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、questioned
B、wondered
C、noted
D、found
答案
B
解析
本句是带有一般疑问句的宾语从句(if these varieties...),所以引导宾语从句谓语动词需表达疑问的意思。虽然A选项和B选项都可以和其后的宾语从句搭配,但是一定要结合上句语义选出恰当的谓语动词。上句已提到“研究团队怀疑这其中有名为FADS2的基因的作用……”,这句衔接为“研究者想知道……”,是衔接顺畅,符合文意的表达,因此B选项为正确答案。
