语言是一种特殊的社会现象,是社会约定俗成的。从社会习惯方面看,尽管“历史上的今天”是个推出不久的电视栏目名称,但类似说法早已存在。比如野猪林中,董超、薛霸操着水火棍,看着林冲,说道:“……你须精细着,明年今日是你周年。我等已限定日期,亦要早回话。” Language is a special kind of social phenomenon that is conventionally established in society. Judging from the social habits, although “today in history” is the name of a television program launched shortly, similar statements have long existed. For example, in the wild boar forest, Dong Chao and Xue Bajian held water fire sticks and looked at Lin Chong and said: “... you must be careful, and today is your anniversary next year. I have already set a date and I have to reply as soon as possible.”
