What changes has the development of science and technology brought to human life? Please help me wri

As soon as I entered the house and put down my school bag, I couldn't wait to shout loudly, "Mom, Mom, come here, please tell me, what changes technology has brought to us?" Mom said

Look at you, like a fire burning your eyebrows, let me tell you slowly. Technology has brought so many changes to people. For example, the invention of the earliest gunpowder enabled human beings to split mountains and open roads, build bridges, and build, which led to the development of various undertakings, and the military industry also developed rapidly; With the advent of papermaking and printing technology, human beings have the conditions for writing, and have promoted extensive exchanges in culture, art, language, science and technology, economy, etc.; The invention of the compass promoted the development of navigation and the world, completed the great geographical discoveries, and enabled mankind to understand the earth; The current scientific and technological achievements of hybrid rice and super rice have increased grain production and solved the problem of feeding the world's population; Like a god.

Five, God six....These shuttles helped astronauts get to the moon, explore Mars, and roam space; Sputnik provides us with satellite images and weather forecasts, as well as television signals. Robots can do many things that humans can't, such as diving into the deep sea to investigate, breaking into fires to save people; The maglev train is particularly fast, saving people time when traveling; People use atomic energy to generate many, many more electricity...

Two people are separated by thousands of mountains and rivers, but as long as they pick up the earpiece and dial a few numbers, it doesn't take a few minutes to hear each other's voices and communicate in language, which is the miracle that ** brings to human beings. It's not enough to have **, human beings have invented computers, computers are better than **, **can only hear each other's voices, and computers can communicate in text, and can also **talk, and can see each other. If there is a holiday, send an e-mail, and the other party can receive it in a few seconds, which can not only save paper, but also quickly let others receive ......The development of science and technology has improved our living standards and improved the quality of life!

In the 20th century, human beings invented many useful items for us, such as: computers, televisions, ......These items make it very convenient for modern humans to do something.

Brat. The exam won't be written here to ask for answers.

With the development of global science and technology, our lives are becoming richer and richer. Subway, high-speed rail, airplane, **, mobile phone, automatic elevator, etc. These technological developments have changed our lives.

The maglev train does not run close to the rails, but in the form of levitation, on the track surface. Originally, it used the principle of attraction and repulsion of electromagnetic induction to make the body of the train float, and then the electricity generated by solar, wind or water power propelled the train forward. This kind of train will not be noisy, safe and stable, and will not pollute the ecological environment.

Japan's maglev train uses the force of the magnetic field induced by electromagnets and coils to levitate the body. The maglev train in Birmingham, England, uses the force of the magnetic field between the electromagnetic and the track to levitate the train.

The cement mixer truck is here to transport the mud, and the construction site uses scattered mud blocks. In order not to make the muddy water form a hard lump, he rolled as he walked. There is a large sports carriage that is also a round car, which is used to transport liquids.

There is a certain reason for the circular design of the tanker, first of all, the volume of the same surface material is enclosed by a circle; Then it is round and has no corners and is not easy to break. The round tank is also under relatively uniform pressure.

Sputnik is a high-tech communication building, and every few years the world must launch an artificial satellite. The satellite is composed of a star, a state-of-the-art device, a receiving and transmitting antenna, a solar power system, an attitude control system and an orbit control system. We have seen that thousands of miles away TV programs are received by satellite transmitting antennas to various regions, and some auxiliary devices are also provided.

This way, we can see TV shows thousands of miles away.

High-rise buildings are common in cities, because the land price is expensive, so they have to use high-rise buildings. The formation of high-rise buildings is varied, with square columns, circles, prismatic shapes, etc. The common slotted building, like a rectangular building block, is less resistant to wind.

The cylindrical building has good wind resistance, and the famous buildings with cylindrical shape include the Peachtree Center Plaza Hotel in Atlanta, USA, which is the tallest conical hotel in the world. The cone-shaped building has the best wind resistance and is relatively strong in earthquake resistance.

Technology is changing our lives, and technology is leading us into a new society. As long as we love science, study science, and observe science, we can create a perfect realm!

The development of science and technology has promoted the progress of society and human progress, such as the invention and improvement of the steam engine in the first industrial revolution, which pushed mankind into the steam age, and the social productive forces have developed greatly; The application of electricity in the second industrial revolution ushered mankind into the electric age.

Promote people's way of producing, living and thinking. It has promoted the development of productive forces, improved people's material and spiritual living conditions, and improved people's quality of life. Speed up the pace of social life, and change people's way of work and rest, the way of communication, the way of learning, the way of consumption, and the way of entertainment.

Bring us into the information age. It provides us with the means to process, store and transmit information, and brings convenience to study and work. Modern means of transportation and communication have made the earth smaller and people can communicate easily and quickly.

Computers are also frequently used by us in daily life, we can look up information on the Internet, learn nursery rhymes, listen to English, learn mathematics, and do Chinese. Looking at various review materials, gradually, computers have become an indispensable daily necessities in our lives.

The most important thing about technology is the daily use: during the Chinese New Year, those migrant workers who work outside have to go home, the bus is too crowded, the train is too slow, no, the plane and maglev train are useful, and the migrant workers can get home quickly; In the summer, mosquitoes, flies and other pests fly everywhere, only relying on mosquito coils can no longer deal with those arrogant mosquitoes, electric mosquito coils, electric mosquito swatters and other new technology products have been listed, they are deeply loved by people.

The role of technology is very wide-ranging, it can help humans improve their lives, increase work efficiency, solve problems, etc. Here are some of the key roles of technology:

Improve production efficiency: Modern technology can help enterprises and organizations improve production efficiency and quality, reduce cost and time, and thus improve economic efficiency.

Improving quality of life: Technology can improve people's quality of life, for example through medical technology, transportation, smart homes, etc., to improve people's health, safety and comfort.

Problem solving: Technology can help human beings solve various problems, such as environmental protection technology, energy technology, etc., to solve environmental and energy problems; Solve business and social problems through information technology, data analysis, etc.

Promote cultural exchange: Technology can facilitate communication and communication between different cultures, such as through the Internet, social networking, etc., making it easier for people to communicate and share information, thereby increasing mutual understanding and respect.

Promote scientific progress: Science and technology are the products of science, which can promote scientific progress and innovation, develop new products and technologies, and create new business opportunities and employment opportunities.

In short, science and technology play an irreplaceable role in the development and progress of human society, and its application scope and influence are becoming more and more extensive.
