Chalk Praise A box of chalks lay quietly on the desk. One of the slender pieces of chalk was held by the teacher in his hand. "Squeak...squeak..." The chalk was on the blackboard. Moving, gradually, it became a dot. When the teacher finished writing the last word, the chalk was completely sacrificed, and what was left was just a line of knowledge. When the words were erased with a black eraser, what was left by the chalk The traces also disappeared and turned into falling powder.
Suddenly, I understood the life of chalk.
On the table in front of the blackboard, there are many chalks scattered here and there.
Almost all of these chalks are coming to the end of their lives, and some are even small and not worth mentioning.
"Ding Lingling", the class bell rang, and the students quickly ran back to their seats, straightened their chests, waiting for the teacher's arrival.
The teacher strode in, put the documents on the table, and started the lesson.
The teacher picked up a piece of chalk that was just big enough to hold, turned around and wrote on the blackboard for us.
"Swiss, swish, swish," the chalk turned into white granular objects. After leaving its own traces on the blackboard, it disappeared little by little.
When this little piece of chalk writes the last word for us, imparts the last piece of knowledge to us, and completes its last task, it disappears.
What a great quality is reflected from this little piece of chalk.
That is - dedication! Chalk uses the spirit of obscurity to convey literary knowledge, mathematical analysis, English grammar and scientific mysteries.
A small piece of chalk also has a wonderful future. It exudes its essence every day and dedicates its short life. Dedication is a kind of selfless beauty. It is silent, but it is with us. around.
Wherever there are car sirens, there are police officers. No matter the wind, rain, snow, severe cold or heat, they stick to their posts. What they inhale is the exhaust of the cars, what they hear is The noise of the horn is the smell of exhaust gas, but in exchange, the traffic is fast and smooth.
Isn’t this also a kind of dedication? Chalk life, I finally understand you... Chalk composition

This is a tribute to you, how great you are, I praise you, chalk... A 400-word essay on the use of chalk as a metaphor for people
Expand all I am already a sixth-grade student, and chalk is a common thing.
The body is more than two inches long, round and cylindrical, very well-proportioned, very hard and brittle.
White chalk is the most common, and the rest are colorful chalks.
"Things are rare and valuable." Some students do not cherish the large number of chalks, and they break or fall off after writing. Then take another one and let it be trampled into powder.
Chalk has given us a lot of help, from Chinese pinyin to English words.
From horizontal to vertical to Chinese characters. , from Arabic numerals to addition, subtraction, multiplication and division, it writes the most beautiful words and draws colorful pictures on the blackboard without complaint.
It is like a tour guide, leading us to swim in the ocean of knowledge. There are a lot of fruits picked in the orchard.
The longer the chalk is used, the shorter it becomes. As it is used up, we grow up slowly, and more knowledge continues to enrich my mind.
p>The chalk silently let the blackboard eraser gently erase the handwriting left by its body, and countless thin pieces of chalk scattered down.
Someone wrote. Quote: “The teacher’s hair was dyed white by the numerous chalk writings.
"Very vivid.
I think of the teachers who allowed the students to embark on the journey of life on their shoulders from spring to winter, from hair full of black hair to snow on the temples. This is like the selfless spirit of chalk.
We also want to be people who work silently like chalk.
The white body is only eight or nine centimeters long, and the flawless appearance seems to tell us. ——Its heart is as flawless as this white dust.
A piece of chalk may not be able to write many words, but a slight rub is enough to remove a small edge of it.
However, even for such an ordinary piece of chalk, the production process is a bit cumbersome. You must first turn the limestone into chalk, then mix the chalk with water, stir evenly, and then pour it into the mold to solidify. Can be made into a piece of chalk.
Over the years, teachers have used chalk to leave knowledge points one after another on the blackboard. To this end, the white chalks have contributed their bodies.
The chalk and the blackboard were rubbing violently. In an instant, each piece of chalk turned into "dust", some remained on the blackboard to spell Chinese characters, and some fell down.
The falling dust covered the teacher's hands, and the flying dust stained the teacher's temples.
However, the teachers never complained, or even complained or sighed.
p>Thousands of hard work is just for the last stroke, and after many polishings, it is just to contribute to yourself.
Throughout the day, the chalks come one after another, just to help us present the knowledge more clearly.
Maybe there were traces of them on the blackboard, and they were there over the years, but once they were wiped off, they disappeared.
