Hello, teachers and students Now with the development of science and technology, human civilization has taken a big step forward, from the previous carriage to the car, from the previous oil lamp to the electric light. ...

Now many people are wondering whether the development of science and technology is beneficial or harmful. Without a doubt, of course it is Lida! What is the explanation? No need to explain! China's 8,000-year history of civilization is irrefutable evidence. History has been changing and technology has been developing. Humans have learned to cook food with fire from primitive life, from dependence on nature to reproduction, from unarmed to metallurgical smelting. Isn't this all progress? Isn't this all development? If the disadvantages outweigh the advantages, then why do human beings choose progress in unison? Only progress can make tomorrow better!

It is sad for a person not to make progress, a country is declining without progress, and a world is dark without progress. Only by continuous progress can human life be sublimated. Man is small and fragile. He has no huge body, no strength like an ox, and no hard shell like a turtle. However, God has given mankind a clever brain and a pair of hard-working hands. Instead of enjoying success, human beings have chosen to make continuous progress and stand at the top of today's food chain. Because of Faraday, our life is full of all kinds of electrical appliances; Because of Darwin and Mendel, we can know ourselves better and know ourselves; Because of Bian Que, because of Hua Tuo and because of Li Shizhen, our lives can be guaranteed.

Didn't they buy everything around us? Life is so comfortable, life is so pleasant and life is so wonderful. Our average life expectancy is 30 years higher than that in ancient times, and we don't even have to go out to visit relatives and friends. Isn't this all the benefits of scientific development?

Therefore, science and technology change history, and we don't need to question whether the development of science and technology is beneficial or harmful, because it is beneficial! You said that the development of science and technology has brought air pollution, you said that the development of science and technology has produced white garbage, and you said that the development of science and technology has caused the warming of the temperature ... Everything can't be perfect, and the darker the shadow behind the brighter place, but on this basis, you can draw the conclusion that the disadvantages of science and technology development outweigh the advantages? Different times lead to different problems. Except air pollution, all provinces and cities have put forward prevention plans. White garbage, unified treatment; Automobile exhaust causes the temperature to warm, and scientists have also developed solar-powered cars. Look at now, solar water heaters, solar air conditioners, solar cells ... environmental protection and energy-saving solar energy are gradually entering thousands of households. Isn't this the development of science and technology?

If you say that the development of science and technology does more harm than good, can you come to class without a car, gel pen, ballpoint pen and pen within a week? Can you stop watching TV, listening to the radio, reading newspapers, reading books and surfing the Internet for a week? Can the developed hybrid rice not be eaten for a week? No spaghetti? Don't drink? No, you can't, you can't and can't, because technology is closely related to you and inseparable from you!

In ancient times, many people were seriously ill, and doctors could do nothing but watch patients die painfully. But now, through the development of science and technology, most intractable diseases have been successfully cured, and people don't have to worry about getting sick. In ancient times, communication was very inconvenient, and even people died at home, and the wanderers in their hometown had to wait for more than a month to know; But now, communication has become very fast and convenient. Mobile phone, TV, newspaper, e-mail, etc. , has become a new way to close the distance between people. The above example is just the tip of the iceberg of the case that scientific and technological development benefits mankind. The rapid development of science and technology is unimaginable to ancient people. Why do TV and newspapers talk about promoting the development of science and technology almost every day, because how is the dream of flying for thousands of years round? It is the development of science and technology; What makes communication convenient? It is the development of science and technology; Why can seriously ill people live a happy life again? It is the development of science and technology! If the development of science and technology is wrong, then why do inventors and scientists such as Galileo, Newton, Edison, Madame Curie and Einstein dedicate their precious lives to science? Why spend so much precious time on the "wrong" cause? Have they no judgment? Who thinks their death is worthless, and who thinks their contribution to science is meaningless?
