Abstract: Native language is one of the important factors influencing students’ second language acquisition.Researchers who focus on second language acquisition have made profound research and proposed many theoretical hypotheses.Based on the previous research results and by adopting contrastive analysis,this paper tries to make a relatively thorough analysis of this question in order to explore the influence of native language on SLA and thus construct a comprehensive theoretical framework to eliminate native language interference.

Key words: native language, second language acquisition, transfer, contrastive analysis, mother tongue interference
