2003年3月如果发生可怕的通货紧缩即价格的全面下降，则其原因与美国紧密相关，但欧洲和日本也难逃其咎。

美国具有投机性质的经济繁荣不可避免会崩溃，但是如果其他经济强国能够健康发展的话，美国经济的衰落本不会有这样巨大的破坏作用。

这些国家日益扩大的经济需求，本来可能有助于美国和巴西、南韩等所谓的新兴市场经济国家。

可问题是，这些国家的经济状况也远非理想。

如果世界上三大经济体同时遭受经济衰退，通货紧缩就可能出现。

价格之所以下降，是因为全球范围内，需求太小，供给太多—从钢材到鞋子，莫不如此。

日本的诸多问题广为人知，银行坏账肆虐。

但起码在美国，不太为人所知的是，欧洲的种种问题主要来源于德国。

如同日本是亚洲“病夫”一样，德国可谓欧洲“病夫”。

仅仅15年前，这些国家还跃跃欲试，准备领导世界经济，今天却已沦为巨大的拖累。

2003年9月二战开始以来，各大高校规模扩大，本科毕业生和博士毕业生人数激增。

这些，催生了一大批技术人员、助理人员、撰稿人、符号编制人员、调研人员和政策献言人。

现在他们在各类组织中，受雇于精明能干之士。

这些人，因为与符号和观念打交道，而被称之为知识分子。

他们已经完全像工程技术人员一样，职业化了。

但与工程技术人员不一样的是，这些职业知识分子无须从事繁重的日常例行工作—他们仅承担少量教学工作，同时享受政府及各类基金会科研拨款和津贴。

教授的课题预算是其在高校内赖以独立的首要经济基础。

课题预算使得研究生得以存在，并使得高校具有资金偿还能力，因为从每项课题预算中，高校都要抽取一定百分比的管理费。

不管是来自政府还是商界，课题经费的主要特征都是，它是以合约为基础的，不同课题立有不同合约。

因此，科研人员的独立性取决于他是否有能力获取一系列合约。

获取合约的能力是职业知识分子的一种真正才能。

2004年3月八年来，密歇根州州立大学的学生都是直接从联邦政府贷得学费的。

但去年春天，学校有关负责人取消了这一措施，转而与私营贷款业者和一家州立机构签订合约。

Dolphins, like whales, must surface to breathe air through a blowhole on top of their heads. Dolphins are social animals and love company. Many of them, in fact, even enj oy being around humans. It is not uncommon to hear of dolphins giving rides through the water to humans.In addition to being playful, dolphins are helpful to men. For example, as 400 B. C. the Greek poet Arion was saved from drowning by a dolphin. From then until now, dolphins have been helping swimmers who are in trouble. Swimmers, however, are not the only humans they help. In some parts of the world, they can be counted on to help men catch fish.Moreover, dolphins are very intelligent. A dolphin's brain resembles a human brain, but it is larger. Consequently, some people claim that dolphins are really smarter than men. Of course, there is no way of proving this point. Brain size is not an absolute measure of intelligence. Furthermore, measuring dolphins' intelligence in other ways is not possible since men cannot fully communicate with them. Apparently, however, dolphins communicate with each other. At any rate, they make whistling, clicking and buzzing sounds which seem to be at least a form of language. So far, however, men have not been able to figure out the communication code the dolphins use.每年春季，数以万计的中外客商云集申城，参加一年一度的华东出口品交易会。

翻译资格考试中级笔译经典译文2017年翻译资格考试中级笔译经典译文【第一题】I am very glad that all of you will soon go to the States to study and work with Americans. We need to eat no matter where. So, as the first lecture in the orientation program, I'd like to talk about what Americans do in a restaurant.In American restaurants, you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you get free refill.Soft drinks are sweet, carbonated drinks like Coke. Hard drinks are alcoholics, like whiskey. They are served either on the rocks or straight.Serving in the restaurant are large. If you can't finish, ask the waiter for a "doggie bag", so that you can enjoy the food later. Remember, you should always have a tip of about 15%on the table when you leave.参考答案我非常高兴你们各位不久将去美国,与美国人一块学习和工作.无论我们在那儿我们都得吃饭.所以,在情况介绍会的第一个讲座里,我想与各位谈谈美人在餐馆用餐时的一些规矩.在美国餐馆里,通常在点菜之前你会得到一杯饮用自来水.你会发现面包和黄油都是免费的.如果你要咖啡,你可以免费续杯.软饮料是指如可乐那样的甜甜的炭酸化合饮料.硬饮料是指含有酒精的饮料,如:威士忌.可加冰块或不加冰块供应.餐馆里的菜量很足,如果用不完,可请服务员"打包",这样你能呆会儿再吃.记住你得付大约15%小费.餐毕离桌时,放在桌上.【第二题】Crime control is a pretty complex question, the first step, ofcourse, is deterrence to stop people from committing crime in the first place. That involves the economy. Are there enough jobs for everyone? There should be. And social structure, are there enough support system? And so on. When people are convicted, and put in prison, then the goal should be to have reform programs inside prisons. So they want person comes out, they don’t return to a life of crime. If the education program and drug treatment program have been cut, convicted criminals are not being reformed.译文：如何控制犯罪率是一个十分复杂的问题。

