As the greatest invention in the 20th century, computers have gradually become an indispensable part of people's lives. I believe that in the near future, there will be a phenomenon that everyone has a mobile phone, and its popularity can be comparable to that of mobile phones, and its application direction is more extensive. The work of the post office has become easier, because people no longer contact people by writing letters, but send emails, chat with QQ or use MSN to go directly to the computer; The library has also become empty. If you want to find information and learn, just tap on the keyboard and press the "Enter" key, and you're done. Shopping malls are gradually being replaced, and online shopping has become a trend. You can buy anything without leaving home, and people's lives have reached unprecedented convenience.
On the other hand, while computers bring convenience to people, they also bring many new problems to people's lives. More and more people, especially teenagers, are addicted to the virtual world of the Internet. They choose to passively escape the rules and regulations in real life. In the illusory world, they do whatever they want and do whatever they want. The resulting pornography, violence, illegality and crime have become important problems that cannot be ignored and difficult to solve in the process of social education and even cultural development.
An important problem also caused by computers is computer hackers and computer viruses. Because of convenience, many enterprises, banks and state institutions store internal data in computers, but this gives some people the opportunity to steal data and even make huge profits from it. These people are the so-called computer hackers, as well as computer viruses, which have seriously affected people's use of computers and networks. Recently, I often hear teachers complain about computer viruses in class, and I often witness problems with teachers' laptops due to viruses in class.
In fact, everything has its two sides, computers are no exception, and technology is no exception. As the primary productive force, science and technology is of decisive significance to the present and future development of a country and a nation. 2 1 century, scientific and technological progress is changing with each passing day, which is increasingly becoming the decisive factor of economic and social development. The growth of national wealth and the improvement of human life depend more and more on the accumulation and innovation of knowledge, and the competition of science and technology has become the focus of international comprehensive national strength competition.
Scientific and technological innovation, embodied in life, is a leap in the quality of human life. The invention, creation and use of automobiles, trains and airplanes stopped the ancient phenomenon of taking exams in Beijing for half a year. Now I want to go to Beijing, which takes less than a day by car and a few hours by plane. With the development of space technology and the launch of China Shenzhou manned spacecraft, the myths and legends of "flying to the sky" and "flying to the moon" are presented to people in real life. With the application of fresh-keeping technology and the invention of refrigerator, we can keep food for a longer time, and we can eat cold ice cream, ice cream, cold beer and drinks in summer. When a place is dry and hot, artificial rainfall can be used to reduce showers. Computers can be as small as notebooks and can be carried around. Besides making phone calls, mobile phones can also listen to songs, take photos, read e-books, watch movies and surf the Internet. In short, in our daily life, we can feel the influence of scientific and technological progress on us anytime and anywhere. Everything is inseparable from science and technology, which has been integrated with human life.
However, when technology paints a magnificent blueprint for our life, it also leaves many stains and failures. Improper application of science and technology will also have certain negative consequences. In the process of developing modern industry, the violation of natural laws, destruction of ecological balance, environmental pollution, soil hardening caused by the abuse of pesticides and fertilizers in agricultural production, and the negative consequences brought by the development and utilization of atomic energy have all done harm to human survival and development to varying degrees. Hegemonists in the world use modern science and technology to develop weapons and invade other countries, causing a lot of loss of life and property. The two world wars in history are the best examples. The Japanese war of aggression against China left a huge, heavy and permanent pain for China, which we can't erase from our memory. Japan is also culpable of punishment. The United States dropped two atomic bombs, which still has a great influence.
Therefore, science and technology in today's world also have duality. Science and technology is a double-edged sword. If used well, it will make a positive contribution. If it is not used well, it will have adverse consequences and suffer a big loss. How to use and develop science and technology with scientific outlook on nature and development has become a major problem to be solved urgently in today's world.
