Of course, it is great that human beings can enter capitalist society, slave society and feudal society from primitive society. These changes are the result of the development of science and technology. Science and technology have developed productive forces, making the development of human society constantly adopt the way of human existence. Compared with 6,543,800 years ago, it will not change much. Compared with before 2000, there will not be much change before 3000; Compared with 500 years ago, there will not be much change 600 years ago. However, today's people are not the people they used to be. Even now, compared with 100 years ago, they are completely different. What has promoted the development of human history? What made mankind start a new way of life?
I said, this is technology. It is the development of science and technology that promotes the progress of mankind. It is the development of science and technology that gives mankind this brand-new and beautiful life. Throughout the ages, which dynasty and generation did not attach importance to the development of science and technology? Looking back, the four great inventions are unique; Look at the astronomical calendar and marvel; Look at Zhaozhou Arch Bridge, which is beautifully designed; A glimpse of the oriental masterpiece compendium of materia medica: look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue and white porcelain is very famous overseas. Scientific and technological development is the road to a strong country and the first driving force for the progress of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can you eat hybrid 2? How can I put on cotton-padded jacket and live in a tall building?
Q: Is the development of science and technology 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 learn to use or cook food from primitive life, from relying on nature to thriving, from unarmed to metallurgical smelting. This is not progress, this is not 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.
Let's compare today's life with that of 10 million years ago, and we are supreme; Comparing today with thousands of years ago, we are condescending; Comparing today with hundreds of years ago, we are happy and comfortable; Comparing today with tomorrow, the future is bright. For thousands of years, it has changed from a carriage to a car, train and plane; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat and mouse know everything about the world.
We are happy, we are lucky, and we have caught up with an era of rapid development of science and technology, an era full of high technology. This is not only because our ancestors chose development and progress in evolution, but also includes the unremitting efforts and hard study of all people. How many hard-working scientists have bought it with their wisdom and even their lives today.
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! Rita! Rita! 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?
Although there are disadvantages, it is irrelevant compared with the scientific and technological development concept of benefiting mankind and protecting home. As long as there are drawbacks, scientists will try to solve them. We can't stop eating because of choking, and the pace of scientific and technological development will not stop for a moment. There is nothing wrong with the development of science and technology, that is, to benefit greatly. This is the only answer to this argument! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth. If you say that the development of science and technology is harmful, science and technology change history and knowledge changes destiny. We have entered the 2 1 century, an era full of high technology. Science has changed our lives, and science has changed our destiny. "Knowledge is power". Why do we, the people of China, a vast country with a population of 65.438+0.3 billion, stand tall in front of the world? Because our technology is constantly developing! Our technology is constantly improving!
The advantages of scientific and technological development outweigh the disadvantages, which is an eternal theme! Progress, which is the great contribution of science and technology to mankind.
Need to refute:
Against: Environmental pollution is the most direct and obvious disadvantage.
If you can't say that, take plastic bags for example! It is not that our technology is too advanced, but that our technology is not advanced. If we can, we will not use plastic bags, but invent low-cost and environmentally-friendly shopping bags. Because of this, we should develop environmental protection technology. Without science and technology, how can we control the annual flood, or can we learn from Dayu and dig more canals? Besides, Dayu also said, "Man struggles upwards and water flows downwards." We should keep pace with the times, shouldn't we? Besides, is there no relationship between environmental pollution and population expansion? In fact, environmental pollution is caused by human use and technology, but now it is blamed on technology. Isn't it a little embarrassing? Grandpa Deng Xiaoping once said, "Science and technology are the primary productive forces." What do you think of this?
On the contrary: extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.
