【答案解析】[听力原文]
   W: Hi, Emma's speaking. Who's this?
   M: Hi, Emma. I'm Paul from Emingl's delivery service. Here is a package for you. Are you at home to collect it?
   W. Oh, sorry, Paul. I'm out at the moment. Can you put it in my mailbox?
   M: I'm afraid I can't do that. Sorry. The package is too big and it needs a signature to confirm you have received it, so I would need to deliver it at a time when you are in.
   W: Okay, well, I'm out all day today, but I should be in tomorrow morning before I go out for lunch. And then I'll be at home again later in the afternoon. Will either of those times be convenient for you?
   M: They're not unfortunately. I'm sorry. I won't be in the area tomorrow as I have some other deliveries to make on the other side of town. I could come the day after if that suits you.
   W: Okay. Yes, that should be fine. I have a friend coming round in the afternoon, but I'll be at home. So the day after tomorrow will be great. Do I need to pay for the package?
   M: No, you don't. It says here that you paid for it when you ordered it online.
   W: Oh, yes, I did. I got mixed up.
   M. So you just need to sign the form to say you've received it.
   W: Okay, great. See you the day after tomorrow then.
   M. Yes, see you then.
