1、大学六级-1216 及答案解析(总分：633.00，做题时间：90 分钟)一、Part Writing(总题数：1，分数：106.00)1.大家希望构建一个和谐社会，但社会上存在一些与和谐社会不相符合的现象2分析造成这种现象的不良影响3从自身应如何做起（分数：106.00）_二、Part Reading Compr(总题数：2，分数：70.00)MadagascarThere are at least 8 million unique species of life on the planet, if net far more, and you could be forgiven for be

2、lieving that all of them can be found in Andasibe. Walking through this rain forest in Madagascar is like stepping into the library of life. Sunlight seeps through the silky fringes of the Ravenea louvelii, an endangered palm (棕榈树) found, like so much else on this African island, nowhere else.Madaga

3、scar which separated from India 80 million to 100 million years ago before eventually settling off the southeastern coast of Africa, is in many ways an Earth apart. All that time in geographic isolation made Madagascar a Darwinian playground, its animals and plants evolving into forms utterly origin

4、al. Some 90% of the islands plants and about 70% of its animals arc endemic, meaning that they arc found only in Madagascar. But what makes life on the island unique also makes it uniquely vuhnerable, which means if we lose these animals on Madagascar, theyre gone forever.That loss seems likelier th

5、an ever because the animals are under threat as never before. Once lushly forested, Madagascar has seen more than 80% of its original vegetation cut down or burned since humans arrived at least 1500 years ago, fragmenting habitats and leaving animals effectively homeless. Unchecked hunting wiped out

6、 a number of large species, and today mining, logging and energy exploration threaten those that remain. It has an area the size of New Jersey in Madagascar that is still under forest, and all this incredible diversity is crammed into it.Madagascar is a conservation hot spot a term for a region that

7、 is very biodiverse and particularly threatened-and while that makes the island special, it is hardly alone. Conservationists estimate that extinctions worldwide are occurring at a pace that is up to 1 000 times as great as historys background rate before human beings began scattering. Worse, that d

8、ie-off could be accelerating. Price of ExtinctionThere have been five extinction waves in the planets historyincluding the Permian (二叠纪的) extinction 250 million years ago, when an estimated 70% of all terrestrial animals and 96 % of all marine creatures vanished, and, most recently, the Cretaceous (

9、白垩纪的) event 65 million ),ears ago, which ended the reign of the dinosaurs. Though scientists have directly assessed the viability of fewer than 3% of the worlds described species, the sample polling of animal populations so far suggests that we may have entered what will be the planets sixth great e

10、xtinction wave. And this time the cause isnt an unsteady planet or volcanoes. Its us.Through our growing numbers, our thirst for natural resources and, most of all, climate change- which, by one reckoning, could help carry off 20% to 30% of all species before the end of the century- were shaping an

11、Earth that will be biologically exhausted. A 2008 assessment by the: International Union for Conservation of Nature found that nearly 1 in 4 mammals worldwide were at risk for extinction, including endangered species. Over fishing and acidification of the oceans are threatening marine species as div

12、erse as the corals.Scary for conservationists, yes. but the question arises: Why should it matter to the rest of us? After all, nearly all the species that were ever alive in the past are gone today. Evolution demands extinction. When were using the term extinction to talk about the fate of the US a

13、uto industry, does it really matter if we lose species like the Yangtze River dolphin and the golden toad, all of which have effectively disappeared in recent years? What docs the loss of a few species among millions matter?For one thing, were animals too, dependent on this planet like every other f

14、orm of life. The more species living in an ecosystem, the healthier and more productive it is, which matters for us-a recent study by the World Wildlife Fund (WWF) estimates the economic value of the Amazon rain forests ecosystem services to be up to $100 per hectare (about 2.5 acres). When we pollu

15、te and deforest and make a mess of the ecological web, were taking out mortgages on the Earth that we cant pay back-and those loans will come due. Then there are the undiscovered organisms and animals that could serve as the basis of needed medicines as the original ingredients of aspirin were deriv

16、ed from the herb meadowsweet unless we unwittingly destroy them first.Forests razed can grow back., polluted air and water can be cleaned, but extinction is forever. And were not talking about losing just a few species. In fact, conservationists quietly acknowledge that weve entered an age of triage

17、 (挑选), when we might have to decide which species can truly be saved. The worst-case plot of habitat loss and climate change and thats the pathway we seem to be on-show the planet losing hundreds of thousands to millions of species, many of which we havent even discovered yet. The result could be a

18、virtual extinction of much of the animal world and an irreversible poverty of our planet. Hmnans would survive, but we would have doomed ourselves to what naturalist E.O. Wilson calls the Eremozoic Era the Age of Loneliness.So if you care about tigers and rhinos, if you believe Earth is more than ju

19、st a home for 6.7 billion human beings and counting, then you should be scared. But fear shouldnt leave us paralyzed. Environmental groups worldwide are responding with new methods to new threats to wildlife. In hot spots like Madagascar and Brazil. conservationists are working with locals on the gr

20、ound, ensuring that the protection of endangered species is tied to the welfare of the people who live closest to them. A strategy known as avoided deforestation goes further, incentivizing environmental protection by putting a price on the carbon locked in rain forests and allowing countries to tra

21、de credits in an international market, provided that the carbon stays in the trees and is not cut or burned. And as global warming forces animals to migrate in order to escape changing climates, conservationists are looking to create protected corridors that would give the species room to roam. Its

22、uncertain that any of this will stop the sixth extinction wave, let alone preserve the biodiversity we still enjoy, but we have no, choice but to try. We have a window of opportunity, but its slamming shut. To Save the Species, Save the PeopleMadagascar, which is called the “hottest of the hot spots

23、“, is where all the new strategies can be road tested. In 2003, after decades when conservation was barely on the governments agenda, then-President Marc Ravalomanana announced that the government would triple Madagascars protected areas over the following five years. That decision helped under fund

24、ed parks like Andasibes, which protects some of the last untouched forest on the is land. “You cant save a species without saving the habitat where it lives,“ says WWFs Roberts.Do that right, and you can even turn a profit in the process. In Madagascar, half the revenues from national parks are mean

25、t to go leo the surrounding communities. The reserves in turn help sustain an industry for local guides. In a country as poor as Madagascar, where 61% of the people live on less than $1 a day, it makes sense to give locals an economic stake in preserving wildlife rather than destroying it.The corrid

26、ors created by CIs Andasibe tree-planting program show how a small tweak can reduce the species killing effects of climate change-but also how longer-term fixes are needed. Fragmented habitats are problematic because many endangered species wind up trapped in green oases surrounded by degraded land.

27、 As global warming changes the climate, species will try to migrate, often right into the path of development and extinction. What good is a nature reserve-fought for, paid for and protected-if global warming renders it unlivable? Climate change could undermine the conservation work of whole generat

28、ions. It turns out you cant save species without saving the sky.That will mean reducing carbon emissions as fast as possible. In the US, the CBD has made an art out of using the Endangered Species Act, which mandates that the government prevent the extinction of listed species, to force Washington t

29、o act on global warming. The CBDs Siegel led a successful campaign to get the Bush Administration to list the polar bear as threatened by climate change, and we expect more species to follow.（分数：49.00）(1).What can we find in Andasibe?（分数：7.00）A.At least 8 million unique species of life.B.More than 8
