Compared with 654.38+ million years ago, the way of human existence 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 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 news, 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, no and no, because technology is closely related to you and inseparable from you! Now if you write to the chairman and suggest stopping all scientific research activities, will everyone send you flowers or the board of directors shoot you exclusively?
It is true that technology has changed history. Without the development of science and technology, our life is unimaginable. Our days are dark. It was the development of science and technology that saved us, and it was science that saved us from the age of hydrothermal. We should respect him with awe. How can we say that the development of science and technology is full of drawbacks?
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!
Advantages and disadvantages of scientific and technological development
Conclusion: Although the development of science and technology is important, it cannot be developed on the premise of reasonable and normal use. Development must first purify the mind. Only when no one's mind and soul are developed and improved can the development of high technology be beneficial to human development and the harmony of nature forever!
Disadvantages: As mentioned above, everyone's eyes are higher and farther, which makes us only see higher things in the distance, to explore and pursue, and ignore what we should do at present. Just like some monarchs in history who want to live forever, they use drugs to treat diseases, and as a result, they blindly invest to realize some impossible things. As a result, they hurt others and themselves, and the macro scene that people see in movies now appears.
The development of science and technology not only brings convenience to people, but also brings disaster. Leon: We can go where we want. People are constantly exploring that in the future, the Sun Center Association may be overthrown. With the development of science and technology, no one can enjoy what those historical figures can't enjoy. Every newcomer has a different understanding of the world, and our eyes are farther away!

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!
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!
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, people's lives are getting better and better. Use the telephone to speed up communication, use cars and motorcycles to speed up the pace of life, and use electric cookers and gas to cook delicious meals. ...
Television is indispensable in life. We can watch the news and learn about things at home and abroad; You can watch cartoons and relax; You can also not go to the scene to watch programs and performances; For example, when the Olympic mascots are announced, you can watch the broadcast at home.
Computers are more and more widely used in all walks of life. We sent a letter to Brazil in Haining, and it only took a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world online. You can watch news, movies and listen to music online. You can listen to the teacher in class, find information, shop at home, have medical treatment and give first aid. ...
It can be said that technology is closely related to us. With this advanced technology, our life is faster, more convenient and more colorful.
We can go where we want to go, people are constantly exploring, and in the future, the connection with the sun center may be overthrown. With the development of science and technology, no one can enjoy what those historical figures can't enjoy. Every newcomer has a different understanding of the world, and our eyes are farther away!
1. Necessity. This is an era of knowledge economy, information is expanding and exploding at an unprecedented speed, and the future world is the world of network. If China wants to keep pace with the times in this information world, as the main force in the 2 1 century, it must be able to adapt to this high-tech society more quickly, have the ability to obtain effective scientific information from the outside world quickly and timely, and have the ability to disseminate scientific information, which is scientific quality. And the Internet has just adapted to this requirement. Didn't Grandpa Deng Xiaoping say, "Computers should start with dolls"?
2. practicality. The resources of the online world are enjoyed, just like a cornucopia, an inexhaustible "golden mountain of wealth". Whoever works hard on this golden mountain will gain something. We can find learning materials from them at the fastest speed, learn more extracurricular knowledge, use the knowledge in class flexibly, promote the development of thinking and cultivate the creativity of primary school students. Surfing the internet can also transcend the time and space and economic restrictions and receive online education from prestigious schools. If you have any questions, you can always get the teacher's guidance through the Internet. Moreover, interactive learning, rich three-dimensional graphics display, language explanation and other multimedia content on the network make learning easy and interesting, which is beyond the reach of any textbook! Besides, the usage rate and content of English are the most on the Internet, accounting for 84% and 90% respectively, which will encourage us to learn English more actively. Is this not good?
3. Reality. The urgent task is to establish computer classrooms in every primary and secondary school, popularize network knowledge, promote primary school students to surf the Internet at home, and realize distance education and knowledge sharing, so as to cultivate primary school students' interest and awareness in learning and applying information technology and cultivate our ability to acquire, analyze and process information. Look around us again. The school website is depressed. Didn't Mr. Wang also suggest you visit the school website more? Isn't the website of the class in full swing? If the Internet is not good, why build these websites?
Indeed, as a new thing, we believe that the network has some disadvantages, but primary school students, with the education of the school, the correct guidance of teachers and the guidance of parents, will certainly enable us to use the network as a tool with a correct attitude. 2 1 century will be the information age, and we will be the pillars of the future motherland. Understanding and mastering computer network knowledge is the most powerful weapon to break through the future information age. Let's believe that every effort we make today will eventually converge on the Shahui Tower and will eventually be rewarded. So I once again state our point of view: the advantages of primary school students surfing the Internet outweigh the disadvantages!
Positive debate: Hello, teachers, classmates and friends of the other side! The internet has brought countless benefits to mankind. The appearance of network is the symbol of the progress of modern society and the development of science and technology. Illiteracy in the modern sense no longer refers to those who can't read, but people who don't understand that computers are divorced from the information age. In ancient times when science was underdeveloped, people often fantasized that they could know what was going on in the world without leaving home. Now, the rapid spread of information has made this fantasy a reality. As a pupil of 2 1 century, can you still read only sage books and not know what's going on in the world?
Another debater cited various examples to prove the disadvantages of the Internet to our primary school students. However, I want to say that everything will always have some disadvantages in the new stage. If we stifle it just because of a flaw, aren't we missing a lot of things that are indispensable now?
