传统的英语课堂学习沉闷、机械,学生缺乏自主性、参与性和愉快感,课堂学习效率低。因此,优化课堂教学,让学生在教师所创设的情境与交际活动中愉快、高效地学习,是提高英语课堂实效的有效途径之一。 Traditional English classroom learning is boring and mechanical. Students lack autonomy, participation and pleasure, and classroom learning is inefficient. Therefore, optimizing classroom teaching and letting students learn happily and effectively in the situations and communication activities created by the teachers is one of the effective ways to improve the effectiveness of the English classroom.
