Mankind will enter the information age, and the network will be more and more strongly involved in our lives, getting closer and closer to our primary school students. Is it beneficial or necessarily great for primary school students to surf the Internet? We firmly believe that the advantages of primary school students surfing the Internet outweigh the disadvantages. I will expound our views from three aspects: 1. Necessity. This is an era of knowledge economy, information is expanding and exploding at an unprecedented speed, and the future world is the world of network. If China wants to keep pace with the times in this information world, as the main force in the 2 1 century, it must be able to adapt to this high-tech society more quickly, have the ability to obtain effective scientific information from the outside world quickly and timely, and have the ability to disseminate scientific information, which is scientific quality. And the Internet has just adapted to this requirement. Didn't Grandpa Deng Xiaoping say, "Computers should start with dolls"? 2. practicality. The resources of the online world are enjoyed, just like a cornucopia, an inexhaustible "golden mountain of wealth". Whoever works hard on this golden mountain will gain something. We can find learning materials from them at the fastest speed, learn more extracurricular knowledge, use the knowledge in class flexibly, promote the development of thinking and cultivate the creativity of primary school students. Surfing the internet can also transcend the time and space and economic restrictions and receive online education from prestigious schools. If you have any questions, you can always get the teacher's guidance through the Internet. Moreover, interactive learning, rich three-dimensional graphics display, language explanation and other multimedia content on the network make learning easy and interesting, which is beyond the reach of any textbook! Besides, the usage rate and content of English are the most on the Internet, accounting for 84% and 90% respectively, which will encourage us to learn English more actively. Is this not good? 3. Reality. The urgent task is to establish computer classrooms in every primary and secondary school, popularize network knowledge, promote primary school students to surf the Internet at home, and realize distance education and knowledge sharing, so as to cultivate primary school students' interest and awareness in learning and applying information technology and cultivate our ability to acquire, analyze and process information. Look around us again. The school website is depressed. Didn't Mr. Wang also suggest you visit the school website more? Isn't the website of the class in full swing? If the Internet is not good, why build these websites? Indeed, as a new thing, we believe that the network has some disadvantages, but primary school students, with the education of the school, the correct guidance of teachers and the guidance of parents, will certainly enable us to use the network as a tool with a correct attitude. 2 1 century will be the information age, and we will be the pillars of the future motherland. Understanding and mastering computer network knowledge is the most powerful weapon to break through the future information age. Let us believe that every effort we make today will eventually converge on the Shahui Tower and will eventually be rewarded. So I once again state our point of view: the advantages of primary school students surfing the Internet outweigh the disadvantages! (Refuted after the opponent's debate) The Internet has brought countless benefits to mankind. The appearance of Internet is a sign of the progress of modern society and the development of science and technology. Illiteracy in the modern sense no longer refers to those who can't read, but people who don't understand that computers are divorced from the information age. In ancient times when science was underdeveloped, people often fantasized that they could know what was going on in the world without leaving home. Now, the rapid spread of information has made this fantasy a reality. As a pupil of 2 1 century, can you still read only sage books and not know what's going on in the world? Another debater cited various examples to prove the disadvantages of the Internet to our primary school students. However, I want to say that everything will always have some disadvantages in the new stage. If we kill it just because of a little flaw, then we miss a lot of things that are indispensable now. Internet speed also has its advantages. Through the internet, we can keep abreast of some latest news. Through the Internet, we can travel all over the country's primary schools in just a few hours, and look up the materials we need in the online library. With the help of online information, we can finish our studies calmly and know the results immediately after the exam. If we have any questions, we can always ask the teacher for guidance by email. Take SARS, which impressed everyone the most. During SARS, some schools in Guangzhou and Beijing had to stop classes. In order to implement synchronous teaching, people invented online school. Every week, the teaching content of online schools is consistent with the progress of school courses, and we can receive comprehensive education from all over the country through the Internet. Is this not good? Because of the above viewpoints, we firmly believe that the advantages of surfing the Internet outweigh the disadvantages! How many amazing changes have taken place in the world since mankind entered 2 1 century. 1: Environmental pollution. This is the most direct and obvious disadvantage. The extinction of species is accelerating. This is caused by environmental pollution and human hunting. It is also a disadvantage of scientific and technological development. 3. Personal safety is increasingly insecure. There are now tens of thousands of crimes on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people are even more difficult to guard against. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction. Human's physical quality is not as good as before. With the development of science and technology, the appearance of vehicles such as air cars, trains and planes has greatly changed human daily life, and human beings no longer always rely on their own legs. Therefore, the physical quality of human beings cannot be compared with the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". However, if this situation continues to develop, it may make people's limbs atrophy and make people appear new forms. 5. All kinds of emerging germs appear constantly, and the lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of the virus, so that the development speed of science and technology has reached. ..

