听力原文：W: I didn't realize that John and Teresa were going to get married so soon. Did you? M: No, I didn't. I know they were engaged, of course. But I thought they'd wait until next year. W: So did I. That's why I was so surprised when they announced that the wedding would be next month. M: Anyway, they're well-suited for each other. I'm sure Teresa will make John a very good wife. W: Yes, and John will make Teresa a very good husband. I hear John asked you to make a speech at the reception. M: That's right. I'm a bit nervous about it, though. I've never made a speech before. W: Oh, I'm sure you'll do a good job, Mark. I'll be there to encourage you. M: Well, if you want to encourage me, promise that you won't laugh. W: I promise. Well, I've got to see about a new dress for the wedding. See you, Mark. M: Ok, Mary. (20)
