听力原文:M: Hi, Maggie! Haven't seen you for long! Where have you been these days?
W: I've been to Hong Kong for a few days.
M: Oh, have you been there on business?
W: No. Actually I've been there for a break with my boyfriend.
M: Really? I guess you must have had a wonderful time.
W: Yes, indeed. Hong Kong is such a lovely city, and it has got so much to see and do. We got up early and went to bed late; it was rather tiring.
M: What was the first thing on your list?
W: Ocean Park. It was so much fun! We saw a lot of sharks and dolphins; they were so cute when they were giving performances. Besides, the tropical fishes are just fantastic. I've even decided to keep some fish at my place.
M: Sounds interesting. Have you been to the Peak?
W: Yes, of course. We took the Peak Tram there, and we enjoyed a superb view of the whole Hong Kong, including the famous Bank of China Building.
M: Did you take any photos?
W: Yes. In fact, we took the video camera with us. Would you like to come over some day and watch the tapes?
M: That would be great!

听力原文:W: You will go down slow, Dan, I suppose?
M: Why, Tanya, it isn't a brave bouncing girl like you who asks that? Why, I always go down at full gallop. There's nothing like it for raising your spirits.
W: But perhaps you need not now.
M: Ah, there are two to be reckoned with. It is not me alone. Tib has to be considered, and she has a very queer temper.
W: Who?
M: Why, this mare. I fancy she looked round at me in a very grim way just then. Didn't you notice it?
W: Don't try to frighten me.
M: Well, I don't. If any living man can manage this horse I can: I won't say any living man can do it, but if such has the power, I am he.
W: Why do you have such a horse?
M: Ah, well may you ask it ! It was my fate, I suppose. Tib has killed one chap; and just after I bought her she nearly killed me. And then, I nearly killed her. But she's still very touchy; and one's life is hardly safe behind her sometimes. Don't touch my arm! We shall be thrown out if you do! Hold on round my waist!
W: Oh! Show more sense, please.
M: Let me put one little kiss on those holmberry lips, Tanya, or even on that warmed cheek, and I'll stop my honour, I will!
W: Will nothing else do?
M: Nothing, dear Tanya.
W: But I don't want anybody to kiss me! And I wouldn't have come if I had known!
