Technology changes life, combined with family writing.

1. Composition of technology changing life 1. Times are changing and science is progressing. With the development of science and technology, computers are gradually entering our lives, and the network has now become an indispensable tool in life, such as chatting, surfing the Internet and studying ... However, the appearance of computers has brought changes to people's lives.

Pupils seldom study online, but mostly play games and chat. This kind of example is not uncommon. It is with the advent of computers that there are all kinds of examples.

Technology changes life. Although technology has made our life more comfortable, have they seen the deterioration of the environment? The air is getting more and more turbid, people can no longer breathe fresh air, and it seldom snows in winter. Don't you know?

Technology has not only changed our lives, but animals are also doomed. The turbidity of the air makes animals unable to survive, and the harsh environment makes most animals on the verge of extinction.

Technology changes life, and I hope that one day technology can really "change life".

I have a good habit since I was a child. Every time I finish the homework assigned by my teachers and parents, I will run to the study and sit in a chair and watch "100,000 Why" with relish. It will last for hours, and every scientific truth is deeply imprinted in my mind. At the dinner table, I will also tell my parents all the new knowledge I have seen, so that I not only know a lot of knowledge, but also enhance my expression ability.

I have another feature-I love to ask why. "Why is the sky blue?" "Why is the sea salty?" "Why did dinosaurs become extinct?" ..... Dad can't understand why there are so many "whys" in my little head. There are too many small question marks, and some of them stumped the teacher's father. At this time, I will look for the answer in the book. If I can't find it, I'll look for it in a big bookstore. In short, I must find them.

When I was a child, my dream was to be a scientist, and I wanted to invent something for everyone that is not in life but helpful to human life. But what's the use of just talking and not practicing and dreaming? So I went to participate in many scientific and technological activities to enhance my understanding of scientific and technological knowledge. You know, a successful scientist started at an early age. He is not a natural scientist. He must practice and imagine boldly, and he must persist and work hard. And while doing scientific and technological activities, I also learned to persist, learn to work hard, and learn to ask teachers and adults questions that I don't understand.

We are no strangers to science and technology, because we live in the embrace of science and technology every day and enjoy the convenience and speed brought by science and technology every day. Maybe you haven't found it yet, maybe you will question: "Technology? Where is the technology? " You see, technology is around you: TV, computer, mobile phone, mp3 player, rocket, satellite, spaceship ... and so on. I can't talk for days and nights. In a word, life is inseparable from technology, and technology serves life. Bit by bit, always doing everything, technology is everywhere.

When Watt invented the steam engine, the whole world made a sensation. Today, it is not surprising that we are sitting on the high light rail and high-speed subway. When an apple fell on Newton's head from the tree, the clever Newton discovered the gravity of the earth and invented many things according to its law. How hard scientists have made from discovery to invention!

Science and technology are developing rapidly, and life is trying to change. Science and technology are changing our lives. We live in an era of rapid development of science and technology. We should be proud, we should be proud!

Science is a key to innovation, and it can only be opened if it is mastered reasonably.

Humans are looking forward to the birth of another scientific and technological invention, which will make our life better!

With the development of science and technology, the quality of human life has taken a big step forward. From the previous carriage to the car, from the previous oil lamp to the electric light, communication has been accelerated by telephone, the pace of life has been accelerated by car, and delicious meals have been cooked by rice cookers. ...

Science has changed our way of life, and every scientific and technological progress has brought great changes to our lives. The display of science and technology makes people's lives more convenient, fast and comfortable. For example: computers. Nowadays, with the development of science and technology, computers have entered thousands of households. Generally divided into two categories; One is personal computers, including desktop computers, notebook computers, and the latest is tablet computers. The other is a supercomputer, with an operation speed of over 65,438+0,000,000 times per second, which is mainly used in banking, scientific research and military affairs. A computer consists of a hardware system and a software system. The hardware system of a computer is mainly composed of a host, a monitor, a keyboard, a mouse, a speaker and a camera. The mainframe is the head of the computer, just like our brain, which controls the daily work of the computer. The monitor is like our eyes, showing us the results of all the work. There are 26 English letter keys, direction keys, numeric keys and several important keys on the keyboard, which is the main input device of the computer.

