The family history of pens is probably as long as ours. Tracing back to the source, as early as ancient times, when human beings lived a primitive life, pens appeared, only counting or marking with branches and sharp stones. In slave society, in order to record and preserve some important events, people used knives to carve these objects on animal bones and tortoise shells in the form of words for recording, which is called "Oracle Bone Inscriptions". Probably because people often deal with nature at that time and found that animal hair can absorb water, so they came up with a way to write on a bamboo tube with animal hair, so there was a writing brush. According to the different writing materials, it can be divided into wool, wolf hair and so on. The appearance of the brush greatly saves the recording time and is more portable and practical. Many literati used it to sprinkle various brushes on painters, leaving behind masterpieces and calligraphy treasures.
With the changes of the times and the development of culture and science, pencils developed from graphite pens are developing in an economical, concise and practical direction. In addition to hardness and softness, there are rubber-tipped pencils and movable fine-core pencils, which are widely used by primary school students. After the Qing Dynasty, although the writing brush still played a major role in writing tools, at the same time, a new kind of pen appeared, which is a new member of the writing brush family. They are more than ten centimeters tall, wearing metal or plastic coats, shiny metal heads, rubber bellies and the enviable word "ink". Pen is a proud word in the pen family. Practical, beautiful, smooth, delicate and even lines are beyond the reach of other pen types.
Today, the pen family has developed vigorously, and many new faces have appeared, such as chalk, ballpoint pen, crayon, artistic pen, colored fountain pen and gradually popularized electronic pen. All kinds of exquisite, dexterous, beautiful and practical pens have a wide range of vision and are increasingly updated, which are widely used by people.
Pens are used more and more widely. Nowadays, pens are not only used for writing letters and taking notes. You see, girls use eyebrow pencil to draw eyebrows, and engineers use electronic pen to draw with computers.
Isn't it often said that "pen and ink are earth-shattering, and articles are earth-shattering"? I believe that with the rapid development of science, the pen family will continue to transform, update and develop, and its functions will become more and more complete, which will play a great role in human civilization.
In today's highly developed science, although we practice writing, writing, drawing and calculating with pens every day, do you know the pen family? If you don't know, let me introduce you!
2. The pen with the theme of "pen" is a writing tool for everyone to cultivate in the cultural park. We practice writing, writing, drawing and calculating with pens every day.
But, do you know anything about the pen clan? Let me tell you something. Pens are generally divided into hard pens and soft pens.
Speaking of the family history of pens, I'm afraid it's as long as us humans. Tracing back to the source, as early as ancient times, there was a "pen" in human life, which only used branches and sharp stones to count or mark.
In slave society, people found that animal hair can absorb water, so they came up with a way to fix an animal hair on a bamboo tube to write. This is a writing brush. According to the different writing materials, it can be divided into wool, wolf hair and so on. The appearance of writing brush greatly saves recording time and is more portable and practical.
How many literati used it to splash painters' various brushes, leaving masterpieces and calligraphy treasures. After the Qing Dynasty, a new kind of pen appeared, which is a new member of the pen family. They are more than ten centimeters tall, wearing metal or plastic coats, shiny metal heads, rubber bellies and full of "ink".
Pens are the darling of the pen family. Practical, beautiful, smooth, delicate and even lines are beyond the reach of other pens. With the changes of the times and the development of culture and science, pencils developed from graphite pens are developing in an economical, concise and practical direction. In addition to hardness and softness, there are rubber-tipped pencils and movable fine-core pencils, which are widely used by primary school students.
Today, the pen family suddenly prospered, and many new faces appeared, such as chalk, ballpoint pen, crayon, artistic pen, colored fountain pen and so on. All kinds of exquisite, dexterous, beautiful and practical pens are increasingly updated and widely used by people. Pens are used more and more widely. Nowadays, pens are not only used for writing letters and taking notes. You see, girls use eyebrow pencil to draw eyebrows, and engineers use electronic pen to draw with computers.
