听力原文:M: My brother Steve has just done a course at the Queen's Park Summer 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 that he did not 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. ! expect it's made him more self-reliant.
M: That's what he says -- and now he wants me to go!
