I didn't bring my health certificate for reexamination.

I am your student: XXX. Today, I write this critical letter to you with guilt and regret, to show you my profound understanding of the bad behavior of smoking and my determination to never smoke again.

As early as when I stepped into the school gate, the teacher repeatedly stressed that all students should not smoke. I think it is necessary and necessary to make this written review to the teacher, so that I can deeply reflect on my mistakes.

Sorry, teacher! What I have committed is a serious matter of principle. I know, and the teacher is angry that I smoke. I also know that non-smoking is the most basic responsibility and obligation for students. But I didn't even do the most basic things. I thought calmly for a long time afterwards, and I gradually realized that I had to pay for my impulse. I was deeply shocked by the teacher's repeated teaching and serious expression, and also deeply realized the importance of this matter. Now, a big mistake has been made and I deeply regret it. After a profound review, I think there is a fatal mistake hidden in my mind: my ideological consciousness is not high and I don't respect others enough. In the future, I will respect teachers more and take important things seriously. Usually, the lifestyle is lazy. If it weren't for being too lazy, it wouldn't be like this. In order to better understand the mistakes, but also to convince teachers that students can really correct mistakes and ensure that they will not make mistakes again!

Now I think of my behavior at that time, and I am really annoyed and regretful. In the present situation, especially during the xx period (you can write about major inspections, 100-day activities, etc. ), it is extremely inappropriate for me to use this precious study time to come to XX. This kind of behavior not only makes the teacher/teacher disrespectful and irresponsible to our collective, but also makes us lax in our requirements and lack of constraints. This not only makes the teacher/teacher have a very bad impression on me, but also makes the teacher/teacher leave a very bad impression on our whole XX group, which makes our group lose face and team on campus. I made such a mistake when I was carrying out "…" (the name of a special activity, such as "100-day safety inspection") on campus, which greatly damaged our collective image. The fundamental reason is that I relaxed my requirements and lowered my standards on weekdays, which led me to make mistakes inadvertently, breaking the rules of the team/class and destroying the team.

I'm sorry for this behavior, I'm sorry for XX, … (write the leadership level or name, from high to low, it's best to write it all, but don't write it from high to low).

If I can learn from the backbone/class cadres as much as other students, be strict with myself and raise my standards, I think I won't make such a serious mistake.

There is no regret medicine in the world. It's no use talking. We can only take this lesson as a warning, this incident as a warning and this inspection as an opportunity. From now on, we should improve our own requirements, strengthen our self-discipline, strengthen our sense of responsibility, deepen our sense of collectivism honor, and strive to become students/students with excellent work style and practical study in the school and strive for our class/team.

Simply state the facts, say what you did, how you smoked, and how you were caught by the teacher because you saw others smoking handsome or something.

1\ Hazards of smoking. Smoking is bad for health, especially for middle school students. After burning cigarettes, 4700 compounds can be produced, and the most harmful substances in cigarette smoke are tar, nicotine and carbon monoxide. Tar can cause cancer; Nicotine can excite the central nervous system at low dose, but high-grade food can inhibit it, leading to vasospasm, hypertension, accelerated heart rate, increased cardiac oxygen demand and angina pectoris. After carbon monoxide enters the human body, the hemoglobin of rain and snow audience combines into carbon hemoglobin, which can cause hypoxia in human tissues and organs. Therefore, smoking is a serious health hazard. ! ! ! ! ! ! ! ! !

2. Smoking forms second-hand smoke, which affects the health of students and teachers. Secondhand smoke is one of the most extensive and harmful indoor air pollutants, which mainly comes from mainstream smoke exhaled by smokers and tributary smoke released by burning cigarette butts.

According to the experimental results, the impact of second-hand smoke on health is similar to that of smokers. For example, the incidence of lung cancer in a person who does not smoke himself but whose spouse smokes increases by 20% ~ 50%, and the infection rate of innocent people living in a polluted atmosphere containing environmental smoke is 20% ~ 30%.

According to the statistics of the World Health Organization, 53,000 people die from this "negative tobacco poisoning" every year.

3. Smoking may have a bad influence on other students, affecting the style of study, school spirit and class spirit of the whole class, which is not conducive to normal teaching activities and the healthy growth of students.

When you admit your mistake, you mean complete repentance. Study hard.

After this incident, after the criticism and education of my father, I deeply realized that I was wrong and decided to quit smoking.

So much, add some yourself.
