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.

A.sponsored
B.recommended
C.criticized
D.supervised
参考答案:D
解析:
[试题考点] 上下文语意关系和动词词义辨析。
[解题思路] 本题空格位于句子的谓语部分,其宾语为project,该句的大意为“Terrie Moffitt ______了一项衡量先天因素和后天培养相对重要性的项目”,前文指出Terrie Moffitt是one of them,即one of some wiser practitioners,而后文中更提到了Dr. Moffitt’s team,这些都表明他参与了这一项目,将各个选项代入文中,只有选项[D]supervised“指导;监督;主管”可以表明这一情况,代入文中意为“负责该项目”。
[干扰排除] 选项[A]sponsored意为“资助;赞助”,选项[B]recommended意为“推荐;介绍”,选项[C]criticized意为“批评;批判”,由于下文表明Terrie Moffitt参与了该项目,而“赞助”、“推荐”或者“批评”该项目都没有参与其中进行研究的意思,故均可排除。
