题目内容
19.Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.It is caused mainly by industrial underwater explosions,ocean drilling,and ship engines.Some scientists have proposed (提议) setting a noise limit of one hundred and twenty decibels (分贝) in oceans.They have observed that noises at the level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals.They found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales'ability to exchange information and find their way.Some of the whales even died.
Some researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels.They say such a limit would mean an end to important industrial and scientific research.Scientists do not know how much and what kinds of noises are harmful to ocean animals.However,many scientists agree that noise is a greater danger than they believed.They want to prevent noises from harming creatures (生物) in the ocean.
29.Concerning the effect of noises on whales,which of the following is TRUE?B
A.They are deaf to noises.
B.Noises at a certain level may hurt them.
C.Noises could kill them.
D.Noises will cause them to lose their eyesight.
30.Some scientists think that the noise limit of one hundred and twenty decibels wouldA.
A.prevent them doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output
31.According to the last paragraph,what will scientists most probably do in the future?D
A.They will study the effect of different noises in the sea.
B.They will work hard to make no noise.
C.They will never do any scientific research in the sea.
D.They will protect sea animals from harmful noises.
分析 科学家认为,人类海上活动导致的噪音污染对海洋生物的健康和行为产生了巨大的影响,甚至威胁到了他们的生存.虽然科学家不知道什么样的噪音对海洋生物有害,然而许多科学家怀疑噪声的危害要远远大于他们想象的程度,因此他们要努力去防止噪声对于海洋动物的危害.
解答 29--31 BAD
29.B 推理判断题.根据第三段They found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales'ability to exchange information and find their way可知,这些海洋噪音影响到了鲸鱼的听力和导航能力,即:一定程度的噪音可能伤害鲸鱼.故选B.
30.A 细节理解题.根据四段They say such a limit would mean an end to important industrial and scientific research.可知,科学家们认为对于分贝的控制会影响一些工业和科学研究工作,所以A选项正确.
31.D 细节理解题:从最后一段的句子:They want to prevent noises from harming creatures in the ocean.可知,他们想要阻止噪音对于海洋生物的危害.故选D.
