Unit 5 oral communication class in the second volume of the sixth grade "Is the development of science and technology beneficial or harmful?" The positive side "the advantages outweigh the disadvantages" needs to be summarized. Nowadays, with the rapid development of science, many high-tech products are constantly emerging. Computers, cars, dishwashers and washing machines have entered the lives of ordinary people. They do bring a lot of convenience to our lives, but at the same time they gradually lose the basic abilities of human beings. With computers, people no longer think with their brains, because they can do it with computers; With cars, people are no longer used to walking, walking, but driving for a ride; With the dishwasher, people no longer wash dishes by hand. Maybe one day, people will forget how to wash dishes. The development of science and technology is mixed. Happily, it provides the greatest convenience for our life. What is worrying is that one day computers will replace the human brain and machines will replace the hands. By then, the world will no longer be dominated by people who think they are smart, but machines invented by human beings! So I think: the development of science and technology will inhibit the all-round development of people!

Another example is airplanes, rockets, networks and satellites, which originally appeared for military wars. The same technology is used as an accomplice to the destruction of mankind while benefiting mankind. So we think that the disadvantages of scientific and technological development outweigh the advantages! Agree with 0| Comment 2011-5-2 20:12 Enthusiastic users.

Yes, Lida agrees with 0| comment 2011-5-312:17 enthusiastic users.

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? Because 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. God has given mankind a clever brain and a pair of hardworking hands. It is precisely because human beings choose to make continuous progress instead of enjoying success that they can stand at the top of today's food chain.

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, it is beneficial! Rita! Rita! You said that the development of science and technology brought air pollution, you said that the development of science and technology produced white garbage, and you said that the development of science and technology caused the warming of the temperature ... Everything can't be perfect, so you can conclude that the development of science and technology does more harm than good? 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, which is profitable! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth. 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 can People's Republic of China (PRC) (PRC), a vast country with a population of 654.38+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!

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. So the advantages of science and technology law outweigh the disadvantages.

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, you can't, you can't and can't, because technology is closely related to you and inseparable from you! Now you write to the chairman and suggest stopping all scientific research activities. Will people send flowers or step on you?

(1) The invention of vehicles such as automobiles has made people travel more convenient, time-saving and labor-saving. (2) The invention of telephone and mobile phone makes people's communication more convenient. (3) Computers and faxes have liberated people from heavy work, and the emergence of the Internet has broadened people's horizons. ...

Science and technology is the primary productive force-Deng Xiaoping

Thanks to science, it not only makes life full of happiness and joy, but also gives life a pillar and self-esteem. -Pavlov physiologist

The benefits brought by the rapid development of science to the whole society need to make up for the harm it has caused. -Stamp statesman How many amazing changes have taken place in the world since mankind entered the 2 1 century. While people are delighted with the rapid development of science and technology, they have also experienced better anxiety 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 door of hell. The invasion of various viruses, the exhaust gas behind cars, the exhaust gas from factories and so on. Don't invade our beautiful home. Why are our homes threatened, why are trees cut down in large numbers, and why is the air not fresh? These are all kinds of criminal evidence brought by science and technology. Modern science and technology have brought us some comfort and convenience, but at the same time, they have also brought about a wide range of influences. How can human beings live comfortably without a beautiful environment? If people don't remedy their mistakes quickly, mankind will eventually be destroyed by science and technology.

We don't deny that the development of science and technology has brought benefits to our lives. However, we believe that the disadvantages brought by technology outweigh the benefits. First of all, although cars are convenient for us to travel, the exhaust gas from archways has caused environmental pollution and affected human health. Secondly, the appearance of entertainment facilities such as television brings convenience to people, but it also virtually blocks the communication between people, which is weak. There is also the emergence of the Internet. There is no denying that some lawless elements have the opportunity to disrupt people's lives and wait for a series of side effects brought by your so-called high technology. How can you just sit back and watch?

What the other debater just said is just a hypothesis. Please come back to reality and ask, if there is no obstruction from science and technology, why do you still need to spend so much effort to publicize and protect the environment now? Besides, the current network problem is exactly what everyone is worried about. Many teenagers who should be happy in the motherland have gone astray and embarked on the road of crime. You said that although the internet can facilitate us to find information, how can such a small advantage be compared with the future of the motherland?

In primitive times, human beings only need the resources on the surface of the earth to survive, and only need biological resources such as streams, fruits on trees and grass seeds to entertain themselves. Later, tools appeared, and then breeding was carried out, using resources to break through a foot. Later, coal mines, metals and other resources went down to the seabed of 100 meters, and then down to 5000 meters, and human beings accelerated to ask for resources from the depths of the earth. When humans use core resources,

For example, biosafety is a scientific and technological system for detecting, evaluating, monitoring, preventing and treating biological hazards. It is a new frontier discipline that studies the effects of various biological factors on human health and applies existing theoretical knowledge, technology, engineering design and equipment to prevent people, laboratories and the environment engaged in related work from being harmed by potentially infectious substances and biotoxic substances. Biosafety problems are at least manifested in the following aspects:

The great harm of infectious diseases

Infectious diseases, including human, animal and plant infectious diseases, especially human infectious diseases, are the most important biosafety issues. Infectious diseases are still the leading cause of death in the world. In China, infectious diseases still pose a serious threat to 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 every year in some parts of the country and some countries and regions in the world; In the 20th century, the whole international community made unremitting efforts to ban biological weapons and made some progress. However, in the 2nd/kloc-0th century, the potential threat of biological weapons has greatly increased, and some countries and regions may continue to develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and bioterrorism marked by the "anthrax incident" in the United States poses a real threat to international security. Yuan, 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.

the second

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 die of a great plague. Agree with 0| Comment 20 1-5-3 20: 29 Enthusiastic users.

