     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, the 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, don't worry about them, just continue as if nothing happened.

     Even if you do make an obvious mistake during a speech, that don't really matter. If you have ever listened

to Martin Luther King's famous speech -"I have a dream", you may notice that he stumbles (结巴) his words

twice during the speech. Most likely, however, you don't 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 mistakes 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. But, in fact, the listeners are not looking

for a perfect performer. They are looking for a well-thought-out speech that express the speaker's 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, don't worry about being imperfect. Once you free your mind of this, you will

find it much easier to give your speech freely.
