问题 单项选择题

针对网络聊天者的调查显示,存在不良企图网络聊天者占被调查对象的51%。同时发现,有半数以上的网络聊天者同时是精神空虚者。而精神空虚者大多有吸烟、酗酒等不良行为。由此可见()。

A.网络聊天者中可能没有精神空虚者

B.存在不良企图网络聊天者中一定有吸烟者

C.存在不良企图网络聊天者中一定有酗酒者

D.存在不良企图网络聊天者中一定有精神空虚者

答案

参考答案:D

解析:

根据题干意思结合选项,A与题干不符合,排除掉;B、C也是不能从题干推理出来的,排除掉。既然半数以上网络聊天者同时精神空虚,而存有不良企图的聊天者占5l%,那么显然二者有重合部分,所以选择D。

     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 achievements are made 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 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 treatment in areas like mathematics

and science because they will be judged more objectively (客观). And the money spent on education is more

immediately returned 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 should 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, such as family value, the

importance of education and so on that lead to their success.

     Both explanations for academic success worry Asian Americans because of fears that they could cause

the native Americans' unhappiness. Many can remember when Chinese, Japanese and Filipino immigrants (移

民) were unequally treated because of social separation. Indeed, it was not until 1952 that laws were laid down

giving all Asian immigrants the right to citizenship.

3. While making great achievements at college, Asian-American students _____.

A. are afraid that their.academic successes take on a strong Asian character
