Copying the answer to a question 40 times is really meaningless for learning mathematics. One of the purposes is to punish students for not completing the tasks assigned by teachers, to establish the authority of teachers, to make students awe, and the teaching methods are too low. It is better to think of other ways to stimulate students' interest in autonomous learning.

But for this kind of punishment, although students are reluctant, they should learn to accept it and finish it seriously, because there are often similar behaviors in society, some of which are punitive (for example, they will be punished to guide pedestrians at intersections for a period of time after crossing a red light), and some of which are productive (for example, the work on a factory assembly line), all of which simply perform the same action, so if you want to avoid doing this kind of thing. Before you become an authority, accepting and respecting authority is a life rule for you to learn to be a person and do things. Unless you work hard, become the authority of others and accept the awe of others.
