    问答题
    Not so long ago, people talked about global warming in apocalyptic terms—imagining the Statue of Liberty up to its chin in water or an onslaught of tropical diseases in Oslo. Recently, however, advances in our understanding of climate have moved global warming from a subject for a summer disaster movie to a serious but manageable scientific and policy issue. The greenhouse effect is nothing new; it has been operating ever since the earth formed. Without it, the surface of the globe would be a frigid –20 ℃ (–4 °F), the oceans would have frozen, and no life would have developed.

    正确答案：
    不久以前,人们提及全球变暖往往被认为是危言耸听,要么说水面上升会淹及自由女神像的下巴,要么说寒冷的挪威首都奥斯陆会遭到热带疾病的袭击。近来,我们对于气候的了解更加深入,全球变暖不再是一场炎夏的灾难,而是一个严重却可以控制和解决的科学和政策问题。温室效应并不是新现象,地球形成后就在发生。没有温室效应,地球表面的温度会低至零下20摄氏度(零下4华氏度),海洋会结冰,没有生命会产生。

  • 第12题：

    问答题
    Scientists hope that a remote lake on a dormant Chilean volcano can provide clues to what life may have been like in a far more distant place—the planet Mars.A 10-member team placed special plates in the lake on Licancabur volcano, at an altitude of 20,000 feet，on Sunday to measure the effects of ultraviolet light on organisms living there.The scientists, mostly from the United States, think learning how Licancabur organisms protect themselves may help researchers understand how life survived on early Earth and perhaps on early Mars as well.The damaging effects of UV radiation intensify at altitude and the air is very thin. And the lake is covered with ice most of the year, as would have been bodies of water on Mars.“If there was life on Mars 3.5 billion years ago, it could have used defense mechanisms similar to those used by the organisms at Licancabur volcano to survive,” said team leader Nathalie Cabrol.

    正确答案：
    在智利火山的顶端,有一个静谧的湖泊。近来,科学家发现了它的新价值——也许,它能告诉人们在更遥远的火星,早期的生命是如何存在的。
    11月10日,一个由10名科学家组成的小组在海拔2万英尺的利坎卡武尔火山顶端湖泊中放入了特殊的测量仪板,来测试紫外线照射当地的有机生物所产生的效果。
    以美国科学家为主的许多科学家都认为,研究利坎卡武尔火山的有机生物如何自我保护能够启发人们认识在早期的地球,生物是如何生存下来的,甚至也可以由此类推到早期的火星生命形态上去。
    在利坎卡武尔火山顶,紫外线辐射相当密集,杀伤力很强。空气也因为海拔高而非常稀薄,湖面上常年结着厚厚的冰层,与火星上的水域环境非常相似。
    研究小组的负责人纳塔莉·卡布罗尔说:“如果5亿年前火星上有生物的话,情况应该与利坎卡武尔火山顶生物生存下来所运用的防御机制大致相同。”

  • 第18题：

    Little help seems to_____ the disaster-hit area since the explosion took place 3 hours ago.

    A.offer
    B.have been offered
    C.be offered
    D.have offered

    答案：B
    解析：
    本题考查动词时态和语态辨析。题目意为“自从3小时前发生爆炸以来，灾区似乎没有得到什么帮助。”题干中，since意为“自……以来”，引导时间状语从句时常与完成时态连用，因此排除A和C选项。另外，此处help与offer在逻辑上是被动关系，表示帮助被提供，因此用被动语态，B选项符合题意。
