M: Well, uhm, it'd be great to get away, but I've never done it before. W: None of the others have either except for me. I went once last fall. But there'll be an instructor in each canoe the first day. M: I don't know. W: Oh, come on. This is our last chance to take a break before finals. The scenery is beautiful, and if it gets too hot we can dive in whenever we feel like it. The river's really calm this time of the year, no rapids to deal with. M: That's a relief. What would I have to bring？ W: Let's see. Tom's bringing food for the Friday night cookout for everyone. And the people who run the trip have tents set up and they supply food and drinks for all day Saturday. On the way back Sunday morning we'll stop somewhere for breakfast. So, you have to bring a bathing suit and a sleeping bag. M: Well, I do love camping and sleeping out. Where is this place？ W: Well, it's about an hour and a half to the place where we meet the trip leaders. We leave our car there and they drive us and then canoes upriver to the place where we start canoeing. M: And who's driving us to the meeting place？ W: Well, I was hoping we could take your car. Mine's in the shop again. M: Oh, I see. It's not me you want, it's my car. W: Don't be silly. So what would you say？ M: Oh, why not! W: Great!

They're happy to help out because it's towards an education；as long as we're not just wasting it all in drinking it all away. I am in the 3rd year.1 went to the end of my overdraft a couple of times and I'm lucky to have middle class parents who can help me out really. M：But mostly your finances have been poor! W：(24)That's because of the summer. If I just 1ived as a normal student and then worked during the summer it wouldn't be so bad—but I go on big holidays and things. This year I went to the Philippines and then came back overland from Singapore, which is a wicked experience, but eats into your finances obviously. What about you？ M：My parents came to the arrangement that first of all they paid the fees for me；secondly they paid my hall fees； and thirdly they gave me an allowance. W：That's quite practical. But can you manage？ M：Yeah, I did excellently. I decided first of all I was going to get a first, which I did, and secondly 1 was not going to have any debts.(25)I put the money in a high interest account, so I came out with no debts at all.
