听力原文:Woman: I'm sorry I'm late again. I ran out of gas. Can you believe it? Man: You should take the bus. Then you wouldn't have to worry about gas or flat tires or anything like that. Or, even better, get up earlier and walk. That's what I do. I walk to work every morning. Woman: Well, I tried taking the bus yesterday, and I got here even later than I do when I drive because it has to stop at every bus stop. It takes forever. Man: See? Walking's the fastest way. It only takes me 45 minutes to get to work. And I always arrive feeling relaxed and energized. Woman: Well, it would take me a lot longer than it takes you. I'd have to train before I could walk that fast, and anyhow, I live a lot farther away than you do. Why was the woman late today?
