听力原文：M: Come in, Sharon and take a seat. W: Thanks. M: So, where do we start? Should we begin with a look at last year and then go on from there? W: Fine. M: So, how do you feel you've done in your first full year with the company? W: Overall, I think I've done quite well. I feel quite confident now about what I do. M: And are you happy with your duties? W: Well, the job is exactly as it was advertised in the paper, so there have been no surprises.
