Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.

But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.

Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.

“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”

2.What does Professor Paul Davies believe? (2’) (No more than 6 words)

Many scientists have believed that there may be a _________of life on the Mar．

高三英语单项填空简单题查看答案及解析

Believe it or not but it is true. There are people who lose the ability to understand or use words due to brain damage. But they become extremely good at something else. They become experts at spotting liars. The condition in which people lose their power to understand or use words due to brain damage are called aphasia(失语症). A study conducted in Massachusetts, U.S., has clearly proved that aphasics make good lie detectors(测谎仪).

In the last 100 years, many doctors studying the brain have mentioned examples of this amazing power of patients suffering from aphasia. Recently, scientists conducted tests to see if all that was said about aphasics was true. They studied the powers of a mixed group of people. Some were normal; others were aphasic. And it was proved clearly that the normal volunteers still got fooled by words. The aphasics were far ahead of them in recognizing false speech. The results of the study were reported in the magazine Nature.

`Fourteen years ago, famous American doctor, Dr. Oliver Sacks, wrote about his experiences with aphasic patients in a book. He remembered a particular incident in a hospital. Patients from the aphasia room were watching TV. Their president, Ronald Reagan, was giving a speech. He was trying to put feelings into each and every word of his speech. But his speech had an opposite effect on the patients. They were not impressed. On the contrary, the whole room shook with their laughter. The aphasics knew that he did not mean a word of what he was saying.

Dr. Sacks saw aphasics as more gifted than normal people. Normal people “get carried away” by words. An aphasic cannot understand words. But he or she can still understand what is being said. He said most of the aphasics had this superior understanding. So, while normal people think of aphasic patients as brain damaged, they actually seem to understand human expressions better.

1.We can know from the first paragraph ___.

A. how aphasics get their special ability　　 B. that aphasics can tell if you are lying

C. that aphasics are good at telling lies　　 D. why aphasics are experts at spotting liars

2.The phrase “get carried away” in the last paragraph means ___.

A. get misunderstood　　 B. get excited　　 C. get fooled　　 D. get discouraged

3.Dr. Oliver Sacks thinks that aphasics ___.

A. can be cured totally　　 B. can not understand what is being said

C. are specially gifted in a way　　 D. should be treated equally and nicely

4.Which would be the best title of the passage?

A. A great discovery　　 B. A special way of understanding

C. Why aphasics can’t talk　　 D. The great lie detectors

Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets (彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash there that scientists are now concerned that if we don't clean it up, we may all be in mortal（致命的）danger.

The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning things that no longer served any useful purpose in space.

It is estimated that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.

The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft. Moreover, pieces of junk may collide with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

1.What was the first piece of man-made space trash ?

A. A camera.　　 B. A tool kit.

C. A fuel tank.　　 D. A broken satellite.

2.Why were scientists NOT concerned about space trash in the beginning ?

A. It no longer served any useful purpose.

B. It was millions of miles away from the Earth.

C. It did not cause any problems.

D. It was regarded as similar to comets and stars.

3.Which of the following statements is true about space junk ?

A. It is huge, heavy machines.

B. It never changes position.

C. It floats slowly around the Earth.

D. It may cause problems for space shuttles.

4.What has been done about the space trash problem ?

A. Scientists have cleaned up most of the trash.

B. Large pieces of space trash are being closely watched.

C. Many nations have worked together to stop polluting space.

D. Ground stations are built to help store the trash properly in space.
