Advantages of computer: \x0d but it also brings many disadvantages. Computers have many advantages, for example, it is convenient for us to collect data. \x0d When we want to do a special project, but lack of information, we can find a lot of information related to the special project immediately by surfing the Internet, which is very convenient. \x0d Students' language level can be improved by computers. At present, there is a reading plan of "one article a day" on the Internet. We only need five to ten minutes every day to read a high-quality article and finish after-school exercises. \x0d If this continues, our Chinese level will definitely be greatly improved. If students encounter something they don't understand in their homework, as long as they surf the Internet, someone will solve the problem for us. \x0d Computers can let us know a lot of extra-curricular knowledge. The teacher asked us to search for information. If we don't have books, it is convenient and practical to use computers. \x0d Now, we can use the computer to order things, book air tickets and so on. \x0d 1。 Analysis of the current situation of middle school students using computers: In today's society, computers are developing by leaps and bounds, and almost every family in the city has computers. Our life is inseparable from computers, and we are called the "new generation". X0d is an indispensable part of our study and life. \x0d According to the survey of our classmates, our team members think that middle school students use computers mainly for the following purposes: \x0d is used for learning (including drawing and writing), playing games (including listening to music and watching movies) and surfing the Internet. \x0d and surfing the Internet mainly have the following purposes: online learning, searching for information and playing games (including listening to music and watching movies) x0d According to statistics, the time spent playing games accounts for the largest proportion, almost reaching more than 60%. \x0d Second, the positive role of computers in the growth and progress of middle school students: \x0d At present, it is very common for middle school students to use computers, but there are advantages and disadvantages. Computer is easily accepted by our middle school students, and its advantages are as follows: \ X0d 1 is an important way to quickly master all kinds of knowledge. Computers have become an important source of knowledge. \x0d Most of the information of the world's major libraries can be obtained through computers, which not only saves a lot of extra expenses, but also saves a lot of news, materials, entertainment, literature and other information. We can see the latest, fastest and most authoritative news on the internet through computers. We can learn knowledge that books don't have, learn a wider range of unknown information, let more middle school students get close to the forefront of science and technology faster and earlier, and let us love and admire science more. \x0d2。 An effective way to receive education. Nowadays, learning software is dazzling, much more interesting and flexible than books. Just like watching cartoons, it is easy to attract our attention. It can be done with a Zhang Xiaoguang plate. There is also a new teaching method called "online school", where teachers teach you individually and "classmates" learn from each other in communication. There is no constraint of face-to-face with teachers in class, and it is not limited by time and place, which is of great help to our middle school students to play freely. \x0d3。 Computers are a useful tool to strengthen communication. Almost all middle school students are now. Except at school, we usually spend more time alone, but we can surf the computer and chat in chat rooms or other communication websites such as OICQ. In this virtual world, users can express their feelings regardless of age \x0d occupation, as long as they think their interests are the same.

Computer radiation pollution will affect the human body's circulatory system, immunity, reproduction and metabolic functions, which will seriously induce cancer and accelerate the proliferation of cancer cells in the human body. \x0d2。 The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder in some women, bradycardia, decreased cardiac output, irregular sinus heart rate and leukopenia. X0d4。 It has a bad influence on people's visual system. Because the eyes belong to the sensitive organs of human body to electromagnetic radiation, too high electromagnetic radiation pollution will also have an impact on the visual system. Mainly manifested as decreased vision, causing cataracts and so on. \x0d In fact, the quality of a computer is absolute. 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 them, we can use them in good places. Then, home computers are obviously good for everyone. On the contrary, if you are not good at using it, or even use it to do some bad things, then naturally, computers are bad for everyone. Therefore, I think the advantages and disadvantages of computers that we have discussed again and again are relative. So the computer is neutral, there is no difference between good and bad, depending on how you use it.
