听力原文：M: Good morning. Can I help you？

W: Hello. My name's Jill Bush. I'm planning to go to a conference in Sydney for three weeks.

M: I see. Do you want the excursion fare or the full return fare？ W. Now, can I get a stopover on an excursion fare？

M: Yes, you are allowed only one stopover on the excursion fare.

W: Oh, I see, only one.

M: Yes. But of course, if you pay the full return fare then you can have unlimited stopovers. There's Singapore, Kuwait, Athens, you've really got quite a lot of choices you know.

W: Oh, It sounds good. You see, I've got a two-week holiday after the conference. How much is the full fare？

M: The full fare？ Well, that's really quite a lot. It's ￡ 1,204.

W: Yes. Well, it's once in a lifetime, you know. The thing is actually that I'm absolutely afraid of flying. I've never done it before.

M: Oh dear. Um…

W: And I'm hoping that I can persuade my two friends to go along with me.

M: Yes, that would be a good idea.

W: By the way, one of them is in Cairo at the moment. Would it be possible for me to stopover there on my way to Sydney？

M: Yes, of course. There are lots of flights to Cairo and, then plenty more onwards from Cairo to Sydney. And then you can stay for as long as you like.

W: Oh, that's great! Thanks very much.

B．Visiting a friend in Cairo.
