| In recent years, with the continuous improvement of China’s international status, the status of Chinese in the world language system is also increasing."Chinese fever" continues to heat up, Confucius college and Chinese education in foreign countries have sprung up. Students come to China to learn Chinese is gradually increasing. Under this kind of environment, the cause of teaching Chinese as a foreign language is developing vigorously. Chinese is a kind of language lack of morphological changes which is the main means of word order and grammatical function words. If we say that vocabulary teaching is one of the difficulties in teaching Chinese as a foreign language, then there is no difficulty in practical teaching of function words is the difficulty. The preposition as a function, students naturally difficult to accept the part in the daily teaching. It is very necessary to carry out systematic research on preposition in order to promote the development of the teaching of Chinese as a foreign language. Domestic experts and scholars have made a thorough study on Chinese preposition ontology, obtained a number of valuable research results.On the origin of prepositions, definition, classification, Xing Fuyi, Hu Yushu, Liu Yuehua and other experts have in-depth study, although the academic world for preposition classification problems still exist great controversy but they still provides a lot of reference value on the preposition research and learning. On the basis of research on Ontology of prepositions, prepositions for foreign language academic research also carried out like a raging fire. However, throughout the study of foreign language, the study of prepositions, mainly focused on the analysis of the deviation of the preposition in the country and the comparative analysis of the preposition, yet the overall lack of research on prepositions. Moreover, although in the study, most scholars think in Chinese learning, resulting in students of preposition errors of a big reason is the compilation of teaching materials defects, but very few scholars for teaching prepositions systematic investigation, thereby textbook make recommendations to improve the properties, and make recommendations accordingly teaching. According to the analysis of the preposition in the teaching material, it has a very positive significance both in theory and in practice. In the ontological of the study preposition on preposition classification controversial article in which the largest number of a selected object-prepositions as research subjects.This paper is divided into four modules, the first module is the introduction part, it mainly introduces the source of the topic of this paper and the research significance and research methods. And for preposition of ontology research and Foreign Teaching Chinese were reviewed research, combined with the public-word, select the object class preposition as research subjects, and comprehensive scholarly.research,selected,include"dui,xiang,ba,bei,rangjiao,duiyu,guanyu,zhiyu,gei, wei,ti,gen,yu, bi, you", the 17 preposition object classes as research subjects. In order to facilitate a more systematic and comprehensive study object class preposition, these 17 objects prepositions agent are introduced into the introduction of Shoushi and the introduction of three categories, respectively, and things research according to the difference of the dielectric function of the lead object class. The second module is the object class for the three categories proposed introduction of prepositions, were studied in detail. Among the many foreign language teaching materials, this paper selects the classic textbook of teaching Chinese as a foreign language "Chinese course" as a research model, in exclusion under the premise of multi category words, for times and frequency of the material object preposition were artificial statistics, and the material object preposition and the vocabulary outline and HSK exam papers were compared and analyzed, with examples, starting from the point of view of grade and recurrence rate, in-depth study of the distribution of materials in the object preposition is reasonable. The third module is a further object class textbook grammar prepositions project with "Syntax Outline" were analyzed. In "Syntax Outline" as the frame of reference for teaching grammar prepositions object class project detailed memory statistics measured by the rank and reproduction ratio textbook grammar prepositions object class project analysis, study textbooks on grammar prepositions object class project arrangement is reasonable. The fourth part is mainly based on the survey results of the second and third part, combining "word outline", HSK exam "Grammar Syllabus" on the "Chinese Course" made part of the preparation of improvements, including the optimization of object classes preposition level in the distribution of textbooks; textbooks reasonable increase or decrease the number of occurrences of the preposition object class; adjust textbook selection and distribution of object classes grammar prepositions related projects and the like. In addition to textbooks and papers for the measurement statistics and outline the process of discovery of "Words Outline" defects on the "Glossary Outline" proposed improvements. Actual teaching in addition to materials of the recommendations, the paper also for teachers object class preposition also made some recommendations, including the adoption of classified teaching; binding test questions rational design exercises; focus on teaching reproduce, sum up learning errors; focus summarized, teachers, etc. to enhance the initiative. Teachers hope to combine the above recommendations, artificially to a certain extent make up for defective materials so students can learn better and faster to use and flexible object class preposition. |
