Hello, this is my critical letter to you: although I didn't copy my homework myself, I gave it to other students before I realized the seriousness of my mistake. The nature of the error is serious, which is contrary to the students' behavior. As a result, many interests have been damaged and the school has been badly affected. This kind of behavior is wrong, which in itself violates the principle of being a student. I just care about my own interests and temporary ideas, regardless of the teacher's feelings. This is also wrong. People are social people and can't just think about themselves. I am the classmate who expects me to answer. In doing so, I seem to be helping him, but in fact I am hurting him. Moreover, it is also disrespectful to teachers. Thirdly, my behavior has also caused a very bad influence on my classmates and damaged the image of the school. Students should learn from each other and promote each other, but my performance has brought a bad head to the students and is not conducive to the construction of the school's study style. At the same time, it also caused some damage to the image of the school. I gave my homework to other students, which is not really helping others, but also harming myself and my classmates. Homework is used to balance students' learning quality. No matter what the reason, it is very wrong to pass the answer to others or not to give it to others, which violates the principle of being a student. From the homework, we can see that we are weak in learning, but I help others cheat and teach the knowledge to the teacher selflessly. Now I have fully realized that my behavior not only didn't help my classmate, but also hurt him and cheated the teacher. Since I accepted the teacher's criticism and education, I have deeply realized the seriousness of this matter. The teacher's education shows that the teacher cares about me and loves me very much. Therefore, I will listen to my teacher in the future, fully understand the teacher's requirements for us, and ensure that similar things will not happen again. If other students don't know in the exam, I won't tell him, but take the initiative to teach him after the exam, which will not only help the teacher get the best grades, but also help him not to master the students who haven't studied, and help the teacher create an atmosphere of mutual learning for the class. I hope the teacher can give me a chance to turn over a new leaf. Teachers want us to be the pillars of society, so I will work harder in my future school study and life, not only to learn what teachers teach us well, but also to learn how to be a useful person to society, an upright person and a good student to comfort teachers.