The continuous development and progress of society and the continuous innovation of science and technology have both advantages and disadvantages for mankind. Science is always a double-edged sword, which will bring convenience to human beings, but it will also make human beings pay something valuable.

However, even if the disadvantages outweigh the advantages, can you not develop science? No way! What is the difference between human society without science and monkeys before? What did you say?/Sorry?

Playing computer has both advantages and disadvantages.

Pro: 1. Playing computer games after working for a long time can relieve mental stress and relax.

If you don't talk about all computer games, it will be good for you. For example, printing articles, learning programming, doing online business, searching useful information online, understanding current affairs online and so on. In fact, computers have many advantages.

3. If you are a computer expert, making a flash or two and putting it on the website can not only improve your production ability, but also please everyone. Isn't it the best of both worlds?

Disadvantages: 1 Playing computer for a long time, the high-frequency radiation emitted by the computer is very harmful to the eyesight of the eyes.

2. If you turn on your computer just to play computer games, it will take too long and waste a lot of precious time.

3. And often staying in front of the computer will also lead to unsociable personality and disharmony, which will have an impact on people's body and mind.

Here are some of my experiences. Maybe you can use them. I want to encourage you.

1. In the great 2 1 century, people recognized three kinds of fools: smokers; Ignorant of computers; People who don't know music; Computers seem to have been integrated into everyone's world. Surfing the internet is another part of the computer, which means communicating with the outside world through the computer network. This technology is advanced and suitable for the society. Economic development. However, everything has advantages and disadvantages, and surfing the Internet is no exception.

Ok, now tell me about my online experience. Like most people, at first, surfing the Internet existed on the other side of the fog. I am fearless and ignorant of this high-tech and virtual world. Through online games, I have closely linked the Internet with myself. As a result, I became obsessed with this. Of course, at this time, parents will tell you to stop surfing the internet and concentrate on your studies, or tell you a few vivid stories to give up immediately. However, even if parents inculcate, it goes in one ear and out the other. Because infatuation can make you lose your way, you don't know what you need, what you pursue, what you will lose, but you are addicted to the illusory realm. This is the performance of most teenagers. In the long run, they will become introverted. Isolated. Negative, their grades will drop. Spend most of your time on the internet. This is also the reason why many parents don't agree with their children surfing the Internet. However, not all teenagers are in this situation. Experts have found that children who are prone to internet addiction mainly lack self-control. So for teenagers with strong self-control, they will make good use of the internet to study. Entertainment. Or communicate with the outside world. So as not to worry parents and teachers.

Next, let's talk about the benefits that the Internet brings to teenagers. Surfing the Internet, although in an unrealistic space, is very convenient. Brisk. Flexible functions allow us to increase our knowledge, swim in the ocean of knowledge and enjoy various forms of entertainment. For example, studying in an online virtual school, where you can also find the best teachers and get the most essential learning methods; You can also send an email to your relatives and friends on the occasion of the festival, which can represent your most sincere wishes. And this process is just that you gently press the enter key; Moreover, make friends through online chat rooms or BBS, participate in the discussion of social issues, express opinions and so on. The network has so many advantages that it is so popular.