Chalk, I praise you, I praise you for your contribution on the blackboard, I will always remember you! Every time I walk into a futuristic classroom, a noisy scene catches my eye.
A group of girls were discussing in whispers in the sunshine, occasionally letting out a few loud laughs; the "nerds" in the classroom were still so serious about feeding their brains with literature.
But in the classroom, the noise that broke through the silence suddenly broke out among the naughty boys! But the tool they used to explode was the humble chalk head.
Although its name is still chalk, it no longer has the slenderness. Seeing the piece of chalk that the boy threw on the floor, and the piece of chalk that was stepped on under his feet, I felt a sad feeling in my heart. Fa, I returned to my seat without saying a word, glanced at the unnoticed chalk heads on the ground, couldn't help but sigh, and shook my head... As the *** sounded, a class began... I Watching the teacher select a slender piece of white chalk and swipe it on the blackboard in a long way, another little chalk head was born.
I also know that another chalk head is going to be destroyed.
I deeply discovered that we really ignore too many "small" ones. We no longer miss them because they are small, they stay away from life because they are small, and they are forgotten by people because they are small.
A small seed, it is inadvertently abandoned by people, but it can break through the hard foreigners, break through the blockage of hard soil, and stretch out the buds of hope towards the sun.
"Wildfire never burns out, but the spring breeze blows it again."
I not only remembered a long-lost song "Wild Lily Also Has Spring".
That time, I understood the life of chalk.
It is like a star, which no longer shines as bright as a star because of aging, and like a flower, which loses its beauty because of aging and falls.
However, stars do not leave behind exquisite works and lovely images. Flowers are not the same fragrant and beautiful. Even if they are just a flash in the pan, some people still watch them at night with candles.
Then! The chalk head is different and has left its body on the blackboard, but it is older and smaller.
But concentration is the essence? ! Chalk uses the spirit of obscurity and the hands of teachers to convey literary knowledge, mathematical analysis, English grammar, the infinite mysteries of science and the moral understanding of society.
It! It is worthy of being a friend in the academic career - chalk. A small piece of chalk also has a wonderful future. It exudes its essence every day and devotes its short life until it is old.
The teacher is a hard-working gardener who uses sunshine, rain and dew to cultivate the students to thrive, but I suddenly had a daydream and suddenly felt deeply that chalk is like a small earthworm, which loosens the soil for us and makes us happy. Literature has been better delivered, shouldn’t we own it, love it, and praise it? should! You really should! The life of chalk, I finally understand you...

Expand all When chalk is mentioned, I believe everyone will say dismissively: "Chalk is nothing."
"Yes, chalk is not It's nothing, but it's this inconspicuous thing that spreads culture and sacrifices itself.
Chalk has made a lot of contributions to mankind throughout its life. In the classroom, you can often see naughty children hitting people with it or breaking it into pieces. In their eyes, it is useless. How do they know that they must be used to learn words and knowledge? It is dedicated to people selflessly and fearlessly, but some people look down upon it. It requires very little from people but gives a lot to them.
Aren’t teachers also such people? You spend your whole life thinking about students and spending a lot of effort for them. Who else but students can experience this kind of love? A teacher is a beacon that never goes out in students' life path, and a big umbrella in the storm.
Teacher, I love you, I love your spring breeze-like love for your students; Teacher, I respect you, I respect you for your knowledge, aren't you just like the chalk that has contributed to mankind throughout your life? You will always be the big umbrella in the hearts of your classmates. Chalk spends his life as a human being and you as a student. You value your students more than anything else and you worry about your students all the time.
You are like the spring rain that waters the flowers of the motherland. The chalk spreads culture and sacrifices itself. It is very content.
Because as long as it makes a little contribution to mankind, it will be satisfied. You exchanged your youth for the students' knowledge. You think it is worth it. For us, you are willing to do anything.
Chalk! I love your simplicity and your dedication.
