求翻译：造成这样的原因不仅仅是家庭的原因，还有国家教育制度的原因，虽然我们比美国学生学习努力，但是都是书里的东西，对于社会贡献来说，完全可以忽略不计的是什么意思？

Caused by this reason is not just family reasons, as well as the national education system because, although we strive to students than the United States, but all the things the book, for contribution to society is completely negligible for

Creates such reason is not merely the family reason, but also has the country educational system reason, although we compare the American students to study diligently, but all is in the book thing, regarding the social contribution, definitely may ignore

Just cause such family reasons, there are reasons for the national education system, although we beat United States students studied hard, but are things in the book, for the Community contribution is entirely negligible
