Ocean Noise Pollution
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 which cause pain to human ears. In water, a decibel level of 195 would have the same effect as 120 decibels on land.
Some scientists have proposed setting a noise limit of 120 decibels in oceans. They have observed that noises at that level can frighten and confuse whales(鲸鱼).
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(出血)and become infected(感染).
Many researchers whose work depends on ocean sounds object to a limit of 120 decibels. They say such a limit is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
41. 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. Man-made noise pollution.
D. The sound of steps.
42. 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.
43. Which of the following is discussed in the third paragraph? ________
A. The same noise level produces a difference.
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.
44. 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.
45. 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.
