Hello，同學們好，歡迎來到成都英語培訓——韋沃教育舉辦的企業商務英語培訓系列課程，英語公共演講第十二課，說明性演講。Informative Speech第三小節。 

  本節內容主要有：分享一段《靈光乍現》，選自英美影視演講欣賞。Flash of Genius。

  二、實例分析。Speech Analysis，下面讓我們首先進入這一段演講欣賞。

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，各位同學，歡迎大家來到應用電氣工程課的第一天，我是羅伯特科恩博士，今天我想跟大家談論道德，作為開始，我想不出一份工作或職業中，對道德的理解有工程課這么重要。 

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. 是誰設計出人工心臟膜瓣？是工程師 ；又是誰設計出奧斯維辛集中營的毒氣室？也是工程師，有人負責拯救數百萬條生命，而另一些人幫助殺害了上百萬人。 

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. 現在我不知道，你們最終在生活中會做什么，但我可以保證有一天，你們也會遇到需要做決定的時候，而這個決定不會比在心臟膜瓣，還是毒氣室之間做選擇這么簡單。 

Everything we do in this classroom ultimately comes back to that notion. All right? Grades count too. 我們在教室所做的所有事情，最終都會回到那個概念，對不對？當然分數也很重要。 

  好了，下面讓我們來看一看這一段話的實例分析。 

首先，開頭簡潔，表示歡迎。A brief introduction and showing welcome at the beginning. 

其次，簡單的自我介紹，以及說明演講主題。Brief self introduction and purpose of the speech.

再者，使用夸張來強調主題的重要性。 Using exaggeration to emphasize the subject. 

  第二部分，列出根據來證明主題。List evidence to prove the subject. 

設置問題引起聽眾的思考。Ask questions to encourage students to think. 

通過設置與主題相關的、相同的答案的不同問題，更加有力地強調了主題。Design questions with the same answer related to the subject to emphasize it again in a powerful way. 

下面一部分，將話題內容與聽眾的實際生活相聯系。Link the subject with audience's real life.

設計情景鼓勵聽眾思考。Set situations to encourage audience thinking.
