With computers, people can quickly find the information they want ... technology has brought us great convenience. The following is an excellent composition I brought to you. I hope I can help you.
Science and technology change life excellent composition 1 science and technology is the guarantee of human happy life. If a nation is not developed in science and technology, it will fall behind. Now technology has entered thousands of households, whether it is a bustling metropolis or a simple small village, it has a strong "scientific and technological flavor."
Last summer vacation, I came to the place I always dreamed of-the capital Beijing. According to my mother, technology was underdeveloped and transportation was inconvenient. It used to take more than ten hours to get to Beijing by train, but now it takes two hours by plane. Yes, there was no high-speed rail and civil aviation before, which can be described as "unable to move". In recent years, with the rapid development of science and technology, railways spread all over the country, airplanes flew all over the world, and the earth became a "global village". "Traveling thousands of miles a day" and "walking in clouds and fog" are no longer myths.
Shopping every day, people also spend a lot of time trying to "be lazy again." When people turn paper money into electronic money, they only need to deposit it in Alipay, a "mobile banking", so that they can avoid the trouble of changing the change. The current vegetable market is no longer the environment where the money counter rings in haste, but the word "successful payment" is ringing. Now, instead of counting money from the wallet in a hurry and sweating profusely, the grocer "goes into battle lightly", picks up the mobile phone, scans the QR code, pays the money, picks up the food and leaves the vegetable market at a brisk pace. Today's vegetable lady is not like before. She gave change in her left hand and loaded vegetables in her right hand. She was in a hurry. Instead, she packed the dishes, sat leisurely in a rocking chair and played with her mobile phone, waiting for the sound of "successful payment". With Alipay, people's lives are more convenient, time is more abundant, people's pace of life is gradually faster, and life is more fulfilling.
The mobile phone is a versatile person, which can be used not only as an "electronic bank" but also as a "clairvoyant" and "clairvoyant". If you miss someone now, you don't have to go to the post office to post a letter. Just open WeChat directly, send voice and text, and in one second, my relatives far away from home will receive your greetings. If you want to chat face to face with the person you love, show more concern, open a video chat and solve the problem for a few seconds. This brings people closer together, making the earth truly a "global village", bringing people closer together and making the world look smaller.
Now, human beings are making continuous progress, and science and technology are constantly improving human life. Let's study hard and make a contribution to human progress when we grow up!
I was curious when I saw my mother crouching under the sink in the morning, so I ran over and asked, "What are you doing, Mom?" Mother said, "The water pipe in the sink is blocked again. Even if the filter screen is placed on it, it will still be blocked. It doesn't matter. They are all old. " "Then why not buy one? How tired it is to squat like this every day! " I asked doubtfully. Mom replied, "Even if you buy another one, it will be useless, and it will still be blocked." Just like the house next door to Xiangxiang, his sewer is blocked. I just bought one two days ago, and yesterday, it was blocked again. "It pains me to watch my mother squat and dredge the pipeline every day.
So, I want to invent a turbo water tank. There is no need to worry about blocking this sink. Because even if you pour leftovers in, you won't. Because there is a filter in that hole, this filter is not like other filters. It will divide the incoming things into two categories, one is liquid and the other is solid. It can put two things in different places. So that solids don't enter the sewer. Where did the solid go? It's simple. The two buckets matched with this sink are specially used to put solids. You don't have to dredge it like that every day, just lift it up and dump it every day.
The so-called turbine means that the water in the ordinary sink goes down very slowly, and this turbine is installed on this sink! You will suck the water in the sink into the hole and suck it quickly. Don't worry that the sink is full of water and won't overflow. Moreover, this device does not need electricity, that is to say, it is environmentally friendly and pressurized, and its pressure will not break, so there is generally no big problem. But the most important thing is that it is very cheap, and people with any family conditions can afford it, so this thing will be used by every family and is very affordable.
After listening to my advice, my mother was very pleased and thought I was very imaginative and thoughtful.
Technology changes life. The light at night is the reflection of the lamp. The coolness of the hot summer is the melody of air conditioners and electric fans; The circulation of the world is the transmission of networks.
