　　“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'm a very clever person．I have to take part in an important sports match．I know I'll win the game because I'll be the cleverest person there．”He picked up a pack(包)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'm 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 person jumped out with my backpack．”
