听力原文:M: After you complete your presentation points, I can go over the details of the new hardware features using the prototype blender. W: I took the hardware home last night so that I could do more graphics for the presentation. It's still there. M: All right. It's only 10 a.m. We still have time to bring it back to the office. How long will it take you to go home? W: Actually, I don't think I have time for that. I have a meeting right after I finish rehearsing this with you. If I give you my house keys, can you bring it back to the office? What are the speakers preparing for?
