| Based on the study of predecessors’ time,this paper analyzes the components,construction meaning,syntactic function,discourse function and contextual conditions of "X" with the construction grammar theory,and analyzes the construction duration.Investigate and explore the motivations and mechanisms of the construction,and compare and analyze the ambiguity with similar constructions.The full text is divided into six parts.The first chapter is the introduction,which mainly explains the selection and significance of the selected topics,the current research status,the research object and scope,the theoretical basis of the research and the source of the corpus.The second chapter is the analysis of the construction of "X".The analysis of the "X" structure is carried out.Firstly,the characteristics of the components are analyzed,and then the corpus is used to refine the construction meaning.Finally,the syntactic distribution is described.The third chapter is the pragmatic analysis of "X".It studies the discourse function of "X",from the subjective review function,the defense function,the affirmative function,and the exaggerated highlight function.The anti-expectation theory is used to analyze the two from the perspective of anti-expectation,and the context conditions,communicative intentions and emotional colors of the construction are also examined.The fourth chapter is about the grammaticalization process of "X" and the related degree of semantic construction: the diachronic investigation of "X" is carried out,and the mechanism of "X" is explored to classify the emerging degree.The fifth chapter is the comparative analysis of "Y" and "X".It compares and analyzes the components and construction meanings of the two constructions,and compares the unique construction meanings of the two,analyzes the ambiguity phenomenon and analyzes it.method.The sixth chapter is the conclusion,summarizing the full text,summarizing the problems solved in this paper and the shortcomings. |
