"Thinking is the most beautiful flower on the earth", and the spirit of exploration is the most brilliant. For thousands of years, human beings have been expanding their understanding of magnificent nature, wonderful science and human beings with their tireless spirit of exploration. In the endless exploration of the unknown, mankind has built a colorful and fascinating world. British philosopher Popper once said: "Scientific progress is a mixed blessing. This is a philosophical metaphor. Looking back at the development history of human society, we can clearly see that the reason why we can create more wealth in one century than at any other time in history is that our scientific research always brings good news. Without the progress of science and technology, we can't get rid of the poverty and backwardness of agricultural society; Without the progress of science and technology, there would be no industrial revolution again and again; Without the progress of science and technology, there would be no electronic age and colorful and comfortable life. However, the development of things has its duality, that is, the so-called "misfortune, happiness and misfortune." " 」
The development of science and technology has promoted the progress of mankind, and it is the development of science and technology that has given mankind this brand-new and beautiful life. Throughout the ages, which dynasty and generation did not attach importance to the development of science and technology? Looking back, the four great inventions are unique; Look at the astronomical calendar and marvel; Look at Zhaozhou Arch Bridge, which is beautifully designed; A glimpse of the oriental masterpiece compendium of materia medica: look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue and white porcelain is very famous overseas. Scientific and technological development is the road to a strong country and the first driving force for the progress of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can you eat hybrid 2? How can I put on cotton-padded jacket and live in a tall building?
We are happy, we are lucky, and we have caught up with an era of rapid development of science and technology, an era full of high technology. This is not only because our ancestors chose development and progress in evolution, but also includes the unremitting efforts and hard study of all people. How many hard-working scientists have bought it with their wisdom and even their lives today.
Life is so comfortable, life is so pleasant and life is so wonderful. Our average life expectancy is 30 years higher than that in ancient times, and we don't even have to go out to visit relatives and friends. Isn't this all the benefits of scientific development?
While human beings are developing high technology, relatively, it has also brought great impact to the environment, biology and the earth. For example, Taiwan Province Province has changed from an agricultural society to an industrial society. Because of human industrial activities, the exhaust gas in the earth's atmosphere is increasing, and the greenhouse effect and acid rain are becoming more and more serious, leading to ecological problems such as river and lake biological death, building corrosion and global warming. In addition, although organ transplantation has saved many lives, the society has paid a huge medical cost, and there are also many bad phenomena, such as buying and selling organs, cloning technology, etc ... And how to strike a balance between scientific and technological development and human well-being in the future is a very important topic facing mankind now.
In a word, science is hard and honest labor, which enlightens people's wisdom and cultivates people's spirit of hard work and seeking truth and being pragmatic. Science is to explore and create the future and cultivate people's grand mind, broad vision, courage to explore and innovate; Science is developed in the struggle against fallacies, which cultivates people's fearless courage to pursue and defend the truth without fear of difficulties and setbacks. Science is the common wealth of mankind. It is incompatible with all opportunistic, mercenary and selfish behaviors. It cultivates people's noble sentiments and dedication.
Science and technology change history, and knowledge changes destiny. We have entered the 2 1 century, an era full of high technology. Science has changed our lives, and science has changed our destiny. "Knowledge is power". Why do we, the people of China, a vast country with a population of 65.438+0.3 billion, stand tall in front of the world? Because our technology is constantly developing! Our technology is constantly improving!

How amazing the development of science and technology is now, and the living standard of human beings is also improving step by step. However, when New China was just founded, China's heavy industry was very backward, and its science and technology were not very developed, so it was in urgent need of a large number of economic, scientific, cultural and educational talents. But at that time, China was an oil-poor country. In addition, American scientists have concluded that China has no oil reserves underground. Just when everyone was desperate, one person said: Science has proved that China is rich in oil and natural gas resources. He is Li Siguang, an outstanding geologist in China. It is said that after the birth of People's Republic of China (PRC), Li Siguang returned to the embrace of the motherland in the spring of 1950, and joined the China * * * Production Party in 1958. Subsequently, Daqing Oilfield with large scale and high output was proved, and China got rid of the label of "oil-poor country", which made the world sit up and take notice.
Geologist Li Siguang got rid of the label of "oil-poor country" for China, and Yuan Longping contributed to the complete set of hybrid rice seed production technology in China.
From 65438 to 0973, Grandpa Yuan Longping cultivated and developed a set of hybrid rice seed production techniques. After Grandpa Yuan Longping developed hybrid rice, many international organizations hired him to work abroad with high salaries, but he declined politely: "My roots are in China, and my goal is not only to feed the whole country, but also to eat well." Grandpa Yuan Longping often said, "You can't be a scientist if you don't love your country."
There are many talents in our country. It is precisely because of these talents that our country can be rich and strong. However, these talents can only stand up after layers of tests and hard training; In the field of science and technology in China, these people, as pioneers, wrote their own glorious side and became the founders of science and technology in China. 1964, the first device in China exploded successfully. 1970, the "Dongfang-1" artificial earth satellite was successfully launched. These examples are enough to prove that science and technology in China are developing rapidly. I think as a student in the 2 1 century, we should study hard and strive to make greater contributions to our motherland.

Can science and technology really make the economy more developed and people's living standards more affluent? This is a very serious question, which is not easy to answer. Deng Xiaoping, our great national leader, said that "science and technology are the primary productive forces", which shows the importance of science and technology. However, some people say that technology is a double-edged sword, which has both positive and negative aspects.
To give some concrete examples, countless scientific and technological achievements have been made since the first industrial revolution. For example, Watt invented the steam engine in the first scientific and technological revolution, gradually abandoned human labor, greatly improved the labor force and entered age of steam for the second time.
Edison invented the electric light in the second scientific and technological revolution, which was a great milestone in the utilization of electricity by human beings. Since then, age of steam has entered the era of electricity. The third scientific and technological revolution invented a series of high-tech products such as computers and mobile phones. The appearance of these products marks that we have entered the information age, which is the largest and most far-reaching scientific and technological revolution in human history. The three scientific and technological revolutions have brought unparalleled "historical heritage" to mankind, and also promoted the development of labor force, the continuous progress of production technology, the continuous improvement of workers' quality and skills, and the continuous improvement of labor means, thus improving labor productivity and making human life more colorful.
However, we can't just see its advantages and ignore its disadvantages. As far as its disadvantages are concerned, it can destroy all mankind. High-tech products used in World War I and World War II, such as airships, airplanes, gas bombs, tanks and long-range artillery, have caused great harm to mankind. About 65 million people participated in the war, and 1 million people lost their lives. Many of them died from this technology. In World War II, more than 1 100 million soldiers participated in the war, about 90 million soldiers and civilians were killed or injured, and 30 million people were displaced. All this is brought by technology.
So we say that technology has two sides. You can't judge by its surface.
