【答案解析】[听力原文]7-10 W: What are you reading, Bill? M: It's this week's New Scientist, why? W: I was just wondering. It looks interesting. But I've never actually read it myself. It's for real scientists— or can ordinary people like me understand it? M: Oh, it's for anyone really. It usually has articles and stories about character affairs and about science as well as papers about new development and research. I am reading about new telephone that allows you to see the person you are speaking to as well as hear him. W: Oh, I heard about it. Is it on the market yet? Can I buy one? M: No, not this one. But the company has made other models to try out on business. This one is special because its color and the image is moving. W: Oh, that's interesting. M: You see the first video phones that what they called were made in Japan. But they can only show a still, black and white image. So this video phone is much better than that. Mind you and I'm not sure I want one, would you? W: Well, no. I don't think I would. I bet it costs a lot of money. Does it say how much it costs? M: Yes, the early black and white one costs several hundred pounds, but the one the story is about costs several thousand pounds. W: En. Why does anybody want one, do you think? M: Business organizations that need to frequently contact overseas organizations would want it. It's like a face-to-face conversation. So maybe a lot of overseas travel can be avoided. W: Yes, I suppose so.
