1、Presenting a speech（做演讲）Of all human creations, language may be the most remarkable. Through 在人类所有的创造中，语言也许是影响最为深远的。我们用语言language we share experience, formulate values, exchange ideas, transmit 来分享经验，表达 (传递？ )价值观，交换想法，传播知识，knowledge, and sustain culture. Indeed, language is vital to think itself. 传承

2、文化。事实上，对语言本身的思考也是至关重要的。Contrary to popular belief, language | does not simply mirror reality but also helps to create our sense of reality by giving meaning to events. 和通常所认为的不同的是，语言并不只是简单地反映现实，语言在具体描述事件的时候也在帮助我们建立对现实的感知。语序的调整。Good speakers have respect for language and know how it works. Words are

3、the tools of a speaker s craft. They have special uses, just like the tools of any other profession. As a speaker, you should be aware of the meaning of words and know how to use language accurately, clearly,vividly,and appropriately. 好的演讲者对语言很重视， 也知道如何让它发挥更好的效果。词语是演讲者演讲的重要“武器”，具有特殊的用途，这和任何其他的工作技艺没什

4、么两样。作为演讲者，必须知道词语的具体含义，也要懂得如何做到用词准确、清晰、生动、适当。Using language accurately is as vital to a speaker as using numbers accurately to a accountant. Never use a word unless you are sure of its meaning. If you are not sure, look up the word in the dictionary. As you prepare your speeches, ask yourself constan

5、tly, “What do I really want to say? What do I really mean? ” Choose words that are precise and accurate. 演讲者准确地使用语言和会计准确使用数字是一样重要的。确定词意后再措词。如果不确定，请先查词典。当你在准备演讲的时候，要不断地问自己：“我到底要说什么？我到底想表达什么意思？”用词一定要精准。Using language clearly allows lix;=steners to grasp your meaning immediately. You can ensure this by

6、 using familiar words （that are known to the average person and require no specialized background ）; by choosing concrete words in preference to more abstract ones, and by eliminating verbal clutter. 用词清晰可以让听众迅速理解你的意思（抓到你的点）。要做到这一点，就要尽量使用一般人都熟悉的不需要专业知识就能懂的词语；多用具象词汇少用抽象词汇；还有要减少口误。Using language vivid

7、ly helps bring your speech to life. One way (to make your speech vivid)|is through imagery ，or the creation of word pictures. You can develop imagery by using concrete language, simile, and metaphor. Simile is an explicit comparison between things （that are essentially different yet have something i

8、n common）; it always contains the words “like”or “as”. Metaphor is an implicit 精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 1 页，共 20 页 - - - - - - - - - - comparison between things that are different yet have something in common; it does not contain the words “like” or “as”.

9、生动地用词能让演讲鲜活起来！比喻，这种能产生文字图像的修辞，可以使演讲达到生动的效果。比喻要用具象的语言，分为明喻和隐喻。明喻是指在本质上有区别但仍然有相同点的事物之间做一个明确的比较，一般句中会含有“像”或“似” 。隐喻则是一种隐藏的比较，不会出现like 和 as 这些连接词。Another way to make your speeches vivid is by exploiting the rhythm of language. Four devices for creating rhythm are parallelism, repetition, alliteration, an

10、d antithesis. Parallelism is the similar arrangement of a pair or series of related words, phrases, or sentences. Repetition is the use of the same word or set of words at the beginning or end of successive clauses or sentences. Alliteration comes from repeating the initial constant sounds of close

11、or adjoining words. Antithesis is the juxtaposition of contrasting ideas, usually in parallel structure. 我们还可以充分利用语言的节奏感使演讲更加生动活泼。具体有以下四种方式排比，反复，押头韵和对偶。 排比是指把一组或一系列相关的字词句以相似结构排列起来。反复是指在连续几个从句或句子的开头或结尾处使用相同的词和词组。押头韵则是通过重复相邻之间单词首个辅音实现的。对偶通常是用平行的结构将相反的想法并列在一起。Using language appropriately means adapting

12、 to the particular occasion, audience, and topic at hand. It also means developing your own language style instead of trying to copy someone else s. If your language is appropriate in all respects, your speech is much more likely to succeed. 用语恰当意味着遣词造句要与特定的场合，观众以及谈论的话题相适应。 这也意味着你得建立自己的语言风格， 不能简单抄袭他

