9、e pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, under

10、water earthquakes, and sounds made by animals themselves. Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninetyfive would have the same effect. Some

11、scientists have proposed setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team

12、 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. The explosions had caused their ears to bleed and become infected. Many researchers w

13、hose 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 suspect tha

14、t noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean. 16According to the passage, which of the following is increasingly dangerous to sea creatures?AThe sound of cars.BThe sound of voices.CManmade noise pollution.DThe sound of steps.17Accord

15、ing to the passage, natural sounds include all of the following EXCEPT_Asounds made by animals themselvesBocean drillingCunderwater earthquakesDthe breaking of ice fields18Which of the following is discussed in the third paragraph?AThe same noise level produces a different effect on land and in the

16、ocean.BDifferent places may have different types of noises.CThe decibel is not a suitable unit for measuring underwater noise.DDifferent ocean animals may have different reactions to noises.19Which of the following is true of whales?AThey wont be confused by noises.BThey are deaf to noises.CTheir ab

17、ility to reproduce will be lowered by highlevel noises.DTheir hearing will be damaged by highlevel noises.20According to the passage, what will scientists most probably do in the future?AThey will work hard to reduce ocean noise pollution.BThey will protect animals from harmful noises.CThey will try

18、 to set a limit of 120 decibels.DThey will study the effect of ocean noise pollution.BThe sea has always interested man. From it we can get food, minerals, and treasure. For thousands of years, we could sail on it. But we could not go far beneath its surface. Man wants to explore deep into the sea.

19、However，we are not fish. We must breathe air, so we cant stay under the waters surface for any length of time. To explore deep water, man faces even more dangers and problems. A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wea

20、r a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure. When a diver is under great pressu

21、re, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double up in pain. They can even kill him.21O

26、有面额再小一点的零钱。6C根据下文as I held it out to her判断“我把钱放到手里”恰当。7D她刚才与我说话，这时又去与另外一个顾客交谈，所以“转向”恰当。8C售货员只是瞅了我一眼，却不搭理我，转向了另外一个顾客，所以认为是“粗鲁的”。9B前面提到孩子刚刚学走路，所以个头应该不高，因此我想安慰他，需要弯下腰。10A孩子没有得到他想要的东西，很明显他开始哭泣了。11A我想离开，这时一位老妇人拦住我，可判断touched贴切。12C孩子没有得到他想要的东西，开始哭泣了，可判断upset贴切。13D根据下文the car only cost 50p to her可判断bought恰

27、当。14A孩子想要的玩具到手了，所以立即停止了哭泣。15B老人的善良打动了我，所以哭了，说不出话来。.A研究表明，噪音污染危及了海洋生物的生存。科学家将来要采取措施拯救海洋生物，阻止噪音对海洋生物的伤害。16C细节理解题。由第一段Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.可知，噪音污染危及了海洋生物的生存。17B细节理解题。由第二段These sounds include the breaking of

28、ice fields, underwater earthquakes, and sounds made by animals themselves.可知，ocean drilling不是自然的声音。18A19D推理判断题。由第六段The research team found that powerful underwater explosions were causing whales in the area to lose their hearing.可知，水下巨大的爆炸声会使鲸失去听力。20B推理判断题。由文章的最后一句话They want to prevent noises from h

29、arming creatures in the ocean.可知，科学家将来要采取措施阻止噪音对海洋生物的伤害。B自古以来，海底丰富的资源一直吸引着人类。然而，从事深水潜水探索却不是一件轻松的工作。本文向我们介绍的就是深水潜水员所面临的困难和挑战。21B主旨大意题。由文章结构可以看出，文章首先点明了海洋对我们人类的重大意义，然后提出了文章要说明的主题：To explore deep water, man faces even more dangers and problems.下文围绕这一主题作了详细的说明。22A23A推理判断题。潜水员在深水里要承受巨大的压力，浮到水面时，水压骤减，这对人体来说是很大的挑战。由此可以推断从事深水潜水工作的人，身体应该健康(in good health)。24C细节理解题。由If the diver rises too quicklyThe diver is then suffering from the bends.可知，潜水员得bends的原因是在海水中上升得太快。25B推理判断题。从文章内容可以知道，在深海潜水时，人会面临更大的危险和更多的麻烦(more dangers and problems)。由此可以判断，人在深海是很不舒适的。-
