【正确答案】 A

【答案解析】[听力原文]18-21 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 here in your store. It's a bright metal shelf, almost a yard long and two feet high. It can be attached to a cabinet or refrigerator. I'm a biologist and I want to use it for my slides and samples. M: You're in the right department. But I'm sorry to tell you that we don't have it in stock now. It seems that quite a few people are in need of it. W: Oh, that's too bad. Are you going to get more? When is it possible for me to come again to buy it? M: They axe on order now. They will arrive in about several days. I will inform you as soon as it is available. But what I should tell you is that the price has gone up a little. W: Just my luck. Anyhow I don't mind the price because it is what I'm looking for. M: Right! When you really need something and find it useful, price is second in consideration. W: Would you tell me something about the price change? M: Originally they were $12. 50. But the new ones will almost three dollars more. Stop in next week. We should have them by then. 由第一轮对话女士话语中的your store、第二轮对话男士话语中的You're in the right department即可知对话发生在大商店里，女士是在买东西，选[A] 。

【正确答案】 C

【答案解析】第一轮对话中女士明确说明了自己要买的东西：It's a bright metal shelf，因此答案为[C] 。

【正确答案】 B

【答案解析】在最后一轮对话中，男士交代了架子的原价和新价：Originally they were $12.50．But the new ones will almost three dollars more。将两个数字相加即得新的价钱是15.50美元。

【正确答案】 D

【答案解析】答案信息同样在最后一轮对话中男士的最后两句：Stop in next week．We should have them by then。也就是说下周将有货，所以他才让女士下周来。