Computers allow us to see the world without leaving home, so "high-tech" fluorine-free inverter air conditioners can be low-carbon and environmentally friendly. The so-called "fluorine-free" is actually the use of refrigerants in the ozone layer that do not destroy the atmosphere. Frequency conversion is to change (reduce) the power supply rate, solve the problem that the unstable voltage of the power grid affects the work of electrical appliances, and make the room temperature lower than a constant temperature set by users.

With the development of science and technology, we have to face a series of environmental problems. I hope there will be a fuel cell car in my future life. It is a new type of environment-friendly car with clean fuel and no harmful gas emission. From the aspects of energy utilization and environmental protection, fuel cell vehicle is an ideal pollution-free vehicle. Its efficient, energy-saving and zero-emission environment can reduce air pollution.

As long as we believe in science and study science, there will be better high technology in the future, so that we can live a better intelligent life!

Help me write a composition that technology has changed my life. Thank you, classmates, when we sit in front of the TV and watch colorful programs; When we press the mouse to swim in the computer world; When we are immersed in chatting happily with our classmates on the phone ... Have you ever wondered: What has brought so many changes to our lives? It is technology, the great power of technology, that has changed everything around us and changed the whole world!

With the gradual development of science and technology, what changes have taken place in our lives?

Dad said: our work has become easy! It's no longer like grandpa's time-working day and night with his back to the loess and eating by the unpredictable and moody God. In the high-tech agricultural greenhouse, the climate is warm all year round. When the grain is ripe, many tiring procedures such as plowing, sowing and harvesting can be managed by computers and completed by agricultural instruments. So technology has pulled people out of heavy physical labor.

Mother said: now our life is getting better! Yes, people used to worry about not having enough to eat and not sleeping well. But now, no matter what the problem is, as long as the technology comes out, all the problems will be solved! We are not only full of rice baskets, but also full of vegetable baskets, which are more nutritious and richer than before! Last year, my father installed an air conditioner in my room. Even in hot summer, I can't read in my small room.

If you ask me, I think technology has made the world smaller, and computers are the most important category. On the Internet, I have made good friends with many strangers through QQ, and I can talk to them if I have any troubles. The development of science and technology is not limited to these. I think that the Tang Priest went to India to learn the scriptures, waded all the way, slept in the wind, went through hardships and walked for several years before reaching his destination. Now, comfortable and safe means of transportation, such as cars, ships and planes, have left our footprints in almost all parts of the earth. This National Day, my father and I also went to the World Expo!

In the East of the New World, our ancestors invented gunpowder, compass, printing and papermaking, creating their own glorious history. We are fortunate to grow up in a brand-new era. The flower of science and technology has never been so brilliant, and the road of science and technology has never been so broad. Students, let's cultivate and carry forward akg's good habit of thinking and creating from childhood, and create our happy and beautiful home for love! Spend it on your mother.

4. Technology changes life. Modern science and technology are developing so fast. I want to know what changes technology has brought to us. When I came home from school, I asked my father.

Dad said that technology has brought too many changes to people. Like the invention of the compass, it promoted the development of navigation and trade, completed the great geographical discovery, and made mankind know the earth; The scientific and technological achievements of hybrid rice and super rice have increased grain output and solved the problem of feeding the world population; Satellites provide us with satellite cloud pictures and weather forecasts, and also relay TV signals ... Humans have also invented many useful things for human beings: telephones, computers, televisions ... which make it convenient for people to do some things.

Just like a telephone: even if two people are far apart, just pick up the receiver and dial a few numbers, and you can hear each other's voice and communicate with each other in a few minutes. It is not enough to have a telephone. Man has invented a computer that is better than telephone. The phone can only hear the voice of the other party, and the computer can communicate by text or video conversation, and you can see the other party.