13、人。 如果使用的语言与各方面都很契合，那么演讲就更有可能取得成功。Good speeches are not composed of hot air and unfounded assertions. They need strong supporting materials to bolster the speaker s point of view.In fact, the skillful use of supporting materials often makes the difference between a good speech and a poor one.The thre

14、e basic types of supporting materials are examples,statistics and testimony. 好的演讲不能是空话连篇， 也不能是一些毫无根据的论断； 而是需要有力的论据来支持演讲者的观点。 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。论据有以下三种基本形式：例子，统计资料，引用。In the course of a speech you may use brief examplesspecific instances referred to in passingand sometimes you may want to gi

15、ve several brief examples in a row to create a stronger impression. Extended examplesoften called illustrations, narrations, or anecdotes are longer and more detailed.Hypothetical examples describe imagery situations and can be quite effective for relating ideas to the audience. All three kinds of e

16、xamples help to clarify ideas, to reinforce ideas, or to personalize ideas. To be more effective, though, they should be vivid and richly 精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 2 页，共 20 页 - - - - - - - - - - textured. 在演讲时可以简单举例即附带地提及几个具体的例子有时也需要接二连三举例来加深印象。 延伸举例也叫解释、 叙

17、述或轶事更长更详尽。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。 这三种不同的例子都有助于演讲者清晰地表达观点，强调观点并使之打上演讲者的烙印。当然，要想演讲效果更好，演讲本身必须生动且结构丰富！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. Above all, you should understand your st

18、atistics and use them fairly. Numbers can easily be manipulated and distorted. Make sure that your figures are representative of what they claim to measure,that you use statistical measures correctly, and that you take statistics only from reliable sources. 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

19、能更好地理解其中的意义。最重要的是， 演讲者必须理解这些统计资料并恰当使用。 数字很容易被篡改、 误报，因此必须确保自己所使用的数据不是张冠李戴的； 必须确保自己使用的统计措施是正确的；必须确保自己的统计资料来源是可靠的。Testimony is especially helpful for student speakers, because they are seldom recognized as expects on their speech topics. Citing the views of people（ who are experts） is a good way to mak

20、e your ideas more credible. When you include testimony in a speech, you can either quote someone verbatim or paraphrase their words. As with statistics, there are guidelines for using testimony.Be sure to quote or paraphrase accurately and to cite qualified unbiased sources. If the source is not gen

21、erally known to your audience, be certain to establish his or her credentials. 引用他人观点看法对学生演讲者来说尤其有用，因为学生很少会被视为他们演讲相关主题方面的专家。 引用专家的观点可以让你的想法更可信。引用的时候， 既可以逐字摘抄也可以自己总结一下。和统计资料一样， 引用也有原则可循引用摘抄准确， 来源合格无偏见。 如果观众对引用来源不太熟悉， 一定要（想办法）取得他们的信任。The impact of a speech is strongly affected by how the speech is del

22、ivered. You cannot make a speech without having something to say. But having something to say is not enough.You must also know how to say it.Good delivery does not call attention to itself.It conveys the speaker s ideas clearly, interestingly, and without distracting the audience. 演讲的效果如何很大程度上取决于演讲是

23、怎么做的。无话可说做不好演讲， 但要做好演讲， 仅仅有话可说也是远远不够的，还要知道如何说话才行。 好的演讲不是要唤起观众对演讲本身的注意，而是要向观众清晰有趣地传递演讲者的想法，同时还要有观众聚精会神地聆听。There are four basic methods of delivering a speech: reading verbatim from a manuscript, reciting a memorized text, speaking with PowerPoint, and speaking extemporaneously, or impromptu. The last

24、 of these speaking extemporaneously is the method (you probably will use for classroom speeches and for most speeches 精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 3 页，共 20 页 - - - - - - - - - - outside the classroom). When speaking extemporaneously, you will have only a brief

25、 set of notes or a speaking outline. Speaking with PowerPoint is widely used now and very effective indeed. 演讲有四种最基本的方法： 照本宣科式； 背诵式； ppt 辅助演讲式和即兴演讲式。最后一项即兴演讲是我们在课堂演讲和大部分课外演讲中都要用到的方法.即兴演讲时，我们手上只有简单的笔记或演讲提纲。现在，用 ppt 辅助演讲十分普遍，效果显著。Certainly there are other factors you should consider, such as personal

