我们知道,语言是社会的交际工具,是一个历史范畴,有它的时代性。阅读古代作品,了解古代语言,无疑要注意作品的写作时代。比如现在叫做“碗”,古人叫做“案”,孟光“举案齐眉”的“案”就是“饭碗”。但刘禹锡《陋室铭》里“无丝竹之乱耳,无案牍之劳形”句的“案牍”却不能作为“碗”来解释,它只跟现代语中的“案卷”相当。 We know that language is a social communicative tool, a historical category, and has its own characteristics of the times. Reading ancient works and understanding ancient languages ​​undoubtedly pay attention to the writing age of the works. For example, now called “bowl”, the ancients called “case”, Meng Guang “case of case” is “rice bowl.” However, the “case” of Liu Yuxi’s “No Labrador’s Luan Er, Lao Xing Lao Xing” sentence in “Ugly Chamber Ming” can not be explained as a “bowl”, but it is only equivalent to the “case file” in modern Chinese.
