hardworking although there are still some exceptions which the amount is negligible.
There is also another cause that force the chinese students to be more hardworking, that is the strong duty to their families. People in china unlike america, are only allowed to have one kid in every family. This leads to a heavier burden on the shoulders of the children. These responsibilities will cause them to work harder and harder and harder in order not to disappoint their parents and for a better life in future.
