培养训练学生的解题能力离不开作业，作业本是学生用来复习、巩固、消化所学知识的过程，但令教师感到头痛的是学生不动脑思考，抄袭别人的作业。我在初三一个班做了调查，情况大致分为三类：（１）不肯学不会做者占２０％；（２）学习浮躁懒得做者占６０％；（３）不相信自己 The ability to solve students’ problems in training is inseparable from homework. The homework is a process that students use to review, consolidate, and digest what they have learned. However, what causes teachers to feel headaches is that students do not think and copy their work. I did a survey in one class in the third grade. The situation was roughly divided into three categories: (1) 20% would not do without learning; (2) 60% would be too lazy to learn; (3) I did not believe in myself.
