汉语词类问题，讨论了很长时间；本文认为不按汉语特点，不问前提，不作对比，盲目地因袭模仿的“语法体系”，只会离汉语语料、语感越来越远，其实用价值也不会大。回顾词类研究的历史，正反映了以上观点。又欲仿陈寅恪先生《四声三问》之风，故采用问答式。 This paper argues that the “grammatical system” which blindly imitates imitations without the precondition of Chinese language and without any prior knowledge of the Chinese language will only be farther and farther away from the Chinese corpus and language sense and its practical value Not big.
