How to write a composition with modern science and technology

1. Looking back, people used few electrical appliances in their lives, only those radios and black-and-white TVs.

Nowadays, with the development of science and technology, every family has at least one color TV, refrigerator, electric light, tape recorder, and some families also have microwave ovens, mobile phones and even computers. There are countless electrical appliances and high technology in the homes of those celebrities! Among so many electrical appliances, I think the most popular one is the computer.

Speaking of computers, many children will say I like them. The reason is that it can play games

Many parents will say that computers delay learning. Actually speaking, computer is a good learning tool.

When you need some information to enrich your knowledge, you don't have to go to the library to read many books, which will waste a lot of time. You can sit in front of the computer and knock on the keyboard, and you will find relevant information in a short time.

This not only saves time, but also ensures that you can successfully complete the task. Not only that, the computer is a good partner for your leisure time.

When you are free, you can sit in front of the computer, play your favorite video games, or log on to the Internet and talk freely with netizens from all over the world. Is this not good? However, many children have no good control. Besides going to school, they spend their spare time playing computer or chatting online.

Many adults are also angry because they are afraid of delaying their children's academic performance. In this way, computers have been condemned by adults, but they are very popular with children.

To this end, many families have paid a huge price. This is the joy and worry brought by modern science and technology. They bring convenience to people, but at the same time they also bring contradictions to people.

Here, I want to tell everyone: "The development of science and technology is to better help the progress of mankind and the development of the country, not to help people kill time. At the same time, I hope that no matter what you do, you must grasp the discretion, don't care too much about its existence, and don't ignore its existence. "

3. How to write a composition with technology?

problem solving

In scientific and technological activities, observation records should be made when observing experimental objects; When conducting experiments, you should write an experimental report; In order to introduce a technology product to others, you should write a product description, etc. These recorded words, which are based on science and technology and made in scientific and technological activities, are called scientific and technological compositions.

Scientific writing is an important content of practical writing at present.

Why practice scientific composition?

This is related to the status of science and technology. Science and technology is the primary productive force, an important driving force for social progress and historical development, and an important factor for the country's prosperity and people's happiness. At present, in order to build socialism with China characteristics as soon as possible, the state is carrying out extensive scientific and technological activities in schools. In primary schools, extracurricular science and technology groups were organized. The "Five Small" activities centered on "small observation, small report, small experiment, small invention and small production" were carried out to cultivate scientific and technological interests and exercise their ability of observation, thinking and hands-on. Therefore, learning to write scientific and technological composition is not only the need of modernization, but also the requirement of school scientific and technological activities, which is consistent with the Chinese teaching task of initially cultivating primary school students' ability to write practical writing. For primary school students, actively participating in the writing of scientific and technological composition can not only have the above advantages, but also systematize and organize the knowledge learned from extracurricular scientific and technological activities and consolidate the achievements of extracurricular scientific and technological activities, which is a multi-faceted thing.

The types of scientific and technological compositions include observation records, experimental reports, investigation reports, production instructions and popular science essays introducing scientific and technological knowledge.

There are many similar requirements for the writing of these articles.

The first is loyalty and reliability.

Science and technology is an honest thing, which requires accurate disclosure of the objective laws of things and one by one test in actual combat. Scientific composition is a true reflection of scientific and technological activities, and it also requires truthfulness and reliability, and it is not allowed to have the slightest fabrication or fabrication, even if it is a very small detail. If a chemical is introduced as non-toxic, it is necessary to repeatedly experiment and analyze various internal components to prove that it is non-toxic.

Secondly, scientific and technological composition must be concise.

The content of scientific and technological composition must be clear, but not too long. In short, simple and clear. Sometimes, in order to achieve the purpose of simplicity, it is necessary to use charts to make people see at a glance. Conciseness is related to words. In any composition introduced to ordinary readers, technical terms should be used as little as possible, because only professional technicians can understand it. Ordinary people don't understand it and use it too much. People who write it feel very clear, and ordinary readers feel unclear and difficult to read.

Third, scientific and technological compositions, such as experimental reports, have their own formats, so we should master the formats before writing, so that the experimental reports and other articles written can meet the specifications. The general format is divided into several items: title, preface, text and ending. The name of the experimental report in the topic should generally be clearly written, such as "climbing the wall experimental report" The purpose, time, object and method of the experiment should be clearly written in the preface.

Fourth, the language of scientific and technological composition should be accurate and concise. Don't pile up adjectives, use words repeatedly to make sentences, and be accurate.

