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.

选项
A、collected
B、gathered
C、amassed
D、piled
答案
[A]
解析
本题考查动词辨析。四个选项分别为[A]collected“收集,采集,聚集,积累”;[B]gathered“聚集,集合,搜集,收集(情报)(指人或物或抽象事物都可用,侧重于围绕—个中心的集合、聚集)”;[C]amassed“(尤指大量)积累,积聚(着重大量地积聚,尤指对如金钱、珠宝等有价值东西的大量积聚)”;[D]piled“堆放,摞起,叠放(着重指比较整齐地把东西堆积在一起)”。根据后文“他们说,分析表明,在雌性中竞争配偶应被视为常态”,结合空格前后的意思和单词选项,空格处应填写单词的意思为“搜集”,即搜集相关证据进行分析。collect多用于指物,侧重有区别地作选择或有安排有计划地把零散物集中起来。故选项[A]正确。
