This paper takes the complement " jin(?)" as the research object and studies the related problems of its grammaticalization.The content covers five parts:The introduction mainly introduces the research object,expounds the significance of the topic selection and the predecessors' research on " jin(?)",and explains the applied theories,methods and corpus sources.The second chapter first studies the syntactic and semantic attributes of the complement " jin(?)" from the synchronic level,which can serve as the result complement,the state complement and the degree complement.When it acts as a different complement,the syntactic structure of " V/A+ jin(?)" has similarities and differences." jin(?)" has different meanings when it is used as different complements,and its semantic orientation is also different.The third chapter also studies and analyzes the choice of the predicate from the synchronic perspective.When the complement " jin(?)" is used as a different complement,the choice of the predicate is also different.This chapter mainly studies what characteristics the predicate has in syllables,semantics and situation.The fourth chapter studies the periods when various complements " jin(?)" appear,as well as the syntactic structure and semantic features in each period from a diachronic perspective.On this basis,the synchronic and diachronic study of the complement " jin(?)" is integrated to find out the course of the grammaticalization of the complement " jin(?)" and try to explain the motivation and mechanism of its grammaticalization.The fifth chapter is the conclusion,which summarizes the main contents of the full text,points out the innovation points,analyzes the shortcomings and puts forward the direction that needs to be done in the future.
