Advantages and disadvantages of science and technology 1 With the development of science and technology, people's lives are more comfortable, but the environment and health are getting worse. I think that scientific and technological progress does more harm than good.
The advantage of scientific and technological progress is that it provides a convenient way of life for human beings. For example, "knowing the world with one click", the knowledge on the computer is very comprehensive. On Baidu, you can find the information you want to check. In my spare time, I can also play games online and watch some movies. You don't have to go online, and the things you sell are particularly cheap. Cars have always been human means of transportation. With it, we can run much faster than running, and can also be used as a tool to catch time when we are about to be late. Nowadays, technology enriches life and makes human beings more comfortable. In hot summer, every household has air conditioning. How cool it is to blow the wind on a hot day! A cool breeze is blowing, and it's almost winter.
It is precisely because of scientific and technological progress that the environment is being polluted day by day. The car is driving, the air conditioner is blowing, you are comfortable, but Mother Earth is crying. Cars emit a lot of exhaust gas, which makes the carbon dioxide in the atmosphere rise sharply, the atmosphere is seriously damaged, sour language becomes a "green killer" and the first line of defense of the earth is broken. Air conditioning releases heat every day, causing the greenhouse effect, which makes the two glaciers in the North and South poles melt at an unprecedented speed and the sea level gradually rises. At this rate, the earth will become the sea of Wang Yang sooner or later. Humans cut down trees frequently, and the earth turns yellow day by day. Drought, soil erosion and sandstorm have seriously affected the normal survival of human beings. Computers have been damaging people's health. In your happy play, the computer really damaged your eyesight unconsciously. Cheated people commit suicide frequently, and countless people commit crimes because of computers. Science and technology, like a double-edged sword, is helping mankind while destroying it.
Science and technology do more harm than good. In order to live a better life, we must improve our living environment. Only if it is harmless can it help mankind.
Advantages and disadvantages of scientific and technological composition 2 Just after the rainstorm last night, there was another heated debate this morning.
At first, the third debate was crowded, and soon, the indoor staff entered the debate state. Like the previous debates, the rules and methods are the same, but the topic of this debate is: scientific and technological development: benefiting the big? What are the disadvantages? But this time the host, Mr. Chen, appointed several debaters.
It's easy for the debater to take the lead, just say whether he thinks it's good or not. However, the more difficult it is, everyone is calm and gentle at first, but in the end, there is a faint smell of gunpowder. The classmates across the street are really fierce. No sooner had the positive students thrown out an idea than they caught it. Students who are against it think that the development of science and technology has affected human environment and health. But the students in the square believe that science and technology are constantly developing and progressing, and people's living standards are constantly improving in the beautiful environment brought by high technology. The students in the square not only put facts, but also make sense. Both sides presented their evidence in time, and finally, the debate became more intense.
In the first few rounds, my deskmate played several rounds with my information. Later, the small universe broke out and caught several rounds. Moreover, he also put forward a very innovative point of view: the development of science and technology has also affected the healthy life of mankind. For example, some unscrupulous merchants cheat the elderly through WeChat and other networks and sell fake and shoddy goods to the elderly, thus defrauding the elderly of their money, resulting in many elderly people not only losing money, but also affecting their health and aggravating their illness because of eating fake and shoddy products. So the development of science and technology is harmful!
At this point, the positive side is not to be outdone, and immediately refutes him: if the elderly are guided, then they will raise their awareness of prevention and will not be easily deceived. Step by step: not only should we raise the awareness of prevention of the elderly, strengthen correct publicity, but also do a good job in source supervision. What is the source? Is the person who uses technology! If someone cheats, he will be punished by law. At this time, the gunpowder theater has just begun to stage! Double opposition is firm and refutes each other.
Debate, debate, some students who usually don't talk can't help but throw themselves into the debate. With applause and cheers, the debate is coming to an end in the gunpowder theater.
In fact, technology is like a double-edged sword, which has both advantages and disadvantages. We should not only learn to look at the pros and cons of scientific and technological development objectively, but also understand that only by correctly controlling and controlling human beings, learning to seek advantages and avoid disadvantages, and fostering strengths and avoiding weaknesses, can science and technology better benefit mankind.
Advantages and disadvantages of scientific composition 3 In my life, I think the development of science and technology is of great benefit to us. At the same time, with the development of science and technology, environmental pollution is on the rise, which will also bring many disadvantages to mankind.
