"A" Of The Usage Of Foreign Language Teaching And Its

"Le" is an important grammatical words, and it is also one of the difficulties in Chinese learning. Although there are many academic study of "Le", but it is not full enough. In the field of teaching Chinese as a foreign language,it is also a big problem. Based on the previous research,I made a systematic study of the usage of "Le",and summarized the types of errors made by foreign students by using the method of error analysis for the acquisition of "Le",and put forward the relevant suggestions for teaching."Le" is divided into "Le1" and "Le2"."Le1" appears after the verb, if the verb has an object,"Le1" before the object, Expressing that action is completed or implemented, on grammar it is called dynamic auxiliary "Le";"Le2" usually appears at the end of a sentence, Express changes or that the emergence of new situation, often called the modal particle "Le" This paper summed up Seven usages of "Le1", five kinds of usage of "Le2", and analysis of "Le1" and "Le2" when they appear at the same time.Based on the analysis of errors made by the students in HSK dynamic composition corpus. I summed up the error types of "Le".They are the missing of "Le", the adding of "Le", the misplacing of "Le" and the mix using of "Le1" and "Le2". Analyzing the reasons of the errors, there are five main conditions:the negative transfer of native language, target language rules overgeneralization, teaching material factor, the complexity itself, lack of teaching guide. Of course, due to the limited level of the author, the reason of error are not be comprehensive, therefore it needs to be added.Finally, combined with the "new Chinese" and "Chinese advanced tutorial", and researching the arrangement of grammar items, talking about specific scheduling problems of "Le", we can see the positions of "Le1"and "Le2" in the textbook.I gave some suggestions on the writing of textbook and teaching Chinese as a foreign language.
