With the development of science and technology, human civilization has taken a big step forward, from the previous carriage to the car, from the previous oil lamp to the electric light. ...

Now, people's lives are getting better and better. Use the telephone to speed up communication, use cars and motorcycles to speed up the pace of life, and use electric cookers and gas to cook delicious meals. ...

Television is indispensable in life. We can watch the news and learn about things at home and abroad; You can watch cartoons and relax; You can also skip the live shows and performances. For example, the mascot of this Olympic Games has been announced, so you can watch it at home.

Computers are more and more widely used in all walks of life. We sent a letter to Brazil in Lianyungang, and it only took a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world online. You can watch news, movies and listen to music online. You can listen to the teacher in class and find information. You can go shopping, see a doctor and ask for help without leaving home. ...

It can be said that technology is closely related to us. With this advanced technology, our life is faster, more convenient and more colorful.

Is the development of science and technology beneficial or harmful? This is a never-ending problem. Some people say it's harmful, others say it's beneficial. However, my intuition tells me that the development of science and technology is beneficial. Science and technology have been developing for thousands of years, from horse-drawn carriages to cars, trains and planes; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; I used to write letters to people far away, but now I can use my phone or mobile phone. Video chat if you want to meet.

Without the development of science and technology, where would there be such a beautiful life today? Humans have gone from eating raw food to eating cooked food with fire, from carving with stones to writing with pens, from the invention of cold weapons to hot weapons ... Isn't this progress? Isn't this all developing? If the disadvantages outweigh the advantages, then human beings still live in primitive times. Without progress and development, there would be no high-rise buildings and so on. Only progress can make tomorrow better!

Although we are constantly improving and developing, we are also destroying it. Because there is light, there will be darkness. When we see the light in the development of science and technology, darkness will slowly come to us. Take more precautions and make up for what we lost.

You see, after all, the advantages of technological development outweigh the disadvantages.

I remember a saying: technology is a double-edged sword. On the one hand, it can crush ignorance and backwardness, on the other hand, it may bring endless disasters to mankind. At this time, we emphasize the pain and disaster brought by science and technology to mankind, precisely because this double-edged sword can play its positive role in benefiting mankind, not the other way around. The so-called good medicine is good for the disease, because thinking about science and technology rationally and comprehensively can keep science and technology under the control of human beings all the time and will not harm human beings in turn.

In fact, the example is very good: the development of atomic physics theory has enabled mankind to master nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Nagasaki, and brought about a "terrible peace" for mankind for 50 years. For the first time, human beings have the ability of self-destruction. In addition, there are endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous. With the development of chemistry, we have gained unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why are so many children suffering from leukemia in our country now? Very important factors are chemical adhesives used in home decoration and ozone-destroying freon. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too much interference, and the earth began to catch a cold and have a fever. The development of biotechnology has given us the power to create life monopolized by God before, but it has also brought about ethical disorder.

Friends, have you read my article and firmly believe that the disadvantages of technological development outweigh the advantages?

The dream of mankind is always ahead of technology, but no matter how far it goes, it is still a dream. Only when we meet technology can we turn our dreams into reality and bring surprises to people's lives!

The scientific and technological changes in the 20th century have gone far beyond the changes of millions of years, which can be described as "like the strong wind in spring, blowing at night and blowing open the petals of ten thousand pear trees". Let's make a comparison!

Let's talk about traffic first. People used to walk in the past. Children go to school, adults go to work, and there is no transportation. Later, there were bicycles, and then there were motorcycles. Now, with cars, people go out and sit in cars, listening to music, humming songs and sitting in soft parking spaces. How comfortable it is to go where they want to go! Compared with the original, it is really "a world of difference!" Isn't this technology changing life?

First of all, in ancient summer, the ice in the ice room was transported to the palace to relieve the heat. In winter, the ancient heating facilities mainly included fire pits, fire walls, fireplaces and stoves. But now with air conditioning, whether it's hot summer or cold winter, just press the remote control and it's neither too cold nor too hot. Isn't this technology changing life?

Let's talk about it. In the past, our contact information was only letters, and it took several days to go back and forth. At the moment, with a phone and a mobile phone, just dial a few numbers, and in a short time, relatives in Qianshan, thousands of miles away, can talk. It is not enough to have a telephone. Humans invented computers, which can not only hear voices, but also see each other! Isn't this the change brought by technology?

Life is much better now than before, but I believe that life in the future will be a hundred times better than now! We dream that cars can fly in the sky in the future; The house is a tall building with hundreds of stories, which can move and avoid tornadoes and earthquakes. When you get home, there are robots to help you work, cook and so on. You don't have to carry a schoolbag to school in class. Schools are full of e-books, and teachers will no longer use blackboards. Instead, they will have a huge display screen. You don't have to raise your hand to answer the question, just press the button on the table!

You may think this is out of reach, but I believe that as long as we are willing to work hard and dare to explore the mysteries of science, our dreams will definitely come true! Let's fly our dreams together and fight for them!

Now the weather in Yanshan is hot, and carbon dioxide permeates us all day. The environment is getting worse and worse, and drought threatens us. We inkstone people must protect our inkstone mountain. In order to make tomorrow's inkstone more perfect! Stay away from carbon dioxide and walk into a low-carbon life.

In the Expo site, almost all the concepts of "environmental protection" are displayed in the Expo site. Using led energy-saving lamps instead of incandescent bulbs, carbon dioxide emissions are several times less than incandescent bulbs, and technology has enabled us to enter a low-carbon life. Look at the inkstone mountain at the moment, the sound of car horns has made the originally quiet street a mess, and there is car exhaust! Carbon dioxide enters our life again. The transportation made by science and technology makes our life very bad. Just like the previous example. Is technology good or bad for us? Science and technology are both beneficial and harmful to us, so we should make science and technology beneficial to us rather than harmful. Only let science and technology innovate, how to innovate? For example, cars can use electricity to start our cars without burning oil. There is also the ability to ride a bicycle, which is both environmentally friendly and exercise. Computer can prevent it from producing radiation. Radiation is very harmful to our health, and personality is harmful to our eyes.

Light does great harm to us. No matter what kind of lamp, it will emit carbon dioxide. Only led lamps emit less carbon dioxide. When you sleep at night. People are already very tired. At that time, people absorbed the carbon dioxide emitted by the lamp again. The danger is getting closer and closer to us.

More trees should be planted so that they can help us absorb harmful substances, such as carbon dioxide, radiation and sulfur dioxide. But on this day, why do we find fewer and fewer plants around us? That's because someone found an investment project and cut down trees to make furniture. With the money, the danger is closer to us. Can money buy back permanent health?

"Walk into a low-carbon life and let science and technology innovate!" Let's make up our minds to protect our perfect inkstone tomorrow!
