A、Five. B、Four. C、Three. D、Two. D顾客针对新购随声听的投诉主要有两项：一是机身上的划痕。二是声音外漏，故选D。顾客说过，我真正不满意的是另外一件事。由此也可知投诉的问题一共是两项。

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.
