Who invented the composition
It has been around since ancient times. I don’t know who the source is. Even if you know you can’t find his graveyard.
Composition is a narrative method that expresses the meaning of a theme through words through human thought consideration and language organization. Compositions are divided into primary school compositions, middle school compositions, and college compositions (essays). Composition genres include: narrative, expository, practical, and argumentative.
Narratives can generally be divided into several types, such as recording people, narrating, describing scenes, and chanting objects. Remembering people should express the characters' thoughts, feelings and personalities; narrating should describe the meaning contained in the event. These meanings can be political and ideological, or they can express some kind of philosophy or some kind of taste.
To describe a scene, you should express some personal feelings or deep insights through the description of the scene; to chant an object, or to reveal a certain pleasure of life in the world, or to express your ambition with an object, to express your feelings towards a certain person in society. emotion of a certain phenomenon.
Therefore, when we write narratives, we always have a certain purpose and express certain thoughts and feelings. In fact, it is what we usually call the "theme of the article". The theme is the soul of the article. It is like A red thread runs through the article.
A narrative without a clear theme can only be a running account. Therefore, to write a good narrative, it is necessary to clarify "why it is narrated", that is, the theme must be clear.

Hands-on practice is the most basic skill for a person. If people have doubts or confusion in their lives, they must practice it. Practice will make them good. Let you get the real answer.
Practical operation is the main factor that makes many of our celebrities famous. There is an example of such a celebrity: Wang Xizhi loved calligraphy since he was a child. He practiced hard for decades and finally made his calligraphy art reach the level of The extraordinary peak is known as the "Sage of Calligraphy". When Wang Xizhi was 13 years old, he accidentally discovered a calligraphy book called "Shuo Bi" in his father's possession, so he stole it and read it with gusto. His father was worried that he was too young to keep the family history secret, so he promised to teach him calligraphy when he grew up. Unexpectedly, Wang Xizhi knelt down and asked his father to allow him to read now. His father was very moved and finally agreed to his request.
Wang Xizhi practiced calligraphy very hard, even eating and walking. He really practiced calligraphy all the time. Without pen and paper, he just scratched on his body. Over time, his clothes were scratched. Sometimes I practice calligraphy to the point of forgetfulness. Once, when he was practicing calligraphy, he forgot to eat. When his family brought the meal to the study, he dipped it in ink and ate it without thinking, and found it very delicious. When the family found out, their mouths were full of black ink.
Wang Xizhi often came to the pond to write and wash his inkstones. After a long time, the water in the pond ran out of ink, so it was called "Mochi". Nowadays, there are scenic spots called "Mochi" in Shaoxing Lanting, Zhejiang Yongjia Xigushi Mountain, Lushan Guizong Temple and other places.
Wang Xizhi’s calligraphy art and hard work are highly praised by the world. Legend has it that Wang Xi

A 380-word essay on my invention story
A few days ago we studied the unit of inspiration from nature. Now, let me tell you about the inspiration that nature gave me. Something that makes me want to invent.
That was when I went to Longmen Grottoes. I saw a water spider floating on the water. At this time, a bright spot came to my mind: If we can also think of water spiders that can float on the water, How wonderful it would be to walk on it! After I got home, I carefully studied the highlight, and then wanted to invent a "water walking shoe". The bottom of this kind of shoe is an air cushion, which can support the human body, so that people can walk on the water as they like!
If I grow up and can invent this kind of shoes, how much convenience it will bring to people!

