This paper is to extract semantic features from modern Chinese action verbs and build a subset of semantic metalanguage.针对此课题，李葆嘉先生提出了语言学的元语言理论，其中析义元语言研究是其核心。
Finally, the author tried to grade the defining metalanguage and construct it in different semantic groups and hierarchies.最后尝试对释义元语言进行词汇等级划分和义类层级建构。
