摘要：Relation between accuracy and fluency has always been an endless topic in foreign language teaching. Their relation is the most essential linguistic behavior in classroom teaching --- error-correction being connected together. Traditional behaviorist teaching and communicative approach can not resolve this issue. Interlanguage theory proposed in 1970s provides strong theoretical direction. In this text, the author looks back to history of error-correction concept, illustrates interlanguage theory, and reveals value of interlanguage theory in accuracy and fluency.
