SECTION A CONVERSATIONSDirections: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.听力原文：M: My brother Peter has just done a course at the Green Park Camping School.W: That's great. What made him make such a decision?M: For one thing, some boys in his class dared him to go with them!W: You mean he wasn't really willing to go?M: He wanted to go but he was also a little frightened. Of course, now that he has done it, he's very pleased with himself and he's always talking about it.W: So he enjoyed it, didn't he?M: We cannot say so. 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: All sorts of open-air activities: camping, canoeing. One thing he had to do was to capsize a canoe and then right it again without getting out. The water was very cold but he hardly noticed it at that 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. He was frightened at first, apparently, but then he got used to it.W: The course did him a lot of good. I expect it's made him more self-reliant.M: That's what he says--now he wants me to go!What can we learn about Peter from the conversation?A．Peter cannot wait to attend the course.B．At first he was reluctant and timid.C．Mike enjoyed the open-air life very much.D．Peter did not get well along with his classmates.
