Mary, I hope you are packed and ready to leave.
W: Yes, I’m packed, but not quite ready. I can’t find my passport.
M: Your passport? That’s the one thing you mustn’t leave behind.
W: I know. I haven’t lost it. I’ve packed it, but I can’t remember which bag it’s in.
M: Well, you have to find it at the airport. Come on, the taxi is waiting.
W: Did you say taxi? I thought we were going in your car.
M: Yes, well, I have planned to, but I’ll explain later. You’ve got to be there in an hour.
请问最后一句: in an hour是一个小时后,还是一个小时内(到达)?谢谢!
