听力原文：I: Hello, Nancy. I know you are one of the few women taxi drivers in the city now

N: I took pride in driving well even when I was young, for I had to wait until I had a car to learn to drive. When 1 finally learned, it was something I really enjoyed and still enjoy.

I: I see. And how long have you been a taxi driver？

N: Er... altogether 12 years.

I: Mm... It has been quite some time already, hasn't it？

N: Yeah.

I: Then, what did you find the hardest about becoming a taxi driver？

N: It was scary. I did not yet know how to judge distance, and when a truck came nearer, it seemed like its wheels would just come right over me. Anyway, soon I learned it ail and stopped worrying.

I: In your opinion, what does it take to become a good taxi driver？

N: Er... besides driving well, the most important thing a taxi driver needs to know is the streets, and I knew the city well because I'd lived there for a long time. And, of course, you have to keep updating your knowledge of the streets because the city changes.

I: Now, what about annual vacation？ Do you have them？

N: Oh, yes. When I first started, I had only 10 days. And now 1 have 3 weeks every year with pay.

I: Just out of curiosity, when you go on vacation to another place, do you drive there as well？

N: In most cases, not. I prefer to be driven by others if we go by car. I've had too much driving in my life. So when on holiday, I just want to relax.

I: OK. Our interview is coming to the end. Thank you for your time.

N: Pleasure.
