In order to better understand and remember the courses to be learned, you gave us * * * * homework, but I didn't understand the teacher's painstaking efforts, so I apologize to the teacher. Therefore, I write this critical letter to you with 120,000 guilt and 120,000 regret, in order to show you that I hate the bad behavior of not finishing my homework and my determination not to make this mistake again. I have deeply realized the importance of this matter, so I have repeatedly told myself that we should take the homework assigned by the teacher as the top priority and don't live up to the teacher's painstaking efforts. For things that have not finished their homework, the serious consequences are as follows: 1. Let the teacher worry more about my study. 2. It has caused a bad influence among students. Because of my mistake, it may cause other students to follow suit, and it is also irresponsible to the parents of other students. Now, a big mistake has been made and I deeply regret it. After a profound review, I think the following fatal mistakes are hidden in my mind: 1, my ideological consciousness is low, and I pay serious attention to important issues. Even if there is understanding, it has not really been put into action. 2. The root cause of low ideological awareness is that I don't respect others enough. Imagine if I had more respect for my teacher, I would finish every homework assigned by my teacher on time. I decided to take the following personal rectification measures: 1. Submit a letter of criticism according to the teacher's requirements! Dig deep into the root of one's own ideological mistakes and find out the possible serious consequences. 2. Make a study plan and carefully complete every assignment assigned by the teacher. 3. Strengthen communication with classmates. Try to make progress with the whole class. Please ask the teacher to see my future performance. I promise that the above mistakes will not happen again. Student: Date
