Speech on Science and Technology-Dear teachers and students:
When it comes to science and technology, people may first naturally think of artificial earth satellites, manned spacecraft, atomic bombs and other things that seem out of reach. She often gives people a feeling of being above others. In fact, with the rapid development of science and technology, science not only serves the cutting-edge science and technology, but also permeates our daily life more and more. Technology and life have long been inseparable, and technology is everywhere.
During the summer vacation, I participated in the summer camp for young journalists in Beijing. During the days when we were away from our parents, the teacher asked us to inform our parents about our activities every day. When staying in a hotel in Beijing, it is extremely difficult to find a public telephone because people are different and can't walk around casually. IC phone cards prepared before leaving are often lost. At this time, I will especially envy those "group friends" who have mobile phones, and I will deeply feel the convenience that mobile phones bring to people.
In China Science and Technology Museum, we saw the old hand-cranked telephone that can only be seen in TV and old movies, and we also learned how inconvenient it is for people to contact in the primitive way in the era when there is no telephone. Every time I see the footage of party member risking his life to send messages and losing contact signals in the battle, I can't help thinking, if I had a mobile phone, wouldn't I have avoided these unnecessary sacrifices? From time to time, I will be more aware of the power of science. Science has not only changed the whole world, but also changed our lives. Science is all around us.
A few years ago, people called mobile phones "mobile phones" and pagers "BB machines". Making and owning them is something to show off. It seems that this is a symbol of money and status, and it is synonymous with "big money" and "fashion". Today, with the rapid development of science, the telephone has spread to thousands of households. From white-collar workers in companies to ordinary vegetable farmers and even people who collect waste products, their dependence on it is increasing day by day.
It occupies an increasingly important position and becomes an important means of communication in people's life and work. It is obvious to all, from fixed telephone to mobile phone, from single communication tool to color screen and video mobile phone, it makes people's life colorful. Seeing this, you can't help sighing at the rapid development of science and technology.
As a new generation of middle school students, while enjoying our new life, we should set up lofty ideals and aspirations, love science, learn science well and create a new life from childhood. Every student here probably has the same dream. When they grow up, they want to be scientists, produce more scientific research results and contribute to the construction of the motherland and human civilization. This is a lofty goal. In fact, we learn scientific knowledge not only to become scientists, but also to adapt to the ever-changing new life.
Therefore, from now on, we should cultivate a strong interest in learning, study science and technology knowledge hard, learn various cultural classes well, read more popular science books and actively participate in various scientific and technological activities. There is no limit to human wisdom. No matter the Challenger explosion in the United States or the global computer virus upgrade, it will never stop the scientific and technological progress of mankind.
"Knowledge is power", Bacon's famous saying inspired many people who are eager for knowledge. Now, let's use it to motivate ourselves, be a new generation that loves science, and write more brilliant poems for the future of our motherland!
Thank you all.
Speech on Science and Technology II Dear leaders, teachers and dear students:
Hello!
The topic of my speech today is "Science and technology make the flower of human civilization bloom".
As we all know, "technology is the primary productive force." "Innovation is the soul of a nation's progress." Human beings benefit from science and technology, which benefits from innovation, and innovation is the soul of science and technology. From the dream of genetic engineering to the promise of nanotechnology to ensure that you don't have to wash clothes; From the warmth of artificial intelligence "giving you a lovely robot dog" to the spectacle of transgenic technology "making mice grow human ears"
The new technology is changing with each passing day, which makes people ecstatic. Not only that, popular science knowledge has also become the focus of our attention. Einstein, Hawking and Bill Gates are the stars in our minds, and computer science, modern physics and chemical kinetics are influencing us all the time. Science and technology, it represents a spirit, a strength, an innovation and a civilization.
I believe that the place where the spring breeze blows will leave a lot of vitality, because the tenderness of the spring breeze is full of vitality; I believe that the place where science and technology go will sow the seeds of civilization, because there is infinite hope in the fortitude of science and technology. Throughout the history of human civilization, technology is everywhere.