At the same time, I also admire my teacher. I also feel a spirit of dedication from you! ...A composition about blackboard, podium, chalk, and chalk eraser
One day the blackboard and the blackboard eraser met together, and they both said that they have great abilities. The blackboard said to the blackboard eraser: "I have the greatest ability!" Because without me in the world, people can’t attend classes and learn knowledge, so I have the greatest ability!” The blackboard eraser said to the blackboard: “My ability should be the greatest. If you don’t have me on the blackboard, you won’t be able to write anything when it’s full! There are no other words. Who do you think is more capable?" They kept arguing. You said something, and I said something. Finally, I used chalk to persuade them to stop arguing. But they still refused to obey anyone. In the afternoon, the blackboard eraser and the blackboard saw each other. There was a teacher who was writing on the blackboard. Suddenly he discovered a typo. The teacher looked everywhere for a blackboard eraser, but there was still no trace of the blackboard eraser. The blackboard eraser was so proud that he looked a little pretentious. He smiled and said to the blackboard: "Brother Blackboard, you Look at my abilities. Look! Without me, people are going to die! Brother Blackboard, what do you think? Suddenly one day a group of construction teams came and looked at the blackboard and said, "This blackboard is erasable." So it was smashed." There were only two crashes, and the blackboard shattered. The proud blackboard eraser said to the blackboard: "Brother Blackboard, you are no longer useful, so people smashed you, but I am still safe." The blackboard eraser said He looked very proud. Day after day, year after year, the hair on the blackboard eraser has slowly fallen out, and the hard shell has gradually rusted, but he still lies there motionless. This story tells us Everyone has advantages and disadvantages. You should learn from the strengths of others and correct your own shortcomings. 500 yuan for a chalk composition using metaphors for others
"Chalk" is unknown, and others have never paid attention to it or protected it. , and it makes no complaints and selflessly lets people use it until the end of its life.
It leaves only some white ash.
It is - chalk.
It always goes unnoticed.
At school, in the classroom, it fell to the ground, and no one picked it up and put it back on the table.
Instead, step over it.
Its body was shattered like sand and stones, and a gust of wind blew it and sent it to a distant place... In fact, there is a kind of people, they use chalk to resemble it. .
They are teachers.
Teacher, what a common name! But, teacher, what a sacred name it is! Teacher, she paved the way for our future. She is selfless and hardworking.
She worked hard for her children and taught us the principles of life every day.
Every night, the children are already in sweet dreams, but where is the teacher? I am leaning on the table, correcting my homework by the light of the desk lamp! Teacher, she was afraid that we wouldn’t understand what she was talking about, so she kept talking over and over again until her voice was almost hoarse.
Which student’s grades have improved and who is the happiest? It's her, the one with the smile, the teacher.
Look! On the teacher's forehead, a few wrinkles are deeply imprinted on the teacher's head and on my heart... Chalk, isn't the spirit of selfless dedication the spirit of the teacher? She never complained, and she never regretted, because she sacrificed herself for others!
The Pen family pen is the writing tool used by everyone when they are cultivating the cultural field. We use the pen every day to practice calligraphy, composition, drawing, and calculation.
However, do you know about this huge family of pen? Let me tell you.
Pens are generally divided into two categories: hard pens and soft pens.
Speaking of the family history of the pen, I am afraid it is as old as us humans.
Tracing back to its origins, as early as ancient times, "pens" appeared in human life, which were just branches and sharp stones used to count or make marks.
In the slave society, people discovered that the hair on animals can absorb water, so they came up with a way to fix a small amount of animal hair on a bamboo tube to write. This is a writing brush.
According to the different raw materials of the pen tip, it can be divided into sheep hair, wolf hair, etc. The emergence of the brush greatly saves recording time and is more portable and practical.
How many literati used it to paint pictures with various brushes, leaving behind famous works and calligraphy treasures.
After the Qing Dynasty, a new type of pen appeared - the fountain pen. This is a new member of the pen family. They are more than ten centimeters tall, wearing metal or plastic coats, shiny metal heads, and rubber A belly full of "ink" is enviable.
The fountain pen is the pride of the pen family. It is practical, beautiful, writes smoothly, has clean and even lines, and is unmatched by other pens.
With the changes of the times and the development of culture and science, pencils developed from graphite pens have become economical, simple and practical. In addition to soft and hard thickness, there are also rubber-tipped pencils, movable pencils and pencils. Thin lead pencil, this kind of pen is commonly used by primary school students.
Nowadays, the pen family has suddenly flourished, and many new faces have appeared, such as chalk, ballpoint pens, crayons, art pens, colored water pens, etc., all kinds of exquisite, smart, beautiful, and practical pens. There are many kinds of pens and eyes, they are updated day by day and are widely used by people.
