A doctor, a lawyer(律师),a little boy and an old man were out for a Sunday afternoon flight on a small plane. Suddenly, the plane had engine(发动机) trouble. It began to go down. At last, the pilot took a parachute(降落伞) and shouted to the four people that they had better jump, and then he himself jumped out.Unluckily, there were only three parachutes left.
The doctor took one and said," I'm a doctor. I save lives, so I must live."Then he jumped out. The lawyer then said,"I'm a lawyer, and lawyers are smart people in the world. I must live."He also took a parachute and jumped out.
The old man looked at the little boy and said,"My boy, I live a long and full life. You are still young.Take the last parachute and live in peace."The little boy handed the parachute back to the old man and said,"Don't worry, grandpa. The smart man in the world just jumped out with my schoolbag."
