Move Earth — it’s no science fiction

LONDON — Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.

This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.

The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.

“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.

Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）— by cooking us.

That’s why the group decided to try to save Earth.

The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.

There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.

What makes the scientists plan to move Earth?

A. A few comets are moving to the direction of Earth.

B. Earth’s working life is coming to an end soon.

C. Earth will become too hot for mankind to keep alive.

D. The moon is moving farther and farther away from Earth.

If the plan is successful, Earth will have a working life of ______years.

A.12 billion B.6 billion C.18 billion D.24 billion

What serious problems might the plan cause according to the passage?

A. The comet might hit Earth and man might lose the moon.

B. Earth might be moved too far away and man might be frozen to death.

C. The comet might hit Jupiter or Saturn and never return to Earth.

D. Earth’s working life might be greatly shortened.

What does the underlined word “compromise” mean?

A. provide B. benefit C. share D. endanger

Which of the following best shows how the plan would work?

That holiday morning I didn’t have to attend school. Usually, on holidays, Mother 36 me to sleep in. And I would certainly take full advantage of it. On this particular morning, ___37___,I felt like getting up early.

I stood by my window overlooking the ___38___, having nothing better to do. But as it turned out, I was soon to learn about something ___39___ in life.

As I watched several people go by, get into their cars and go off, I ___40___ an old man on a bicycle with a bucket on its ___41___ and a basket rags and bottles on its back-carriage. He ___42___ from one car to another, washing and cleaning them. From the water on the ground, it seemed that he had already ___43___ washing and cleaning about a dozen or more cars. He must have begun to work quite early in the morning.

Several thoughts ___44___my mind as I watched him work. He wasn’t well-dressed. He had on a pair of shorts and a(n) ___45___ T-shirt. The bicycle he rode was not by any means the kind modern ___46___would want to be seen riding on. But he seemed___47___ with life. There he was, working hard at his small business, ___48___ at passers-by and stopping to chat now and then ___49___ elderly men and women on their way to the market nearby.

There was a noticeable touch of___50___ in the way he seemed to be doing things— ___51___the windscreen (挡风玻璃), then standing back to admire it; scrubbing (擦净) the wheels and ___52___, standing back to see what they look like after the scrub.

It was a ___53___ to learn, I felt. At no age need one have to beg for a ___54___if one has good health and is willing to work hard. For a while I felt ___55__ of myself. Young as I am—just sixteen, and there was this old man who must have been usefully engaged perhaps before the sun appeared above the horizon.

第二部分阅读理解（共25小题。第一节每小题2分，第二节每小题1分；满分45分）

第一节阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。

A new study in West Africa shows how farm irrigation systems powered by the sun can produce more food and money for villagers. The study in Benin found that solar-powered pumps are effective in supplying water, especially during the long dry season.

Sub-Saharan Africa is the part of the world with the least food security. The United Nations Food and Agriculture Organization estimates that more than one billion of the world’s people faced hunger last year. Around two hundred sixty-five million of them live south of the Sahara Desert. Lack of rainfall is one of their main causes of food shortages.

Jennifer Burney from Stanford University in California led the study. The research team helped build three solar-powered irrigation systems in northern Benin.

The solar-powered irrigation systems produced an average of nearly two metric tons of vegetables per month.

They sold the surplus(过剩的) produce at local markets. The earnings greatly increased their ability to buy food during the dry season which can last six to nine months.

People in the two villages with the systems were able to eat three to five more serving of vegetables per day. But making the surplus available at markets also had a wider effect.

The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also increased, though not as much.

The researchers note that only four percent of the cropland in sub-Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene. And solar power is environmentally friendly.

1. People living in sub-Saharan Africa are short of food mainly because______.

A. it seldom rains there throughout the year B. there is little farmland in the area

C. people there lack experience in farming D. people know nothing about irrigation techniques

2. Which of the following is an advantage of Jennifer’s irrigation systems?

A. They are not affected by the weather.

B. They cost much less than traditional irrigation systems.

C. They have no bad effects on the environment.

D. They use less fuel than traditional irrigation systems.

3. We can learn from the last paragraph that______.

A. people in South Africa will soon be provided with enough food

B. the demand for fuels like gasoline will greatly decrease in Africa

C. people in sub-Saharan Africa don’t take agriculture seriously

D. it’s worthwhile to use the new irrigation systems on the while

4. People in the two villages owe all the following to Jennifer’s irrigation systems EXCEPT that ______.

A. they could buy more food during the dry season

B. they could eat more vegetables than usual every day

C. they could supply local markets with vegetables

D. they could provide people in other villages with food
