On the contrary, it helps farmers and improves forest soils. This is the unorthodox view of a German soil scientist who has shown that burnt clearings in the Amazon, dating back more than 1,000 years, helped create patches of rich, fertile soil that farmers still benefit from today.Most rainforest soils are thin and poor because they lack minerals and because the heat and heavy rainfall destroy most organic matter in the soils within four years of it reaching theforest floor. This means topsoil contains few of the ingredients needed for long-term successful farming.But Bruno Glaser, a soil scientist of the University of Bayreuth, has studied unexpected patches of fertile soils in the central Amazon. These soils contain lots of organic matter.Unburnt vegetation rots quickly, but black carbon persists in the soil for many centuries. Radiocarbon dating shows that the charred wood in Terra Preta soils is typically more than 1,000 years old.Terra Preta soils turn up in large patches all over the Amazon, where they are highly prized by farmers. All the patches fall within 500 square kilometers in the central Amazon. Glaser says the widespread presence of pottery (陶器) confirms the soils human origins.The findings add weight to the theory that large areas of the Amazon have recovered so well from past periods of agricultural use that the regrowth has been mistaken by generations of biologists for “virgin forest.During the past decade, researchers have discovered hundreds of large earth works deep in the jungle. They are up to 20 meters high and cover up to a square kilometer. Glaser claims that these earth works, built between AD 400 and 1400, were at the heart of urban civilizations. Now it seems the richness of the Terra Preta soils may explain how such civilizations managed to feed themselves.11. We learn from the passage that the traditional view of slash-and-burn farming is that.A) it does no harm to the topsoil of the rainforestB) it destroys rainforest soilsC) it helps improve rainforest soilsD) it diminishes the organic matter in rainforest soils12. Most rainforest soils are thin and poor because.A)B) black carbon is washed away by heavy rainsC) organic matter is quickly lost due to heat and rainD) long-term farming has exhausted the ingredients essential to plant growth13. Glaser made his discovery by.A) studying patches of fertile soils in the central AmazonB) examining pottery left over by ancient civilizationsC) test-burning patches of trees in the central AmazonD) radiocarbon-dating ingredients contained in forest soils14. What does Glaser say about the regrowth of rainforests?A) They take centuries to regrow after being burnt.B)C) Their regrowth will be hampered by human habitation.D) They can recover easily after slash-and-burn farming.15. From the passage it can be inferred that .A) human activities will do grave damage to rainforestsB) Amazon rainforest soils used to be the richest in the worldC) farming is responsible for the destruction of the Amazon rainforestsD) there once existed an urban civilization in the Amazon rainforests Passage TwoQuestions 16 to 20 are based on the following passage.Europes new economic climate has largely fostered the trend toward independence. The current generation of home-aloners came of age during Europes shift from social democracy to the sharper, more individualistic climate of American style capitalism. Raised in an era of privatization and increased consumer choice, todays tech-savvy(精通技术的) workers have embraced a free market in love as well as economics. Modern Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so.Berliner with a deep tan, teaches grade school in the mornings.

