【答案解析】[听力原文]
   M: Well, Shirley, now that we've seen the three apartments. Which one do you like best?
   W: I don't know, Brad. I know one thing. I didn't like the one on the 68^th street.
   M: Neither did I. Let's cross that one off. That leaves the 7^ndstreet one and the 80^th street one.
   W: The one on the 80^th street has a better view and a very cheerful kitchen.
   M: Yes, and I like the carpet in the hall. It was clean, but there was no good place to put a desk.
   W: That's true. You should always just put it in the corner of the living room. But then you wouldn't have any privacy and the bedroom was too small.
   M: Right! And I do need to be able to leave my work out on the desk without having it looked into by noisy visitors.
   W: Oh, Brad, we don't have that kind of visitors, but I do agree the desk shouldn't be in the living room. It is a constant reminder of unfinished work. What about the 72^nd street apartment? It has a dining area. We could eat in the kitchen and put the desk in the dining area. It's more private there.
   M: Yes, that sounds OK. Only what I didn't like about that place was the west window. It gets quite hot in the late afternoon with the sun beating down on the window.
   W: Didn't you notice the air-conditioner?
   M: No. Was there one?
   W: Yes, and we can improve on the curtains too.
   M: That place did have the best parking facilities of the three?
   W: Yes, I think that apartment is best for our needs. There's good parking and there's a semi-private area for your desk that takes care of the daily activities. We'll just let the other chips fall where they may.
   M: OK. Let's take that one.
   How many apartments have they seen?
