Benefits of scientific and technological development:
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?
Q: Is the development of science and technology beneficial or harmful? 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? 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. Man is small and fragile. He has no huge body, no strength like an ox, and no hard shell like a turtle. However, God has given mankind a clever brain and a pair of hard-working hands. Instead of enjoying success, human beings have chosen to make continuous progress and stand at the top of today's food chain.
Let's compare today's life with that of 10 million years ago, and we are supreme; Comparing today with thousands of years ago, we are condescending; Comparing today with hundreds of years ago, we are happy and comfortable; Comparing today with tomorrow, the future is bright. For thousands of years, it has changed from a carriage to a car, train and plane; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat and mouse know everything about the world.
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 lives 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?
Therefore, science and technology change history, and we don't need to question whether the development of science and technology is beneficial or harmful, because it is beneficial! Rita! Rita! You said that the development of science and technology has brought air pollution, you said that the development of science and technology has produced white garbage, and you said that the development of science and technology has caused the warming of the temperature ... Everything can't be perfect, and the darker the shadow behind the brighter place, but on this basis, you can draw the conclusion that the disadvantages of science and technology development outweigh the advantages? 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, that is, to benefit greatly. This is the only answer to this argument! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth. 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, no and no, because technology is closely related to you and inseparable from you! Now if you write to the chairman and suggest stopping all scientific research activities, will everyone send you flowers or the board of directors shoot you exclusively?
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!

Economic development factors
The process of a country getting rid of poverty and backwardness and moving towards the modernization of economic and social life is called economic development. Economic development means not only the expansion of the national economy, but also the improvement of the quality of economic and social life. Therefore, economic development is not only simple economic growth, but also more extensive than economic growth. As far as the contemporary economy is concerned, the meaning of development is quite rich and complex. Development is always used interchangeably with development, industrialization, modernization and growth. Generally speaking, economic development includes three meanings: 1. The growth of economic quantity, that is, the increase of products and services in a country or region, constitutes the material basis of economic development; 2. Improvement and optimization of economic structure, that is, changes in economic structure such as technological structure, industrial structure, income distribution structure, consumption structure and population structure of a country or region; 3. The improvement of economic quality means the improvement of economic benefits, economic stability, health status, natural environment and ecological balance of a country and region, and the process of political, cultural and human modernization.
In this part, the factors of economic development are edited.
The sustainable development of environment and economy means that economic development cannot be at the expense of damaging the environment. Sustainable development requires that the development of one country or region should not affect the development of other countries or regions. Sustainability means maintaining the natural resource base of human well-being and making the ecological environment develop in harmony with economy and society. Economic growth depends on science and technology as the only productive force, and the innovation and invention of science and technology is the foundation of economic development. 1992 at the second national academic conference on sociology of science held by Nankai university, Ceng Bangzhe proposed that it is scientific and technological productivity that creates wealth, but trade cannot bring wealth growth or transfer; Moreover, the transfer of wealth is from low-tech to high-tech industries. The wealth growth of economic development is reflected in the gross national product, and the distribution and efficiency of cost and time in circulation, management and service directly affect the quality and efficiency of production; Therefore, the more streamlined, clean and efficient management, service and circulation are, the more economic development can be promoted.

Someone said to the host, "if you had listened to that gentleman, you wouldn't have to prepare a banquet today, and there would be no fire damage." It is very strange now that the person who gave you advice is not grateful, but the person who put out the fire is a guest! " The host suddenly realized that he quickly invited the guest who had given the suggestion to have a drink.
Management experience: Generally speaking, people who can settle or solve various thorny problems in the business process are excellent managers. In fact, this is debatable. As the saying goes, "prevention is more important than cure", which can prevent problems before they happen, and it is better to deal with chaos after they become problems. From this perspective, the prevention of business problems is actually better than the solution of business problems.
Sixth, save lives.
In a fierce battle, the captain suddenly found an enemy plane swooping down to the position. As usual, don't hesitate to lie down when you find the enemy plane diving. But the captain didn't lie down at once. He found a little soldier still standing four or five meters away from him. He didn't think much, and a diving fly pressed the little soldier tightly under him. At this time, there was a loud noise, and the splashing soil fell on them. The captain patted the dust on his body and looked back, suddenly stunned: a big hole was blown out of his position just now.
Seven, go out
In ancient times, two brothers each took a suitcase to travel far away. Along the way, the heavy suitcase weighed down the brothers. When their left hand is tired, they have to change their right hand, and when their right hand is tired, they have to change their left hand. Suddenly, Big Brother stopped, bought a pole by the roadside, and hung two suitcases on the pole. He picked up two boxes and set off, but he felt much more relaxed.
It may be far-fetched to link these two stories together, but they do have striking similarities: the little soldier and little brother in the story are lucky, but the captain and little brother in the story are even luckier, because they help themselves while helping others!
Management experience: We will certainly encounter many difficulties in our life. But don't we all know that on the way forward, moving stumbling blocks under others' feet is sometimes just paving the way for ourselves?
Eight, the fish king's son
There was a fisherman who was honored as the' king of fishing' because of his first-class fishing skills. But' Fishing King' is very upset when he is old, because his three sons have average fishing skills.
