Ask for hand copied newspaper information about scientific and technological progress and a better

Looking at history, from printing to papermaking, from word processors to the sharing of online information, human intelligence has been deepened, which is the driving force of humanity; From the perspective of human spiritual value, science and technology have freed people from the shroud of poverty, and the Internet science and technology information has brought the fourth wave of thinking about democracy and human rights, and physiologically from antibiotics to organ transplantation, from water conservancy irrigation to the improvement of biological varieties, have alleviated the crises of mankind again and again, and when the development of science and technology has brought about the deepening, broadening and optimization of people's physiological, psychological and spiritual values, can it be said that the development of science and technology has inhibited the all-round development of people

The most direct embodiment is medical treatment, we are now a healthy person standing here, of course, we can say without hesitation that scientific development is harmful, because it destroys the environment, so that the earth is loaded with a lot of unnecessary things, but those patients who are struggling in pain, because there is no scientific development, there are no more advanced medical measures, in the face of them, can we still say that environmental protection first? Is life important or environmental protection important......

Now, most of the use of special mining technology, will be unscathed, assuming that in the past, with artificial technology, then a piece of ** and about fifty or sixty percent of the part will be wasted, if there is no scientific and technological development, will waste so much property.

In the past, people's technology was not so developed, and trains were powered by coal, which polluted the air.

Examples of how technology changes lives:

1. Technology has changed the way we communicate.

There are many devices today that are made possible by other technological advancements that are very important in everyday life. Most people have PCs, tablets, and smartphones that can easily communicate across different platforms. In the past, you had to write a letter to communicate with someone.

The letter may even take a few days to be delivered. You also have to keep track of the letter to see if it has been sent and received by the appropriate person. Mistakes are also not uncommon.

However, there is no such phenomenon today that science and technology have established this. If you want to communicate with someone in society, all you have to do is message or call them on social.

<>2, technology has changed how we pay our bills and move money.

Companies like PayPal have created a platform where people can send and receive money from any location using the internet.

Paying bills has also been simplified due to technology. You don't have to carry cash with you when shopping. Using mobile phones and banking apps, you can** complete all the necessary bill payments.

<>3, technology has reduced the amount of labor we have to do.

In family life, housework is a task that every family is completing in the division of labor, but now that science and technology are becoming more and more developed, many small machines have been invented that can make it easier for us to complete housework, refrigerators, washing machines, these are common household appliances.

Sweeping robot,Small and cute,Not only can clean the corners of the hygiene,And it is controlled by artificial intelligence,You can give instructions on your mobile phone,And it will intelligently avoid obstacles, etc.,It is a good helper for home life。

4. Travel mode, efficient and fast transportation.

Due to the development of science and technology, we have become more and more convenient to travel, and the gradual popularization of high-speed rail, subway and so on. Increasingly developed means of transport are faster and more convenient in terms of transportation. In the past, it could take days and nights to travel from south to north, but because the new transportation time has been greatly shortened, many express transportation industries have also been born.

The role of science and technology.

1. Social progress.

The productive forces developed by science and technology have created a highly developed material civilization, but the improper use of science and technology has caused extremely serious environmental problems around the world.

2. Economic development.

China's labor productivity is only 1,40 of that of developed countries. Once science and technology are transformed into productive forces, they will greatly improve production efficiency and thus promote rapid economic development, and their role greatly exceeds the role of capital and labor in transforming the economy.

With the exception of the great Newton and the great Einstein, no one has made such a great contribution to the progress of mankind as he did. Even Newton and Albert Einstein drew wisdom and inspiration from him. He is "the ideal embodiment of a theoretical genius and an experimental genius in one", and he is the scientist Archimedes whom I admire the most.

Today, I'm going to tell you the story of Archimedes.

Archimedes, was born in a small village near Syracuse, Greece. He was born into a noble family and came from a very wealthy family. Archimedes' father was an astronomer and mathematician, a man of great learning and humility.

