The way of life of human beings would not have changed much 200,000 years ago compared with 100,000 years ago, 3,000 years ago compared with 2,000 years ago, and 600 years ago compared with 500 years ago. However, present-day people and ancient people have in fact long been different from what they were in the past, and even now, compared with 100 years ago, they are completely different. What drives the development of human history? What started mankind on a new way of being?
I say, this is science and technology, is the development of science and technology to promote the process of human beings, is the development of science and technology to make human beings have this 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, look at the four great inventions, unique; look at the astronomical calendar, marveled at; look at the Zhaozhou Arch Bridge, the design is exquisite; peep "Materia Medica", the Oriental canon; look at the value of pi, seven decimal; look at the Silk Road, the development of the economy; end of the blue and white porcelain, famous overseas. Scientific and technological development is the road to a strong country, scientific and technological development is the first driving force for the progress of the Chinese nation, no science, where we are today's happy life? Without science and technology, where we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can we eat the hybrid two? How can we wear cotton clothes, how can we live in high-rise buildings?
Ask, the development of science and technology benefits or disadvantages? There is no doubt, of course, is the benefit! What is the explanation? There is no need to explain! Chinese civilization eight thousand years of history and civilization is ironclad, history is changing every moment, technology is developing every moment. Human beings have learned to utilize or cook food from the primitive life of drinking blood and hair, from relying on nature to breeding and raising, from unarmed iron to metallurgy and stone smelting, isn't this all progress, isn't this all development? If the disadvantages outweigh the advantages, then why do human beings still coincidentally choose progress? Only progress can make tomorrow better!
A person who does not make progress is pathetic, a country that does not make progress is downtrodden, a world that does not make progress is dark. Only in continuous progress can human life be sublimated. Man is small, man is fragile, he does not have a huge body, no ox-like strength, no turtle's hard shell. But God gave mankind a clever brain, a pair of hard-working hands, mankind did not sit back and enjoy the success, but chose to continue to progress, can only stand in the top of the food chain today.
Let's compare today's life with that of 100,000 years ago, we are supreme; compare today with that of thousands of years ago, we are condescending; compare today with that of hundreds of years ago, we are happy and comfortable; compare today with that of tomorrow, the future is bright and beautiful. Thousands of years, from the horse-drawn carriage into cars, trains, airplanes; from kerosene lamps into incandescent lamps, neon lamps, energy-saving lamps; from the ends of the earth into the near at hand, video chatting, a little bit of the mouse to know the world.
We are happy, we are lucky, we caught up with a high-speed development of science and technology, an era full of high-tech, it is not only our ancestors in the evolution of the choice of development, choice of progress, but also includes all the unremitting efforts, hard work, how many of us today's day when the hard-working scientists with the wisdom of the even life in exchange.
Because of Faraday, we live around the full of a variety of electrical appliances; because of Darwin, because Mendel, we can better understand themselves, cognitively; because of the magpie, because of Hua Tuo, because Li Shizhen, our life can be guaranteed.
Aren't they the ones who gave us everything around us in exchange? Life is so comfortable, life is so cozy, life is so wonderful, our average life expectancy is 30 years higher than in ancient times, we don't even have to leave our homes to visit our friends and relatives, isn't it all because of the benefits brought to us by the development of science and technology?
So, science and technology change history, we explore the development of science and technology benefits or disadvantages is no need to question, because it is the benefits! Lei big! Profit big! You say that the development of science and technology has brought about atmospheric pollution, you say that the development of science and technology has produced white trash, you say that the development of science and technology has formed a warming of the temperature ...... All things cannot be perfect, the brighter the place behind the shadows the darker, but on the basis of these you conclude that the development of science and technology has done more harm than good? "The world is different things are different" times are different, the problems encountered are different, and then the air pollution, the provinces and cities have launched a preventive plan; white trash, unified treatment; automobile exhaust caused by warming scientists have also developed a solar-powered cars. Look at now, solar water heaters, solar air conditioning, solar batteries ...... environmentally friendly and economical solar energy has gradually entered thousands of households, this is not technology in development?
While there are drawbacks, but compared to the benefit of mankind, environmental protection homes of the concept of scientific and technological development, irrelevant, as long as there are drawbacks, scientists will likewise find a way to solve, we can not choke on food, the pace of scientific and technological development will not stop for a moment. Scientific and technological development, there is no excuse, is the benefit of the big, the only answer to this question! Just because technology has been progressing, science has been developing, cunning sophistry, generalized words, unreasonable nonsense can not change this truth. If you say that technological advances do more harm than good, ask, can you go a week without coming to class in a car, without using a neutral pen, without using a ballpoint pen, without using a fountain pen? Can you go a week without watching TV, listening to the news, reading a newspaper, reading a book, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? No pasta? No drinks? Can't can't, you can't and can't be able to, because technology is already closely related to you, already inseparable from you! In ask, if you write a letter to the President, said that the proposal to stop all scientific research activities, everyone is to give you flowers, or that board special pat you?
