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 I 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? Questions 22 to 25 are based on the conversation you have just heard. 22.
