Unit 3 Science versus nature一、阅读理解。It may help you to know that there is no such thing as a perfect speech. At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, dont worry about them. Just continue as if nothing happened.Even if you do make an obvious mistake during a speech, that doesnt really matter. If you have ever listened to Martin Luther Kings famous speech I Have a Dream, you may notice that he stumbles (结巴)over his words twice during the speech. Most likely, however, you dont remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making.People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of munication. They feel the listeners are like judges in an ice-skating petition. But, in fact, the listeners are not looking for a perfect performance. They are looking for a well-thought-out speech that expresses the speakers ideas clearly and directly. Sometimes a mistake or two can actually increase a speakers attractiveness by making him more human.As you work on your speech, dont worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.1.The underlined part in the first paragraph means that no one will .A.be smarter than youB. know what you are talking aboutC.do better than youD. notice your mistakes2.You dont remember obvious mistakes in a speech because .A. you find the way of speech-making more importantB. you dont fully understand the speechC. you dont know what the speaker plans to sayD. your attention is on the content3.From the last two paragraphs, the author means that .A. giving a speech is like giving a performanceB. the listeners should pay more attention to how a speech is madeC.one or two mistakes in a speech may not be bad。D. the more mistakes a speaker makes, the more attractive he will be4.What would be the best title for the passage?A.