26、appearance, bodily action, gestures, eye contact, volume, pauses and so on. By paying enough attention to what is mentioned above, you may present an effective speech. 当然还要考虑其他因素譬如演讲者的个人形象，肢体语言， 眼神交流， 声音的抑扬顿挫等等。尽量注意上述问题，演讲就会成功！Unit 2 Energy in Transition 能源转型The era of cheap and convenient sources o

27、f energy is coming to an end. A transition to more expensive but less polluting sources must now be managed. 能源资源价格低廉、 使用便捷的时代已经过去了，目前应向尽管价格较高、 但污染较小的资源转变。John P . HoldrenUnderstanding this transition requires a look at the two-sided connection between energy and human well-being. Energy contributes

28、 positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. But the costs of energy including not only the money and other resources devoted to obtaining and exploiting it but also environmental and sociopoliti

29、cal impacts detract from well-being. 要了解这一转变， 首先需要考察一下能源和人类幸福的双重关系。能源为人类提供了诸如取暖、照明等消费服务的同时，也为经济生产活动提供必要投入，从这个意义上讲， 能源为人类幸福做出了积极贡献。然而，人类为利用能源所付出的代价却削弱了能源为其带来的利益，这种代价不仅包括为获取和利用能源所投入的资金和其他资源， 而且包含了能源开发和利用所产生的环境影响和社会政治影响。For most of human history, the dominant concerns about energy have centered on the

30、benefit side of the energy well-being equation. Inadequacy of energy resources or (more often) of the technologies and organizations for harvesting, converting, and distributing those resources has meant insufficient energy benefits and hence inconvenience, deprivation and constraint s on growth. Th

31、e 1970s, then, represented a turning point. After decades of constancy or decline in monetary costs and of relegation of environmental and sociopolitical costs to secondary status energy was seen to be getting costlier in all respects. It began to be plausible that excessive energy costs could pose

32、threats on a par with those of insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits. 人类历史发展长河中， 人们主要关心的是能源和人类安康等式中有利的一面。精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 4 页，共 20 页 - - - - - - -

33、- - - 能源资源不足或者 （更经常）开采、加工和分配这些资源所需技术和机构的不足，会影响能源为人类带来的利益， 对人类也就意味着不方便、 损失以及对增长的各种限制。到了 20 世纪 70 年代，出现了一个转折点。此前的几十年中，能源的资金成本一直保持稳定， 甚至有所下降， 而且，其所牵扯的环境成本和社会政治成本一直处于次要地位。 但是 20 世纪 70 年代开始，开发和利用能源的多方成本均显著增长。人们自然有理由认为： 高昂的能源成本所带来的威胁已同能源供应不足所产生的威胁不相上下。 同时，也有人担心， 依靠扩大能源资源增加供应所需付出的代价，也许大于其所带来的利益。The crucial

34、 question at the beginning of the 1990s is whether the trend that began in the 1970 s will prove to be temporary or permanent. Is the era of cheap energy really over, or will a combination of new resources, new technology and changing geopolitics bring it back? One key determinant of the answer is t

35、he staggering scale of energy demand brought forth by 100 years of unprecedented population growth, coupled with an equally remarkable growth in per capita demand of industrial energy forms. It entailed the use of dirty coal as well as clean; undersea oil as well as terrestrial; deep gas as well as

36、shallow; mediocre hydroelectric sites as well as good ones; and deforestation as well as sustainable fuelwood harvesting. 20 世纪 90年代初期人们关注的焦点在于，这种始于70 年代的能源发展趋势是暂时的还是长远的。 廉价能源时代是真正一去不复返， 还是通过开发新能源、应用新技术、 改革地缘政治秩序等措施， 有可能重登历史舞台？回答这个问题的一个关键因素是过去100 年以来因人口空前增长带来的令人瞠目的能源需求以及同样使人无所应对的人均工业能源需求。急剧增长的能源需求使得

37、人类对能源的使用无所不用其极： 不管是清洁煤炭还是劣质煤炭 （或 “无矸煤还是有矸煤”） ，见煤就挖；无论是陆上石油还是海底石油，深层气还是浅层气，见油气就采；水电站建设不论适宜与否， 见水就上； 一边绿化造林以求薪材可持续发展，一边却砍树毁林。Except for the huge pool of oil underlying the Middle East, the cheapest oil and gas are already gone. Even if a few more giant oil fields are discovered, they will make little

