【正确答案】 B

【答案解析】[听力原文]11-13 Mrs. Field: You must have this suit cleaned. It's very dirty. Look, there are some stains on the front and dirty marks around the pockets of your trousers. This suit is so dirty that it will stand up itself. Mr. Field: All right, I'll take it to the cleaner's. But you see, I 'm always so busy. It takes me so much time. And I have so much work to do. Mrs. Field: I can't understand why you always buy dark suits. Why don't you buy a few light - colored suits for a change? Light - colored suits are much nicer. They will make you look younger, too. Mr. Field: Perhaps they will. But they easily get dirty in London. London's air isn't exactly clean and light - colored suits will show the dirt. I'll have to take them to be cleaned once a month. Mrs. Field: That's better than once a year. Dark suits get dirty just as light - colored ones but they don't show it. At least, you can buy different color suits for a change. Mr. Field: That is why I wear them to look attractive when I go to the theater or to a party. Everyone wants to look attractive before others. Mrs. Field: That's right! You at last got the message.
