《左传》选文《郑伯克段于鄢》,现在已成了高校《古代汉语》教材“文选部分”的保留篇目;对“郑伯”之“伯”的解释也可以说相当一致,即皆认为“伯”是爵位名称。如王力主编《古代汉语》(修订本)第一册这样注释:郑伯,指郑庄公。春秋时有五等爵:公、侯、伯、子、男。郑属伯爵。 The text “Zuo Zhuan” is an article entitled “Zheng Boke is in Yu Yan,” and now it has become a reserved part of the ancient Chinese textbook “Wenxuanzuo”. The explanation of “Zhu” of “Zheng Bo” is also acceptable That is quite consistent, that is, that “” is the title of the title. Such as Wang Li editor of “Ancient Chinese” (Revised) Volume I Note: Zheng Bo, referring to Zheng Zhuang. Spring and Autumn five Grandmaster: male, Hou, Bo, son, male. Zheng is the Earl.
