Abstract: Based on the problems in college oral English teaching, such as insufficient training environment and motivation, lack of cross-cultural communication situations, decoupling of classroom teaching from practical application, and insufficient training of output skills, this paper combines the theories of language input hypothesis and output hypothesis, and adopts the precise blended teaching of “online input-offline output” to carry out oral English training practice. The results show that this new teaching model can not only enhance students' learning enthusiasm, but also improve their oral output ability through multi-modal online language input and oral training in face-to-face classroom.
