乒乓球 乒乓球是一项强调耐力和反应能力(reflexes)的运动，尽管乒乓球本身比较小，运动强度不大。不论男女老少都可以同台公平竞争。由于是室内运动，所以可以常年举行比赛或进行练习。自从乒乓球运动诞生以来，它已经经历了巨大的演变。比赛规则经过多次的修改，并且随着技术的进步和打球方式的改变，运动器材也发生了变化。这些改良(refinement)只是证明了乒乓球运动已经发展为一项非常完美的运动，可以与我们所崇尚(with reverence)的任何一种经典运动相媲美。 Despite its small size and moderate intensity, ping-pong is a sport that emphasizes endurance and reflexes. People of all ages and genders can play it on an equal ground. The sport is played indoors, so year-round competition and practice are possible. Ping-pong has undergone enormous evolution since it came into being, with has experienced many revisions of rules and seen an improvement of equipment as technology and playing styles changed. Such refinement only serves as evidence that ping-pong is indeed a full-fledged sport, comparable to any of the other classics we behold with reverence. 清华大学 清华大学被视为中国最著名和选拔人才最严格的大学之一。清华大学的校园位于北京西北部的海淀区，这是专为大学指定的区域。它坐落在清代皇家花园的旧址上，保留了一些中式的园林风格以及一些传统的建筑，但它的许多建筑物都是西式风格的，反应了美国对它的影响。它拥有中国最美丽校园之一，拥有中国最好的工程和应用科学 (applied science)课程，吸引了全国最有才华的学生，其地位和美国伯克利大学 (Berkeley)、麻省理工学院以及斯坦福大学相当。 Tsinghua University is regarded as one of the most renowned and most selective universities in China. The campus of Tsinghua University is situated in northwest Beijing, in Haidian District which is designated for universities. It is located on the former site of Qing Dynasty royal gardens and retains some Chinese-style landscapes as well as some traditional buildings, but many of its buildings are Western-style reflecting the American influence on its history. With one of the most beautiful campuses and the best engineering and applied science programs in China, it attracts the most talented students of the nation and occupies a position similar to Berkeley, MIT, and Stanford University in the US. 儒家思想 儒家思想是中国传统文化的基石。它出现在大约2500年前的春秋时期(the Spring and Autumn Period)，是建立在夏、商、周朝的传统文化之上，并由孔子创立的完整观念体系(ideological system)。儒家思想博大精深，涵盖了人性、

A: Pizza Hut was started in 1958, by two brothers in Wichita, Kansas. Frank and Dan Carney had the idea to open a pizza parlor. They borrowed $600 from their mother, and opened the very first Pizza Hut. In 1959, the first franchise unit opened in Topeka, Kansas. Almost a decade later, Pizza Hut would be serving one million customers a week in their 310 locations. In 1970, Pizza Hut was put on the New York Stock Exchange under the ticker symbol PIZ. B: In 1986, Pizza Hut introduced delivery service, something no other restaurant was doing. By the 1990's Pizza Hut sales had reached $4 billion worldwide. In 1998, Pizza Hut celebrated their 40th anniversary, and launched their famous campaign "The Best Pizzas Under One Roof." In 1996, Pizza Hut sales in the United States were over $5 million. Out of all the existing pizza chains, Pizza Hut had the largest market share, 46.4%. However, Pizza Hut's market share has slowly eroded because of intense competition from their rivals Domino's, Little Caesar's and newcomer Papa John's. Home delivery was a driving force for success, especially for Pizza Hut and Domino's.

六级新题型段落翻译练习 1、中国是舞龙舞狮的起源地。自问世以来，舞龙、舞狮运动一直受到各个民族人民的喜爱，代代相传，长久不衰，并因此形成了灿烂的舞龙舞狮文化。长期以来，很多青年朋友都以为龙舞、狮舞就是春节、庙会、庆典时的喜庆表演，殊不知它历经了几千年的传承流变，积淀了深厚的历史文化，是祖先留给我们的极其宝贵的文化遗产。 China is the dragon dance lion dance originated.

