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! What is the possible relationship between the two speakers?