The scope of use of pens is becoming more and more extensive. Nowadays, pens are not only used for writing letters and taking notes. You see, girls use eyebrow pencils for drawing eyebrows, and engineers use computers for drawing. electronic pen, etc.
Don’t humans often say: “The pen and ink shock the heaven and earth, and the article weeps ghosts and gods”? I believe that with the rapid advancement of science, the pen family will continue to be transformed, updated, and developed, and its functions will become more and more complete, playing a huge role in human civilization.
================================== Since Cai Lun invented paper in the Eastern Han Dynasty, various pens have Various writing instruments—pens came into being.
The pen family has prospered: writing brushes, pencils, ballpoint pens, fountain pens... These pens have spawned various descendants, but the most commonly used pens are still fountain pens.
Fountain pens can be regarded as a major category of pens.
According to the way of storing ink, it can be divided into two categories: dip pens and fountain pens.
As the name suggests, a dip pen requires the tip of the pen to be dipped in ink to write. Sometimes we simply call it a dip pen.
Because of its unattractive appearance, simple structure, troublesome writing, and inconvenience to carry, it has long withdrawn from the stage of history.
Nowadays we use fountain pens that can store ink.
Because of its fluent writing, easy 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 pen tube, a nib, and a pen cap. The pen tube contains a small "ink bottle" capsule. When absorbing ink, just press Squeeze the capsule to expel the air, then insert it into the ink, which will absorb the ink.
When writing, the ink in the capsule flows from the tip of the pen to the nib. The nib of the pen is made of wear-resistant metal, which is thin and durable. It is not like a quill, which becomes thicker after writing too much.
The most expensive part of a pen is the nib.
Fountain pen nibs are divided into three categories: gold nibs, iridium gold nibs, and steel nibs. Among them, gold nibs are the best, followed by iridium gold nibs, and steel nibs.
The gold nib is made of gold mixed with silver and copper. The more copper it contains, the harder the gold nib is.
Both the iridium tip and the steel tip are made of stainless steel.
Both gold nibs and iridium nibs have small round particles, but steel nibs do not.
This is why steel tips are not as durable as gold and iridium tips.
That small round particle is an iridium alloy, which is called a metal "positive agent". It is very rare and very wear-resistant. It can withstand ink erosion and corrosion every day without being washed away.
This is also the secret to the durability of a good pen.
================================== I am an ordinary automatic pencil.
The little master takes me to school every day and uses me to calculate, draw, write, etc.
However, I have not always "followed" my master. My father and my grandfather played a big role.
Let’s talk about my grandfather first! I’m afraid there’s no one like my grandfather who doesn’t know this.
At that time, my grandfather could buy it anywhere, and even now, some people use it.
However, compared with me, grandpa is still very backward.
Okay, I won’t hold back anymore. My grandfather is the “famous” wooden pencil. You will definitely say: “What’s so great about wooden pencils!” Don’t underestimate my grandfather. In the past few years, it was an indispensable writing tool for people! Grandpa is made of wood, with a pen core inserted in the middle and painted green or various colors of paint on the outside to become my grandpa.
Grandpa’s pen refill is made of lead. When you buy it, you have to cut it out and sharpen it. Then you can sharpen it after you use it. You can buy it after it is sharpened. Although it is inconvenient, it is the only way.
Year after year, day after day, my grandfather got old and it was time to retire. At this time, my father took my grandfather's job.
My father is much more "advanced" than my grandfather, but there is still a certain gap between him and me. During the few years of "working" for the little master, the master liked him very much.
Dad is more beautiful and convenient than grandpa. Although the price is more expensive, he is still loved by people.
Dad’s “working principle is very simple: put in a piece of lead with the same thickness as the ballpoint pen core, and sharpen the lead on the pencil sharpener at the top of the pen cap, and that’s it.
This is much more convenient than grandpa. You only need to change the lead at any time, and it is OK. Compared with grandpa who buys it after use, it is much more affordable.
But gradually, dad’s problem also disappeared. When it came out, it was slow, the pens were sharp and dark, and the little master lost confidence in his father.
Slowly, I appeared in the little master's pencil case, and my father and grandpa were the same. Same, retired.
I have a decent name: Mechanical Pencil.
As the name suggests, I am of course automatic, but the "working" principle is still the same as that of my father. How much.
Put the lead in, press the little cap on it, and the lead will come out.
However, even if it is called a "automatic pencil", it has a different secret. Just this lead... What is this lead...