For example, in our life, scientific and technological progress is good, but it also increases environmental pollution, sometimes not only a little pollution, but even a lot of pollution. There are many examples in life, let's give a few simple examples! First of all, the most obvious thing is that car! Although the car is a very convenient means of transportation. However, because the number of cars is increasing greatly, a lot of exhaust gas will pollute our air, and most of our sky is surrounded by air pollution. It is rare to see blue sky, long white clouds and stars at night. Now, there are few stars in the sky, not as many as a few years ago. The stars in the past are all over the sky, countless. But what about now? Hardly, only occasionally I see two or three little stars shining faintly, as if their life is coming to an end, which makes people feel distressed. Compared with before, isn't it all caused by the development of science and technology? Without cars, chimneys and garbage, how can we not see the blue sky, the long white clouds and the twinkling stars in the starry sky every day? So I think the development of science and technology is harmful, although many people think it is beneficial, but if our science and technology develops to a high level, I'm afraid the earth will perish. So I want people to study how to turn cars into solar cars, so I won't feel that the development of science and technology is harmful. I hope those technicians can correct it.
The development of science and technology has brought us advantages and disadvantages, but we should correct these disadvantages.
Advantages and disadvantages of scientific composition 4 Throughout the history of scientific development for thousands of years, science and technology have made great progress than before. We live in an era where technology is changing with each passing day, and we have already felt the convenience brought by technology. Indeed, technology has brought us many benefits, but it has also brought us many disadvantages.
profit
The development of science and technology has brought a lot of convenience and speed. Sitting at home with a little mouse, you can communicate face to face with your relatives who are far away from home. When traveling, hold the steering wheel tightly, and you can travel all over the country and enjoy the scenery; When you live in a hotel, press the remote control of the air conditioner leisurely, and you will enjoy the happiness of cold and warm. All this is brought to us by technology. Of course, technology has also increased our average life expectancy by more than 30 years. As far as China is concerned, if a person can live 30 years longer than before, the extra years of 654.38+300 million people add up to 39 billion years, which is equivalent to living three years more in a century. 900 million centuries, not to mention that this is only a part of the earth. If you count all mankind, the number will be even bigger. In short, science and technology have brought us happiness today. Computers, televisions, air conditioners, automobiles, cotton trousers and hybrid rice have brought us too much convenience and made great progress in human development.
shortcomings
Technology does bring a lot of convenience, but it also brings a lot of disadvantages. Take the nuclear warhead invented by Einstein as an example. Although the nuclear warhead is the result of the development of human science and technology, it has brought many sacrifices, and many people died in the smoke of the nuclear warhead. Of course, the disadvantages of technology go far beyond this. The invention of cars, trains and airplanes produced a lot of toxic gases, which caused great damage to the environment. These inventions mean that human beings no longer rely on feet, but nature must have given us feet for a purpose. With these high technologies, what is the use of nature for our feet? According to statistics, in 20xx, oil will be exhausted, the atmosphere will be destroyed and water will be polluted, all of which are brought by science and technology!
Generally speaking, the advantages and disadvantages of science and technology are for the survival of mankind.
Advantages and disadvantages of scientific and technological composition 5 With the development of human society, we have entered an era full of high technology, which makes our life full of freshness and makes our era stand at a new starting point.
However, the sky now seems to be covered with a layer of yarn. It is not as blue as it was decades ago, and the river is so greasy. Garbage and dead fish and shrimp are also common on the river. The forest area has decreased sharply, but there are more and more barren yellow land, and sandstorms are more rampant in northwest China. What caused all this? Is the earth really doomed to destruction?
We can't deny that the benefits brought by scientific and technological development are everywhere. In ancient times, fighting was a common thing. Those soldiers who were seriously injured in the battle can't wait for the day when they see their loved ones, because there is often only a dead end waiting for them. Now, if there is a car accident or other personal injury, as long as we make a phone call in time, the ambulance will arrive immediately and take you to the hospital for emergency treatment. If it had been so timely, so many people would not have died in ancient times.
While science and technology bring us benefits, problems also follow. Now countries have gradually invented nuclear weapons and chemical and biological weapons, and these terrible weapons and equipment have also been applied to a certain extent in the two world wars. Although they upgraded the people's military equipment, human life was more threatened. If these two world wars had happened in ancient times, the death toll would never have been so shocking. The most terrible thing is that at the end of World War II, the United States dropped two atomic bombs on Japan, "Little Boy" and "Fat Man", which almost razed Hiroshima and Nagasaki. For a long time, there were no normal plants growing there. Moreover, in the decades after that, all kinds of viruses flooded in this area, almost all newborns were suffering from various strange diseases, and almost no healthy people appeared there. Until now, it is difficult to grow there.
Everything has two sides, so does science and technology. We should not only learn to look at the pros and cons of scientific and technological development objectively and dialectically, but also understand that only by learning to seek advantages and avoid disadvantages and correctly grasping and controlling the development of the situation can science and technology exert its greatest value.
