A Case Study On The Acquisition Of "de" By Egyptian Middle And Advanced Chinese Learners

Case studies from the perspective of dynamic system theroy focus on the time dimension and study the dynamic,non-linear and complexity of learners’ language system in real situations.Through longitudinal case study and backtracking,this paper classifies the usage of "de" from the pragmatic function,from the five categories of "de" of reverse highlighting partial modification,"de" of reverse highlighting the condition and agent of the action,De of reverse highlighting the action itself,De of reverse highlighting the unusual state and de within the vocabulary,This paper studies the Chinese development behavior of Egyptian middle and advanced Chinese learners using the word "de".Based on the analysis of the chat records of Chinese learners and the author in 124 weeks,this paper classifies the use of "de" by Chinese learners into four categories:correct use,less use,more use and wrong use.It is found that Chinese learners’ pragmatic errors in using the word "de" can be divided into four categories: 1)failure to grasp the pragmatic focus;2)Failure to understand multiple pragmatic functions of the same language form;3)The failure of word order arrangement that does not meet the requirements of Chinese Pragmatics;4)Pragmatic failure caused by neglecting the "economic" principle.In particular,there are many problems in the use of "Hui...De","Shi...De" and the function words "de" and "Le",which cause most errors.The Chinese development behavior of learners’ overall use of "de" is characterized by nonlinearity,dynamism and complexity.Through the above analysis,this paper holds that the teaching form of Chinese "de" should be flexible,teaching students in accordance with their aptitude,developing teaching resources,and paying attention to pragmatic teaching.Learners should also maintain continuous learning motivation and improve their Chinese expression ability after class.
