【正确答案】 A

【答案解析】[听力原文]
M: Hi, Mary. We haven"t seen each other since we graduated. Where have you been?
W: I have been to Australia. Do you still live there?
M: Oh, no. We have just moved into the new house.
W: Really? Congratulations!
M: Thank you, and we want to buy a new television.
W: What kind of television do you want to buy?
M: A colour TV, of course, but I"m not sure about the size. Maybe we should buy a bigger one. If we buy a smaller one, we might have to change it in a few years"time for a bigger one. That would be a waste of money. What is your opinion?
W: In my opinion, I don"t think it"s necessary to buy a very big one.
M: Any reason?
W: Yes. As I know, your sitting room isn"t big enough. If you put in a very big television, that will be bad for your eyes, and a smaller size TV can also pick up good programs.
M: Mmm, that"s quite true. I"ll think about it.
W: You"d better make a quick decision because the price may go up soon.
