Advantages and Disadvantages of the Internet
Ten years ago, the Internet was practically unheard of by most people. Today, the Internet is one of the most powerful tools throughout the world. The Internet is a collection of various services and resources. According to Russ Brock, a director and consultant at the Center for Innovation and Inquiry, the Internet’s main components are E-mail and the World Wide Web. “There’s a lot more to the Internet than E-mail, search engines, celerity web sites, up-to-the-second sports scores, and chat rooms full of risqué discussions. The Net also ranks as one of today’s best business tools - if it’s used adroitly”. Almost all households contain the Internet; however, before people connect to the Internet, they need to be aware of its disadvantages and advantages.

Many fear the Internet because of its disadvantages. They claim to not use the Internet because they are afraid of the possible consequences or are simply not interested. People who have yet connected to the Internet claim they are not missing anything. Today’s technological society must realize, it is up to them to protect themselves on the Internet “Half of U.S. adults, or 94 million Americans, aren’t online”.
Children using the Internet has become a big concern. Most parents do not realize the dangers involved when their children log onto the Internet. When children are online, they can easily be lured into something dangerous. When children talk to others online, they do not realize they could actually be talking to a harmful person. As a result, there have been many cases where children have been convinced to meet people they have talked with online. In fact, “stories seem to come out every week: a child or teenager lured into something foolish, dangerous, or even deadly on line” . Cathy Cleaver of the Family Research Council claims that it is against the law for a molester to even attempt to find children online . In addition, children may also receive pornography online by mistake; therefore, causing concern among parents everywhere. Whether surfing the Web, reading newsgroups, or using email, children can be exposed to extremely inappropriate material. Pornographic sites tend to make sure they are the first sites to be listed in any search area; thus, children come across such sites easily. A man from Pearl, Mississippi was arrested in 1996 for downloading pornographic images of children from the Internet. He was charged with 290 counts of child pornography . Some critics say that parents are responsible for their own children on the Internet because there are available services to protect children. To keep children safe, parents and teachers must be aware of the dangers. They must actively guide and guard their children online. Parents should talk to their children about what is online and what might happen online, claims Howard Rheingold, writer of The Virtual Community . There are a number of tools available today that may help keep the Internet environment safer for children. Some companies, such as America Online, try to monitor everything that is said and done on their online service; however, because thousands of chat rooms are available, it is simply impossible for everything to be monitored, claims Tricia Primrose, worker for America Online . In other words, children want to explore things; however, there are people on the Internet that are just too persuasive.

As we all know, more and more students get on-line. Just as a coin has two sides. Students' surfing the internet has both its advantages and disadvantages.
On one hand, students can learn how to use the modern machine---computers by surfing the Internet. By using the computers and surfing the Internet, they can learn more knowledge and information. Most students also find that playing computer games makes them more intelligent. All of these are certainly of great benefit to the students.
On the other hand,some students spend too much time in playing games , which is harmful to those students' health and growth. And there are some students who use so much time to be on-line that they fall behind others in studies.
In my opinion, students shouldn't surf the Internet at school. When spending summer or winter holidays, they can use some time to be on-line.

Speak of the Internet, probably a lot of people know this noun, the emergence of the network society is the progress of The Times, the development of science and technology of the sign. The Internet has become a popular trend in the 21 st century. Of the 1.3 billion people in China, Internet users have to 1. 100 million people. As the number of the Internet is growing. Middle school students surf the Internet more and more, the advantages and disadvantages of the Internet also gradually become the people's concern as to what the middle school students should not to the Internet?

My standpoint middle school students should get to the Internet, but should be enough is enough. Say to the Internet, Internet not only can talk, friends, check information, play games... , can also convenient and rapid access to information, can open field of vision, and know the news, get all sorts of new knowledge and information; Can't scruple with net friend chat, pour out the concern, reduce schoolwork burden, ease the pressure; Can in each BBS posted on a variety of issues of his views and opinions, feel very has the sense of achievement; Still can improve a hobby level; Now to make his own home page has become fashion, put their favorite picture preach up, open a discussion forum, hair some stick son, and we exchange, own the moderator is fantastic.

Whatever benefits and disadvantages, there is a thin line between, often is "a miss is as good as a mile," the Internet is also like this. Across the "benefit" of boundary is "harm".

Many of today's parents don't want their children often surf the Internet, 1, because he's afraid of their own children myopia. 2, afraid of their own children indulge in online games. 3, afraid of fraud. Indeed, long time of Internet can cause visual fatigue, and, myopic degree will gradually increase; And playing online games, light can lead to myopia, heavy also lead to academic desolation; But in the virtual world, credibility is not 100%, we can't fully believe that network, at our side, network victims of fraud also can be found everywhere.

Although the Internet the disadvantages of many, but still outweigh the costs, we should be the right to get to the Internet, strive for the disadvantages of it in hand appear, let it be us study, work to get more useful information on the high-tech tools.
