【答案解析】[听力原文]
W: Yes, sir. You rang?
M: Yes, I wonder if you could bring me another orange juice?
W: Certainly. Would you like anything else?
M: No, thank you. My son in law is supposed to meet me at the airport in London. Do you think he'll be able to find me?
W: I'm sure he will. You don't have to worry about that.
M: Yes. I've never seen my grandson. In fact, I've never seen my son in law, either.
W: I think you'll have a wonderful time in London. It's beautiful. Is this your first time abroad?
M: No. I saw quite a bit of Europe before. Rome, Berlin, Paris, places like that, but never London.
W: Oh, then you have flown before too.
M: No, that was during the Second World War and I went on a troopship.
W: Things are quite different in Europe nowadays.
M: I'm sure they are. I'm really anxious to get there.
W: Well, it's 4:00 now and we'll be there at 6:00. Will you be staying long?
M: I plan to stay five weeks. I was a teacher but I'm retired now. My wife is dead so I can go where I want.
W: I think you're going to have a good time. And don't worry about being met. I bet your daughter will be there too.
M: I hope so, but I don't know if she will.
W: I'll go to get your orange juice for you. I'll be back in a minute.
