Presumably, everyone has heard of 3d printers some time ago. It can not only "print" a complete building, but also be used in many fields such as jewelry, footwear, industrial design, architecture, engineering construction, automobile, aerospace, dentistry and medical industry, education, geographic information system, civil engineering and so on. Its working principle is: put data and raw materials into a 3d printer, and the machine will make products layer by layer according to the program. Printed products can be used immediately. With it, you can not only eat delicious food, put on appropriate clothes and live in a comfortable room. This is a smart life brought by high technology.
If you think this is a little far from our life, then you must have heard of intelligent robots! Nowadays, intelligent robots are really varied and omnipotent! The laundry, cooking, singing and dancing that we humans can do are just a piece of cake for them; The dirty work in the factory still stumbles them; What people can't do, they will also go to the deep sea for treasure hunting and go to the desert to play. Make endless contributions to our lives.
Of course, those high technologies are a little abstruse for us primary school students. Only by studying more knowledge hard can we better create a better life with our wisdom. In fact, I think environmental protection is also an intelligent life. We should make rational use of limited resources to create our life. For example, the paper we use every day can be written on the reverse side after writing. When a book is almost finished, you can leave the remaining pages as drafts. I once saw a public service advertisement: one tree after another was cut down to make a book, but someone bought a book and threw it away after turning a few pages; Some people throw away a few pages in their notebooks, which leads to excessive felling of trees, calling on us to take action to protect vegetation.
Save paper and water! Although we are not short of water in Ningbo, the drought some time ago still makes us nervous. I am eager to see the news in the evening paper every day. Fortunately, there was a typhoon to alleviate our drought. You know, there are many children living in drought in this world. They are not so lucky as we are, and they can't drink clean water every day.
If you think, how can these be regarded as intelligent life? Then I think you are wrong. If we can't even do the most basic things in life well, we can't talk about a smart life. We should start from the details and start our own intelligent life.
Dragging my parents to go shopping on weekends, I always feel something is wrong after going out. Hey, why didn't dad bring his wallet today? How can I go shopping? What should I do if I am hungry?
As soon as I entered the mall, my mother went shopping to "boost domestic demand" and excitedly began to choose clothes. Half an hour later, my father paid the price for my mother's success. I hurried over, curious to see what my father would do without a wallet. "Is the wallet hidden in your pocket?" Secretly, I guess. I saw my father take out his mobile phone, skillfully aim the camera of the mobile phone at a black-and-white pattern on the counter, and the mobile phone jingled, then input the amount on the screen and click OK. In just a few seconds, my father settled the money and watched the process intently. I was so surprised that my jaw almost fell off.
When I walked out of the store, I couldn't wait to shake hands with my father and ask what was going on. My father explained, "This is called code scanning payment, which is the world-leading cashless payment consumption in China. The black and white pattern you see is called QR code, which represents the unique identification information of each store. Payment can be made as long as it is confirmed by scanning the payment software. With it, you don't have to bring your wallet when you go out now, which is more convenient and faster, and you don't have to worry about losing your wallet. " Oh, I see! I suddenly realized that I couldn't help but marvel. After that, we watched movies and tasted delicious food until we took a taxi home. We spent a wonderful weekend paying by scanning code.
Not only has scanning code payment become a common scene in life, but four new inventions, such as enjoying bicycle, scanning code payment, high-speed rail and online shopping, are in the ascendant, and new technologies are changing with each passing day, constantly entering and changing our lives: Is it inconvenient to go to work and travel? It doesn't matter, take out your mobile phone, sweep it, enjoy your bike, let's go on the road easily and avoid fatigue along the way. Is it too far to visit relatives? It doesn't matter, buy a high-speed rail ticket online and take a nap. The comfortable high-speed rail will send us to our destination quickly. Is it troublesome to bargain shopping? It doesn't matter. When we open Taobao, we can see novel and fresh items from all over the world for us to choose from. After clicking the mouse easily, they will be delivered to our door, bringing us warmth and happiness. ...
Once, these situations were just distant dreams; Nowadays, technology has entered thousands of households and changed our lives! In the future, our budding seeds will become the new pillars of the country, and more scientific and technological inventions will be born in our hands, making life happier and the motherland stronger. We are so confident!
Wisdom Life Composition 3 Life is full of wisdom. Luban was cut by sharp grass when he was a child. After several days of thinking, he invented the saw. In this way, the efficiency of woodworking is greatly improved. I also learned the wisdom of life from playing chess and climbing mountains.
I fell in love with playing chess under the guidance of my father. Today, I want to have a big fight with my father. I lost patience in the first game. I was completely confused by his tactics against my father, the sworn enemy. He took turns to attack with cars, horses and guns, but I was eager to defend, so I could only be blocked and watched my chess pieces be "eaten", so I lost the game.
From this game, I understand that if we only pay attention to defense, it will bring great benefits to our opponent, and he will continue to use various means to cause all our "fierce generals" to die because of protecting the "general". And don't worry at every step, you must go through careful consideration, otherwise it will lead to a great increase in mortality. Losing a game has greatly reduced confidence. I can never cope with his various means. Of course, I don't have to guess the final result.
In playing chess, I realized: I am too inferior, which makes me play chess in the wrong way, and so is life. If you leave a shadow after failure and become inferior, you will be afraid of doing things in the future. Only if you believe that you can, will you have a chance of success.
After losing two sets in a row, I was a little depressed. I asked my father to take me to climb the mountain, because I really can't play anymore.
Of course, for a small man like me, climbing mountains will be a little tired. It was a long time before my father reached the top of the mountain, and I followed him slowly. There are many thorns all the way, and I have nothing to borrow, but there is a steep hillside below, and it will definitely smash if it falls. I sat and rested, panting, thinking: If I don't make a decision soon, I may be stuck here tonight. I have no way out, I can only try my best to conquer this mountain.
I groped slowly, dug a hole in the soil with the surrounding stones, and trampled some weeds that hindered me step by step. Finally reached the top of the mountain, the road was wide and the sunset was beautiful in the distance. Ha ha! I finally overcame the difficulty and climbed up.
Wisdom does not care for lazy people, but only for diligent people. Life is like playing chess, you should know how to observe every move and not make a hasty decision. Life is like climbing a mountain. Only when you dare to climb and use your mind can you see the beautiful scenery.
