高三英语单项填空中等难度题查看答案及解析

Some scientists say that animals in the oceans 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 ninety－five would have the same effect.

Some scientists have suggested 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(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 and become infected.

Many researchers whose work depends on ocean sounds are against 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 don't think 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, 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

2.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 high­level noises.

D．Their hearing will be damaged by high­level noises.

3.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 sea 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 crisis(危机) at Japan’s Fukushima Dai-Ichi nuclear(核) energy center caused by the terrible earthquake has raised questions about the future of the nuclear energy industry. Arjun Makhijani is president of the Institute for Energy and Environmental Research in the United States. He says the disaster(灾难)in Japan is historic.

This week, the chairman of America’s nuclear agency said there is little chance that harmful radiation(辐射) from Japan could reach the United States. Gregory also said America has a strong program in place to deal with earthquake threats. No new nuclear power centers have been built in the United States since nineteen seventy-nine. That was when America’s worst nuclear accident happened at the Three Mile Island center in Pennsylvania. The accident began to turn public opinion against nuclear energy. At present, about twenty percent of electricity in the United States comes from nuclear energy.

German Chancellor Angela Merkel said Germany would close seven nuclear power centers while energy policy is reconsidered. The European Union is planning to test all centers in its twenty-seven member nations.

Developing nations are less willing to slow nuclear expansion. China said it will continue with plans to build about twenty-five new nuclear reactors（反应堆）. And India, under a cooperation agreement with the United States, plans to spend billions on new centers in the coming years.

Nuclear reactors supply fourteen percent of global electricity. Nuclear energy is a clean resource, producing no carbon gases. But radioactive waste is a serious unresolved issue. So is the presence of nuclear power centers in earthquake areas like the one near Bushehr, Iran.

1..

We can learn from the text that America ________.

A. experienced a terrible nuclear accident 32 years ago

B. has a strong program to deal with radiation danger

C. depends heavily on nuclear energy to produce electricity

D. will check all the reactors before cooperating with India

2..

According to the text, which country will be most likely to have a similar disaster?

A. German.          B. Iran.            C. India.           D. China.

3..

How does the author seem to feel about the future of nuclear energy?

A. Satisfied.      B. Pleased.         C. Wordless.       D. Surprised.

4..

The best title of the text is ________.

A. Various Opinions on Japan’s Nuclear Disaster

B. Japan’s Disaster is Likely to Run out of Control

C. America Feels Great Concern for Japan’s Nuclear Crisis

D. Japan’s Disaster Throws Doubt on Nuclear Energy Industry
