D.The sound of steps.‎ 答案:C 解析:由第一段可知,人类活动制造的噪音污染正日益对海洋生物产生危害。‎ ‎2.According to the passage,natural sounds include all of the following EXCEPT 　　　. ‎ A.sounds made by animals themselves ‎ B.ocean drilling C.underwater earthquakes ‎ D.the breaking of ice fields 答案:B 解析:由第二段可知,ocean drilling属于人类活动制造的噪音,而非natural sounds。‎ ‎3.Which of the following is true of whales?‎ A.They won’t be confused by noises.‎ B.They are deaf to noises.‎ C.Their ability to reproduce will be lowered by high-level noises.‎ D.Their hearing will be damaged by high-level noises.‎ 答案:D 解析:由第五段中的“...were causing whales in the area to lose their hearing.”可知,高分贝的声音会损伤鲸鱼的听力。‎ ‎4.According to the passage,what will scientists most probably do in the future?‎ A.They will work hard to reduce ocean noise pollution.‎ B.They will protect animals from harmful noises.‎ C.They will try to set a limit of 120 decibels.‎ D.They will study the effect of ocean noise pollution.‎ 答案:B 解析:由最后一段可知,科学家们想要努力保护海洋生物免受噪音的伤害。‎ 六、七选五阅读理解根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。‎ ‎(2017·北京高考)‎ Every animal sleeps,but the reason for this has remained foggy.When lab rats are not allowed to sleep,they die within a month.1.　　 ‎ One idea is that sleep helps us strengthen new memories.2.　　　We know that,while awake,fresh memories are recorded by reinforcing (加强)connections between brain cells,but the memory processes that take place while we sleep have been unclear. ‎ 由莲山课件提供http://www.5ykj.com/ 资源全部免费由莲山课件提供http://www.5ykj.com/ 资源全部免费 Support is growing for a theory that sleep evolved so that connections between neurons(神经元)in the brain can be weakened overnight,making room for fresh memories to form the next day.3.　　 ‎ Now we have the most direct evidence yet that he is right.4.　　　The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping. ‎ If Tononi’s theory is right,it would explain why,when we miss a night’s sleep,we find it harder the next day to concentrate and learn new information—our brains may have smaller room for new experiences.‎ Their research also suggests how we may build lasting memories over time even though the synapses become thinner.The team discovered that some synapses seem to be protected and stayed the same size.5.　　　 “You keep what matters,”Tononi says. ‎ A.We should also try to sleep well the night before.‎ B.It’s as if the brain is preserving its most important memories.‎ C.Similarly,when people go for a few days without sleeping,they get sick.‎ D.The processes take place to stop our brains becoming loaded with memories.‎ E.That’s why students do better in tests if they get a chance to sleep after learning.‎ F.“Sleep is the price we pay for learning,” says Giulio Tononi,who developed the idea.‎ G.Tononi’s team measured the size of these connections,or synapses,in the brains of 12 mice.‎ 答案:1~5 CEFGB 由莲山课件提供http://www.5ykj.com/ 资源全部免费查看更多
