研究生英语阅读教程(基础级3版)课文答案翻译

Lesson 1 II. Translation Put the following passages into Chinese. 1. For English is a killer. It is English that has killed off Cumbric, Cornish, Norn and Manx. There are still parts of these islands where sizeable communities speak languages that were there before English. Yet English is everywhere in everyday use and understood by all or virtually all, constituting such a threat to the three remaining Celtic languages, Irish, Scottish Gaelic, and Welsh... that their long-term future must be considered... very greatly at risk. 因为英语是个杀手。正是英语造成了凯尔特语、康沃尔语、诺恩语和马恩语等语言的消亡。这些岛上的分地区依然还有很多社区的人使用在英语到来之前就已存在的语言。然而,英语在日常生活中无处不在。所有的人或几乎所有的人都懂英语。英语对仅存的三种凯尔特语——爱尔兰语、苏格兰盖尔语及威尔士语的威胁是如此之大,人们一定认为它们遥远的未来是岌岌可危的。 2. He also associated such policies with a prejudice which he calls linguisticism (a condition parallel to racism and sexism). As Phillipson sees it, leading institutions and individuals within the predominantly "white" English-speaking world, have (by design or default) encouraged or at least tolerated—and certainly have not opposed—the hegemonic spread of English, a spread which began some three centuries ago as economic and colonial expansion. 同时,他认为这些政策和他称之为语言歧视(与种族歧视、性别歧视等类似)的偏见密切相关。在菲利普森看来,在以白人英语为主导的世界里,主要的机构和个人(有意或无意地)鼓励或者至少是容忍了(肯定没有反对)英语霸权主义式的传播,这种传播始于三个世纪之前的经济及殖民扩张。 3.By and large, we now view them as more or less benign, and often talk with admiration and appreciation about the cultures associated with them and what they have given to the world. And it is fairly safe to do this, because none of them now poses much of a threat. 总的来说,我们现在或多或少地把这些语言看作有利的语言。在谈到与之相关的文化及其为世界所做的贡献时,我们常怀有崇敬与赞赏,而且这样做是很安全的,因为这些语言现在已不会构成什么大的威胁。 4. Yet many people see English as a blessing. Let me leave aside here the obvious advantages possessed by any world language, such as a large communicative network, a strong literary and media complex, and a powerful cultural and educational apparatus. 然而,许多人把英语看成是一件幸事。在此,我暂且不谈世界语言所具有的明显优势,例如庞大的交流网络、发达的文字与传媒体系以及强大的文化教育设施。 5. English-speaking South Africans of British descent were not particularly strong in opposing the apartheid regime, and the black opposition, whose members had many languages, was at first weak and disorganized. 讲英语的南非英国后裔并不强烈反对种族隔离政权,而黑人反对力量,其成员讲多种语言,在初期软弱无力且缺乏组织。 6. Such symbolism suggests that the users of the world's lingua franca should seek to benefit as fully as possible from the blessing and as far as possible avoid invoking the curse. 这一象征表明这种世界通用语的使用者应充分发掘这一幸事为我们带来的好处,同时尽能避免招来灾难。

2007考研英语阅读理解真题解析第二篇“智商测验”

2007 Text 2 For the past several years, the Sunday newspaper supplement Parade has featured a column called “Ask Marilyn.” People are invited to query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228 – the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks. So it is a bit confusing when vos Savant fields such queries from the average Joe (whose IQ is 100) as, What’s the difference between love and fondness? Or what is the nature of luck and coincidence?①It’s not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers. 在过去的几年,《星期日报》的增刊《漫步》开设了一个名为“询问玛丽琳”的专栏。人们被邀请去询问 玛丽琳?沃斯?萨文特,玛丽琳?沃斯?萨文特在10岁时测试的智力水平达到别人23岁时的水平,这使得她的智商高达228――是有记录的最高水平。智商测试要求你完成口头和视觉分析,要求你在纸张被折叠、剪切后想象它的形状,要求你推论数字的顺序,还有其他类似的项目。所以,当沃斯?萨文特面对普通人(智商为100)提出的像“热爱与喜爱之间的区别是什么?”或者“运气与巧合的特征是什么?”这样的问题时,她感到有点困惑。设想物体、判断数字模式的能力如何使一个人能够回答难倒了一些最杰出的诗人和哲学 家的问题,这可并不那么显而易见。 mental adj.精神的, 智力的 verbal adj.口头的 【记】verb(言语),+al(形容词后缀)=口头的;nonverbal:不用语言的 analogy n.类似, 类推 【习】have an analogy to/with具有与...相似之处;by analogy用类推法 【例】No analogy exists between them. 两者毫无相似之处。 envision vt.想象, 预想 numerical adj.数字的, 用数表示的 fondness n.爱好, 溺爱 coincidence n.一致, 相合, 同时发生或同时存在(尤指偶然)的事 【巧】co(together)+ incidence(incident)=coincidence:两个小的事情同时发生,“巧合”【例】What a coincidence.多巧啊。 elude v.躲避 1、It's not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers. 【译文】有些问题连一些最杰出的诗人和哲学家都难以回答,但是想象物体和计算数字模式的能力却能使 人找出答案,其中原因并不为人所知。 【析句】这是一个简单句,It只是形式主语,真正的主语是how引导的主语从句。而在主语从句中,主 语是the capacity to visualize objects and to figure out numerical patterns,谓语是suits,宾语是one,to answer questions是宾语补足语,而questions后又跟了一个定语从句。 【讲词】visualize意为"想象",是imagine的同义词。例如:He had a hard time to visualize the scene as it was described.(他难以设想所描绘的场景。) elude表示"躲避",也可表示"理解不了,想不起来"。根据句中的意思,可以译为"回答不了"。例如:The answer to this question eluded me for a long time, perhaps because it was so simple.(这个

