一天晚上,在漆黑偏僻的公路上,一个年轻人的汽车抛了锚:汽车轮胎爆炸了! 年轻人下来翻遍了工具箱,也没有找到千斤顶。怎么办?这条路半天都不会有车子经过,他远远望见一座亮灯的房子,决定去那个人家借千斤顶。在路上,年轻人不停地在想: “要是没有人来开门怎么办?”“要是没有千斤顶怎么办?”“要是那家伙有千斤顶,却不肯借给我,那该怎么办?” One night, a young man’s car threw an anchor on a dark, off-highway: a car tire exploded! The young man rummaged through the toolbox and did not find a jack. What to do? This road will not have a car after half a day, he saw a lamp from afar, decided to go to that person by jack. On the way, the young people kept thinking: “What if no one opens the door?” “What if there is no jack?” “What if the guy has a jack but refuses to lend me?”
