听力原文：W: I am exhausted. My new exercise class is so hard.

M: Your new exercise class？

W: Yeah. My new advanced exercise class.

M: Why advanced？

W: My instructor thought that the beginner's class was too easy for me. So I took an advanced exercise class.

M: Ha-ha, too easy for you？

W: Don't laugh. In the beginner's class, they give you a chance to rest between exercises.

M: So？

W: The advanced class is nonstop.

M: A piece of cake. You see, I lift weights every morning for sixty minutes without stopping. No problem.

W: Listen, Richard, doing aerobics for an hour is a lot different than lifting, weights.

M: Yeah. Quite a bit different; I think aerobics is easy. I could work out in your class with no problem.

W: You are not going to be able to move after weight lifting and the aerobics class.

M: Are you kidding me？ It's going to be a piece of cake. You want to bet？ I bet I can go one hour in your class tomorrow morning and not feel a thing.

W: The bet is--I win, and you cook dinner for the entire family, or you win, and 1 cook dinner for the entire family.

M: It's a bet. When's the next class？

W: Tomorrow morning at ten o'clock. Try it？

M: No problem. Tomorrow morning after lifting weights, I'll try aerobics. It's a snap. Tomorrow morning at ten o'clock.

W: OK. Call my instructor, Jack Davis, right before you go there. His number is 555-8844. Remember the advanced class starts at ten o'clock. It only takes eight minutes by bicycle to the aerobics class.
