I. Safety on the way to school 1. Common sense of walking safety Every student must keep in mind the following common sense of walking safety: When the signal of the command light is green, let pedestrians pass; When the yellow light is on, pedestrians are not allowed to pass, but pedestrians who have entered the sidewalk can continue to pass; When the red light is on, pedestrians are not allowed to pass; When the yellow light flashes, pedestrians must pass under the principle of ensuring safety. When the crosswalk signal light is green, pedestrians are allowed to pass through the crosswalk; When the green light flashes, pedestrians are not allowed to enter the crosswalk, and those who have entered the crosswalk can continue to pass; When the red light is on, pedestrians are not allowed to enter the crosswalk. The regulations that pedestrians must abide by pedestrians must walk on the sidewalk, and if there is no sidewalk, walk on the right; Crossing the road requires a crosswalk; When crossing a crosswalk controlled by traffic signals, you must abide by the provisions of the signals; When passing the sidewalk without traffic signal control, look around, pay attention to the traffic, and don't chase or run; If there is no crosswalk, you must go straight through, and vehicles are not allowed to cross suddenly when approaching; Anyone who takes the overpass or underground passage must take the overpass or underground passage; It is not allowed to climb guardrails and fences along and in the middle of roads, and it is not allowed to push, chase, forcibly stop or throw vehicles on roads. What are the most dangerous situations when walking? (1) It's dangerous to cross the road. (2) Walking sideways in groups of three or five on non-sidewalks is the most prone to traffic accidents. (3) After the rush hour, there are fewer cars on the road, because there are fewer cars and fewer people on the road. Paralysis plus paralysis equals danger. (4) Walk with one heart and two minds, read while walking, or think while walking, or chat while walking, and play while walking ... In this way, the car may not hit you, but you will hit the car yourself, so it is also very dangerous. 2. Riding safety (1)/kloc-Children under 0/2 cannot ride on the road. This is stipulated by the traffic rules. (2) Riding without an umbrella. (3) Don't get rid of riding a bike. (4) Don't take people by bike. (5) Don't take the "patient" car. (6) Don't ride too fast. (7) Do not grab the road with motor vehicles. (8) Ride in parallel. Last but not least, don't ride a bike in bad weather, such as thunderstorm, typhoon, snow or frozen snow. 3. Safe ride (1) Look at which bus it is before you get on the bus, because when the bus stops, there are often several cars on the same platform, and it is easy to get on the wrong bus because you are in a hurry. (2) Stop the car and then get off. When you get on the bus, put your schoolbag on your chest to avoid it being squeezed out or run over by the door. (3) After getting on the bus, don't crowd at the door, go inside, stand firm when you see an empty place, grab the handrail, and don't let your head, hands and body stick out of the window, otherwise it will easily lead to injury accidents. (4) Respect the old and love the young, be polite to others, and take the initiative to give up your seat when you see the old, weak, sick and disabled pregnant women. (5) Don't read books when riding a bike, otherwise it will damage your eyes. Second, online safety education is weak, and online content needs to be graded. In recent years, young netizens in China have developed very rapidly. As of June 5438+ 10, 2002, the number of netizens under the age of 24 in China has reached17.35 million, and the Internet has become an important platform for young people to learn knowledge, exchange ideas and have fun. The network is like a double-edged sword, which enhances the communication and exchange between teenagers and the outside world, but some of the bad content is also very easy to hurt teenagers. This is manifested in the following aspects: many teenagers browse unhealthy content such as pornography and violence online and indulge in vulgar online chat. The characteristics of "no time difference and zero distance" on the network make the bad content spread around the world at an unprecedented speed, and the bad content on the network may even cause physical harm to teenagers. "Internet addiction" is a medical term that only appeared in recent years. Patients who rely too much on the internet and even like drinking and smoking will have symptoms such as listlessness and physical discomfort after getting off the internet. It is one of the follow-up research topics of China Modern Distance Education Standardization Committee to formulate online education content grading standards suitable for China's national conditions. In the process of participating in this study, the author conducted a questionnaire survey on 60 students and 40 teachers aged 8-24 in Shanghai in March 2002, and found some problems that people neglected in the past. There are temporal and spatial differences between teachers and students surfing the Internet. Students mainly surf the Internet at home and Internet cafes, while teachers mainly surf the Internet at school and home. None of the interviewed teachers really went to the Internet cafe to surf the Internet. Surfing the Internet in Internet cafes takes up a large part of students' time. Without the supervision of teachers and parents, the chaotic management of internet cafes will inevitably make students easily exposed to bad online content. Differences between teachers and students' cognition and tendentiousness of bad content on the Internet. Many students have inadvertently browsed the bad content. Comparatively speaking, most teachers have only heard of it, and nearly half of them don't know that there is bad content on the Internet. When the author conducted a questionnaire survey on teachers, many teachers said that they "don't understand at all", and students' cognition of bad content on the Internet is much higher than that of teachers. In the questionnaire, the author lists the laws, organizations, activities or events related to online content classification and filtering in China, mainly to understand the understanding of teachers and students. It was a pity that most students and teachers knew nothing about it. At the same time, most teenagers are indifferent to browsing pornographic