Construction On The Semantic Network Of The Words With BAI In TCSL

“bai”is a polysemous morpheme with strong word formation ability,which can easily combine with other morphemes to produce new words and derive a large family with the same morpheme.In this paper,the semantic analysis of "bai" is carried out from the perspective of semantic category and cognition,based on the analysis of the corpus of CCL,the semantic development of "bai" is sorted out according to the time clues of semantic appearance,and the semantic network of "bai" and words with "bai" and the semantic network of TCSL are concluded.It is found that the semantic development is often from the representation of concrete things to abstract things,and the semantic category has the characteristics of changing from daily related to professional fields.Taking this as the core,this paper puts forward the principles of constructing the teaching semantic network,and applies the analogy of "bai" homology element group semantic network to it,considering that it has universal applicability.This paper is divided into four parts:The first part is the introduction.This paper first expounds the reason and significance of the topic selection,summarizes the previous studies including the relationship between morphemes and word meanings,,lexical semantic network and foreign language teaching,and the research on "bai" ontology,and explains the research methods and the source of corpus.There are few researches on the construction of teaching semantic network.The second part is the semantic analysis of "bai".First of all,the dynasty sequence of each semantic appearance of "bai" is investigated."bai" develops from basic color meaning to non-subjective semantic meaning,producing bright meaning,cognitive meaning and action meaning.When meaning of “noble-minded” “eminent”come out,it indicates that the meaning of “bai” begins to blend into a certain subjectivity.When meaning of “out of air” and the sememe with the presupposition negation develop,which is highly subjective,"bai" has already experienced semantic bleach.After semantic analysis and induction of the words with "bai",the semantic development network of "bai" and the semantic network composed of nearly 170 "bai" homophones are constructed by combining the theory of cognitive metaphor metonymy and semantic association.The third part firstly analyzes the sequence and frequency of words with "bai" in the comprehensive series of "Developing Chinese",and finds that the occurrence of words in the textbooks does not completely conform to the path of lexical semantic evolution.Secondly,the family of the "bai" is divided into two kinds of characterization of concrete things and characterization of abstract things,further refined classification on the basis of the development of semantic network,building a "bai" in conformity with the cognitive law of TCSL semantic network model,and build a “bai” semantic network in teaching "Developing Chinese".Compared to other previous semantic network,it is more in line with students’ cognitive regularity.Two basic principles of lexical construction are proposed: first,lexical meaning representation develops from concrete to abstract;Secondly,semantic categories are arranged from daily life to professional fields.The fourth part is the research on the analogy of the construction of "bai" semantic network in TCSL,and According to the research methods and principles summarized above,the semantic network of the color word "red" and the homologous element group of the parallel word "ba" is constructed for TCSL,which shows that the principles of the construction of semantic network in TCSL have some universal applicability.The fifth part is the summary of the whole paper.
