视译练习Sight InterpretationParagraph 1:On October 15,2007, the Royal Swedish Academy of Sciences has decided to award the Prize in Economic Sciences in Memory of Alfred Nobel 2007 jointly to Leonid Hurwicz (Regents Professor Emeritus of Economics at University of Minnesota), Eric S. Maskin (Professor of Social Science, Institute for Advanced Study, Princeton University) and Roger B. Myerson (Distinguished Service Professor at Professor at University of Chicago) “for having laid the foundations of mechanism design theory”. The Prize amount SEK10 million, will be shard equally among the Laureates.2007年10月15日，瑞典皇家科学院决定将2007年度诺贝尔经济学奖授予：列奥尼德·赫维茨（美国明尼苏达大学经济系杰出荣誉教授）、埃里克·S·马斯金（美国普林斯顿进修学院社会科学教授）、罗杰·B·迈尔森（美国芝加哥大学杰出贡献教授）“以表彰他们对于建立机制设计理论所做的贡献”。
奖金总额1,000万瑞典克朗，将由获奖者平均分享。
The Royal Swedish Academy of Sciences, founded in 1739, is an independent organization whose overall objective is to promote the sciences and strengthen their influence on society.瑞典皇家科学院成立于1739年，是一个旨在推动科学发展以及加强科学在社会中影响的独立组织。
2013-1In an essay entitled “Making It in America”, the author Adam Davidson relates a joke from cotton country about just how much a modern textile mill has been automated: The average mill has only two employees today,” a man and a dog. The man is there to feed the dog and the dog is there to keep the man away from the machines.”在一篇名为(entitled)《成功（make it）在美国》的文章中，作者亚当·戴维森讲述(relate)了这样一个源自棉花出产国的笑话，笑话是关于现代纺织(textile)作坊(mill)已高度自动化(automate)：现如今，一家普通作坊里只有两名员工，“一个人和一条狗，人在作坊里是为了喂狗，狗在作坊里是为了使人远离(away from)机器。
”Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is also because of the advances in both globalization and the information technology revolution, which are more rapidly than ever replacing labor with machines or foreign workers.最近出现了很多(a number of)类似戴维森所写的文章，它们都表明了这样一种看法(make a point)：之所以失业人数(unemployment)居高难下(stubbornly high)和中产阶级(middle-class)收入(income)持续下降，原因是全球化与信息技术革命已经取得了诸多进步，它们使得机器和国外员工在取代(replace .. with)本国劳动力(labor)方面比以往任何时候都要迅速。
6. the statement that oil originated in the sea is confirmed by a glance at a map showing that chief oilfields of the world；very few of them are far distant from the oceans of today.石油原于大海的这种观点是被人们所认可的，你要看一眼世界主要油井的分布图就一目了然了，几乎没有远离现在海洋的油井。
7. the rocks in which oil is found are of marine origin too.石油存在处的岩石也都有海洋的渊源。
8. A very common sedimentary rock is called shale，which is a soft rock and was obviously formed by being deposited on the sea bed. And where there is shale there is likely to be oil.一块极普通的沉积岩叫页岩，这种页岩质地松软，很明显是通过海底沉积作用形成的。
有页岩的地方，极有可能有石油。
9. the drill may just miss the oil although it is near；on the other hand，it may strike oil at a fairly high level.有时石油虽就在附近，但因为没钻准地儿，结果还是一无所获。
有时呢，就这么一钻，石油就喷出好高好高。
10. when the crude oil is obtained from the field，it is taken to the refineries. Gas that comes off the oil later is condensed.从油田获得的原油要被送到炼油厂进行处理。

Unit 1A题1 Through language we share experience, formulate values, exchange ideas, transmit knowledge, and sustain culture.我们用语言来分享经验，传递价值观，交换想法，传播知识，传承文化。
2 Metaphor is an implicit comparison between things that are different yet have something in common.隐喻是一种隐含的比较，不同的事物却有共同的东西。
3 In fact, the skillful use of supporting materials often makes the difference between a good speech and a poor one.事实上，能否有技巧地使用论据会造成演讲效果的天壤之别。
4 To be more effective, though, they should be vivid and richly textured.当然，要想演讲效果更好，演讲本身必须生动且结构丰富。
5 Extended examples—often called illustrations, narrations, or anecdotes—are longer and more detailed.延伸举例——也叫解释、叙述或轶事——更长更详尽。
6 Hypothetical examples describe imagery situations and can be quite effective for relating ideas to the audience.假设举例描述的是想象的情景，能够很好地把想法传达给观众。
7 Statistics can be extremely helpful in conveying your message, as long as you use them sparingly and explain them so they are meaningful to your audience. 统计资料非常有助于演讲者传递信息，因为当演讲者适量地运用这些资料并加以解释时，听众就能更好地理解其中的意义。
