听力原文：M: My brother Mike has just done a course at the Green Park Camping School. W: Really! What made him decide to do that? M: Well, for one thing, some boys in his class decided to do it and they dared him to go with them! W: You mean he didn't really want to go? M: I think he wanted to go but I think he was also a little frightened. Of course, now that he's done it, he's very pleased with himself and he's always talking about it. W: So he enjoyed it, didn't he? M: Not exactly. I think he's enjoying the feeling of having done it more than he enjoyed actually doing it! W: What sort of things did he do? M: Oh, all sorts of open-air activities: hiking, camping, canoeing. One thing he had to do was to capsize a canoe and then right it again without getting out. He said the water was very cold but that he hardly noticed it at the time. W: Why not? M: He was too busy righting the canoe! W: That doesn't sound very comfortable at this time of the year. M: That's what I said when he told me. On another occasion he had to spend a day and a night by himself in the open country. W: Was he frightened? M: He was at first, apparently, but then he got used to it. W: It seems to me that the course did him a lot of good. I expect it's made him more self-reliant. M: That's what he says—and now he wants me to go! (20)
