Chapter Two Literature Review

2.1 Corpus Preposition Research Status
Corpus-based study is an approach to investigating language structure and use throughthe analysis of large databases of real language examples stored on computer. Issues amenableto corpus research include the meaning of words across registers, the distribution and functionof grammatical forms and categories, the investigation of lexico-grammatical associations(associations of specific words with particular grammatical constructions), the study ofdiscourse characteristics, register variation, and (when learner corpora are available) issues inlanguage acquisition and development. The research results are more accurate andconvincing on the basis of corpus.Preposition is one of the most active English vocabularies; it has been the difficulty ofour traditional teaching. Therefore, corpus-based preposition research has been a hot issue ofexperts and scholars in recent years.Chen Changyi concludes six common errors of Chinese English learners: omission,addition, and excessive use of English prepositions in the translation from Chinese to English,speech confusion, inappropriate analogy and wrong collation. In addition, according to theContrastive Analysis, Chen Changyi explores the reasons for these errors: mother tongueinterference and influence cause most of the errors and difficulties that Chinese Englishlearners make in the process of English learning and application. Chinese and English belongto two different language branches, so many differences exist in the pronunciation, grammarand vocabulary structure. Moreover, the culture differences between Anglo and Chinese Hannationality also exist, people's ideas and ways of thinking are totally different. Most of ourChinese English learners' language experience is Chinese. When they begin to leam English,they will consciously or unconsciously use Chinese language codes, grammar structure, evenforms of thinking and expression to influence their English learning. Therefore, errors aremade easily.

Preposition, is a word or group of words, such as in，from, to，out of and on behalf of，used before a noun or pronoun to show place, position, time or method. It is a part of speechused before noun phrases or other structures that equal to noun phrases to show therelationship between words. English does not have an advanced inflections, it effects the connection of words extensively. According to the statistics of the American famous Linguistics Cuime, there are 286 prepositions in English, nine of them are often used: at, of，for, on, in, to, from, with and by, occupy 92% use ratio of prepositions. Therefore, besidesthose common propositions, some verb participles can also be used as prepositions. With theaddition of preposition phrases, such as regardless of, take on, the number of prepositions islarger. Chinese prepositions have so many differences with English prepositions; therefore,Chinese English learners have a huge challenge to leam English well.Preposition is an important part of speech in English vocabulary; some even say thatpreposition is the language of English.
