This papar concludesand analyzes the gathered materials to give a full description of how frequency effects inthe area of language acquisition. The whole article includes three major part: Firstly, ittends to look back to the developmental path of frequency effects of its highs and lows anddecribes the content of frequency effects. The second part brings together the empiricalstudies of input frequency and out frequency. The third part will presents a picture of theco-factors of frequency in language acquisition and summarizes several solutions to aid theteaching and learning a foreign language. This paper is a contribution to the literature oflanguage acquisition and the theories of language teaching and learning, and ends with alookout for the future direction of the relevant studies at home.
