参考答案：D

解析：[听力原文]1-4M: Do you really believe that clothes carry a kind of message and that what we put on is a reflection of what we feel W: Oh, yeah. Now people are beginning to take seriously the idea of a kind of psychology of clothing, to believe that there is not just individual taste but also a thinking that is trying to express something we may not even be aware of ourselves.M: But surely this has always been the case. We all dress up when we want to impress someone; we tend to put on something smart.W: But that’s a conscious act. What I am talking about is more of a subconscious thing. Take for example the student away from home at university: if he tends to wrap himself up more than others, this is because he is probably feeling homesick. Similarly, a general feeling of insecurity can sometimes take the form of overdressing in warmer clothes than necessary.M: Can you give any other examples W: Yes. I think people who are sociable tend to dress in an extroverted way, preferring brighter or more dazzling colors--yellows, bright reds, and so on.M: Do you think the care--or lack of it--over the way we wear has anything to tell us W: Yes, indeed. The length of a man’s trousers speaks volumes about his awareness of his own image. If his trousers are very short or having loosely, this probably means he’s absorbed by other things.
