3、-local news,指 的是被传统新闻报道方式所忽略的小型社区或居民居住区里发生的相关信息报道。在美 国由此而诞生了 hyper-local news website,专门对主流媒体所没有覆盖的地区所发生 的事件进行报道,其形式多以网民,即短文中所提及的 citizen journalists,上传所 在社区发生的事件报道、照片或视频为主。这是网络时代产生的又一新生事物。3. data 是复数形式,但常用做单数,所以这里的代词是 it。另参见 最后 一段“As we collect this data, .”。这里的 data 也用作单数。4. phenology:物候学或生物气候学,是气

8、ata on a variety of common plants from across theUnited States.D) To investigate how plants and animals will respond as the climate changes.答案与题解:1. C第一段和第二段的第一句告诉我们,要在世界范围内观察气候对大自然中生物生命周 期的影响,数量有限的科学家不可能足迹遍及天下,为此科学家求助于普通公民的参与 。 所以 C 是正确选择。2. B第二段第三句中 encourage ordinary people to observe的主语是 The cit
9、izen scientist movement,即公民参与科学观察的运动。所以 D 不是正确选择。A 和 C 不符 合文章的句意,因此也不是正确的选择。这个句子的大意是:这一运动鼓励普通公民根 据自己的兴趣爱好进行科学观察,并将观察结果送交数据库,让专门领域的科学家做进 一步的观察。B 正确表达了这个意思。3. B one 在 这 里 是 一 个 代 词 , 其 前 置 词 是 citizen scientists , 而 不 是 citizen journalists,这里的 one 指的是 one of citizen scientists。所以 A、C 和 D 都不是 正确选择。这个句子
10、的意思是,只要每天或每星期花上几分钟收集数据并发送出去,就 能成为一个公民科学家。4. A 文章最后一段说,这个计划向所有人开放(open to everyone),所以应选择 A。B,C,D 所述内容都在该段中提到。5. D C 表述的内容是 Project Budburst 所要做的工作,但其最终的目的不仅仅是收集数 据,而是研究气候变化对生物生命周期的影响。因此,D 才是正确答案。第6篇 Arctic MeltEarths North and South Poles are famous for being cold and icy. Last year, however, the am
11、ount of ice in the Arctic Ocean fell to a record low1.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks during the summer. But for many years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drop in end
12、-of-summer ice cover2. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness - becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. Thats 38 percent le

This continuing trend has scientists concerned.There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer at the University of Wa
14、shington3 in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water4.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sun
15、light to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5Celsius warmer than average and 1.5 warmer than the previous record high5.With both air and water getting warmer, the ice is melting from both above
16、and below. In some parts of the Beaufort Sea6, north of Alaska and western Canada, ice that measured 3.3m thick at the beginning of the summer measured just 50 centimeters by seasons end.The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cov

20、eate. D) Expand.2. What is the ice cover in the Arctic by the end of 2007 summer?A) 4.2 million square kilometers. B) 11.4 million square kilometers. C) 1.13 million square kilometers. D) 38 million square kilometers.3. What are the reasons for the ice melt according to the scientists?A) Strong wind
21、s and clear skies. B) Long summer and short winter.C) Open water and thin ice. D) Light clouds and light winds.4. Why is the ice melting from both above and below?A) Because extra heat warms the air.B) Because extra heat warms the water.C) Because the temperature above the water is higher. D) Both A
22、 and B.5. What can be a possible title for the passage?A) What are scientists looking for in the Arctic Ocean? B) What are scientists doing in the Arctic Ocean?C) Why are scientists worrying about the Arctic Ocean? D) Why are scientists interested in the Arctic Ocean?1D build 是个多义词,四个选项都是该词的潜在词义。但在第
23、二段的第一句中,build 与后半句中 shrink(become smaller)一词相对,意思是 become bigger 之义。Extend 是增 长的意思,不适合用在此处。2A 答案可在第四段的第二句中找到。该句的意思是:2007 年夏末,冰的覆盖面积已经 缩小至 420 万平方公里。3A 短文的第五和第六段回答了这个问题。第五段告诉我们,由于强风的原因,大面积海 面仅有薄冰覆盖或没有冰层覆盖。第六段告诉我们,晴朗的天空使太阳直接照射海面,导致 高温。所以 A 是正确选择。B 的内容没有在文中提到。C 的表述内容是间接原因,是刮强风 的结果。D 选项中,light clouds 的确
24、是 ice melt 的原因,但 fight winds 是错误的理解。4D 答案可在倒数第三段第一句话中找到。from both above and below 的意思是:无论 从海水上面还是底下,也就是说,无论是海水还是海面上的空气。所以 A 和 B 都回答了问题 : 高温不但可能使水温增高,也使气温增高。5C 本文描述了科学家对北冰洋冰覆盖量的研究,研究结果是 Arctic is stuck in a warming trend from which it may never recover(北冰洋变暖的趋势可能不会逆转)。第四段最后一句说:This continuing trend h
25、as scientists concerned,短文最后一句也 告诉我们,科学家对这种趋势十分忧虑(fear)。所以,C 是本题的答案。第33篇 Experts Call for Local and Regional Control of Sites for Radioactive WasteThe withdrawal of Nevadas Yucca Mountain as a potential nuclear waste repository1 has reopened the debate over how and where to dispose of spent nuclear
26、fuel and high-level nuclear waste. In an article in the July 10 issue of Science, University of Michigan2 geologist Rodney Ewing and Princeton University3 nuclear physicist Frank von Hippel argue that, although federal agencies should set standards and issue licenses for the approval of nuclear facilities, local communities and states should have the final approval on the siting of these facilities. The authors propose the development of multiple sites that would
