Technology changes the composition of life

Science and technology change the composition of life 1 with the development of human civilization and the progress of modern science and technology, in the 2 1 century, various scientific and technological products appeared around us. These products have greatly changed human life and made our life more colorful.

Take the TV set as an example. Now every household has at least one TV set. But in the beginning, our ancestors didn't have it. They can only spread information by consulting books and asking each other. Sometimes, even news spreads from one mouth to ten, from ten to one hundred, from one hundred to one thousand ... and it's easy to get wrong information! However, with TV now, we can achieve "it is well known that a scholar stays at home". How convenient! You can not only learn about major events and small feelings at home and abroad, but also learn about the rule of law, human geography and "model of the times", watch Chinese poetry conferences to cultivate sentiment and compete with players. You can watch cartoons occasionally to relax. ...

There are still some places that modern technology can't reach, such as swimming at the seaside, and lifeguards who drown can't find them in time. We can develop scientific robots, and if we find drowning, we can signal the lifeguards in time.

For example, some people often frown, and they can develop a kind of "laughing powder", which will be very happy to eat in their mouths; like ...

In short, I hope that science and technology will be more and more developed and human life will be better and better!

Technology changes life composition 2 What is technology? Science and technology are all around us. Science and technology have changed our lives and completely divorced us from ancient times.

In ancient times, people wore clothes made of grass leaves or animal skins, which were very fragile and almost broke when the branches were scraped. Nowadays, clothes are made of all kinds of fabrics. In the cold winter, people either wear down jackets or cotton-padded jackets. And these clothes are nice, warm and very durable. It's not a problem to wear it for three or five years.

Ancient people didn't know how to use fire, so they could only eat animals with hair and blood. If I can describe them in one word, it is eating birds and blood. In modern times, people use natural gas to cook. If there is too much oil smoke, there will be a range hood to absorb it. If people don't want to cook, they can also order takeout. You can eat whatever you want.

In the past, people lived in thatched cottages, and some poor people's houses were built of mud. Maybe when it rains heavily, the adobe house will collapse. Nowadays, people live in tall buildings, and the houses are all reinforced concrete. It is impossible for wind and rain to damage the house.

In the past, when people went out for a long trip, almost all of them relied on one pair of feet. Some days were better, and animals pulled carts. Now, you can choose any car, train, subway or plane. The trip only takes a few hours.

Technology has changed our lives, and technology has made our lives more convenient.

Science and technology change life composition 3 Science and technology is the sun, then human beings are the earth; Science and technology is rain, then human beings are flowers and plants moistened by rain; Science and technology are the fountain, and human beings are the desert.

Because of technology, people invented the telephone, and they can chat with their relatives in other places at any time, instead of never seeing each other as in ancient times. Grandma said that in her time, it would take several days for a telegram to arrive, which was a waste of time and money.

Now because of science and technology, people invented the train, which used to take a day and a night's journey, but now it can be reached in a few minutes, and it saves time and effort. The world has become a global village. People can go where they want to go, which can broaden their horizons and increase their knowledge. As the saying goes, "Read thousands of books and take Wan Li Road."

Because of science and technology, people invented mobile phones and computers, which can look up information and know more knowledge. When you encounter something you don't understand, you can always take out your mobile phone to check it, so that you can learn more and know more.

Technology, you have given us a lot of help. Technology, please.

Today, compared with hundreds of thousands of years ago, we are supreme, compared with thousands of years ago, we are condescending. From the previous carriage to the present car, train and plane; From kerosene lamps to incandescent lamps; From the old mobile phone to the present mobile phone. These changes affect and change our lives all the time.

Nowadays, smart phones have brought us many benefits: teachers use the software on mobile phones to leave homework for us, check the completion of homework, and communicate with parents about our school in time. Students will not be criticized for not remembering their homework clearly. They can check it at any time by turning on their mobile phones.

At the same time, mobile phones have also solved the problem of people's communication difficulties before. I used to write letters to my family or friends. Some remote places didn't even have post offices. Now you can talk to your family and friends at any time with just one phone call, and you can also video chat.

However, mobile phones have also brought us troubles and harms: mobile games attract primary and secondary school students and even adults all the time. Some forget to study when playing games, some forget to work when playing games, and some even forget to eat, which affects their lives and those of their families. Many children are also nearsighted because they play mobile games for a long time, and some walk to eat and play mobile phones, so they have car accidents.

