听力原文：M: Hello madam, can I see your passports and tickets? W: Certainly, here you are. M: OK, that's fine. Where would you like to sit? Any preference? W: Yes, I think maybe quite near to the toilet, for the kids. You know how they get when they are traveling. Mine get so excited they need to pee all the way there! M: Yes, the joys of taking the kids on a plane. That's no problem. You are all seated together, in the middle row. Seat numbers K20-24, near to the toilets. W: Perfect, thanks. M: Hear are your boarding passes. How many bags do you want to check in? These 3 large ones? W: Yes. You know women we can never travel light, most of that is my clothes! M: You would be surprised how much luggage some people take on holiday, this is nothing compared to that! So, that's everything, if you would like to make your way through to departures. Have a good flight and enjoy your holiday. W: Thank you. We will. (23)
