In modern Chinese,the auxiliary word is the most Chinese typological type, and the hardestto master for students. With deepening of research of the teaching Chinese as a foreignlanguage, the word extroversion study has attracted the attention of the academia, and hasmade a lot of achievements. But the Chinese textbook research, word acquisition, erroranalysis, especially the auxiliary teaching methods and other aspects of the auxiliary word arestill obviously insufficient,.Basing on the study of the auxiliary word from the modern Chinese and teaching Chineseas a foreign language, we’ve made a more comprehensive study of the auxiliary word.According to the inspect of the auxiliary word in Chinese learners’ dictionaries, the coveragerate in the" Outline" of particles is less than80%, still not comprehensive enough; there isalso problems with the number and the balance of the examples given. Based on students"HSK dynamic composition corpus" auxiliary error investigation and analysis, we find outstudents have very big difference in acquisitioning of the auxiliary word, such as “using thewrong word"" missing the word" and" adding the unnecessary word" and others. So theimbalance of error type exists; students of different Chinese levels in the acquisition of theauxiliary word also have a lot of differences, so the error imbalance of students’ grades alsopresent.On the foundation of systematic investigation and analysis of the auxiliary word which isdealt with in compilation of textbooks of teaching Chinese as a foreign language, ininterpretation of foreign learners’ dictionary, in auxiliary error from foreign students, fromstudent needs of learning the auxiliary, we puts forward some suggestions of the auxiliaryword teaching in teaching Chinese as a foreign language, including the identification of keywords and complex auxiliary key grammar project, particle schedule design of auxiliary,auxiliary teaching mode and so on. The conclusion of this paper has certain theoretical andpractical significance on teaching Chinese as a foreign language. |
