听力原文：M: The guests are leaving for New York today on the ten o'clock flight. We need someone to get them to the airport on time.
W: Ordinarily, I'd be happy to, but my car is in the garage.
M: It doesn't matter. We'll take a taxt.
How are the guests going to New York？
听力原文：W: Well, Mr. Steve, we have had an interesting discussion about your work. Now, tell us something about your after work activities.
M: I guess not much different from everyone else. I'm fond of sports, and I am about 3 miles every day. I particularly enjoy cross-country running, where you have to run across fields, jump over streams and so on. While I'm running I think about all kinds of things, and at the end of a run I'm sometimes surprised to find that I've managed to solve a problem that was on my mind.
Next year I'm going to ay the London Marathon. It's a long, hard race—26 miles, or 42 kilometres and you have to be tough to finish, but I very much want to do it. I worry a bit about getting old, and I'd like to prove to myself that I'm still almost as well as I was twenty years ago. I'm interested in climbing as well as running. I'll never become an expert climber, but I know what I'm doing in the mountains. I successfully completed a course in snow and ice climbing when I was younger, and I've done a lot of easy climbs in the Alps during the last few years. My wife doesn't share my interest in mountains. She agreed to go climbing with me once, but she found that she felt sick as soon as she reached above 1000 metres, so we decided to follow different hobbies.
W: You certainly seem to enjoy various types of recreation. All right, Mr. Smith. Thanks for your interesting talk.
What are the man's hobbies？

M: Okay, how about dinner at the Grill？ You have to eat something, and it's right by the library. I'll go over there with you after dinner, and you can do your research while I study for my test.
W: Well, but...
M: Come on. You'll probably want to stay late, and you shouldn't walk home after dark. I'll stay until you're ready to go.
W: That would be nice, but...
M: Look, we really wouldn't be wasting any time. We'd just be doing everything we need to do, hut we'd be doing it together. I just want to spend time with you.
W: Me, too. Okay. I need to go home first, then I'll meet you at the Grill about six. Is that all right？
M: That's great. We'll get everything done. You'll see.
