Science and technology make life better excellent composition material 1
The land under our feet is undergoing earth-shaking changes all the time, all of which come from technology!
A thousand years ago, people lived a simple and hard life. At that time. People don't understand what the spiritual world is, just want to be safe, eat and drink enough and maintain a normal life. To this end, people burn incense and worship Buddha and pray for peace. Carriage should be the only means of transportation, but it is expensive, so people have to choose to walk. It's a long journey from Shanghai to Beijing. If you have pneumonia, there is no cure, so people's life span is very short.
Now someone has invented the mobile phone, which has eased the lovesickness and melancholy of people in different places; Someone invented the plane and gave up the long journey of people running around outside; Someone invented an anesthetic to prevent people with this disease from suffering another layer of pain. It is technology that makes our earth smaller and smaller. At this moment, we are no longer satisfied with material enjoyment, but more at ease in spirit. Burning incense and worshipping Buddha still exists. What doesn't exist is people's stupid ideas.
The medical technology developed at present can cure almost all common diseases in life, and the extended people have more time to expand and enjoy life. The rapid development of natural science and technology such as biology and chemistry has brought rich and colorful spiritual food to people who were originally curious. While exploring and inventing, human beings affirmed their self-worth, while enjoying the benefits brought by science and technology, they also gained joy.
In the past, people marveled at the stars in the sky; Today, we have been able to send satellites into space.
In the past, people thought about how to gain a foothold in this law of the jungle world; Nowadays, we are thinking about how to survive in this infighting world.
In this society, we need to face up to the power of science and technology, so as to make our life more perfect!

Before the invention of the telephone, who believed that people could talk freely thousands of miles away? When there is no high-speed rail, who believes that a few days and nights will become 2-3 hours? Before the invention of electric light, who believed that you could see clearly without your fingers at night? Today, with the development of science and technology, this is entirely possible.
In ancient times, people made a living by eating meat and hunting large animals with sharp stones, and gradually got grains. At that time, harvesting by manpower had a low survival rate. Decades later, human beings increased grain production and gradually became omnivores. I don't know how many years have passed, and humans have learned to mine minerals and refine them into various utensils and weapons at high temperatures. Invented the combination of meat and vegetables. After experiments, it is more convenient to hunt with a gun.
In the past, the only way to travel was to walk. If you really don't want to go, take your beloved donkey and travel around the world slowly! Of course, in today's society, there is no such thing as riding an animal on the main road. Therefore, laziness forces people to use their brains and hands, such as carriages, bicycles, electric cars and cars.
With cars, people have a new problem, traffic jam! So, the "bar spirit" thinks, does anyone stipulate that driving on land is necessary? Can't I fly freely like a bird? Can't you swim happily in the water like a fish? Scientists were the first people to take part in this dangerous experiment.
With the changes of the times, we have all kinds of planes; There are countless ferries; All kinds of cars ... and public transportation such as subway and bus make life more convenient.
Technology drives life and makes life better!

We can't live without high technology every day, such as the mobile phone we use every day, the high-speed train we take, the 3D movies we watch and WeChat payment. Technology makes our life richer and more convenient.
If you don't understand high technology now, you can't move a step. For example, one summer vacation, I went back to my hometown to play, and my sister and grandmother went to Zhengzhou's largest complex to play. Grandma was curious all the way, how to scan the QR code by car, and the subway can travel underground. You can use your mobile phone when you pay, and ask how to use it all the way. We all patiently explained to him one by one, and he would smile and nod. After playing for a few days, grandma remembered a lot, learned to pay by mobile phone, and took the subway alone. Although grandma is 70 years old, she can go to many places by subway and use many high-tech things. She is happy, and we are happy for her.
Even when we went back to our hometown for the New Year this year, grandpa said that cooking can be reserved by mobile phone and TV can be voice-controlled. It's time to eat from one city to another. Our domestic big plane soars in the blue sky of the motherland, and we will be able to travel all over the country by our own plane; "Space One" has realized the connection between heaven and earth, and space life is no longer a fantasy; It is no longer difficult to "talk" with aliens; The "Dragon" has already gone deep into the seabed to spy on the mysterious world of the ocean.
"Just a classmate and teenager, in full bloom." We are undoubtedly a lucky generation, because our technology is more and more developed, and we need the power of science and technology to explore mysteries, pursue truth and create miracles. Technology makes our life better.

