写作第一套

【Directions】

For this part, you are allowed 30 minutes to write an?essay on why students should be encouraged to develop the ability to meet challenges.?You should write at least 150?words but no more than 200?words.

【参考范文】

In an ever-changing world, people are bound to face various challenges. However, challenges mean not only difficulties, but also opportunities. From my perspective, considering that there are many possibilities in our future,?we should not be afraid of challenges and encourage students to develop the ability to meet challenges.

There are several factors accounting for my view. In the first place, challenges can cultivate our personality. It is inevitable that we will encounter difficulties and problems. At critical times, one’s positive attitude towards challenges plays a crucial role in turning hardship into good results. In addition, it is challenges that can inspire our potential. Whatever situation we are faced with, people who have the ability of dealing with difficulties?have a greater chance of success. Individuals may achieve temporary success by good luck, but only after we go through the adversity on our own can we have the solid foundation of success.?

From what I have discussed above, we may safely draw the conclusion that?challenges may?have positive effects on our life. The earlier?we are aware of the optimistic side that challenges provide, the more benefits we will get.

【参考译文】

在瞬息万变的世界里，人们一定会面临各种挑战。然而，挑战不仅意味着困难，而且意味着机遇。在我看来，鉴于我们的未来有很多的可能性,我们不应该害怕挑战并且鼓励学生发展应对挑战的能力。

?有一些因素来解释我的观点。首先，挑战可以磨炼我们的品性。我们不可避免的会遇到困难和问题。在关键时刻，一个人对挑战的积极态度对于把困难转化为好结果起着至关重要的作用。另外，挑战可以激发我们的潜能。无论我们面对什么样的情况，有能力处理困难的人成功的机会更大。个人可能凭运气获得暂时的成功，但是只有当我们自己经历逆境后，我们才能有成功的坚实基础。

?从上面的探讨中，我们可以得出结论挑战可能对我们的生活有积极的影响。我们越早意识到挑战带来的乐观的面，我们将得到更多的好处。

Why students should be encouraged to develop communication skills

【参考范文】

There are all kinds of students with different personalities in our diverse university. Despite this, it is beneficial for all of us to develop effective communication skills, and there are a few arguments that can justify my opinion.

In the first place, as students, we inevitably face different groups of people: our roommates, our classmates, our professors and many others. Therefore, it is necessary for us to speak properly and avoid offending or hurting others when faced with certain kinds of people, which is the number-one social etiquette. Besides, those who can communicate effectively are often confident, popular, and make more friends. As a result, they tend to gain more respect and support from others when they feel in distress. Last but not least, effective communication with different people can broaden our horizons and cultivate our empathy, both of which are of utmost importance to our future lives.

All in all, it is okay to be either shy or outgoing, but it is worth pondering before socializing with other people, especially people who hold a different personality. Only in this way can we truly integrate with our communities with a sense of belonging.

【参考译文】?

我们的大学十分多元，有各种各样性格各异的学生。尽管如此，提升自己的沟通技巧对我们每个人都有益。以下几点可以证明我的观点。

首先，作为学生，我们不可避免地会面对各种各样的人：我们的室友、同学、教授，还有许多其他人。因此，我们能在某类人面前说话得体、避免冒犯或伤害他人的品质十分重要，这是最首要的一点社交礼仪。除此之外，善于沟通的人通常很自信、受欢迎，并且能交到更多朋友，这使得他们更容易赢得尊重，在遇到困境时也可能得到更多帮助。最后但也最重要的是，与不同的人进行有效的沟通可以拓宽我们的事业，培养我们的同理心，这两点对我们将来的生活都至关重要。

总的来说，不管内向还是外向都没问题，但与他人社交时我们还是要再三推敲，尤其是在面对与自己性格不同的人时。只有这样，我们才能真正融入集体，并获得归属感。

【Directions】

For this part, you are allowed 30 minutes to write an essay on?why students should be encouraged to develop creativity.?You?should write at least 150 words but no more than?200?words.

【参考范文】

When it comes to the importance of?creativity, people often naturally come to a consensus. Ironically, an increasing number of people?tend to?ignore?this capability. From my point of view,?students should be encouraged to develop a creative mind, especially in the digital era we are living in.

Firstly, in a time of information explosion when young people are immersed in a sea of messages, what they lack is not the ability to receive data, but the ability to think creatively. Students should learn to sift and organize various kinds of information in a creative way, so that they won’t feel lost oftentimes. Secondly, students need to develop their creativity because it will make them better prepared for their future career. Those who can come up with innovative solutions to the tricky issues they meet will be highly competitive at the workplace.

In summary, the importance of encouraging students to develop their creativity could never be overstated. Their parents and teachers need to realize this and provide the students with more opportunities to cultivate their creativity.

?【参考译文】

谈到创造力的重要性，人们往往会自然而然地达成共识。讽刺的是，越来越多的人倾向于忽视这种能力。在我看来，应该鼓励学生培养创造性思维，特别是在我们处在的数字时代。

首先，在信息爆炸的时代，年轻人被浸泡在信息的海洋中，他们缺乏的不是接收数据的能力，而是创造性思考的能力。学生应该学会以创造性的方式筛选和组织各种信息，这样他们就不会经常感到迷茫。其次，学生需要培养他们的创造力，因为这能让他们更好地为未来的职业生涯做好准备。那些能为他们遇到的棘手问题想出创新性解决方案的人，将在工作场所具有很强的竞争力。

总之，鼓励学生发展创造力的重要性怎么强调都不为过。学生家长和老师们需要意识到这一点，并为学生提供更多的机会来培养他们的创造力。

三、2010年12月份英语六级试题及答案解析 谢谢

快速阅读答案：1-7ABDADBB
仔细阅读答案：52-61ADCAC DBDDB
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。

62 B set out set out plans表示制定计划

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

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

69 B 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 D 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 A 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 C While 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 D 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 A 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 D suffered 遭受，suffer a loss遭受损失，常见搭配。

81 C 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。

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。