Technology changes history, good, without the development of science and technology, our lives are unimaginable, our days are dark, is the development of science and technology to save us, is the science of our rescue from the age of fire and water. We should respect him with a heart of reverence, how can we say that the development of science and technology is full of drawbacks?
Technology changes history, knowledge changes destiny. We have entered the 21st century, into an era full of high-tech. Science has changed our lives, science has changed our destiny. "Knowledge is power", our Chinese people **** and the country, 1.3 billion people of the great country, why can the world in front of the chest up? Because our technology is constantly developing! Our science and technology in constant progress!
The benefits of technological development outweigh the disadvantages, which is an unchanging theme!
The advantages and disadvantages of the development of science and technology
Conclusion: the development of science and technology is important, but can not be reasonable and normal use of the premise to develop, the development of first of all must be to purify the mind, only the individual's mind and heart to get the development and improve the development of high technology can be permanently beneficial to the development of mankind, the harmony of nature!
Cons: the above said that each of us look higher and farther away, which makes us see is just far away from the higher things to explore to pursue, ignoring the immediate do, like those in history who want to find a long life can not be some of the monarchs, drugs are used to manage the disease, the results of their blind investment to go in order to achieve some of the impossible to achieve something, and as a result, the harm to themselves and to the people, as well as the public. The result is that they have harmed themselves and the people, and the people now see the macro scene in the movie, chilling the emperor's funeral and the so-called miracle of the world.
The development of science and technology has brought both convenience and disaster. The first is that we can go to the place we want to go, people are constantly exploring, in the future may even back to the "solar center" will be overthrown. In the technological development and progress of the present no one can enjoy those historical figures can not enjoy things, each newcomer to the world has a different understanding of our vision farther!
Let's compare today's life with that of 100,000 years ago, we are supreme; compare today with that of thousands of years ago, we are condescending; compare today with that of hundreds of years ago, we are happy and comfortable; compare today with that of tomorrow, the future is bright and beautiful. Thousands of years, from the horse-drawn carriage into cars, trains, airplanes; from kerosene lamps into incandescent lamps, neon lights, energy-saving lamps; from the ends of the earth into the near at hand, video chat, a little bit of the mouse to know the world. This is the power of science and technology!
So, science and technology change history, we explore the development of science and technology is not necessary to question the advantages or disadvantages, because it is the advantages! The advantages are great! The advantages are great! You say that the development of science and technology has brought about atmospheric pollution, you say that the development of science and technology has produced white trash, you say that the development of science and technology has formed a warming of the temperature ...... All things cannot be perfect, the brighter the place behind the shadows the darker, but on the basis of these you conclude that the development of science and technology has done more harm than good? "The world is different things are different" times are different, the problems encountered are also different, and then say the air pollution, the provinces and cities have launched a preventive plan; white trash, unified treatment; automobile exhaust caused by warming scientists have also developed solar-powered cars. Look at now, solar water heaters, solar air conditioning, solar batteries ...... environmentally friendly and economical solar energy has gradually entered thousands of households, this is not technology in development?
The development of science and technology, there is no excuse, is the profit big, the only answer to this discursive question! Just because technology has been progressing, science has been developing, cunning sophistry, generalized words, irrational nonsense can not change this truth. If you say that technological advances do more harm than good, ask, can you go a week without coming to class in a car, without using a neutral pen, without using a ballpoint pen, without using a fountain pen? Can you go a week without watching TV, listening to the news, reading a newspaper, reading a book, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? Not eat pasta? No drinks? Can't can't, you can't and can't be able to, because technology is already closely related to you, already inseparable from you!
May 12, 2008 14:28, I believe we must not be unfamiliar with this time. It was then that a massive earthquake measuring 8.0 on the Richter scale struck Wenchuan County in Sichuan Province, and we all know the back story. But think about this, folks: What brought the liberation officers and soldiers to the disaster area by water? What sent relief supplies to the disaster area through airdrops? What is the first time to open the highway to Wenchuan? What helped people saw through the steel bars and dig out the injured? What helped the doctors bring back the injured from the death line? --It's the submarine boats, helicopters, excavators, chainsaws and medical equipment. This, then, is the power of science and technology! We should continue to develop technology and build houses that can resist earthquakes so that more people can be spared. This natural disaster reinforces our view that the development of science and technology will be beneficial in the future!
