【甲】秦王欲以五百里之地易安陵，安陵君弗敢易！秦王不悦。安陵君因使唐雎使于秦。……秦王曰：“天子之怒，伏尸百万，流血千里。”唐雎曰：“大王尝闻布衣之怒乎？夫专诸之刺王僚也，彗星袭月；聂政之刺韩傀也，白虹贯日；要离之刺庆忌也，仓鹰击于殿上。此三者皆布衣之士也，怀怒未发，休祲降于天，与臣而将四矣，若士必怒，伏尸二人，流血五步，今日是也。”挺剑而起。秦王色挠，长跪而谢之。

    【乙】公输盘为楚造云梯之械，成，将以攻宋。子墨子闻之，起于鲁，行十日十夜而至于郢，见公输盘。……王曰：“善哉。虽然，公输盘为我为云梯，必取宋。”子墨子解带为城，以牒为械。公输盘九设攻城之机变，子墨子九距之。公输盘之攻械尽，子墨子之守圉有余。公输盘诎。子墨子曰：“吾知子之所以距我，吾不言。”楚王问其故。子墨子曰：“公输子之意不过欲杀臣。杀臣，宋莫能守，乃可攻也。然臣之弟子禽滑厘等三百人，已持臣守圉之器，在宋城上而待楚寇矣。虽杀臣，不能绝也。”楚王曰：“吾请无攻宋矣。”

    This happened about one thousand and seven hundred years ago．One day somebody sent Cao Cao, the king of Wei an elephant．Cao Cao wanted to know its weight(重量)．“Who can think of a way to weigh it?”he asked．But nobody knew what to do because there was nothing big enough to weigh it．

    Then Cao Chong, one of the king's young sons, came up and said, “Father, I've got an idea．Let me have a big boat and a lot of heavy stones, and l'll be able to find out the weight of the elephant．''

    Cao Cao was surprised, but he told his men to do as the boy asked．When the boat was ready, the boy told a man to lead the elephant down into it．The elephant was very heavy, and the water came up very high along the boat's side．Cao Chong made a mark along the water line．

    After that the man drove the elephant onto the bank．Cao Chong then told the men to put heavy stones into the boat until the water again came up to the line．

    Cao Chong then told the men to take the stones off the boat and weigh them one by one．He wrote down the weight of each stone and then added up all the weights．In this way he got the weight of the elephant．
