1、大学英语六级分类模拟题 435及答案解析(总分：703.50，做题时间：90 分钟)一、Part Reading Compr(总题数：0，分数：0.00)二、Section B(总题数：1，分数：71.00)Sea stars are wasting away in larger numbers on a wider scale in two oceansA. Sea stars off the nation“s eastern and western coasts are dying in large numbers and in the most undignified ways. The

2、ir colorful limbs are curling up at the tips. h-regular arms are detaching from dying bodies like tails from lizards and swaying until they also drop dead. Ulcers are opening holes in tissue, allowing internal organs to reveal. Marine scientists say the sea stars are under attack by an unknown wasti

3、ng disease that turns their bodies to goo, and the results are nasty and horrible. B. All along the Pacific coast, sea stars are experiencing their largest known die-oft, which is affecting more species of sea stars than any other attack in recent memory, biologists said. A smaller and isolated Atla

4、ntic outbreak, at points off Rhode Island and Maine, has also been noted. C. Formerly known as starfish-a term scientists rejected because they“re more like a sea urchin (海胆) than a fish-sea stars have been killed by disease several times over the past few decades. But each of those events affected

5、only a single species, senior marine scientists said, not up to seven, as the new plague has. Divers have previously reported mass sea star deaths in warmer waters south of Santa Barbara, Calif., but not in waters as cool as those of Washington“s Puget Sound. D. Scientists disagree on the potential

6、ecological impacts of the current die-off. Sea stars control mussel (蚌) populations by relentlessly eating them, in their absence, mussels may proliferate and ruin portions of undersea forests that hide small fish from predators and help protect coastal areas from sea surge and storm flooding. That

7、impact “is very unlikely,“said John Pearse, a professor of ecology and evolutionary biology at the University of California at Santa Cruz, who believes scientists will figure the problem out before it gets out of control. E. But a colleague who is closely studying the disease isn“t so sure. “We are

8、at the onset of the outbreak,“ said Pete Raimondi, chair of the Department of Ecology and Evolutionary Biology at Santa Cruz. More important, said Drew Harvell, a Cornell University professor of ecology and evolutionary biology who studies marine diseases, “these kinds of events are signals of chang

9、e. When you get an event like this, I think everybody will say it“s an extreme event and it“s pretty important to figure out what“s going on.“ F. Scientists do know that wasting is happening on both coasts, but they don“t conclude if the two die-offs are linked. They know that tens of thousands of s

10、unflower stars have perished in British Columbia alone since the summer, but they don“t know exactly how many or every place there“s a disease outbreak. They decline to blame climate change or acidic waters or other warming-related issue, saying that would be just speculation. G. Not knowing is scar

11、y, Harvell said. If a similar thing were happening to humans, the Centers for Disease Control and Prevention would commit an army of doctors and scientists to unraveling the mystery. “We have far less resources with ocean organisms to get to the million-dollar question: What is the causative agent?“

12、 Harvell said. Is it a bacterium, a virus, a parasite or some disease introduced by an invasive species that jumped out of a ship that had been in foreign waters? H. What scientists agree on is that they aren“t close to knowing what“s causing the outbreak, let alone stopping it. Having first detecte

13、d it this summer, they“ve identified the illness as a wasting disease because sea stars fall apart and waste away, but they really don“t know much else. “It came from out of nowhere,“ said Laura Rogers-Bennett, a senior environmental scientist for the California Fish and Wildlife Service who studies

14、 sea stars near San Francisco. I. Raimondi started a Web site to track locations where sea stars are turning up dead, inviting anyone who sees one anywhere on the West Coast to report it. “We can build an infection map,“ he said. “Here“s where it exists and where it doesn“t exist. You can look for i

15、nitiation points, causes; if they initiated in warm water, you might have a conclusive evidence.“ J. Sea stars have endured localized wasting events in warmer waters, such as in Southern California in 1983 and 1997. But such disease is extremely rare in colder waters, “and that“s the most serious co

