听力原文：W: Why don't we go abroad for a change？ Where I'd like to go is France, Spain, or

M: Mm. I'm not all that keen really. I'd rather stay at home.

W: Oh, come on, Steve. Think of the sun !

M: Yes, but think of the cost! Going abroad is very expensive.

W: Oh, it isn't, Steve. Not these days.

M: Of course it is, Juliet. The best thing about having a holiday here in Britain is that it's cheaper. And an other thing, the traveling would be easier. No boats, planes or anything.

W: Even so, we've been to most of the interesting places in Britain already. What's the point in seeing them again？ Anyway, we can travel round Britain whenever we like. There's no point in wasting our summer holiday here.

M: Mm, I suppose you're right. Nevertheless, what I can't stand is all the bother with foreign currency, changing money and all that when we go abroad. I hate all that. And it's so confusing.

W: Oh, don't be silly, Steve.

M: And what's more, I can't speak any of the languages -- you know that. It's all right for you. You can speak foreign languages.

W: Exactly. You see, what I'd really like to do is practice my French and Spanish. It would help me a lot at work.

M: Mm, but that's no use to me.

W: But just think of the new places we'd see, the people we'd meet!

M: But look, if we stayed here, we wouldn't have to plan very much.

W: I'm sorry, Steve. No. I just don't fancy another cold English summer.
