Exploration of the Combination of Online and Offline Teaching of Undergraduate Computer English

In the undergraduate computer English teaching, it is found that the prior knowledge base of undergraduates is uneven, and the cognition of professional English terms of related nouns is different, which brings difficulties to the teaching of this course, resulting in poor teaching effect, and it is necessary to explain the knowledge before it can be carried out in the follow-up teaching. Therefore, the online platform is used to interact with students in real time during the course to ensure that the students' online rate and concentration in the classroom are high, improve the teaching efficiency, and promote the improvement of students' thinking and professional English skills.