Isn't it often said that "pen and ink are earth-shattering, and articles are earth-shattering"? I believe that with the rapid development of science, the pen family will continue to transform, update and develop, and its functions will become more and more complete, which will play a great role in human civilization. = = = = = = = = = = = = = = = Pen Since Cai Lun invented paper in the Eastern Han Dynasty, various writing tools-pens came into being.
The pen family flourished: brushes, pencils, ballpoint pens, pens ... These pens have produced various descendants, but pens are the most commonly used now. Pens can be regarded as a big category of pens.
According to the ink storage method, it can be divided into two types: dip pen and unsolicited pen. Dip pen, as the name implies, is to dip the pen tip in ink to write. Sometimes we just call it a dip pen.
Because of its unattractive appearance, simple structure, troublesome writing and inconvenient carrying, it has long since withdrawn from the historical stage. Now we use fountain pens that can store ink.
Because of its fluency, portability and low cost, it has become the favorite of many writers. Pens come in different shapes and colors, but they generally consist of a shell, a barrel, a nib and a cap. There is a small "ink bottle" bag in the pen tube. When absorbing ink, as long as you squeeze the capsule hard to expel air, and then insert it into the ink, the ink will be sucked in.
When writing, the ink in the capsule flows from the tongue to the nib. The nib is made of wear-resistant metal, which is thin and durable, unlike the feather tube, which will thicken if it is written too much. The most expensive part of a pen is the nib.
The nib is divided into three categories: gold nib, iridium nib and steel nib, of which gold nib is the best, iridium nib is the second, and steel nib is the second. The gold nib is made of gold mixed with silver and copper. The more copper, the harder the gold pen.
The iridium electrode tip and the steel electrode tip are made of stainless steel. Gold tip and iridium tip have small round particles, but steel tip does not.
This is why steel tips are not as durable as gold tips and iridium tips. That small round particle is iridium alloy, which is called "strong cathode agent" of metal. Very rare and very wear-resistant, it can withstand the scouring and corrosion of ink every day without being washed away.
This is also the secret of good durability of pens. = = = = = = = = = I am an ordinary mechanical pencil.
The little master takes me to school every day, and uses me to calculate, draw, write and so on. However, I didn't always "follow" my master. My father and grandfather played a great role.
Let's talk about my grandfather first! I'm afraid there is no one who doesn't know my grandfather. At that time, my grandfather could buy it everywhere. Even now, someone is using him.
However, compared with me, grandpa is still very backward. Well, I won't do it either. My grandfather is a famous wooden pencil. You will definitely say, "What's the big deal about wooden pencils!" Don't underestimate my grandfather, he is an indispensable writing tool for people in previous years! Grandpa is made of wood, with a refill in the middle and painted green or various colors outside.
Grandpa's refill is made of lead. Cut it out and sharpen it when you buy it. Cut it again when it's used up. You can buy it after cutting it. It's inconvenient, but it's the only way. Year after year, day after day, grandpa is old and it's time to retire. At this time, my father took over my grandfather's position.
My father is much more advanced than my grandfather, but there is still a certain gap with me. During the years of working for the young master, the young master liked him very much. Dad is more beautiful and convenient than grandpa. Although expensive, he is still loved by people.
Dad's "working principle is simple: put a lead as thick as a ballpoint pen core and cut the lead on the pencil sharpener at the top of the pen cap." This is much more convenient than grandpa's, as long as you change the lead at any time, it will be OK, and it will be much more affordable than grandpa's buying it after using it.
But gradually, dad's problems also came out. The speed is slow, the pen is cut too much and black, and the young master loses confidence in his father because he can't wash it clean. Slowly, I appeared in the little master's pencil box, and my father retired like my grandfather.
I have a nice name: mechanical pencil. As the name implies, I am of course automatic, but the principle of "work" is not much different from my father's.
Put the lead in, press the top cap and the lead will come out. However, even if it is called "mechanical pencil", it is certainly different. The mystery lies in this clue ... what is this clue?
