| In this paper,based on the collection of modern Chinese Dictionary(7th edition)and syllabus of Chinese level vocabulary and Chinese character level,the author takes "Gen","He","Tong","Yi","Yu" and "Yin wei" as the research object,investigates the studying situation of Korean students and puts forward teaching suggestions.I hoped that it will be helpful for the overseas students represented by Korean students to study the preposition-conjunction words well.The paper is divided into five parts:In the first part:this part expounds the reason for choosing the topic,sorts out the current situation of the research on the preposition-conjunction words and introduces the research scope,theoretical methods and the source of corpus;In the second part:the corpus is used to investigate the studying situation of Korean students on preposition-conjunction words.The result shows that biased types of preposition-conjunction words include:misuse,omission,addition,ordering and other errors.Misuse covers the largest proportion of the errors,and omission is the second.The main reasons for the errors are the negative transfer of mother tongue,the negative transfer of target language knowledge and the impact of learning environment;In the third part:the author investigated the mistakes of misuse and omission by using questionnaire.It can be concluded that misuse and omission of preposition "Gen"may be the most serious.It’s mainly due to the misuse of preposition"Dui".In addition,this chapter analyzes the causes of errors from three aspects:the difficulty of Chinese ontology knowledge,the discrimination of the synonymous preposition and conjunction and teaching factors;In the fourth part:some suggestions based on the corpus and questionnaire are put forward for teachers and students;The fifth part:the conclusion summarizes the value and deficiency of this paper. |
