With the rapid development of the times, computers have entered thousands of households. However, this seemingly simple computer can make a person become a pillar of talent, or go to uncontrollable fields.
Computers have a wide range of uses, rich in online content, all kinds of knowledge, all kinds of information. For teenagers, if it can be used in the right way, it will be of great help to their study. For example, if you play some games that are good for your body and mind, you can not only relax your mood, but also improve your computer operation ability. You can kill two birds with one stone. Why not? It is fast and convenient for searching information. As long as you have something you don't understand, or feel that the information on hand is limited, you can consult Mr. computer. If there is no computer at home, and you have strong self-control, even to the Internet bar, you can find the information you want. In addition, we can read news and listen to music on the Internet, discuss problems with friends from all over the world, and listen to teachers at home
Computers have both advantages and disadvantages. If you can't use them correctly, you will have endless troubles. This is a real case: there is a minor in Hebei who often plays a kind of violent game like stabbing people with a knife in an Internet bar. Because of the low technology, he has been killed all the time. A person who plays games with him always sneers at him. Once, the person who has fully integrated into the game picked up the fruit knife, stabbed the person beside him, and killed him. When the police came, the man woke up and knew that he had killed someone. What a painful lesson! This case constantly warns us not to browse the bad information on the Internet and not to play violent games.
Students, the computer, the network is a powerful double-edged sword, must use correctly. Remember! Remember! The 21st century is a century of high-speed development of information, people from all walks of life are inseparable from the computer to bring us information, its development by leaps and bounds. It's like a huge treasure house of gold, containing countless treasures. Make people's life more interesting and colorful!
Someone has said such a sentence: "the computer, like a book, brings us knowledge and fun." Yes, in our daily life, computers can help us solve our problems. When you are depressed, you must feel comfortable listening to music and watching movies on the Internet. Computer is also a happy messenger. Booking air tickets in advance will make you have a good time. Computer shopping has gradually become a fashion. We students no longer have to squeeze the bus. Computer is also a multi-functional telephone, it can "thousands of miles sound", even if one in the end of the world, one in the Cape, chatting through the Internet, also like close at hand, really "the end of the world if neighboring!"
Known as the "new generation", an indispensable part of our study and life is the computer. It is our reliable friend. When we encounter problems that we don't understand, we can check the information on the Internet. Look, the problem is solved in less than a minute. In the spare time, you can turn over the library, it not only can check quickly, but also save a lot of extra expenses. Let us understand the recent national events, dance with nature, but also enrich our after-school knowledge.
You must have never heard that computers can save people's lives! Calling for help on the computer can save a young person's life. Telemedicine enables doctors to quickly reach the patient's location for rescue. So the computer is also the most convenient life signal. It makes people's life bloom again! composition
But the computer is also a very disguised devil, some primary school students often rely on the Internet, do not use their brains to think about problems, encounter do not understand the Internet search, and even copy the composition on the Internet, thus gradually towards the road of crime. Some adults are "intoxicated" in the game every day. They don't have a good sleep and have a great influence on their work. Some women shop online all day, and they have no understanding of the society, and there is less contact between people. So the network has advantages and disadvantages, we should correctly treat the network, do not indulge in the network, be a useful person to the society.
I want to appeal to the world: be alert to electronic killers, use computers correctly, don't let yourself be superstitious by the Internet, don't fall into the terrible black hole of the Internet, hold your sails well and let it sail to the other side of success! More than 200 years ago, the invention of the steam engine brought mankind into the industrialized society; more than 100 years ago, the emergence of electric lights presented mankind with a colorful electrified world; 60 years ago, the emergence of computers brought mankind into the orbit of rapid development, and the earth became a village. The computer is gradually becoming the master of human production and life.
The use of computers has greatly improved production efficiency. From Spaceship Launch to nanotechnology research, from nuclear bomb to assembly line production, all aspects of human production have been improved by the use of computers. A computer the size of several basketball courts in the Alamos National Laboratory of the United States can be used to simulate nuclear tests. It can calculate tens of billions of times a second, and can finish the work that human beings can never finish in a few days. Even in the ordinary industry, computers play an important role. For example, in the field of education, a teacher wants to count the scores of a certain exam in a grade, calculate the average score, use the computer, just a few seconds, if you use the manual calculation, it will take a few hours.
Computers and the Internet based on computers promote rapid economic growth. The Internet makes it more convenient for people to obtain information, thus speeding up the investment, production, sales and other links, which is conducive to the rapid development of economy. Former U.S. President Bill Clinton put forward the plan of "information superhighway" in 1992, which aims to improve the speed of information transmission on the Internet, making the U.S. economy grow steadily and rapidly for several years.
