听力原文：W: Can I help you, sir? M: Um, yes. I bought this radio cassette player here a couple of weeks ago. Here's the receipt. W: Ah ha. That's fine. What seems to be the problem? M: Well, it's been nothing but trouble since I bought it. W: OK. Just let me take a note of this. Er, radio cassette player. M: The first thing is one of the speakers doesn't work properly. The sound is completely distorted with the radio or a tape. W: Which one is it? M: The right-hand one. Another problem is the left cassette player. It chews up tapes. It's completely ruined two of my favorite cassettes. W: Oh, dear. The speaker and the cassette player. M: One of the cassettes was brand new. Oh, and the rewind switch doesn't work. Actually it never did. W: OK. So there is the right-hand speaker ... the cassette player and ... urn, the rewind switch. Is that it'? M: No, I'm afraid not. The aerial doesn't work properly. It's stuck. W: Hmm, 1 see what you mean. The handle is broken too. M: Yes, I'd forgotten about that. It's not very good, is it? W: Er, no. But it's under guarantee and we can repair it. Just give me your name and phone number. We'll give you a ring when it's ready. Where are the two people, most probably?