Lesson 1 1. Yesterday’s terrorism darkened, marked and forever altered the way Americans live their lives. 昨日发生的恐怖主义活动使美国人的生活暗淡无光,在他们的生活中留下了印迹,并永远地改变了他们的生活。 2. “We are going to have to learn what a lot of other countries have gone through: to manage fear at a cultural and national level,” said Charles Figley, a professor of trauma psychology at Florida State University. “We’re getting a lesson in the way fear works.” 佛罗里达州立大学创伤心理学教授查尔斯?费格里说:“我们得学一学其它许多国家曾经经历过的东西,那就是从文化上和在全国范围内来应对恐惧。”他还说:“我们正在体验恐惧是怎样起作用的。” 3. In a country long proud and even boastful of its openness—a country where an ordinary citizen can stroll through the U.S. Capitol unescorted—the terrorist attacks are likely to force Americans to a lot of that. Metal detectors now mark the front door of many government buildings, and security guards are a fixture in the lobby of most large office buildings. 美国是一个一向以开放自豪甚至洋洋得意的国家,在这里,人们可以独自在美国国会大楼中闲庭信步,而现在,恐怖袭击很有可能迫使美国人处处小心,惶惶不可终日。其实我们很大程度上已经是这样了。许多政府大楼的前门装设的金属探测器已然成为一道风景线,大部分的办公大楼里也必备保安。 4. But retaliation carries the risk of setting off a tightening spiral of violence and counterviolence not unlike the Middle East or Northern Ireland. Unlike countries that have had to learn to live with violence,”We are new at this,” said Florida’s Dr. Figley, who heads a project that has trained trauma teams in Yugoslavia.”My fear is we will overreach and make things worse rather than better by retribution, revenge, racism and marginalizing ethnic groups.” 报复有很大的危险,会引发和在中东及北爱尔兰一样的紧张的暴力和反暴力的恶性攀升。与那些不得不在暴力中学习如何生存的国家不同,“我们是新手,”曾在南斯拉夫训练过创伤急救队的项目负责人费格里博士说,“我所担心的是惩罚、报复、种族主义和排斥少数民族的举动会过于偏激,适得其反。” 5. Fear of terrorism is likely to lead Americans to tolerate more government surveillance—such as overhead video cameras at sporting events—than they have to date. “It’s very likely in the wake of today’s events that we’re going to see a greater acceptance on the public’s part—and on the court’s part—to approve certain kinds of police tactics,” said William Stuntz, a Harvard Low School professor. 对于恐怖主义的恐惧会使美国人接受比现在更多的来自政府的监控,例如在运动竞赛场上高架的摄象机。哈佛大学法学院教授威廉姆斯?斯汤资说,“经过目前前这些事件,我们将发现,无论是公众,还是法庭,都会在更大程度上接受某些警察的策略。” Lesson 5 戴维先到一步,事后他气愤地向我发难说当他告诉领班准备和谁一起吃饭时,领班的语气骤然逆转。一瞬间就从“这是个什么人?”变成“这边有请,先生。”当我们赶到时,拍照的人已经在饭店外忙个不停了。戴维开始嘲笑我是伦敦这家高级饭店里的知名人物。这时,我俩向屋内望去并同时看到了我们的偶像。
