The Adjustment in Understanding of Man"s Relation to the Physical Universe
Nowadays the scattering of galaxies and the astounding abundance of stars are forcing those who ponder such matters to a further adjustment of their concept of the place and function of man in the material universe.
In the history of the51human mind， with its increasing knowledge of the surrounding context， there must have been a time when the philosophers of the52tribes began to realize that the world was not simply centered on man himself. The geocentric concept， which accepted a universe centered on the earth， then became common53
The second adjustment in the understanding of man"s relation to the physical universe was not generally acceptable54the sixteenth century. Copernican revolution soundly55the heliocentric Concept， the theory of a universe56on the sun. Man is a stubborn adherent to official dogma; eventually， however， he accepted the sun as the center.
Then， forty years ago， came the need for a third adjustment. This57has deeply exploded man"s pride and58， for it has carried with it the knowledge of the appalling number of galaxies.
The galactocentric universe59puts the earth and its life near the edge of one great galaxy in a universe of millions of galaxies. Man becomes peripheral among the billions of stars of his own Milky Way; and， according to the revelations of paleontology and geochemistry， he is60and apparently transient in the61of cosmic time.
The downgrading of the earth and sun and the elevation of the galaxies is not the end of this62of scientific pilgrims through philosophic fields. The need for another63adjustment now64not wholly unexpected by scientists，65wholly the result of one or two scientific revelations.
Our new problem concerns the spread of life throughout the universe. As unsolicited spokesmen for all the earthly organisms of land， sea， and air， we ask the thrilling question: Are we alone？

听力原文： You can tell the age of a tree by counting its tings. But these records of a tree's life really say a lot more. Scientists are using tree tings to learn what's been happening on the sun's surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows, it adds a layer to its trunk, taking up chemical elements from the air. By looking at the elements in the rings from a given year, scientists can tell what elements were in the air that year.
Dr. Stevenson is analyzing one element, carbon—14, in rings from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon--14 trail back in time, he found carbon—14 levels change with the intensity of solar burning. You see the sun has cycles. Sometimes it bums fiercely. At other times it's relatively calm. During the sun's violent periods, it throws off charged particles in fast moving streams, called solar winds. The particles interfere with the formation of carbon—14 on earth. When there is more solar wind activity, less carbon—14 is produced. Ten thousand years of tree rings show the carbon—14 level rises and falls about every four hundred and twenty years. The scientists concluded that solar wind activity must follow the same cycle.

A．To find out the origin of carbon- 14 on Earth.
B．To analyze the composition of different trees.
C．To look into the pattern of solar wind activity.
D．To examine the chemical elements in the Ice Age.
听力原文： Researchers do not know why people think some colours are warm and other colours are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colours remind people of warm days and cool colours remind them of cool days. Because in the north the sun is low during the winter, the sunlight appears quite blue. Because the sun is higher during the summer, the hot summer sunlight appears yellow.
People associate colours with different holidays. For example, red is associated with Valentine's Day. On February 14th, Americans send red hearts to people they love. People associate orange with Halloween in October and Thanksgiving Day in November. On October 31 st, many Americans put large orange pumpkins in their windows for Halloween. Many people wear green on St. Patrick's Day, March 17th. Violet is a dignified colour which is associated with Easter. On Easter Sunday, people decorate baskets with purple ribbons.
Many expressions in English use colours. These expressions show how people feel about the colours. For example, people associate red with a strong feeling like anger. When someone is very angry, people say that he or she sees red. Red is an active colour. A red-letter day is a lucky day. When criminals are caught in the middle of a crime, people say that they are caught red-handed. Green is the colour of grass and leaves. When someone grows plants well, people say he or she has green fingers. Blue is a sad, thoughtful colour. When someone is very sad, people say he or she is feeling blue. Blues is a kind of jazz that is usually very sad and slow.
(33)
A．A warm colour is a colour that is often used in restaurants.
B．A warm colour is a colour that gives off heat.
C．A warm colour is a colour near the red end of the light spectrum.
D．A warm colour is a colour that makes people feel upset.
That is just one of the newer gimmicks that make the modem car so much more comfortable to drive than those produced not so long ago. Another innovation is the self-adjusting seat. When you put the key in the car door, the front seat will automatically adjust itself to the driver's preferred driving position.
These ideas were dreamt up at General Motors' research laboratories in Detroit. The laboratory was set up in the mid-sixties, in response to consumer groups who attacked the company for its safety record. Since then, the company has set itself an impossible goal: that you'll be able to walk away from most car accidents. It spends roughly one billion US dollars every year on safety research.
The company is working on helping drivers survive crashes at higher speeds. The idea is that the driver won't fly out of the car because of his seat belt, He won't be crushed by the side door coming in because it will be strengthened by a side beam. His ribs won't be crushed, nor his organs injured by the steering wheel, because it will bend when the body hits it. His face won't be slashed by broken glass because the windscreen won't shatter.
Every year, the total world-wide bill for injuries of all types is estimated at US $ 500 billion. Transport injuries of all sorts account for one quarter of this. This gives some indication of the size of the problem the scientists working at General Motors' research laboratory have set themselves.
"Not any more." in paragraph one indicates that ______.
A．the sun is no longer as hot these days
B．the car's air-conditioner can make the interior cooler
C．the painful experience doesn't exist any longer
D．the driver doesn't need to wait before he gets in the ear now
Passage Two:Questions 26 to 30 are based on the following passage.A breakthrough (突破) in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if a modest increase could be provided in the EEC’s research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC’s scientific laboratories at Ispra, near Milan.
The senior West German scientist in charge of the Community’s solar energy programme, Mr. Joachim Gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the Community’s energy requirements even after the year 2000. But he said that with a modest increase in the present＜ sums, devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade.
Mr. Gretz calculates that if solar energy only provided three per cent of the EEC’s needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. And he believes that with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Community’s future energy needs.
At present the EEC spends about $2.6 millions a year on solar research at Ispra, one of the EEC’s official joint research centres, and another $3 millions a year in indirect research with universities and other independent bodies.
第26题：The phrase “be brought forward” (Line 2, Para. 1) most probably means ________.

