G The discussion on this subject has been heated, but what are scientists actually saying? At Readers Digest, we decided to find it out. 2. B Yes,
29、it has, and even warmer. Greenland was forested between 450,000 and 800,000 years ago, so temperatures were considerably warmer then. There have also been other times of relatively high temperatures.So why does the concern exist?Its all about the speed at which temperatures are changing. 3. E But in
30、 the 20th and 21st centuries, especially since 1976, temperatures have probably risen more quickly than during any century in the past 1,000 years. Warming may bring improved crop production and other benefits to northern countries such as Canada or Russia. However, many species may not adapt to the
31、se conditions, and the one that is able to may cause a problem. 4. F The West Nile virus, first seen in North America nine years ago, infected about 4,000 people in the US in 2006. The mountain pine beetle, which is active during warmer winters, has already destroyed about 13 million hectares of Can
32、adas forests, worth an estimated $6.4 billion.What is causing the warming?IPCC has concluded that human activity is very likely responsible, by increasing the concentrations of greenhouse gases and thus the greenhouse effect. 5.

33、r, still disagree.BHas the planet ever been this warm before?CHas human behavior made the planet warm?DTemperatures have been changing all the time.EIn the past, temperatures moved up or down gradually.FMosquitoes have been moving northwards to higher places.GThese questions have burst into newspape
34、rs, films and popular books.文章大意：本文是一篇议论文。主要内容是科学家关注引起气候变暖的真正原因，及对该问题的讨论。解析：1根据前文提出的两个问题可知，G选项中的these questions指代前文的两个问题；再根据下文可知，关于“气候变暖”的问题讨论一直很热烈，G选项中提到“气候变暖这些问题在报纸、电影和书籍中都提到过。”，由此可知，G选项能承接上下文。故选G。2根据下文的“Yes, it has, and even warmer”(是的，有，而且更暖和。)，可知此句是答语，由it has也可推知，问句的部分包含has助动词，B项符合这个要求，且语义(地球以前
35、有过这么温暖吗？)承接下文。故选B。3根据上下文可知，此处强调的是气候的变化，且E选项中的temperatures和上下文呼应，且语境承接上下文。故选E。4根据前文的“many species”(许多物种)可知，此处用“Mosquitoes”进行举例说明，因为一些物种无法适应这种环境，所以蚊子向北移到较高的地方。故F项承接上文，故选F。5根据上下文可知，政府间气候变化专门委员会得出结论，人类活动很可能是罪魁祸首，因为人类活动增加了温室气体的浓度，从而造成了温室效应。然而，一些科学家仍然不同意。他们认为人类的贡献微不足道。故A项承接上下文，且呼应本文主题。故选A。.语法填空(2020潍坊市6月模

In fact, another study found that from 1990 to 2010, more than 900 new glacier-fed lakes 8.were formed (

40、xpected it to even five or ten years ago.文章大意：本文是一篇说明文。由于气候变化，到2100年时，世界上将会有大约18 000处冰川消融。冰川消融会对人类生活造成什么样的影响？消融后的水都去了哪里？1考查冠词。形容词最高级前应使用定冠词the。the most comprehensive analysis表示“最全面的分析”。2考查非谓语动词。分析句子结构可知，空处为非谓语动词作伴随状语，warn与主语the International Centre for Integrated Mountain Development构成逻辑上的主谓关系，故用其现在
41、分词形式。3考查名词。该空前面有a bad修饰，应使用单数名词。4考查关系代词。空处引导非限制性定语从句，且在从句中作主语，从句修饰先行词South Asians，故用关系代词who。5考查副词。空处修饰动词melt，故用所给词的副词形式rapidly“快速地，迅速地”。6考查非谓语动词。分析句子结构可知，contain与the amount构成逻辑上的动宾关系，故用过去分词作定语。7考查代词。空处修饰后面的名词glaciers，故用形容词性物主代词its。8考查时态、语态和主谓一致。句子主语是more than 900 new glacier-fed lakes，与动词form构成动宾关系且表示复数；时间状语是from 1990 to 2010，应用一般过去时。故填were formed。9考查介词。此处表示科学家必须依靠人造卫星来计算它们的数量。rely on/upon“依靠，依赖”，为固定搭配。10考查比较级。根据空前的much和空后的than可知，空处应用所给词的比较级形式。
