| Higher Vocational Education (HVE) is an important component of higher education in our country. The English Curriculum Standard of HVE considers promoting the students' reading comprehension as one of the most important goals in English teaching. However, In EFL teaching of HVE, many teachers do not know much about the advanced teaching approach for lack of training and are still employing the traditional way of teaching in reading class, which does not benefit the students and is not an agreement with the Basic Requirements for HVE English Course.Task-based CL emphasizes the importance of education as a vehicle for teaching citizens to live cooperatively in a social democracy and teachers are not the only sources of knowledge and students should be able to help each other and learn in an interdependent way. Major reviews of cooperative learning research have shown that cooperative learning leads to common progress, higher academic achievement, better communication skills, increased motivation toward learning, higher self-esteem and self-confidence. The heart of cooperative learning is student-centered. Therefore, task-based CL can overcome the shortcomings in traditional teaching models, and the goal of improving reading comprehension can be achieved for the teachers of reading by realizing the mental process of reading comprehension and how prior knowledge can enhance a reader's interaction with the text through CL.This thesis consists of six parts.
