Major scientific and technological achievements such as "two bombs and one satellite", hybrid rice, manned space flight, deep-sea exploration, c9 19 aircraft, and eye telescope are inspiring. National projects such as Qinghai-Tibet Railway, Three Gorges Project, South-to-North Water Diversion Project, West-to-East Gas Transmission Project and Hong Kong-Zhuhai-Macao Bridge have been reported frequently, and high-speed rail, mobile payment, economic enjoyment and online shopping have led the trend. But, you know what? These great achievements are inseparable from the help of science and technology.
-said: "Now we are closer to achieving the goal of the great rejuvenation of the Chinese nation than at any time in history, and we are more confident and capable of achieving this goal than at any time in history." This is all because of the rapid development of science and technology. A grand military parade was held in Tiananmen Square. In the whole parade, * * * has 47 ground teams, 12 air echelons and 32 equipment teams. 40% of the weapons displayed by the equipment team are made in China for the first time. It can be seen that science and technology in China are developing rapidly.
With the development of science and technology, China's "millet plus rifle" in the Korean War has become the present "rocket plus missile", making China no longer invaded by other countries. After years of ups and downs, the people of China can finally live in peace! It can be seen that technology and human beings complement each other. Without science and technology, the quality of human life will be poor and unsafe. However, without human beings, science and technology could not appear on the earth. Therefore, while enjoying the convenience brought by science and technology, we should also shoulder the responsibility of developing new technologies.
In the past 7 1 year, the science and technology in China has been greatly improved. But those scientists are still not satisfied. They still soak in the laboratory every day to study the technical problems that may be broken, and devote their lives to China. We should also have this spirit and be willing to dedicate ourselves to China.
The development of science and technology can not be separated from the promotion of people. Throughout the ages, how many scientists have devoted themselves to solving difficult problems. They have been working for more than ten years, even decades. Only in this way can China be strong and free from bullying. Their persistence paid off: as the problems were overcome, the new China became stronger and stronger. Now, China has changed from passive defense to active attack. Great achievements have also been made in science and technology.
The phrase "science and technology make the nation prosperous, and science and technology make the nation strong" has also become the "mantra" of everyone in New China.

Last summer, I visited Xi 'an-9 Space City.
As soon as you enter the door, there are so many models of planets, rockets and satellites that people are dazzled. Suddenly, I have infinite curiosity and fantasy about the universe. Walking inside, the lights gradually dimmed, and there were many bright stars in the sky, which made me feel that I was really walking in space. Then, when I entered a room, a huge satellite probe model came into view, which included the earliest manned rocket ship Shenzhou-1 and the most advanced rocket ship Shenzhou-13 in China, both of which surrounded this big satellite. Facts have proved that our country has made so many achievements in space in the past 50 years. These achievements were bought by space heroes with their youth and precious lives, and I can't help but feel awe for them. A strong teenager makes a strong country. When I was a teenager, my space dream came to me.
In order to light up my space dream, I immediately experienced the space simulation project.
Walking on the moon. This project is to simulate astronauts walking on the surface of the moon and tying ropes on a higher platform. The rope is very elastic and can simulate weightlessness and walk on a sponge. Because the sponge layer is low and the rope is elastic, it is difficult to walk without falling off. We are already struggling in our own clothes. Imagine how difficult it is for astronauts to walk in spacesuits that are many times heavier than our clothes and complete their tasks. Being an astronaut is not an easy task. You must have the spirit of hard work.
Then, I went to experience the project of returning to earth. This project is to experience the process of astronauts returning to earth in a return capsule. I walked into the VR room, put on VR glasses, and the chair kept spinning and shaking. Directly below is the earth. As we get closer and closer to the earth, the bottom of the return capsule is rubbed by the impact of the atmosphere, as if it were on fire. In the end, my legs were weak and my head was dizzy. Astronauts really have to fall from 10 thousand meters high and suffer indescribable discomfort. To be an astronaut, you must also have the spirit of dedication and sacrifice.
After the experience is over, I can't be calm for a long time, and I have a clearer direction for my space dream. We should strengthen physical exercise and have a strong body; Secondly, we should study the knowledge of culture class harder. Only through my own efforts can I approach my space dream step by step and make contributions to the space cause of the motherland. Come on!

"Without the Party, there would be no new China" is the first red song I heard. This song was written by Cao zai 1943, which aroused my interest in knowing the party and understanding it.
192 1 On July 23rd, China * * * Party was formally established. At that time, the environment at home and abroad was very severe and stormy. Our party led the people through many difficulties, and finally established People's Republic of China (PRC) in June 1949+ 10/.
After the founding of People's Republic of China (PRC), China, the sleeping oriental lion, began to wake up slowly. Industry, agriculture and other fields have developed rapidly, among which the development of science and technology is particularly noticeable.
From 65438 to 0964, China's first atomic bomb exploded successfully in Lop Nur, Xinjiang, indicating that China has reached a fairly high level in atomic bomb theory, structural design, design and manufacture of initiation control system, etc.
1965, a team of Chinese scientists synthesized the bioactive protein-bovine insulin for the first time. The success of this experiment not only caused a sensation in China, but also changed the international attitude towards China. Because this is a major breakthrough in human biological science and a big step for human beings to understand life and uncover the mystery of life.
1966, Chen Jingrun, a young mathematician in China, worked it out by hand with a lot of manuscript paper in a hard research environment, and successfully proved Goldbach's conjecture, one of the three major mathematical problems in modern times.
1970, China launched the first artificial satellite "Dongfanghong-1", making China the fifth country in the world to independently develop and launch artificial earth satellites.
From 65438 to 0973, Yuan Longping cultivated hybrid rice "Nanyou No.2" by using genetic diversity, and developed a set of seed production techniques. After the large-scale promotion of "Nanyou No.2", the total grain output in China has been greatly improved, which makes China solve the grain problem of 22% of the world population with less than 10% of the world's arable land.
……
These are the results of the unremitting efforts of the people of China under the leadership of China's * * * Production Party.
-once said: "If China wants to be strong and revitalize, it must vigorously develop science and technology and strive to become a major scientific center and an innovative highland in the world. We are closer to the goal of the great rejuvenation of the Chinese nation than at any time in history. We need to build a world science and technology power more than at any time in history! " As a Communist Youth League member, I want to learn scientific and cultural knowledge, integrate innovative ideas into my study life, and sing the main theme of the new era and new journey of the Chinese nation.

