Research On "Le₁" And"Le₂" Acquisition Of International Students

Based on the international students’ acquisition of "Lei" and "Le2", we mainly divide the thesis into three parts, thus the introduction, main body and conclusion. Chapter1is the introducing part which we introduce the purpose and meaning of the study, the research status as well as the research method and train of thought. Then the main part includes the second chapter to the fifth chapter.The ontology research of "Lei" and "Le2" is analyzed and described in Chapter2. On the basis of investigation and analysis of modern Chinese corpus, we consider that "Lei" is used after verbs. It mainly means the completion of the action. However, according to the meaning of the verb itself and the verb phrases as well as the sentence patterns, grammatical meaning of "Lei" can also be divided into "the action ends","mission accomplished" and "status". Meanwhile, this paper believes that the use of Xiao Zhiye, Shen Jiaxuan (2009) where proposed "act, know, speak" three fields to describe the grammatical meaning for "Le2" is reasonable.In Chapter3, we investigated and analyzed the usage of "Lei" and "Le2" in corpus. In the first half of this chapter, the author collected the HSK dynamic composition corpus in5years, and classified them with A-level and B-level. Both the errors and the correct use are analyzed. According to the statistics, we assumed that during the process of acquisition, the students acquire "Lei" first, then "Le2".The theory of Minimum Tree Hypothesis and using the hypothesis to explain this acquisition sequence is the emphasis in the second part.We designed a questionnaire to testify the acquisition order, and this constitutes Chapter4. Fist we introduce the background, objects, contents and results of the questionnaire and the results of the survey, then after using the SPSS software, we prove the rationality of the "minimum tree hypothesis".Some teaching methods are provided in the Fifth chapter. In line with the current teaching materials of "Lei" and "Le2" as well as the results of corpus investigation and questionnaire test, we put forward that teaching methods should be used in teaching and acquisition and the learning strategies should also be paid attention to.
