【答案解析】I strongly believe that class discussion can benefit students a lot, in terms of both learning and communication skills. Through class discussion, students can broaden their horizon by listening to different opinions expressed from different perspectives. Anyway, many heads are better than one. Also, we can strengthen our communication skills in this way, because we can learn how to express our ideas persuasively and accept others' opinions selectively. When we make a presentation, debate with other groups and conclude the whole discussion, we can make progress in public speaking.
