In the last 500 years, nothing about people — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可树)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu¬rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo¬ple starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.
1. according to the passage, which of the following has changed the most in the last 500 years?
A. Food.     B. Clothing.          C. Ideology.           D. Language.
2. The word "some" in the last sentence of the first paragraph refers to________.
A. some cocoa trees                  B. some chocolate drinks.
C. some shops                          D. some South American Indians
3. Thousands of Irish people starved during the " Potato Famine" because________
A. they were so dependent on potatoes that they refused to eat anything else
B. they were forced to leave their homeland and move to America
C. the weather conditions in Ireland were not suitable for growing potatoes
D. the potato harvest was bad
4. according to the passage, which of the following statements is NOT true?
A. One third of the world’s population drinks coffee.
B. Coffee is native to Colombia.
C. Coffee can keep one awake.
D. Coffee drinks were first made by Arabs.
答案

举一反三
For nearly a century before there was such a thing as a space program,a view of space was possible.People could see full views of the Moon,explore Mars(探测火星),and study the outer space beauty.All of this was made possible by a small group of artist-astronomers(天文艺术家) who worked to show people how other worlds in space might look.
Lucien Rudaux,a French artist,was the first to use his artistic ability and his knowledge of astronomy in art.His paintings show a mixture of skilled observations,brilliant imagination and careful attention.As a result,many of his works have come surprisingly close to actual conditions on distant planets.His painting of Mars included moonlike craters(火山口) that were first photographed by the astronauts in 1965.His 1930 painting of a dust storm looks remarkably like a photograph of a storm taken by the astronauts in 1976.
The artist-astronomers,including Rudaux,made people interested in outer space by painting what turned out to be exact portraits of the planets.
小题1:The passage tells us _________.
A.the surprising exactness of space artistsB.the popular success of Lucien Rudaux

Animal Conservation
Many animal and plant species have become extinct(灭绝的)and many more are in critical danger. Finding ways to protect the earth"s wildlife and conserve(保护)the natural world they inhabit(居住)is now more important than ever.
Dodo
The Dodo is a classic example of how human caused damage to the earth"s biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island"s trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.
Rhinos
The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves(保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers(偷猎者).
The Giant Panda
The future of the World Wildlife Fund"s symbol is far from certain. As few as 1000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, The panda"s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animals continued existence.
Whales
The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world"s oceans have been declared whale sanctuaries(保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions(碰撞)with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
Tigers
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.
小题1:It implies that _______.
A.The Dodo lacked the ability to protect itself from other animals
B.Sailors to the Island of Mauritius lived mainly on the Dodo
C.The Dodo used to be a strong animal that liked fighting.
D.The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius
小题2:Which group of the following animals has already ceased to exist according to the text?
A.The Dodo, Rhino and Giant Panda.
B.The Rhino, Whale and South China Tiger.
C.The Rhino, Panda, Whale and Tiger.
D.The Dodo and the Bali, Javan, and Caspian tigers.
小题3:______ can serve as a cure for certain diseases.
A.The whale’s rich oil
B.The panda"s black and white patched coat
C.The Rhino horn and tigers’ bones and organs
D.The Dodo’s delicious meat
小题4:Which of the following statements is NOT true?
A.The number of South China tigers has reached crisis point.
B.Many animals are threatened with extinction as a result of human activity.
C.People hunt for the endangered animals for high profit.
D.The Whale is the representing mark for the World Wildlife Fund.

Have you ever dreamed of visiting a planet in the Milky Way (银河系)? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like a science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to the small, non-hibernating mammals (哺乳动物) like rats.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "It’s like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia.Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system. There is a challenge of designing a suitable protective shelter (栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.
小题1:According to the article, the hibernation research ______.
A.is just an ideaB.is always a science fiction
C.has already finished successfullyD.has made some progress
小题2:In a hibernating state, a person needs ______.
A.less sleep B.more foodC.less energyD.more movement
小题3: The first try of the hibernation technology _____ the six-person Human Outer Planets
Exploration Mission to Jupiter’s moon Callisto.
A.will beB.has been planned for
C.is certain to beD.may be
小题4:What is the best title of the article?
A.Hibernation Study For Space TravelB.Welcome To Our Space Travel
C.To Hibernate, To Live Longer D.Welcome To The Milky Way

