Few scientific fields are as full of risk as that of research into human intelligence. The two questions that (1) over and over again are "is it a result of nature or nurture" and "does race make a difference"
Making (2) comments about the second question can be a (3) move, as James Watson, a co-discoverer of DNA structure, recently found. He suggested that he was " (4) about the prospect of Africa" (5) "all our social policies are based on the fact that their intelligence is the same as ours (white people) (6) all the testing says not really". Such (7) by Dr. Watson are not merely (8) , they are scientifically weird. If the term (9) has any useful scientific meaning, then Africa, the continent where modern humanity began, is most racially diverse. The resulting (10) among the public forced Dr. Watson to leave his laboratory.
(11) , the study of the first question (12) between intelligence and genetics— has some wiser practitioners. One of them, Terrie Moffitt, of King’s College, has just (13) a project judging the relative importance of nature and nurture. Dr. Moffitt’s team (14) the effect on intelligence of breastfeeding, but in a genetic context. Previous studies have shown that breastfed children are more intelligent, (15) about six IQ points, than those given baby formulas.
The team, however, (16) the involvement of a gene called FADS2, which comes in two varieties, known as C and G. The researchers (17) if these two varieties interacted differently with breast milk. (18) on data from two groups of people, they found that the intelligence increase associated with breastfeeding only happened to people having (19) at least one copy of the C variety. The effect did not. (20) on the social classes or IQs of the parents.
2（）
A.prompt
B.hasty
C.general
D.stupid
参考答案：D
解析：
[试题考点] 上下文语意关系和形容词词义辨析。
[解题思路] 本题空格所在句句意为“对于第二个问题做出______的评论将会是______的行为”。其中“第二个问题”指代上文中提到的“种族是否影响人的智力”。下文指出，James Watson认为非洲人的智力不如白人，紧接着作者评价这一说法在科学上是讲不通的(they are scientifically weird)。由此可知，空格处词语对comments的评价应与下文作者对James Watson观点的评价相符，四个选项中只有选项[D]stupid符合文意。
[干扰排除] 选项[A]prompt意为“及时的；迅速的”。选项[B]hasty意为“仓促的；匆忙的”，文中并没有说明James Watson下结论时是迅速的或仓促的，故可排除这两项。选项[C]general意为“一般的；普通的；大致的”，代入文中也不符合文意。另外，考生易将hasty理解为“轻率的；草率的”而误选，但hasty作此意讲时，多作表语，用于be hasty in doing sth的结构中，故排除。
