听力原文:M: Well, Cynthia, our first semester at university is almost over. I can't wait for the holidays. W: Me, too, Edward! Why don't we go somewhere far away and forget about lectures and essays and all that hard work. M: Sounds good to me. Now, how long will we have before we have to be back here on campus for the next semester? W: We've got about six weeks, I think. M: How about if we go to the coast7 It would be great to do some swimming and surfing. W: The coast would be good, but let's look at our other options. There are the mountains. They're nice and cool at this time of year. And we can do some bush-walking. There's also the desert, which I really enjoyed last year. M: What about going to Sydney? I've never been there and they say it's a great city to visit. Lots of things to do there, I've heard. W: I agree Sydney would be good but there are too many tourists there at this time of year. And I'd 'rather get away from buildings and cars. There are enough of those around here. I vote for mountains. M: All right, then, let's do that. Now we have to decide where we're going to stay and how we're going to get there. Where did the woman go for holiday last year?
A.
A mountain resort.
B.
A seaside resort.
C.
A desert.
D.
The outback of Australia.
