Many power plants have been modernized to give off less pollution and also moved further away from people's homes so as to decrease the damage.

⑹ 2010.12 英语六级答案

2010年12月大学英语六级考试答案

快速阅读答案：
1-10ABDADBB take risks have families military service
Part Ⅱ
Reading Comprehension（Skimming and Scanning）
1．A not be sustained in the long term
解析：关键字1994对应第一段第三行，题干中unsustainable即选项A中sustained的反义表达方式。选择A。
2．B Intergenerational conflicts will intensify.
解析：从书名定位到原文第二段，heading for the rock, the cleaner, 都暗示了两代人之间的问题，最后的warfare则一目了然地指出了该矛盾。
3．D politicians are afraid of losing votes in the next election
解析：首先需要理解题目意图，即为何养老机制改革迟迟不能进行，然后定位到文章第四段，其实只要从段落中politician这一关键字就能选定D选项。
4．A allow people to work longer
解析：从题干中the most effective method找到第五段第三句原话，直接选择A选项。
5．D younger workers are readily available
解析：题目中employer为关键字，找到第六段，该段看似没有直接提到为什么雇主不愿意雇佣old workers，但从其不断分析新涌现出来的劳动力替代者，可以总结的出D选项，即年轻劳动力的供给已足以满足企业需求。
6．B large numbers of immigrants from overseas
解析：这道题间接考察了学生变换思维的能力，Japan在文中一时难以找到，但其所代表的发达国家群体developed countries却出现在了第七段，而该段恰恰揭示了发达国家靠移民劳动力寻求养老机制危机一时的缓解的举措。
7．B They find it hard to balance career and family.
解析：compromise关键字找到第九段，关键字出现的句子前一句就是B选项。
8．take risks
解析：题目中old societies关键字对应到倒数第六段第三行，题目中的less inclined正好与原文中的more strongly disinclined形成对照，所以答案只需摘录之后的原文即可，即take risks
9．have families
解析：题目中关键字intergenerational warfare对应到原文倒数第五段。第二句直接对第一句做出了解释，摘录即可。
10．military service
解析：要理解题目中less willing to 的含义，即不情愿，这样定位到倒数第三段第一句的reluctant， commit sth. to sth. ，空格内需要填写名词，参照原文，即military service.

Part Ⅲ
Listening Comprehension
Section A
11. What can we infer from the conversation?
【答案】D The man is the manager of the apartment building

12. What is the woman eager to know?

14. What do we learn about the man from the conversation?

文章解析：
本文是一篇地理科学类文章，有点难度，关键是对一些专有名词的把握。文章开始先指出全球变暖带来最主要的威胁是极地冰盖的融化，并给出了相应的事实和数据加以证明。接着更多例子表明南极洲的冰盖在过去的130万年间至少坍塌过一次。相关高等学府的学者和科学家也相继用实验证明南极洲西部曾是一片汪洋。最后引用Herman Engle heart的话，再次提醒我们，西南极洲大冰原很可能再次融化消失。
其实按常理来说，如果听力文章比较有难度的话，题目的难度相对应会降低。所以大家在遇到此类题型时不必惊慌。提取关键信息、边听边记笔记，运用好背景知识等就能把题目做出来。平时也要注意扩大阅读范围，增长见识。关于环境保护和全球变暖之类的文章屡见不鲜，要求考生在这方面要引起足够的重视。
【难点词汇】
West Antarctic ice sheet西南极洲大冰原 ice shelf 冰架 anchored 固定的
fossil 化石 microscopic marine plants 海洋微生物 geological 地质的
26. What is one of the most frightening threats of global warming according to the passage?
【解析】C) Many coastal cities will be covered with water.
细节题。本题不难，从听力开头即可听到 “raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded” 所以选C选项。
27. What do scientists disagree on?
【解析】B) How unstable the West Antarctic ice sheet is.
细节题。本题不难。注意关键句 “but Antarctic experts disagree strongly on just how unstable it is” 即可得出答案。
28. What is the latest information revealed about the West Antarctic ice sheet?
【解析】A）It collapsed at least once ring the past 1.3 million years.
细节题。注意提取关键信息 “new evidence reveals that all or most of the Antarctic ice sheet collapsed at least once ring the past 1.3 million years” 所以选A选项。
29. What the scientists’ latest findings suggest?
【解析】A) The West Antarctic region was once a open ocean.
细节题。听力最后的例子说明了这一点“which suggest that the region was once open ocean not solid ice”， 而其他选项都不是最新的发现。