With the development of science and technology, many things have two sides. If we understand and use them correctly and avoid their bad effects, we can benefit mankind and make life better.

Technology changes life composition 5 "Dad, did you watch TV before?" I asked bored. "Your father used to watch TV when he was a child!" Grandpa replied, "Just like your father didn't watch TV when he was a child. As long as he is acting, he will go to see it regardless of the willy-nilly. " After a while, my mother said, "In the past, only your fifth grandfather had a TV at home. It was still black and white, and the signal was not good. Now the TV is so big for you, but it is still too small. " I was lost in thought at my mother's words: technology has changed so much for more than 30 years. "

I can't help thinking of my hometown. I heard from my father that the roads used to be dirt roads. As long as it rains, it is easy to fall and get hurt. I listened and thought: We are all cement roads now, so it is not easy to fall down when it rains.

In the second grade, I learned to use computers. As long as there is something I don't understand, I will look it up, and there will be many explanations on it. What songs you want to listen to and what TV you want to watch are all in the computer. Like today's TV, just connect to the computer.

One day, I couldn't answer a question, so I went to check the computer. I enter the topic, and then use the mouse to search. There are many ways out. Even the most difficult topic is obviously a piece of cake on a technologically advanced computer.

After decades, when I become a mother, what earth-shaking changes will our lives have? I believe; With the development of science and technology, our motherland will be more prosperous.

Science and technology change life composition 6 "Baby, go downstairs and help mom-"

"Receive express delivery." Mom's words didn't fall, I rushed to say. This is the third time today to help my mother receive the express delivery.

When I opened the parcel, I was pleasantly surprised to find that it turned out to be the Diary of a Laughing Cat that we ordered online yesterday.

"How can it be so fast?" I asked my mother doubtfully.

Mom smiled and said, "This is the charm of high technology. With the continuous development of science and technology, the work originally done by manpower is gradually replaced by artificial intelligence system, and the speed is naturally faster. Like Yiwu and Tianjin, intelligent sorting robots can sort 200,000 packages a day. "

"It's amazing!"

"Not only that." Mom went on to say, "Beijing has begun to try to send express delivery by drone. There will be more miracles in the future! "

"Ding-ding-ding-"The telephone rang. "Receive express delivery!" My mother and I shouted out in unison.

The room echoed with our laughter. High technology makes life better!

With the rapid development of science and technology, our life is more comfortable and convenient. Among them, asking the way gives me the greatest feeling. In the past, when I arrived in a strange city, the roads extending in all directions often made me confused between the southeast and the northwest. I often waste a lot of time by going the wrong way. Now many airports in big cities and high-speed railway station are equipped with Homo sapiens robots. If you get lost, the navigation robot will tell you the direction, and there are many languages to be translated. From then on, it will make your travel more convenient.

There is also the advent of nano-robots, which also reduces the pain of patients in medical treatment. My grandmother used to have a stomachache, but she was afraid of the discomfort caused by gastroscopy. I have been refraining from going to the hospital. Later, my mother told my grandmother that there is a painless gastroscope, which is a nano-robot, as small as a small pill. My grandmother swallowed it at once, and the little robot diagnosed the cause of my grandmother's stomachache under the operation of the doctor. Grandma didn't feel bad at all. She fell asleep backwards all the way. It's amazing!

The development of science and technology in China is really fast! I really hope that one day, human beings can develop the medicine of immortality and let the family live together forever.

On Saturday afternoon, I went to the movies with my parents and watched a 4D movie. The content of this film is very wonderful and the special effects are very realistic. Something pops up on the screen from time to time, sometimes the chair keeps shaking and occasionally water is sprayed. Compared with those black-and-white movies my grandparents saw fifty or sixty years ago, they are really much more wonderful. In just 50 or 60 years, from black-and-white movies to 4D movies, you said that technology is developing rapidly now!

I'll tell you something, too. There are already driverless buses in Shanghai. Think about it. It's difficult to ensure the safety of everyone on the bus, but is China's invention of driverless bus very powerful?

