| This paper studies the problems related to the grammar for teaching Chinese as a foreign language about the existential you-sentence and shi-sentence,discusses the fundamental differences between the two types of existential sentences and the semantic syntax performance,and tries to establish two kinds of sentence-style teaching grammar and puts forward some suggestions for the preparation of textbooks.The whole paper consists of five chapters as follows:Introduction,mainly introduces the research object,the significance of the study,the scope of research,the source of the material and the two kinds of existential sentence-style research status.The first chapter analyzes the rationality and teaching applicability of two types of existential sentence theory grammar,and analyzes the core differences of two types of sentence-semantic,semantic differences,and expounds the four semantic syntax manifestations of two types of sentence style caused by core semantics.The second chapter discusses the application of two types of sentence teaching grammar from the teaching point of view,and combines the analysis results of the first chapter,tries to establish two types of sentence-style teaching grammar,specifying the basic semantics of two types of sentence style,core semantics and six different contexts of use.In the third chapter,it examines the preparation of two kinds of existential sentences in the three sets of teaching materials: "New Practical Chinese Reader Workbook" "Boya Chinese" and "Development of Chinese",and puts forward three suggestions for the preparation of textbook: establishing a sense of contrast;Adopt a one-lesson,its phased writing;context,Context,Situational Arrangement.Concluding,summarizing the main research content and innovation points of this paper,and pointing out the shortcomings of the article.In general,the core difference between the two types of existential sentence is the difference of semantic delivery,and two different syntactic representations are produced under the core semantic drive.Therefore,in the process of teaching grammar establishment and textbook writing,we should embody the core differences of two types of sentence and different conditions of use and choice of context. |