A strong wind can be a dangerous thing — sometimes it is powerful enough to knock you off your feet. But to plants, the wind is a source of new life, carrying them or their spores (孢子) thousands of miles.
A NASA satellite called QuikSCAT has discovered highways of wind over the Earth"s oceans. Scientists believe these invisible roads may explain why many nonflowering plants, such as mosses (苔) and lichens (地衣), grow where they do.
The satellite is able to send microwaves (微波) from space to the surface of the ocean. The pattern of signals that come back shows which way the winds are blowing.
Using this data, the scientists studied a group of islands in the southern hemisphere (半球), near Antarctica.Winds tend to blow anticlockwise (逆时针) in this region, but there are lots of local differences.
When the researchers compared these local patterns to botanical (植物学) data, they found that the wind had an important effect on where species of mosses, lichens, and other nonflowering plants grow.
For example, Bouvet Island and Heard Island, share 30 per cent of their moss species, 29 per cent of liverworts (叶苔), and 32 per cent of lichens — even though they are 4,430 kilometers apart. In contrast, Gough Island and Bouvet Island, separated by just 1,860 kilometers of sea, share only 16 per cent of mosses and 17 per cent of liverworts. They have no lichens in common.
Ferns (蕨类植物) and flowering plants don"t travel as well in the wind, so they don"t show the same kinds of distribution (分布) patterns.
小题1:This story is about _____.
A.the discovery of wind highwaysB.how wind travels
C.how wind affects different plantsD.one function of the wind
小题2:The underlined word "data" in the fourth paragraph means _____.
A.signalB.patternC.informationD.research
小题3: Which of the following is wrong?
A.Bouvet Island, Heard Island and Gough Island are all in the southern hemisphere.
B.Winds in the researched area blow anti-clockwise.
C.The scientists shouldn"t base this research on how winds affect where ferns grow.
D.Without the discovery of QuikSCAT, the research wouldn"t have made sense.
小题4: Which of the following diagrams shows the correct position of the islands?

The earth"s biosphere (the surface layer of the planet and the surrounding atmosphere) provides the land, air, water, and energy necessary to sustain life. This life-support system is a complex, interdependent one in which energy from the sun is changed into food for humans. The entire system depends on the sun, reasonably moderate temperature, and enough supplies of oxygen, pure water, and fertile soil.
Since the earth"s creation millions of years ago, the ecosystem has worked as an interdependent system relatively undisturbed by outside forces. But recently, especially since the Industrial Revolution, human beings have begun to disturb the balance of nature. Natural resources have been severely depleted (消耗) (forests have been destroyed, fertile land worn away, water polluted, and minerals used up), and the life-support system of air, water, and land has been poisoned by a variety of waste products and chemicals.
The degree of these problems was noted in a report by the U.N. Developing Council on Environmental Quality. This report predicted that if present trends continue, the world will be more crowded and polluted and less stable ecologically and politically than the world we live in now.
The twin problems of resource shortages and pollution are caused by three social forces.  First, the tremendous increase in population growth constantly increases the demand for food, energy, and other products. As the current population continues to increase, the stress on an already overburdened environment will be increased.A second source of the problem is the concentration of people in urban areas, where the ecosystem simply cannot absorb their waste products. Finally, environmental problems are worsened as more and more nations move toward modem development: an increased reliance on modern technology. As these nations become more technological, they will consume more energy, deplete more natural resources, and create more waste products than the biosphere can absorb.
小题1:The life-support system is composed of _____.
A.air, water and landB.the earth, the sun and energy
C.food, land and energyD.food, energy and the sun
小题2:The life-support system _____.
A.change energy from the sun into food for humans
B.depends on the sun for enough supplies of air, water and land
C.exists in the surface layer of the earth and the surrounding atmosphere
D.is a complex but independent system
小题3:The life-support system has been badly damaged by _____.
A.natural forcesB.human activitiesC.social movements D.political changes
小题4:The passage mainly talks about _____.
A.the effects of Industrial Revolution on human beings
B.the importance of life-support system to human beings
C.the significance of balance of nature
D.the destruction of life-support system and its causes
