【答案解析】[听力原文]
   M: All right, Miss Eppinger. I've confirmed your window seat and arranged for your baggage to be transferred to your connecting flight. Thank you for flying with us today. Is there anything else I can do for you?
   W: Actually, there is one thing. I want to buy a bottle of perfume at the duty-free shop as a gift. Do you know if I'll be able to carry that onto my connecting flight?
   M: Well, I know for certain that it won't be a problem on this leg of the flight, but your connecting airport could be a problem. It also depends on the security regulations of the airline.
   W: I really don't want to spend a lot of money on a gift only to have it taken away from me en route. Well, I guess I'll have to take my chances. Thanks anyway.
