2013年12月大学英语四六级改革新题型翻译专练（附答案）（强烈推荐） 翻译题 1. 澳门，南海之滨一颗闪耀的明珠，以她的风采、沧桑和辉煌，更以1999年12月20日这个不同寻常的日子，吸引着全世界的目光。自古以来，澳门就是中国的领土，中华儿女世世代代在这里繁衍生息。 早在80年代，世纪伟人邓小平就提出了"一国两制"的伟大构想。1997年7月1日，中华人民共和国恢复对香港行使主权。今年，澳门又将彻底结束外国管治，回到祖国怀抱，这是中华民族的又一件历史盛事，它标志着中国人民向着祖国统一的伟大目标又迈出了重大的步。澳门的明天一定会更好美好。 2．和平稳定是发展的前提和基础。上个世纪，人类经历了两次世界大战，生灵涂炭，经济社会发展遭受严重挫折。第二次世界大战结束以来，世界经济能够快速增长，主要得益于相对和平稳定的国际环境。 我们应该恪守联合国宪章宗旨和原则，充分发挥联合国及其安理会在维护和平、缔造和平、建设和平方面的核心作用。坚持通过对话和协商，以和平方式解决国际争端。 我们应该坚持国家不论大小、强弱、贫富都是国际社会平等一员，以民主、包容、合作、共赢的精神实现共同安全，做到一国内部的事情一国自主办、大家共同的事情大家商量办，坚定不移奉行多边主义和国际合作，推进国际关系民主化。 3.如果说我确实有所成就的话，那也只是因为我坚信不断尝试就会成功。遇到挫折时，你可以暂时把问题放一放，一味纠结不仅无济于事，有时反倒使情况更糟。先去读一本好书、见见久未谋面的好友或去户外骑游一番；再回头看待问题，你或许会感到柳暗花明。这样做后，别忘了多加反省：“为什么这个方法会奏效？下次能不能做得更好呢？”看你定的是什么目标，这种方法可以被反复有效应用。如果你坚定不移地持续提升自己，最后成功肯定非你莫属。孜孜不倦向来无敌。 4.关于吃月饼这个传统的来历有两个传说。一个是唐朝的神话故事，说的是当时地球被10个太阳包围着。有一天10个太阳同时出现在天空中，巨大的热量几乎把地球烤焦了。多亏一位名叫后羿的神箭手射下了9个太阳，地球才被保住。为了奖励后羿，王母娘娘赐给后羿一种长生不老药，但是王母警告他必须正当使用。然而后羿没有理会王母娘娘的警告，他被名利冲昏了头脑，变成了一个暴君。后羿美丽的妻子嫦娥对他的暴行再也不能袖手旁观，于是她偷走了后羿的长生不老药，飞到月亮上逃避后羿的狂怒。从此就有了关于月宫仙子嫦娥，这个月亮上的美丽女人的传说 5.在我的生活里，我也尝试过很多次试着放手。虽然，学会放手不会减轻生活里的伤痛或是改变什么，也不会让你的情绪得以发泄，也许你仍然会被生活所困。然而，富有同情心是一种释放。会让你和感受到你同情心的人得到精神上的洗礼。当你对一切都富有同情心时，你会发挥自己最大潜力。你也会在生活中觉得自己有无限的正能量 参考答案与解析 1.参考翻译及详解 澳门，南海之滨一颗闪耀的明珠，以她的风采、沧桑和辉煌，更以1999年12月20日这个

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Questions 21 to 25 are based on the following passage. In 1985 when a Japan Air Lines (JAL) jet crashed, its president, Yasumoto Takagi, called each victim’s family to apologize, and then promptly resigned. And in 1987, when a subsidiary of Toshiba sole sensitive military technology to the former Soviet Union, the chairman of Toshiba gave up his post. These executive actions, which Toshiba calls “the highest form of apology,”may seem bizarre to US managers. No one at Boeing resigned after the JAL crash, which may have been caused by a faulty Boeing repair. The difference between the two business cultures centers around different definitions of delegation. While US executives give both responsibility and authority to their employees, Japanese executives delegate only authority—the responsibility is still theirs. Although the subsidiary that sold the sensitive technology to the Soviets had its own management, the Toshiba top executives said they “must take personal responsibility for not creating an atmosphere throughout the Toshiba group that would make such activity unthinkable, even in an independently run subsidiary.” Such acceptance of community responsibility is not unique to businesses in Japan. School principals in Japan have resigned when their students committed major crimes after school hours. Even if they do not quit, Japanese executives will often accept primary responsibility in other ways, such as taking the first pay cut when a company gets into financial trouble. Such personal sacrifices, even if they are largely symbolic, help to create the sense of community and employee loyalty that is crucial to the Japanese way of doing business. Harvard Business School professor George Lodge calls the ritual acceptance of blame “almost a feudal (封建的) way of purging (清除) the community of dishonor,”and to some in the United States, such resignations look cowardly. However, in an era in which both business and governmental leaders seem particularly good at evading responsibility, many US managers would probably welcome an infusion (灌输) of the Japanese sense of responsibility, If, for instance,
