| Cognitive linguistics is the focus and hotspot of current linguistic research.The research and application of cognitive linguistics have positive significance for analyzing lexical semantics and promoting teaching.As an important tool for language research and learning,thesaurus also has great development and application value.Based on the theory of cognitive linguistics,this paper takes the Modern Chinese Classified Dictionary(Su Xinchun 2013)as the source of research materials,and makes a quantitative analysis of the direction and mode laws of the mapping of lexical semantic classification in modern Chinese,and tries to introduce the rules into the teaching of vocabulary in Chinese as a foreign language.This paper exploring a research path that integrates cognitive category theory,lexical semantic classification,lexical semantic extension and vocabulary teaching.This paper is divided into five parts:The first chapter is the introduction,which mainly includes research purpose,research significance,literature review,research methods and research thought design.The second chapter introduces the theoretical basis of cognitive linguistics,seeks cognitive support for semantic extension and lexical semantic classification mapping,and discusses the cognitive process of lexical semantic extension from the aspects of categorization,protype category,decategorization,inequality of category and cross-category cognitive mechanism.The third chapter is the introduction of the construction of research materials and research database.The first part is the research materials.This paper selects the adjectives in the category of "Nature and state" in the " Modern Chinese Classified Dictionary" as the research materials.Based on the analysis of the semantic characteristics of the six lexical semantic classification of topography,perception,character,property,talent and condition,the difference level of conceptualization ability of the corresponding semantic categories of these six categories is determined according to the cognitive principle.The second part introduces the process and completion of database establishment from two aspects of calculation,automatic annotation and manual proofreading.The fourth chapter,based on the basis of Chapter 2 and Chapter 3,carries on the econometric statistics and cognitive analysis to the mutual mapping direction rule and mapping mode rule among the six lexical semantic classification respectively.The results of this paper are as follows:1.The mapping directions among the six lexical semantic classification are consistent with the difference level of conceptualization ability of corresponding semantic categories;2.The six lexical semantic classification mapping laws show that metaphor is more dominant than metonymy,affective similarity and explicit and intrinsic correlation.Chapter five,based on the review of the existing vocabulary teaching model,proposes the idea of introducing the lexical semantic classification mapping laws into vocabulary teaching,and introduces the concept of lexicon mapping law based vocabulary teaching model from five aspects:knowledge base construction,teaching content and implementation path examples,teaching objectives,applicable objects,applicable courses,and teaching suggestions.The last part is the conclusion of the paper,which summarizes the research views of this paper and reflects that it is not enough to put forward the prospect. |
