In daily study, work or life, everyone has the experience of writing a composition, so you are familiar with it. According to different genres, the composition can be divided into narrative, expository, practical and argumentative. In order to make your writing easier and more convenient, here are 4 words (selected 14 articles) that I have compiled for you, hoping to help you. Playing can also play tricks. Composition 1

It is the nature of every child to love to play. After I was a child, I was also lively and playful. In the hands-on practice, I have continuously increased my knowledge and improved my ability.

one day, I was playing in the house and rummaged through the cabinets and found some magnets. I was young at that time, and I didn't understand the principle of magnets. I just played around. I suck this and that with a magnet and have fun. I didn't know that there was a big problem waiting for me to solve ...

I found a strange phenomenon when I was playing: sometimes a magnet can't attract another magnet at all, and the two magnets bounce off before touching each other. I picked up a magnet and approached one. As a result, the magnet actually moved by itself. Anyway, he just couldn't close it. The two magnets were getting farther and farther away, which made me feel interesting and confused. I felt that there was knowledge in the small magnet that I didn't understand.

I was puzzled. I took some magnets and ran to ask my father what was going on. Is it broken? Dad smiled and said, no, there are positive and negative poles on the magnet. Once the magnets are different, they can't be attracted together.

It dawned on me when I heard it. I looked at the magnet in my hand. It is no longer a toy magnet, but a useful toy with a lot of knowledge.

On that day, I had a new understanding of magnets and expanded my knowledge a little. Although many people knew it, it was new knowledge for me. That time, I really played a famous game. Levin Hooke invented the microscope in play, and I learned the positive and negative levels of magnets in play. You can also play tricks by playing. 2

Everyone likes to play, but who has played tricks? I played a little trick yesterday afternoon.

Yesterday, my good friend Shao Jiantong and I were playing in my mother's office. Suddenly it occurred to me that I wanted to use chalk foam to adjust the color water. So I told Shao Jiantong what I thought, and he agreed.

We started looking for materials. I said, "Just some chalk heads." Shao Jiantong began to be busy. He brought some white ones, some blue ones and some pink ones. I found a plastic bottle, put the chalk in it, then I poured some water, covered the bottle cap and shook it hard. After a minute or two, I opened the bottle cap to see my "achievement". I poured this half bottle of water into clean water, and I saw an amazing water-it was a purple and blue color. I was just about to look at the chalk foam when an idea came to my mind-would those chalk foams disappear without a trace?

I found that I was right. The chalk foam really disappeared. I also found that the chalk heads are all honeycomb-shaped, which shows that chalk is made of a kind of powder with extremely small particles, which can be melted. This will ensure that chalk will no longer pollute the air.

You see, you can't play foolishly. You should learn to discover and create from playing, so that you can invent magnifying glasses and microscopes like Levin Hook in the Netherlands and really play tricks! Play can also play tricks. 3

Playing is often regarded as a waste of time, but I think playing can also play tricks.

I like to play top. The reason why I like gyro is that playing gyro can bring us fun and train our patience.

My gyro is not the kind I bought from the street, but the old bobbin my grandfather brought back from the factory. It is very small, only about an inch high, but it can turn quickly and for a long time. One day, when I finished my homework, my grandfather taught me to play with the gyro. We used a big plate as a battle plate. When my grandfather twisted three fingers, the gyro quickly turned on the plate. I also tried to twist it like my grandfather, but the top never turned. Grandpa asked me to use a little force, so I tried again. Alas, it still didn't turn. I don't want to learn. Grandpa said, "You can't do anything by halves." After listening to grandpa's words, I sat down and studied hard. I twisted it hard with three fingers, and the gyro turned quickly in the plate. I was so happy that I practiced alone. I practice, observe and think. I have come to the experience that the three fingers of the gyro should be forced at the same time to keep balance, so that the gyro can turn longer. Now I can play the top fast and long.

I learned the truth that you can't give up halfway when you do anything by playing the top. You should think more about the problem, so that you can play well. You can also play tricks by playing. 4

Many interesting things will happen in life, and some people who love life will find something worth studying and exploring, then experiment from the essence of this thing and finally invent great things. For example, Boyle in England, because I love flowers, I am good at observation and diligent in thinking, from which I invented the stamen test paper commonly used in experiments. But it's different. Only famous scientists are qualified to invent. As long as you pay attention to the details of life everywhere, you can play tricks even if you play.