In my spare time, I eat melon seeds, turn on the air conditioner and watch the computer. I rubbed melon seeds all over the floor. When parents come in, they always forget to say, "Now you are having a good time. You don't have to do anything. " I didn't say anything, but I knew it: "Ancient people wore straw sandals. Why don't you wear them? You always compare modernity with your time. " When I think of this sentence, there are always many associations in my heart: How did people come over before? Nothing. You have to drill wood to make a fire. Aren't you tired? Where do they get bath water in winter? Did they drill wood to make a fire? Alas! Well, then they don't have any high-tech products. Isn't it hand-woven clothes, alas! Think about how happy we are now. Everything is replaced by machines. Ha, except that there is no machine to replace the brain. If there are all kinds of machines in the future, shouldn't I just sleep in bed and wait for the robot to turn on the air conditioner and computer for me and make money for housework? Am I lazy, so infatuated? But if there is, that would be great. Maybe one day, you see, robots are getting more and more developed year by year. Maybe there will be robots that can replace all our actions and human beings in the future! Technology is endless, full of color, full of happiness and happiness. Gratitude for science and technology, even a thousand words, can not be expressed. Junior high school students' science and technology change life composition
Science and technology is the ladder of human progress; Science and technology is the trajectory of human growth; Technology is the eternal essence of human beings. If technology is a piece of jade buried in the ground, then humans will dig you out; If technology is a meteor in the sky, then humans will chase you; If technology is a bright moon in the night sky, then humans will come to pick you up. I believe that in a very short period of time, human beings will definitely dig technology out of the surface and trace it to the end. Because science and technology are the relaxed society and happy society that human beings dream of. Human beings have lofty aspirations, unshakable determination and perseverance, and look forward to a bright future. Science and technology have changed human life, endowed the world with color, and made our life full of vitality, vigor and motivation. It makes our life wonderful. Technology has changed our lives!
With the changes of the times, the strength of the country and the development of science and technology. The word "technology" is becoming more and more frequent around us. It has become the most indispensable part of our life. In the past, mobile phones could only make phone calls, but now they can not only make phone calls, but also shop online, play games, take photos and so on. Computers and mobile phones will appear in most people's homes, and even some people can't live without them at all. Now, as long as you stay at home, you can buy things on the shopping platform at home. It can also be turned into a learning tool immediately. It is also a multifunctional game machine. It also has a great ability-even in a far place, it can become close at hand, and it can let you see the person you want to see immediately.
Because computers and mobile phones have become indispensable things in life, I have gradually fallen in love with them.
Once, inadvertently, I added my sister's WeChat and talked a lot with her on WeChat. On New Year's Day, she gave me a few dollars in red envelopes. In that society, it is impossible to transfer money and send red envelopes with a small mobile phone. This skill can only be realized by modern technology. One day, my dad said to me, "Didn't you add my sister's WeChat? You tell her I miss my mother-in-law and let him open the video. I want to talk to her mother-in-law! " So, I opened the WeChat video. We are here and they are there. There seems to be only a screen between us. The man opposite seems to be framed in the screen. I saw my father and mother-in-law chatting happily. I also thank technology! It gives everyone
Family brings infinite joy and happiness! The distance between people is getting closer, and the feelings between people are harmonious! Science and technology have been developing, and it is the development of science and technology that gives us a brand-new and beautiful life!
"Technology" is an indispensable thing in life, and everyone cannot do without it. Science and technology have changed history and entered an era full of high technology. That's because we are making progress! Constantly changing!
Technology changes life. Technology changes life, and the upgrading of technology makes me full of infinite curiosity about it. Finally, I am looking forward to this day, because I will visit the Shanghai Science and Technology Museum with many young journalists from our school. With excitement and excitement, we talked and laughed in the car, and even the raindrops beating on the window were singing cheerful songs.
After three and a half hours' drive, we finally arrived at our destination. As soon as we entered the museum, the first thing that caught our eye was various animal models: an African elephant with a long nose sticking up high seemed to welcome us warmly; Wolves prey on antelopes; Giraffes eat leaves with relish. ...
Then we came to the Spider House, where we were introduced to the appearance, habits and living environment of various spiders. What impressed me most was the bird-eating spider. Bird-eating spider is the largest spider in the world. It has thick and long hairs on its body and thighs. According to scientists' research, such long hair can help it feel the slight vibration of the outside world. Once the prey sticks to the spider web, the bird-eating spider will quickly find it, hold it with its two front legs, and then bite it with its poisonous mouth, and the prey will be poisoned, so that it can enjoy a good meal slowly. The toxin of the bird-eating spider can easily paralyze the bird and become its food. Do you think it's awesome?
Come to the second floor, there is our favorite "robot world". The first people who greeted us were two Rubik's Cube robots. No matter how messy I beat the Rubik's cube, it only needs to look at it for a few tens of seconds, and then turn it with its flexible mechanical arm a few times, and it can be restored to the same color on six sides. It only takes more than a minute at the earliest, which really amazes me. And "Gobang Robot". I didn't believe it could beat me at first, so I got away with it. Unexpectedly, I lost. How clever this robot is!
This trip to the Science and Technology Museum is not only interesting, but also broadens our horizons and feels the infinite charm of nature and technology, which really benefits us a lot!