Advantages and disadvantages of scientific composition 6 With the development of modern biotechnology, our life is getting better and better, and technology is becoming more and more developed, but there are also some disadvantages. Today, the teacher asked us to have a debate on the advantages and disadvantages of scientific and technological development, but I still feel that the advantages outweigh the disadvantages, so I became the favorable (positive) party, and the teacher was the referee.
The debate officially began. First of all, our Zhang You said, "The more advanced modern technology is, the better life will be. We can eat modern excellent rice and have car lights. " Opponent Guo Runfang stood up and said; "However, some wastewater and sewage are now discharged into farmland, and some rice is polluted; Cars and electric lights need very special materials, so a lot of mineral products in our country are wasted. " Our Xu Hanlin said: "With the development of science and technology, the rice we eat is sold in the market after safety inspection, which ensures people's food safety;" Moreover, with modern papermaking, we can learn the knowledge in books better. "Rival Zhu Dongge stood up and said," Now everyone is wasting paper and always throwing it around. Now, because of the paper-making technology and everyone's waste, it is simply destroying the forest! "And now the weather is getting warmer, the sea level is rising, and Japan is almost submerged!" Cao said to him, "Don't think of Japan. Now scientists are trying to remedy it. The previous Sunshine Youth Daily also said that the whole country will spend hundreds of millions to freeze the Antarctic and Arctic, pump seawater into the air, and then turn it into snowflakes by machines. Although it takes some time, it is better than letting it melt! " Then in class, you tell me everything, and everyone quarrels about it. At this moment, the teacher came in and said, "Quiet, quiet". There is no winning or losing in this debate, and there are advantages and disadvantages. We can only wait for you to study hard and create higher technology for our society in the future and earn more profits!
In this debate, the students were very angry and nervous, but there was no winner, so we should study hard in the future and invent more products in the future, just as the teacher said.
Advantages and disadvantages of scientific and technological composition 7 Is the development of science and technology beneficial or harmful? Many people can't give a real answer.
If the world remains the same, it will be very inconvenient for people to travel. People may still live in that primitive life, and some diseases can't be cured, so we can only watch those people die. People will become more and more ignorant. Now that technology is developed, people bid farewell to the life of eating animals and drinking blood. Many diseases can be cured and people's health can be guaranteed. Life is also more colorful: TV can let people know many things, and telephone can let two friends who are far away get in touch. With the advent of the Internet, many people can watch a lot of news, read books and study at home. There are also online shopping centers such as Taobao and Tmall on the computer, so that people can buy many good things without going out. Now many schools have set up information rooms for students and teachers to consult a lot of materials to help students learn by going up a flight of stairs. So the advantages outweigh the disadvantages.
But some people catch and kill small animals indiscriminately for money. The waste water, waste gas and waste residue discharged from chemical plants have seriously polluted water resources, forest resources and atmospheric resources, and destroyed the natural environment. Although the appearance of cars facilitates our travel, the exhaust gas from archway has caused environmental pollution and affected our health. The appearance of entertainment facilities such as television brings convenience to people, but it also virtually blocks the communication between people; What's more, the emergence of the Internet has given some lawless elements the opportunity to disrupt people's lives, and also let some young people who study well fall into the network trap. People are used to catching food and avoiding wild animals, and gradually form a strong body. Now, children live a carefree life with clothes to reach out and food to open their mouths. Children gradually become lazy and weak. It can be seen that the disadvantages outweigh the advantages.
The development of science and technology has both advantages and disadvantages. As long as we care for the environment and don't indulge in the internet, the advantages will definitely outweigh the disadvantages!
Advantages and disadvantages of scientific and technological composition 8 With the progress of science and technology, our life is inseparable from science and technology. Such as a smart phone or a computer. They have influenced our lives. They are everywhere and we can't live without them. But it's all good, okay? No, I don't think so.
Xiao Ming, a fifteen-year-old student. He has a habit of looking for a mobile phone whenever he encounters a problem, and then looking for an answer. This helped him shorten the time for doing his homework. However, he still doesn't understand why these problems are solved in this way. This is what the saying goes, you know but you don't know why. On Sunday, he is doing his homework. Then someone invited him to play football. So, Xiao Ming wants to play with them. Do nothing about homework. Not only many, but also difficult. It really made Xiao Ming waste a lot of brains. So, he has a plan in mind. I decided to pick up my mobile phone, open my homework help and start shooting questions. In a short time, all the problems inside were solved by him. So Xiaoming happily went out to play football with his friends. But does Xiao Ming really understand how to do these questions? Absolutely not, absolutely not. Although Xiaoming has finished these homework, the original intention of homework is to consolidate knowledge and deepen understanding. Small to do this is just to deceive yourself in action. He said that he did it, but the original intention of the homework was not achieved. I really don't agree with Xiao Ming's practice. The answer comes too easily, and the answer comes too quickly. This is the inevitable result of scientific and technological progress. I think we should stay away from this phenomenon. It's normal to have no problems. Then we looked up the questions on the mobile phone and found that we could do it, which was naturally good for everyone. However, many people do not do this.