Scientific development is harmful. Agree 0| Comment 20 1 1-5-3 20:55 ☆ Cool ☆| Level 3

Is the development of science and technology beneficial or harmful (pros and cons)

Moderator: Hello, judges, debaters and audience. Today, the theme of our debate is the development of science and technology: advantages or disadvantages. Society is developing and technology is progressing. Today, we see that the development of science and technology has brought us both benefits and disadvantages. How should we treat such advantages and disadvantages, advantages or disadvantages? Let's ask our debater to give us a wonderful answer.

Positive argument: As for the debate about whether the development of science and technology is beneficial or harmful, friends agree that the advantages of the development of science and technology 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?

There is an argument on the other side: how many amazing changes have taken place in the world since mankind entered the 2 1 century. While people are delighted with the rapid development of science and technology, they have also experienced better anxiety 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 door of hell. The invasion of various viruses, the exhaust gas behind cars, the exhaust gas from factories and so on. Don't invade our beautiful home. Why are our homes threatened, why are trees cut down in large numbers, and why is the air not fresh? These are all kinds of criminal evidence brought by science and technology. Modern science and technology have brought us some comfort and convenience, but at the same time, they have also brought about a wide range of influences. How can human beings live comfortably without a beautiful environment? If people don't remedy their mistakes quickly, mankind will eventually be destroyed by science and technology.

Moderator: OK, we invite both sides to debate and state their views.

There are two kinds of views: the ancient people were superstitious about ghosts and gods, and believed that human life was decided by heaven, and birth, illness and death were controlled by heaven;

In modern times, people have proved that superstition is not desirable through the development of science and technology, and they should create their own lives through their own hands. In ancient times, many people were seriously ill, and doctors could do nothing but watch patients die painfully. But now, through the development of science and technology, most intractable diseases have been successfully cured, and people don't have to worry about getting sick. ..... The above example is just the tip of the iceberg of the case that scientific and technological development benefits mankind. The rapid development of science and technology is unimaginable to ancient people. Why do TV and newspapers talk about promoting the development of science and technology almost every day, because how is the dream of flying for thousands of years round? It is the development of science and technology; What makes communication convenient? It is the development of science and technology; Why can seriously ill people live a happy life again? It is the development of science and technology! If the development of science and technology is wrong, then why do inventors and scientists such as Galileo, Newton, Edison, Madame Curie and Einstein dedicate their precious lives to science? Why spend so much precious time on the "wrong" cause? Have they no judgment? Who thinks their death is worthless, and who thinks their contribution to science is meaningless?

Opposing point of view: the development of science and technology has brought benefits to our lives, which we do not deny. However, we believe that the disadvantages brought by technology outweigh the benefits. First of all, although cars are convenient for us to travel, the exhaust gas from archways has caused environmental pollution and affected human health. Second, the appearance of entertainment facilities such as television has brought convenience to people, but it has also virtually blocked the communication between people, which is weak. There is also the emergence of the Internet. There is no denying that some lawless elements have the opportunity to disrupt people's lives and wait for a series of side effects brought by your so-called high technology. How can you just sit back and watch?

Moderator: Well, both sides have just stated their views, so we will enter the free debate session. There are 3 minutes on each side, please cherish! There is a tripartite debate.

Three arguments: of course, the development of science and technology has also caused some negative effects, but these effects should have been very small, but human beings are like a magnifying glass, magnifying these negative effects. If humans can consciously reuse plastic bags instead of littering them, will it cause such serious white pollution? If mankind can exploit resources exhaustively, will it cause the current shortage of resources? If humans can save water and factories don't illegally discharge pollutants, will it cause serious water shortage now? There are many such things. Some people not only don't introspect, but blindly point the responsibility at "technology". I feel ridiculous and desperate for these people.

The three arguments contradict each other: just now, what the other debater said was just a hypothesis. Please come back to reality and ask, if there is no obstruction from science and technology, why should we promote environmental protection now? Besides, the current network problem is exactly what everyone is worried about. Many teenagers who should be happy in the motherland have gone astray and embarked on the road of crime. You said that although the internet can facilitate us to find information, how can such a small advantage be compared with the future of the motherland?

Four arguments: However, the development of science and technology has more benefits. The launch of the rocket has fulfilled the century-old dream of China people, and the completion of the Bird's Nest Water Cube has fulfilled China's Olympic dream. Without technology, how can China people realize their dreams? Why do you want to grasp the problem of network?

