【正确答案】
B
【答案解析】[听力原文] W: Yes, can I help you? M: Yes, you see I bought this personal stereo at your shop three days ago, and I'm afraid that it hasn't really matched up to what I was told about it. W: I see. What exactly is the matter? M: Well, first of all, there is this large scratch across the front of it. W: But you should have noticed that when you bought it. M: But it was in the box and all sealed up. W: Well, I'm sorry. But it really is your responsibility to check the goods when you buy them. How are we to know that it wasn't you who made the scratch? M: That was ridiculous! But anyway, it's not the most important thing. I really am not happy about this other thing. W: And what is that? M: Look! It says here that the noise from it should be undetectable by other people. W: Yes, that's right. M: But people can hear it and it's really embarrassing on the bus and the underground. W: Well, I'm sorry. But it must be the way you are wearing the headphones. M: Look! I know how to put earphones in my ears. Thank you very much! But what I want to know is what you are going to do about it at all! W: Well, I suppose we could exchange it for another model if you really aren't happy with it. M: No, I certainly am not! W: Well, if I could just have your receipt? M: Oh, yes. Well, There is a slight problem about the receipt... Why didn't the customer notice the scratch on the product? 对话中顾客反映他新买的随身听有一个大刮痕，店员问他怎么在购买时没发现，顾客回答说他没打开包装，也就是说，顾客没有检查产品。故选B项。虽然录音中提到随身听密封在盒子里，但这不是最直接的原因，因此C错误。
【正确答案】
C
【答案解析】[听力原文] About the scratch on the product, what did the shop assistant think? 由录音材料中的you should have noticed that和it really is your responsibility to check the goods可知，店员认为顾客在买东西时就应该看清楚商品的状况，因此C正确。本题易误选A，因为原文中有How are we to know that it wasn't you who made the scratch?(我们怎么知道这划痕不是你造成的呢?)但这句话并非就认定是顾客造成了划痕，故不可选A。
