How else will scientists change our lives in the new century?

When we sit in front of the couch and watch the TV with relish; When surfing the Internet on a computer; When writing homework under a desk lamp; By car, by high-speed rail, by plane when traveling ......Ever wondered how all this came about? Yes, it was created by industrious and intelligent human beings.

Hundreds of years ago, when people wanted to greet their relatives in distant places or report safety, they needed to send someone to bring letters or words to their relatives' homes, and sometimes they used flying pigeons to pass on books, which was laborious and time-consuming, and could take more than a month to ......in order to reach the hands of relatives. It has become very difficult for people to communicate. But today, people don't use these traditional methods anymore, why is that?

It turned out that in 1945, two professors at the University of Pennsylvania in the United States, Mochley and Eckert, designed and developed the computer. With the advent of computers, now look at what people are doing. People who love to learn, they continue to absorb knowledge from the computer, and get the knowledge they want very quickly and accurately; There are also people who play games after being busy to relax their stressful lives; Others are chatting with distant relatives and friends, shopping online ......Computers make people's lives full of life and fun.

In the past, people had nothing to do at night after a busy day, and people's lives became empty, monotonous, and boring. But the intelligent human beings invented television, this invention not only changed people's monotonous life, but also allowed people to understand the world through television, see the scenery and things that they had never seen before, opened people's eyes, and people's lives changed and became colorful.

In ancient times, people wanted to go far away, and it was quite difficult. At that time, many people rushed to take the exam, and due to the lack of transportation, they had to ...... a month in advanceIn order to catch up with the time, the candidates are very tired, and there are even people who regret not catching up for life. In the past, when people saw the moon, they were always reverie about the beauty of the moon, and there were many beautiful legends, and it was just a dream to go to the moon.

But today, scientists have solved many difficult problems with their brilliant minds, and achieved people's unattainable dreams, they have invented cars, trains, airplanes, rockets, ......Now, when people go far away, they don't have to go out half a year in advance; If you want to go abroad, that is, you can arrive in about 1 day, and if you want to get on the moon, then you can directly get on a rocket to see the true face of the moon and explore the mysteries of the moon. That's when people realized that we were actually very close.

As human beings become smarter and more advanced, science and technology are becoming more and more advanced, but we ignore many things, look at our surroundings, the modern ** invented by human beings is making people in war suffer disasters and life becomes fearful; Factories are producing on a large scale, the environment is getting worse and worse, and the earth is becoming miserable .......

So, in the 21st century, the development of technology has met the needs of many people and changed people's lives at the same time, but I hope that these changes will be positive and bring people benefit and happiness, rather than disaster and pain.

Whatever you think of and what can be theoretically established, you will be able to achieve it.

Outer space colonization, artificial creatures, robot worlds, quantified emotions, cyber domination,

Never rely on the immortal emperor, rely on yourself to improve your life.

Clothing: nanomaterials, elastic fibers are added to clothing. Increase and enhance the functional characteristics of the fabric in terms of waterproof, oil-proof, anti-fouling, breathable, antibacterial, environmental protection, not easy to change color, comfortable feel, etc., improve and enhance the wearing performance of the textile wearing fabric, and endow the fabric with antibacterial health care and ultraviolet shielding.

New features such as oil repellency and easy care.

Food: The advent of convenience food has made people's lives easier. The emergence of green food has improved the quality of people's food, and people have no season for eating fruits and vegetables, such as watermelon in winter and sweet potatoes in summer.

The emergence of water purification technology has solved the problem of urban drinking water quality.

Housing: The use of solar energy has brought many benefits to human beings: 1. The reserves are not exhausted (about 5 billion years). 2. It will not produce exhaust gas to pollute the environment, so it is more and more valued.

Intelligent community and home intelligence: realize anti-theft alarm, help alarm, gas leakage alarm, fire alarm, automatic collection of water, electricity and gas and other meters, remote home appliance control, and personal information services. Even thousands of miles away.

Remote control of the air conditioning equipment in the home for temperature regulation, home appliance control, lighting adjustment, when the family security alarm (including: theft alarm, fire alarm, gas leakage and disease emergency call, etc.).

Line: Bridges and tunnels, Shanghai's existing Xupu Bridge and Lupu Bridge.

Nanpu Bridge, Yangpu Bridge.

Dapuqiao Tunnel, Fuxing East Road Tunnel, Yan'an Road Tunnel, Dalian Road Tunnel.

Tunnels and bridges greatly connect the Huangpu River.

The two sides of the strait have brought us convenience.

Electric lights, mobile phones, the Internet, drug development, sewage treatment technology, these are all common. Other large-scale large-scale production has a big impact.

Science and technology that have a greater impact on our lives are: the invention of electric power technology, which makes the gap between our day and night life smaller and smaller; The invention of Internet technology has shortened the distance of space all of a sudden.

Our life is inseparable from scientific and technological inventions and creations, such as the development of network technology, which makes us use smart phones, smart payment is very convenient, and machinery manufacturing makes us drive cars, take high-speed rail, and travel conveniently.

Writing ideas: Simplify the task language directly. In the narrative, we need to turn the direct narrative into an indirect narrative, simplifying the language of the characters as much as possible. In this way, even if the plot is coherent, the sentence is "concise".

Today, the teacher assigned an essay. The requirement is to read the text taught today to your father or mother, ask them to talk about the changes brought about by the development of technology, and then write down their words.

In the evening, when my dad came back, I couldn't wait to ask, "Dad, could you please tell me what changes technology has brought us?" ”

Dad said: "Modern science and technology have developed, and the invention of water heaters, electric lights, etc., has added convenience to our lives. I asked, confused

Dad, how did you live back then? Dad said, "At that time we could only boil water with coals, light lamps with matches, not as comfortable as now, water heaters, electric lights.

I broke the casserole and asked, "Dad, how did you harvest and eat at that time?" "Dad said

In the past, the harvesting tool was a sickle, but now with the harvester open, the farmer sits on the harvester, smiling like a blooming flower. These high-tech technologies have brought farmers the joy of a bumper harvest and infinite hope, and the development of these technologies has brought one surprise after another to our lives. ”

Yes! Today, with the development of science and technology, our life is getting better and better, and I believe that through our continuous efforts, our life will be the icing on the cake!
