Advantages and disadvantages of surfing the Internet 600 words With the development of the times, surfing the Internet has become a very common thing.

Whether adults or children, as long as they mention computers, they will think of surfing the Internet.

However, surfing the Internet is a "double-edged sword", which has both advantages and disadvantages.

I found some younger students surfing the Internet at home, mainly playing games.

Some middle school students often play all night, which is bad for their health and delays their studies.

I learned a true story from TV news: a middle school student is obsessed with playing online games. One day, he told his parents that he was doing homework at his classmate's house and might come home late.

At night 10, he called his parents again, saying it was too late, went to sleep at his classmate's house and told them his phone number.

The next morning, my parents were not at ease and dialed the phone. The person who answered the phone said it was an Internet cafe and said, "Yesterday, a middle school student surfed the Internet here and stayed up late at night.

"Parents immediately rushed over and saw their children sleeping soundly on the sofa.

I am really angry and distressed.

You see, he not only hurt his health, but also affected his study. He also lied and made his parents sad. It's really bad.

Therefore, some people think that primary and secondary school students lack willpower and are not allowed to surf the Internet.

However, many people are also in favor of surfing the Internet. Why? Because surfing the internet can bring convenience to people.

First of all, surfing the Internet is like walking into a multifunctional fast library.

As long as you enter a short phrase, the information you want will appear in front of us immediately, which is faster than looking up a book and gets more information. Internet has become an indispensable assistant in my study.

I am a composition committee member in my class. When I discuss organizing various Chinese activities and participating in debates with my classmates, I often look up information on the computer. Internet has become an indispensable helper in my work and life.

Secondly, you can read more and richer news online.

One of my classmates counted that there are dozens of times more news on the computer than on TV.

Besides, computers have other functions.

A good friend of mine said to me, "Her mother is in France. It is expensive and troublesome to send letters or make long-distance calls to her mother, so they always send emails or make video calls, which is quick and convenient.

Seeing this, how can you say that the Internet is not good? In fact, like other things, surfing the Internet has both advantages and disadvantages.

Surfing the Internet is a "double-edged sword". We use it to broaden our horizons and enrich our knowledge, but we must master the sense of proportion and not let the sharp side cut our hands.

This started in the sixth grade of primary school. I hope it helps you. ...

Advantages and disadvantages of online composition 1. The communication characteristics of computer network cause information flooding, and all kinds of information garbage will weaken the moral consciousness of teenagers.

Internet not only strengthens the consciousness of young global village villagers, but also weakens their national consciousness.

The so-called "new humans" on the Internet will find a strong international color in them, because the use of the Internet has crossed the boundaries of time and space, enhanced their awareness as villagers in the global village, and is conducive to their survival in an increasingly "integrated" world.

But this sense of "integration" is accompanied by the weakening of race and national consciousness, the weakening of national identity and the gradual dissolution of national identity.

In a sense, it is not conducive to the formation of patriotism.

The Internet has also had and will continue to have an impact on existing moral concepts and values.

According to the survey, 26.3% of people said that "the hacker's skills are superb and admirable? Quot 16.7% people think that "the behavior of hackers promotes the development of network technology", and 24.4% people say "it's hard to say".

Only 24.6% people made it clear that "the hacking industry is harmful to society and should be severely punished and tried to put an end to it".

2. The directness and visualization of network culture have a great influence on teenagers' way of thinking, which hinders the improvement of their comprehensive quality to some extent.

Undeniably, the richness of computer network information plays a positive role in broadening teenagers' horizons and helping them understand new things. However, with the explosion and pollution of information, all kinds of redundant information flowing on the network become "noise" that interferes with teenagers' choice of useful information, and computer networks occupy teenagers' reading and thinking time.

From 65438 to 0995, China Academy of Social Sciences conducted a survey on 4,845 teenagers in 9 provinces, municipalities and autonomous regions, and found that 40% of teenagers had no books except textbooks, only 36% had 50 books, and only 2% had more than 500 books.

