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 to gether 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.

选项
A、about
B、to
C、from
D、like
答案
B
解析
考查介词辨析。本句的后半句出现了比较级,可见是和前文形成比较关系,因此和上半句介词保持一致,故用介词to。本句意为“它(这种相似性)吸引我们到相同的环境,并且使我们更为相似”。因此答案为to。
