Mankind will enter 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 necessarily 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 elaborate 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 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 us 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!
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!
Debate words-scientific and technological development, benefiting universities
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. -The benefits of technological development, Wu Si.
Yes, the development of science and technology in our country is getting bigger and bigger, which also brings a lot of convenience to the people. Television, computers, air conditioners and game consoles have added a lot of fun to our lives, so I think the development of science and technology is beneficial.
From the medical point of view: the emergence of various modern technologies and laser surgery has saved many people's lives; Astronomy: the invention of artificial earth satellites and spacecraft, such as meteorological satellites, can accurately predict future weather changes and provide convenience for human production and life; In terms of human life, various electrical appliances make people's lives very comfortable, such as air conditioning, which is warm in winter and cool in summer. Of course, the progress of science is inevitably accompanied by negative effects, but the positive side accounts for the vast majority after all.
From the internet, there are people who surf the internet; With people surfing the Internet, some people talk about the advantages and disadvantages of surfing the Internet. Today, as a college student, what do I think of college students surfing the Internet? I think it should be divided into two.
The network was originally used in enterprises to find the information needed by the company and negotiate business. At this time, the network has not been popularized, but its role is positive. At this time, the network is not perfect, but I don't think there are any advantages or disadvantages.
With the progress of technology, the network is becoming more and more perfect and popular. In order to better meet the needs of the public, there are online games, QQ and various sections. As a result, more people surf the Internet, including college students. There are various reasons for college students to surf the Internet. Some pass the time by looking for netizens; Some stay up late for online games; Some people "enrich" their lives for online movies. Of course, there are also for learning. I heard with my own eyes that an architecture student had to stay up for two nights to paint. Let's not talk about whether his behavior of staying up late is improper, but only about his use of the internet. He is using the internet. I want to interject, what is "utilization rate"? I think, here, use is not a derogatory term, but a positive and effective use. Today, with the development of science and technology, with the help of computers and the Internet, many things that could not or were not easy to do in the past can be done.
If you don't have a computer, PSP or WIIL, can you imagine that your life can be much more boring than it is now, like those students who are rich and powerful at home and can't live without video games every day, or even adults, can they leave the development of science and technology? Of course, personally, playing games is not good. But the development of science and technology can also let foreigners know that China has become stronger, so don't try to bully our country and the G8.
Debate on the advantages and disadvantages of scientific and technological development: the disadvantages are great
Nowadays, the rapid development has brought convenience to human beings, but it will hurt many things and pollute the environment in the process of development, which is the most direct and conspicuous disadvantage. However, more than that, species extinction is accelerating, which is caused by environmental pollution and human hunting, and also belongs to the disadvantages of scientific and technological development. Personal safety is becoming more and more 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, so that ordinary people can't prevent it. 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 being comparable, and may even lead to the fate of human extinction. Not only that, but also the physical quality of human beings is not as good as before. With the development of science and technology, the emergence of gas cars, trains, planes and other means of transportation has greatly changed human daily life. Humans no longer always rely on their own legs, so the physical quality of human beings is not the same as before. If this situation continues to develop, it may make people's limbs atrophy and make people appear new forms. Let me make my point again. The disadvantages of scientific and technological development outweigh the advantages! All kinds of emerging 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't keep up with the mutation speed of virus, and maybe one day mankind will perish from a great plague.
I think the most important thing in this debate is not to list all kinds of disadvantages brought by science and technology to mankind, because if your eyes are only fixed on the disadvantages, then the other party is likely to seize this point and attack you: your opponent, you always list all kinds of disadvantages of science and technology, as if the development of science and technology has only brought disasters to mankind, so why are we still emphasizing that science and technology is the primary productive force now? Why should mankind continue to develop science and technology?
The key to answering this question lies in your understanding of the debate. The essence of this understanding lies in: Why should we find out the disadvantages brought by technology? This is the key to your point of view. Why? I remember a saying: technology 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. At this time, we emphasize the pain and disaster brought by science and technology to mankind precisely for the purpose of maximizing the positive role of this double-edged sword and benefiting mankind, not the other way around. The so-called good medicine is good for the disease, because thinking about science and technology rationally and comprehensively can keep science and technology under the control of human beings all the time and will not harm human beings in turn.
After the viewpoint is established, there are naturally some necessary examples. In fact, the example is very good: the development of atomic physics theory has enabled mankind to master nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Nagasaki, and brought about a "terrible peace" for mankind for 50 years. For the first time, human beings have the ability of self-destruction. There are also endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous (please search online for specific data). The development of chemistry has given us unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why are so many children suffering from leukemia in our country now? Very important factors are chemical adhesives used in home decoration and ozone-destroying freon. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too much interference, and the earth began to catch a cold and have a fever. The development of biotechnology has given us the power to create life monopolized by God before, but it has also brought about ethical disorder. In short, scientific progress is always accompanied by corresponding disadvantages and dangers. Today, we must face up to these negative effects, otherwise we humans may eventually be destroyed in our own hands.
The development of science and technology in grade six is good or bad.
Students from the opposing side may think from the perspective of "great harm" and may put forward some reasons like this:
(1) The emission of automobile exhaust has caused environmental pollution and seriously affected people's health. (2) The appearance of entertainment facilities such as TV makes the communication between people less and less, and the human feelings are weak.
(3) The emergence of the Internet has given some people the opportunity to disrupt people's production and life ...)
Disadvantages: 1: Environmental pollution. This is the most direct and obvious disadvantage.
2. Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.
3. Personal safety is increasingly insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to the current new technology. 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.
Human's physical quality is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. 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. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people appear.
5. All kinds of emerging 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.