In that case, the kitchen knife will hurt people. We don't need a kitchen knife Let's learn karate and cut vegetables! The indiscriminate killing of human beings has nothing to do with technology, but the chief culprit is human greed. After all, guns don't kill animals by themselves. You can't blame everything on technology. Just want to compare the carrier to a horse, people are coachmen, and the carriage behind them is loaded with goods, that is, technology. If the horse goes in the wrong direction, that is, people develop technology in a bad direction, will the coachman whip the horse or play with technology? This is a simple example, but it shows that the quality of the environment has nothing to do with technology, but with where human beings use technology. It is a double-edged sword, on the one hand, it can crush ignorance and backwardness, on the other hand, it may bring endless disasters to mankind. It is good for you to do good, but if you do bad, the result will be different. In addition, if there is no hybrid rice, everyone will eat bark for half a year. Without penicillin, everyone will get tuberculosis. Will the development of science and technology destroy the environment?
Counterparty: What about the panda?
Darwin once said, "Survival of the fittest is the law of nature." However, the reproductive ability of pandas is weaker than that of other animals, and their picky eaters and habit of living alone make them endangered. Look at cockroaches. Even if the atomic bomb goes off, aren't the cockroaches there still "running well-off"? Besides, science can also help pandas, heal their wounds and deliver babies. How nice!
Against: Personal safety is increasingly insecure. Now tens of thousands of crimes occur every day on average, and their criminal methods are related to the new technology in Otawa. Especially gun-related crimes, ordinary people can't prevent them. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction.
Your point of view is really "one leaf can't see Mount Tai"! In the past, due to the corruption and incompetence of the Qing government, we closed our doors to the outside world. China lags far behind the west in science, technology and military development. Other people's guns are loud and large in caliber, and warships are strong and explosion-resistant. While others are eyeing up to invade us, we in China are still holding spears and shields. As a result, the Boxer Rebellion lost to Eight-Nation Alliance. This is a bloody lesson of history. Although we don't respect war, as a world power, we should have excellent military science and technology and lay a solid foundation for national defense. Isn't it?
On the contrary: the physical quality of human beings is not as good as before. With the development of science and technology, the appearance of vehicles such as cars, trains and planes has greatly changed the daily life of human beings. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. It is impossible for Xiang Yu to "pull out the mountains and rivers" in today's society. If this situation continues to develop, it may make people's limbs atrophy and make people appear.
Well, to tell you the truth, even if you invite ancient Xiang Yu, he is unlikely to enter the top ten weightlifting in the Olympic Games. Because the Olympic Games is also a technical contest between countries. When the weight exceeds the human limit, we have to rely on technology to help. During training, the coach will show the athletes videos, analyze with him which muscle to use in lifting, pulling, writhing and jerk, and then strengthen muscle training. This all requires technology. Besides, technology brings convenience to mankind. Four students across the street, I ask you, which one of you has been walking home with two legs after school? Don't you also use transportation? In fact, Xiang Yu's poems are only used to express ambitions, and there are exaggerated techniques. Do you really believe that the neck handle was pulled up the hill?
On the contrary, all kinds of new germs appear constantly, and the lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can not keep up with the mutation speed of virus. Maybe one day mankind will perish because of a great plague.
That's because human technology can't keep up. If we can keep up, we can develop more drugs to kill bacteria. Please don't focus on the disadvantages of technology. Everyone living on the earth enjoys the fruits of science and technology all the time. Including four students from the opposing side, I believe you have to refute that our materials are all from the internet or newspapers, which is also technology. On your own conscience, do you really think that technology should not appear on the earth?
Summary:
May 2008, 12, 14:28, I believe everyone is familiar with this time. At that time, an earthquake measuring 8.0 on the Richter scale occurred in Wenchuan County, Sichuan Province. Everyone knows the story behind it. But let's think about it, what sent the liberation officers and soldiers to the disaster area by water? What airdropped relief supplies to the disaster area? When did you first get through to Wenchuan? What helps people saw through steel bars and dig out the injured? What helped the doctor pull the rescued wounded back from the dying line? -assault boats, helicopters, excavators, chain saws and medical equipment. This is the power of technology! We should continue to develop science and technology and build houses that can resist earthquakes, so that more people can survive. This natural disaster has strengthened our view that the development of science and technology will benefit the future!