16、ncern for researchers,“ Rogers-Bennett said. Harvell said an event stretching from Southern California to British Columbia with multiple species is virtually unheard of. Pisasters, shaped like stars on the American flag, and vibrant sunflower stars as big as a trash can“s lid, are among the many sea

17、 stars affected. “We collected three different species just from here,“ Harvell said, referring to the Atlantic coast, “and five or six species on the West Coast.“ K. Along with dolphins, whales and sharks, sea stars are, well, stars of the sea. People can wade into the water and pick one up or scub

18、a (水肺) to greater depths and touch them where they live on reefs. They are harvested-unfortunately, biologists say-to be dried and turned into household decorations. L. In British Columbia, Neil McDaniel, a marine naturalist who dives into deep waters to photograph sea stars, said he“s shocked at wh

19、at“s happening there. It started in August, when a recreational diver in Howe Sound noticed that sunflower stars-among the world“s biggest, quickest and prettiest-“were kind of dissolving,“ McDaniel said. An emergency call to the Vancouver Aquarium brought scientists to the site. What they observed

20、sounded so awful that McDaniel had to see it for himself. “My team and I were astonished to see the devastation going on,“ McDaniel said. Sunflower stars are usually bright orange and plump, McDaniel said in a telephone interview. But these “looked feeble. The body walls were rupturing, the internal

21、 organs were falling out through ulcerations. It looked like the walking wounded.“ M. Over the past several years, Howe Sound had become almost overpopulated with sunflower stars, about a dozen per square meter in some areas, McDaniel said. Half the sea stars they saw this summer appeared infected.

22、N. When McDaniel returned about a month later, “there was 99 percent fatality. Tens of thousands died in Howe Sound alone in the course of one month,“ he said. “These are marvelous animals and such iconic animals, and to see so many of them dying kind of takes your breath away.“ Raimondi has been se

23、nding dead sea stars to labs for special studies. The bodies might hopefully yield a convincing explanation: a communicable disease, a toxin or a parasite. Similar research is happening at the University of Rhode Island. O. “We don“t know much yet,“ said Marta Gomez-Chiarri, a URI professor and rese

24、archer. Although sea star wasting in the Atlantic showed up for a long time, this episode has been under observation for only two months. “We know it is infectious and that whatever is affecting East Coast species can be transmitted to the West,“ she said. “I“m hoping this is a kind of infrequent bu

25、t natural event, and the sunflower star population will recover,“ McDaniel said. “You feel quite helpless. It“s hard to say if things will ever be the same.“（分数：71.00）(1).Researchers are most concerned about the extension of wasting disease from warmer waters to colder waters.（分数：7.10）(2).The new pl

26、ague in the Atlantic has been under observation for a relatively short time.（分数：7.10）(3).According to Harvell, scientific resources for ocean organisms are not enough to solve the mystery of sea star die-off.（分数：7.10）(4).Scientists do not think that the death outbreak of sea stars could lead to the

27、ruins of undersea forests.（分数：7.10）(5).It is expected that dead sea stars sent for special researches could produce a persuasive conclusion.（分数：7.10）(6).It is an unfortunate thing that sea stars are processed and used for household ornaments.（分数：7.10）(7).Previous reports about sea star deaths in the

28、 past few decades have never involved more than one species.（分数：7.10）(8).Some people attempt to gain effective evidence about causes of sea star die-off outbreak by making an infection map on the Internet.（分数：7.10）(9).Scientists haven“t yet established any connection between the sea star deaths on b

29、oth coasts.（分数：7.10）(10).Sea stars in Atlantic coast suffer a smaller scale of die-off compared with those in the Pacific coast.（分数：7.10）三、Part Translation(总题数：10，分数：632.50)1.中国园林是经过三千多年演变而成的独具一格的园林景观(landscape)。它既包括为皇室成员享乐而建造的大型花园，也包括学者、商人和卸任的政府官员为摆脱嘈杂的外部世界而建造的私家花园。这些花园构成了一种意在表达人与自然之间应有的和谐关系的微缩景观。典
