单项选择题听力原文：M: Hello, could I speak to Karen, please?
W: Speaking.
M: Hi, Karen, it's Jack.
W: Hello, Jack. What's up?
M: A bunch of us are going to a new Thai restaurant for dinner tonight. How about coming with us?
W: I'd love to, but I have to prepare for my speech. I'll be the main talker in the classroom discussion tomorrow morning.
M: Oh, what a shame, maybe next time.
W: I'm so sorry.
M: Never mind. Are you afraid of making a speech?
W: I'm a little nervous indeed.
M: I hate to get up in front of many people. I often forget what to say and don't know where to put my hands.
W: Oh, it's not so serious as that. Someone might get frozen up for a while before the audience. But when you have made a start, you can carry on with what you've prepared, and your performance won't be too bad.
M: Yes. There is something I should learn from you, you know, self-confidence. By the way, how have you prepared your speech?
W: Not very well, I'm afraid. I didn't write every word of the speech, I just have an outline of about 80 words.
M: Are you sure you can do the presentation well only depending on a rough draft of the main ideas?
W: Yes, almost. You know, the speech is about my personal experience in learning spoken English. I'm going to talk on the most familiar topic to my classmates. I'm not afraid of anything. The key problem is how to compose the speech with a reasonable flow.
M: You're wonderful! I hope you succeed in tomorrow's public speaking.
W: Thanks a lot.
