听力原文:M: You look happy. Did you sell lots of things at the store today? W: No. I bought something. It was a great deal. M: So what is it? W: A laptop computer. M: Really? That's great. It's really convenient. You can take it anywhere. W: That's what I thought. I can use the computer at home and at my store. M: What will you use it for at the store? W: To keep track of all the things in the store, and how much I sell them for. M: That's a good idea. But I didn't think you knew how to use a computer. W: I don't. M: Then why did you buy one? W: I've heard so much about computers. And I've heard you can find so many interesting things on-line. I was walking past the computer store downtown. I saw they had computers on sale. M: So you went into the store to ask a few questions. W: That's fight. And I met a nice, young salesman. He showed me lots of things a computer can do. I just had to buy one. M: So flow who's going to teach you to use it? W: You are. (23)