Ancient savage wars began to use fire for cooking, heating and lighting; Cai Lun paper, 1800 years ago, appeared in the streets and courts; Stephenson made the first locomotive; Edison invented the first electric lamp; The submarine dived into the seabed for the first time; The rocket rushed into space for the first time ... every invention and innovation has caused profound changes and great progress in society and deeply shocked the world!
This is the charm of technology! Generally speaking, the high-tech of today's human society-land, sea and air transportation extending in all directions, rapid information and communication technology, laser technology, aerospace technology, microelectronics and computer technology, etc. , are the crystallization of science and technology. From a small point of view, the basic necessities of life are also the benefits brought by science and technology.
Technology has been integrated into life and enriched it. The invention of traffic lights is a traffic civilization, which not only brings convenience to people, but also is a kind of safety, so that people are no longer afraid of busy traffic. Various household appliances have entered thousands of households, and the Internet allows us to be familiar with what is happening in the world without leaving home ... Our life has entered an era of quality and efficiency.
Students, technology is not far away. Do you know that?/You know what? The inventor of Jenny's textile machine is a worker, the inventor of reinforced concrete is a gardener, and the inventor of the lifting basketball stand is a pupil ... ordinary people will have extraordinary creations. Scientific research also shows that a person's success 15% depends on intelligence factors, while 85% depends on non-intelligence factors.
Take action, awaken the sleeping creative masters in our minds, and open the mystery of science and technology with careful patience and perseverance. You will be pleasantly surprised to find that success is not far away, and technology is around you!
The fire is burning for a hundred generations and the lights are shining for a thousand years. Students, let's hold high the flame of civilization and cross the century. Create a beautiful and exquisite life of mankind with the magic and greatness of science and technology. Let China's star of science and technology reflect the splendid culture of 5,000 years, and let the fire of Chinese civilization shine among the nations of the world.
My speech is over, thank you!
Speech on Science and Technology III Dear teachers and students:
Hello, everyone, the topic of my speech today is "scientific and technological innovation helps me realize my dream". Do you know the story of Kuafu every day? That is the exploration of light; Have you ever heard the myth of Jingwei filling the sea? That's the wish of Gaoxia to leave Pinghu. Up and down five thousand years, nine Wan Li. Our ancestors never gave up the pursuit of the unknown and the exploration of science and technology.
We have four great inventions, we have a great mathematician Zu Chongzhi, we have a great scientist Zhang Heng, and we have a great navigator Zheng He. We are proud to have led the world for two thousand years. What is the origin of this? It is their continuous exploration and innovation in science and technology. But we were a century behind the world. Our four great inventions have strengthened the western powers. They used our own inventions to break through the dilapidated doors of China. History has proved time and time again that backwardness will lead to beatings.
So we bow our heads proudly and we work hard. We have made atomic bombs and hydrogen bombs with our local workshops, and China's "Oriental Red" can be heard in distant space. Chang 'e I flew to the moon, Shenzhou VI, Shenzhou VII and Shenzhou VIII were successfully launched, and our high-tech Olympics were realized. We in China have made progress, developed and become rich, and our Chinese nation has become stronger.
Now we have an indispensable personal item in our life-mobile phone. Adults have used advanced mobile phones with functions such as music, Bluetooth and taking photos, and even children have used low-radiation and practical "special machines for students". Once, I left my book at home, and it was too late to get it home. At this juncture, I remembered my savior-mobile phone! I used it to contact my family and solve this urgent need.
I am very happy to live in this high-tech era. According to the elders, they contacted each other by email at that time, and it took at least ten or eight days to reach each other's hands, and the "urgent" things became "no hurry". In those days, the fastest thing was to send a telegram. Later, in the "telephone" era, communication was much more convenient. Now in the internet age, news spreads faster, and people can make things clear as soon as they get online, no matter big or small. Isn't this the most favorable embodiment of scientific and technological innovation in life? There is no development without scientific and technological innovation.
Students, the times tell us that the motherland needs successors with knowledge and culture. We should work hard, study hard, be useful talents to our country in the future, and make our motherland more prosperous and strong.
Thank you, my speech is over.
