Internet to gain knowledge. However, it is difficult for students to have the perseverance to continue learning. The focus of teachers' work will shift to accompanying, supervising, checking, and helping students use the Internet. Teachers must constantly update their knowledge structure.

For teachers, current textbooks are more conducive to learning, but the role of teachers themselves has not changed. Therefore, the key issue is to enable teachers to learn to teach with new textbooks through the supply of high-quality online courses and the establishment of a teaching and research mechanism.
