听力原文:W: Simon, how does it feel to be retired? M: Well, not so bad. W: How have you been spending your time? M: I've been spending more time with my family. I've also travelled a bit, you know, off season when everywhere is less crowded and hotels cost less. W: Great. M: You know I haven't stopped work completely, W: Yes, could you tell us more about this? M: I'm on a scheme that's called phased retirement. I had a six-month break from work, after that I could apply for project work with the company I used to work for. W: How does the scheme work? M: Well, it's a trial at the moment. Instead of hiring temporary staff, the company advertises posts on its website that retired employees like myself can access. W: What sort of works advertised? M: Well, all sorts of things, really. Administrative work and more specialized work, the sort of thing 1 can do. Some of the projects can last five or six months, and others can just be a couple of days. I can decide more or less when to work, so I can manage my own time. W: I can see it's good for you. What does your company get out of this? M: Well, I still have all my old contacts at work, so I know who to contact to get something done. The company gets flexibility, too. Once the job's over, that's it. I'm not on their books any more.
