M: Well, Cynthia, (19) our frost semester at university is almost over. I can’t wait for the holiday.
W: Me too, Edward! Why don’t we go somewhere far away and forget these 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 coast? It would be great to do some swimming and surfing there.
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. (20) 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. Visitors may do lots of things there and have a good time, 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 the tall buildings and the cars. There are enough of those around here. I vote for mountains.
M: All right, then, let’s do that. (21)Now we have to decide where we’re going to stay and how we’re going to get there.
