Separable words are a special kind of modern Chinese vocabulary,and they have the distinctive feature of "can be separated and combined".From the perspective of teaching practice of Chinese as a foreign language,separable words are a difficulty for foreign students to acquire Chinese,and it is also a focus of teaching.Although the previous research in the academic circle has been more systematic and in-depth,there are still deficiencies in the integration of teaching materials and the degree of refinement of the research.In view of this,the thesis is based on the double-syllable predicate-object separable words in the vocabulary list of "Development of Chinese: Elementary Synthesis"(Ⅰ,Ⅱ)and the two-syllable predicate-object in the elementary level vocabulary part of "Chinese Proficiency Level Standards and Grammar Level Syllabus" Separate words,select 32 overlapping words among them as the research object,draw lessons from error analysis theory,constructivist learning theory and prefabricated language block theory,comprehensively use statistical analysis method,comparative analysis method,questionnaire survey method and interview survey method,To study the grammatical errors of double-syllable predicate-object separable words for Korean students at elementary level,and to explore the causes of grammatical errors.On this basis,from the aspects of emphasizing language comparison,strengthening classroom teaching,and improving teaching materials,it proposes countermeasures for the teaching of predicate-object separable words for Korean students at the elementary level,aiming to more effectively improve the teaching of double-syllable predicate-object separable words and learned effects.In addition,the thesis also discusses the compilation of an online dictionary of double-syllable predicate-object separable words for Korean students at elementary level based on "Development of Chinese: Elementary Synthesis"(Ⅰ,Ⅱ). |
