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

C.are measured differently

D.have the same effect on humans

2.As to(依据) the effects of noises on whales, which of the following statements is TRUE according to the passage?

A.They are deaf to noises.

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.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

  Thinking is something you choose to do as a fish chooses to live in water.To he human is to think.But thinking may come naturally without your knowing how you do it.Tbinking about thinking is the key to critical(判断性的)thinking.When you think critically,you take control of your thinking processes(过程).Otherwise,you might be controlled by the ideas of others.Indeed,critical thinking is at the heart of education.

  The word“critical”here has a special meaning.It does not mean taking one view a-gainst another view,as when someone criticizes another person for doing something wrong.The nature of critical thinking is thinking beyond the easily seen-be-yond the pictures on TV,the untrue reports in the newspapers,and the faulty reasoning.

  Critical thinking is an attitude as much as an activity.If you are curious about life and desire to dig deeper into it,you are a critical thinker.If you find pleasure in deep thinking about different ideas,characters,and facts,you are a critical thinker.

  Activities of the mind and higher-order reasoning are processes of deep and careful consideration.They take time,and do not go hand in hand with the fast speed in to-day's world:fast foods,instant coffee,and self-developing film.If you are among the people who believe that speed is a measure of intelligence(智力),you may learn some-thing new from a story about Albert Einstein.The first time Banesh Hoffman,a scien-tist,was to discuss his work with Albert Einstein,Hoffman was too nervous to speak.But Einstein immediatelyput Hoffman at ease by saying,“Please go slowly.I don't understand things quickly.”
