| In modern Chinese,there are ten kinds of “Biaohao” in punctuation marks,each of which has different functions.From the perspective of international Chinese teaching,the current academic research on “Biaohao” is slightly insufficient,and “Biaohao” teaching is not very ideal.Therefore,this paper selects “Biaohao” as the research object,and uses the corpus collected in the HSK dynamic composition corpus and the global interlanguage corpus as the research basis to study the acquisition errors of “Biaohao” in the written expression of second language learners.This paper is divided into four parts.Firstly,the current situation of the use of “Biaohao”by second language learners is investigated,and the frequency,function and writing of“Biaohao” are summarized and analyzed.Through the analysis of the frequency of use,“Biaohao” is divided into two types : common and uncommon.Further analysis results show that when second language learners use “Biaohao”,the frequency of use of different “Biaohao”is different,and the frequency of use of different forms of the same “Biaohao” is also significantly different.For the function of “Biaohao”,second language learners do not involve all its functions when using it.In addition,compared with the use of infrequent “Biaohao”,the difference in the number of different functions in common “Biaohao” is more obvious.In terms of writing,although there are many writing forms when second language learners write“Biaohao”,they are still mainly in the form of standardized writing.Secondly,on the basis of the analysis of the current situation,the errors of the second language learners in using “Biaohao” are further analyzed.In terms of function,the common errors mainly include the misuse,omission and redundancy;among them,the frequency of misuse is the highest,accounting for 47.3 %.In “Biaohao” writing,there are two kinds of errors in the form and format;among them,form errors are more common,which are divided into simple form errors and confusion with mother tongue writing.Thirdly,it analyzes the causes of errors when second language learners use “Biaohao”.From a subjective point of view,teachers do not pay enough attention to students ’ “Biaohao”errors,lack of unified teaching standards,as well as negative transfer of mother tongue and students ’ neglect of “Biaohao” learning,these are the subjective reasons for errors;from an objective point of view,the imperfection of the explanation and practice part of the textbook,as well as the influence of the non-standard use demonstration of Chinese native speakers and computer input form,are the objective reasons for the errors of second language learners.Eventually,specific suggestions are put forward for the problems found in the research.In terms of teachers ’ teaching,teachers should pay attention to the comprehensiveness of“Biaohao” explanation,compare the labels of different languages,and pay more attention to the correction of students ’ label errors.In terms of textbook compilation,the textbook should improve the demonstration content and increase exercises related to “Biaohao”;in terms of student learning,second language learners should correct their attitudes and enhance their awareness of “Biaohao” learning. |