Leeuwenhoek, the pioneer of microbiology with microscope. He likes playing with lenses very much. Once Levin Hook was playing with a magnifying glass again. He suddenly wondered what would happen if two magnifying glasses were put together. So he slowly put the two lenses together according to his own ideas. Look at a mosquito's leg. Ah, great. Mosquito's legs are as big as rabbit's. The grass on the ground is like green leaves.

The more he played, the more energetic he became. He fixed one magnifying glass so that the other magnifying glass could be adjusted at will, thus making a miniature microscope. He also observed the water with a microscope, and found that there were many small creatures jostling around in the water. Observing his teeth with a microscope, he discovered a new world that no one had ever discovered ...

Many people think it is a waste of time to play this game, but if he is good at observing, asking questions and constantly exploring, he can play strange phenomena even if he plays. You can do great things.

Scientific discoveries belong to everyone. As long as you think hard, explore hard and keep asking questions, your name will appear in the scientific community one day. Play can also play tricks. 5

Playing is often regarded as a waste of time. However, in the history of science, many great inventions were produced by those inventors in the process of playing.

for example, Thomas Watson, Bell's assistant, got rid of the trapped reed one day, but Bell heard the fluctuation from his neighbor on the wire. He wrote down the facts, after some experiments and humbly asked for help, got the help of some famous experts, found something famous while playing, and invented the first telephone with his own knowledge. Bell's invention turned a new page in the history of telephone development.

There is also Levin Tiger. He watches the door alone. He always feels very relaxed, so he plays with the lenses. He grinds the sides of the lenses thin. He thinks: What if two pieces are put together? As soon as he tried, it was amazing that mosquitoes' legs were like rabbits'. He observed the water with a magnifying glass and found a "lilliputian country", so the magnifying glass was invented.

Darwin, who loved insects since he was a child, often caught small animals to play with and bugs in the fields. He often crawled on the road and observed the habits of small animals. He also had many animal specimens. Later, he created the theory of evolution.

in addition to these deeds, there are many great inventions that were made famous by inventors.

Play can also produce famous things, but if there are any accidental opportunities in invention and creation, these accidental opportunities will only be given to those who are good at playing, because for them, playing is a kind of enjoyment, which is more important than what is discovered by rigid learning. Therefore, only by combining work and rest, playing, observing and paying attention when playing can we produce famous things. You can also play tricks by playing. 6

My father is a computer geek, and he is also a "garbage collector." My bedroom became his "garbage collection station" and my desk became his "operating table." Dad is always at his desk, fiddling with the rubbish he picked up from other people's homes, and sitting for hours. Although my mother and I complain every day, he still goes his own way.

The induction cooker at home went on strike, and my mother kept urging me to buy a new one, but my father said, "Leave it to me." With that, he put the induction cooker on the "operating table", cut the cavity and cut the belly of the induction cooker with a screwdriver. After finding the symptoms, he plunged into the "garbage dump". After a rummaging, he found the right chip and put it in the induction cooker. The induction cooker worked miraculously again. I can't help admiring: "Dad, you are awesome!"

My father is not only good at "waste utilization", but also active in innovation. There is only one smart lock in the car at home. If it costs a lot of money to match another smart lock, my father is reluctant to spend money. He thought for himself, bought the shell of the smart lock online, took down the chip of the mechanical lock after heating it with a hair dryer, and then carefully welded the chip in the newly bought lock sleeve with an electric welding machine, and everything was ready. Dad took his "partner"-laptop again and got into the car to work. One hour, two hours, three hours ... Still no sign of dad. Finally, a tired-looking father came back. He said with satisfaction: "My experiment was successful. At last, our family has two remote-controlled smart locks, and all the hidden functions in our car have been opened by me." Looking at my father's face of satisfaction, my mother and I couldn't help laughing.

