| As one of the most important parts of Chinese compound sentences,causal complex sentences are frequently used in both spoken and written language.For Vietnamese learners,Chinese and mother tongue causal complex sentences have many things in common,which can bring great help to Vietnamese students.The author adopts a comparative analysis method.In the process of comparing the causal complex sentences of the two languages,the author finds that the two are similar.The two are generally similar in definition,pragmatic function,and semantic function,but there are some small differences in syntactic function such as the position of the subject,related words,punctuation and so on.This article starts from the perspective of second language acquisition,taking Vietnamese learners as the object of investigation and adopts a variety of second language acquisition research methods such as comparative analysis,error analysis and a combination of quantitative and qualitative research methods.On the basis of comparing the results of the two languages,the author uses the "Beijing Language and Culture University Dynamic Composition Corpus" and the corpus of the questionnaire to analyze the errors that Vietnamese learners make in the process of learning and acquiring Chinese causal complex sentences and try to explore the errors and the reasons behind these errors.The author found that the main types of errors that Vietnamese students are prone to make in the process of using Chinese causal complex sentences are grammatical errors and semantic errors.These two types of errors can be divided into four minor types: "punctuation errors","related words incorrectly added","other component errors" and "semantic logic confusion errors".Through the author’s analysis results the main reasons for these errors are the negative transfer of the mother language and the lack of knowledge of the target language.Finally,based on the comparative analysis results of Chinese and Vietnamese causal complex sentences and the error analysis results of Vietnamese students’ acquisition of Chinese causal complex sentences,the author finds out the key points and difficulties of Chinese causal complex sentences for Vietnamese students,combined with the authors own Chinese learning experience the author puts forward some corresponding teaching suggestions.For the teachers,the author puts forward the comparative analysis method,the teaching principles from easy to difficult,intensive teaching and practice,and some suggestions in the practice part.For learners,the author encourages them to adjust their acquisition mentality,pay attention to active self-study,and input more Chinese.In the process of writing textbooks,the author proposes to strengthen pertinence,systematization,and strengthen after-school exercises.It is hoped that the research results of this article can provide valuable references for Chinese teachers and learners who are native Vietnamese. |