3. Have you ever seen a 600-word composition with the theme of "pen"? The pen in the painter's hand moves gracefully on the paper, drawing the most beautiful scenery in the world? Have you ever thought that what can complete this fairyland-like picture scroll is the one full of bitterness? Every successful painting comes from a magic pen. Sometimes, I really want to be a pen and draw my wonderful life on the vast canvas of life. ...
Being a pen taught me to control myself. Perhaps in every boy's heart, there is always a free and vast sky, where is the boy's dream. I'm no exception, all of which come from that young and frivolous heart. Every time I want to get close, I am pulled back by various cram schools, interest classes and homework exercises. Every time I want to get close to it, I am pulled back by the words "study hard" from my parents and teachers. Until I saw the pen in grandpa's hand, it was a pencil. At first, I didn't understand why you were willing to be bound by others and not to find your own free sky. Why are you doing this? When I saw those amazing paintings and those idle people like you in the trash can, I finally understood that you need a hand to hold them in order to make a difference!
Absolute freedom can only be achieved by burying one's head in oneself, and only by learning to accept beneficial constraints can one succeed in painting and realize one's "pen life value".
Being willing to be a pen taught me to bear the pain. Every time I fail in the exam, I will be depressed and miserable; Every time I witness the success of others, I will be jealous ... But every time I think of you, the pencil that was firmly held in my hand by others and sharpened with a sharp knife, I will take a deep breath, forget my own pain and abandon my distractions. It's you. You're always so tenacious. In order to show my best side, I don't hesitate to let people cut the meat again and again. In the pain of heartbreak, you have no regrets, as if the spring breeze brushed your cheeks, and I also showed a flowery smile! Suddenly, I remembered that sentence, "Heaven is a great responsibility, and people must first suffer from their minds, their bones and muscles, their bodies and their bodies ...". I finally understand that you are exercising yourself in repeated pains, showing the best side to the world and drawing the most beautiful patterns for the world.
How can you see the rainbow without experiencing wind and rain, and how can you succeed without experiencing suffering? Only by learning to bear the pain can you become more frustrated and brave and usher in success.
Being willing to be a pen taught me to believe in myself. I don't have a particularly enviable figure or an impressive appearance. Once, I felt inferior because of this. I also complained about the injustice of heaven. Until I saw you-pencil, under the ordinary appearance, there is a precious and beautiful inner world. I began to forget my inferiority complex and look for my strengths. I found it. I found myself in the field of mathematics, because I have IQ; In the field of speech, I find myself radiant, because I have eloquence ... I begin to understand that there may be emptiness under the beautiful appearance, but under the ordinary appearance, it is precisely the enrichment with rich connotations!
I learned to restrain myself from being frivolous and impetuous; I learned to bear the pain, and I no longer give up easily; I learned to believe in myself and stop giving up on myself.
On the way to success, you need to accept constraints, so that you can keep your ship in order and not lose your way.
You need to bear the pain on the road to success, so that you will be firm and will not give up easily.
On the road to success, you need to stick to your self-confidence, give you happiness and courage, and don't lose motivation.
On the way forward, I want to be a pen … but I am not a pen. I want to find my own success with the spirit of pen!
4. Seek the composition with the theme of "pen" to travel all over the world.
If you travel around the world by boat alone, if you can only take one person to entertain yourself, which one would you choose?
It seems difficult to make a decision.
If you ask me, I will not hesitate to answer: "I will choose a pen."
A pen? I heard someone sigh: I can travel around the world alone and bring a lot of interesting things. Why did you bring a pen? My answer is: Yes, I would like to travel around the world with a pen. You don't like pens, do you? You don't want to meet your friends because you have already met them, don't you? A pen you like is your friend, and it will always accompany you, so I am willing to travel around the world with a pen. If I travel around the world, I will find many interesting and strange things. When these things happen, we should feel them with our hearts. At this time, we should write these things down and tell your heart with a pen. If you are blowing the sea breeze, if you are in a tropical fish forest, if you are on a majestic mountain peak, you can tell the blue of the sea, the air of animals and the magnificent history of mountains with a pen. You must have kept a diary after this trip. When you get back, open the page and savor it slowly. You will be surprised. You will recall the experience of the trip in your mind, and you will feel how meaningful and valuable this trip is.