The reduction of reading not only affects the balance of teenagers' knowledge structure, but also greatly damages their ability to use words.

Many teenagers are very skilled in computer operation, but they can't write beautiful Chinese characters and fluent compositions, and typos and sick sentences can be seen everywhere in the articles. This phenomenon is worrying.

3. The concealment of the Internet will lead to the increase of immoral behavior and illegal and criminal behavior of teenagers.

In the environment of one person and one computer, teenagers don't have to deal with others face to face, so there is no circle of acquaintances in traditional society to restrain people's behavior.

At the same time, network technology can make people's identity a string of characters on the computer, and anyone can communicate with people of different names, genders and ages without being noticed.

According to statistics, only about 1% of computer crimes have been discovered, and only 4% of this 1% will be prosecuted.

Just like a popular saying recently, "On the Internet, no one knows that you are a dog".

This leads to more and more immoral behaviors on the Internet.

According to a survey of five universities in Beijing, 12.5% people have obtained other people's emails, 9.8% people have consulted pornographic pictures or texts, 98.6% people have obtained other people's secrets and private letters, and 5.4% people have published unhealthy information.

In Taiwan Province Province, after a couple broke up, the man entered the online chat room as the woman, put her real phone number and address in it, and claimed to be an imaginary lover to vent his dissatisfaction with the woman's breakup.

The hidden characteristics of the network also make cyber crimes emerge one after another, and cases of infringement of intellectual property rights, malicious creation of computer viruses, hacker attacks and so on increase year by year. In recent years, the number of illegal intrusions by hackers in the United States has reached160,000, and the loss has reached $8 billion. The loss caused by global digital crime is even greater, * * * about1500 million.

In September 1 day, the people's daily news has been huge recently, * * * about1500 million dollars.

On September 1 day, People's Daily recently cracked an online fraud case. It happened on August 25th, and an amazing news appeared on the Internet: the president of Emulex Company, one of the largest network data equipment suppliers in the world, resigned, and the company's previously announced profits were greatly exaggerated.

As soon as the news was released, Emulex's share price plummeted 60% that day, with a total loss of $2.5 billion.

The maker of fake news is a 23-year-old young man who works in a website.

Previously, he bet others that Emulex's stock would fall.

As a result, he won $250,000 by such despicable means.

4. The virtual characteristics of the Internet will lead to the appearance of digital people and the dehumanization tendency of teenagers.

Because the network connects the sites in various places together, forming a virtual space.

In this way, there are actually two kinds of existence in the world, that is, social existence in the sense of territoriality and virtual social existence. There is a great contrast between the two, which leads many young people to escape from reality, refuse to return to the real world, suffer from Internet addiction syndrome and become videos.

At the same time, people rely more and more on the network when they ingest information, which makes them treat the whole human beings and the real society in a completely externalized, symbolic way and cold operating ethics. Communication between people is more difficult than before, and individuals will also have symptoms such as nervousness, loneliness and lack of emotion. Some even have personality disorder and interpersonal communication disorder, and they are just armchair strategists, unable to face the real society and form a "one-off". Quot Man-Machine-Symbol-Symbol-Machine-Man "communication form.

5. The globalization of Internet makes the spread of cultural network the main reason for the conflict between teenagers' outlook on life and values.

The global characteristics of the Internet will lead to confusion among teenagers.

Internet enables people to form a global media without regions and borders.

Due to technical reasons, there is no strict review of online content, which makes the internet full of useful and useless, right and wrong, advanced and backward information, and obscene, pornographic, violent and other ugly content is also widely spread online.

According to statistics, there are many reasons for people's fatigue. More than 0%, of which online yellow poison can be seen at any time.

These have caused the vague concept of right and wrong, the decline of moral consciousness, the weakening of social responsibility and the infringement of physical and mental health.

At the same time, the openness and global characteristics of the Internet have intensified the infiltration of western culture.

Nowadays, on the Internet, English content ...

The harm of surfing the internet. This composition is 600 words.

In today's society, the Internet has entered thousands of households.