If there is a holiday, send an email and the other party will receive it in a few seconds, which can not only save paper, but also let others receive it quickly ... The development of science and technology has improved our living standards and quality of life! In the new century, science and technology will develop faster, make our human life more convenient and serve us at all times. So we should study hard and serve the society well in the future.

5. Technology changes life as the theme. Daily life has also been changed by technology.

With the rapid development of modern science and technology, we have stepped out of the previous era of eating raw food and drinking blood and come to an era of advanced technology. The development of science and technology has brought great convenience to our life.

I used to worry that there would be no lights at night, but every household is brightly lit tonight; It used to be luxurious to taste the delicious food in the sea, but now fish and shrimp are commonplace; In the past, I always found it difficult to deliver letters from home, but now, heaven is still our neighbor ... yes, a series of benefits brought by science can not be ignored!

In the Tang Dynasty, Yang Guifei wanted to eat fresh litchi, but fresh litchi could only be eaten in the south, so the emperor sent someone to transport it from thousands of miles away with a fast horse. How many fast horses have been exhausted to ensure freshness! But nowadays, it is common for ordinary people to eat fresh litchi everywhere in the market. It can be seen that the development of science and technology has brought us much convenience!

In ancient times, homeless people missed their relatives in their hometown very much because they lived and worked far away from their hometown for a long time. After writing home letters, their families didn't reply ... why? Because the letter may have been lost halfway before it was delivered home; It is also possible that it took a long time for the family to receive the letter, and it may take a month or two for the wanderer to receive the reply from the family. So it is difficult to say a word to his distant relatives.

Now, you can send messages to your family far away, which is very fast. In less than a second, the other person can know what you want to say, not only the conversation, but also the video chat. In this way, you can chat with distant relatives at any time and see what they look like. How happy it would be if you ever met your relatives in the distance! Technology can help you solve things that people can't. For example, if you encounter difficulties in learning, as long as you turn on the computer to type, the correct sentence will be displayed on the computer display screen. As long as there is science, there is no need to worry about any major difficulties.

However, with the development of science and technology, environmental problems have been ignored. Discharging wastewater into rivers on a large scale makes people unable to eat safe seafood and wastes valuable resources on a large scale, but never thought about how serious the consequences will be. While developing science and technology, we should also protect the environment.

Science and technology is a double-edged sword, which is the driving force of our human progress. It has brought us convenience and development, but it has also brought many negative effects. We should make full use of the benefits brought by science and technology, and we can't ignore the environment on which we live.

