Prologue:

With the development of science and technology, human civilization has taken another big step forward, from the previous carriage to the car, from the previous oil lamp to the electric light ...

Now, people's lives have become better. Telephone speeds up communication, cars and motorcycles speed up the pace of life, and rice cookers and gas are used to cook delicious meals ...

TV 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 mascot of the Olympic Games is announced, you can watch the broadcast at home. Computers are more widely used in all walks of life. When we send a letter to Brazil in Haining, it only takes a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world on the Internet. You can read news, watch movies and listen to music online. You can listen to the teacher's class, find information, and do shopping, medical treatment and first aid at home ...

Need to refute:

On the contrary, environmental pollution is the most direct and conspicuous disadvantage.

If you can't say this, take plastic bags for example! It's not that our technology is too advanced, but that our technology is not. If we can, we will not use plastic bags, but invent low-cost and environmentally-friendly shopping bags. Because of this, we should develop environmental protection technology. Without science and technology, how can the annual flood be controlled, or can we learn from Dayu and dig canals with a lot of people? Besides, Dayu also said, "Man struggles upwards, but water flows downwards." We should keep pace with the times, shouldn't we? Besides, isn't there any relationship between environmental pollution and population expansion? In fact, environmental pollution is caused by human use and technology, but now all the responsibilities are pushed to technology. Is it a little shameful? Grandpa Deng Xiaoping once said, "Science and technology are the primary productive forces." What do you think of this?

Counterparty: species extinction is accelerating. This is caused by environmental pollution and human killing. It also belongs to the disadvantages of scientific and technological development.

In that case, kitchen knives will hurt people, so we don't need kitchen knives. Let's learn karate to cut vegetables! The indiscriminate killing of human beings has nothing to do with science and technology, but the human greed is to blame. After all, guns don't kill animals by themselves. You can't blame everything on technology. Just want to compare the carrier to a horse, people are coachmen, and the carriage behind them is loaded with goods, that is, technology. If the horse goes in the wrong direction, that is, people develop science and technology in a bad direction, will the coachman beat the horse with his whip or play science and technology? This is a simple example, but it shows that the quality of the environment is not related to technology, but to where human beings use technology. It is a double-edged sword, on the one hand, it can smash ignorance and backwardness, on the other hand, it may bring endless disasters to mankind. It's good for you to do good, but if you do bad, the result will not be the same. Besides, if there is no hybrid rice, everyone will eat bark for half a year. Without penicillin, everyone will get tuberculosis? Is the development of science and technology bound to destroy the environment?

Counterparty: What about the panda?

Darwin once said, "The survival of the fittest is the law of nature." However, the reproductive ability of pandas is weaker than that of other animals, and the picky about food and the habit of living alone make pandas on the verge of extinction. Look at people's cockroaches. Even if the atomic bomb explodes, aren't the cockroaches there still "running well-off"? Besides, science can also help pandas, heal their wounds and deliver babies. How nice!

the opposing side: personal safety is becoming more and more insecure. Now tens of thousands of crimes occur every day on average. Most of the criminal means are related to the new technology. Especially, gun crimes are hard for ordinary people to prevent. 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.

your. In the past, due to the corruption and incompetence of the Qing government, we closed our doors to the outside world. China's scientific, technological and military development lags far behind that of the West. Other people's guns are loud, with large caliber, and warships are strong and resistant to detonation. Just when others were eyeing up to invade us, we in China still took spears and shields. As a result, the Boxer Rebellion lost to Eight-Nation Alliance. This is a bloody lesson from history. Although we don't respect war, as a powerful country in the world, we should have excellent military science and technology and lay a good foundation for national defense. Isn't it?

the opposite side: the physical quality of human beings is not as good as before. With the development of science and technology, the appearance of cars, trains, planes and other means of transportation has greatly changed human daily life, and human beings are no longer always dependent on their own legs. Therefore, the physical quality of human beings can't be compared with that of the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers" again. If this situation continues to develop, it may shrink people's limbs and make human beings appear a new form.

Hey, tell you what, even if you invite Xiang Yu from ancient times, he is unlikely to enter the top ten weightlifting in the Olympic Games. Because the Olympic Games is also a technological contest between countries. When the weight exceeds the human limit, we have to rely on technology to help. During training, the coach will show the athletes videos, analyze with him which muscle to use in lifting, pulling, wrist-twisting and clean and jerk, and what height to lift, and then strengthen the training of muscles. It all needs technology. Besides, technology is to bring convenience to mankind. Four students from the opposing side, I ask you, which one of you goes out on two legs and walks home all the time after school? Don't you use transportation as well? In fact, Xiang Yu's poems are only used to express his ambition, and there are exaggerated techniques. Do you really believe that Xiang Yu can pull up the mountain?

On the contrary: various 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 viruses, so that the development speed of science and technology has failed to keep up with the mutation speed of viruses. Maybe one day mankind will die of a major plague.

That's because human science and technology can't keep up. If we keep up, we can develop more drugs to kill germs. Please don't focus on the disadvantages of science and technology. Everyone living on the earth enjoys the achievements of science and technology all the time. Including four students from the opposing side, I believe that all the materials you have to refute us are from the internet or newspapers, which is also technology. Speaking with your own conscience, do you really think that technology should not appear on the earth?

conclusion:

14:28 on May 2, 2118, I believe everyone is familiar with this time. At that time, an earthquake measuring 8.1 on the Richter scale struck Wenchuan County, Sichuan Province, and everyone knows the story behind it. But let's think about it, what sent the liberation officers and soldiers to the disaster area by water? What sent relief supplies to the disaster area by airdrop? What was the first time to get through the road to Wenchuan? What helps people saw through steel bars and dig out the injured? What helped the doctor pull the rescued wounded back from the dying line? -assault boats, helicopters, excavators, chainsaws and medical equipment. This is the power of science and technology! We should continue to develop science and technology and build houses that can resist earthquakes, so that more people can survive. This natural disaster has strengthened our view that the development of science and technology will benefit the future!
