A
1. B。文章的第一段就指出,当你睡不着觉时,“Maybe next you should try cooling your brain”;接下来文章进一步介绍了“cooling your brain”这一治疗失眠症的方法,所以答案为B。
2. D。第二段最后讲到“cooling the brain can reduce the amount of time it takes people with insomnia to fall asleep – and increase the length of time they stay that way”,所以答案选D。
3. C。第四段具体讲解了科学家的实验。由该段最后一句话“This is similar to the sleep enjoyed by healthy study subjects who didn’t have insomnia… ”可知,戴上了cooling cap之后有失眠症的病人和健康人的睡眠质量差不多,故选C项。
4. D。文章最后一句话说“We believe this has far-reaching implications for how insomnia can be managed in the future”. 其中“far-reaching implications”意思是“深远的含意”。所以,科学家认为cooling cap的发明为彻底治愈失眠症铺平了道路,奠定了基础。所以选D。C项干扰性比较强,文章最后一段中科学家肯定了冷却帽的优势,相信冷却帽在将来可能能被用于治疗失眠症,但是并没有明确表示冷却帽将被广泛使用,故C项推测过于绝对。
B
5. A。“the technology”指代的是前文的内容。文章第一句说“A team led by Professor Theodore Berger, from University of Southern California, can now manipulate brain cells in rats… ”,所以答案选A。
6. D。文章的第二到第四段详细讲了科学家的实验。第二段说“In the study, researchers first trained rats to remember which of two levers they pressed first, then to press the other lever”。所以第一步是e,排除A、B选项。再观察C、D选项,它们不同的是b和d的顺序。文章第五段详细讲解了最后两步的顺序。应该先b然后d。所以答案选D。
7. B。根据文章第四段第一句话可知答案选B。
8. C。根据文章最后一段话“We have very many steps to go before this can be achieved”可推知答案为C。
C
9. B。文章首段就已经点明主旨。根据“Striking new images from mountains of Mars may be the best evidence yet of the existence of flowing liquid water on the planet… ”可以推测出答案为B。
10. C。根据文章第四段最后一句话可知研究人员认为这些水痕是由冻土融化而来,所以答案为C。由第四段第一句中的“They spread on hillsides warmed by the summer sun”和“but when winter returns, the trails fade away”可知这些水痕在夏天出现,冬天开始慢慢消失,所以A项的“only seen in summer”不对。
11. A。根据文章第七段中的“The presence of salt lowers the temperature at which water freezes… ”可知正确答案为A。
12. C。第九段的this是与上一段的内容相呼应。第八段Lewis Dartnell说,“So perhaps there could be hardy microbes surviving in these short period of summer meltwater on the desert surface of Mars”, 所以答案选C。
D
13. C。本文主旨句是第二段第一句话,下文都在围绕这句话展开,所以答案为C。
14. B。由前面一句话“But after reviewing over 40 studies, Morgan and Kathryn Rose... argue that there is no evidence to support this”可知,这两个研究人员不相信有关基因的解释。所以后面的debunk the idea意思就是“show the falseness of (something)”,故选B。
15. D。根据第三段首句“And it looks as if those lifestyle changes are beginning to be felt in some western countries too”可知,这从侧面反映了上文提到的是生活方式的变化,所以选D。
16. D。根据文章倒数第二段最后一句话可推知答案为D。
E
17. C。通观全文,文章列举了四种最易对青少年产生危害的情况,并提出了具体的防护措施。所以选C。
18. D。第三段提到了“To keep kids safe, AAP recommends widow guards be installed on second story and higher windows”,所以选D。
19. A。第四段提到,“A recent study in Seattle, Washington showed that helmets reduced the risk of head injury by 85 percent and brain injury by 88 percent”。后面紧接着说家长要买符合标准要求的头盔。所以答案选A。
20. C。第二段最后一句话指出“but their effectiveness is increased dreamtically when sued in combination with on another”,所以答案选C。
