When George was thirty-five, he bought a small plane and learned to fly it. He soon became very good and made his plane do all kinds of tricks.

George had a friend. His name was Mark. One day George offered to take Mark up in his plane. Mark thought, "I've traveled in a big plane several times, but I've never been in a small one, so I'll go."

They went up, and George flew around for half an hour and did all kinds of tricks in the air.

When they came down again, Mark was very glad to be back safely, and he said to his friend in a shaking voice, "Well, George, thank you very much for those two trips in your plane."

George was very surprised and said, "two trips?"

"Yes, my first and my last," answered Mark.

乔治今年35岁了，他买了一架小型飞机，开始学习驾驶。他很快就掌握了飞机的驾驶技巧，并可以做出各种各样的特技飞行。

乔治有位朋友叫马克。一天，乔治主动邀请马克来乘坐他的飞机。马克心里琢磨：“我曾乘坐过好几次大客机，还从来没乘坐过小飞机，我应该去体验一下。”

飞机升空后半个小时左右，乔治在空中展示了各种各样的飞行特技。

最后，当他们再次安全地回到地面后，马克显得十分激动。他用颤抖的声音说道：“乔治，非常感谢你让我乘小飞机做的两次飞行。”

乔治听了，非常吃惊地问：“两次飞行？”

“是的，我的第一次和最后一次。”马克答道。