At home, mom and dad can just bring a mobile phone when they go out, and they can always get discounts when they go out for consumption; Get married and go out? Take a few bank cards with you, because every family will not be skilled in operating Alipay. As for grandpa? He always carries enough cash in his bag and will only pay for everything in cash. You see, in our family, different people enjoy different degrees of convenience brought by technology.

Since it is so developed now, what will happen in the future? I guess, in the future, express delivery will not be sent. Maybe you will press an aircraft on the courier, let the courier fly to the door, make a knocking sound, and someone will open the door.

Technology can bring us a convenient life, but if you don't study hard and can't effectively grasp the convenience brought by technology, you will be eliminated by society.

Technology has changed life, from the previous steam engine to the present train, from the previous postal service to the present e-mail. From the previous bamboo slips to the present white paper. From kerosene lamps to electric lights. Yes, technology has changed our lives.

I read a story. The content of the story is that during the wartime, on the Mid-Autumn Festival on August 15th, everyone wanted to eat moon cakes, and Zhu Yuanzhang was about to rebel at that time, but because soldiers searched there every day, the content could not be delivered to everyone in time. So it thought of a good way, put the note in the moon cake and distributed it to every soldier, so that every soldier knew when to rebel. I was thinking that communication would be more convenient if there was an internet.

Now people can contact others with just one phone call, which is convenient for both themselves and others. Therefore, the network is beneficial to us.

However, if we watch mobile phones too much, it will not only be bad for our eyes, but also make us addicted to mobile phones and eventually become dependent. A person plays games in the internet bar all day. One day, he was playing a game. As a result, he lost the game and died suddenly. This consequence is very serious, which makes us think deeply.

Science and technology have changed our lives, but we must use science and technology correctly in order to have a happy and beautiful life.

Science and technology change life composition 10 Now our life is very good. What do we rely on? It depends on the technology. Science and technology have greatly changed our lives. How come?

Let's talk about the internet first. When there is no internet, people need to rummage through everything to find information. Since Tibernes-Lee invented the Internet in 1960, people's welfare has come. Now it's not as troublesome as it used to be, just a few keystrokes and a click of the mouse, and the information will be found immediately.

Let's talk about cars. Everyone remembers Wang Wei's "Send Yuan 20 An Xi". Wang Wei bid farewell to Yuan Eryi who was going to Anxi in Weicheng. It only takes one and a half days at most to drive from Weicheng to Anxi. If there had been a car, Wang Wei would have seen his old friends again in three days at most except Yuan Er's working hours. It can be seen that the traffic is much more developed now.

The telephone was invented by Bell at the end of19th century, which also brought great benefits to our life. The ancients used the mythical clairvoyance to pin their good wishes, but now clairvoyance has become a reality, no longer a myth. In Romance of the Three Kingdoms, Liu Bei was defeated because he did not deliver the letter in time. If there was a telephone, Liu Bei might not be defeated.

Baird invented television in the early 20th century. In the past, without TV, people used to rely on newspapers to spread news. If the newspaper is sold out, you can't see the news. Now, you can see the news immediately by pressing the remote control in your hand, and TV can also be used for entertainment.

Science and technology change life composition 1 1 in the first grade, the teacher taught us about money-"yuan, jiao and fen", which have different values. It is really interesting! Since then, I have been pestering my parents to ask how much something like this costs. Later, I was not satisfied with just asking, but really wanted to buy it myself.

On this day, my father will take me to buy stationery. I thought to myself, I'll pay the bill myself in the future. Finally, I got to the cashier. "Dad, I want to pay!" ""Don't take money, just use WeChat directly! "Dad refused." Hum! "I'm curious," what the hell is going on? "Dad told me that since the popularity of WeChat, developers have introduced the payment function in this software, so that everyone can shop anytime and anywhere with their mobile phones! But I don't understand. At this time, Dad used his mobile phone to open WeChat to take a picture of the QR code provided by the merchant, and then entered a few numbers. The mobile phone showed that the payment was successful! I stared at all this and felt a little incredible, so I paid for it? I can't help but admire the ingenuity of the inventor of WeChat, and I wish I could invent some interesting software in the future!

Mobile phones can not only make shopping easy, but also have many functions. Like a magic wand!

