W: John, have you chosen a physical education class yet for this semester?
M: No. Why?
W: ( 13) You’ve got to take rock-climbing.（ 女士在劝服男士和她一起上攀岩课。）
M: You think I should take rock-climbing? You’ve got to be kidding.
W: No. Listen, we just had the first class and it looks like it is going to be great.
M: Somehow, I doubt it. Besides, how can they teach rock-climbing when it’s completely flat around here?
W: That’s not important. You can’t just start climbing without any training. You had to get in shape, learn how to use the ropes, the belts, the buckles, there’s a lot of preparation first.
M: You don’t think it’s just a little bit dangerous?
W: Not if you know how to use the safety equipment, which is, by the way, pretty hi-tech.
M: That seems to be interesting. Tell me about that.
W: Ok. First, the ropes are made of elastic fabrics that stretch a little, and the shoes have special plastic. You have to learn how to use all these before you do any real climbing.
M: (14) Well, what’s the appeal? We’ll spend the whole semester studying something we don’t actually get to do.（ 可见男士对攀岩课不以为然，觉得花一个学期学习不会真的去做的事没有什么吸引力。）
W: We will take a climbing trip during spring break. But that’s not the point. Climbing is not the only goal.
M: It’s not? So what is supposed to be the purpose?
W: (15) In preparing to climb you learn patience, mental discipline and you gain fantastic physical strength, especially in your hands.（ 女士讲到学习攀岩的目的是学会忍耐，精神上的训练，还有锻炼体力，即增加上体力量。）For the first few weeks we’re going to concentrate entirely on hand and upper body exercise.
M: All that in one sport? Maybe you are right. Since it’s not too late to join the class, maybe I will.
