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】are not merely【8】, they are scientifically weird. If the term race has any useful scientific meaning, then Africa, the continent where modern【9】began, is most racially diverse. The resulting【10】forced Dr Watson to leave his laboratory.
【11】, the study of【12】between intelligence and genetics has some wiser practitioners. One of them, Terrie Moffitt, of King’s College, has just【13】a project【14】the relative importance of nature and nurture. Dr Moffitt’s team【15】the effect on intelligence of breastfeeding, but in a genetic context. Previous studies have shown that breastfed children are more intelligent,【16】about six IQ points, than those given baby formulas.
The team, however,【17】the involvement of a gene called FADS2, which comes in two varieties, known as C and G. The researchers【18】if these two varieties【19】differently with breast milk.【20】on data two groups of people, they found that the intelligence increase associated with breastfeeding only happened to people having inherited at least one copy of the C variety. The effect did not depend on the social classes or IQs of the parents.
选项
A、concluding
B、investigating
C、judging
D、emphasizing
答案
C
解析
空格所在句子的大致意思为:Terrie Moffitt指导了一个项目,______先天基因与后天环境相对重要性。此处所填入的谓语动词作project的宾语补足语,在语义上应符合文章主旨大意。文章主旨是讨论“智力是受自然环境还是养育环境的影响?”可见,对此问题还无定论,因此填入的动词应表明Terrie Moffitt对此进行研究而不应是说明研究结论,由此可判断出只有C选项最符合文意,是正确答案。
