2. Making bilingual learning courseware
At present, many schools are implementing bilingual teaching, and using bilingual courseware can make up for the shortcomings of individual teachers' strong foreign language reading ability and weak listening and speaking ability. After class, students use bilingual learning courseware to re-understand the complex, abstract and boring professional content taught in English and master professional knowledge skillfully.

In the past, using multimedia to create dialogue teaching situations required different people, fearing that poor pronunciation would affect the teaching effect and quality.

It can change roles at any time, learn dialogue in the situation created by multimedia, and arouse students' enthusiasm and interest in learning English.
