问题     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、career-killing
B、career-facilitating
C、time-consuming
D、energy-saving

答案A

解析 本题的解答方式同题2。本题所在句子的大致意思为:DNA结构的共同发现者,James Watson,近来对上述第二个问题发表了些不智的评论,这种举动______。显然此处需要根据下文的意思推断出这种举动给James Watson造成了什么后果,由本段的最后一句的大致意思——JamesWatson被迫离开了实验室,可推断出此处填入的词所表达的意思要和最后一句意思相近,因此只有A选项意为:这种举动毁掉了他的事业,符合文意。