Computers are also increasingly influencing the way of human life. The emergence of the Internet eliminates the regional gap, so that people from all over the world can get together to talk, stay at home, enjoy the world. The fantastic idea of cleaning a room thousands of miles away has also been realized with the help of computers. composition
Of course, computers have many advantages as well as many hidden dangers. So some people think that the disadvantages of the computer outweigh the advantages, hindering the development of society. Of course, this view is wrong. Computers, especially the Internet, have been around for a short time, and it will take a long time to improve and develop. Moreover, it is impossible for every thing to have only worries and no shortcomings. Nuclear energy can give us a huge amount of energy, and at the same time, it has a nuclear shadow over us. Cloning is a breakthrough in human science, but it is against human ethics.
Computers and the Internet are playing an increasingly important role. What should we do? A survey shows that there are only three million Internet users in Russia, a great country, which gives us a deeper understanding of the reasons for its decline. Facts have proved that the lack of popularity of computers and the Internet leads to the blocking of information, the blocking of information leads to the backwardness of production, and the backwardness of production leads to the backwardness of national strength. If China, whose economy has just taken off, does not want to fall behind again, it must pay attention to the popularization of computers and the Internet. Fortunately, China already has its own computer companies and network companies, such as Lenovo, founder, Sina and Sohu, although it is far away from self-development. composition
The whirlwind of computer and Internet is blowing. Are you ready? Is the development of science and technology a big disadvantage or a big advantage? I think the development of science and technology has both disadvantages and advantages. Computers can reduce a lot of people's burden. It can help us save a lot of time. In the past, it took us several hours to write materials and reports, but now we get twice the result with computers. Now whether it is over 60 years old, or 6, 7-year-old children have begun to learn computer. The content of this page is pushed by "Sihai reading network". While it brings us benefits, it also brings us disadvantages. Some people are searching for life and death for computers. People say that the reason for this is games and online chatting. Some people indulge in computer games and can't extricate themselves, some Xie commit suicide for him, some quarrel with his family, some even kill their relatives because of computer games. How terrible, but it's true, but most people think it's still chatting on the Internet. But there are also people who fight against the injustice. People invented computers to provide convenience for people, and then invented the Internet, and then the chat room. At the beginning, it was to let friends from all over the world know, but also for people to relax. Later, some people gave up their studies because of chatting on the Internet, and some people can be said to be possessed. In order to get money to the Internet bar, they ask their parents for it. In order to make them turn back and refuse to give it, they can get the kicks and punches of their children. Some children in their 10s killed their parents themselves because their parents were willing to give money. It's all in black and white. Some people made an appointment to have a party because they could talk with netizens, but after meeting, some were killed Ransacking finance, some of them being abducted and sold. But not everyone will end up in the second place. Some people have the ability of self-control and know what is important, so they only take chatting online as a pastime and can find some netizens to vent their anger. Therefore, everything in the world has two sides, both good and bad. Both good and bad are up to the user. The same is true of the development of science and technology, and its advantages and disadvantages are determined by the users. The advantages and disadvantages of the development of science and technology, the society is in constant progress, science and technology is in constant innovation, the development of science and technology does bring a lot of benefits to people, but I think the disadvantages of the development of science and technology are greater than the advantages.
Of course, there is also the development of science and technology. Of course, the benefits brought by the development of science and technology to mankind are obvious to all. In ancient times, in the feudal society without science and technology, in the ancient times hundreds of thousands of years ago, people even lived a life of drinking blood and taking trees as nests. At that time, there were no computers, no televisions, no high-speed vehicles, and no essential electronic supplies. Without the development of science and technology, ancient people would gradually degenerate, and human beings would not have evolved into the only higher animal today. With the development of science and technology, our life has undergone rapid changes, bringing convenience to our life: we can go out by car, by boat, or even by plane. We don't have to walk on foot like ancient people. It takes several years to get to another place. With lights at night, we no longer need to live the life of "working at sunrise and resting at sunrise". We want to know more about different places News can turn on TV and log on to the Internet. In ancient times without science and technology, what happened in one area might not be known to people in another area until a few years later
However, there is no perfect thing in the world, and the development of science and technology will bring both advantages and disadvantages. Let's take global warming as an example: automobiles are becoming more and more popular, and the harmful gases (automobile exhaust) emitted from the burning of thousands of automobiles will destroy the earth's ozone layer, directly leading to global warming, melting of Antarctic glaciers, and extinction of more than ten kinds of animals. In the future, the rising sea water will threaten Shanghai and other coastal cities, making them submerged!
