问题 　　Sexual selection, a mechanism of evolution that can drive the appearance of bright feathers and elaborate horns, is often assumed to operate largely among males.【B1】________a fresh look at the data suggests it is more widespread among females than many researchers【B2】________
　　It was Charles Darwin who【B3】________suggested that males often compete【B4】________other males for females to mate with-which he argued could help explain why, for instance, some male birds have【B5】________bright plumage【B6】________this makes them a more obvious【B7】________for predators.
　　More recently, biologists have begun to realize that sexual selection【B8】________widely among females too, although Tim Janicke at the Centre for Functional and Evolutionary Ecology in France and his colleagues say it is still assumed to be a【B9】________peculiarity.
　　Now, Janicke and his colleagues have【B10】________evidence of female-orientated sexual selection in 72 species across the animal kingdom from scientific literature【B11】________between 2015 and 2020. They say the analysis suggests that【B12】________for mates in females should be considered the【B13】________
　　" We believe that our view of how we see sex differences in【B14】________, and also sexual selection in particular, is still very【B15】________towards males," says Janicke.
　　The analysis shows evidence of female sexual selection in a broad【B16】________of animals.【B17】________, in various species of pike, it is the female that is more colorful, with more【B18】________to attract mates. And in some tropical wading birds, such as jacanas, females fight each other【B19】________the attention of the highest quality male. The researchers invite investigators to spend more time studying such behavior in females.
　　" Sexual selection is a process that may【B20】________any sex," says Ingrid at Uppsala University in Sweden.
【B11】
选项 A、issued
B、published
C、publicized
D、distributed
答案[B]
解析 本题考查动词辨析。四个选项分别为[A]issued“出版，发表，发行(多指通过官方或正式渠道正式发行)”；[B]published“出版，发行，发表(多指出版发行文字作品，也指发布新闻或发表见解等)”；[C]publicized“宣传，推广，宣扬，传播”；[D]distributed“分发，分配，分销，使散开，使分布(指把东西分发给所属者或应得者)”。根据句子意思可知这里应选“发表”之意，由于发表的是文字作品，故选用过去分词published，作scientific literature的后置定语。故选项[B]正确。