For a long time, a lot of young friends all thought the dragon dance, lion dances of the festival is the Spring Festival, temple fair, festival show, but it went through thousands of years of inheritance rheological, accumulated a profound historical culture, is the ancestors left us precious cultural heritage. 2、旗袍，是中国女性的传统服装，源于中国满族女性的传统服装。因为满族人被称为“旗人”，所以满族人的长袍被称为“旗袍”。到了20世纪20年代，受西方服饰的影响，经过改进之后的旗袍逐渐在广大妇女中流行起来。在中国，很多女性都喜欢穿旗袍。结婚的时候，新娘不仅要订做一件中式旗袍作为结婚礼服，还要穿着漂亮的旗袍照一套婚纱照，作为永久的纪念。对于中国的女明星们而言，旗袍也成为她们参加各种重要活动的首选礼服。 Cheongsam is a traditional Chinese women's clothing, from China's manchu women's traditional costume. Because the manchus were known as the "eight banners", so the manchus robes are known as "cheongsam". In the 1920 s, influenced by western clothing, after improving the qipao became popular among the masses of women in gradually. In China, many women like to wear qipao.

Though Shanghai cannot rival Beijing in cultural heritage, its varied architectural styles and cosmopolitan feel give it a charm of its own. Today's Shanghai has become a world-famous international metropolis.

Section B Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Into the Unknown The world has never seen population ageing before. Can it cope? [A] Until the early 1990s nobody much thought about whole populations getting older. The UN had the foresight to convene a “world assembly on ageing” back in 1982, but that came and went. By 1994 the World Bank had noticed that something big was happening. In a report entitled “Averting the Old Age Crisis” , it argued that pension arrangements in most countries were unsustainable. [B] For the next ten years a succession of books, mainly by Americans, sounded the alarm. They had titles like Young Old, Gray Dawn and The Coming Generational Storm, and their message was blunt: health-care systems were heading for the rocks, pensioners were taking young people to the cleaners, and soon there would be intergenerational warfare. [C] Since then the debate has become less emotional, not least because a lot more is known about the subject. Books, conferences and research papers have multiplied. International organisations such as the OECD and the EU issue regular reports. Population ageing is on every agenda, from G8 economic conferences to NATO summits. The World Economic Forum plans to consider the future of pensions and health care at its prestigious Davos conference early next year. The media, including this newspaper, are giving the subject extensive coverage. [D ] Whether all that attention has translated into sufficient action is another question. Governments in rich countries now accept that their pension and health-care promises will soon become unaffordable, and many of them have embarked on reforms, but so far only timidly. That is not surprising: politicians with an eye on the next election will hardly rush to introduce unpopular measures that may not bear fruit for years, perhaps decades. [E ] The outline of the changes needed is clear. To avoid fisca(财政的）meltdown, public pensions and health-care provision will have to be reined back severely and taxes may have to go up. By far the most effective method to restrain pension spending is to give people the opportunity to work longer, because it increases tax revenues and reduces spending on pensions at the same time. It may even keep them alive longer. John Rother, the AARP’s head of policy and strategy, points to studies showing that other things being equal, people who remain at work have lower death rates than their retired peers. [F] Younger people today mostly accept that they will have to work for longer and that their pensions will be less generous. Employers still need to be persuaded that older workers are worth holding on to. That may be because they have had plenty of younger ones to choose from, partly thanks to the post-war baby-boom and partly because over the past few decades many more women have entered the labour force, increasing employers’ choice. But the reservoir of women able and willing to take up paid work is running low, and the baby-boomers are going grey. [G] In many countries immigrants have been filling such gaps in the labour force as have already emerged (and remember that the real shortage is still around ten years off). Immigration in the developed world is the highest it has ever been, and it is making a useful difference. In still-fertile America it currently accounts for about 40% of total population growth, and in fast-ageing western Europe for about 90%. [H] On the face of it, it seems the perfect solution. Many developing countries have lots of young people in need of jobs; many rich countries need helping hands that will boost tax revenues and keep up economic growth. But over the next few decades labour forces in rich countries are set to shrink so much that inflows of immigrants would have to increase enormously to compensate: to at least twice their current size in western Europe’s most youthful countries, and three times in the older ones. Japan would need a large multiple of the few immigrants it has at present. Public opinion polls show that people in most rich countries already think that immigration is too high. Further big increases would be politically unfeasible.

