听力原文：M: Hello? W: Hello, Alan. This is Lucy. I'm in trouble. M: What happened? W: I'm afraid I won't be on the flight this afternoon. I got blocked in a traffic jam on the way to the airport and, by the time I got here there were no seats left. The airline had oversold the seats. I don't know what to do. M: Well, the best thing to do is to get a seat on another airline. You could ask your airline to arrange for it. There might be a later flight tonight, or a flight tomorrow morning. W: Well, if I have to stay overnight at the airport, I don't think I have enough cash to pay bills. I left my credit card at home. M: Oh, that's unlucky. W: So, what do you think I should do? M: Well, the only thing to do is—er—for us to pay for your room and you can pay us back later. I'll give them my credit card number and they'll charge it to me. W: Thank you so much, Alan. M: It's a pleasure. (20)
