Many scientists are now exploring the idea of going to live on Mars. Some other scientists from the MASA AMES Center(美国宇航局) have already started the creation of a “Mars town” and many others are in fact already experimenting with it. Of course, these experiments are done on Earth itself but this “Mars town” has an environment practically like that of Mars.

The astronauts working in these towns wear their space suit and also do everything they would really have to carry out if they ever go to Mars in the future.

But Mars would be like Earth, a temporary（临时的） place for humans. When the Sun starts swallowing up(吞掉) the planets, Mars will disappear only hours after Earth. So Mars only seems to be the ideal place to spread the human beings. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster, I mean asteroids(小行星) hitting and things like that.

If we humans do not want to disappear when Earth or Mars gets swallowed up, we will have to go and live beyond the solar system. But are there any planets outside our solar system prepared to support life? Astronomers’ answer is:

“If Earth can support life, why can’t other planets do the same too? Astronomers have already discovered a Jupiter(木星)- like planet orbiting a Sun-like star, so why not an Earth-like planet orbiting a Sun-like star?

To achieve this goal though, many other problems have to be taken into consideration. How do we transform(改造) a dusty planet like Mars into one more or less like our Earth? How should we go on? There is still a long way to go.

1. The “Mars town” mentioned in the passage is ___________

2. We can know from the passage that astronomers probably think ____________

3.Why would Mars only be a temporary(临时) place for humans?

4.The underlined word “orbiting” in the fifth paragraph is closest in meaning to “________”

5.Which of the following would be the best title for this passage?

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).

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 (被感染的).

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, Which of the following is increasingly dangerous to sea creatures?

A. The sound of cars. 　　　　　　　　　　　 B. The sound of voices.

C. Man-made 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

D. 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 right unit (单位) for measuring underwater noise.

D. Different ocean animals may have different reactions to noises.

4.What can we learn about the whales from the passage?

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.