The ancients once said: Young people are wise, rich and strong. Since the founding of New China more than 70 years ago, generations of China scientists and engineers have made pioneering efforts to catch up with the world's scientific and technological powers step by step and made amazing scientific and technological achievements. History has proved that our young people in China are wise and strong. The waves behind the Yangtze River push the waves before, making our motherland stand tall in the east of the world.
In 2020, this extraordinary spring, there will be no firecrackers and no lively visits. Novel coronavirus challenged our life, and brave angels in white accepted the challenge without hesitation. Facing the menacing novel coronavirus, angels in white sacrificed his holiday and went to the battlefield, guarding our safety with his life. In order to win this war without smoke, many scientific research teams are also eager to try, and have developed high-tech products about medical care. With the remote monitoring system, the patient's condition can be known at any time, which not only reduces the contact between medical staff and patients, but also improves the efficiency of patient condition detection. There is also a shelter processor for treating medical waste, which can not only treat medical waste in time, but also make medical waste not damage the environment. It's killing two birds with one stone! China and Qixin joined forces to defeat the virus in the fastest time and saved lives.
As a primary school student, I want to study hard, become an excellent artificial intelligence developer, develop more advanced artificial intelligence products, defend the country and people, and contribute my youth and strength to the development of the motherland.

Our motherland is a country with a long history and culture of 5,000 years, leaving many treasures that we are proud of. With the development of science and technology, we can understand them more and more deeply. In "National Treasure", the cultural relics themselves or the creative process are displayed in a three-dimensional way by means of science and technology, and the rare products are displayed in front of us, leading us into a mysterious exploration space. What impressed me the most was that in the explanation of the coloring process of "A Thousand Miles of Rivers and Mountains", I relied on the big screen to restore and show it layer by layer, which gave me some intuitive understanding of the painting technology at that time and was even more amazed at the author's wisdom.
In the restoration of national treasures, it is inseparable from the help of modern high technology. Due to the long time and environmental impact, cultural relics have been damaged by physical and chemical reactions to varying degrees. Masters of cultural relics restoration will use high-powered optical magnifiers, ultrasonic cleaners and other high-tech instruments to make cultural relics restoration more convenient, and then bring the treasure back to life through their hands.
I like these national treasures very much and I like the stories behind them. Every time I look at them, I am full of pride. With the further development of science and technology, I believe more treasures will be discovered, and more history and culture will be explored.
I hope that when I grow up, I can be one of them, bring home our treasures from ancient times to the present, let their lives glow again, let the world know China again and see China!
I am deeply proud that our motherland is so powerful.

Recently, a piece of news exploded on major social networks and became a hot topic of discussion, that is, "Tian Wen No.1" frequently boarded hot searches.
Tian Wen-1 is the probe of China's first Mars exploration mission. Its name comes from Qu Yuan's long poem Tian Wen, which expresses the Chinese nation's pursuit and persistence of truth, embodies the cultural inheritance of nature and space exploration, and implies that the journey of exploring scientific truth is long and the pursuit of scientific and technological innovation is endless.
On July 23, at 12, the Long March 5 remote 4 and Tianwen 1 probes were launched at Wenchang space launch site. There was cheers at the launch site, and many people cried for it. Looking at the motherland with such advanced technology, who can not be moved and proud of it?
On July 27th, various scientific research teams actively cooperated to let "Tianwen No.1" look back at the Earth and successfully obtained a photo of the Earth and the Moon. In this picture, the earth and the moon are opposite from a distance. Although it is only a small spot on the earth, it represents another great achievement of China.
China will never give up exploring. I believe we will succeed!

Dear teachers and students:
Hello everyone! I come from the sixth (second) squadron. The topic of my speech today is "science and technology hold up the dream of a strong country"
History is like a few stars in the vast starry sky. I brush past quietly, looking forward to gorgeous and precious wealth, and sometimes looking up at the brightest stars, silently wishing and flying quietly. The Chinese dream lingers in my heart.
The bright Milky Way flows through the five years of drought in China. From the creation of Pangu to today's advanced technology, I have seen a lot, listened to a lot and watched a lot. Everyone in China has the same Chinese dream. The Chinese dream flows in every day and night, in the heart of every China person. The Chinese dream, the dream of strengthening the country, has been haunting me.
Technology makes dreams come true. After several generations of scientists' unremitting efforts, Shenzhou 10 was launched to greet the Heavenly Palace, the Goddess Chang'e flying to the moon explored the moon, and the dragon was searched for the Dragon Palace in the deep sea. The service of the aircraft carrier showed its national prestige. When the applause thundered and the whole world focused on China, I knew that the light of China had spread to every corner of the earth. The Chinese dream is still going on, and our motherland will once again bear fruitful results.
The sun is shining, I am standing under the blue sky and white clouds, looking at the motherland that is gradually becoming rich and strong. With a strong heart, a glory, and a memory, hold out your chest and encourage yourself: remember the Chinese dream, study hard, silently contribute your meager strength, and create a better future for China.
My speech is over, thank you for listening!