I admire my father. He made progress in playing, changed our lives with his intelligence and made great achievements. It is said that playing is a child's nature, but playing in the eyes of adults is often considered a luxury. They always think that playing will waste time and delay learning, but they ignore that many great discoveries in human history are made in playing.

one day between classes, I took out a piece of paper to play with when I had nothing to do. I spread the paper on the table and folded it in half again, and then folded it into a triangle along the diagonal. I was thinking about what to fold next, when I suddenly saw pen scraps and draft paper on the table, so I had a brainwave, folded the two bottom corners of the triangle upwards respectively, and then opened it, and a small paper box was displayed in front of my eyes. Ha, this is my simple trash can. I cleaned up the pen scraps and draft paper on the desk in the "trash can", and suddenly the desktop was clean.

Improvisation made me suddenly interested. I took out another piece of paper and folded the frog my father taught me to fold before. Looking at this frog, I felt something was missing. Take a closer look. Haha, this is an eyeless frog. I quickly took out my crayons, drew eyes on it, and helped it put on "clothes". This frog is lifelike under my finishing touch. Later, I found a major problem. The frog couldn't jump. I tried several times, but I couldn't jump. Isn't a frog that can't jump disabled? Throw it away. I threw it into my trash can casually, but I just threw it in and couldn't bear to part with it. It's the result I made. What a pity to throw it away like this. Isn't the teacher always encouraging us to be innovative and creative? I might as well transform it and make the best use of it. When I said I would do it, I transformed this "semi-disabled frog" to make its legs more stable. After folding, I put the pen on it, and sure enough, it was firmly held. Yeah, "Frog Penholder" succeeded.

I couldn't help laughing when I looked at the trash can and pen rack on the desk. Hehe ..... Who says it's useless to play? You can play tricks by playing! You can also play tricks by playing. 8

Many people think that playing this thing is intolerable, but there are many things in the world that are played! There are many, many, such as microscopes, airplanes, steam engines and so on.

Throughout thousands of years, many people are famous for playing, and almost all of them have created miracles from common objects.

Microscope, a scientific instrument that everyone knows, is also found in many people's homes. Do you know how it came from? It was also played out. It was invented by Levin Hooke in 1632. At that time, his work was also very free, so he often grinds his lenses when he has nothing to do at work. He often grinds while watching the gate and makes a magnifying glass. It suddenly occurred to him what would happen if they were put together, so he overlapped the two lenses and saw the skin on his hand, and made this amazing discovery. Then he made a simple microscope with these two lenses and discovered a brand-new microbial world.

Telephone, as many people know, is also played. One day, Thomas, Dale's assistant, fiddled with the trapped reed, but Bell heard the plucking string sound from the neighbor's house. In order to further test, on March 1, 1876, Bell shouted through the transmitter: Mr. Watson, please come here! I want to talk to you about something! Watson's assistant, who heard the call in the laboratory, rushed out of the laboratory like crazy and ran to the dormitory where Bell called out to him. Along the way, he kept shouting: I heard Belle calling me just now! I just heard Bell calling me!

in the history of science, there are many such examples. It shows that science is not mysterious and truth is not far away. While playing, we need to be curious and be good at thinking. Then, let's be good at playing together and make a name for ourselves! You can also play tricks by playing. 9

Parents often say that our main task now is to study, and only by studying can we have a bright future. But can learning really make us successful? In my opinion, proper play can also make us make many new discoveries and benefit us for life.

I remember when I was in the third grade, lesson 15 of Chinese talked about Anthony, a great Dutch watchman. Levinhook. He is a doorkeeper and bell ringer. Once he was idle, he came up with a new way of playing, putting two magnifying glasses together. After many experiments, he invented the microscope and observed microorganisms for the first time through the microscope.

There were similar examples in ancient China. For example, Lu Ban saw a toothed leaf and invented a saw. Lei Zu saw silkworms cocoon and created silk ...

This reminds me of my family's shyness? . It is placed on my balcony, and there are about a dozen plants planted in a basin. It's fine when I just bought it back. When I touch the leaves, they will close, and then they will open again. But after a month or two, the leaves will not move at all. Two or three days later, the leaves turned yellow, and all of them hung down their heads. I thought, forget it when I die, and plant some more later. Anyway, there are many seeds at home, but I can't raise them for nothing. I have to "open the knife" with them, at least worthy of my "watering money" for so many days. So, I took a basin, dug a plant from the big basin and exposed it in the sun; Another plant was planted in another basin and placed in the shade. It was not watered for several days. can
