在大学英语课堂上要求学生做事先有准备的专题发言是很常见的活跃气氛的方法。它能提高学生的英语学习自主性,使学生有机会成为课堂的中心。关于专题发言笔者做过两次问卷调查。在第一次问卷调查之后,做了一些调整:采用演示文稿来帮助学生表达和理解专题发言。第二次问卷调查的结果有所好转。笔者认为在专题发言中应鼓励学生“发言”而不是“读稿子”。 Requiring students to do well-prepared speeches in college English classes is a very common and lively way. It enhances student autonomy in English learning and gives students the opportunity to become the center of the class. About the keynote speech I have done two surveys. After the first questionnaire, a few adjustments were made: use presentations to help students express and understand the topic. The results of the second survey have improved. The author believes that students should be encouraged to “speak” instead of “read manuscripts” in their speeches.