websites. It shows that at present, teenagers generally lack internet safety awareness, and our internet safety education for teenagers is still quite weak. From this point of view, it is not only important but also necessary to filter the bad content on the Internet. The practice of foreign countries, Hong Kong, Macao and Taiwan proves that the hierarchical filtering of network content is a systematic project, which cannot rely solely on technology, but more importantly, policies, regulations and social education. Perfect policies and regulations, extensive social education and easy-to-use filtering products are the perfect combination to purify the network environment. The content supervision of traditional media can no longer meet the requirements of Internet development. Adopting content grading is a global development trend. No matter policies and regulations, social education or filtering technology, their common basis is grading standards, but unfortunately, China has not yet established its own content grading standards, which has caused a series of problems: for example, many teachers and parents themselves are not clear about the definitions of "pornography" and "sex science", and it is difficult to guide teenagers correctly; For another example, many lawless elements use the "gray zone" of the law to "edge the ball", and law enforcement departments will inevitably lead to many unnecessary disputes based on their own subjective judgments; For another example, domestic filter products use foreign standards, or they are developed by themselves, so it is difficult to promote them on a large scale, which leads to the filter products being "praised but not well-received". Just as there is industrial pollution in industrial society, there is "information pollution" in information society. On the internet, "junk information" and "information smog" can be seen everywhere, and harmful information, outdated information and "gray information" are full of our vision. It's time to say "no" to the bad content on the Internet. There has been a lot of research and practice on the construction of network content grading standards abroad. Taiwan Province Province, China also took the lead in completing the localization of online content grading standards abroad, but Chinese mainland is still in its infancy. China, with a population of 654.38+0.2 billion, should play its due role in this invisible global defense war. It is imperative to establish China's own grading standards for network content to conform to the trend of the times! 1. Healthy psychology is closely related to one's own safety. Such a tragedy happened in Beijing. A student with excellent academic performance, a girl who has always been the first in her class from grade one to grade six in primary school, has been in a dead end because she failed the math exam in grade one of senior high school. This tragedy warns us that we must pay attention to children's mental health. Nowadays, most children are only children, and parents generally attach great importance to their children's physical health, but often ignore their mental health. The student in the above tragedy is healthy, but mentally ill, afraid of facing setbacks, and has poor psychological endurance, which leads to her pessimism and despair. A mentally healthy child should have mixed feelings, be indifferent to humiliation, win without arrogance and lose without grace, be modest and humble, and have a stable, optimistic, enthusiastic and upward positive mood. A healthy spirit resides in a healthy body. Some students often feel uncomfortable in the examination room (such as dizziness. Stomach pain, limb trembling, etc. ), some because of poor physical fitness, some because of nervous exams. A healthy mind is the spiritual pillar of a healthy body. As the saying goes, "Smile, you are ten years younger", which is the truth. Good living habits, orderly life and stable environment are the prerequisites to ensure mental health. It is necessary to arrange the study time and weight reasonably, and at the same time, arrange entertainment and sports activities appropriately, so that the child's brain and nervous system can be relaxed, alternated and updated, thus ensuring the child's physical and mental development. Psychology and health are closely related, and we need a healthy body and mind. It requires us to live a moderate and orderly life. 2. How to improve psychological quality (1), establish a correct fear of life, keep an open mind at all times, improve the tolerance of psychological conflicts and setbacks, and love life and learning. (2) Fully understand yourself, correctly evaluate yourself, and be self-aware, without inferiority or conceit. (3) Make friends actively, be tolerant of others, be good at exchanging thoughts and feelings with others, help each other and learn from each other. (4) Actively cultivate your hobbies, such as playing chess, painting and calligraphy, taking part in beneficial recreational activities and actively participating in various sports activities. (5) Read more excellent literary and artistic works, such as How Steel was Tempered, Red Rock, etc., to cultivate sentiment and set up lofty ideals. (6) Learn to think, love to use your head, learn to comprehensively analyze complex problems, and be psychologically prepared for setbacks. (7) Parents don't spoil their children, they don't indulge their children excessively from childhood, and they don't make their children develop willful, self-centered bad habits and bad temper. (8) Let the children take part in the labor, even if they are injured in the labor, don't stop. Let children learn lessons and receive hard training. (9) To educate children to respect others, we must first respect elders and teachers, educate children to know how to respect the fruits of others' labor, and then ask children to care for property and cultivate the quality of diligence and thrift. 3. Cultivate the confidence and ability to overcome difficulties. Let children fully realize that it is impossible to succeed in various activities and studies. First of all, we should sweep away the fear of difficulties, cheer up, be mentally prepared to fight them at any time, despise them, and don't regard them as terrible or incompetent. There are difficulties in front of the strong, and there are no difficulties at all. What do you do? There has never been a smooth sailing. Difficulties always yield to indomitable and unwilling people.
