The teacher assigned each study group the task of English cooperative learning, and each group discussed according to the assigned task. Each member of the group speaks freely, and the recorder is responsible for recording and sorting out the discussion. This link is the most important part of cooperative learning, and it also takes the most time. The main contents of the group discussion are: discussing the topics and illustrations of the text; Discuss the background, paragraphs, details, famous sayings and epigrams, genre and writing characteristics of the text; Discuss difficult sentences, long sentences, key sentences and words in the text; Discuss the background of the article, the author's attitude and viewpoint. "Discussion" is helpful to cultivate students' reasoning and judgment ability in the process of English understanding.

The ability to break through and how to express your ideas. The topic of discussion should be open, and sometimes there will be great differences of opinion on some social issues. This can form a very strong research atmosphere, enhance students' curiosity, and be more conducive to students' all-round development.
