The reason why a debate can become a debate means that it is fair to both sides. If you think that the development of science and technology has only advantages and no disadvantages, then you will have a great chance of losing.

I have typed this debate or a similar topic twice, but I don't know it four times after reading it three times.

briefly.

Introduction: First of all, it should be clarified that science and technology is a double-edged sword, which brings convenience to people, but it also causes damage to the environment. We never deny this, but if human beings want to develop, it will inevitably drive the progress of science and technology. Americans suggest that the earth can only accommodate 4 billion people, while the actual population of the earth has exceeded 6 billion. If the gap of 2 billion is not solved by science and technology, can they live in virgin forests?

just think, which of today's abundant energy supply and developed communication network does not need technology to complete? If the other classmate really cries bitterly that the development of science and technology does more harm than good, then your point of view is called retrogression, not progress.

another reason why we believe that the advantages outweigh the disadvantages is that technology will destroy the environment, but it can also create the environment and rebuild a beautiful home.

The proposal of sustainable development means that the environment has also become one of the topics that science and technology development should pay attention to. Developed countries are the main sources of environmental deterioration, and they already have abundant economic capital, so their sustainable development is to slow down the development of science and technology and focus on protecting the environment, while the sustainable development of developing countries is to avoid damaging the environment as much as possible and carry out the process of science and technology at the same time.

...

To sum up, we believe that the advantages of scientific and technological development outweigh the disadvantages.

attack and defense: you can set traps to trap the other side.

according to each other's logic, do you want to do something that does more harm than good?

If you want to, then don't come to school, because taking the bus will emit harmful gases, which will aggravate carbon dioxide emissions, and learning science and technology will make our society go backwards.

If you don't, then aren't you drinking poison to quench your thirst? Isn't it a bit puzzling to do what you know you can't do?

in your opinion, the disadvantages outweigh the advantages. Besides the environmental concerns, what else?

isn't this giving up a forest for a tree?

do you know what the theme of this year's Expo is?

Cities make life better. For this goal, are we using science and technology to improve the environment and alleviate the evil consequences caused by environmental damage?

For such questions, you can look up the arguments in previous debates.

I hope it helps you. Answer: Angel in a daze | Level 5 | 2111-4-11 16:11

Everything has two sides.

actually, the advantages should still outweigh the disadvantages. Since there are disadvantages, I don't have to develop technology. Think again, we are living well under this technology now! But technology will still have some disadvantages. For example, computers can enrich our spare time and make the world a "global village". Computers also have radiation, but who do you see who doesn't play because of the radiation of computers? Refrigerator can keep our leftovers from spoiling temporarily and reduce unnecessary waste. However, how many people know that the radiation of refrigerator can make children get hematologic cancer! But we can reduce those unnecessary injuries. If we surf the Internet healthily and control the time of surfing the Internet, won't the radiation be small? Refrigerator We try not to put the refrigerator in the children's bedroom, can't it greatly reduce the harm to children?

Facts show that technology and life are indispensable to both. If we only pay attention to one item, the consequences will be unimaginable!

Nowadays, with the development and progress of science and technology, everyone can enjoy what those historical figures can't enjoy. Everyone has greatly neglected the development of science and technology, the acceleration of people's living pace and the improvement of living standards.

1 The environment has been seriously damaged, and the emissions of air conditioners and automobile exhaust have caused ozone hole, global warming, land desertification and so on. And the amount of plastic is increasing day by day. In 1996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than < P > 21%, especially in the garbage of cities, major traffic routes and tourist attractions.

According to the survey, the annual output of domestic waste in Beijing has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of

48%. The plastic content of garbage in coastal cities is higher, reaching 8-11%. The waste

plastics account for more than one-third of the garbage by volume, which greatly increases the difficulty and cost of

garbage disposal. Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will provide a hotbed for mosquitoes, flies and < P > bacteria to survive and breed; If buried underground, it will easily pollute groundwater, hinder the growth of plant root system, destroy soil quality and affect crop harvest; If it is incinerated by fire, a variety of poisonous gases < P > will be produced. "White pollution" has become a major public hazard endangering China's social environment at present.

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 becoming more and more insecure. Now tens of thousands of criminal acts occur every day on average. Most of their criminal means are related to the current new technology, especially gun crimes, which are hard for ordinary people to prevent. As we can already see from the Second World War, 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. On August 6, 1945, an atomic bomb was dropped over Hiroshima, Japan. In an instant, a huge mushroom cloud was rolled up about 11,111 kilometers above the ground, and then hundreds of pillars of fire fell from the sky. In an instant, a beautiful city became a sea of fire. Hundreds of millions of degrees of high temperature turned everything into ashes ... nothing grew in the center of the explosion for decades ... < P > 4. The physical quality of human beings is not as good as before. With the development of science and technology, the emergence of various means of transportation such as gas cars, trains and airplanes has made great changes in human daily life, and human beings no longer always rely on their own legs, so the physical quality of human beings is not comparable to that of the past. In the past, Xiang Yu "pulled out mountains and rivers."

