When you walk along a street in a big city in the United States， you may see clocks in most stores. Radio announcers give the correct time during the day. People there think that it is important to know the time. Most Americans have watches. They want to do certain things at certain times. They do not want to be late. Not all people all over the world value time. Suppose you visit a certain country in South America. You would find that people living there do not like to rush. If you had an appointment（约会）with someone， he would probably be late. He would not care for arriving on time. In some countries in South America， even the radio programs may not begin right on time， nor do the radio announcers think it important to announce the right time. Many people regard a clock as a machine. It seems to them that a person who does everything on time is controlled（控制）by a machine. They do not want a clock or any machine to have that much power over their lives.

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 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.

Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.

A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which 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(感染的).

Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.

Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.

1.The second paragraph mainly tells us that the noises on land and in water       .

A．are both from human activities.

B．both do harm to sea animals

B．Noises at a certain level may hurt them.

C．They are easily confused by noises.

D．Noises will limit their ability to reproduce.

3.Many researchers think that the noise limit of 120 decibels would        .

A．protect whales from noises

B．benefit them a lot in their research work

C．do good to their health

D．increase industrial output

4.What will scientists most probably do in the future?

A．Count the number of sea animals.

B．Stop their research on the ocean.

C．Study the effect of different noises.

D．Protect sea creatures from harmful noises.
