There was a pilot and four people in a small plane. Suddenly there was something wrong with the machine while it was flying in the air. The plane began to fall down. The pilot told the people there were only four parachutes (降落伞). They all became worried and started to make excuses.

“I must go,” said the pilot, taking one of the parachutes and jumped out. The first person stood up, “I’m a doctor,” he said. “I help people live longer and I save lives.” He took a parachute and jumped out.

The next person said, “I must have a parachute. I am a very clever person. I have to attend an important match. I know I will win the game because I’ll be the cleverest person there.” He picked up a pack and jumped out.

Two men were left---an old businessman and a young mountain climber. At this time the plane was going down fast. The businessman said, “ Young man, I am old but you are still young. You take the last parachute.” The young mountain climber smiled. “Don’t worry,” He said. “ We can both jump out because there are still two parachutes. Just now the clever man jumped out with my backpack.”