Science and technology and life

Science and technology are everywhere, which makes us feel extremely proud. Our food, clothing, housing and transportation are inseparable from the contribution of science and technology.

Inventions and creations in the 20th century have brought endless changes to mankind. Zipper: seamless; Washing machine: liberating the labor force; Vitamins: make the tree of life evergreen; Rice cooker: uncooked rice is cooked into cooked rice; Air conditioning: There are four seasons like spring here; Cixian floating train: a train that can "fly"; Neon lamp: sleepless pearl ...

Ah! Now the technology is really developed! Even our school has endless science and technology.

In a science class, Mr. Wang gave us a lesson about electricity and magnetism. Teacher Wang told us: "The electric energy in life originated from 1820. In an experiment, Danish scientist Oster accidentally put the electrified wire close to the compass and found that electric energy produces magnetism. Because of this discovery, it opened the door for human beings to use electric energy on a large scale. " In the following time, we did another experiment. We first prepared a compass, a battery and a wire, then straightened the wire, removed the plastic at both ends of the wire to expose the copper core, and then connected the copper core at both ends of the wire to the positive and negative poles of the battery. Then we approached the small compass, and at this moment we observed that when the wire approached the compass, the compass suddenly turned around. After disconnecting the current, the compass is as quiet as a child who has just been taught. The teacher told us so.

Science and technology support civilization and create the future. The future is in our hands. Let's become knowledge explorers, roam on unknown roads, and make the world we live in a better place with unlimited creativity!

Write a composition about the great changes that modern science and technology have brought to our lives. We live in an information world.

There are more and more information in modern society, the speed of transmitting information is getting faster and faster, and the ways for people to obtain information are getting wider and wider. The information tools in my home are: mobile phone, telephone, TV and computer.

Now that mom and dad each have a mobile phone, it's much more convenient to contact friends and family. Modern high technology has brought great changes to our lives.

I remember that once the teacher left us an assignment to look up some stories about celebrities. In the past, I had to spend an hour or two browsing newspapers and books.

Now as long as I turn on the computer, surf the Internet and enter the information you want, the answer you want will appear on the computer screen in a few seconds, which greatly improves the efficiency of my homework. Now, I have a computer at home, so it is convenient to contact my brother in Japan.

Just sit in front of the computer, click the mouse and enter the QQ video chat room, so my brother and I can chat face to face. I remember once, my brother sent me a video of Japanese cherry blossoms in full bloom. Seeing them, I seem to smell their faint fragrance, as if I were in the ocean where they are in full bloom.

Although I haven't been to Japan, I have learned a lot about the local conditions and customs of Japan by talking with my brother and sending pictures. This is the pleasure brought by the Internet. Tick-tock, dad's coke is broken these days. He held his mobile phone all day, read the instructions, pressed the button from time to time and muttered something.

Why? Just because he changed his cell phone. This new mobile phone has so many functions! You can not only make phone calls, but also send short messages, order weather forecast information, set color ring tones, surf the Internet and so on.

Although the shape is small and exquisite, it can hold the world inside, which is really different from the old mobile phone! In the past, my father always hung a big and old-fashioned mobile phone, which looked very rustic and had no function. He can only call and send text messages. What bothers my father most is that it is an English machine, which only displays English, and my father can't understand it. A friend sent a text message, and a big English letter appeared on the screen, which made people dizzy.

At this time, my father shook his head again and again: "Alas, this mobile phone is really backward!" " "When he shook his head and sighed, the development of mobile phones began to advance by leaps and bounds, even with each passing day. That day, he excitedly went to buy a mobile phone.

When I got home, I said cheerfully, "The mobile phone is really good now! You can not only input translation function, but also take photos online. Mobile phones combine the functions of cameras and computers, and the development speed is really fast! Since changing the mobile phone, my father has learned to send and receive short messages, and the function of using the mobile phone has become a piece of cake. The development of mobile makes him keep up with the times.

This is the network that has changed my family's life and made my family happier and warmer. This is the change that high technology has brought to life. The internet is really amazing. The Internet has changed our lives.

6. How to write a good scientific composition With the rapid development of modern science and technology, we have stepped out of the previous era of eating blood 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 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.

7. Write a scientific paper "Hahahaha ……" On the way home from the Science and Technology Department of Heilongjiang Province, the carriage was filled with bursts of laughter.

