This paper focuses on the current situation of the low completion rate of online preview tasks and analyzes its specific impacts on classroom interaction in college English: students' participation enthusiasm shows hierarchical decline, the interaction content lacks sufficient depth, and the classroom atmosphere as well as the teacher-student collaborative relationship are damaged. By optimizing task design, improving the supervision and incentive mechanism, and building a connection channel between preview and classroom teaching, this paper puts forward three types of implementable strategies, clarifies the core laws of "cognitive coordination", "goal alignment" and "bidirectional empowerment" between online preview tasks and classroom interaction, and provides practical references for improving the quality of classroom interaction in college English.
