第一单元? 如何发表演说 斯蒂芬·卢卡斯? ???? 在人类创造的万物中,语言可能是最卓越的一项创造。通过语言,我们可以分享经验、阐明价值观念、交流思想、传播知识、传承文化。确实,语言对于思想本身至关重要。和流行的信仰不同的是:语言并不是简单地反映事实,而是通过对事件意义的思考来帮助人们感悟现实。? ???? 优秀的演说者尊重语言并懂得如何驾驭语言。语言是演说者展示才能的工具,对于他们来说,如同其他职业的工具一样,语言也有特殊的功用。作为一名演说者,你应该意识到话语的意义,并懂得如何准确无误地使用语言,使其表达清楚,趣味横生,恰如其分。? 如同数字对于会计的重要性一样,准确地使用语言对于演说者至关重要。在没有确切知道一个词语的意思之前,千万不要盲目使用。碰到没有把握的词语,一定要查词典追根究底。当你准备演讲之前,一定要不断地问自己:“我究竟想说些什么?我究竟想表达什么样的意思?”因此,对于一篇演讲稿的用词来说,必须准确无误。? 如果语言表达清楚无误,听众就能很快抓住你的意思。鉴于此,演说者应该使用那些对于大多数人来说非常熟悉的词语,这些词语不需要任何专业背景就能够理解;演说者应该使用那些表达具体而不是相对抽象的词语;并且千万不要乱堆砌辞藻,哗众取宠。? 准确生动地使用语言能够使你的演说贴近生活。有一种方法可以使你的语言更加生动形象,那就是通过展开联想或创造语言图示。通过使用表达具体的词语、明喻或者暗喻等手法可以展开想像。明喻是对事物不同之处的比较,不过有些是相同的:它们总是包含“像……一样”或者“如同……一样”这样的连词。暗喻是一种隐性的比喻,它能够把两个形式不同但是有一些相通之处的事物联系在一起,暗喻不包含“像……一样”或者“如同……一样”这样的连词。? 另一种让你的演说生动形象的方法是注重语言的节奏感。有四种修辞格可以让你的语言富有节奏感:排比、重复、头韵和对比。排比是将一组或一系列具有相似结构的词语、短语或者句子排列在一起;重复是在一系列短句或者长句的开头或者结尾使用相同的一句话或者一组词语;头韵是指邻近或者相邻的几个句子中的首个词语的辅音字母相同;对比是将一些意思相反的词语或者句子并列在一起,通常使用排比结构。 恰当地使用语言是指语言的运用要符合特定的场合、特定的观众和特定的主题。同时,恰当地使用语言还意味着演说者要有自己的语言风格,而不是模仿他人的口吻。如果演说者的语言在各个方面都能够做到恰如其分,那么这篇演说成功的机率就会大大提高。??????? 优秀的演说并不是空穴来风、缺乏论据的决断。演说者必须找到强有力的论据来支持其观点。实际上,熟练地使用论据经常是区别一篇优秀演说词和一篇空洞演说词的关键所在。一般来说,通常有三种论据材料:事例、统计数据和证词。? ???????在演说过程中,你可以使用一些简明扼要的例子——比如过去发生的一个很具体的事件——有时候,你可以罗列好几个简明的例子,借此增强听众的印象。扩展性的例子——描述、叙述或者奇闻轶事——通常长一些,但更具体。夸张性的例子描述想像中的情形,这种例子能够将相关的想法有效地传达给听众。这三种例子都能够帮助演说者理清思绪、加强印象或者使演说更加娓娓动听。为了使表达更加富有效果,例子应该生动活泼,丰富多彩。 只要演说者对于统计数据用之得当并且加以解释,这些数据将有助于有效地传达信息,听众也能从统计数据中获益匪浅。最重要的是:演说者应该对统计数据了如指掌,并且运用得恰如其分。由于数据很容易操纵和捏造,因此,对于演说者来说,一定要确保图表没有张冠李戴,并且要确保统计方法正确,数据来源可靠。?

Unit 1 Presenting a Speech Road Building Good morning, everyone. Today I'l l be talking about the relationship between road building and the development of the American economy during the 18th century. About 300 years ago, the United States' economy was growing rapidly, mainly because of a booming trade in two important agricultural products: grain and cotton. Grain output in the eastern part of America increased quickly at that time due to the rapidly growing population and the large number of immigrants from Europe. As a result, the demand for grain almost doubled. For this reason, the trade in grain first developed in this part of the country. At the same time, the road system was gradually built up in order to transport the grain from the rural areas to various cities. The road building clearly helped develop the economy quickly in these areas and in the cities as well. During the same period, farmers in the South could get a large amount of laborers from Africa, and they started to grow cotton. As the cotton output increased, the farmers needed to sell it in other places. As a result, many roads were built to link the rural areas to the cities. At first, this trade of grain and cotton took place along the coast, or near rivers and lakes. It took place there because it was easy and cheap to transport goods from one place to another. Before 1700, it was very expensive to move the goods by road.