Internet is more and more closely related to our life and study! People can browse the latest information on the internet through computers without leaving home.

However, some people say that the Internet is like a double-edged sword. I think this sentence is true at all.

With the progress of science and technology, the development speed of the Internet is getting faster and faster, and the information on the Internet is getting richer and richer.

I am both for and against surfing the Internet.

The reason why I am in favor of surfing the Internet is that there are abundant resources on the Internet. We can use the Internet to find information related to our study and work. We can also shop, watch movies and listen to songs online, which brings endless happiness to our lives.

I remember once I took the computer learning machine I just bought and wanted to download some materials, so I took the learning machine to my uncle's house and downloaded the materials I wanted to download from the website through the internet with my uncle's computer.

I heard from my uncle that he made many friends online with QQ.

The reason why I object to surfing the Internet is that the information on the Internet is very rich and complicated, with a lot of bad information, and most of us are minors, so we should strengthen self-discipline when surfing the Internet and don't browse unhealthy websites! Network is a double-edged sword, and we should make use of its advantages and avoid its disadvantages.

Let the Internet serve our study and life, and make our study and life more exciting! ...

Talking about the advantages and disadvantages of middle school students surfing the Internet Speaking of the advantages and disadvantages of middle school students surfing the Internet, probably many people know this term. The appearance of the Internet is a sign of the progress of social times and the development of science and technology.

Surfing the Internet has become a popular trend in 2 1 century.

Among the population of China1300 million, the number of netizens has reached 1. 1 100 million.

With more and more people surfing the Internet.

There are more and more middle school students surfing the Internet, and the advantages and disadvantages of surfing the Internet have gradually become a concern: should middle school students surf the Internet? In my opinion, middle school students should surf the Internet, but enough is enough.

Speaking of surfing the Internet, you can not only chat, make friends, look up information and play games ..., but also get information conveniently and quickly, broaden your horizons, keep abreast of current events and news, and get all kinds of latest knowledge and information. You can chat with netizens without scruple, pour out your worries, reduce the burden of schoolwork and relieve stress; I can express my views and opinions on various issues on various BBS, and I feel very fulfilled; You can also improve the level of one of your hobbies; Now it has become a fashion to make your own home page. It's really great to upload your favorite pictures, open a discussion forum, post some posts and communicate with you.

No matter what the advantages and disadvantages are, there is only a thin line between them, which is often "a thousand miles away, a millionth difference", and the same is true for surfing the Internet.

Crossing the boundary of "benefit" is "disadvantage"

Nowadays, many parents don't want their children to surf the Internet often. Because I am afraid of my child's myopia.

I am afraid that my children are addicted to online games.

3. Afraid of being cheated.

Indeed, surfing the internet for a long time will cause visual fatigue, and the degree of myopia will gradually increase; Playing online games, light will lead to myopia, heavy will lead to academic neglect; In the network world, the credibility is not 100%, so you can't trust the network completely. Around us, victims of online deception abound.

Although surfing the Internet has many disadvantages, the advantages outweigh the disadvantages. We should treat surfing the Internet correctly, make efforts to make its disadvantages not appear around us, and make it a high-tech tool for us to get more useful information in our study and work.

Advantages and disadvantages of surfing the internet 500-word composition If the Paleolithic belongs to the fire of Zhoukoudian in Beijing; If we say that the first industrial revolution belonged to Watt and his steam engine; If the 20th century belongs to two world wars, what I want to say is that 2 1 century belongs to computers and the Internet.

Indeed, with the migration of the times and the development of science and technology, human society is entering the era of information networking.

Internet has opened a brand-new and colorful world for people, especially teenagers.

According to some expert surveys, teenagers spend a lot of time online.

30. 1% of the respondents have the habit of surfing the Internet frequently, and 82.5% of the respondents have their own computers with Internet access.

In the survey, when asked about the longest online time, 3 1.8% answered 9 hours and 25.9% answered 5-8 hours.

The survey also found that boys spend more time online than girls.

