M: Hi, Anna! Welcome back! How was 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: Do you? Then take my advice, do the well-being(健康, 福利) 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(飞行视察反应) 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 made a lot of difference.
M: En. 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 free 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.
