Mongolian Students' Errors In The Acquisition Of Related Chinese Prepositions Corresponding To "Instrumental Case" In Mongolian Language

With the increasing cooperation and exchanges between Mongolia and China in various fields,Chinese President Xi Jinping paid a successful friendly visit to Mongolia in 2014,and since then the two countries have established a comprehensive strategichou partnership of cooperation.Mongolia and China have entered a new period of friendly historical development,coupled with the peaceful rise of China in the world,more and more Mongolian students are studying in China,which objectively promotes the exchange between the two languages and cultures.In this context,this thesis chooses the acquisition errors of relevant Chinese prepositions corresponding to the Mongolian language"Instrumental case" as our research topic.First of all,we introduce eight noun cases used to express grammatical meaning in Mongolian.They are Nominative case,Genitive case,Dative locative case,Accusative case,Ablative case,Instrumental case,Comitative case,Directional case.These eight noun grammatical cases can only be expressed by prepositions in Chinese.After that,we focus on the relationship between "instrumental case" and Chinese preposition in Mongolian.They have both similarities and differences.The same point is that:1.Neither of them can act as a sentence component independently,nor can they answer questions separately.2.Can not be overlap 3.no dynamic auxiliary can be brought with"le"(ed),"guo"(have done).4.Both Chinese prepositions and Mongolian words "Instrumental case" can be used as objects in a sentence.The difference is that in Chinese,nouns that form prepositional phrases with prepositions are placed after prepositions,while in Mongolian,nouns in prepositional phrases are placed in front of Mongolian "case".And we find that Mongolian "instrumental case" can correspond to 12 prepositions in Chinese.We classify these words in the following:primary stage:yong,rang,jiao,genju;Intermediate stage:tongguo,anzhao,chen,ping;Advanced stage:yi,shun,jiang,lun.On this basis,this paper further studies the form and causes of errors in the acquisition of these 12 prepositions by Mongolian students.We find that the errors in the acquisition of these prepositions by Mongolia students are:misrepresentation>error>omission>error order.Then,this paper makes a deep analysis of the four errors of Mongolian students,and puts forward six reasons for Mongolian students' acquisition of 12 prepositional errors.They are:first,the essential differences between the two languages;second,the simplicity in form and the complexity of semantics in Mongolian;thirdly,the discreteness and polysemy of Chinese prepositions;fourth,fourth,the influence of "negative transfer of mother tongue";fifth,the reasons of teaching and teaching materials;and sixth,the factors of learners themselves.Finally,suggestions are made from the researchers,the compiling of teaching materials,teachers and teaching and we take "?" as an example to make a teaching experiment.
