What are the examples and materials of scientific and technological development?

mankind will step into the information age, and the network will be more and more strongly involved in our lives, getting closer and closer to our primary school students. Is it beneficial or bound to be great for primary school students to surf the Internet? We firmly believe that the advantages of primary school students surfing the Internet outweigh the disadvantages. I will expound our views from three aspects:

1. Necessity. This is an era of knowledge economy, information is expanding and exploding at an unprecedented speed, and the future world is a world of networks. As the main force in the 21th century, we 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 in time, and have the ability to spread 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, which is like a cornucopia, an inexhaustible "golden mountain of wealth". Whoever diligently cultivates and labors on this golden mountain will gain something. You can find the study materials from them as quickly as possible, learn more knowledge outside the classroom, and use the knowledge in the classroom flexibly to promote the development of thinking and cultivate the creativity of primary school students. Surfing the internet can also transcend the constraints of time and space and economy, and receive education from famous schools online. If you have any problems, you can always get guidance from teachers through the internet. Moreover, interactive learning, rich three-dimensional graphic display, language explanation and other multimedia content on the Internet make learning easy and interesting, which is impossible for any textbook! In addition, the usage rate and content of English are the most on the Internet, which are 84% and 91% respectively, which will encourage us to learn English more actively. Isn't that good?

3. Reality. It is imperative 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 in order to cultivate primary school students' interest and awareness in learning and applying information and technology, and cultivate our ability to acquire, analyze and process information. Look around us again. The school website is not booming. Doesn't Mr. Wang also suggest that you visit the school website more often? Isn't the website of the class also in full swing? If the internet is not good, why build these websites?

Indeed, as a new thing, we believe that the Internet has some drawbacks, but primary school students' education at school, the correct guidance of teachers and the guidance of parents will surely enable us to apply this tool with a correct attitude. The 21th century will be the information age, and we will be the pillars of the motherland in the future. Knowing and mastering computer network knowledge is the most powerful weapon to break through the future information age. Let us believe that every bit of effort we have made today will eventually converge on the Shahui Tower and will eventually be rewarded. Therefore, I once again state our point of view: the advantages of primary school students surfing the Internet outweigh the disadvantages!

The way of life of human beings will not change much 211,111 years ago compared with that of 111,111 years ago. Compared with 2111 years ago, there will not be much change before 3111; Compared with 511 years ago, 611 years ago will not change much. However, today's people and the ancients are actually not what they used to be, even now compared with 111 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 science and technology. It is the development of science and technology that promotes the progress of mankind, and it is the development of science and technology that makes mankind have this brand-new and beautiful life. Throughout the ages, which dynasty and which 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 at it; Look at Zhaozhou Arch Bridge, with exquisite design; A glimpse of Compendium of Materia Medica, an oriental masterpiece; Look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; The blue-and-white porcelain ware is famous overseas. Scientific and technological development is the road to a strong country, and it is the first driving force for the progress of the Chinese nation. Without science, how can we live a happy life today? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can we eat hybrid 2? How can we put on cotton clothes and live in tall buildings?

q, is the development of science and technology more beneficial or harmful? Undoubtedly, it is of course Lida! What is the explanation? No need to explain! The 8,111-year history of Chinese civilization is irrefutable evidence. History is changing all the time, and technology is developing all the time. Humans learn to use or cook food from primitive life, from relying on nature to breeding, from unarmed to metallurgical smelting. Isn't this progress, isn't this development? If the disadvantages outweigh the advantages, then why do human beings choose progress in unison? Only progress can make tomorrow better!

it's sad that a person doesn't make progress, a country doesn't make progress and it's declining, and a world is dark without progress. Only through continuous progress can human life be sublimated. Man is small, man is fragile, he has no huge body, no strength like an ox, and no hard shell of a turtle. However, God has given human beings a smart brain and a pair of hard-working hands. Instead of enjoying the success, human beings have chosen continuous progress to stand at the top of the food chain today.

Let's compare today's life with that of 111,111 years ago. 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. 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 because of all people's unremitting efforts and hard study. How many hard-working scientists have exchanged 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 better understand ourselves 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 31 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 brought by the development of science?

Therefore, science and technology have changed history. It is not necessary to question whether the development of science and technology is beneficial or harmful, because it is beneficial! Lida! Lida! 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 brighter the place, the darker the shadow behind it, but on this basis, you can conclude that the disadvantages of science and technology development outweigh the advantages? Different times lead to different problems. Besides air pollution, all provinces and cities have put forward preventive plans. White garbage, unified treatment; Automobile exhaust causes the temperature to warm, and scientists have also developed solar-powered cars. Look at the present, solar water heaters, solar air conditioners, solar cells ... environmental protection and conservation of solar energy has gradually entered thousands of households, isn't this the development of science and technology?

Although there are drawbacks, compared with the concept of scientific and technological development that benefits mankind and protects the home, it is irrelevant. As long as there are drawbacks, scientists will also try to solve them. We can't give up eating because of choking, and the pace of scientific and technological development will never stop. There is nothing wrong with the development of science and technology, that is, to benefit greatly, which is the only answer to this argument! Just because science and technology have been advancing, science has been developing, and cunning sophistry, general words, and unreasonable pestering 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, a gel pen, a ballpoint pen and a 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 you not eat the developed hybrid rice for a week? No pasta? No drinks? You can't, you can't and you can't, because technology is closely related to you, and it is inseparable from you! Now, if you write to the chairman and suggest stopping all scientific research activities, will everyone give you flowers or will the board shoot you exclusively?

It is true that science and technology have changed history. Without the development of science and technology, our life would be unimaginable. Our days were dark. It was the development of science and technology that saved us, and it was science that saved us from the fiery age of water. We should respect him with a heart of awe. How can we say that the development of science and technology is full of drawbacks?

technology changes history, and knowledge changes destiny. We have entered the 21th century and an era full of high technology. Science has changed our lives, and science has changed our destiny. "Knowledge is power". Why can we, the Chinese people, a vast country with a population of 1.3 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!