On March 3, 1847, Alexander Bell was born in Edinburgh, England. His father and grandfather were both well-known linguists.
Influenced by his family, Bell was very interested in languages ??when he was a child. He likes to raise small animals such as sparrows and mice. He found the sounds of animals to be beautiful. When he was in elementary school, in addition to textbooks, his books often contained insects, small mice, etc. One time, the teacher was telling stories from the Bible. Suddenly, a mouse came out of his schoolbag. The students hid and screamed, causing chaos in the classroom. The teacher was furious and felt that such students could not be taught.
Soon, Bell's father sent Bell to his grandfather in London. Although this kind old man loved his grandson very much, he was very strict in his discipline. Grandfather was well aware of the learning psychology of teenagers. He did not use the cramming method to force Bell to learn knowledge from books, but started by cultivating Bell's interest in learning. Gradually, Bell developed a strong desire for knowledge, and his academic performance improved, becoming a top student. Bell later recalled: "My grandfather made me realize that it was a shame that I didn't know the common lessons that every student should know. He aroused in me the desire to study hard."
一Years later, Bell returned to his hometown of Edinburgh. Near his home, there was a mill. Bell felt that this old-fashioned water mill was too laborious and needed to be improved. So he consulted various books and materials and designed a sketch of an improved water mill. Although this picture is not drawn in a standardized way, the conception is very clever. After the craftsmen's processing, the water mill has indeed become very flexible and much less labor-intensive than before. From then on, he became a well-known "little inventor".
Bell saw the significance of invention and creation from here. Every invention will benefit a large number of people and is a cornerstone for mankind to move forward.
In 1869, the 22-year-old Bell was employed at the University of Boston in the United States and became a professor of phonetics at the university. In addition to teaching, Bell also researched teaching equipment.
Once, while doing a "visual language" experiment for deaf-mute people, Bell discovered an interesting phenomenon: when the current flows and cuts off, the spiral coil will make noise, just like a telegraph machine It's the same "tick" sound it makes when sending Morse code.
"Electricity can make sound!" Bell, who was quick-thinking, immediately thought, "If the intensity of the current can be changed to simulate the changes in sound waves when a person speaks, then the current will not only be transported like a telegraph Signals can also transmit sounds produced by humans, which means humans can transmit sounds using electricity. "
The more Bell thought about it, the more excited he became. He thought: "This must be a very valuable idea. "So, he told his friends in the electrical field about his idea, hoping to get useful suggestions from them. However, when these electrical experts heard this strange idea, some disapproved, some laughed, and one was even rude. Said: "As long as you read a few more books like "Common Sense of Electricity", you won't have this illusion. ”
Bell was disappointed, but he was not depressed. He decided to ask Mr. Henry, the master of electromagnetics, for advice.
After listening to Bell’s introduction, Henry Smile and say, “That’s a great idea! I think you will succeed! "
"Dear sir, I am studying phonetics and do not understand electromagnetism.
Bell said timidly, "I'm afraid it will be difficult to become a reality." "Then you learn it." "Henry said decisively.
With Henry's affirmation and encouragement, Bell felt that his thinking became clearer and his determination was greater. He secretly made up his mind: "I must invent the telephone. "
After that, Bell dove into the library, starting from reading "Common Sense of Electricity" until he mastered the latest electromagnetic research trends.
With a solid knowledge of electromagnetic theory , Bell began to prepare for the experiment. He invited 18-year-old electrical technician Watson to be his experimental assistant.
Then, Bell and Watson began to experiment in the laboratory all day long, repeatedly designing plans. , processing and production, but failed every time. "I think you will succeed", Henry's words always echoed in Bell's ears, inspiring Bell to devote himself to the research and development work with full enthusiasm.
Time passed like water, and two years passed.
In May 1875, Bell and Watson developed two crude prototypes. The two prototypes were covered with a film at the bottom of a cylinder. A carbon rod is vertically connected to the center of the film and inserted into the sulfuric acid solution. In this way, when a person speaks to it, the film is vibrated, and the resistance of the place where the carbon rod contacts the sulfuric acid changes, and the current also changes; when receiving, Due to the change in current, sound waves were generated, thus achieving sound transmission.
However, after verification, the two prototypes still failed to communicate.
After repeated research and inspection, Bell confirmed that there was nothing wrong with the design and production of the prototype. “But why did it fail? "Bell was thinking hard.
One night, Bell stood in front of the window, frowning in thought. Suddenly, the melodious guitar sound came from the distance. The sound was crisp, deep, and wonderful. !
"By the way, Watson, we should make a speaker to increase the sensitivity of the sound. "Bell was inspired by the sound of the guitar.
So the two immediately designed a production plan. Without materials, they dismantled the bed board. After several hours of hard work, the speaker was completed.
p>On June 2, 1875, they tested the prototype with a speaker. Bell was in the laboratory, and Watson was at the other end of the room a few rooms away while Bell was adjusting the machine. Called into the microphone.
Suddenly, Bell accidentally splashed sulfuric acid on his leg while operating, and he couldn't help shouting: "Mr. Watson, come on, I need you!" "
"I heard it, I heard it. "Watson happily rushed over from the other end. He ignored Bell's injury and hugged Bell tightly. Bell forgot about the pain at this time and was so excited that tears filled his eyes.
That night, Bell couldn't sleep. He got up in the middle of the night and wrote a letter to his mother: "Today is an important day for me. Our ideal has finally come true! In the future, telephones will be as much a part of homes as running water and gas. People can talk at home without going out. ”
However, people reacted indifferently to the birth of this new thing, thinking that it could only be used for games and had no practical value.
On the one hand, Bell improved the prototype; On the one hand, he used every opportunity to promote the value of the telephone.
Two years later, in 1878, Bell conducted the first long-distance telephone experiment between Boston and New York (the two places were 300 kilometers apart), and the results were also successful. After that, telephones quickly became popular in major cities in North America.

The story of Bell’s invention of the telephone
Today, The telephone has entered thousands of households. Do you know who invented the telephone?
Bell was born in England in 1847. When he was young, he worked with his father as a teacher for the deaf. I once wanted to build a machine that would allow deaf-mute people to see sounds with their eyes.
In 1873, Bell, who became a professor at Boston University in the United States, began to study the multiplex telegraph, a device for transmitting many telegrams on the same line, and came up with the idea of ??using electric current to transmit human voices to distant places. , so that people who are thousands of miles apart can talk face to face. So Bell began researching telephones.
It was June 2, 1875. Bell and his assistant Watson were testing multiplex telegraph machines in two rooms respectively. An accident inspired Bell. There was a spring on the telegraph machine in Watson's room that was stuck to the magnet. When Watson pulled the spring open, it vibrated. At the same time, Bell was surprised to find that the spring on the telegraph machine in his room vibrated and made a sound. It was the current that transmitted the vibration from one room to another. Bell's mind suddenly opened up, and he thought: If a person speaks to an iron piece, the sound will cause the iron piece to vibrate; if an electromagnet is placed behind the iron piece, the vibration of the iron piece will inevitably be in the electromagnet coil. Produces sometimes large and sometimes small currents. If this fluctuating current is transmitted to a distant place along the wire, wouldn't the same vibration and sound occur on similar devices in the distance? In this way, the sound spreads along the wire to distant places. Isn’t this the phone call you’ve been dreaming of!
Bell and Watson made a telephone according to the new idea. During an experiment, a drop of sulfuric acid splashed on Bell's leg, causing him to shout in pain: "Mr. Watson, I need you, please come to me!" This sentence was transmitted to Watson's ears from the telephone through the wire. Here, the call was successful! On March 7, 1876, Bell became the patentee of the telephone invention.
Bell obtained 18 patents in his life and cooperated with others to obtain 12 patents. He envisioned burying telephone wires underground or suspending them in the air, and using them to connect homes, villages, factories... In this way, direct phone calls could be made anywhere. Today, Bell's vision has long become a reality.