His Politeness Is Her Powerlessness Deborah Tannen There are many different kinds of evidence that women and men are judged differently even if they talk the same way. This tendency makes mischief in discussions of women, men and power. If a linguistic strategy is used by a woman, it is seen as powerless; if it is used by a man, it is seen as powerful. Often, the labeling of “women?s language” as “powerless language” reflects the view of wo men?s behavior through the lens of men?s. 他这样说是彬彬有礼,她这样说是低微无能 黛博拉·塔嫩各种各样的证据表明:即使女性和男性说话方式相同,人们对他们的看法还是不同。这种倾向导致有关女性、男性和有无能耐的讨论纷争不断。女性说话讲究方式方法被认为是低微无能,而换成男性则被认为是有能力的表现。视女性的语言为低微无能者的语言常常反映出男性看女性行为的视觉角度。 Because they are not struggling to be one-up, women often find themselves framed as one-down. Any situation is ripe for misinterpretation.This ambiguity accounts for much misinterpretation by experts as well as nonexperts, by which women?s ways of thinking, uttered in a spirit of rapport, are branded powerless.Nowhere is this inherent ambiguity clearer than in a brief comment in a newspaper article in which a couple, both psychologists, were jointly interviewed. The journalist asked them the meaning of “being very polite.” The two experts responded simultaneou sly, giving different answers. The man said, “Subservience.” The woman said, “Sensitivity.” Both experts were right, but each was describing the view of a different gender. 女性不为高人一等而拼搏,往往就被认为是低人一等。在任何情况下都极易发生误会。这也说明了为什么专家和非专家常常把女性以友善语言表述出来的思维方式曲解成低微无能的表现。没有什么能比一家报社刊登的采访片段更能清楚地说明这种根深蒂固的歧义。采访对象是一对心理学家夫妇,当记者问他们“表现得非常有礼貌”的含义时,这两位专家同时给出不同的答案。男性回答说:“服从。”女性回答说:“敏感。”两位专家都是正确的,只不过每个人描述的是不同性别的观点。 Experts and nonexperts alike tend to see anything women do as evidence of powerlessness. The same newspaper article quotes another psychologist as saying, “A man might ask a woman, …Will you please go to the store?? where a woman might say, …Gee, I really need a few things from the store, but I?m so tired.?” The woman?s style is called “covert,” a term suggesting negative qua lities like being “sneaky” and “underhanded.” The reason offered for this is power. The woman doesn?t feel she has the right to ask directly. 专家和非专家都习惯把女性的任何行为看为低微无能的表现。以上同一篇报刊文章援引另一位心理学家的话说:“一个男人会这样问一个女人:…请你去一趟商店好吗??同样的情况下女人会说:…哎,我真的需要从商店买点东西,但是我实在太累了。?” 女性的这种表达方式被称为“隐蔽的”,该词含有“鬼祟”和“秘密”等贬义,而这样表述的原因归咎于一个“权”字,女人觉得她没有权利直接提出要求。 Granted, women have lower status than men in our American society. But this is not necessarily why they prefer not to make outright demands. The explanation for a woman?s indirectness could just as well be her seeking connection. If you get your way as a result of having demanded it, the payoff is satisfying in terms of status: You?re one-up because others are doing as you told them. But if you get your way because others happened to want the same thing, or because they offered freely, the payoff is rapport. You?re neither one-up nor one-down by being

are not criticized for doing so.these differences in the patterns of communication and style of communicating are studied by experts who study the effects of gender on communication.they study these effects in order to understand why misunderstandings occur between men and women in conversation. Often,it’s because their styles and patterns of conversation are so different.it is important that we learn to recognize these differences so that we can learn to communicate better with people of the other gender. 或许正是我们的男女社会观念加深了女人比男人话多的这一模式化印象,甚至导致这些不同沟通方式的出现。如果一个女人真的在别人说话时插嘴,她或许会被认为是话多,或许会为此受到批评。因为我们的文化—还有其他很多文化—如此教导女性:她们如果想要有女人味就必须文静。或许男性文化鼓励男孩和男人支配谈话并且更经常打断谈话,而且健谈和频繁打断话头的男性不会为此受到批评。研究性别对交流所产生的作用的专家们针对沟通模式和沟通风格方面的这些差异进行探究,以便了解在男女对话中为什么会产生误解。误解的产生常常是因为他们的对话风格和方式存在极大的差异。为了能学会更好地和异性交流,我们有必要认识这些差异。 (Unit3)C TO E Using a driving simulator, some US researchers studied the driving of 40 people. Some of them drove while talking on a cell phone, others navigated while drunk, and others drove with no such distractions or impairment. The results showed that there were three accidents in which the drivers were talking on cell phones — all of them involving a rear-ending. The research has found that those talking on the phone while driving are more sluggish. In addition, talking on the cell phone can reduce reaction time by 9 percent in terms of braking and 19 percent in terms of picking up speed after braking. 美国的研究人员使用了一种模拟驾驶器,观察40名志愿者分别在手持手机通话驾驶、酒后驾驶以及专心驾驶的过程。结果显示:共有三名志愿者发生追尾事故,司机当时均在打手机的状态下。研究发现:无论手机是否处于免提状态,司机在通话状态下会放慢车速。此外采取刹车措施的反应速度也会减慢9%,而刹车后加速的速度又会减慢19%。(Unit2) E TO C energy has a dual relationship with human well-being.for most of human history,man has been concerned mainly about the benefit side of the energy-well-being equation thanks to the low costs involved in energy use.however,with the staggering scale of energy demand brought forth by 100 years of unprecedented population growth,coupled with an equally remarkable growth in per ca-pita demand of industrial energy forms,energy entails increasingly higher costs,both external and internalized.on the one hand,energy resources are reducing at an accelerating speed and energy supply requires higher input.on the other hand,the external costs seem more worrisome because energy use poses serious threats to public health and safety,keeps disrupting the global ecosystem,and may trigger large-scale military conflict. 能源和利益有着双重关系。人类历史发展长河中,由于能源成本低廉。人们主要关注能源和人类安康关系中有利的一面。然而、过去一百年以来,人口空前速度增长,引起了能源需求的激增,同时,人均工业能源亦急剧增长,因此能源利用所需成本越来越高;另一方面相比之下、外延成本更加令人忧虑,原因是能源利用严重威胁大众健康和安全,不断破坏生态资源,并可能引起大规模军事冲突。
