Hello，同学们好，欢迎来到成都英语培训——韦沃教育举办的企业商务英语培训系列课程，英语公共演讲第十二课，说明性演讲。Informative Speech第三小节。 

  本节内容主要有：分享一段《灵光乍现》，选自英美影视演讲欣赏。Flash of Genius。

  二、实例分析。Speech Analysis，下面让我们首先进入这一段演讲欣赏。

Good morning, everybody, welcome you all to the first day of applied electrical engineering. My name is Dr. Robert Cohen. l'd like to start by talking to you about ethics. I can't think of a job or a career with the understanding of the ethics more important than engineering. 早上好，各位同学，欢迎大家来到应用电气工程课的第一天，我是罗伯特科恩博士，今天我想跟大家谈论道德，作为开始，我想不出一份工作或职业中，对道德的理解有工程课这么重要。 

Who designed the artificial heart valve? An engineer did that. And who designed the gas chamber at Auschwitz? An engineer did that too. One man who is responsible for helping to save tens of thousands of lives, and another man helped kill millions. 是谁设计出人工心脏膜瓣？是工程师 ；又是谁设计出奥斯维辛集中营的毒气室？也是工程师，有人负责拯救数百万条生命，而另一些人帮助杀害了上百万人。 

Now I don't know what any of you will end up doing in your lives, but I can guarantee you that there will come a day when you have a decision to make. And it won't be as easy as deciding between a heart valve and gas chamber. 现在我不知道，你们最终在生活中会做什么，但我可以保证有一天，你们也会遇到需要做决定的时候，而这个决定不会比在心脏膜瓣，还是毒气室之间做选择这么简单。 

Everything we do in this classroom ultimately comes back to that notion. All right? Grades count too. 我们在教室所做的所有事情，最终都会回到那个概念，对不对？当然分数也很重要。 

  好了，下面让我们来看一看这一段话的实例分析。 

首先，开头简洁，表示欢迎。A brief introduction and showing welcome at the beginning. 

其次，简单的自我介绍，以及说明演讲主题。Brief self introduction and purpose of the speech.

再者，使用夸张来强调主题的重要性。 Using exaggeration to emphasize the subject. 

  第二部分，列出根据来证明主题。List evidence to prove the subject. 

设置问题引起听众的思考。Ask questions to encourage students to think. 

通过设置与主题相关的、相同的答案的不同问题，更加有力地强调了主题。Design questions with the same answer related to the subject to emphasize it again in a powerful way. 

下面一部分，将话题内容与听众的实际生活相联系。Link the subject with audience's real life.

设计情景鼓励听众思考。Set situations to encourage audience thinking.

用具体的例子阐明设计的情景，让听众更容易想象。Specify the setting situations with exact examples to make it easier for audience to imagine. 

最后一个小部分，通过用例子联系现实，将观众带回到演讲主题。Relate the examples to the real world life to bring audience back to the subject.  

并且做一个总结。Make a conclusion. 以好笑的、观众没预料到的话题来结束，留下轻松深刻的印象。Ending with something funny and unexpected to leave a relaxing and a deep impression to audience.
