Now we are ready to start.

Interviewer: Excuse me, we are doing a survey. It’s a part of our university course and I would like to ask you a few questions if you don’t mind.
Respondent: No, I don’t mind. I used to do that sort of research myself when I was in high school.
Interviewer: You’re saying you are not studying at school any longer?
Respondent: No. I’m nineteen. I’ve already finished school. Now I’m a university student.
Interviewer: OK. You are nineteen. And I can register your occupation as a student, can’t I?
Respondent: Yes, you can. I study full-time and I’m going to be an economist.
Interviewer: My cousin wanted to be an economist too but then changed his mind and became a lawyer. He was not really good at mathematics, actually.
Respondent: Economics is not only about mathematics. To tell the truth, Maths has never been my favourite subject, not even at school.
Interviewer: What was your favourite one then?
Respondent: I’ve always liked Biology, but it has nothing to do with my future job, unfortunately.
Interviewer: Did you study Biology at school?
Respondent: Yes. And we had a wonderful teacher.
Interviewer: Right. OK. And what do you do in your free time?
Respondent: It depends. I like skiing and I go to the swimming pool from time to time, and I play in a band.
Interviewer: Play in a band? Drums or keyboard?
Respondent: No, the guitar. And I perform as a vocalist sometimes. Especially when we play Spanish songs.
Interviewer: Do you know Spanish?
Respondent: Yes. I speak it fluently. I learned it at school and now go on with my studies at university, too.
Interviewer: Would you like to learn any other foreign languages?
Respondent: I’ve been thinking about Chinese. It’s very useful for business in the modern world. Lots of people speak it. But…
Interviewer: It’s too difficult to learn, isn’t it?
Respondent: Yes. I don’t think I’ll manage to combine learning Chinese with my current studies and other commitments. Probably, some other time, in another life.
Interviewer: I do understand you. My days are very busy too and it’s difficult to find any extra time to do things you like. One more question if it’s OK with you...
Respondent: Yeah, no problem.
