听力原文：M: Hurry up, Kate. We'll be late. W: I am hurrying. I can't move any faster. M: It's always the same. We can never get anywhere on time. W: Right! I'm ready. Really, David, if you gave me some help around the house, we'd never have to hurry like this. I can't do everything, you know. M: Well, we'd better be off. We're late already. W: Oh, no! It's absolutely pouring. We can't go out in that. We'll be soaked. M: Nonsense! Come on. It's only a shower. It won't last long. W: A shower? That! It's set in for the night. I'm not going out in that. M: Well, you've got your umbrella, haven't you? Use that. And anyway, it's only five minutes to the Johnsons' house. W: It might just as well be five miles in that rain. And I haven't got my umbrella. I left it in the office. M: That wasn't very clever of you, was it? W: Well, we could use your umbrella, I suppose. M: We can't. I left it on the train six weeks ago. W: Oh, David. Really, you are impossible. M: Well, we can't stand here all night. We're late as it is. Let's go. W: I'm not going out in that. And that's final. M: I'd better ring for a taxi then. W: Yes. You'd better, hadn't you? Questions 23 to 25 are based on the conversation you have just heard. 23. Why does Kate refuse to leave the house then? 24. What are Kate and David going to do? 25.
