Technology makes life better. I believe everyone has heard of the word 1. Technology and life are closely related and inseparable. Science and technology can make our life better and more energetic, and also improve our civilization.
Without technology, there is no motivation. In ancient times, the most commonly used means of transportation was horses. In the Tang Dynasty, Yang Guifei liked to eat litchi, which was produced in the south and had to be transported to Xi 'an. We all know that a horse can run dozens of kilometers at most. After running a horse, you have to go to a nearby post office to change a horse before running. This is not only troublesome, but also a few days and nights of running. But now it's the opposite. Now there are planes, trains and cars ... just sit up and it will only take a few hours. It's nothing.
Without technology, there is no light. When it comes to light, everyone will think of two words, and that is electric light. In ancient times, we could only use oil lamps. When we have been using them, we have run out of oil and must refuel. This is not only a waste of oil, but also very troublesome. Think about it, if there is no light, it is like being in endless darkness and enduring darkness and pain forever. The taste is unpleasant. Do you know the story "Sorry"? Kuang Heng poked a hole in someone else's wall just because he was poor and had no light. Later, this problem was solved by Edison until the end of 17. After hundreds of efforts, he finally invented the world's first electric light, and his electric light was on for hundreds of hours! This is really a brilliant achievement!
Without technology, there is no speed. During the Spring and Autumn Period and the Warring States Period, there was a front-line battle report, which not only needed several horses, but also took five days to reach. Even if it is 500 miles urgent, it will take at least 3 days and 3 nights. It's different now. Now, if you want to send a letter, you just need to send it by email on the Internet. Once sent, it only takes a few seconds for the other party to receive it. This is simply a paradise, an underground!
Technology is so important to us! Students study hard, become scientists in the future and make your contributions to the cause of science and technology! I believe that in the near future, our science and technology will be promoted step by step, and our life will be better and better with the development of science and technology.
Technology makes life better. Science and technology, as the name implies, is science and technology. Everyone should be familiar with science and technology, because it is used and served by us and it is closely related to our lives. It not only brings us spiritual pleasure, but also physical comfort. In this rapidly developing society, science and technology represent a kind of spirit as well as a kind of strength. It represents an innovation and a civilization. It is an important symbol to measure a country's comprehensive national strength, and science and technology occupy an important position in any field.
Science and technology are widely used, including military, biological and aerospace. Technology has been integrated into life and enriched it. In the street, at home, in the classroom and in the shop, technology has brought convenience to people. It can be said that human beings created science and technology, and science and technology also created human beings. Human beings and technology are interdependent. Our food, clothing, housing and transportation are inseparable from technology. Let me take you into the wonderful life of science and technology.
Clothes make the man, and everyone needs clothes to dress himself. Take a closer look at the clothes we wear, such as acrylic, silk and pure cotton, which are slim, warm and healthy. They bring us warmth and comfort, health and happiness. These clothes can't be made without technology. Let's say warm clothes can make you feel warm. In the cold winter, we don't have to wear thick down jackets and sweaters, but only a light and soft warm clothes can make us feel warm. You see, isn't this the convenience brought by technology?
Let's see what we eat. Now, we should pay attention to everything we eat, that is health! With the progress of society and the development of human beings, people's concept of food has also changed, not only pursuing delicious food, but also demanding healthy and nutritious food. Nowadays, many people eat high-tech foods, such as protein powder, calcium tablets and dietary fiber. , are studied by scientific and technological personnel. Today, we talk about a high-tech food: vegetable juice drink. Vegetables are an important source of vitamins and minerals and the guarantee of life and health. In terms of nutrition and health care, vegetables can provide comprehensive nutrition and prevent or even treat nutritional deficiency. However, because the taste of vegetables is not accepted by most people, scientists and technicians have improved vegetables and made a delicious vegetable juice drink, which has become an ideal future drink.
Let's take a look at the most common material for building houses-cement. Cement is a brownish gray powder made of limestone and clay. When it is used, it becomes hard and abnormal when mixed with water. In recent years, with the development of new technology, functional cement has been continuously developed. There are many kinds of high-tech cement, such as glass cement, light cement, rubber cement, sugar water cement and color-changing cement. They all have their own characteristics and are the crystallization of science and technology. Today I'm going to introduce you to a magical cement: color-changing cement. This kind of cement is not only an ideal building material, but also can be used to forecast the weather. Also known as "meteorological cement", it is blue when the weather is dry. Once wet, it turns purple; If it rains, it will become a bright rose after absorbing water. It changed color because cobalt dioxide was added to the cement. Look, isn't it amazing? In fact, this is also the surprise and convenience brought by technology.
Speaking of cement, let's talk about cars. The car is a convenient and important means of transportation. Whether traveling or going to work, it is convenient to have a car. Looking back at the history of automobile development,1On July 3rd, 956, the first medium-sized truck named "Jiefang" was born in China, ending the history that China could not make a car. Later, Dongfeng brand domestic cars were produced; The first car 2. 2 tons of military off-road vehicles; First adopt 60 dump trucks; The first coach and the first red flag car, etc. Today, Honda, Mercedes-Benz, BMW ... these are the crystallization of science and technology, releasing the charm of science and technology. It is the development of science and technology that has brought us today's convenient cars. It can be seen that science and technology have made great contributions to us, and everything we have today cannot be separated from science and technology.
Science and technology have played an important role in food, clothing, housing and transportation, facilitating and benefiting mankind.
In the rapidly developing 2 1 century, technology is not mysterious. It is hidden by your side. As long as you observe it carefully, you can also invent your own technology. Perhaps the small technology you invented, after being modified and perfected by experts, has become a veritable scientific and technological product, and can also make great contributions to the future society and mankind.
Students, science and technology is a magical and great cause, which brings infinite joy and convenience to our lives, allowing us to understand, discover and create science and technology. I believe that technology comes from life, and life cannot be separated from technology. Let's use our wise eyes to discover technology!
Technology makes life better. Since some electronic products came out, they have changed our lives. Many high-tech also waved like the world. These high technologies make life better.
Just like mobile phones, we used to want to talk to our distant relatives. You have to write a letter and let the postman run around to deliver it. In the past, people sometimes didn't want to make breakfast, so they bought it. Now people don't need to buy, but can order food on their mobile phones. And the delivery person only needs to run a short distance to deliver it.
And the car. In the past, people had to walk a long way to get to school every day, but now it is completely different from before. Now human beings have invented cars, which can carry people far away and walk without legs at all. Cars are also divided into bicycles, electric cars and cars. Bicycles are pedal-driven, and electric cars are electrically driven. Cars can run as long as they refuel, and they run very fast.
Now the highest technology content is robots. A robot is a machine much like a human being. It can walk and talk. Nowadays, many people have a machine called a cleaning robot at home. This robot can automatically help you clean the floor and keep the desktop clean. This kind of robot is very practical, and some restaurants are also using robots, called home robots. He can help you clean the table, wash the dishes, sweep the floor and mop the floor. It looks like a real person.
How does the present life compare with the previous life? Is it very different? The technology now is really great! It's really technology that changes life! The technology now is really wonderful!