38、difference against consumption on todays scale. Oil and gas will have to come increasingly, for most countries, from deeper in the earth and from imports whose reliability and affordability cannot be guaranteed. .除了中东地区蕴藏着巨大的石油资源，地球上廉价的油气资源已经不复存在了。即使偶尔找到几个大的油田，同当今巨大的能源消耗相比，也是杯水车薪。对于大多数国家来说， 油气资源越来越多

39、地依赖进口， 且不说进口油气资源的可靠性无法得到保障，其对进口国的支付能力也是一个考验。There are a variety of other energy resources that are more abundant than oil and gas. Coal, solar energy, and fission and fusion fuels are the most important ones. But they all require elaborate and expensive transformation into electricity or liquid fuel

40、s in order to meet societys needs. None has very good prospects for delivering large quantities of electricity at costs comparable to those of the cheap coal-fired and hydropower plants of the 1960s. It appears, then, that expensive energy is a permanent condition, even without allowing for its envi

41、ronmental costs. .诚然，其他许多资源的储量大于石油和天然气，最重要的有煤、太阳能、聚变裂变燃料等。 但是这些能源转化成电力或液体燃料，以满足社会需求， 需要经精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 5 页，共 20 页 - - - - - - - - - - 过技术复杂、 成本昂贵的转化过程。 同 20 世纪 60 年代成本低廉的燃煤火电站和水力发电站相比，仅从成本考虑，以上各种资源用于大规模发电的可能性极小。因此， 即使不考虑能源开采的环境成本， 能源价格居高不下已成无可改变的

42、定局。The capacity of the environment to absorb the effluents and other impacts of energy technologies is itself a finite resource. The finitude is manifested in two basic types of environmental costs. External costs are those imposed by environmental disruptions on society but not reflected in the mon

43、etary accounts of the buyers and sellers of the energy. “Internalized costs” are increases in monetary costs imposed by measures, such as pollution-control devices, aimed at reducing the external costs. .环境吸纳由于能源利用而产生的废弃物和其他影响的能力本身也是有限度的，表现在两方面的环境成本上。所谓“外延成本”即由于环境遭到破坏对社会造成的影响，但尚未反映到能源买卖双方的交易价格上；所谓“内

44、涵成本”即为降低外延成本而采取的各种措施 （如污染防治措施） 所引起的货币成本的增长。 Both types of environmental costs have been rising for several reasons. First, the declining quality of fuel deposits and energy-conversion sites to which society must now turn means more material must be moved or processed, bigger facilities must be const

45、ructed and longer distances must be traversed. Second, the growing magnitude of effluents from energy systems has led to saturation of the environments capacity to absorb such effluents without disruption. Third, the monetary costs of controlling pollution tend to increase with the percentage of pol

46、lutants removed. .两种环境成本均一直呈增长趋势，原因是多方面的。首先，社会发展所依赖的燃料矿藏和加工地质量下降， 必然要求矿物运输和加工的数量增加、 设施扩大、运输距离延长。 第二，能源利用所产生的废弃物不断增加，使得环境自我净化能力达到了极限。 第三，污染防治所需的资金成本亦将随着消除污染物比例的提高而提高。Despite these expenditures, the remaining uninternalized environmental costs have been substantial and in many cases are growing. Those

47、 of greatest concern are the risk of death or disease as a result of emissions or accidents at energy facilities and the impact of energy supplied on the global ecosystem and on international relations. .尽管代价高昂，尚未内化的环境成本一直居高不下，并在许多情形下呈增长趋势，其中最引人关注的是由能源设施排放废物或发生事故所带来的死亡和疾病，以及由于能源供应对全球生态系统和国际关系造成的影响。T

48、he impacts of energy technologies on public health and safety are difficult to pin down with much confidence. In the case of air pollution from fossil fuels, in which the dominant threat to public health is thought to be particulates formed from sulfur dioxide emissions, a consensus on the number of

49、 deaths caused by exposure has proved impossible. Widely differing estimates result from different assumptions about fuel compositions, air pollution control technology, power-plant sitting in relation to population distribution, meteorological conditions affecting sulfate formation, and, above all,

50、 the relation between sulfate concentrations and disease. .能源技术对于大众健康和安全所造成的影响难以确定。以矿物燃料造成的空气污染为例，一般认为其对大众健康的主要危害是由排放的二氧化硫形成的微粒，但接触这种污染空气究竟会导致多少人死亡，却无法取得一致意见。 各种估算数据千差万别， 原因在于对以下各种因素的分析各不相同，比如燃料构成、 空精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 6 页，共 20 页 - - - - - - - - - - 气
