500 words (1) Life is the best thing in the world. Moving like a flower in a mirror is easy to wither, and bright as clear water and bright moon is fragile. The glory of life is only one step away from fragments, which further shows that life needs us to cherish and care more, and it is very important to pay attention to safety.
Now, with the development of science and technology, the Internet, a new thing, came into being. However, while it brings convenience and enriches human life, it also brings endless troubles to human beings. In particular, the problem of teenagers' internet addiction has aroused great concern in society. How many teenagers neglect their studies because they are obsessed with the internet, even stay out at night, or even die of overwork in internet cafes, which not only affects the healthy growth of many students, but also brings pain to countless families and social stability. Network is a double-edged sword, so we should pay attention to network security, cherish youth and stay away from network harm.
Negative Effects of Internet: For Teenagers? Three views? Form a potential threat; Internet has changed the interpersonal relationship and lifestyle of teenagers in their work and life. Internet access is a self-centered lifestyle of teenagers, with weak collective consciousness and rampant individualism. This kind of rubbish will weaken teenagers' ideological and moral consciousness, pollute teenagers' hearts and mislead teenagers' behavior. The concealment of the network leads to the increase of immoral behavior and illegal and criminal behavior of teenagers. In addition, the imperfect legal system on the internet also gives teenagers the opportunity to commit crimes.
In fact, the awareness of life safety we want to establish is not only network security, but also anti-abduction and anti-fraud security. They are reminding us: cherish life, safety first. Caring for life can't be just empty rhetoric. Did you wake up after losing it? What should we do in the future? shouldn't it be more thought-provoking
Ostrovsky, the author of How Steel Should Be Tempered, once said: The most precious thing in life is life, and life belongs to us only once? Students, let's join hands, establish a sense of safety, cherish our own lives and the lives of others, make our body and mind grow healthily, make our life full of laughter, make our campus full of vitality and make our future full of hope!
Network Security Composition 500 words (2) With the change of science and technology, computer networks are also widely used, and every household is using computer networks, but is computer networks beneficial or harmful? This problem has aroused the reaction of some primary school students and parents. Today, I want to talk about my own views.
In my opinion, computers are very harmful.
I remember at that time, my family had the first computer. I will often surf the internet, find information, chat with distant relatives with qq, communicate with relatives with qq mailbox and shop online, which is convenient and fast. I will often play small games to relieve study fatigue. Will not become? Nerd? .
But now, my parents have controlled my online time. Because I am addicted to computers for five or six hours a day, my eyesight is poor. Besides, I will often play games. Many games often require players to pay, and the information in some games will lead us to commit crimes and neglect our studies. Now, I want to tell you something unforgettable about me and the Internet.
At that time, my parents went out for two days. These two days, apart from eating and sleeping, they sat in front of the computer and played games. At that time, I was already fascinated by the game. It's really hard for me to quit the game suddenly. This game is an upgrade game or an endless upgrade, which leads me to upgrade and want to upgrade. In this way, I can't extricate myself in the online world, and even I charged the game with 10 yuan to speed up the upgrade. After my parents discovered my excessive behavior, they strictly restricted my online time and let me extricate myself from the game.
This is the story of me and the Internet. Everyone should remember that surfing the Internet can help you but it can also destroy you. You should pay attention to arrange your time reasonably, and don't let the network trap catch you firmly!
With the continuous development of the information superhighway, the role of the network is increasing day by day, and the network has penetrated into our lives. However, after the network enters thousands of households, it brings convenience to the society, but also brings harm to the society.
The harm is obvious. It is that some teenagers are addicted to online games. Don't look at this little online game, it's really harmful. Some students are addicted to online games in our class. Just give an example! ? Lele? (a pseudonym) turned out to be a? Seed player? However, he was addicted to online games in previous semesters, and his academic performance declined rapidly, becoming a middle class. Fortunately, this semester began, he turned over a new leaf and became a good student again.
This is right around us, in fact, it is more serious in the newspaper. Some people are addicted to online games and actually embark on the road of crime, robbery and murder.
In fact, there are still many disadvantages of online games: serious eyesight decline, rapid heartbeat and no intention to study and work.
Of course, you can't say that the Internet must be bad. It's like a kitchen knife. Although it can cut people, don't you use it to cut vegetables? Similarly, the network also has its good side.
The internet can make you relax. Can you really do it? A scholar knows what's going on in the world without going out? , can make our office more convenient, can let us talk with distant relatives and friends, really can be too much!
In short, there is no good or bad in the world. Technology, lucky money, internet. Its quality depends on everyone!
