听力原文：M: So, you're an architect.
W: Yes.
M: Do you work for a public or a private organization, or you're self-employed, that is working on you own？
W: I'm working for a private designing construction company.
M: How did you start your career？
W: I started it with the government.
M: Oh, did you？ What made you decide to work for the government？
W: Well, it was a matter of chances, really. I saw an advertisement for a vacant position in the newspaper and I thought "why don't you try it". In fact, I have no preferences where I work, public or private.
M: And do you still have this idea, or...
W: More or less, yes. Although I'm now working with a private firm, I worked for the government for about three years. It was all right. Of course, there is the bureaucracy that one has to put up with but that's no that had. If you don't mind bureaucratic wheels turning slowly and things not being as efficient.
M: Mm, ha, and what made you leave the public sector？
W:Money mainly. You see, I got married, and my husband doesn't work, and we wanted to start a family right away. So we thought it might be better if I moved to the private sector. This is why it's hard for me to be self-employed, because self-employed work has a disadvantage that there may be time or a period of time when you are unemployed.
