| The grammatical meaning of modern Chinese conjunctions is more complex,and they cannot be used alone or serve as sentence components.To study the error situation of Bangladeshi students in China learning the conjunctions "he","er" and "bing" can improve the Chinese learning level of Bangladeshi learners and accumulate experience in international Chinese education and teaching.This research takes 53 international students from Bangladesh who come to China as the survey object.Error analysis,comparative analysis,and interlanguage theory were used to conduct the research.To investigate and analyze the errors of Bangladeshi Chinese learners at the intermediate and advanced levels,questionnaire surveys,comparative analysis and interview methods were used as research methods.In this research,the error analysis of the Chinese conjunctions "he","er" and "bing" by Bangladeshi Chinese learners and corresponding suggestions are given.The article is divided into six parts:The first and second chapters mainly introduce the basic information of the research such as the origin,meaning,objective,and method of the research,as well as conjunctions related to research in China and foreign countries.The third chapter is the comparison of similar conjunctions between Bengali and Chinese.The Bengali conjunction "(?)" is only used to connect words,it can’t connect phrases,sentences and clauses.The Chinese conjunction "bing" can connect words,especially two verbs or verb phrases.The Chinese conjunction "er" can connect words,phrases,sentences and clauses and the Bengali conjunction "(?)" can connect phrases,sentences and clauses,but it can’t connect words.The fourth and fifth chapters are the survey design and result analysis of the research respectively.The types of errors generated are addition,omission,misgeneration,wrong order and errors of connecting components.Among these types of errors,substitution has the highest error rate.The reasons for the errors are the negative transfer of mother tongue,generalization of target language knowledge rules,improper learning strategies of students,language individual factors,textbook compilation and teaching design,etc.The sixth chapter is about the teaching and learning strategies of Bengali learners regarding the conjunctions "he","er" and "bing".Learning strategies include comparative study,clarifying rules,strengthening exercises,etc.When writing textbooks,it is necessary to increase knowledge of conjunctions,avoid simple English annotations,and increase targeted exercises.Teachers should carefully design teaching methods,supplement the missing textbooks,and timely detect students’ errors and problems that should be corrected.The last part is the conclusion,which mainly summarizes the research and explains its limitations of the research. |
