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 actaully 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 current affairs, about science, as well as papers about new developments in research. I'm reading about a new telephone that allows you to see the person you're speaking to, as well as hear him.

W: Oh, I've 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's what they called, were made in Japan. But they can only show a still black and white iamge. So this video phone is much better than that. Mind you, I'm not sure I'd 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 ones cost several hunderd pounds, but the one the story is about costs several thousand pounds.

W: Mm... 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.
