dialogue: M: And when did you begin this sort of work? W: Let me see. Um...Yes, four years ago. M: And you enjoy it? W: Oh yes, very much. It is very tiring with long hours on the jobs, sometimes...uh...as much as 12 hours. But it's exciting to meet people from all over the world. It really is. M: What exactly do you do? W: Well, I take tourists to the famous places in the city, tell them the history of the places, and tell them why they're famous. M: What special qualifications are necessary for guides? W: Well, they have to enjoy meeting new people. And they must take special courses in the history of the city and things like that. M: And do they have to know a foreign language? W: That's a must. My company will hire only people who speak at least two foreign languages. M: And you? How many foreign languages do you speak? W: I speak three: Spanish, French and Italian. M: Three foreign languages? Then I can see why your work is so easy for you.