Influenced by his family, Archimedes developed a keen interest in mathematics, astronomy, and especially geometry in ancient Greece from an early age. Archimedes was brilliant from an early age, and coupled with his diligence and studiousness, he stood out from his peers from an early age.

Cars, planes, and trains make it easy to get around.

The secret of the towel hardening --- a soft Mao Ming towel, which will become dry and hard after a long time. It turns out that in our domestic water, there are many minerals dissolved. The water that contains more calcium and salt in its rubber type is called hard water.

When the main ingredient in the soap used for washing the face is dissolved in water, it will combine with calcium and other ingredients to form a water-insoluble precipitate. However, if you boil a stiff towel in vinegared water, the sediment will fall off and the towel will soften again.

When I add my mailbox, I indicate, QQ talks.

.Why do the stars twinkle and twinkle?

We see the stars shining, not because of a change in the luminosity of the stars themselves, but because of the occlusion of the atmosphere.

The atmosphere is separated from us and the stars, and when starlight passes through the atmosphere, it is affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency varies depending on the density. So if we look at the stars through it on the ground, we will see that the stars seem to be flickering.

2.Why do people yawn?

When we feel tired, our body already produces a lot of carbon dioxide. When there is too much carbon dioxide, oxygen must be added to balance the body's needs. Because this residual carbon dioxide will affect the functional activities of our body, then the body will send out a protective response, so we yawn.

3.Why do snakes walk without legs?

Snakes have a lot of scales on their bodies, which are the outermost layer of armor on their bodies. The scales are used not only to protect the body, but also to their feet.

When the snake crawls forward, its body will be in an S shape. And each scale, on the outside of the S-shape, will be warped to help the snake grasp the uneven road surface as it advances. These scales work with the snake's muscles and propel its body forward, so the snake can move around without legs!

4.Why sunflowers always bloom towards the sun?

The place under the stem of the sunflower flower disc contains a substance called auxin. This substance has the function of speeding up reproduction, but it has the ability to resist rotation, and whenever it encounters light, it will run to the backlit side.

So when the sun rises, the sunflower stems immediately hide on the backlit side, and it looks like the whole plant is bent in the direction of the sun.

5.Why do people turn gray when they get old?

There is a substance called melanin in our hair, and the more melanin there is, the darker the color of the hair. If there is less melanin, the hair will turn yellow or white. When human beings reach old age, various body functions will gradually decline, and the formation of pigment will become less and less, so the hair will gradually turn gray!

You can first write about the benefits that high technology has brought to us, and then use the comparison between the past and the present, and write about what you want to contribute to the motherland.

Life is so comfortable, life is so comfortable, life is so wonderful, our average life expectancy has increased by 30 years compared with ancient times, and we don't even have to leave the house to visit relatives and friends. Look at the present, solar water heaters, solar air conditioners, solar cells, ......Environmentally friendly and energy-saving solar energy has gradually entered thousands of households, isn't this the development of science and technology?

Another example is what we can do:

Let's make an eco-friendly tip:

1.Buy simple packaged goods, buy green products, green food, and advocate green consumption;

2.Reduce the use of disposable products (wooden chopsticks, paper cups, paper towels, etc.), reduce garbage, and carry out garbage classification.

3.Use energy-saving electrical appliances, and completely turn off the power after the electrical appliances are used to save electricity; moderate use of air conditioning;

4.Ride more bicycles and buses more to contribute to energy conservation and emission reduction;

5.Reuse paper, print on both sides, send more e-cards and e-mails, protect forests;

6.Get close to nature, participate in afforestation activities, adopt (donate) a tree, place your ideals on you, and bury your wishes.

7.At home, keep a few more pots of flowers.

8. Care for green life, protect the greening achievements around us, widely carry out the civilization activities of "planting, protecting, loving and rejuvenating", and strive to be the messenger of green civilization, so that the sky of our home is bluer, the water is clearer, and the land is greener.
