【正确答案】 B

【答案解析】[解析] 男士说Maybe we should buy a bigger one．所以答案为B。 [听力原文] 11-13 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 color 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.
