    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 smoke was everywhere in the plane. 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 and mend the machine." said the pilot, taking one of the parachutes. There was nothing he

could do, so he jumped out.

      The first person stood up, "I'm a doctor," he said. "I help people live longer and I save lives." He also

took a parachute and jumped out.

The next person said, "I must have a parachute. I am a very clever person. I have to go to an important

sport match. I know I'll 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. By this time the plane was going down fast. The businessman said, "Young man, I am old but you're still young. You take the last parachute. "The young mountain climber smiled, "Don't worry," he said. "We can both jump to safety because there

are still two parachutes. Just now the clever man jumped out with my backpack."
