In only two decades Asian Americans have become the fastest-growing U.S. minority. As their children began moving up through the nation's schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation's best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promises of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree. Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education. Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

单选题 While making tremendous achievements at college, Asian-American students _____.

单选题 What are the major factors that determine the success of Asian Americans?

【正确答案】 D

【答案解析】解析：事实细节题。文章第2段第1句说明了第一个原因是American educational system，最后一句说明了第二个原因为Asian culture，即选项D。选项A中的solid foundation in basic mathematics在文章第1段提到，但这只是亚裔美国学生偏爱数学和理工科的部分原因，选项B和C无原文依据，且选项C后半部分也不合情理。

单选题 Few Asian-American students major in human sciences mainly because _____.

单选题 Why do the two "explanations" (Line 1, Para. 3) worry Asian Americans?

【正确答案】 A

【答案解析】解析：推理判断题。本题考查因果关系。本题仍然是针对最后一段的首句，because of指出了原因，结合下一句的social isolation等词，可以推断亚裔美国人担心自己的种族形象太突出，最终被社会所孤立，由此可见，A为正确选项。本题最具干扰性的是选项D，该选项中的character与原文的racial image意思相近，但与其说选项D是亚裔美国人担心的问题，不如说这是本土美国人应该担心的问题。
