Changes brought about by the development of science and technology

I once heard my grandfather say that as far back as hundreds of years of history, society was a farming society that relied on heaven to feed. At that time, there were no electric lights, no TV, no car, and they ate leaves and bark, even belts. Now I have heard from my mother that when she was young, she went to study in the morning and evening. Everyone brought a kerosene lamp, not even a stationery box. They used a paper box as a stationery box, and they ate pickles every day. Every time you visit or celebrate your birthday, you eat white flour buns. Planting crops is carried by people on their shoulders, and ploughing is by cattle and horses. Every child only adds one new dress a year. New clothes are not worn until the New Year. Adults do not even add one new dress a year. By the 1980s, Deng Xiaoping had proposed four modernizations, and the land had been heavily contracted. The people's living conditions were improved. They stopped eating Wowotou, put on a white mask, and lived in a new tile house. In the twentieth century, eating was about nutrition, clothes were about being famous, farmers were living in high-rises, urban people were living in villas, and driving cars. Families in rural areas also bought refrigerators, color TVs, and washing machines. Everyone used mobile phones and drove motorcycles. In the 21st century, China has landed on the moon, opened high-speed trains, ocean-going ships, and so on. The number of new technologies is also innumerable. Looking at the past, Bibi now, we live in a very comfortable living environment and don't worry about spending money on food and clothing. We must study hard and serve the motherland when we grow up.


Changes brought about by the development of science and technology

Today, the teacher arranged an essay. The requirements are: read the text taught today to my father or mother, ask them to talk about the changes brought about by the development of science and technology, and then write down their words. In the evening, when Dad came back, I ca n’t wait to ask: Dad, please tell me, what changes have technology brought to us? Dad said: The modern science and technology department can be developed, and the invention of water heaters and electric lights has added convenience to our lives. I was puzzled and asked: Dad, how did you live at that time? Dad replied: At that time, we could only use coal to boil water and use matches to light, not as comfortable as now, water heaters, electric lights. I broke the casserole and asked: Dad, how did you harvest and eat? Dad said: The harvesting tool was a sickle, but now the harvester is beeping. The farmer sits on the harvester with a smile on his face, like a blooming flower. These high technologies have brought farmers the joy of harvest and unlimited hope, and the development of these technologies has brought surprises to our lives.

what! Today, with the development of science and technology, our lives are getting better and better. I believe that through our continuous efforts, our lives will be icing on the cake!

Changes brought about by the development of science and technology

Today, I will introduce the development of computers. A computer, also called an electronic computer, was invented by American Von Neumann in February 1946.

At first, the computer needed a room to hold it, and several people needed to operate it together. At that time, the computer was very slow, and it took a long time to calculate a mathematical formula.

However, due to the advancement of technology, the computer has become a pure screen computer, and the speed has become faster, but the size has become smaller, and one person can operate and move it! The most important thing is that the computer has more and more functions.

With the continuous efforts of scientists, the pure-screen computer has become an LCD computer. The computer screen is very thin, with little radiation, and the screen is much clearer.

Under the research of scientists, the LCD computer has become a laptop computer, which has more functions, can be carried around, and can communicate with people around the world on the train.

This is the process of computer development! This is the change brought about by the development of science and technology!

Talk about the advantages and disadvantages of technological development

As the bell rang, the teacher entered the classroom, and a fierce and wonderful debate kicked off.

The debate just started, and it was convenient to launch an attack on the opposition: in ancient society, people could only drink blood, and now look at how we live, what we live, how can we live so comfortably without scientific development? It turned out that a bit of cold and fever can kill a person, and now medicine can reach the point of coming back to life. It turned out that people were rare in the seventies, but it is not unusual to live to be one hundred years old. Cars and airplanes, trains and ships were unimaginable in ancient times. A few kilometers of road is an expedition. Now, the earth is like a small village, which can be turned around at any time.

The opponents did not want to be outdone and immediately retorted: In today's society, cars are everywhere, not only causing great harm to people's physical and mental health, but also causing pollution to the atmosphere. All living beings in the world are harmed by this kind of technology products to a certain extent. It is selfish for human beings to disregard the safety of other earth creatures for their own convenience. Taking a step back, cars are also very harmful to humans. Freons in air conditioners and refrigerators also destroy our precious atmosphere. So-called high-tech products have made the world dirty and rigid. The free land was devoured by human beings; the free sky was narrowed by human beings; and the free sea was also occupied by human beings.

