Though not biologically related, friends are as "related" as fourth cousins, sharing about 1% of genes. That is【C1】______a study, published from the University of California and Yale University in the Proceedings of the National Academy of Sciences, has【C2】______.
The study is a genome-wide analysis conducted【C3】______1,932 unique subjects which【C4】______pairs of unrelated friends and unrelated strangers. The same people were used in both【C5】______.
While 1% may seem【C6】______, it is not so to a geneticist. As James Fowler, professor of medical genetics at UC San Diego, says, "Most people do not even【C7】______their fourth cousins but somehow manage to select as friends the people who【C8】______our kin."
The study【C9】______found that the genes for smell were something shared in friends but not genes for immunity. Why this similarity exists in smell genes is difficult to explain, for now.【C10】______, as the team suggests, it draws us to similar environments but there is more【C11】______it. There could be many mechanisms working together that【C12】______us in choosing genetically similar friends【C13】______"functional kinship" of being friends with【C14】______!
One of the remarkable findings of the study was that the similar genes seem to be evolving【C15】______than other genes. Studying this could help【C16】______why human evolution picked pace in the last 30,000 years, with social environment being a major【C17】______factor.
The findings do not simply corroborate people’ s【C18】______to befriend those of similar【C19】______backgrounds, say the researchers. Though all the subjects were drawn from a population of European extraction, care was taken to【C20】______that all subjects, friends and strangers, were taken from the same population.
【C17】
选项
A、unpredictable
B、contributory
C、controllable
D、disruptive
答案
B
解析
考查形容词辨析。此空需要填入一个形容词,表达社会环境对人类进步所起到的作用。help及pick pace这两个词表达的都是积极的含义,因此此处需要填入一个带有褒义色彩的词,因此排除unpredictable“不可预知的”和disruptive“破坏性的”。而controllable“可控的”与语意无关,因此正确答案为B.contributory“促进的”。
