This is an empirical research on network-based teaching approach. By adopting the theory of autonomy, we redesigned the class arrangement. After the research was carried out for three months, a questionnaire was designed to learn of the student's attitude change towards the learning of English. The results show that over 80% of the students agree with the network-based teaching approach. They especially like the teaching of listening and speaking. Students have a stronger motivation than before and are more interested in learning English. We also analyzed the students' CET4 scores, and found the experimental group made more progress than the control group. All these are of great value to our further research.