With the development of the times and the improvement of science and technology. People's travel has become more convenient and the distance between people has become closer.
In ancient times, people used carriages as a tool for traveling. Although the carriage can be richly decorated, it is still very bumpy in the process of driving. In ancient times, there was a bloody BMW that traveled thousands of miles every day and was often fascinated by people. But it seems to be slow now. With the birth of the first car of 1886, land transportation has entered the era of rapid development, which has narrowed the distance between cities. In ancient times, it was estimated that it would take one month for people to travel from Zhengzhou to Beijing, but now it only takes 6-8 hours by car. 1903, the Wright brothers built the first plane, and people's travel made a qualitative leap, flying from land to the sky. Aircraft is not only the representative of rapid traffic, but also the embodiment of a country's military science and technology! In ancient times, it took more than a few years for Zhang Qian to go to the Western Regions, but now it only takes a few hours by plane. The development of science and technology makes our transportation more convenient and promotes the vigorous development of tourism and logistics.
Technology not only makes transportation more convenient, but also makes our communication more intelligent. Our communication first started with bonfires, evolved into letters, then to fixed lines, and now to mobile phones. In ancient times, letters were the main ones, and sometimes they were delivered within a month. With the telephone, you can talk in real time even thousands of miles away, not only in real time, but also for video call, data transmission, voice input, online payment and so on. Now you can get everything done with your mobile phone when you go out. You can brush your mobile phone, take the bus, buy clothes, watch movies, pay utilities or brush your mobile phone. These are all technologies created by human beings, and we use technology to feel the beauty of technology!
With the rapid development of science and technology and the continuous improvement of people's living standards, people's demand for science and technology is also increasing. Technology is accompanied by life, which facilitates our travel and life. This makes us sigh that technology makes life better.

Science and technology is a sweet spring in the desert, nourishing my dry heart; Technology is a boat that takes us into the turbulent sea; Science and technology is a galloping horse, taking us across the endless prairie.
Now you can buy what you need without going out; You can read online without books; You can find all the information you need without tools.
One day, when doing exercises in the information class, let's use the Xinhua dictionary of the browser to check how to pronounce this word. We need to open the browser, check the Xinhua dictionary, check the radicals in the Xinhua dictionary, and find the factory prefix of the two paintings. When we look up the prefix "Factory", the dog and a painted in No.9 Middle School will jump out of the pronunciation and meaning of the word "Yan". Another problem lies in the National Digital Library of China.
When there is no electric light, people usually do it at sunrise and rest at sunset, which conforms to the laws of nature and life. However, people's work and rest are limited by nature. Later, our great inventor Edison invented the electric light after thousands of experiments. Since the invention of electric light, it has illuminated the whole world and brought hope to people in the dark. Now, there are small light bulbs all over the street, small light bulbs are hung at home, and lights are also placed in the cars of every household to illuminate us.
With the development of science and technology, it has changed the beautiful life of each of us, making it more convenient and comfortable for each of us to travel and order food.

Now every family has a TV, and TV is the representative of technology. Grandpa likes watching plays, sitting in front of the TV and watching singing inside. Dad likes to watch legal programs and military programs, and he knows about state affairs every day. I like watching variety shows. As long as I have time, I watch running bars and other variety shows on TV. Of course, only one TV will have some conflicts. Dad was watching his favorite "National Affairs", when my variety show began again. What should I do? Then I will go to the computer.
Computers are also essential. Now the country has given the teacher a computer for work, and my parents also have one. They are teachers. Dad can like playing games on the computer, and mom likes watching TV series on the computer. But when my parents watch TV, I ask about playing computer. Computers can download games and play games that can be opened immediately.
Mobile phones are also essential. Now everyone has their own mobile phone. It's convenient to use a mobile phone. It used to take at least a month to deliver letters in ancient times. What about the mobile phone now? A message only takes a few milliseconds. You can use it to make phone calls, look up dictionaries, watch videos and read e-books. In the past, "looking up, I found it was moonlight, and then sinking, and I suddenly thought of home." Now, WeChat and QQ, a video call can solve the missing of relatives thousands of miles apart. Now with the high-speed train, it takes only two hours to get to Beijing and a few minutes to get to Kaifeng. Riding alone in China is not a dream. This is the full power of technology.
I want to study. In the future, many more convenient things will be developed to benefit the people and contribute to the country. Technology makes life better.

With the continuous development of the times and the growing strength of the motherland, our life has become more convenient with the development of science and technology.
On the morning of National Day, my mother and I went shopping in the supermarket. Just arrived at the gate of the supermarket, an uncle pushed a shopping cart for me. The appearance of this shopping cart is the same as the previous shopping cart. The only difference is that an electronic screen is added to the handle. There is a scanner beside the electronic screen, and a scale is added under the shopping cart where things are put. My uncle asked me to find my favorite goods. Scan the QR code of the item on the scanner next to the electronic screen and put it in the shopping cart. After listening to my uncle's introduction of this new shopping cart, I can't wait to go shopping. I want to try this shopping cart. I found my favorite biscuit, found out his QR code, scanned it aside, and the product was displayed on the screen. Then I weighed it in the shopping cart and bought a product.
Finally, after shopping, there are three ways to pay. When you scan the QR code generated by it with your mobile phone, the payment is completed. Looking at the entrance of the supermarket, there are not only manual payments, but also independent payments, which can be paid in the shopping cart. I also want to give it a try when I see independent payment. I took a product and walked over. It also scans the product first and then weighs it. Now I think it is exactly the same as that car.
I used to go to the supermarket to buy things. God, when I checked out, there was a long queue at every checkout. Manual payment is particularly slow. Sometimes I spend an hour shopping and half an hour checking out, but people find it very troublesome, which not only wastes time, but also makes my good mood disperse in a hubbub. Compared with now, it is a world of difference.
Technology makes people's lives more convenient and beautiful.
