On The Chinese Sentence Pattern Of “Cong X Shuo,Y(从X说,Y)” From The Perspective Of Self-limitation Of Evidentiality

“Cong X Shuo,Y(从 X 说,Y)” is a sentence pattern with special expressive function in Chinese.Based on the theory of deviation expectation and evidentiality,this paper systematically studies the types of components,the selection and restriction of components,and the pragmatic functions and influencing factors of the sentence pattern.First of all,this paper analyses the selection and limitation of “X ” in “Cong X Shuo(从 X 说)”,and studies the classification of “Cong X Shuo(从 X 说)”according to the type of “X”.In addition,the syntactic nature of the structure is judged as an atypical discourse marker.Secondly,it investigates the choice and restriction of “Cong X Shuo(从 X 说)” to the follow-up sentence “Y”,and based on this,it puts forward that there is a natural semantic antithesis structure in the followup sentence “Y”,and further explains the reason why the follow-up proposition “Y”is a non truth value and anti common sense proposition.According to the relationship between the internal semantic subjects of “Y”,it classifies “Y”,and concludes that there are mainly the following types: a belongs to B type;a does not belong to B type And B type;a non-B type(can also be divided into: A is not B type and a does not have B characteristic type);a and B opposite type and B non-A logic causal type.Based on the type of counter expectation of information,“Y” can be divided into two types: deviation from personal expectation and deviation from social sharing expectation.On this basis,this paper analyses the subjectivity and motivation of“ Cong X Shuo(从 X 说)”,discusses the determinants of its credibility and flexibility,focuses on the self limiting function of its motivation,and systematically describes its other pragmatic functions.Finally,it gives a detailed explanation of the interpersonal negotiation function and influencing factors of “ Cong X Shuo,Y(从X 说,Y)”.