Passage ThreeQuestions 21 to 25 are based on the following passage.Supporters of the biotech industry have accused an American scientist of misconduct after she testified to the New Zealand government that a genetically modified(GM) bacterium could cause serious damage if released.The New Zealand Life Sciences Network, an association of pro-GM scientists and organisations, says the view expressed by Elaine Ingham, a soil biologist at Oregon State University in Corvallis, was exaggerated and irresponsible. It has asked her university to discipline her.But last week the New Zealand Life Sciences Network accused Ingham of“presenting inaccurate,careless and exaggerated information and “generating speculative doomsday scenarios( 世界末日的局面) that are not scientifically supportable. They say that her study doesnt even show that the bacteria would survive in the wild, much less kill massive numbers of plants. Whats more, the network says that contrary to Inghams claims, the EPA was never asked to consider the organism for field trials.Ingham says EPA officials had told her that the organism was approved for field tests, but says she has few details. Its also not clear whether the organism, first engineered by a German institute for biotechnology, is still in use.Whether Ingham is right or wrong, her supporters say opponents are trying unfairly to silence her. “I think her concerns should be taken seriously. She shouldnt be harassed in this way,says21. The passage centers on the controversy.A) between American and New Zealand biologists over genetic modificationB) as to whether the study of genetic modification should be continuedC) over the possible adverse effect of a GM bacterium on plantsD) about whether Elaine Ingham should be fired by her university22. Ingham insists that her testimony is based on.A) evidence provided by the EPA of the United StatesB) the results of an experiment she conducted herselfC) evidence from her collaborative research with German biologistsD) the results of extensive field tests in Corvallis, Oregon23. According to Janet Anderson, the EPA.A) has cancelled its approval for field tests of the GM organismB) hasnt reviewed the findings of Inghams researchC) has approved field tests using the GM organismD) hasnt given permission to field test the GM organism24. According to Ann Clarke, the New Zealand Life Sciences Network.A) should gather evidence to discredit Inghams claimsB) should require that the research by their biologists be regulatedC) shouldnt demand that Ingham be disciplined for voicing her viewsD) shouldnt appease the opposition in such a quiet way25. Which of the following statements about Ingham is TRUE?A) Her testimony hasnt been supported by the EPA.B) Her credibility as a scientist hasnt been undermined.C) She is firmly supported by her university.D) She has made great contributions to the study of GM bacteria. Passage FourQuestions 26 to 30 are based on the following passage.Every fall, like clockwork, Linda Krentz of Beaverton, Oregon, felt her brain go on strike. “I just couldnt get going in the morning, she says. “Id get depressed and gain 10 pounds every winter and lose them again in the spring. Then she read about seasonal affective disorder, a form of depression that occurs in fall and winter, and she saw the light-literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking its still enjoying those long summer days. It seems to work.Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and 25 million more develop milder versions. But theres never been definitive proof that treatment with very bright lights makes a difference. After all, its hard to do a double-blind test when the subjects can see for themselves whether or not the light is on. Thats why nobody has ever separated the real effects of light therapy from placebo(抚慰剂) effects.Until now. In three separate studies published last month, researchers report not only that lightWhy does light therapy work? No one really knows. “Our research suggests it has something todo with shifting the bodys internal clock, says psychiatrist Dr. Lewey. The body is programmed to start the day with sunrise, he explains, and this gets later as the days get shorter. But why such subtle shifts make some people depressed and not others is a mystery.That hasnt stopped thousands of winter depressives from trying to heal themselves. Light boxes for that purpose are available without a doctors prescription. That bothers psychologist Michael Terman of Columbia University. He is worried that the boxes may be tried by patients who suffer from mental illness that cant be treated with light. Terman has developed a questionnaire to help determine whether expert care is needed.In any event, you should choose a reputable manufacturer. Whatever product you use should emit only visible light, because ultraviolet light damages the eyes. If you are photosensitive( 对 光敏感的), you may develop a rash. Otherwise, the main drawback is having to sit in front of the light for 30 to 60 minutes in the morning. Thats an inconvenience many winter depressives can live with.26. What is the probable cause of Krentzs problem?A) An unexpected gain in body weight.B) Unexplained impairment of her nervous system.C) Weakening of her eyesight with the setting in of winter.D) Poor adjustment of her body clock to seasonal changes.27. By saying that Linda Krentz “saw the light(Line 4, Para. 1), the author means that she “.A) learned how to lose weightB) realized what her problem wasC) came to see the importance of lightD) became light-hearted and cheerful28. What is the CURRENT view concerning the treatment of seasonal depression with bright lights?A) Its effect remains to be seen.B) It serves as a kind of placebo.C) It proves to be an effective therapy.D) It hardly produces any effects.29. What is psychologist Michael Termans major concern?A) Winter depressives will be addicted to using light boxes.B) No mental patients would bother to consult psychiatrists.C) Inferior light boxes will emit harmful ultraviolet lights.D) Light therapy could be misused by certain mental patients.30. Which of the following statements is TRUE?A) Winter depressives prefer light therapy in spite of its inconvenience.B) Light therapy increases the patients photosensitivity.C) Eye damage is a side effect of light therapy.D) Light boxes can be programmed to correspond to shifts in the b