So a man often tells people his troubles: "I really don't understand, my fishing skills are so good, why is my son so bad?" From the time they were sensible, I taught them fishing skills, starting with the most basic things, telling them how to weave a net to catch fish most easily, how to row a boat without disturbing the fish most, and how to get off the net to invite the fish to the tank most easily. When they grow up, I will teach them how to know the tide and distinguish the fish season. . . I have taught them all the experience I have worked hard for many years, but their fishing skills can't catch up with the sons of fishermen whose skills are worse than mine! "
A passerby heard his story and asked, "Have you been teaching them by hand?"
"Yes, in order to give them first-class fishing skills, I taught them very carefully and patiently."
"Have they been following you?"
"Yes, I always let them follow me in order to make them avoid detours."
Passers-by said, "In this case, your mistake is obvious." You only taught them skills, not lessons. For talents, no lessons can make people great, just like no experience! "
Nine, the apples by the river
An old monk, surrounded by a group of devout disciples. On this day, he told his disciples to go to Nanshan to get a load of firewood. The disciples hurried to the river on the hillside, and everyone was dumbfounded. I saw the flood rushing down from the mountain, and I couldn't cross the river to collect firewood in any case. Without success, the disciples were a little depressed. There is only one young monk and master who are calm and stand opposite each other. When the master asked him why, the young monk took an apple out of his arms and handed it to the master, saying that he could not cross the river to collect firewood. When he saw an apple tree by the river, I picked the only apple on it. Later, the young monk became a descendant of the master.
There are endless roads and rivers in the world. It is also a kind of wisdom to turn around if you can't cross the river. But true wisdom must do one thing by the river: fly the kite of thought and pick an "apple". Throughout ancient and modern times, people who hold such a belief in life have finally achieved a breakthrough and transcendence in life.
Ten, the right hand holds the left hand.
There is a popular jingle on the table: holding your wife's hand is like holding your left hand with your right hand.
Every time someone reads: a table of familiar or unfamiliar people will smile knowingly, and the atmosphere will be relaxed immediately. Of course, this is based on people's consistent understanding of jingles-accurate feeling and appropriate description.
One day at the dinner table, someone read this sentence again, and the men laughed as usual.
Later, I found a woman at the dinner table who didn't laugh. Men are busy talking and joking. Don't take it seriously I didn't expect the woman to say seriously: the best thing is to hold the left hand with the right hand. First, the left hand is most trusted by the right hand; Second, the left hand and the right hand belong to one; Third, how do other hands make you happy and excited? After that, you can chop off your hand, leaving only your left hand. Without it, it's not complete, right? A table full of men admire and praise the profound and unique understanding of women. Women simply say: What is profound and unique? You might as well go back and read it to your wives and see what they say.
Some brave men really went back to test their wives, and sure enough their understanding was the same as that of the ladies at the dinner table.
They are all left-handed, so men should count with their left hands.
They are all right-handed, of course, they think they are right-handed.
Materials with a long history in the motherland:
the Great Wall
The world-famous Great Wall of Wan Li, like a vigorous dragon, twists and turns and crouches on the land of China. The Great Wall of Wan Li, magnificent, is a miracle created by the working people in ancient China, and the most magnificent construction project in the world, which is unique in human history.
The Great Wall of Wan Li starts from Shanhaiguan in Hebei Province in the east and ends at Jiayuguan in Gansu Province in the west. It spans seven provinces, municipalities and autonomous regions, including Hebei, Beijing, Shanxi, Inner Mongolia, Ningxia, Shaanxi and Gansu, with a winding distance of 6,700 kilometers and an area of about10.3 million Li, so it is called the "Great Wall of Wan Li". When people mention the Great Wall, they often associate it with Qin Shihuang. In fact, during the Warring States period before the Qin Dynasty, many vassal states such as Yan, Zhao, Wei, Qin and Han were building the Great Wall to defend each other. Later, after Qin Shihuang unified the "six countries", it took more than ten years to connect the Great Wall built by various vassal countries and expand it on a large scale, making it the majestic Great Wall of Wan Li, which can also be said to be a major military defense measure after Qin Shihuang's reunification. But in many dynasties after the Qin Dynasty, the Great Wall continued to be built until the Ming Dynasty. It can be said that the great project of Wan Li Great Wall was finally completed at the end of Ming Dynasty, forming the scale and appearance of the Great Wall today.
The most prominent feature of the Great Wall is that it passes through mountains, deserts, grasslands and cliffs and is built with the ups and downs of the mountains. Because of the steep terrain, it stands like a flying oriental dragon. Between the Great Wall of Wan Li, countless watchtowers, beacon towers, passes and Fangcheng have been built at regular intervals. There are also many two-story forts built on the city wall. The top of the upper floor is a platform, surrounded by cribs and observation holes, which is convenient for observation and attack. There is a small brick house on the lower floor where soldiers can live and store food and weapons. There are many beacon towers on the commanding heights between the mountains inside and outside the Great Wall. This is used to transmit military information. Whenever the enemy attacks, the beacon tower is lit by smoke during the day and by fire at night, so that the news can spread to the capital quickly even if it is thousands of miles away. Another feature of the Great Wall is to build a Guancheng every 10 km. The size of Guanchengkou depends on the degree of terrain danger and military importance. Among them, the famous Guancheng include Shanhaiguan, Juyongguan, Badaling, Yanmenguan and Jiayuguan. For example, Juyongguan is built 50 kilometers northwest of Beijing. It is built in a deep mountain canyon about 20 kilometers long. The terrain is dangerous, and there is a tendency that "one person guards it and ten thousand people can't". It is the northwest gateway of ancient Beijing, and its geographical position is very important.