2018年英语六级考试试题及答案 PartⅠWriting 1.【题干】For this part, you are allowed 30 minutes to write an essay on the importance of building trust between business and consumers. You can cite examples to illustrate your views. 150-200 words. 【答案】Without a doubt, a mutually-trusted relation between businesses and consumers is important for the two parties. First of all, though business is objective, cooperation is relatively subjective. Only when a consumer believe in what a businessman is selling, he or she could decide to buy something from the man. In reality, I have seen too many consumers purchase or refuse one commodity only because they like or dislike the salesman who they meet, especially when they are in a bad mood. Secondly, when one businessman consider that a customer trusts him, he would feel honored and satisfied thereby giving more preference to the customer. Naturally, when one businessman offers the best quality goods and the best prices to a customer, the customer has no excuse to refuse the businessman. Once such relation informed, both the two parties gain profit from it Hence, both businesses and consumers should work together to form a reciprocal relation. PartⅢReading Section A
2017年6月大学英语六级考试真题及答案解析（第三套完整版） Part I Writing (30 minutes) Directions: Suppose you are asked to give advice on whether to attend college at home or abroad, write an essay to state your opinion. You are required to write at least 150 words but no more than 200 words. 【参考范文】 Whether to Attend College at Home or Abroad? Currently, with studying abroad gains mounting popularity among people, there is a heated debate about whether to attend college at home or abroad. Opinions on this topic vary from person to person. Some see more benefits in studying at home while others claim that studying abroad is a more ideal choice as it?s more challenging. Personally, I am a strong favorer of the latter view. Listed below are the reasons for my advice. First of all, attending college abroad provides an opportunity to broaden one?s experience and mind. You can acquire cross-cultural experiences and gain new perspectives on your chosen field of study. In addition, studying abroad helps you to polish your social skills; you can make friends with different people with different background. Thirdly, overseas studying is conducive to the formation of an independent, autonomous and tenacious personality, which will ultimately benefit the achievement of our life goals. Just as an old saying goes: “It is better to travel thousand miles than to read ten thousand books.” Then studying abroad can not only enable us to reap in our books, but also in our trips. And this is why attending college abroad is a preferable selection for me. Part II Listening Comprehension (30 minutes) 说明：2017年6月大学英语六级真题全国共考了两套听力。本套（即第三套）的听力材料与第一套完全一样，只是选项的顺序不同而已，故本套不再重复给出。 Part III Reading Comprehension (40 minutes) Section A Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

