听力原文：Woman: I need a screwdriver. Do you mind if I borrow yours？
Man: Go right ahead. It's in my toolbox in the closet, but please don't forget to return it soon. I don't want to lose it, and I'll need to use it later, anyhow.
Woman: Don't worry. You'll have it back before lunch. I just need it for a few minutes to tighten up some screws on this bookshelf.
Man: Just put it on my desk when you're done. I'll use it to fix that squeaky chair before. I go home tonight.
