English writing is regarded as the most difficult task by Chinese EFL learners. Due to the existing problems in present college English writing instruction, teachers fail to provide effective guidance in students' writing process and students report a low level of motivation and confidence in writing tasks. Through purposeful reading discussions driven by writing tasks, students are provided with sufficient opportunities to receive language input. Reading-to-writing activities, based on output-driven hypothesis, help students consolidate and internalize linguistic and stylistic knowledge acquired in reading. This study mainly focuses on integrated reading-to-writing mode applied in teaching college English writing based on output-driven hypothesis, aiming at helping teachers guide students to improve their language proficiency so as to enhance the efficiency of writing.