6. Composition: Technology changes life (500 words) Three compositions [1] Technology changes life At present, technology is more and more developed, and people are gradually entering the information age. Now let me introduce one of the iconic items in the information age-mobile phone. Small and exquisite appearance, very light. It has many functions, such as sending messages, taking photos, checking calendars and so on. It is also the most commonly used way to send messages and make phone calls quickly. In ancient times, it took several days or more for people to meet and send messages. And writing letters, you are in Dongcheng, I am in Xicheng, and it sometimes takes ten days, half a month or even months to send me letters from Dongcheng. What a long wait! However, since I got a mobile phone, my life has changed. If there is an emergency, don't worry. Just send a message and the other party will receive it in a few seconds. If you want to meet somewhere, just call. How fast! Let's save a lot of time. Of course, mobile phones don't represent all technologies. Nowadays, the Internet, artificial communication satellites and so on all make human life more comfortable and convenient. In short, technology has greatly changed our lives. [2] Science and technology have changed my life. With the development of global science and technology, our life is getting richer and richer. The development of these technologies has changed our lives. The maglev train does not run close to the rail, but runs on the rail surface in the form of suspension. It turns out that it uses the principle of electromagnetic induction to attract and repel to make the train body float, and then uses solar energy, wind power or water power to drive the train. This kind of train will not be very noisy. Will not pollute the ecological environment. In Japan, the car body is suspended by the magnetic field induced by electromagnet and coil. In Birmingham, England, the train is suspended by the magnetic field between electromagnetism and track. Cement mixers transport mud, and loose mud blocks are used in the construction site. In order to prevent the mud from caking, it rolls as it walks. There is a large sports transport vehicle, also a round box, which is used to transport liquids. The circular design of liquid tanker is reasonable. The round tank has no edges and corners and is not easy to be damaged. The pressure on the circular tank is relatively uniform. Satellites are high-tech communication buildings, which are launched every few years. The satellite consists of stars, transponders, receiving and transmitting antennas, solar power supply system, attitude control and orbit control system. We see TV programs thousands of miles away receiving wars from satellite antennas to various regions. Some auxiliary equipment will be provided separately. In this way, we can watch TV programs thousands of miles away. High-rise buildings are very common in cities, so we have to use them because of the high land price. There are various shapes of high-rise buildings, such as square columns, circles and prisms. Common zigzag buildings, like rectangular building blocks, have poor wind resistance. Cylindrical buildings have better wind resistance. The famous cylindrical building is the Peach Tree Central Plaza Hotel in Atlanta, USA, which is the tallest conical hotel in the world. Conical buildings have the best wind resistance and strong earthquake resistance. Science and technology are changing our lives and leading us into a brand-new society. As long as we love science, study science and observe science, we can create a perfect realm! [3] Technology changes life. Times are changing and science is progressing. With the development of science and technology, computers are slowly entering our lives. Network has now become an indispensable tool in life, such as chatting, surfing the Internet and studying ... However, the appearance of computers has brought changes to people's lives. Pupils seldom study online and spend most of their time playing games. Chat This kind of example is not uncommon.

8. Technology changes life composition 400 words fifth grade "Technology changes life" composition: What kind of life has technology brought us? I still remember those farmers' uncles who bent over in the hot sun, sometimes they didn't get much money for a month, but now? Who are those people who are sitting on the recliner and leisurely looking at their farms with a cup of tea in their hands? Or a farmer's uncle. The axe and sickle of the past have now become plows; Cattle used to be farmed, but now they are gone; The once desolate fields are now golden. In the big tent, all kinds of fruits and vegetables occupy the land. Even the humble cottage of the farmer's uncle has become a villa. What makes us so happy and satisfied? It is technology. You must have seen Journey to the West! The Tang Priest in The Journey to the West and his three apprentices finally came to Leiyin Temple. If it is now, they can choose any means of transportation, such as cars, trains, planes, and Shenzhou VII, which has just gone to heaven. They can go anywhere they want and even take us to another planet. Do you know that?/You know what? Digital home and electronic life have appeared in our lives. Whenever and wherever, you can surf the Internet, listen to music, watch movies and send emails easily with a small mobile phone. What brings us so much convenience? It is technology. Imagine what our life would be like without computers, mobile phones and broadband. We use mobile phones to contact our parents and let them know their location and feel at ease. We also go online to participate in online meetings, where children from all over the country can discuss the same topic together; We look up information on the internet, supplement our extracurricular knowledge and understand current events. Isn't it enough to watch the 2008 Olympic Games on TV? Don't worry, you can watch it online, anytime, anywhere, whatever you want! What brings us such a wonderful and rich life? It is technology that has changed our lives and changed the world. I think how lucky we are now, living in such a technologically advanced world, we should study harder, and the future development of science and technology depends on us to create.

With the development of science and technology, the quality of human life has taken a big step forward. From the previous carriage to the car, from the previous oil lamp to the electric light, communication has been accelerated by telephone, the pace of life has been accelerated by car, and delicious meals have been cooked by rice cookers ... Science has changed our way of life, and every scientific and technological progress has brought great changes to our lives, making it easier and faster for science and technology to show people's lives. One is personal computer, including desktop computer, notebook computer, and the latest one is tablet computer.