Passage Two
30 B）Whether a deleted photo is immediately removed from the web.
【解析】听力一开始作者就建议我们尝试删除自己上传的照片“Take a photo and upload it to Facebook, then after a day or so, note what the URL link to the picture is and then delete it.”，由此可知应该选B。
31 B) The way they store data.
【解析】“Why do "deleted" photos stick around so long? The problem relates to the way data is stored on large websites”，从这句话可知图片之所以不能立即删除跟它们存储的方式有关。

32 C) When the URL is reused.
【解析】“In the case of Facebook, the company says data may hang around until the URL in question is reused”，从这句话可知只有URL被再次用到才会被删除。
Passage Three
33. A
解析：第一段原文可以找到对应句子，即some iced coffees contain as many calories as a hot dinner.
34. B
解析：第一段原文中有对应语句，即Better skip dinner or hit the gym afterwards.
35. C
解析：在此句中，“The WCRF has estimated that 19,000 cancers a year in Britain could be prevented…”，关键词prevented可以得知答案为C选项。
Section C
36. diverse
37. tragic
38. commit
39. outcome
40. scale
41. colleagues
42. accurate
43. averages
45. Students with high hope set themselves higher goals and know how to work to attain them,
46. went beyond the simple notion that hope is merely the sense that everything will turn out all right.
47. Having hope means believing you have both the will and the way to accomplish your goals, whatever they may be.

Part Ⅳ
Reading Comprehension（Reading in Depth）
Section A
47.
答案：feminine and weak
解析：文中提到…because they believe that such feelings are feminine and imply weakness. 要填在to be后面就应该转化成形容词形式。
48.
答案：lose composure
解析：文中提到may lead to a loss of composure。要用在主语后面就要把loss变成动词lose。
49.
答案：stress-related disorders
解析：文中提到can contribute to stress-related disorder。
50.
答案：their relationship with partners
解析：文中提到…report lower relationship satisfaction as do their female partners.故这里要重新组合转换表达形式。
51.
答案：aggressive
解析：文中提到…into physically aggression or violence，而此处在become后就要用aggression的形容词形式。

52) A solve virtually existing all problems
细节题。抓住时间点“In the early 2oth century” 我们从第一句 “offer solutions to almost every problem” 便可知道答案。选择A选项。

53) D They realized that science and technology alone were no guarantee for a better world.
推论题。 我们首先比较容易排除A和C项。B项具有迷惑性，关键是看“the stability of a society depended heavily on humanistic study”这个选项仔细看就会发现说得太绝对了，社会的问题主要是靠人文主义的研究？显然不是很恰当。我们从下面那句也可以推断出选D比较恰当。 “Two world wars and a Great Depression rocked the confidence of many people that scientific expertise alone could create a prosperous and ordered world.”

54) C America is lagging behind in the STEMS disciplines.
细节题。主要在第二段里找答案。从段落后两句“There is considerable and justified concern that the United States is falling behind much of the rest of the developed world in these essential disciplines.” 我们可以推断出是选C选项。 A和D选项比较容易排除。不选B选项，因为文章中 “India, China, Japan, and other regions seem to be seizing technological leadership.” seem to 表明这几个国家只是有种趋势，但还没有have overtaken。

55) A Insufficient funding.
细节题。我们在第三段里可以找到答案。 从“…are seriously underfunded…” “Humanists are usually among the lowest-paid faculty members…” 这些信息中，可以很快知道是A选项。

56) C Humanistic thinking helps cultivate and define our culture and values.
细节题。本题不难。作者为什么如此着重人文主义的研究，其他三项都是非常具体的，且都不是重点。只有C选项符合。且我们从最后这一句 “But try to imagine our world as well without the remarkable works that have defined our culture and values.” 及作者的语气可以更加确定是C选项。

