46、根据第二段中的“But when the same humans walked.dived at their enemies”和最后一段中的“Crows also recognize people who are kind to them”可知,乌鸦很聪明也善于观察;再根据第三段中的“At first,only the banded birds.more and more crows joined in”可知,乌鸦是群体性的动物,社交性较强。11.D解析 细节理解题。根据第四段中的“the scientists found that.a different part of its brain
47、lit up”可知,乌鸦在面对不同任务时,大脑的不同区域在起作用。【破解长难句】Then he worked with scientists at the university who scan animal brains to see which parts of a crows brain do certain tasks.【分析】本句为复合句,who scan animal brains 为定语从句;动词不定式to see 作目的状语;which parts of a crows brain do certain tasks为宾语从句,作see的宾语。【译文】然后,他与大学里的科学家们一
48、起工作,科学家们扫描乌鸦的大脑,看看乌鸦大脑的哪些部分可以完成特定的任务。【语篇导读】本文是议论文。文章讨论了人们是否应该担心塑料微粒可能对健康产生影响,作者通过两位教授的观点论证了人们目前没有必要害怕,但是为了环境我们可以选择尽量少用塑料制品。12.A解析 细节理解题。根据第一段第一句和第二段最后一句可知,塑料制品在被加热时会释放塑料微粒,所以温度是塑料微粒释放的因素。13.B解析 词义猜测题。根据第一段中的“We still dont have enough evidence.by infants or adults”以及第二段中的“The last thing we want to do
49、”可知,我们还没有找到足够的证据证明塑料微粒会对婴儿或成人的健康造成威胁,所以此处表示我们最不想做的事情是让父母过度担心。14.B解析 推理判断题。根据第三段中的“Schwabl,another professor.higher temperatures”可知,他认为有必要进行更多的相关研究,可见他非常关心塑料微粒问题。15.D解析 推理判断题。文章第一段引出是否应该担心塑料微粒的问题,接着第二段谈到教授John Boland的建议及一些研究人员的结论,第三段提到另一个教授Schwabl的看法和一些研究结论,故本篇文章主要是通过对比研究结论来展开的。.【语篇导读】本文是说明文。在高中培养很强的
