第二节 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余项。

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.  __71__ Why? Because the listeners do not know what the speaker plans to say.  72    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, don’t worry about them. Just continue as if nothing happened.

    73     If you have ever listened to Martin Luther King’s famous speech--- “I have a Dream”, you may notice that he stumbles (结巴) over his words twice during the speech.     74    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 communication. They feel the listeners are like judges in an ice-skating competition.    75  They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human.

As you work on your speech, don’t worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.

A.They only figure out what you are trying to say.

B.Most likely, however, you don’t remember.

C.But, in fact, the listeners are not looking for a perfect performer.

D.Even if you do make an obvious mistake during a speech, that doesn’t really matter.E.Quite often, however, you just laugh his small mistakes off.

F.Fortunately, such moments are usually not obvious to the listeners.

G.They hear only what the speaker does say.
