听力原文：M: Erm...you left an informal report with Sergeant Dawkins. There's just a couple of things I'd like to check on. Could you describe the girl to me in a bit more detail, please? W: Yes. She was darkish. I should think she was between twenty-five and thirty roundabout. And she had shortish hair. I think she had a fringe, but untidy. M: Did you notice the clothing at all? W: Er...she had a white collar...open-necked shirt I think...or blouse and what looked like a velvet jacket but I can't remember the colonr...I think it was a green or a brown but it was some dark colour. M: OK. Well, let's go to the man now that you just saw...if you could just describe him to me because there wasn't much on the report that you left with the sergeant. W: Yes...well...I noticed he was wearing a funny kind of woolen jacket. M: A bulky sort of jacket, was it? Thick knit or...? W: Well...yes...nut really very bulky. It looked as ff it was knitted and it had a sort of woolen collar and I think he was wearing an open-necked shirt too. He was younger than her. I should think he was in his early twenties. M: And she looked older? W: She looked a bit older, to me. Erin...he had his hair brushed back. M: Yes. Anything about the shirt that you noticed...was it just a plain white shirt or was it any other sort? W: I think it was striped but I can't be perfectly sure, but I do re member his hair was sort of wavy and brushed back and shortish. M: OK. Well, that's fine. Thanks very much. If you leave your phone number with the desk sergeant, maybe we'll contact you in the near future. (20)
