“从/否”类副词是经历自先秦到后期近代汉语的漫长历史才形成的,其间发生过两次显著的变化:一是短语词化,由上古就已出现的时间短语“从X以(已)来”在一定的句法环境里经缩略而形成副词“从来”;二是伴随着省缩改变分界、重组词化,在“从来+否定副词+谓词”句式范围内,“从来”省缩为“从”,并且跟否定副词组合成具有“时间.否定”意义的“从/否”类副词。 The adverbs of “yes / no” are formed through the long history of the modern Chinese from the pre-Qin period to the later period. There are two significant changes during the period: one is the phrase-writing, the time phrase “ Has been ”to“ form an adverb ”never“ in a certain syntactic environment through abbreviation; secondly, with the province shrinking to change the boundary and reorganize the lexicon, within the sentence pattern of ”always + negative adverb + predicate“, ”never“ The province is reduced to ”slave“ and combined with negative adverbs into ”yes / no“ adverbs with the meaning of ”time negation".
