| Some scientists say that animals in the ocean are increasingly threatened by noise 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, underwater 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 scientists have proposed setting a noise limit of one hundred and twenty decibels in 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 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 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 suspect that noise is a greater danger than they believed.They want to prevent noises from harming creatures in the ocean. 1. According to the passage, which of the following is increasingly dangerous to sea creatures? A. The sound of a car. B. The sound of voices. C. Manmade noise pollution. D. The sound of steps. 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 C. the breaking of ice fields 3. Which of the following is discussed in the third paragraph? A. The same noise level produces a different effect on land and in the ocean. B. Different places may have different types of noises. C. The decibel is not a suitable unit for measuring underwater noise. D. Different ocean animals may have different reactions to noises. 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. |

| The sea has always interested man.From it he can get food, minerals, and treasure.For thousands of years, he could sail on it.But he could not go far beneath its surface. Man wants to explore deep into the sea.However, he is not a fish.He must breathe air, so he can't stay under the water's 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 wear 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 pressure, 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. 1. On the whole, this passage is about ________. A. special mixtures of gases in deep sea B. the problems man faces in deepsea diving C. air pressure under the surface of sea water D. a kind of illness that man suffers in the sea 2. A diver's body in deep water ________. A. is under great pressure B. is just like that of a fish C. suffers from the bends D. weighs very little 3. The passage does not say so, but it makes you think that ________. A. deepdivers should be in good health B. divers explore the deep sea only for treasure C. diving under the water too quickly causes a kind of illness D. there is a special mixture of gases under the sea 4. From the passage we can see that ________. A. the sea began to interest man a few years ago B. man is not at home deep in the sea C. all divers will get the bends sooner or later D. the air in the sea water will kill a diver if he is not careful |