The pen is your relative, and you can talk to him about psychology anytime and anywhere.

(Opening with the proposal, the general manager takes the full text)
Next, let's meet the new members of the pen family. (Conversion, resulting in the following)
Electronic computing pen. Engineers, designers, accountants and scientists do a lot of calculations every day. In developed countries, electronic computers are their necessary tools. In order to make their work more convenient and efficient, people made an electronic computing pen.
Do you think this pen must be big and stupid? No, its length and thickness are similar to those of ordinary ballpoint pens, except that the lower part of the pen holder is equipped with a conical nib with a ballpoint pen core, which can write 6000 words at a time and can be replaced at any time after use. The upper part of the pen holder is equipped with a micro electronic calculator with battery, which can perform elementary arithmetic, percentage operation, power operation and professional operation of commercial finance and trade within 8 digits. Very convenient! (First, a typical pen with a special device is introduced in detail. )
Automatic disappearing pen. The words written with a pen can't be erased. Is there a pen that can erase handwriting like a pencil? This kind of pen really appeared. The ink it uses is made according to a special formula. After writing, as long as you wipe it with clean water or a sponge containing water, the handwriting will disappear without a trace. Interestingly, even if you don't wipe it, the handwriting will naturally disappear after a few hours or a day. If you close your notebook after writing, your handwriting can last for about a month.
As soon as this pen came out, it was immediately welcomed by many people. Can be used to make some temporary notes and records, and write repeatedly in a notebook or a piece of paper; Can be used to draw a route on the map, make some temporary marks and comments when reading, and do not defile books; It can also be used to draw pictures or sketch manuscripts, which is very convenient to modify. Even the tailors in the garment factory like it very much, because it can draw lines on the cloth instead of chalk to prevent the cloth from getting dirty. Compared with the pen, it highlights its advantages and unique functions.
Relief pen Have you ever seen a blind man write? Their pens are actually awls. It is inconvenient for them to make small, regular eyes with awns on thick paper and then "read" by touching their fingers. Now there is a real pen for the blind. In fact, this pen is no different from ordinary fountain pen, except that the ink it uses is made of a special formula. When writing with it, the ink can quickly condense and form a raised three-dimensional relief line on the paper. It is much more convenient for blind people to read such words by touching them with their fingers. This pen can also be used to write the title of an article, which is very eye-catching and can leave a deep impression on people. (Let's talk about pens with special ink-automatic disappearing pens and embossed pens. )
In addition, in order to meet the special needs of people engaged in various occupations, people have also made some novel pens, such as ink ballpoint pens, colored ink pens, glass pen writing on glass, porcelain pens writing on porcelain, luminous pens writing in the dark, surgical pens for surgeons to draw surgical sites on patients' skin, etc. There will be more and more interesting pens in the future, which will make people's study and work more convenient. The pen family will be more colorful. Finally, I simply write a novel pen that serves various special needs. )

My little master loves me very much. Every time I finish my homework, he will put me in a stationery bag and let me have a good sleep in it. If I fall off the table, the young master will quickly pick me up and wipe the dust off my body with his hands.
However, sometimes the young master will get angry with me. I remember once, when my master used me to do his homework, he wrote too hard and the lead was always broken. He wrote and wrote, and he was angry with me. The master looked at me coldly, his eyes full of anger. The master looked at me and became even more angry. He threw me on the ground, leaving me alone, and then continued to do his homework with other mechanical pencil. However, the master has just finished his homework, and he continues to write his homework. When I saw the young master do this to me, I was so happy that I forgot my sadness just now.