Science and technology change life composition 12 in ancient times, bonfires were used to transmit information, but now computers and mobile phones are used. Ancient science and technology were very backward, but with the changes of the times, science and technology became more and more developed, which brought a lot of convenience to people's lives.

Let's talk about computers first! Computers can contact others as long as they log in to QQ, and they can also talk face to face with others by video. There are many kinds of games in the computer, and some puzzle games can entertain people's body and mind. Now online shopping has become a direct way for families with computers to buy daily necessities, snacks, clothing accessories, flowers and plants. The first way to play music and movies is on the computer.

Look! Computers bring people a lot of happiness, not to mention other technologies. Air conditioning has become a must-have item in summer. Today's summer is more unusual and hotter, so air conditioning brings people cool, and people spend summer like spring.

Now the medical technology is also superb, and some intractable diseases can be treated.

Modern science and technology are still developing in a good direction. I believe that the future world will be more exciting and people's lives will be happier.

Science and technology change life composition 13 with the rapid development of modern science and technology, I wonder what changes science and technology have brought to us. After coming home from school, I consulted 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 can also broadcast TV signals. ...

Humans have also invented many things that are useful to humans: telephones, computers, televisions ... these things are convenient for people to do some things. Just like a telephone: even if two people are far apart, they can hear each other's voice and communicate with each other within a few minutes by picking up the receiver and dialing a few numbers. Telephone is not enough. Humans have invented computers that are better than telephones. Mobile phones can only hear each other's voice, while computers can communicate with each other in words or video conversations and see each other. If you have a holiday, send an email and the other party will receive it in a few seconds, which can save paper and let others receive it soon ... 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, which will make our human life more convenient and serve us at any time. Therefore, we should study hard and serve the society well in the future.

Science and technology change life composition 14 science and technology are all around us, which not only brings changes to people's lives, but also brings us more convenience.

Before there were no cameras, people could only keep some beautiful scenery in their minds, but they could not record some scenery with pictures. Now every household has a camera, and going out is the best companion. When there is no computer, people may need to look through many books to find the answer. With computers, people can quickly find the information they want ... technology has brought us great convenience.

I like watching "I love inventions" on the science and education channel, which is full of scientific inventions. What is fresh in my memory is that "hawthorn seeder". It doesn't look good. There are many small tubes on a circular turntable, below which are corresponding holes for inserting hawthorn, and there is an outlet for collecting hawthorn. Turn on the power supply, and the turntable for putting hawthorn begins to rotate. When the hawthorn is aimed at the small tube, the tube will be pressed down, the core will be taken out, and the hawthorn will continue to move forward and fall into the box. Because the rotating speed of the machine is very fast, the speed of coring is much faster than that of manual work, which greatly saves time.

Seeing the invention of "Hawthorn Seeder" made me think that science and technology can only serve our lives if we love to use our brains and are willing to study hard. How many scientists have invented something useful to us because of their diligence, curiosity and good thinking.

It is true that technology has changed our lives. It is technology that makes our life better and makes us happier!

Science and technology change life composition 15 science and technology have changed our lives and improved our quality of life a lot!

Speaking of technology, his contribution is really not small! I'll tell you if you don't believe me!

I want to drink a cup of yogurt to quench my thirst in summer, but I am too lazy to go out when I see the scorching sun outside, but I really want to drink yogurt. What should I do? Haha, you don't have to go out for yogurt now. Yogurt machine is our good helper! Just prepare some materials and then put them into 6 small cups of yogurt machine evenly according to the ratio of pure white yogurt 100g+ sugar 70g+ milk 1000g, and cover them; Put them into the yogurt machine one by one and cover them; The setting time is 4~5 hours. After completion, it will be as smooth as a mirror and as successful as tofu brain; Immediately after completion, refrigerate for more than 6~ 12 hours to further purify the yogurt. Do it in the morning and eat it at night.

Set aside a small cup of yogurt for the next introduction; Mix with your favorite jam or seasonal fruit, and then ice it, it tastes better! How convenient? How did the convenient yogurt machine come from? That's right. Now we can have such a convenient yogurt machine because of technology. Of course, I am just giving an example. Science and technology have made great contributions! For example: the current ice cream machine, online shopping, induction cooker, microwave oven, telephone, computer, TV, Internet … keep talking! Technology is changing our lives, and we can never live without it!
