听力原文：M: Which university do you think you'd like to attend？
W: Well, I've narrowed it down to two, so I'll choose one of them and keep the other as my hack up. How about you？
M: I'm in the same situation as you. A back up is a good idea because you might not get accepted by your first choice.
W: My first choice is London and my back up is Cardiff. How about yon？
M: I went for Edinburgh as my first choice and I'm keeping Belfast as my back up. What made you decide on London？
W: Well, it's ranked highly in the subject I want to study, accounting, and it means I can live at home with my parents, which will save on money.
M: I can understand those reasons, but I think one of the benefits of going to university is that you can live away from family.
W: Which is why you're going to the other end of the country! I see what you mean, but money's tight and I'd rather stay somewhere that's familiar to me.
M: So why have you chosen Cardiff as your back up？ There are plenty of other universities in London.
W: My grandmother lives there. She's said that she'd appreciate having me around. So why did you choose Edinburgh and Belfast, aside from getting far away from your family？
M: Well, there's the fact that they're both rated highly in the field I want to study—economics. Aside from that, I liked the way they presented themselves on their websites. There was plenty of information and it seems that the life there is pretty good.
W: What in particular caught your eye？
M: Well, Edinburgh has a well-organised climbing club. It's also famous for its arts and music festivals. There's a lot going on considering it's not a very large city.
W: Will it be expensive to live them？
M: It will be more expensive than average. Rents have gone up a lot in recent years. However, it will be cheaper than London.
W: Unless you live with your parents!
M: I think they'll be happy to see me go to another city and live on my own.
W: At least your poor mother won't have to wash your stinking socks!
