俗话说：“好的开始，等于成功了一半”。教师如果将课的开头设计得新颖、有趣，就能在课刚刚开始的时候紧紧抓住学生，使全班的注意力凝聚在一起，引向即将进行的教课内容。引人入胜的开头还能强烈地激发学生的学习热情，使其兴趣不断提高，这就为整节课的顺利进行打下了良好 As the saying goes: “A good start equals half of success.” If the teacher designs the beginning of the class to be novel and interesting, he can firmly grasp the student at the beginning of the class, so that the attention of the whole class can be brought together and lead to the content of the upcoming teaching. The fascinating opening can also strongly stimulate the students’ enthusiasm for learning and their interest in continuous improvement, which lays a good foundation for the smooth running of the entire class.
