W: What are you reading, Bill?
M: It’s this week’s New Scientist, why?
W: I was just wondering. It looks interesting. It is for real scientists or can ordinary people like me understand it?
M: Oh, it is for anyone really. It usually has articles and stories about character affairs and about science as well as papers about a new development and research. I am reading about a new telephone that allows you to see the person you are 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 it has color and the image is moving.
W: That’s interesting.

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 hundred pounds, but the one the story is about costs several thousand pounds.
W: Er. Why does anybody want one, do you think?
M: Business organizations that need to frequently contact overseas organizations would want it. It is like a face-to-face conversation. So maybe a lot of overseas travel can be avoided.
W: Yes, I suppose so.