What do students do online? The survey shows that the proportion of chatting, playing games and downloading entertainment content is as high as 557%. Undoubtedly, the Internet is the most versatile and widely used media, which has built a broad platform for teenagers' autonomous learning, enabling students to acquire more information and knowledge, "stay at home" and "see the world". It provides students with a broad space to participate in social activities. "However, when China maintains our friendship, heaven is still our neighbor"; It enriches students' life and gets rid of the monotony of "two points and one line" reading life. Ah! The online world is so wonderful! However, it can't be ignored that the double-edged sword of the network has stabbed many teenagers who lack self-protection consciousness, and the openness and concealment of the network have instilled a lot of spiritual garbage into the simple heart.

Some credulous websites instigate, which leads to human tragedy; Some rashly met netizens and were injured innocently; Some people are addicted to black internet cafes, so it is difficult to neglect their studies. Others are keen on online games, and their moral concepts are vague and even confused by the law of the jungle and intrigue; Some were infected by online pornography such as gambling and pornography, and eventually went astray.

There are several classmates around me, intoxicated in the virtual space, starting to escape from reality, neglecting their studies and making themselves look haggard and trance.

Let parents sigh and teachers shake their heads.

Alas! It's sad to be addicted to the internet! Teenagers are in the golden age of their lives, beautiful nature beckons us, the peak of science needs us to climb, our parents with hard work expect us to grow up healthily, and the future of our motherland needs us to create brilliance ... There are too many things we should do! Can a small screen cover all our lives? "Water can carry a boat, and it can also overturn it.

Nowadays, teenagers' network security has become a hidden danger affecting national prosperity, social stability, school education and family harmony. I really hope that "electronic heroin" and "electronic network" can be caught in the net, and I also hope that all our young friends can have a clear understanding of the network and build a safe "firewall" in their minds!

The disadvantages of surfing the Internet Composition (300) Now, the Internet has become an indispensable part of people's lives.

So, is surfing the Internet good or bad for primary and secondary school students? To this end, our class held a seminar.

The discussion has begun.

Chen Tong said, "I don't think surfing the Internet is good because it wastes talents.

Some time ago, many people's computers were infected with the' panda burning incense' virus. According to news reports, the creator of this virus is a very smart person. If he can use his intelligence in the right place, he will certainly become the pillar of the country, so surfing the Internet is a waste of talents.

At this time, Huang said to the opposite opinion: "surfing the internet is also good!" You can check the information on the internet, so you don't have to turn over the books. How convenient! " Guo Xinyuan took to the stage and said, "I also think surfing the Internet is good.

You can buy online without going out. The Internet has provided convenience for people.

Wang Zihan said: "I think the disadvantages of surfing the Internet outweigh the advantages.

The information found online may not be all right. The quality of things bought online is not guaranteed, and they cannot be returned. There is no phone number and address.

Wang Xiaopeng said, "I don't think surfing the Internet is good either.

The internet will expose personal privacy.

Once a person looked up his name on Baidu, and the network actually exposed all his privacy! So I think surfing the Internet has disadvantages.

Students who support the internet badly say that surfing the internet will reduce their eyesight, while those who support the internet well say that chatting online is fast and convenient.

I think surfing the Internet has both advantages and disadvantages.

The advantage is that you can chat, talk and send emails online, which brings convenience to people.

The disadvantage is that some people use the internet to do things that are not good for society.

However, I think that as long as we can go to a healthy website, master the online time and use the network correctly, we can make the network a good helper for us.

On the advantages and disadvantages of middle school students surfing the internet (composition) 2 1 people in the century, the internet is no longer strange.

Let's learn a lot of network knowledge, and let's enjoy the knowledge ocean of travel.

The internet has provided us with great help.

Network makes us relax, let us talk about learning and make us happy, so we are as close as possible to communicate with our relatives.

We can also act as a "post office" through the e-mail network.

This not only saves paper, but also is so fast! At present, the research not only needs to remember book knowledge, but also needs a lot of extracurricular knowledge. Where can we find this extra-curricular knowledge?

It wants to ask for help from the computer. You can look up information on the Internet.

