听力原文：M: Hi, Anna! Welcome back! How's your trip to the States？
W: Very busy. I had a lot of meetings, so, of course, I didn't have much time to see New York.
M: What a pity! Actually, I have a trip there myself next week.
W: De you？ Then take my advice, do the well-being in the air program. It really works.
M: Oh, I read about that in a magazine. You say it works？
W: Yes, I did the program on the flight to the States, and when I arrived at New York, I didn't have any problem, no jet lag at all. On the way back, I didn't do it, and I felt terrible.
M: You're joking!
W: Not at all, it really meant a lot of difference.
M: Eh. So what did you do？
W: Well, I didn't drink, any alcohol or coffee, and I didn't eat any meat or rich food. I drink a lot of water, and fruit juice, and I ate the meals on the well-being menu. They're lighter. They have fish, vegetables, and noodles, for example, and I did some of the exercises in the program.
M: Exercises？ On a plane？
W: Yes. I didn't do many, of course, there isn't much space on a plane
M: How many passengers do the exercises？
W: Not many.
M: Then how much champagne did they drink？
W: A lot! It was more popular than mineral water.
M: So basically, it's a choice. Mineral water and exercises, or champagne and jet lag.
W: That's right! It's a difficult choice.
