摘要

This article mainly talks about the role of input,interaction,and output in the second language acquisition.Input is believed as a trigger for learners’language learning.And the process from input to output is interaction.Through interaction,language learners can negotiate the meaning with the interlocutor and narrow down the gap between the target language and their own.All the hard work made in interaction is to produce output,which includes three functions:noticing function,hypothesistesting function,and metalinguistic function.Some teaching examples are shown to testify the hypothesis and its function in the process of second language acquisition.