大学英语四级阅读：选词填空技巧汇总 选词填空的考察形式 一篇280词左右的文章，文章中挖出10个空，并统一给出A-O 15个备选答案。选词填空区别于完形填空，有更大的解题难度，原因在于： 1. 完形填空每题都是四选一，选词填空第一题要十五选一，就算用到排除法，最后一题也要六选一，而且在十五个选项中还有五个根本不会用到，难度加大； 2. 完形填空每题的四个选项都是统一的词性，只需要辨析词义、搭配就基本可以作答，而选词填空的十五个选项有多个词性，解题时需要同时判断词性和词义，难度加大； 3. 完形填空每题的四个选项往往都是统一时态，统一形式，而在选词填空中会涉及选项的动词时态、第三人称单数形式、被动主动语态，名词的单复数等的辨析，难度加大。 针对选词填空的解题方法分为三步 1. 预览选项，了解词义并把选项分为四大类词性：名词n，动词v，形容词a，副词ad，在每个选项后作词性的简要标记； 2. 精读全文开头，把握文章主题，并以三个空或一个段落为一个单位，利用前后文判 断每空的词性； 3. 把对应词性的选项逐一带回原文，含义通顺，时态、主谓搭配一致的为正确选项。 四级考试的常用后缀在判断选项词性时可以有一定帮助作用。在根据前后文判断每空的词性时，一些经常考察的形式如下： 名词：通常来说，冠词(如a，an，the)、形容词、介词后面搭配名词，即"a/an/the/adj./prep. + n。"， 举例说明：Education soon became a _____. 冠词a后面加可数名词的单数形式，正确答案是nightmare，这句话的意思是"教育很快成了一种噩梦。" As the trade winds lessen in _____, the ocean temperatures rise causing the Peru current flowing in from the east to warm up by as much as 5 degrees. (06-6) 介词in后面加名词，正确答案是strength，这句话的意思是"当信风强度减弱的时候，海洋温度上升，导致从东部流入的秘鲁洋流上升了5摄氏度之多。"较难的一个例子：Husbands and children now do some of these jobs, a ____ that has changed the target market for many products. (06-12) 这里可以用两种判断方法来判断横线处所填词的词性。第一种方法，用句子结构来判断，前面一句话，husbands and children now do some of these jobs，这是一个完整的句子，主语husbands and children，谓语动词do，宾语some of these jobs；后面的that 引导的是一个同位语从句，它所修饰的中心词就是a后面需要填的词，而定语从句的中心词是名词，所以横线处应填一个名词。第二种方法，根据刚才所说的"a + 名词"的语法规则来判断，横线处应该填一个名词，而且是一个可数名词的单数形式。正确答案是situation。这句话的意思是"丈夫和孩子现在也做一些这样的工作了，这种情况就改变了许多产品的目标市场。" 动词：动词的考点很多，我们来看其中三种： 1. 主语后缺谓语动词。举例说明：He ____ from his teachers, came home in tears and thought about dropping out. 在这句话里，主语是he，本来后面应该有一个动词作谓语，但是这里没有动词，而是在横线后面出现了一个介词短语from his teachers，这样这句话就缺少谓语动词，所以横线上应该填一个动词。正确答案是hid，这句话的意思是"他不愿见老师，

六级阅读各题型有的放矢-简答及选词填空 在新六级的考试大纲中明确写出简答题和选词填空是或考题型，即每次考试考哪一道题都是不确定的，但是从改革之后的几次考察情况来看，大家或者也能感觉到哪一道题会重要些，从2006年12月开始实行新的题型，六次考试全都都考了简答题。但我们还是对两种题型做同样的分析。 简答题 考试大纲中，关于简答题的介绍如下： 简答题的篇幅长度约为400－450词，篇章后面有若干个问题，要求考生根据对文章的理解简洁地（少于10个词）回答问题或完成句子。 通常来说，简答题在一篇文章之后有五道题，这五题中问答和完成句子的数量是不确定的，有时多问题，有时多完成句子。那经过对历年真题的分析，我们发现此题的话题与传统阅读部分是非常相似的，基本上在交通、大众传媒、文化、网络这几个话题上，相对来说比传统阅读还要少一些。文章的难度相对较低，尤其是长难句的数量也有所减少。 此题难度较低，原因在于绝大多数题目都是细节题的考法，而此处不需要对原文信息进行同义替换，可直接抄写原文信息，故此题只需要进行定位即可。考生朋友把握三条原则，此题可解。 1）答案与问法一致原则。 做此题时，首先看题干，划关键词，同时还要对问法做出标记，根据问法的不同，考生的回答也应该有所不同，如2009年6月20日真题的第47，48两道题： 2）照抄原文原则 定位后，可以通过对比原文与题干，找出丢失信息，直接从原文中抄写即可，尽量不要对原文信息做改写，或调整，必要的时候也只是同一个单词的词性的变化。请看下面例题： 48. By promoting “body activism,” University of Texas psychologists aim to prevent ________. 利用划线的两处名词，可以在原文中找到如下的句子：What is surprising is the method psychologists at the University of Texas have come up with to keep girls from developing eating disorders. Their main weapon against super skinny (role) models: a brand of civil disobedience dubbed “body activism.”
做题技巧：做完快速阅读离听力开始还有五分钟，在这五分钟内老师会把你的答题卡1收上去，然后我们要做的就是浏览听力的所有选项。这段时间是充分发挥你记忆力的时候，记住的选项越多越好。加了长对话和考试和复合式听写之后听力时间变长了，很容易让人觉得疲惫，所以做听力的时候一定要保持最佳状态。 v一．卷子发下来后快速的浏览一遍，包括题干和答案。这样会大大提高你对听力的理解---知道它是讲什么内容，大概是怎么回事。 大学英语六级听力技巧 v二．没听懂的题目，就放弃它，千万不要在听下道题的时候还在想上道题。这样会引起头脑的混乱。 大学英语六级听力技巧 v三．相信第一感觉，听力部分不是非常确凿的感觉的话不要改动开始的答案。人的脑袋有时候会混淆的。因此很多情况下不是你选错了，而是改错了。因此轻易别选，但是选了之后轻易别改。 大学英语六级听力技巧 v四．复合式听写的句子部分是得分大户，也是丢分大户，一定注意听懂再写，以句子为单位而不是以单词为单位去写。写出主要意思即可。不会写的单词要用同义词来替换。 大学英语六级考试七大听力技巧与题型分析 v(一)提炼选项中的重要信息 v考生务必先看选项。当录音人开始宣读Directions 时，考生应充分利用这段时间速读选项，预测考点，从而做到心中有数。通过先看选项，可以明确题目多方面的信息： v1)题目涉及到的人物、地点、场合等，在非主题题型中，可能暴露该题的主题。考生可以通过对全部选项的速读建立起一个大概的场景，比如:图书馆、医院病房等，从而联想起与该环境有关的词汇，迅速进入状态; 大学英语六级考试七大听力技巧与题型分析 v(一)提炼选项中的重要信息 v提醒考生务必先看选项。当录音人开始宣读Directions 时，考生应充分利用这段时间速读选项，预测考点，从而做到心中有数。通过先看选项，可以明确题目多方面的信息： 大学英语六级考试七大听力技巧与题型分析 2)当四个选项是同类短语时，考点就在这一细节。这时，考生应充分集中精力，听懂时间、数字等与选项对应的细节考点; 大学英语六级考试七大听力技巧与题型分析 3)尽管四个选项中只有一个正确答案，其余的三个选项设置也并非和题目毫无关系。利用设定干扰选项所遵循的规律，我们可以大胆地进行猜想。这种猜测其实并不耽误时间，也不怎么消耗脑力，考生反而能够通过猜想事先得到一个对该题的印象。
