The benefits are: The benefits brought by the Internet to human beings are countless. The emergence of the Internet is a symbol of the progress of modern society and the development of science and technology. Illiteracy in the modern sense no longer refers to those who cannot read, but to those who do not understand computers and are out of the information age. In ancient times when science was underdeveloped, people once imagined that they could know everything about the world without leaving home. Today, the high speed of information has turned this fantasy into reality. As a primary school student in the 21st century, can we still only read the books of sages and ignore world affairs? We believe that there are many benefits to the Internet. The Internet can broaden our horizons, provide us with the freedom to communicate, make friends, and succeed in playing games. It allows us to know that we must constantly seek new ideas. If we win, we will have success. A sense of accomplishment. First, primary school students’ access to the Internet is helpful for early intellectual development. The cooperation between the ten fingers and the computer, and the child's use of the various functions of the computer network, help improve the child's intelligence, skills and intelligence, and intelligence, skills and intelligence are the three major elements that reflect human quality. Therefore, access to the Internet for primary and secondary school students is not only very necessary, but also has great benefits as long as it is properly guided and controlled. Secondly, surfing the Internet helps expand children's knowledge areas and acquire a wide range of new knowledge through the Internet. For a long time, we have paid more attention to the cultivation of specialized talents but neglected the integration of various knowledge. Therefore, it is difficult to improve the quality education strategy. In many fields, there is a lack of new comprehensive humanities scholars, which directly affects the development of various industries. Therefore, cultivating our ability to combine a variety of knowledge from an early age not only helps improve quality education, but is also of great significance to the talent strategy in the 21st century. In addition, the increase in the proportion of the Internet population will help accelerate the process of social informatization, and this process plays a very important role in economic development and social progress. By sending emails online, we can establish awareness of electronic correspondence, e-commerce, and electronic writing from an early age, which can save a lot of wood pulp paper and improve environmental protection. As the future of our motherland, we can establish an awareness of e-commerce and make use of electronic currency. The improvement of awareness is an important indicator of the quality of the entire nation. It will also help promote the process of electronic currency and improve the quality of the entire nation. Learning computers well can also help stimulate our creativity. Third, primary school students can access a lot of rich resources and information online. The Internet is also a good teacher. With the development of science and technology, computers will become more and more advanced and their uses will become more and more widespread. Its emergence has brought us many changes. People can write accurately using computer calculations. These are the benefits of going online. The disadvantages are: Pay attention to "computer disease" A computer disease adds three major symptoms One of the symptoms: memory loss Research shows that not only the elderly, but also many young people in their 20s are now facing the problem of memory loss. Experts point out that this is because the brain is saturated with too much secondary information, and the culprit is the computer. Research shows that today's young people are becoming stupid. The reason is simple, play computer. A Japanese survey shows that more and more young people aged 16 to 30 are increasingly dependent on information technology. In addition to causing physical damage, they may also cause migraines, memory loss, restlessness and concentration. Inability to concentrate. People suffering from memory loss complain that they cannot remember names, things they have written, dates, and in some cases have to give up their jobs.

For people who have used computers for a long time, especially those who are accustomed to Pinyin input method, they often find that after getting used to using computers, they often cannot remember how to write some words when writing with a pen. Experts believe , which is suffering from "writing amnesia". At present, computers are becoming more and more popular in life, and writing with a pen seems to have become a thing of the last century. However, due to a long-term lack of writing exercises, many computer users, especially adults, rely on computers for long-term writing, which can easily lead to a decline in writing ability. , feeling unfamiliar with some commonly used common words. Not only has the level of calligraphy declined, but the phenomenon of not being able to spell but not writing is also increasingly common. Psychological and physiological research shows that writing training is crucial to cultivating thinking and forming good behaviors. Writing stroke by stroke with your hands can form a special imprint on the language center system of the brain, and it has a great impact on people's will, endurance, and perseverance. And the stabilizing function of the nervous system is also essential training. Typing on a computer will not form such an imprint, which will cause difficulty in identifying abstract meanings.

Therefore, although many people are good at typing on computers, they lack the necessary abstract thinking ability in their brains, causing certain obstacles in logic and language functions. Symptom Three: Sympathetic Nerve Disorders: Dizziness, insomnia, body aches, dry mouth... People who use computers for a long time will encounter this situation. In modern society, computers have become an indispensable tool for people's lives and work, but they have also increasingly become a "double-edged sword": while it brings people a lot of convenience, it also brings some pain. Experts believe , the above symptoms all belong to the typical "stress syndrome" of computer users. B. Seven Daily Attentions for Computer Users □ Change of name: "Computer disease" often forms slowly, is not explosive, and does not cause obvious harm to the body. It is most easily ignored by people.
