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。?

Four devices for creating rhythm are parallelism, repetition, alliteration, and 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 or adjoining words. Antithesis is the juxtaposition of

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.
