Rejuvenate the country with science and technology and dream of the future.
As we all know, science and technology rejuvenate the country and create the future. Our food, clothing, housing and transportation are inseparable from the contribution of science and technology. In this special winter vacation, I watched a program called "Smart China", which was deeply attracted by the super tram and I sincerely lamented the incredible and rapid development of science and technology.
At present, the traffic problem is one of the biggest problems facing all countries in the world. Road congestion causes road congestion, and many times, we are helpless. And modern high-tech technology makes us see hope and future.
China invented a green and environmentally-friendly super-tramcar without cable, which can charge 10 second without cable and travel 10 km. The back of the tram is equipped with a super charging capacitor, which can store a lot of electric energy at high speed, release electric energy and recharge it. When the car arrives at the station, the receiver rises at the top, connects to the power supply and automatically charges. It can be fully charged within 30 seconds to generate 1800 A current. A super capacitor has 600 small capacitors and * * * has 43 modules. The two are connected in series, and can be replaced as needed, which is convenient, quick and long in service life.
Environmental protection, energy saving and novel appearance are also its main design features. It uses the motor to convert kinetic energy into electric energy, which is stored in the capacitor for reuse, saving 30% energy consumption compared with traditional trams. More innovative in appearance, bid farewell to the ugly antenna, only need to lay the track, perfectly avoid the problem of wire leakage and avoid secondary economic losses. The whole vehicle-mounted system is very advanced, and it can also prevent fire, pressure and shock! This was created by a great craftsman, China! This is a unique innovative technology invented and created for the first time!
The development of science and technology has brought us a happy and beautiful life, and China is heading for the peak of science and technology. Successfully entered the scheduled orbit from the first artificial earth satellite "Dongfanghong-1"; From the successful launch of the first recoverable remote sensing artificial earth satellite ... to the completion and commissioning of the world's largest single-aperture radio telescope "Shenwei Light of Taihu Lake" and the successful launch of Mozi ... the horn of a powerful country in science and technology has taken root in China!
"Science and technology are the primary productive forces, and innovation is the first driving force to lead development." Technology will lead us into a better new era. As a new generation of teenagers, we should study hard and make contributions to our motherland!
Rejuvenate the country with science and technology and dream of the future.
With the rapid development of science and technology in China, stories such as "the Goddess Chang'e flying to the moon" that the ancients thought have now become a reality.
From "silver" to "copper coin", from "silver ingot" to "RMB", and now to "Alipay", human beings have various payment methods, which also make people's lives more convenient and beautiful.
That time, I went to the interest class alone, and my father asked me to bring six yuan. I said, "Oh." But I didn't mean to. I packed my schoolbag for a while and forgot about it. I set off with a useless schoolbag on my back.
When I arrived at the bus stop, I suddenly remembered that there seemed to be no change. I hurriedly opened my schoolbag and rummaged around for a while, but I didn't see any traces of coins. I looked up, first with a blank face, at a loss. Then "anxiety", "anxiety" and "helplessness" welled up from my heart. I looked at my watch. It was not far from class time. And the bus is already at the intersection, as if provoking me and saying, "Come here."
At this imminent moment, I have to choose to ask my father at home for help: "Hey, Dad, I forgot my change and can't take the bus." "You can't be so so-so, so I'll transfer six dollars to your mobile phone. You pay by mobile phone. " I'm relieved to hear that. Get in the car and wait until everyone else has paid. I took my mobile phone and asked an uncle next to me, "Uncle, will you help me pay with my mobile phone?" "Of course." My uncle happily took my mobile phone and helped me pay for the cash register. Then a big stone fell to the ground.
After sitting down, I couldn't help feeling that I was almost late, saying that this mobile payment is really convenient and fast. I paid the money with a click.
Because of the development of science and technology, our payment is faster; Because of the development of science and technology, our travel is more convenient; Because of the development of science and technology, our life is more interesting ... technology has changed our life and made it better.
Rejuvenate the country with science and technology and dream of the future.
When I think of the word motherland, I feel extremely excited. Magnificent mountains and rivers, long history and splendid culture are the pride of China people. Recall that when we were bullied by foreigners, you came out of dangerous difficulties again and again. Today, we listen to March of the Volunteers and look back on the past, which encourages us to forge ahead. "Get up, people who don't want to be slaves, ..."
According to my grandparents, before the founding of New China, China was poor and backward. The people of China have been invaded by foreign powers, and the people are living in dire straits. The country's economy is poor and backward, and its military strength is weaker. There are no advanced military weapons, but millet and rifles. Now our aircraft carrier, Dongfeng series, our fighters, bombers and other most advanced weapons and equipment have mushroomed. Witnessed the struggle of our country from standing up to becoming rich and then becoming strong. Now our country has a certain position on the world stage, and our diplomacy has a certain right to speak. I saw from CCTV news that Italy joined the Belt and Road Initiative and returned 796 sets of cultural relics from China.
I can't help but think of the text "Burning Yuanmingyuan" in the fifth grade textbook. China's cultural relics are not just Italian. At that time, Eight-Nation Alliance broke into Yuanmingyuan and robbed rare treasures. I don't know how many cultural relics China took and set fire to Yuanmingyuan. Learning this text will arouse our hatred for the barbaric acts of the invaders, remind us not to forget the national humiliation and increase our sense of responsibility and mission to revitalize China. Now Italy has returned 796 sets of cultural relics to China, which is the return of cultural relics! This fully expresses that all self-esteem and discourse power are based on the strength of the country! I am proud and proud of the strength of my motherland!