Now Ma Wei is a bit cruel! Let the square get stuck for a while. At this very moment, a voice emerged: scientific development has brought people into the era of reason, and people no longer blindly superstitious, but to pursue the truth. Without scientific development, we thought that heaven would be a perfect place; without scientific development, we thought that heaven would be heaven and underground would be hell. Science gives us a better understanding of where we are. As soon as the language fell, everyone's eyes shot towards him. The classmates cheered warmly, the anti-party shouted out loud: Traitor! traitor! I did not expect that there will be traitors in the 21st century. It is unheard of, never seen!

In order not to be outdone, the opposition quickly retorted and wanted to suppress the square of the flames: In fact, the entire international community has made unremitting efforts to ban biological weapons and made some progress. However, in the 21st century, the potential dangers of biological weapons have greatly increased. Some countries and regions may continue to develop and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons. The biological terror marked by the anthrax incident has already posed a real threat to international security.

Began to summarize the submission.

In the future, the earth will be destroyed in the hands of people, and everything on earth and human beings will be destroyed. In the future, humans can live to more than two hundred years old, and we can run freely in the solar system and even the galaxy. In the future, do we have a future? In the future, our future will be better? Each country has its own myth, how beautiful it is; each country has its own famous works, which have been passed down to the present day; each country has left the classic famous paintings, how precious they are. And scientific development turns everything into history. There is no longer a beautiful myth in fate, because there is reality; there will never be a good name, because there is no romance. ; There will never be a famous painting, because the city is no longer a landscape. In ancient times, when people looked at the moon, they thought of Chang'e, they thought of Yutu, and their relatives and friends in the distance. Now, facing the equally bright moon, people think of a planet full of holes and whether it can live on it. The society is constantly developing and progressing, and science and technology continue to leapfrog and innovate for the benefit and harm of humankind. Science will always be a double-edged sword, providing convenience to human beings, and it will certainly make humanity pay the most precious things. Facts have proved that the emergence of such modern tools not only proves that it is inseparable from the exchanges in different regions of the world. It seems to be an impetus for the acceleration of social development. It has woven a chain around the world with a chain of chains, covering development and life. Today, the two sides are evenly matched, regardless of

With the end of the bell, the debate will end in a draw!

Essays on technology: I think the disadvantages of science and technology development are more than 200 words

I think the disadvantages of technological development outweigh the benefits.

During the development of science and technology, garbage will inevitably be produced, which will bring white pollution, which cannot be decomposed and bring environmental pollution to the city. If the garbage is buried in the soil, waste plastic products will continue to accumulate in the soil, which will affect the absorption of nutrients and moisture by the crops, leading to reduced crop yields. . Last year, there were 20 herdsmen near the Qinghai Lake with a total of nearly 1,000 sheep, and the economic loss was about 300,000 yuan due to swallowing waste plastic products as food.

Not only in terms of environment and agriculture, technology has brought disadvantages to people, but in other incidents, it has also caused more casualties. In the Second World War, in order to force Japan to surrender quickly, at 8:15 on August 6, 1945, Hiroshima City dropped a uranium bomb coded as a little boy, causing 24.5 million people in Hiroshima City. 200,000 people were injured and injured, and the entire city was turned into ruins. How terrible!

Therefore, I think that the disadvantages outweigh the advantages in the development of science and technology.

Modern technology brings harm to the composition of 350 words

With the development of modern technology, people generally use high technology, and modern technology is gradually affecting people's lives. If there is no television, the new policy issued by the central government will not reach thousands of households quickly; if there is no computer, people who study abroad will not be able to video chat with their families; if there is no modern technology, people's living standards will not be greatly improved Maybe now we are still living in a time when information is closed. But modern technology also brings harm to the environment and human beings.

Recently, people have become rich, and they are too lazy to walk, and use cars instead of feet. But cars do far more harm than we think. Although the exhaust gas emitted by a car does not seem to be much, its pollution is very large, and we hundreds of millions of people around the world buy cars, and some people also buy several cars, so its harm cannot be estimated. As a result, the sky is not as blue as before, and the world is warming.

Computers are also harmful to human beings, although computers can give us a lot of new knowledge and know something that we never know again. But because of computers, many people have become otakus. The radiation emitted by the computer can not be ignored. Every year, many children wear the bottom of the wine bottle because they spend too much time playing the computer. Makes the distance between people more and more.

Although modern technology is very convenient, it is very harmful to people and the environment. We must use them as little as possible and do things within our power to make the world a better place.
