Textbooks are still irreplaceable and effective basic teaching tools. The simultaneous launch of teaching materials, CD-ROMs and online courses will help to broaden the teaching content and make the teaching content start from teaching materials and extend to the diversified information world through the Internet. The simultaneous introduction of teaching materials, CD-ROMs and online courses will help teachers to change their thinking and update the means of teaching and learning, so that the traditional "perfusion teaching" will gradually evolve into self-selected and participatory teaching. The simultaneous launch of textbooks, CDs and online courses will lead to the change of teaching mode, which can not only realize real-time synchronous learning under the guidance of teachers, but also realize non-real-time self-study under the guidance of teaching plans, and also realize the use of e-mail and online forums.

New Horizon College English not only inherits the fine tradition of traditional classroom teaching, but also has many advantages of online courses: both the delivery of teaching content and the management module of students' studies; It can not only track the process of students' learning and practice, but also automatically record their learning situation and provide inquiries about their usual academic performance. In addition, online courses also provide teachers with a question bank and tools and environment for implementing exams. New Horizon College English makes full use of real-time and different interactive tools on the Internet, and makes its own online discussion forum and email and mailing list system in online courseware, so that students can interact and learn in groups conveniently and quickly on the New Horizon College English website. However, all this is only an extension, supplement and strengthening of classroom teaching, and it is definitely not a substitute for classroom teaching. Face-to-face classroom teaching is still an important means of teacher-student interaction. With the increasing content of online courses, teachers should appropriately reduce the repeated explanation of the content, and at the same time strengthen classroom teaching and counseling in the form of face-to-face teaching.