第二篇：
57. D. It will be some time before a new Einstein emerges.
解 析：这道题针对开头两节。A和C答案比较容易排除，A说爱因斯坦把数学推到了一个极限，C说在将来的两百年都不会有物理学家超过爱因斯坦，这两个都明显不 合文章大意。B答案说需要一个爱因斯坦才能建立一种大一统理论，属于过度推理，并且细节性太强了。D答案是正确答案，很多同学不敢选D的原因是，因为有些 科学家们认为爱因斯坦或许还没有诞生或许还是个小婴儿，他们认为这样一来就有可能爱因斯坦已经存在了。但是这句话里面的爱因斯坦是代表伟大的科学家的意 思，那么这个题目选择D就是正确的，大家都同意的是像爱因斯坦那样伟大的科学家还需要一定的时间才会出现。

58. B. His independent and abstract thinking
解析：B他独立与抽象思维能力。这一段是文章中间部分的内容概括。根据上下文意思推断，爱因斯坦成功的原因，不能说是他在音乐方面的天分，也不能说他的努力或者他在数学方面的深厚基础，因此答案选择B。

59. D. They often go into fields yielding greater financial benefits.
解析：正确答案选择D。这段文章是在问今天的物理学家们的情况， A说他们缺乏分析能力，B说他们擅长处理实际问题，C说他们重视发表文章，都是从根据文章细节中捏造出来的错误选项。D是对于文章内容的一个总结概括，数量众多的物理学家进入了更有经济利益的领域。

60. D. Nobody will read papers on apparently ridiculous theories.
解析：正确答案选择D。结合Greene讲的话，他说What an idea!还说是需要把头往墙上撞的人才会相信能找到个解决方案呢！说明内容实在是比较荒诞。

61. B. was little known in academic circles
解 析：正确答案选择B，说的是爱因斯坦在学术圈里面默默无闻，跟原文里面的“by a virtual unknown”相对应。有迷惑性的选择项是D,因为文中提到了爱因斯坦的文章没有配上脚注和注释footnote and citations.但是D选择项是说，爱因斯坦不懂得论文的格式，这个属于过度推理了。

Part Ⅴ
Cloze
62 B set out set out plans表示制定计划

63 D abandoning abandon 放弃，once unshakeable orthodoxy表示曾经不可动摇的做法，也就是现在要放弃了。

64 A with struggle with表示同…斗争，介词搭配，这里表示设法应对广告收入和报纸销售量下降的局面。

65 B intends intend to表示打算…,从后面的at the beginning of 2011，可知还没有这么做，只是计划或者打算这么做。

66 A exceeded 超过，是说当用户每月阅读文章超过一定量时就要收费。

67 A on 和side搭配，on the side of …表示拥护…；站在…一边。

68 D charge 本词在文章中多次出现，charge sb表示向某人收费。

69 C such as 表示举例，从后面举London's Evening Standard作为例子，可知应该选such as.

70 B free 前面提到abandon readership revenue，即放弃读者收益，由此可知应该是make print editions free.

71 C acknowledged 表示承认，这里表示Arthur Sulzberger承认这么做是一种赌博。

72 C bet 打赌，赌注，从前面的gamble可知应该选bet。

73 C circulation 发行量，从后面的数量可知应该选circulation。

74 A behind NYT排名第三，即排在the Wall Street Journal and USA Today后面。

75 B While在这里表示对比，从上下文可知NYT与美国其他报纸不同。

76 D claim 声称，宣称，这里是说NYT声称自己是全国范围的报纸。

77 C maintains 维持，运营，即NYT还在世界其他地方运营着26个办公室。

78 A like 从下文可知NYT和印刷行业的其他公司一样，也受到金融危机的影响，所以选like，表示同…一样。

79 D serious 严重的，考察形容词与名词的搭配，从下文的数据可知遭受严重经济损失。

80 C suffered 遭受，suffer a loss遭受损失，常见搭配。

81 D loan 贷款，前文提到公司损失了很多钱，所以需要从别处借钱来补充资金。

翻译答案：

82. There is no denying that you ___________(越仔细越好) in dealing with this matter.
解析：can never be too careful / can not be too careful
【考点解释】本题考查“越仔细越好”“再…也不为过”的固定搭配，即can never be too/can not be too + adj.
【原句精释】无可否认，处理这件事，越仔细越好。

