Teaching Design Of Existential Construction Which Based On The Constructure-Chuck Approach

Existent sentence is a special sentence pattern.the study of existential sentences as a second language acquisition,we can easily find that the research on the teaching of existential sentences is still relatively weak.At the same time,we also analyze the general direction of Chinese learners' errors in learning existential sentences by sending out questionnaires,and find out the unique teaching order and functional expression of existential sentences.and it is difficult to master and use this sentence pattern flexibly in daily communication.On this basis,the grammatical point of existential sentences is designed and taught in the order from easy to difficult and from shallow to deep.Chapter one of this paper is a brief review of the literature on the ontology of existential sentences and the construction-chunk approach,which lays a theoretical foundation for the following chapters.Chapter two summarizes and the theoretical basis of constructive-chunk teaching method.It also analyses the applicability and feasibility of constructive-chunk teaching method in guiding existential sentences.The third chapter is to analyze the errors of the existing sentences by using the expected responses of students in class B,C,E and F of Harbin Normal University as the research object.Chapter IV is the main part of the whole paper.Combining with the previous chapters of research and investigation,a series of teaching designs can be applied to practical teaching are written.
