一、阅读理解（本大题共4小题，共8.0分）
A
? ? After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves. ????Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced?by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around. ????The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources(来源) for the wolf-grew rapidly. These animals consumed large amounts of vegetation(植被)，which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park's red foxes, and completely drove away the park's beavers. ????As early as 1966，biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets. ????The government spent nearly 30 years coming up with a plan to reintroduce the wolves. The U. S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

答案和解析
1.【答案】
【小题1】D
【小题2】C
【小题3】A
【小题4】B
【解析】【文章大意】本文介绍了将灰狼重新引入黄石国家公园的起因结果等。政府花了近30年时间想出了重新引进狼群的方法，如今虽然对于狼群的适应性仍有争议，但黄石公园的生态系统确实有所恢复，这也为生物学家以后在其他地方重新引进狼群提供了借鉴。 1.主旨大意题。A项，"美国的野生动物研究"。B项，"黄石地区的植物多样性"。C项，"农民与苍狼之间的冲突"。D项，"黄石公园重新引入苍狼"。根据文章首句 After years of heated debate, gray wolves were reintroduced to Yellowstone National Park 以及全文大意可知，本篇文章都是围绕苍狼被重新引入*_**展开叙述的，D项符合题意。A、B、C项都是围绕着这个主题提及的某个方面，并没有大篇幅描写，故排除。故选D。 2.词义猜测题。根据文章第二段第一句 Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually?displaced?by human development.可知，在黄石地区本来苍狼随处可见，但是由于人类文明的发展它们逐渐被迫离开这个区域。displace 意为"取代，移走"，C项的 force out 意为"把…赶走，迫使离开"，与题意相符。test 意为"测试，测验"，track down 意为"追寻，查获"，均不符合题意。separate 意为"分开，分离"，但是这里强调的是"被迫离开"，不是"主动分离"，故排除。故选C。 3.推理判断题。根据第三段段意，可知苍狼的消失会使鹿群增加，它们破坏植被，从而减少植物多样性，破坏生态平衡。A项意为"破坏当地生态"，符合题意。B项文中未提及，排除。C项意为"保留植被"，与文意相反，排除。D项意为"动物多样性增多"，文中只是提到某些动物数量增加，并未提及种类增加，故排除。故选A。 4.推理判断题。根据最后一段段意及最后一句 The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.可知，苍狼的引进对黄石地区的生态平衡有很大帮助，而且这对于是否让其他地区也引进苍狼具有参考价值。所以作者对于引进苍狼的态度是积极的（positive），B项符合题意。doubtful 意为"怀疑的"，disapproving 意为"不满的，反对的"，uncaring 意为"冷漠的，不关心的"，均不符合文意。故选B。 5.【答案】
【小题1】B
【小题2】A
【小题3】D
【小题4】B
【小题5】D
【小题6】A
【小题7】D
【小题8】B

【解析】【文章大意】本文主要讲了作者的一个学生Freddy既有趣又有同情心。作者在他高中毕业前送给他一件衬衫，上面写着告诫他"动词"在人生中的重要性。而他在毕业后也保持着乐于助人的品质，但是不幸的是他在若干年后去世了，而那件衬衫也回到了作者的手中，作者以及他的学生都从他身上学到了一些宝贵的品质。 ?1.句意：每天，有27个孩子进入思维实验室。built建立；entered进入；decorated庆祝；ran运转。结合后文可知，这个思维实验室其实是一个普通的房间，这是同学们为它取的名字，可知使用动词表示“进入”这个思维实验室最合理。故选B。 2.句意：在认为104房间太呆板之后学生投票决定了这个名字。name名字；rule规则；brand品牌；plan计划。students voted for作定语从句，前面缺少一个名词。结合前文可知，这里应当是指“思维实验室”这个名字，思维实验室这个名字是学生投票决定的。故选A。 3.句意：在认为104房间太呆板之后学生投票决定了这个名字。small小的；dark黑暗的；strange陌生的；dull无趣的。学生们投票为这个房间取了名 内容过长，仅展示头部和尾部部分文字预览，全文请查看图片预览。 在分词作主语补足语，故填cheating。 36.【答案】Concerned
【解析】考查非谓语动词。be concerned about关心，担心。 concerned是-ed形式的形容词。句意：由于担心他生病的妻子，他在会后立即赶回家。根据句意和分析，此处是非谓语动词作状语。注意句首的单词首字母需大写。故填Concerned。 37.【答案】??Having thought
【解析】句意：考虑了一下情况，我决定向罗伊求助。考察非谓语动词，I与think是主动关系，用现在分词，think发生在decided之前，用现在分词的完成式。故填Having thought。 38.【答案】what
【解析】句意：读了她的自传，我沉浸在对Doris Lessing在文学上所取得的羡慕中。本句是一个宾语从句，从句缺少宾语，用what，故填what。 39.【答案】whose
【解析】句意：那是一台新机器，其零件小得看不见。本题考查定语从句，分析句子结构可知，先行词the?new?machine在从句中作定语，与parts是所属关系，故用关系词whose引导。根据分析，故填whose。