Surfing the Internet is very fast, and you can find it in a few minutes, which saves a lot of time than checkbooks, so you can save a lot of time, improve their learning efficiency and help their academic performance.

What information can we learn about the network in the first time? The Internet allows us to understand knowledge and world affairs together.

"A scholar knows what's going on in the world", so why not? But, classmate, do you know? Network is neutral, it is a double-edged sword, which is beneficial to human society and harmful to human beings.

Especially since 1995, the role of the network has increased, and its advantages and disadvantages can not be ignored.

Many students are addicted to the online virtual world and divorced from reality.

Different from the real social life, students are engaged in a virtual world. The Internet not only meets the information of students' various needs, but also gives them a wide range of international opportunities, allowing them to leave the imagination space without bearing the pressure and responsibility of real life.

These characteristics of virtual world make them prefer to indulge in fantasy environment rather than face real life all day.

They like to play online all night, which leads to physical decline, inattention and depression.

Carelessness delays studies and brings sadness to parents. Besides online games, there are other unhealthy information corrupting the minds of young students.

We also make the Internet a long-term visual loss.

Everything in the world is complementary, good and bad. Advantages and disadvantages are opposite. It depends on how we treat and deal with them. On the other hand, the disadvantages outweigh the advantages.

The network is mixed, good and bad.

Only with keen eyes and quick thinking, we can observe, learn and absorb the essence that is beneficial to us, eliminate the dross that is beneficial to us, make correct use of network resources and enrich our hearts.

We should be "civilized, civilized network", so help us in our life network.

Harm of surfing the Internet 2000 Taking care of children's health surfing the Internet 2 1 century is a competitive information age.

With the development of science and technology, computers have come to us, and the network has presented us with a beautiful and wonderful world.

When we relax, we need it to find information, draw pictures and play games online.

However, the network information on the computer is good and bad. We should use the Internet in a civilized way, surf the Internet in a civilized way and be civilized people.

From the mid-1940s to the mid-1950s, since the first electronic computer was invented by the US military, it has had an immeasurable impact on economic and social development.

The invention of network marks the coming of human information age.

Nowadays, surfing the Internet has become an increasingly frequent activity.

Internet is a media with unprecedented information content, variety and quantity. It breaks through the limitation of time and space, provides us with a brand-new way of study and life, and is of great help to our daily production and life.

Internet is the product of high technology, the crystallization of historical development, social progress and human wisdom. It is the information center with the largest capacity, the most complete content and the fastest transmission speed that human beings have so far.

The application of network is a double-edged sword, which has both advantages and disadvantages.

When we surf the Internet, we should give full play to the positive role of the network and avoid the harm of "network virus".

Internet provides us with convenient conditions for understanding current affairs, learning knowledge, communicating with people and entertaining.

Network communication includes not only the communication between friends in Oak Tree, but also all aspects of communication between strangers, such as online medical treatment, online family search, online consultation and so on.

Taking the Internet as a supplement to our life with a healthy attitude, we can enjoy many benefits of online communication, such as broadening our horizons, relaxing our mood, learning new knowledge and making new friends.

A person with ideals, goals and pursuits always arranges his life in an orderly way and will not waste time on things that are not beneficial to him.

In network communication, we should pay attention to browsing and looking for information related to learning, don't stay in front of irrelevant information, and don't waste energy on boring information. We should learn to "diet" and resist bad temptations on the Internet.

Be good at using network technology to solve problems in work, study and life; Help others solve some difficulties and do something beneficial to others and society.

Reflect your own life value in serving others and society.

Online Netease is affected by bad information such as online games. Long-term addiction to this can easily make students neglect their studies and even embark on the road of illegal crimes. Temptation and fraud also occur from time to time, which is not conducive to the healthy growth of teenagers.

For students who are addicted to the internet, we should explain its harm, persuade them to correct it, tell them to enhance their awareness and ability of self-protection and self-discipline according to law: inform parents, teachers or relevant departments in time; Help them leave bad networks and websites, actively advocate healthy surfing the Internet, and pay attention to browsing and learning related information.