The Science and Technology Museum is located in Harbin Sun Island Science and Technology Park, covering an area of 50,000 square meters and a building area of 25,000 square meters, including a permanent exhibition hall 1.2 million square meters and a temporary exhibition hall 1.5 million square meters. If nothing else, these four figures alone are enough to illustrate the verve of the Science and Technology Museum!

The exterior design of the Science and Technology Museum is quite unique, with towering columns on both sides, concave in the middle and a huge sphere in the middle. From a distance, smooth lines and perfect combination fully embody the spirit of a modern science and technology; It gives people an endless reverie, a sense of mystery, and a desire to be close.

The whole science and technology museum is full of advanced technology that people can experience personally. It is practical, operational and entertaining ... it is participatory. I have personally operated many projects and facilities. I have melted myself into science and turned myself into a great scientist in one day. I was deeply moved by science.

There are simulated driving, fairways, 4D movies and fire experiments ... all of which are very interesting!

I especially like to play bowling in the mechanical exhibition hall on the first floor. The project consists of many mechanical principles, such as: conveyor belt conveying iron ball, lever lifting track ... this is very manual, and several of us, Qi Xin, pass the ball to the end, that is, the starting point; Then, re-transmit, and then reach the end point, and so on. Let us feel very novel.

Simulated driving is also a cool sport. The car model is completely simulated, the steering wheel and the rudder used for shifting make people feel very satisfied, and the driving effect is very realistic. However, because I am very nervous, I always put out the fire and am disappointed.

What makes me happiest is the 4D movie. 4D movies mainly make people wear glasses that can be seen three-dimensionally, so everything they see seems to be in front of them. At the same time, with all-round three-dimensional, seat swing, blowing and spraying water, the immersive effect arises spontaneously. This film is a thrilling virtual animation. When the spaceship flies in front of your eyes, there will be strong winds. When the hero enters the bottom of the sea, you will also feel the seat suddenly sink, and your body and mind will sink with it. Really * * *; And in front of the mermaid, she looks at you and sprays water on you. It was really fun! Then, when a group of mice come at you, you will feel that there are mice everywhere under your feet, which is very exciting. Actually, it was just a special effect! The 8-minute thrilling 4D short film not only refreshed me, but also made me unforgettable!

At the end of the day, I am really happy and fresh. I not only learned a lot from playing, but also had a good time while learning knowledge. This day is my happiest day!

8. The 800-word composition on the topic of modern science and technology is progressing, the level of knowledge and culture is getting higher and higher, science and technology are also progressing, and tragedies and comedies are quietly staged.

Among many scientific and technological achievements, the discovery of genes is a news that cannot be buried. In the study of gene problems, human beings finally found these three types of genes through scientific argumentation and reasonable inference: aa, aa, Aa, which changed the difference of human ears: AA type has no earlobe; Both Aa and AA have earlobes. This seems to be good news, but in fact, scientists are faced with another difficult problem-how do genes pass through the human body and carry out genetic inheritance?

With this question, scientists once again entered the world of cloning. Cloning is a kind of high technology, which was put forward by British scientists and solved first. After his success, the world's first cloned African Xenopus was born. Later, American scientists and China scientists cloned some small animals, and both achieved good results. Subsequently, American scientists first cloned Dolly. Under this good news, scientists began to attack human beings and wanted to clone them. But a scientist raised a negative question: "If there is a clone, what is it?" I remember watching a movie called "Clone". In the movie, human cloning can do anything. I think, if the clone really has these skills, how can he survive?

Give another example. Now people have invented all kinds of nuclear weapons, the most advanced of which is the atomic bomb, which is a symbol of national authority. At that time, under the leadership of Deng Jiazhuang, China organized a group of researchers to study the atomic bomb. After a long effort, China's first atomic bomb exploded in western China. But at the moment of explosion, who would have thought: how many lives and how much environment would be endangered by such a highly toxic and lethal bomb? In the First World War, the American military dropped an atomic bomb named "Little Boy" in Japan. As a result, millions of people died and the environment was seriously polluted. Isn't this another example of the harm that science does to mankind?

