听力原文:W: Good morning, sir. What can I help you?
M: I wonder if you could tell me some information about active holidays.
W: Active holidays, sir? Can you tell me exactly what you mean, please?
M: Well, you see, when I go on holiday, I like to take plenty of exercise. I don’t like staying around and doing nothing. I get enough of that in my office. What I mean to say is I’m the sort of men who enjoy swimming, water skiing, that sort of thing. I like anything to do with water and I don’t mind roughing it. I’ve always been used to looking after myself. When I was in the army, I used to get up at five every morning just to see the sunrise.
W: Yes, sir, very interesting. Urn... active holidays, let me see. Oh, yes, what about skin diving, sir? We can offer you a fortnight off the coast of Cornwall, all--including one week skin diving and one week shark-fishing with the local fishermen. It’s a very good bargain.
M: Shark-fishing? I don’t think I fancy shark-fishing. Is there any chance of getting a bit of sailing in that part of Cornwall?
W: We don’t do any sailing holidays, sir. They are mostly organized by the sailing schools. But rowing, canoeing, yes. Are you fond of rowing, sir?
M: Well, I did a lot of rowing when I was at university, but I’m a bit out of practice these days. I don’t think I’ve handled a pair of oars since I went boating on the Thames ten years ago. No, I don’t think I’d like to spend my holiday rowing.
W: Try looking through some of these brochures, sir, and see if there’s anything that attracts you.
