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!

The word technology is familiar to everyone. Simply put, technology is technology. In a broad sense, it refers to the sum of natural science and technology and social science and technology.
Since the reform and opening up, with the passage of time, science and technology have mushroomed in the motherland. Looking around life, technology is everywhere, and technology is by my side!
Walking on the road at night, there are electric lights to illuminate us; Call a friend and take out your mobile phone at your fingertips; Back home, turn on the TV to watch the news, turn on the computer and chat with friends; Mother steamed rice with a rice cooker; Turn on the electric heater; The whole family is sitting around, enjoying the delicious food prepared by my mother with an electric wok ... Do you think we can leave technology anytime and anywhere?
Technology is very useful! For example, if there is no electric car, it will be inconvenient for us to communicate with distant relatives and friends; If there is no EMU, it will be difficult for people to travel everywhere. Without the space shuttle, it would be empty talk for people to go into space; If there were no icebreakers, it would be difficult for us to go to Antarctica. Without space instruments, it would be just an illusion for humans to land on the moon. ...
On the contrary, with technology, our life will be better-with fax, our documents can be easily sent out in an instant! With robots, you can be in a space that people can't reach; Using laser, you can make fitness equipment; With air conditioning, people can feel as comfortable as spring even in hot summer. ...
It is not difficult to see: all this, people enjoy the achievements of science and technology!
This shows that technology has helped us create a superior living environment; Science and technology have improved our quality of life; Technology is the crystallization of the wisdom of people all over the world!
We are engaged in technology, and we should constantly learn new technologies!
Science and technology are around us, and we must vigorously develop science and technology!

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 bring extinction to 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. 20,000,000 people were injured, and many of them died under this technology. In World War II, more than 1 100 million people 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.
