听力原文:M: Hi, would you like some help? W: Well, I'm looking for something I saw at a friend's house a few days ago. He said he bought it here. It's a light metal shelf almost a yard long with a magnetic brace that I can attach to a cabinet or a refrigerator. I'm a biologist, and I want to use it for my slides and samples. M: You're in the right department, but we don't have them in stock now. W: Oh, that's too bad. Are you going to be getting more? M: They're on order, but I should warn you that the price has gone up. W: Just my luck. M: They were $ 12.50(twelve-fifty), but the new ones will be about three dollars more. Come in next week. We should have them by then. W: OK. I'll be back. Thanks. (26)
