| This passage selects six constructions of modern Chinese,which are "nongbuhao" "shuobuding" "shuobuzhun" "baobuzhun" "baobuding" "zhibuding" to express the meaning of indefinable.The passage looks these six constructions as the research object and uses the cognitive grammar theory and other related theories,combines with the data,discusses the similarities and differences in the three aspects of syntax,semantics and pragmatics of these six constructions,in order to reveal the reasons that six constructions can coexist in the language system.At the same time,the synchronic research and diachronic studies are combined to examine the grammaticalization process of the six constructions,and the grammaticalization mechanism and motivations of these constructs are analyzed in detail so as to study the structure comprehensively and deeply.This paper is divided into four chapters:The first chapter introduces the research status and content,significance and objective,research ideas and methods.The previous constructions researches discussed these constructions separately,or at the same time to discuss several grammatical processes,but the studies are not deep enough,this paper is based on the previous constructions researches then studying in multi angle,and comprehensively.The second chapter is divided into three aspects from the perspective of synchronicity:First,in the syntactic aspects,the grammatical meaning of these constructs is analyzed and the interactive relationship between the verb and the construct is analyzed too,and the syntactic distribution of these constructs is analyzed in detail and the strength of the speculative ability of these constructs is analyzed.In the syntactic function,these constructs mainly act as adverbial,but also act as the parenthesis;Finally,the syntactic limitations of these constructs are analyzed,and the limitations of the subject of the sentence and the limitations of the other adverbs are analyzed.The second part introduces the semantic features,semantic background,semantic tendency,semantic orientation and summarizes the semantic features of these six constructs,Constructing the semantic patterns of these constructs,through the corpus analysis,it pointed out that the common pattern is "A +(X)B",the article gives a reasonable explanation from the cognitive point of view.In the semantic orientation,the article mainly analyzes the positive and negative tendencies,pointing out that only "nongbuhao" has a negative tendency and explores the reason that it is related to the emotional color that expresses unquestion in its semantics.Thirdly,the article studies the six constructions from the following three aspects:context and communicative modality,the choice of sentence type in terms of pragmatics.Then,the paper analyzes the influence of several contexts on these constructs.Communicative modality features include speculation,implicit functions,and cohesive functions.Finally,the article analyzes how these constructs choose statements,questions,exclamatory sentences.The article also studies the reasons why these constructs can not appear in the imperative sentence.In the third chapter,the article examines the grammaticalization of these six constructs from the diachronic perspective,the article holds that there are similar grammatical phenomena in the process of grammaticalization.The article points out that other constructs such as "gaobuhao " and " naobuhao " " baobuqi " also exist the phenomena of analogy syntax.The fourth chapter summarizes the full text and expounds the main points of this paper and points out the inadequacies of the paper and the direction of future efforts. |
