【答案解析】[听力原文]
   W: I think there's an area we can all improve on—scheduling our time better and working smarter. Now, if you're like me, you may find you're doing too much planning and researching, and don't have enough time to finish your projects. For me, I feel that if I did a better job of scheduling my time, I would get things done more efficiently and not have to work overtime so much. To accomplish this, I've created an outline of everything I should think about before taking on a project. This will allow me to plan out my time more effectively, set deadlines for myself, and delegate some of the tasks to others in the team. The outline will also make me aware of any potential problems that I wouldn't usually think about. I urge you to try this method and see how much it improves your efficiency in the next six months. We'll all meet again in the coming months to find out our progress and report on whether your objectives were met on time.
