听力原文：M: I wonder if you can help me. W: I'd be glad to. M: I've just arrived and I'm not used to the time difference here. I don't want to be a late sleeper because I like to take a walk in the early morning. W: I see. You're from the United States, aren't you? M: Yes, I'm from New York. W: Beijing time is 13 hours ahead of New York. M: Oh, I see. That's very kind of you to give me the information. I'd have no idea about it without your help. W: My pleasure. You must be tired after a long flight. So you'd better have a good rest. It takes time to recover from a jetlag. M: That's very considerate of you. But would you please wake me up at 5 Beijing Time tomorrow morning? W: Yes, sir. No problem. (16)
