I heard the teacher say the word "science" when I was a child. I didn't understand its meaning at that time. All I know is that I can't suck my fingers because I have bugs in my hands. You have to take an injection and take medicine when you eat. When I entered primary school, I met some great scientists, such as Galileo, Einstein and Qian Xuesen ... At that time, I had a reverence for scientists and a desire to study science. Now, I am a seventh-grade student. I am on the great ship Discovery, sailing in the ocean of scientific knowledge: from creatures, animals to plants, from the solar system, the Milky Way to the boundless universe, we find the truth through study, experiment and observation.
Opening the thick history and seeing a series of horrible historical fragments, my thoughts were taken to the dark old China-100 years ago, foreign powers made guns with gunpowder invented by our ancestors and slaughtered countless Chinese sons and daughters; More than 70 years ago, Japanese imperialism ravaged the land of Jiuzhou and wantonly pursued the "Three Lights" policy, killing many people in China. ...
Looking back on the history of blood and tears, let us always remember that the country should be strong, science and technology should develop, and backwardness should be beaten.
Look! After the founding of New China, the country became increasingly prosperous, science and technology developed gradually, and China was taking off. From China's restoration of the legal status of the United Nations to China's accession to the World Trade Organization, from China's successful development of "two bombs and one satellite" to the successful realization of manned space flight, these marks China's great achievements in politics, economy and military affairs, and are brilliant achievements of China people's unremitting self-improvement and scientific and technological development. China has really risen! Chinese people are proud of this.
Science benefits mankind and science benefits the future. As the successors of the motherland's construction, the future of science lies with us, and we have a long way to go. We suck the South Lake water, remember the teacher's inculcation, explore knowledge under the cold window and study hard. "Let's stand on the shoulders of scientific giants, uncover more scientific mysteries and create more brilliant scientific and technological civilization!"
Everyone is familiar with the word technology. Computers and televisions are gifts of technology. Since Watt invented the steam engine, the whole world has entered the era of science and technology. Since Edison invented the electric light, we have left the darkness and worshipped technology more; Newton discovered the law of gravity because an apple fell from the tree, which made science and technology take a big step forward. Technology is fun, which contains at least several meanings. First, science and technology itself and the natural laws governing the universe are full of charm; Secondly, the process of exploring science and technology and revealing the laws of nature is also very interesting. Third, once science collides with life, there is a relationship between science and technology and human society-both positive, negative and interesting. The branch of academic or vocational research.
Technology is everywhere, and technology makes human beings extremely proud!
How important technology is to us, if one day, without electricity, people will continue to live in darkness; Without gas and oil, wouldn't people want to eat raw things or drill wood to make a fire and continue to pull carts with raw animals? Without mobile phones and computers, do people still use flying pigeons to pass books? ...
From this perspective, we can't live without the contribution of science and technology all the time. I believe everyone around us is exploring and contributing to the development of science and technology in their own way ... Although I am naughty, I really experienced the taste of technology: I put some baking soda powder in the quilt and then added white vinegar, and then the volcano erupted! Suddenly, white vinegar emerged.
With the rapid development of science and technology, science not only serves the cutting-edge technology, but also penetrates into our daily life more and more, which requires us to love and learn science in our youth. I participated in the provincial science and technology innovation and invention competition and won the second prize. He also participated in the municipal science and technology innovation and invention competition and won the third prize. These achievements are inseparable from the hard work of teachers. Participating in science and technology competitions and reading science and technology books have made me understand a lot. Precise robots, cars without fuel, virtual football matches, high-tech information transmission, and so on, vivid and interesting phenomena have aroused my desire to explore science more and more. Each of us should study science, spread civilization and create a new life while enjoying life. Nowadays, the technology products are updated faster and faster, and video TV, computer surfing and pacemakers are not new. From the vacuum cleaner invented by 190 1 to artificial earth satellites and manned spacecraft, science and technology have shown great power in different fields. With the popularization of electronic industry and communication technology, and the wide application of nanotechnology and superconducting materials, bioengineered foods such as space green peppers and artificial steaks will appear on your table in the near future. Studying science and technology is not only to become a scientist and adapt to life, but more importantly, to become the master of the new century, to undertake the new century and to make contributions to national construction and human civilization.
Since the founding of New China, China has made rapid progress in science and technology, such as synthesizing insulin, replanting severed hands, hybrid rice, exploding atomic bombs and hydrogen bombs, and launching satellites and spaceships. These remarkable scientific and technological achievements have greatly shortened the gap between China and advanced countries and injected vitality into China's modernization drive. Grandpa Deng Xiaoping said that "science and technology are the primary productive forces". Indeed, science has given wings to the take-off of our motherland. President Mao Zedong once told young people that the world is your and ours, but in the final analysis, the world is your. This sentence is full of the ardent expectations of our elders. If the elders of the 20th century built the motherland with hard work, then we should shoulder the burden of the new century with knowledge and science.