However, the network still has shortcomings. The most obvious thing is that many students are addicted to online games. Chatting, neglecting studies, wasting time. Once addicted, the consequences are unimaginable. What's more, a small number of students have embarked on the road of crime because of surfing the Internet, and finally, they have left lifelong regrets. It can be described as follows: students' self-control is limited, and the attraction of the Internet is unlimited.

The pros and cons of things are so much. There are advantages and disadvantages, mainly depending on how you use it and how you grasp it. We should have a good understanding of these two aspects, make good use of them, and improve them, then it can really be regarded as a lot of benefits.

2. The rapid development of network technology provides strong support for middle school students to explore the increasingly broad network life space, and the network life becomes more colorful and full of vitality. Working online, reading books, shopping, making friends, entertaining, chatting, opening forums, talking about business, doing business, buying insurance, falling in love, finding a partner, going to court, seeking medical advice ... The tentacles of online life extend to all fields of human life. Network is the extension and expansion of human brain, a big world where people's spirit of freedom and independence is displayed and galloped, and a big stage where people's imagination leaps. The role of middle school students surfing the Internet is self-evident, which can be summarized as follows. .

& lt 1 & gt； It can broaden the horizons of middle school students, and there are a lot of educational information on the Internet, which is very helpful for middle school students to enter the society in the future. Through surfing the Internet, middle school students can keep abreast of current events and get all kinds of latest knowledge and information.

In Singapore, every school has a fixed time for students to surf the Internet for free and complete some schoolwork tasks through the Internet. Internet has become an important learning tool for middle school students.

Advantages and Disadvantages of Computer Games Pan Heguo of Fuzhou No.2 Middle School said that computer games, as an important part of social and cultural life, have penetrated into all aspects of people's lives. No matter you open newspapers, magazines, TV and radio, you can get all kinds of introductions, explanations and explanations about computer games.

This paper discusses the advantages and disadvantages of computer games for middle school students.

Middle school students are very nervous about their studies. Under the heavy academic burden, it is also very beneficial to have some entertainment to relax occasionally. The so-called study must be relaxed, always nervous, or in a state of high pressure for a long time.

For a student, both psychologically and physically, it has a great negative effect. Moreover, poor mental and physical state will lead to a decrease in learning efficiency, which is extremely unfavorable to learning. In this case, playing computer games occasionally can easily relax the tense mood and has a good regulating effect on the nerves that have been tense.

In addition, computer games not only have the functions of relaxing mood and adjusting mental state. Games are not just games. Appropriate computer games can improve the thinking ability of the brain and coordinate the cooperation between hands and eyes. In many games, your brain can be exercised. For example, RPG can exercise your reasoning ability about events and your ability to match many different data. And SLG games can exercise rational thinking well, because in SLG games, many events can achieve better results through mathematical modeling. Computer games can also exercise the proficiency of middle school students in operating the mouse and keyboard, just like Bill? As Gates said, the best teacher to learn computers is computer games. And computer games themselves are the best threshold for people to enter the computer world. As a modern middle school student, if you can't skillfully use computers, the future will only be an empty job. If middle school students don't touch games now, the internet will be developed in the future, and they may even lose the ability to communicate with others. What a terrible thing.

In addition, there is so-called virtual reality in computer games. For a middle school student, there must be many unpleasant things in life. Under the pressure of society, teachers and parents, if the depression in the heart is not vented in time, it will be extremely bad and may even affect people's life. In the virtual reality of computer games, this problem does not exist. Here, I am God! You can experience a feeling of complete relaxation and no worries, which is very conducive to venting your inner pressure.

As a culture, computer games can also bring a lot of information to students and provide them with writing materials. Fan fiction, for example, talked about his feelings of playing computer games. Writing more articles like this can also exercise his writing style well. Such an article is not boring at all, but emotional and completely true. ]
