听力原文：W: Jones, have you chosen a physical education class yet for this semester？
M: No. Why？
W: You've got to take rock-climbing. We just had the first class and it looks like it's gonna be great.
M: You think I should take rock-climbing？ You've got to be kidding. 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 have 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. The ropes are made of elastic fabrics that stretch a little, the shoes have special grips on the bottom and the helmets are made of some kind of special plastic. You have to learn how to use all these before you do any real climbing.
M: Well, what's the appeal？ We'll spend the whole semester studying something we don't actually get to do.
W: We will take a climbing trip during spring break. But that's not the point. Climbing is not the only goal. In preparing to climb you learn patience, mental discipline and you gain fantastic physical strength, especially in your hands. For the first few weeks we're going to concentrate entirely on hand and upper body exercises.
M: All that in one sport？ Maybe you are right. Since it's not too late to join the class, maybe I will.

What is the purpose of this passage？
听力原文：W: Exercise, exercise, exercise! We hear so much about it these days that even the experts can't agree on which exercises are best. Now some doctors are strongly encouraging arm exercises.
M: Arm exercises？ I've never heard of that. Is that because our arms are too fat or flabby？
W: Actually, that's not the main reason. They say that arm exercises are an ideal way to become physically fit.
M: But don't arm exercises raise your blood pressure？ Seems I've read an article about that before. So, that's risky.
W: Not really. That they do, but the article I read mentioned several ways that can compensate for that.
M: Really？ How？
W: By adding leg exercise so the arms don't do all the work. Arm exercises alone aren't enough to increase metabolism before fatigue sets in. The more ot a body that involves in the exercise the better.
M: And in turn, I'm sure that there is a great chance of losing weight, right？
W: Sounds right to me.
M: So, what exercises do the experts recommend？
W: They mentioned quite a few. But some of the more popular ones are cycling with special bicycles that make you use both your arms and legs, and walking vigorously while wearing arm weights.
M: Sounds great. I must try that. You know, I like to walk a lot.