B) be completed
C) be advanced
D) be introduced
听力原文： One of the most famous travelers in all of history was Marco Polo. At the age of 17, he left Italy with his father and uncle. It took them more than 3 years to cross the mountains and deserts of Asia. In the year 1275, they reached China. They stayed in China for almost 20 years, as guests of the emperor. He sent them on many trips around his empire. They found China far more advanced than Italy or any other countries in Europe.
After he returned to Italy, Marco Polo dictated many of his stories to a friend. His book, Description of the World, became the most popular book in Europe. People found it difficult to believe his stories of people, animals, places, and things. These are a few of his descriptions:
In one area of China, there were black stones. People dug them out of the mountains. They lit the black stones and they burned very slowly, giving off heat. The people used these stones to cook and to heat their homes.
In China there was a great system of highways. These highways had two lanes paved with stones or bricks. Men planted trees every ten feet to keep the sun off travelers' heads.
Most people believed Marco Polo' s stories. But others told him that they did not believe his descriptions. He answered that he did not tell half of what he saw.
Marco Polo came to China
A．alone.
B．with two friends.
C．with his brothers.
D．with his father and uncle.
Slowly through small loans for solar powered devices, microfinance is bringing light to these rural regions where a lack of electricity has stymied economic development, literacy rates and health.

“Earlier, they could not do much once the sun set. Now, the sun is used differently. They have increased their productivity, improved their health and socio-economic status,” said Pinal Shah from SEWA Bank, a micro -lending institution.
Vegetable seller Ramiben Waghri took out a loan to buy a solar lantern which she uses to light up her stall at night. The lantern costs between $66-$112, about a week？ s income for Waghri.
“The vegetables look better by this light, and it？ s cheaper than kerosene and doesn？ t smell,” said Waghri, who estimates she makes about 300 rupees ($6) more each evening with her lantern.
“If we can use the sun to save some money, why not？”
In India, solar power projects, often funded by micro credit institutions, are helping the country reduce carbon emissions and achieve its goal to double the contribution of renewable energy to 6%, or 25,000 megawatts, within the next four years.
Off-grid applications such as solar cookers and lanterns, which can provide several hours of light at night after being charged by the sun during the day, will help cut dependence on fossil fuels and reduce the fourth biggest emitter？ s carbon footprint, said Pradeep Dadhich, a senior fellow at energy research institute TERI.
“They are reaching people who otherwise have limited or no access to electricity, and depend on kerosene, diesel or firewood for their energy needs,” he said.“The applications not only satisfy these needs, they also improve the quality of life and reduce the carbon footprint.”
SEWA or Self Employed Women？ s Association, is among a growing number of microfinance institutions in India focused on providing affordable renewable energy sources to poor people, who otherwise would have had to stand for hours to buy kerosene for lamps, or trudge miles to collect firewood for cooking.
SKS Microfinance, India？ s largest MFI, offers solar lamps to its 5 million customers, while Grameen Surya Bijlee (Rural Solar Electricity) Foundation helps fund lamps and home and street lighting systems for villagers in India, Nepal and Bangladesh.
The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside？ I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.
