Speeches on the development of science and technology, speeches on the prosperity of science and tec

China has gradually stepped onto the world stage, and its international influence in the field of science and technology is also increasing. Chang'e-4, Long March-5, Xuelong-2, and Beidou navigation are all important technologies for winning the battle against poverty.

However, students, we must be clear that although our country has made a lot of scientific and technological achievements, there is still a lot of work to be done compared with our goal of building a world science and technology power.

Science and technology are the primary productive forces. Social productivity is people's ability to transform nature, and Naixun, as a natural science of human beings' ability to understand nature and transform nature, is inevitably included in social productivity. Once science and technology are thoroughly involved and cooperatively applied to the production process, they become real, direct productivity.

Over the past 70 years since the founding of the People's Republic of China, along with the economic take-off, China's scientific and technological progress has never stopped. China's road of scientific and technological innovation is an extraordinary road full of thorns and bumps, tears and sweat.

High-temperature superconductivity is one of the most cutting-edge research fields in the world, the world's superconductivity research began in the early 20th century, and China's superconductivity research started late, probably around the 50s of the 20th century. Superconductivity research will have a great impact on many important fields such as scientific research, information and communication, industrial processing personnel, energy savings, transportation, biomedicine and even aerospace, and has broad application prospects.

That's the end of my remarks, and thank you for listening.

Technology makes our lives easier, and convenient and fast machines are produced by us, making our industrial assembly lines more practical. At the same time, technology has also led us to the universe and allowed us to explore other planets. Science and technology have made the sound transmission of thousands of miles an ordinary thing, making our transportation more convenient, and science and technology have promoted the development of the times and innovated the world.

But technology has its drawbacks that are difficult to overcome. Although the machine is convenient, but it requires electricity, and now, how many power plants have to discharge countless tons of exhaust gas and waste residue every day, which greatly destroys the ozone layer and endangers our safety all the time. Although there are automobiles, most of the exhaust gases emitted every year come from them, and at the same time, tens of thousands of petroleum and diesel fuel are burned, and these precious resources of the earth are decreasing every day.

At the same time, countless trees are cut down every year, and many are used for processing, burning. Let's take a look at gunpowder, one of the four great inventions of ancient China, what is it used for now? Aren't bombs, bullets, shells, mass destruction** and fireworks used in our New Year's party made of gunpowder?

So what do we get in exchange? Cannibalism, air pollution, indiscriminate killing of innocents, wouldn't we be better off without these things?

And, now there is smog, how did this smog come about? How many people die from respiratory diseases every year? Died of lung cancer?

Now, technology can no longer deal with our number one enemy, but makes the smog worse, so isn't technology a big disadvantage?

While technology may benefit us entirely in the future, it will definitely do more harm than good now!

As long as the disadvantages are minimized and the benefits are maximized, it will be fine.

Do you believe that the benefits of technology outweigh the disadvantages? Anyway, I believe it