As teenagers in the new era, we have the obligation and responsibility to make our own contribution to the prosperity and development of the motherland. Rejuvenating the country through science and technology is not an empty talk. I know very well that serving the motherland requires a strong body, rich knowledge and superb skills. So I want to cherish time, exercise, study hard and enhance my sense of innovation. Only when you grow up can you serve the motherland. A thousand words can be summed up in one sentence "awesome, my motherland, I love you forever"!
Rejuvenate the country with science and technology and dream of the future.
Forty years of hard work, seventy years of songs have never ended, and the spirit of a hundred years will last forever. Today, under the guidance of the May 4th patriotic banner, the people of China are making progress and saving the country scientifically. With a glimmer of light, the Chinese dream is infinitely bright today, and it can't be separated from generation to generation. As contemporary youth, we shoulder the heavy responsibility of rejuvenating China and rejuvenating the country scientifically.
Rejuvenating the country through science and education is a historical revelation. At that time, we were immersed in the dream of "going to China" and didn't know it. Little did I know that after the industrial revolution, science and technology developed rapidly, and western civilization gradually left us behind. When the western powers bombarded China's long-locked gate with their strong ships, this prosperous Millennium land left endless scars of blood and tears. A century of humiliating history has concentrated the inability of the Chinese nation to fight and will eventually awaken the sleeping nation. Lu Xun said: "We make gunpowder into fireworks, but the west makes cannons." The stagnation and backwardness of science is the fundamental reason why China's national strength lags behind that of the West. The May 4th Movement held high the banner of saving the country through science and awakened China.
Rejuvenating the country through science and education is the inspiration of the times. What we are concerned about is today's China, where the economy has developed rapidly and has leapt to the forefront of the world. Linda once said, "piercing the sharp ice on the water surface may only expose a corner." We should not only see the high speed of economic growth, but also see that under the speed, energy-driven industries are facing resource depletion and environmental pollution; Labor-intensive industries are facing a decline in demographic dividend and weak growth; The core technology of high-tech industry is restricted by the predicament of developed countries. No matter how prosperous and beautiful the economic flower is, without the support of science and technology, China's economy will continue to develop. How can the Chinese dream be realized? We must re-examine this era, which is an era of rapid development of technology. As the primary productive force, science and technology have been proved in countless practices. In the era of knowledge economy, the prosperity of a country should be based on science and innovation.
It is our responsibility to rejuvenate the country through science and technology. Ibsen, a Norwegian playwright, said: "Society is like a ship, and everyone should be ready to steer at any time." What we have to do is to relay China's mission of rejuvenating the country through science. We can see that our ancestors have taken a solid step for us, from the May 4th banner of rejuvenating the country through science and education to the "863" plan and the strategy of rejuvenating the country through science and education, and then to the launch of the Shenzhou series spacecraft, the yield per mu of hybrid rice has once again broken through. I see that from Deng Jiaxian's obscurity to Tu Youyou's persistence, and then to South's lifelong persistence, countless predecessors' efforts have created today's booming China. And our generation should be more ambitious and continue to promote the Chinese dream at the speed of high-speed rail.
This is a country full of hope, and this is an era full of vitality. "We are all trying to run, and we are all dream catchers." May contemporary young compatriots arm themselves with scientific power and relay the dream of Chinese rejuvenation!
Rejuvenate the country with science and technology and dream of the future.
The voice of "learning for the rise of China" has awakened thousands of China people in Qian Qian. Since then, China has hope and China has a future.
Reading has opened up the world and a brand-new time and space for us. From the book, we can appreciate the magic and beauty of science, touch the slightest change of science, interpret the variety of science, and let us see different experiences. While reading, we feel the freedom of science to change our lives, at the same time, it also purifies our souls, improves our literacy and enriches our knowledge, which can be described as various. Therefore, in order to improve our self-cultivation and enrich our knowledge, we should study. Science and technology are the primary productive forces and play an important role in the development of human history.
I have a dream, a great dream of science and technology, a dream of strengthening the country through science and technology. I want to set up a chip company independently developed by China in China, and build a scientific and technological world belonging to China. As early as 2500 years ago during the Warring States Period, China had mastered six alloy technologies and their uses. As early as the Western Han Dynasty, China people invented papermaking; Around the 3rd century AD, China people had invented ceramics. In the Tang Dynasty, China people invented gunpowder; In the Song Dynasty, China people invented the compass and movable type printing ... However, all this has become a thing of the past. Since the 1960s, China's long-term "closed door" policy has seriously affected the spread and development of modern science and technology in China, leaving it in a relatively stagnant state. But in the following centuries, the United States, Britain and Japan became developed countries with strong national strength by developing science and technology. Among them, the United States has several world-class companies such as Apple, Microsoft and IBM, ranking first in the world, followed by Britain, Japan, Germany and Finland, and Greater China is far behind.
I like science, and I want to bring prosperity to our motherland. I am eager to be China's Steve Jobs, which is my thirst for knowledge, my hope for innovation and my pursuit of perfection. I want to change myself, China and people's lives with knowledge.
