A Study on Acquisition of English Preposition in by Chinese Non-English Major Students Under the Principled-Polysemy Model

English preposition is one of difficult points in second language acquisition.This paper analyzes the differences of the senses of preposition in between Chinese non-English major students and native English students based on corpus from a perspective of cognitive linguistics.The study has found that Chinese non-English major students overuse the prototypical semantic entries,the low-level metaphorical entries and certain fixed phrases of in,without the diversity in using other metaphorical meanings.Through systematic analysis of the selected data,we think that the non-correspondence of prepositional semantic categories between English and Chinese caused by different conceptualizations is the main cause of this deviation.
