第1题:Ten years ago, when environmental lawyer Kassie Siegel went in search of an animal to save the world, the polar bear wasn’t at all an obvious choice. Siegel andBrendanCummings of theCenter forBiologicalDiversity in Joshua Tree,Calif. , were looking for a species whose habitat was disappearing due to climate change, which could serve as a symbol of the dangers of global warming. Her first candidate met the scientific criteria—it lived in ice caves inAlaska’s GlacierBay, which were melting away—but unfortunately it was a spider. You can’t sell a lot of T shirts with pictures of an animal most people would happily step on. Next, Siegel turned to the Kittlitz’s murrelet, a smallArctic seabird whose nesting sites in glaciers were disappearing. In 2001, she petitioned theDepartment of the Interior to add it to theEndangered Species list, but Interior Secretary Gale Norton turned her down.Elkhorn and staghorn coral, which are threatened by rising water temperatures in theCaribbean, did make it onto the list, but as iconic species they fell short insofar as many people don’t realize they’re alive in the first place. The polar bear, by contrast, is vehemently alive and carries the undeniable charisma of a top predator.And its dependence on ice was intuitively obvious; it lives on it most of the year.But it took until 2004 for researchers to demonstrate that shrinking sea ice was a serious threat to the bears’ population. On FeB、16, 2005—the day the Kyoto Protocol to curb greenhouse-gas emissions took effect, without the participation of the United States—Siegel petitioned to list polar bears as endangere D、Three years later her efforts met with equivocal (不明确的) success, as Interior SecretaryDirk Kempthorne designated the bears as "threatened" (not endangered), a significant concession from an administration that has stood almost alone in the world in its reluctance to acknowledge the dangers of climate change. TheEndangered SpeciesActESA、, whose odd lists of snails and bladderworts sometimes seemed stuck in the age ofDarwin, had been thrust into the mainstream of 21st-century environmental politics.Break out the T shirts! It can be learned that the polar bear ______. A、was first considered by Siegel to be the iconic animal in 1998 B、was first proposed by Siegel to be the endangered species in 2004 C、was not qualified scientifically as the endangered species until 2005 D、was not officially under the government protection until 2008 |

第2题:Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent (61) must exist in the form of tiny particles or atoms and that these (62) be completely mixed together in the atmosphere. This threw a new light in (63) law of definite proportions. It was only necessary to suppose that the atoms (64) combine into small groups of uniform (65) and so form more complex substance; (66) the mystery of this law was (67) .Dalton suggested, for example, that carbon monoxide (68) formed by the one with one (69) of atoms of carbon and oxygen, (70) carbon dioxide results from a single (71) of carbon uniting with two atoms of oxygen.Assuming this to be true, (72) the definite proportions of Prout’s law (73) all chemical compounds the different constituents (74) enter in unvarying proportions would naturally (75) the relative weights of the many different kinds of atoms.
