M: You know I will be the main talker in the classroom discussion tomorrow morning. To tell the truth, I’m really a bit nervous indeed.
W:(13)I hate to get up in front of an audience. I often forget what to say and don’t know where to put my hands.
M: Oh, not so serious as that. Someone might get frozen up for a while before the audience. But when you have made a start, you’ll carry on with what you’ve prepared, and your performance wouldn’t be too bad.
W: Yes. There is something I should learn from you, you know, your self-confidence. When I make a public speech, no matter how fluently I say myself, my brain becomes blank the instant I get onto the platform.(14)But the truth is that when I have confidence, things will be much better. By the way, how have you prepared your speech?
M: Not very well, I’m afraid. I don’t write every word of the speech, just an outline of about 80 words.
W: Are you sure you can do the presentation well only depending on a rough draft of main ideas?
M: Almost. You know, the speech is about my own experience in learning spoken English.(15)I’m going to talk the most familiar topic of my study to my classmates. I’m not afraid of anything. The key problem is how to compose the speech with a reasonable clue.
W: That’s another thing I should learn from you. It seems that I can never make a speech unless I write down every word.
M: Well, we’d better exchange our views together sometime.
W: Wonderful! May you succeed in tomorrow’s public speech.
