Dear teachers and classmates: Good morning, everyone! Students will sing songs such as "I wish you peace" and "Life is safe and good" to pray for success and peace; The students also understood the reflection on life contained in the words "Peace is bliss" and "Peace is gold". Students also express their best wishes to their parents, classmates and friends with auspicious words such as "peace, health, happiness and smoothness". Campus safety involves more than 20 kinds of hidden dangers in teenagers' life and study: food poisoning, sports injury, the safety of online friends, traffic accidents, fire hazards, drowning, drug hazards and so on. It is understood that about 1.6 million primary and secondary school students die abnormally every year in China: on average, more than 40 primary and secondary school students die from safety accidents, food poisoning, drowning and suicide. That is to say, almost every day, a class of students is "disappearing". At present, there are many casualties caused by ideological, psychological and behavioral deviations among middle school students, which exposes the common security risks in students' ideological, psychological and behavioral aspects. One by one, the tragedies that are shocking and intertwined with blood and tears can't help but make people sigh and have a lingering fear, and also sound a security alarm for us. "Life", what a vivid word; "Safety", an ancient topic; What a wonderful state of happiness. Student: One person is safe and the whole family is happy; Life first, safety first; Safety first, prevention first. Only in safety can life keep its vitality forever, and only in safety can happiness keep its charm forever. On the issue of security, we should not be careless and take chances. On the safety issue, we should take precautions first, be vigilant first, be alert ideologically, abide by the rules, and be cautious in action; Must establish a high degree of safety awareness, everyone stresses safety, always stresses safety, and stresses safety in everything; It is necessary to build a great wall of security in thought, behavior and life. A healthy person, if addicted to the spiritual opium of bad books and online games, sucks every day and everywhere, and even can't help but be distracted and think in class; In the middle of the night, I couldn't help climbing over the wall and going to the internet cafe for a night. If he falls in love with the lingering feelings of boys and girls too early, he will find sorrow and hatred for no reason, be crazy and stupid, and even be jealous and settle grievances in the wind. When he is angry, he is a beauty. This shows the safety of behavior. With such unsafe behavior, it is difficult to read a good book and read it smoothly. Whether it is personal safety, ideological safety or behavioral safety, there is a common feature, that is, the cruelty of the result. Traffic accidents, swimming and drowning accidents, accidental injuries in sports activities, and accidents in chasing and slapstick games during recess will all harm people's health, and in serious cases, they may endanger their lives. Their consequences are cruel. But ideological and moral imperfection and behavioral deviance are more terrible than physical imperfection. Mr. Cang Kejia wrote in the poem Some People: "Some people are alive and he is dead." I think, those who have lost their healthy spiritual pursuit, lost the correct direction of life, and have fresh bodies are not the products of incomplete thoughts? At best, this "product" can only be a machine that endlessly absorbs and digests the blood and sweat of parents, and can only become waste in the long river of social development, and even become a dangerous thing that harms social development. Dear teachers and classmates, we all live in an intimate relationship intertwined by family, morality, responsibility and obligation. Therefore, individuals are not just individuals. Everyone's present is connected with the future, everyone's own is connected with the family, and everyone's honor and disgrace are connected with the whole. For personal growth, for the happiness of family, for the integrity of honor and disgrace, let's build a safe Great Wall of thought, behavior and life together and be a good person. Only good people can be safe all their lives; I wish good people a safe life.