Technology is a double-edged sword. I hope to make good use of its good side and try to avoid the bad side. This is the best way to use.
Advantages and disadvantages of scientific and technological composition 9 Compared with ancient life, today's life is very different, and this world difference lies in the development of science and technology. Throughout the ages, which dynasty did not attach importance to the development of science and technology? Look back at the four inventions monopolizing the glans penis; Look at the astronomical calendar and marvel; Visit Zhao Zhouqiao, Compendium of Materia Medica with exquisite patterns, Oriental Canon; Look at the value of pi, the Silk Road, and develop the economy. Blue and white porcelain is famous all over the world. The development of science and technology is the road to national strength and a driving force of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a rich material life? How can we eat hybrid rice without the progress of science and technology? How can I put on cotton-padded jacket? I didn't. So you live in a tall building?
Nowadays, people prove that superstition is not desirable through high 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 it's different now. With the development of science and technology, most intractable diseases have been successfully cured, and people don't have to worry about getting sick ... China is one of the four ancient civilizations, and invented papermaking, printing, gunpowder and compass. People have been advocating the development of science and technology since ancient times. Without the development of science and technology, can we still tell the direction when we get lost? Without these scientific and technological developments, we can only stay at the stage of engraving on branches or animal bones.
On a larger scale, the Soviet Union invented a manned spacecraft at 196 1 and successfully flew it, while China launched an unmanned test spacecraft at 1999, with a difference of 38 years. If China had developed science and technology before, then Eight-Nation Alliance would not have invaded China. It was precisely because we in China were backward and underdeveloped in science and technology that other countries joined forces to bully us in China! Science and technology are underdeveloped, that is, the world has no status and has been bullied!
Science and technology have changed history, yes, without the development of science and technology, we would not have a happy life today; We should fear it with awe. How can we say that the development of science and technology is full of drawbacks?
Science and technology change history, knowledge changes destiny!
Advantages and disadvantages of scientific composition 10 In a classroom, the preparatory bell rang. The students returned to their seats, excitedly looking forward to what would happen next.
Under the nervous gaze of the students, the "judge" on the stage gave an order: "Pull the table." Suddenly, the whole class turned into a train, with rows of tables left and right apart and no one in the middle of the classroom. Everyone put the data collected yesterday on the table, and everyone jumped to try.
"One or two groups are positive, and three or four groups are negative. Now choose four debaters. " The judge began to argue. Those who are selected will make a happy "yeah" sound, and those who are not selected will sigh.
The long-awaited debate began. First of all, the positive argument puts forward the viewpoint: "I think if there is no scientific and technological development, then we are no different from primitive people."
"Stop, stop!" The "judge" said, "State your opinion!"
After some arguments, I suddenly realized: "I think the advantages of technological development outweigh the disadvantages."
Now, the opponent will argue and state his point: "I think the development of science and technology does more harm than good, because the development of science and technology pollutes the environment."
Now, let's give an example: "The launch of satellites enables people to predict the future weather, so the advantages of the development of science and technology outweigh the disadvantages."
Then the opponent retorted: "The development of science and technology consumes a lot of resources and causes environmental pollution, so the disadvantages outweigh the advantages." The second debate continued Huang Xinran's point of view.
All three parties in the argument stick to their own views. Everyone looked at Sanbian, expecting his retort: "There is nothing perfect in the world, technology."
From debaters to free debates, to exchanging views and refuting each other, the debate is very intense. Finally, four students also won the title of "the best debater". The debate ended with the teacher's calm and clear summary.
Through this debate, do the advantages of scientific and technological development outweigh the disadvantages? Or do more harm than good? Most students have a deep understanding that everything has two sides, and technology is like a double-edged sword, with both advantages and disadvantages. We should not only learn to look at the pros and cons of scientific and technological development objectively and dialectically, but also understand that only by correctly controlling and mastering, learning to seek advantages and avoid disadvantages, and fostering strengths and avoiding weaknesses, can science and technology better benefit mankind.
After a debate, I experienced a journey of speculative collision. In the debate, everyone's understanding of the development of science and technology gradually turned to a clear understanding of the "challenge" competition, regardless of the outcome.
