A Study On The Error And Teaching Of "Ba" Sentence Based On Information Structure Theory

“Ba” sentence is a special sentence pattern in Chinese,and it is also a key point in the teaching of Chinese grammar as a foreign language.But “Ba” sentence is difficult to teach and learn,so the problems it faces are quite complex.This paper intends to study “Ba” sentence from a new perspective,we intend to put “express the result change”,“express the identity” and “express the displacement” as the research object,on the basis of language information structure theory to explore the information structure characteristics of “Ba” sentence,and from the perspective of information structure to analyze the errors made by students corpus,find rules,and then give the relevant teaching design.About the “express the result change”,its information structure features are as follows: the disposer should be the topic;the disposal of the results should be the information focus,preposition “Ba” is used to introduce the disposal object into the sentence,so as to enhance the "strong influence" of the sentence and highlight the disposal result.We then analyzed the errors made by students corpus from language information structure,respectively from the topic,secondary topic,the information focus,the transition of the four sections,inductive each part often appear the types of errors and consider the cause of errors and the related teaching or acquisition.About the “express the identity”,its information structure features are as follows:the knower should be the topic,the cognitive mode and the cognitive result should be the information focus,and the preposition "Ba" should be used to enhance the“subjective identification” of the sentence.On this basis,from the perspective of language information structure,we analyze the types of errors in the four parts of "Ba" sentences,and consider the causes of these errors,as well as the relevant teaching and acquisition.About the “express the displacement”,its information structure features are as follows: the disposer should be the topic,the disposal method and the final position should be the information focus,and the word "Ba" is used to introduce the disposal object between the topic and the information focus,so as to strengthen the "disposability" of the whole sentence.We started from four parts,topic,secondary topic,information focus and transition,consider the causes of these errors,as well as the relevant teaching and acquisition.Based on the above analysis,we believe that foreign students may fail to understand the uniqueness of “Ba” sentence,which leads to various errors.In this regard,we try to design a teaching scheme of “Ba” sentence based on the information structure theory,which shows our thinking about the application of language information structure to the teaching of “Ba” sentence.