Oppose the other side's four arguments: the other side thinks the network problem is very important. Teenagers are the flowers of the motherland, and the future of the motherland depends on teenagers. The internet has made teenagers confused, and how many teenagers can't extricate themselves from it? If the next generation of the motherland is addicted to the internet, how can they realize more dreams of the motherland? Excuse me, another debater.

A positive statement: 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 life 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?

Contrary: In primitive times, human beings only needed resources on the surface of the earth to survive, and only needed biological resources such as streams, fruits on trees and grass seeds to entertain themselves. Later, tools appeared, and then breeding was carried out, and the resources were utilized to a depth of one foot. Later, coal mines, metals and other resources went down to the seabed of 100 meters, and then down to 5000 meters. When people make use of them, they speed up their quest for resources from the depths of the earth.

Argument: As long as we control science and technology, the earth will not be destroyed.

Moderator: Three minutes. Just now, after fierce competition between the two sides, we should sum up. Now, let's enter the closing meeting. Let me start with four arguments.

Four arguments: Thank you, moderator! Science and technology are the primary productive forces, and high-tech and its industries have promoted the development of the national economy. It can be said that high-tech and its industry have become the locomotive of contemporary scientific and technological development. Science and technology have changed people's ideas, improved people's living standards and promoted the development of socialist civilization. Scientific development can reflect a country's economic development level and national economic literacy. Science and technology are the primary productive forces, the concentrated expression and main symbol of advanced productive forces. I said that to develop productive forces and improve economic benefits, we must first rely on the development of science and technology. From the perspective of productive forces, science and technology can constantly improve and update labor tools, improve the quality of workers and make full use of labor objects. In short, the development of science and technology can greatly liberate productive forces, even create new industrial sectors, and lead to the rapid development of the national economy. We must adhere to the strategy of rejuvenating the country through science and education, so that the economic growth mode can get rid of the extensive old road and turn to the track centered on improving economic efficiency. It is indispensable to pay attention to the quality and benefit of economic development TV 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, we can watch the broadcast at home. A series of technologies have really brought us benefits, so we insist that the development of science and technology has both advantages and disadvantages!

Four arguments against it: in today's society, science is developing rapidly and many high-tech products are constantly emerging. Computers, cars, dishwashers, washing machines ... have entered the lives of ordinary people. They do bring a lot of convenience to our lives, but at the same time they gradually lose the basic abilities of human beings. With computers, people no longer think with their brains, because they can do it with computers; With cars, people are no longer used to walking, walking, but driving for a ride; With the dishwasher, people no longer wash dishes by hand. Maybe one day, people will forget how to wash dishes. The development of science and technology is mixed. Happily, it provides the greatest convenience for our life. What is worrying is that one day computers will replace the human brain and machines will replace the hands. By then, the world will no longer be dominated by people who think they are smart, but machines invented by human beings! So I think: the development of science and technology will inhibit the all-round development of people!

Another example is airplanes, rockets, networks and satellites, which originally appeared for military wars. The same technology is used as an accomplice to the destruction of mankind while benefiting mankind. So we think that the disadvantages of scientific and technological development outweigh the advantages!

Moderator: The debate is over! Both debaters demonstrated their views on the question "whether the development of science and technology is beneficial or harmful". Let me draw a conclusion. The development of science and technology has indeed brought convenience to mankind, but at the same time, we should also deal with all kinds of problems arising from it to make our earth, the home of mankind, more beautiful. Let's work together and agree with 0| comment 2011-5-418: 40.

Lida agrees with 0| Comment 2011-5-418: 57 Lan Ruo | Level 1.

On the one hand, technological development has great advantages; on the other hand, technological development has great disadvantages.

In the debate

Moderator: As we all know, the development of science and technology has brought great convenience to human life, such as air conditioners, cars and mobile phones. But at the same time, the development of science and technology also has disadvantages, such as cell phone radiation and air pollution. Today, we are debating whether the development of science and technology is beneficial or harmful. Then, the debate begins now, please let the debater speak!

Founder (debate): With the development of science and technology, great changes have taken place in our lives. The former carriage has become the present car, and the oil lamp has become the electric light ... Now, if you want to send a blessing to a foreign friend, you don't need to send it by long mail, you just need to click an email and send it in less than 3 seconds. Telephone and mobile phone also bring convenience to our communication. Is that so? Please answer the opposing debater.

Counterparty (debate): That's true. However, as we all know, technology has also brought an impact on human health. Cell phone radiation makes many people sick. Industrial wastewater pollutes the original clear rivers, and animals living in these rivers in the past will get sick or even die after drinking this water ... Isn't this the disadvantage brought by the development of science and technology?

Pro (Second Debate) (loudly): Please don't digress. This is a debate about the advantages and disadvantages of technological development, not the disadvantages of technological development! Although the situation described by the opposing debater does exist, technology can't stop the pace of progress! It is very hot in summer, and the appearance of air conditioning has solved this problem. When the sun is blazing outside, we hide in the house and enjoy the cool air of the air conditioner. Isn't this the advantage brought by technology? We don't blow air conditioners indoors. Do you have outdoor fans? (Laughter)