传统阅读题，在体裁上包含了常所用的各种文体，如记叙文、说明文、议论文、人物传记、新闻报道等。考题类型一般有细节题、主旨题、词义辨析题和推论题。而各类题目大都有自己的惯用句式。这些句式可以帮助考生了解考点是什么，要使用什么方法找到答案。所以，熟悉一些惯用句式对我们是非常有益的。现将惯用句式列举如下： 1)细节题。 Which of the following is NOT true according to the passage All the following statements are mentioned in the passage except that_____________ According to the passage，who(when，where，what，why，etc。)…….. 2)主旨题 The major point discussed in the passage is____________ The best title for this passage would be________________ The passage tells us___________ The author’s purpose in writing this passage is to_______ 3)词义推测题 The phrase“…………。”most probably means__________ The phrase“…………。.”in the context means___________ The word“……………”in Line X refers to_____________ Which of the following is closest in meaning to the sentence“…………” 4)推论题 It can be inferred／indicated from the passage that___________ It can be concluded from the passage that___________________ What is the author’s attitude towards the………。 The example of…………is given to illustrate that____________- 在了解完题型分类之后，我们就要弄清做题顺序。实际上，要做好传统阅读题，还是需要将查读、略读和细读结合在一起。具体答题步骤如下： a。仔细阅读文章第一段和最后一段。这两段通常会概括文章的主旨，也就是文后主旨题的答案。， b。回答主旨题。在看完两段话之后，可以先回答后面的主旨题。 c。查读文后细节题。根据文后题目，在文中找寻关键词。这些关键词有助于我们找到所需信息在文中的位置，完成细节题和词义推测题。 d. 略读文章。抓住文章里的标志性语言，段首句和段尾句(同“略读解题方法”)等，完成推论题。 2)简答题
新题型六级翻译练习(后附答案)
（1）原文：中国是世界上最大的发展中国家，人口约占世界总人口的22%。在过去相当长的时期里，由于诸多原因，贫困一直困扰着中国。20世纪80年代中期，中国农村绝大多数地区凭借自身的发展优势，经济得到快速增长，但少数地区由于经济、社会、历史、自然等方面的制约，发展相对滞后。中国政府在致力于经济和社会全面发展的进程中，在全国范围内实施了以解决贫困人口温饱问题为主要目标的有计划、有组织的大规模扶贫开发，极大地缓解了贫困现象。 （2）原文：北京有无数的胡同(hutong)。平民百姓在胡同里的生活给古都北京带来了无穷的魅力。北京的胡同不仅仅是平民百姓的生活环境，而且还是一门建筑艺术。通常，胡同内有一个大杂院，房间够4到10个家庭的差不多20 口人住。所以，胡同里的生活充满了友善和人情味。如今，随着社会和经济的飞速发展，很多胡同被新的高楼大厦所取代。但愿胡同可以保留下来。
（3）原文：要了解中国文化，就应该对中国的戏曲文化有所了解。中国地方戏种类很多，其中京剧是一个具有代表性的剧种。作为一个独立的剧种，京剧的诞生大约是在1840年至I860年。京剧是在吸收其他地方戏营养的基础上形成的。京剧有明确的角色分工;在念白上用北京方言;在音乐上以胡琴为主要伴奏乐器。由于京剧是在融合各种地方戏之精华的基础上形成的，所以它不仅为北京的观众所钟爱，也受到全国人民的喜爱。 （4）原文：中欧经济贸易合作取得了可喜的成果。欧盟巳经成为中国的重要经贸伙伴，是中国最大的技术供应方、第三大贸易伙伴和第五大实际投资方。2001年，中欧贸易达到766亿美元，比上一年增长11%，尤其是中国从欧盟的进口增长了 15.8%。我非常赞赏欧中贸协(Europe-China Business Association)与比中经贸理事会 (Belgium-Chinese Economic and Commercial Council)为发展中欧关系所做出的努力。中欧经济贸易合作具有广阔的前景。中欧经济具有很强的互补性，在贸易、投资、科技等领域具有很大的合作潜力。

大学英语六级各题型解析
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.”

Next，they imprinted a block of gold with a microscopic chessboard pattern of chemicals. Half the squares contained anchoring points for the protein. The other half were left untreated as controls.