Internet is not the whole of life. We should not be the captives of the network, but the masters of it.

While improving people's social labor quality, the network may also cause harm to some network users.

We should correctly understand the two sides of the network, foster strengths and avoid weaknesses, give full play to the positive role of network communication in life, and enjoy the fun brought by healthy communication.

In the face of the network, we must improve our safety awareness, don't disclose personal information easily, and don't agree to the requirements of netizens at will.

When you have a problem, try to find a familiar friend or teacher to help you solve it.

There are good and bad network information. As an online tourist, only by constantly improving their ability to distinguish and detect, and improving their ability to resist temptation, can they protect themselves.

Network can broaden our horizons and increase our knowledge.

We should make full use of the advantages of the network, strengthen our study, improve our quality and arrange our time scientifically and reasonably.

At the same time, there are still some factors that are not conducive to the healthy growth of teenagers. Middle school students should strengthen legal awareness and self-protection.

Self-discipline according to law, safeguard their legitimate rights and interests according to law, improve ideological and moral quality, cultivate elegant taste, abide by network conventions, do not browse unhealthy information, do not casually date netizens, consciously resist the temptation of bad problems, and surf the Internet in a civilized way.

With the continuous development of society, computer network has gradually become one of the main means for people to exchange information.

Its application field is getting wider and wider.

Therefore, we are required to start from consciousness and surf the Internet healthily.

The network world is rich and colorful, but there are also many unhealthy contents. In order to avoid being victimized, let's go hand in hand, abide by the law, "surf the Internet in a green and healthy way", cherish time, study hard, set up lofty ideals, and create a bright and clean blue sky together.

Network communication is as wonderful and helpless as real communication.

Familiar with the characteristics of the network and abide by the rules of surfing the internet, we can walk out of the wasteland and move towards a beautiful place!

Some parents, seeing that the Internet is the general trend, encourage their children to surf the Internet, but at the same time, they make a reasonable and clear online agreement with their children, including weekly online time and suitable websites to visit, and pay attention to timely urging and reminding their children to abide by the agreement.

In this way, parents and children will trust each other over time.

Facts show that this practice is successful for most families.

In addition, parents should instill in their children the idea that "the Internet works for me".

Let children understand that the online world and the real world are the same, and good, evil, beauty and ugliness coexist. The purpose of surfing the Internet is to absorb useful things on the Internet and serve your study and life. For unhealthy information encountered online, we should learn to refrain from in-depth contact, and finally let children consciously stay away from unhealthy things online and focus on learning knowledge and improving their ability.

From a distance, strive to cultivate and improve children's discrimination and self-control.

If the internet is already a part of children's lives, just as you care about the places where children go in and out in real life and the friends they associate with, you should know which websites your children go to, what they mainly do online, and what impact these websites may have on your children.

At the same time, pay attention to whether the child has abnormal changes. For this change, we should find out the reasons as soon as possible and come up with countermeasures.

If there is no computer at home, it is worthy of attention that children surf the Internet in Internet cafes.

Compared with surfing the internet at home, the special environment of internet cafes has a very unfavorable influence on children.

As parents, they should accompany their children to Internet cafes for a certain period of time.

You know, children are also thoughtful people, and they need to communicate with others and talk and vent in communication.

However, for various reasons, parents often do not take the initiative to create such opportunities for their children.

Some children desperately chat and play games online, which is also their psychological needs to some extent.

In response to this phenomenon, some experts remind parents not to let the internet become a spiritual haven for children.

Therefore, parents should communicate with their children to meet their psychological needs.

In the network age, parents should make full use of the characteristics of the network and create opportunities to communicate with their children.

If you are unfamiliar with network knowledge, you can ask your child to be your teacher, teach you how to surf the Internet, and let him introduce you to the websites he often goes to and what kind of games he likes to play.

With the child's consent, you can chat online, play games and watch the news with your child.

In this kind of communication with children, parents have achieved family harmony, and it is not difficult to communicate with each other.
