Applied to real-life teaching, Krashen＇s theory helps us to find the causes of top students＇ halt of acquisition in oral English class--that is, insufficient and inappropriate input in listening, speaking and reading.

He mentioned the language as a form of ＂doing＂ rather than a form of ＂knowing＂. He believes that language is what it is because it has to serve certain function. In other words, social demands on language have helped to shape its structure. This theory distinguishes linguistic behavior potential from actual linguistic behavior. That means the speaker can do many things in certain language： making an invitation, expressing hope, inquiry, agreement, refuse and etc. Therefore EFL teaching is to develop the abilities to communicate with others, that is, listening, speaking, reading, writing and translating.