83. Only when I reached my thirties __________________________ (我才意识到读书是不能被忽视的)
解析：did I realize that reading cannot be neglected
did I realize that reading is unignorable
【考点解释】本题考查由only when 引起的局部倒装。当only when置于句首，主句用局部倒装，即将助动词置于主语前面。only when引导句子时态为过去时（reached），为保持时态一致，主句助动词用did；注意被动语态的使用，reading与neglect为被动关系。同时也可以使用be+adj的结构。
【原句精释】直到三十岁，我才意识不能忽视读书。

84. Much ___________________ (使研究人员感到惊讶)，the outcome of the experiment was far better than they had expected.
解析：to the researchers’ surprise
【考点解释】本题考查固定搭配 to one’s surprise 使…惊讶的是…
【原句精释】让研究人员大为惊讶的是，实验结果比他们的预计好得多。

85. Oh, my, I can’t find my key; __________________________（我一定是把它放在哪儿了）。
解析：I must have left / put it somewhere.
【考点解释】本题考查对过去事情的肯定的猜测，即must have+过去分词，leave与put都有放置的意思，但leave强调遗忘在…，较之put，leave更贴合题意。
【原句精释】天啊，我找不到钥匙。我一定是把它放在哪儿了。

86．I ________________________(宁愿加入你们去做义工)than go to the beach for a holiday.
解析：would rather join you as a volunteer
【考点解释】考查结构“宁愿…也不愿…”, 因题干中已存在“than go”的结构，只能使用 “would rather do rather than do”。加入… join sb
【原句精释】我宁愿加入你们去做义工，也不愿到海边去度假

⑺ 英语作文 中国大学与美国大学的不同之处

美国人认为大学本科教育是一个自由人最基本的教育，它帮助一个体成长为一个具有理性思辨能力和批判精神的健全人。
Americans believe that university ecation is the most basic ecation, a free man it helps a indivial grow into a rational thinking and critical spirit of healthy people.

而中国的大学教育，由于历史和经济发展水平等诸多原因，还被定位成培养某方面专业人才的专才教育。
While China's university ecation, e to many reasons such as history and economic developing level, also is positioned into the training of specialists in the field of some aspect of specialist ecation.

双方最大的区别在于，前者之目标是为了培养健全的个体，使其成为一个称职的文明社会公民；而后者之目标在于培养工具式的人才。由于两者在目标上存在着本质的区别，因此中美大学教育在其他诸多方面也存在着根本性的差别。他们又可以集中地体现在专业选择和课程设置上。
The goal of both the biggest difference is that the former is to cultivate a healthy indivial, make it become a qualified citizen civilized society; The goal of which is in the tool type training of talents. Because there is essential difference between both in the target, so the university ecation of China and the United States in many other areas there are fundamental differences. They can be clearly reflected on the professional choice and the curriculum.

中国的大学生在入学前，就已经确定了某一专业。并且，从进入大学的第一学期，就开始学习专业课程。并且，中国的大学课程中，专业课程(包括核心课程和相关课程)至少占到总课程数的60%以上。
China's college students in front of the entrance, has identified a professional. And, from entering the university of the first semester, began to learn professional courses. And China university courses, professional courses, including core courses and related courses) at least accounted for over 60% of the total number of courses.

美国的大学生在进入大学时并无专业之分，而是按照一定的要求学习一些公共科目。这些科目一般要涵盖一些几各大系：文学、艺术、历史、哲学、人文、社会、数学、科学等几大领域。学生在经过比较广泛的教育后，能够更加清楚地了解自己，了解社会以及了解各个学科的内涵。
College students in the United States no professional when entering the university, but studying some common subject according to certain requirements.
