听力原文：M: Hello, Nancy. I know you are one of the women taxi drivers in the city now. What does it take to become a good taxi driver, do you think? W: Eh, besides driving well, the most important thing a taxi driver needs to know is the streets, and I knew the city well because I had lived in it for a long time. M: Now, what about annual leaves? Do you have them? W: Oh, yes. When I first started, I had only ten days. Now, I have three weeks every year, with pay. M: Are there any unpleasant aspects in your job? W: The only serious difficulty in this work is that it's sometimes dangerous to drive at night. But you have a choice, and I always choose to work days rather than nights. M: Then what is the best part of your job? W: I soon found that what ! liked best about this job was being outdoors, seeing how the city changes from season to season. And there are places I've seen that I probably never would have seen in another job, and I love all kinds of weather. M: Being a taxi driver, you have to meet all kinds of people. How do you feel about that? W: I enjoy meeting many different people. I might not have met some if not for this job and I've learned a lot about how people behave in these years. M: Now, my last question. Have you ever thought of changing your job? W: Not yet. I might, in a few years' time. But not at this moment, because I really enjoy my work, and I do get a lot of satisfaction out of it. So, why should I? 22．What is regarded as an unpleasant part of Nancy's job? 23.What does Nancy like best about her job? 24.What kinds of people does Nancy meet? 25.What do we learn about Nancy from the conversation?