9. Poetry describing the rapid development of modern science and technology and writing articles with ancient poems can change greatly or quickly. Without looking back on the heroic past, all indicators are red. The rural economy has developed steadily and farmers' income has increased steadily. The coal industry is solid and powerful, and its development foundation is relatively solid. The pace of opening up and introduction has been accelerated, and the project construction has achieved remarkable results. Urban and rural construction has developed in an all-round way, infrastructure has been significantly improved, and harmonious construction has been pragmatically promoted. All walks of life in society have made all-round progress. Looking forward with confidence, the expected goals are increasing in an all-round way. The county party committee * * * pays close attention to the implementation and realizes the strategic goal. Revitalize the county economy in an all-round way and strive to catch up with advanced counties and cities. Six new breakthroughs have been achieved: First, the policy of "closing small and building large" has been implemented around safety production, laying a solid foundation for safe development, extending the coal industry chain and making new breakthroughs. The second is to vigorously develop one village and one industry around one village. Strive for a breakthrough in the construction of new countryside. Third, adhere to the principle of protection and development around tourist counties. Do a good job in the construction of supporting factors for strengthening the county and enriching the people. Fourth, focus on basic education and strive to do a good job in campus construction. Strengthen the construction of teachers, optimize the overall layout of schools, and achieve new breakthroughs in urban and rural basic education. Fifth, focus on environmental protection and do a good job in the construction of the safety system. Strengthen governance and protection to show the public's concern for people's livelihood. Breakthrough progress has been made in harmonious construction. Sixth, around creating a good environment, actively optimizing the allocation of resources, strengthening the construction of administrative efficiency, introducing superior capital through multiple channels, and making breakthroughs in major projects. The whole party mobilized the whole people to make unremitting efforts to build a beautiful new Ningwu with prosperity, civilization, harmony, stability and vitality.

10. How to write a scientific composition? You can write those contents. In August, my parents took me to Pudong to visit the Shanghai Science and Technology Museum.

Shanghai Science and Technology Museum is a modern building, which is very spectacular. The building is concave with a big ball of transparent glass curtain wall in the middle.

The whole architectural style is unique, and the asymmetric structure with low west and high east spiral is eye-catching. Entering the Science and Technology Museum, a tall balloon man in a spacesuit waved to meet us, as if welcoming our little guests from afar.

First of all, we came to "scientific and technological exploration", where we mainly showed some scientific and technological methods and principles. There is a big faucet hanging in the air in the center of the exhibition hall, which attracts our attention without connecting any water pipes. I searched around the pool again and again, but I couldn't find a place to connect the water pipes. That's great! At this time, I saw an aunt with long hair, and all her hair stood on end. What happened? I hurried over and saw my aunt touching a big iron ball with one hand. The iron ball was charged, which was originally generated by static electricity.

In science class, the teacher once told us the principle of static electricity. I really enjoyed seeing the real experiment this time! Walking along the exhibition hall, we came to "Crustal Exploration", where many mineral resources were exhibited. It contains samples of rubies, crystals, diamonds and other minerals. There is a real ivory about 3 meters long in the center of the hall, and the ivory shines in the light. This is a dazzling exhibition hall.

There is also a simulation field to simulate volcanic eruption and create earthquakes. Being in it is like being there. Timid people all run forward with their heads in their arms, screaming with fear. It really is * * *! In addition to the exhibition hall above, we also visited the Children's Science and Technology Museum, Audio-visual Park and Subtropical Botanical Garden. In a blink of an eye, the museum will close. Here, we only feel that time passes quickly and people are reluctant to go. If there is an opportunity, everyone will come to Shanghai Science and Technology Museum. There are many interesting, thrilling and wonderful things waiting for you to discover and experience! Why do leaves turn red? Everyone knows that maple leaves turn red in autumn, like a burning flame, very beautiful.

But you all know why maple leaves turn red in autumn. I was puzzled, so I looked up the book and searched the Internet. I see. It turns out that some chemical changes will take place in deciduous trees in autumn and winter, so that useful substances or some tissues contained in the original leaves can be recycled and stored in stems or roots after decomposition.

Among them, there is a special pigment called anthocyanin, which is a "chameleon" and is red in acidic solution. With the change of seasons, the temperature and sunshine increase or decrease correspondingly, and the main pigment components in leaves also change. Autumn comes, the temperature drops, the light weakens, and the anthocyanin composition changes, while the leaf cell sap of red-leaf trees such as maple leaves is acidic, so the whole leaf is red.

I did another experiment according to the book: I picked some red leaves from the tree. When I got home, I chopped the red leaves. Then I boiled them in water, and the water turned red. Then I added some dilute hydrochloric acid to the water, and the water became redder. Finally, I made a small cup of soapy water and poured it into the water. The red water miraculously turned blue. This experiment proves that red leaves are sour. 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.
