Computers are widely used, convenient and fast, and are well received by people.

But it also brings many disadvantages. Computers have many advantages.

For example, it can facilitate us to collect information.

When we want to do a special project, but lack information, as long as we surf the internet,

You can find a lot of information related to the project immediately, which is very convenient.

Students' language ability can be improved by computers. Now there is a "one a day" reading plan on the Internet. We only need five to ten minutes every day to read a high-quality article and finish after-school exercises.

If this goes on, our Chinese level will certainly be greatly improved over time. If students encounter something they don't understand in their homework, as soon as they get online, someone will solve the problem for us.

Computers can let us know a lot of extracurricular knowledge, and teachers let us look up information. If there are no books, we can use the computer, which is convenient and practical.

For example, shopping, booking air tickets, etc. can be ordered by computer now.

You can also make slides. Blog computers can also control production and transmit information. ..........................

First, the current situation of middle school students using computers: In today's society, the development of computers is advancing by leaps and bounds. Almost every family in the city has a computer, and we can't live without it. We are called the "new generation".

An indispensable part of study and life is the computer.

Through the investigation of students around us, our project team members believe that middle school students use computers mainly for the following purposes:

Used for learning (including drawing and writing), playing games (including listening to music and watching movies) and surfing the Internet.

The main uses of surfing the Internet are: online learning, searching for information, playing games (including listening to music and watching movies), chatting and making friends.

According to statistics, playing games accounts for the largest proportion, almost reaching more than 60%.

Second, the positive role of computers in the growth and progress of middle school students;

At present, it is very common for middle school students to use computers, but there are advantages and disadvantages. Computers are easily accepted by our middle school students. Its advantages,

Mainly as follows:

1 is an important way to master all kinds of knowledge quickly. Computers have become an important source of knowledge.

Most of the materials of the world's major libraries can be obtained through the network, which is not only quick to consult, but also saves a lot of extra expenses.

There are also news, materials, entertainment, literature and other information. Through the computer, we can see the latest, fastest and most authoritative news on the Internet, learn knowledge that books don't have, and learn a wider range of unknown information, so that more middle school students can get close to the forefront of science and technology faster and earlier, and let us love and admire science more.

2. Effective ways to receive education The current learning software is dazzling and much more interesting and flexible than books. Just like watching cartoons, it is easy to attract our attention.

A few thick encyclopedias of Britannica and a small CD can do it. There is also a new teaching method of "online school", where teachers teach you individually and "classmates" learn from each other in communication, completely getting rid of the shackles of face-to-face with teachers in class and being free from the constraints of time and place, which is of great help to our middle school students to play freely.

Computer is a useful tool to strengthen communication. Nowadays, almost all middle school students are only children. Except at school, I usually spend more time alone. I can surf the computer and chat in chat rooms or OICQ and other communication websites. In this virtual world,

Talking about their favorite topics, netizens, regardless of age and occupation, can express their feelings as long as they think they have the same interests. This is an excellent opportunity for us who are eager for friends, friendship and talk. We talked happily in the internet and got spiritual relaxation and relief.

Disadvantages of computer ..

1, computer radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, seriously induce cancer and accelerate the proliferation of cancer cells in human body.

2. The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia and decreased immune function of some women.

4. It has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on.

In fact, the quality of the computer is absolute, just as we have learned in physics, absolutely static objects do not exist. Similarly, the quality of computers is relative. If we are good at using it in a good way, then the home computer is obviously good for everyone. But on the contrary, if you are not good at using it, or even use it to do some bad things, then naturally, computers are not good for everyone. So I think the advantages and disadvantages of computers that we have repeatedly discussed are relative. Therefore, the computer is neutral, there is no difference between good and bad, it depends on how you use it.