In the center of Juyongguan, there is also a white marble platform called Yuntai. Originally, there were three stone pagodas built on Yuntai, which were built in the Yuan Dynasty and have now been destroyed. There is a hexagonal doorway under the platform. On the stone walls on both sides of the gate, there are four heavenly kings and many beautifully shaped Buddha statues carved. The four heavenly kings look bright-eyed and full of strength. There are a large number of stone statues at the door, as well as Buddhist scriptures carved in Chinese, Xixia and Tibetan. These statues and stone carvings were also carved in the Yuan Dynasty, which have high artistic value. Badaling is a part of Juyongguan, with an altitude of 1000 meters and steep terrain. Because the Badaling Great Wall section is particularly steep and majestic, and it is close to Beijing, it was renovated after liberation, and it has been listed as a national key cultural relics protection unit, and now it has become a popular tourist attraction for people at home and abroad.
When you climb the highest beacon tower of Badaling Great Wall, from a distance, the winding Great Wall looks like a dragon, climbing the mountain and swimming to the distant horizon; Look at the fortresses of the Great Wall, one after another, one after another, endless and vast. Seeing such a magnificent scene, a sense of national pride arises spontaneously; The tall and long Great Wall is built on high mountains and cliffs, and the construction difficulty is unimaginable. At this time, you may think: it will be very hard for us to climb the Great Wall empty-handed, so how did we build such a magnificent Great Wall without any construction machinery in ancient times? No wonder people praise the Great Wall as a miracle of human activities, a monument in the history of human civilization and a symbol of the wisdom, strength and indomitable spirit of the Chinese nation. Therefore, the Great Wall is listed as a "World Cultural and Natural Heritage" protection project by the United Nations.
Benefits of scientific and Technological Development
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.
Since the first computer appeared in the United States, people have given computers a glorious mission.
Facts have proved that the appearance of this modern tool not only proves that science and technology have entered a new platform, but also proves that communication between different regions of the world cannot be separated from it. It seems to be the driving force to accelerate social development, weaving a net around the world with invisible chains, trapping development and life.
Science and technology is a weapon for human beings to overcome and transform nature and an important force to promote the development of social productive forces. Every development of science and technology is a leap in the history of human civilization and an epoch-making victory for human beings to conquer nature and self. In the early days of primitive society and slave society, it was precisely because of the casting of bronzes and the use of ironware that social wealth doubled and caused changes in social form. In the industrial revolution in the18th century, it was precisely because of the wide application of steam engine technology that the industrial revolution entered a new stage, thus doubling the wealth of the capitalist world. After the Second World War, it was precisely because of the influence of the third scientific and technological revolution, which mainly focused on electrical appliances, that it greatly promoted the economic recovery of post-war capitalist countries and the substantial economic growth of socialist countries, and promoted the rapid increase of social wealth and the fundamental improvement of people's lives. So the advantages of scientific and technological development are obvious.
Whether people realize it or not, science and technology have deeply influenced our daily life and played an indispensable role in economic and social development. Especially since the 20th century, with the rapid development of science and technology, especially computer network technology and electronic information technology, expensive luxuries such as mobile phones and computers have entered the homes of ordinary people and become necessities of our lives. Imagine how we can keep in touch with our relatives at will without mobile phones. If there is no internet, how can we talk with friends in foreign countries? Without HDTV technology, how can you enjoy gorgeous Hollywood movies? Of course, we must also admit that science and technology have changed our way of life and culture to some extent. Nowadays, more and more young people have accepted fashionable lifestyles such as e-commerce and distance education, and even online dating has become a trend.
It is precisely because of the importance of science and technology that our country has repeatedly proposed to vigorously develop science and technology. Comrade Deng Xiaoping once pointed out that science and technology are the primary productive forces, thus establishing the important position of science and technology, taking the development of science and technology as a basic national policy of our country, increasing the capital investment in scientific and technological development, improving the hard and soft environment for scientific and technological development, and making our country make great progress after the reform and opening up and step into the forest of powerful countries in science and technology. However, we should also be soberly aware that there is still a big gap compared with developed countries such as the United States, Germany and France, and many technologies are restricted by developed countries. Therefore, we must catch up and catch up.
As a member of the current society, we should not only realize the importance of science and technology, but also study science and technology hard, arm our minds with science and technology, have the courage and determination to devote ourselves to science, and use science and technology to develop the broad mind of all mankind. More importantly, we should also educate our future generations to love and respect science.
What exists at present has its rationality.
