一位挑水夫,有两个水桶,分别吊在扁担的两头,其中一个桶子有裂缝,另一个则完好无缺。在每次长途的挑运之后,完好无缺的桶子,总是能将满满一桶水从溪边送到主人家中,但是裂缝的桶子到达主人家时,却剩下半桶水。两年来,挑水夫就这样每天挑一桶半的水到主人家。 One water picker has two buckets that are hung on two ends of a pole. One of the buckets has cracks, and the other is intact. After each long-distance picking, the intact bucket can always send a full bucket of water from the stream to the owner’s home, but when the cracked bucket reaches the owner’s home, half a bucket of water remains. In the past two years, the water picker took a bucket and a half of water every day to his home.