历年上海英语翻译考试中级口译英译汉原文真题及参考答案原文A majority of the world’s climate scientists have convinced themselves, and also a lot of laymen, some of whom have political power, that the Earth’s climate is changing; that the change, from humanity’s point of view, is for the worse; and that the cause is human activity, in the form of excessive emissions of greenhouse gases such as carbon dioxide.A minority, though, are sceptical. Some think that recent data suggesting the Earth’s average temperature is rising are explained by natural variations in solar radiation, and that this trend may be coming to an end. Others argue that there is no conclusive evidence that modern temperatures are higher than they used to be.We believe that global warming is a serious threat, and that the world needs to take steps to try to avert it. That is the job of the politicians. But we do not believe that climate change is a certainty. There are no certainties in science. Prevailing theories must be constantly tested against evidence, and more evidence collected, and the theories tested again. That is the job of the scientists.参考答案世界上大部分气候学家已经使他们自己及许多普通民众(包括一些政界人士)确信，地球的气候正处于变化之中;对人类而言，这一变化正日趋严重;罪魁祸首是人类活动，其表现形式为过量排放二氧化碳之类的温室气体。

历年英语翻译中级口译考试试题及答案(完整版)Spot DictationIn America there are no nobles or men of letters, and the common folk mistrust the wealthy; Consequently lawyers formthe highest political class and the most cultivated circle of society. They have therefore nothing to gain by innovation, which adds a conservative interest to their natural taste for public order. If I were asked where I place the American aristocracy, I should reply without hesitation that it is not composed of the rich, who are united together by no commontie, but that it occupies the judicial bench and the bar.When I started researching this topic, I found an interesting website “Legal Reform Now”. As the name suggests, this website is devoted to legal reform and it is definitely concerned about the dominance of lawyers in American government. There I read an article by a political science professor from the university of Wisconsin. One observation the UW article confirms is that the legal profession is the dominant profession of the people re-electto public office. For example, about half our representatives and two-thirds of our senators are lawyers. No otherprofession comes close to having the same the number ofpeople in political office. Effectively, lawyers form our nation’s most powerful organized political constituency in America. Lawyers make our laws and lawyers interpret our laws. When judges are appointed, the American bar association isthe only professional organization that is consulted to rate the fitness of potential judicial appointees. Our nation has been in existence for over 200 years and lawyers have beenthis nation’s aristocracy since its formation. Our system works, but do we really want to have a single profession in charge of our nation? Specifically, do we want to have the legal profession in charge? Next t ime you vote, that’s something to think about.评析：这篇文章是关于律师在美国的地位。

原文：吸烟之危害，可谓大矣，其严重性是不能低估的。

吸烟污染空气，损害健康，使肺癌发病率大大增加。

为了使各国人民关注烟草的盛行及预防吸烟导致的疾病和死亡，世界卫生组织已将每年的5月31日定为世界无烟日。

瘾君子们说，一天饭不吃可以，一个时辰不抽烟就难捱了，不能戒。

只要真正意识到吸烟有百害而无一利，于人于己都是一种祸害，就有可能下决心摆脱烟草的诱惑。

戒烟贵在坚持，坚持下去就是收获。

参考译文Smoking is immensely harmful and its gravity should not be underestimated. Smoking pollutes air, damages health, and increases theodds of lung cancer. To arouse the awareness about the prevalence of tobacco in all the countries and to prevent smoking-induced diseases and deaths, the WHO (World Health Organization) has defined May 31st in every year as World No-Tobacco Day.The tobacco addicts say that smoking is impossible to quit because they could do without meals in a day but would feel tortured without tobacco in two hours. However, when one realizes that smoking is harmful in many ways but beneficial in no way and that it is a curse to others as well as to him, he will be determined to resist the temptation of tobacco. To quit smoking requires persistence and so long as one persists, hell be rewarded.(via sherry)。

英语中级口译翻译真题(英译汉)Why We Must Fire Bad TeachersThe relative decline of American education at the elementary- and high-school levels has long been a national embarrassment as well as a threat to the nation’s future. Once upon a time, American students tested better than any other students in the world. Now, ranked against European schoolchildren, America does about as well as Lithuania, behind at least 10 other nations.For much of this time—roughly the last half century—professional educators believed that if they could only find the right pedagogy, the right method of instruction, all would be well. They tried New Math, open classrooms, Whole Language—but nothing seemed to achieve significant or lasting improvements.Yet in recent years researchers have discovered something that may seem obvious, but for many reasons was overlooked or denied. What really makes a difference, what matters more than the class size or the textbook, the teaching method or the technology, or even the curriculum, is the quality of the teacher. Much of the ability to teach is innate—an ability to inspire young minds as well as control unruly classrooms that some people instinctively possess (and some people definitely do not). Teaching can be taught, to some degree, but not the way many graduate schools of education do it, with a lot of insipid or marginally relevant theorizing and pedagogy. In any case the research shows that within about five years, you can generally tell who is a good teacher and who is not.。
