in only two decades Asian Americans have become the fastest-growing US minority. As their children began
moving up through the nation's schools,it became clear that a new kind of culture was coming out.Their achievments have taken on a decidely Asian
character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promise of a good job after college.Asians feel there will be less unfair theatment in areas like mathematics and science because they will be judged more objectively.
And the money spent on education is more immediately returned in something like engineering than with an arts degree.

question:
Few Asian-Americans students major in human sciences mainly because:
A.their English is not good enough.
B.they are afraid they might meet with unfir judgement in these areas.
C.there is a wide difference between Asian and Western cultures
D.they know little about American cultures and Western cultures.

答案选B,根据原文哪里可以看出来?我先A.

who began their education abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English.这里的but的转折,坚实的数学基础和少的可怜的英语知识的强烈反差,给出两方面的对比,连接下文.(这句话只给出两个方面,让你在接下来的文中领会暗含的,在另一个学科上感觉担心不被客观对待.)(没有表示出说因为英语不好而影响他们的选择)
问题中的B.可以从这句话上看出来
Asians feel there will be less unfair theatment in areas like mathematics and science because they will be judged more objectively.
认为在数学科学方面会得到一个公平的客观的评价.
有一方面就有另一方面,(就是上面先给出的对比)他们感觉unfair.

A.their English is not good enough,so a few of thme ...从文章中根本看不出来,也找不到这个意思,只是你在看了两方面的对比后,有了这种想当然的概念,认为很少人选择这个就是因为英语不好,你自己得出来这样得结论.实际文中没有.
B选项可以很明显在文中找到.

我觉得这样的题做的时候不能带着个人的观点,因为某句话想当然就选哪个.
容易落入陷阱. 最好在文中找带有明显的原因的句子,有据可查的选项做答案
