An Investigation And Teaching Research On The Use Of Polysemous Words In HSK Vocabulary Syllabus For International Students Based On DST Theory

In the teaching of Chinese as a foreign language,vocabulary teaching,as an important part of teaching,always runs through the whole process of Chinese learning for foreign students,while polysemous words,as an important part of modern Chinese vocabulary,have the characteristics of large quantity and complex meaning system.The emergence and development of polysemous words follow the economic principle of language development,and the semantic system of polysemous words has the characteristics of dynamic complexity because of the development of language duration and the use of synchronicity itself.Students also have some unbalanced and dynamic characteristics in the specific use of polysemous words in the HSK Vocabulary outline.DST theory,as the frontier research direction of the current two-language world,thinks that two-language learning is a complex and nonlinear process.Then,from the point of view of holism and system theory,analyzes the multi-system of HSK lexical outline,It is the focus of this paper to investigate the use of polysemous words in the outline and put forward reasonable suggestions for the teaching of polysemous words.On the basis of the DST theory,this paper investigates and analyzes the polysemous system in the HSK Vocabulary Outline and the specific use of polysemous words in the syllabus by foreign students.It is concluded that the polysemous system in the outline itself has the characteristics of development and complexity,and that the students also have the characteristics of repetition and complexity in the process of specific use.Therefore,it is proved that the acquisition of polysemous words by foreign students is a complex and nonlinear process of development.The main factors affecting the acquisition are the mechanism of language evolution and the individual differences of learners,Finally,the author puts forward some scientific suggestions on the teaching of polysemous words from different stages and the specific teaching design of polysemous words.As teachers of Chinese as a foreign language,they should learn to design the teaching of polysemous words from the whole perspective,and respect the differences of students' cognitive level so as to carry out effective teaching.