Darwin once said, "The survival of the fittest is a law of nature." The panda's ability to reproduce was already weaker than other animals, plus the habit of being picky about food and living alone, making the panda on the verge of extinction. Look at the cockroaches, even if the atomic bomb exploded, the cockroaches there are still there "running for prosperity"? Moreover, science can help pandas by healing their wounds and delivering babies. How nice!
With the development of science and technology, human civilization has taken a big step forward, from the former horse-drawn carriages to automobiles, from the former oil lamps to electric lamps ......
Now, people's lives have become better. Use the telephone to speed up communication, use cars and motorcycles to speed up the rhythm of life, use electric cookers and gas to make delicious meals ......
Television is indispensable in life. We can watch the news and learn about what's going on at home and abroad; we can watch cartoons and relax; we can also watch programs and performances without going to the site; for example, when the mascot of the Olympic Games was unveiled this time, we could watch the broadcast at home.
Computers are more widely used in all walks of life, we send a letter to Brazil in Haining, as long as a few seconds each other can receive. We can chat with friends and family on the Internet and the north and south of the world, games; can read the news on the Internet, watch movies, listen to music; can listen to the teacher's classes, look for information, but also can not leave the house shopping, medical care, first aid ......
Can be so said, technology and we are closely related. With this developed technology, our life is faster and more convenient, colorful.
We can go where we want to go, people are constantly exploring, in the future may even back to the "solar center" will be overturned. In the technological development and progress of the present no one can enjoy those historical figures can not enjoy things, each newcomer to the world has a different understanding of our vision farther!
1. Necessity. This is an era of knowledge-based economy, information is expanding and exploding at an unprecedented rate, the future world is the world of the network, to keep our country in this information world to keep pace with the times, as the main force of the 21st century we are bound to be able to adapt to this high-tech society faster, to have the ability to obtain effective scientific information from the outside world in a rapid, timely manner, with the ability to disseminate scientific information, this is the quality of science. This is the quality of science. The Internet is precisely adapted to this requirement. Deng Xiaoping grandfather did not say: "computer to start with the children"?
2. Practicality. Network world resources **** enjoy, it is like a treasure bowl, an inexhaustible "rich gold mountain", who diligently cultivate labor on this gold mountain, who will have something. You can find the fastest learning materials, you can learn more knowledge outside the classroom, and flexible use of knowledge in the classroom, to promote the development of thinking, cultivate the creativity of primary school students. The Internet can also go beyond the time and space and economic constraints, in the online education of the famous schools, there are any problems, you can also get the teacher's guidance through the network at any time. Moreover, the interactive learning on the Internet, rich three-dimensional graphic display, language interpretation and other multimedia content, making learning easy and interesting, which is impossible to have any textbooks! In addition, the network to the English usage and content for the most, respectively, 84% and 90%, which will motivate us to learn English more actively, this is not good?
3. Reality. Each primary and secondary schools to establish computer classrooms, popularize network knowledge, promote elementary school students' family Internet access, the realization of distance education and knowledge **** enjoyment is to cultivate primary school students to learn and apply the interest and awareness of information and technology, and cultivate our ability to obtain, analyze and process information, which has become imperative. Look around us, the school's website is not engaged in the red hot, Mr. Wang did not also suggest that we go to the school's website to take a look? Isn't the class website in full swing? If the Internet is not good, why build these sites?
It is true that as a new thing, we believe that there are some disadvantages of the network, but elementary school students in the school under the education, in the teacher's correct guidance and parental guidance, will be able to make us with a correct mindset to the application of the network of this tool. 21st century will be the age of information, we will be the future of the country's pillars. Understanding and mastering the knowledge of computer network is the most powerful weapon to break into the future information age. Let's believe that the efforts we put in today will be rewarded in the end. Therefore, I once again state our point of view: the advantages of Internet access for elementary school students outweigh the disadvantages!
Forward two defense: Teachers, students, the other side of the defense everyone good! The benefits of the Internet to mankind can be said to be countless, the emergence of the network is a sign of the progress of modern society, the development of science and technology. The modern sense of illiteracy no longer refers to those who can not read and write, but do not understand the computer out of the information age. In the ancient times when science was not developed, people had fantasized that they could know everything about the world without leaving their homes, and now the high speed of information has turned this fantasy into reality. As a student of the twenty-first century, can we still only read books and not hear the world?
The other side cited various examples to prove the disadvantages of the Internet for our students. However, I have to say that anything in the newborn stage will always produce some uncomfortable disadvantages, if we just because it a little bit of small defects and kill it, then we are not a lot of essential things less now?
