In order to study the advanced stage of Korean learners presentive expression experiments were carried out. The experimental subjects were divided into two groups, the experimental group of Korean subjects are: students in Graduate School of translation 10 people, reach the HSK6 level of the adult learners of 10 people, a total of 20 people, the control group is 20 Chinese people. Through the document survey, collected a total of 1200 cases of corpus, appeared in the process of learning the error type and the causes are analyzed, and then put forward the related teaching strategies and skills.
The experimental results show that the Chinese subjects expressed meaning when the widespread use of existential sentences, while Korean subjects mainly choose “V在+NP" structure, the existential sentences often take evasive strategies according to the nature of the error. There, can be roughly divided into the following categories: first, mistaking the existential preposition. The subject of sentence does not need to introduce Korean prepositions, but by the influence of mother tongue, habitually in the sentence first place word before the error with the preposition “在". Second, “V" is an intransitive verb, the subject is misplaced in before the verb, “V" is a transitive verb, error plus verb the agent. Third, there is the main general indefinite noun. No qualitative representation of noun phrases referring in a specific context, the hearer's heart, there is no specific meaning, but the speaker's heart has a specific reference object. The object stored in sentences is the main part of the transmission of information And as the unknown information, so specific and unspecified person or thing, but no qualitative Korean subjects did not realize the existential object, teachers should pay special attention to this.