5. With the development of science and technology, computers have begun to spread among the masses, but for some teenagers who have no adult supervision and weak self-control, computers are a very dangerous place. There are the following hazards:

(1) Students are addicted to the Internet, unable to extricate themselves, and spend a lot of time surfing the Internet, thus affecting their academic performance.

(2) Some students who surf the Internet for a long time are prone to autism, and indulge in fantasy all day and get divorced from reality. However, when he really faces the society and people, he will shrink back because of the problems of imagination and distance, and dare not communicate with others normally.

(3) Many middle school students blur the difference between real people and game objects by playing some violent games, and often treat people around them unconsciously by The Imitation Game.

(4) surfing the internet for a long time requires a lot of money. When there is no money, people with weak self-control will take illegal measures to get money by hook or by crook, and thus embark on the road of crime.

(5). Internet cafes are often hiding places for unemployed people, drug addicts and criminals. Staying in these places for too long will often lead to accidents or be tempted.

(6) Bad information and cyber crimes on the Internet pose harm and threat to teenagers' physical and mental health and safety.

(7) The Internet makes many teenagers indulge in the virtual world of the network, divorced from reality, and also makes some teenagers neglect their studies. Respondent: lilingfei13239 | Level 3 | 2111-4-11 21:22

Lida, because human beings will step into the information age, and the network will be more and more strongly involved in our lives 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!

(rebuttal after the debate of the opposing side)

The benefits brought by the Internet to mankind are countless, and the appearance of the Internet is a 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 used to fantasize about knowing what was going on in the world without leaving home. Now, the high speed of information has turned this fantasy into reality. As a primary school student in the 21st century, can you still read only sage books and not know what's going on in the world?

The other 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 maladies in the new stage. If we kill it just because of a little flaw, then we are missing a lot of things that are indispensable now.

The speed of the Internet also has its advantages. Through the Internet, we can know some latest news in time. Through the internet, we can visit primary schools all over the country in just a few hours, look up the information we need in the online library, and with the help of online information, we can finish our studies calmly, and we can know the results immediately after the exam. If we have any questions, we can ask the teacher for guidance at any time by email. Take SARS, which impressed everyone the most. During the SARS period, some schools in Guangzhou and Beijing had to stop classes. In order to implement synchronous teaching, people invented the online school. Every week, the teaching content of the online school was consistent with the progress of the school curriculum, and we could receive a comprehensive education all over the country by surfing the Internet. Isn't that good? Because of the above viewpoints, we firmly believe that the advantages of surfing the Internet outweigh the disadvantages. Respondents: Mi Xiaosha | Level 1 | 2111-4-11 21:52

think that the disadvantages are great, because how many amazing changes have taken place in the world when mankind entered the 21th century. While people are delighted with the rapid development of science and technology, they have experienced better uneasiness and even disasters. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to directly bring mankind to the gate of hell.

The epidemic of SARS in p>2113, including all the speculations about SARS, is directly related to the global issue that people are increasingly concerned about: biosafety. Biosafety is a scientific and technological system for the detection, evaluation, monitoring, prevention and treatment of biological hazards. It is a new frontier discipline that studies the impact of various biological factors on human health and applies existing theoretical knowledge, technology, engineering design and equipment to prevent people engaged in related work, laboratories and the environment from being harmed by potentially infectious substances and biological toxic substances. Biosafety problems are at least manifested in the following aspects:

Great harm of infectious diseases

Infectious diseases include human, animal and plant infectious diseases, especially human infectious diseases are the most important biosafety problems, and infectious diseases are still the first cause of death in the world. In China, infectious diseases still seriously threaten people's health and national security. The prevalence of SARS is a strong proof. In addition, infectious diseases such as hepatitis, tuberculosis and influenza are still prevalent or erupting in some parts of the country and some countries and regions in the world every year

The potential threat of biological weapons and bioterrorism

In the 21th century, the whole international community made unremitting efforts to ban biological weapons and made some progress. However, in the 21th century, the potential threat of biological weapons has greatly increased, and some countries and regions may continue to research and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and the bioterrorism marked by the "anthrax incident" in the United States has posed a real threat to international security. Yuan Guoyong, head of the Department of Microbiology at the University of Hong Kong, was the first scholar to isolate coronavirus and found that coronavirus variant was the pathogen of SARS. SARS virus belongs to RNA virus, and the characteristic of this virus is that it is easy to recombine with other virus genes and then become a new virus. Moreover, many experimental results also show that the new virus produced in this way will be more toxic than the parent virus. Coronavirus can be found in many animals, and this virus is prone to mutation and extremely dangerous. Therefore, Yuan Guoyong recognized
