Write a composition about the blackboard in 400 words. There is a blackboard in our classroom, which is dedicated silently and is our good partner.
There are about three blackboards.
5 meters long, 1.
8 meters wide.
Every time after cleaning, the blackboard shines, giving people a comfortable feeling.
It has a "mouth", which is flat and long. It is very "gluttonous" and specializes in eating chalk.
It has a lot of chalk on its mouth.
This blackboard is very important to us because it faces us and contributes knowledge to us.
So we never scribble on it, and we never get it dirty.
In class, the teacher dressed him in colorful clothes, and many red numbers, white characters and blue letters jumped around his face. After class, we prepare for its next class performance.
Because this blackboard has been with us for a long time, we have developed strong feelings with it. It is like our big sister, with rich knowledge. It is like our little sister, and it deserves our protection and love.
Ah! Blackboard, respectable blackboard, you don't hesitate to dedicate your rich knowledge to us ordinary primary school students, for what, so that we can get into a good middle school and a good university in the future and complete our career! Blackboard, for us, you'd rather let chalk scribble on your face. You endured the pain, so you patiently taught us a lot of novel knowledge and learned a lot of life lessons.
Thank you, Blackboard, we will always remember your resounding name-Blackboard! ...
It's sad to ask about the arrival of autumn in about 600 words. However, walking on an empty path and listening to the sound of the wind blowing through my hair made me feel scared for the first time. Looking up at the sky, watching the falling leaves helplessly, I suddenly felt my nose sour. I named him Memory.
Sometimes, memories are beautiful, just like leaves belong to trees, and sometimes, memories are silent, just like leaves belong to the wind.
Why leaves fall silently, because there is wind ... why leaves fall, because of pain ... leaves leave because of the injury of trees, and wind is only the healer of injuries. However, the leaves are simple, and they have not been comforted by the wind until the end, but the wind is still persistent. He doesn't want to give up the leaves, and there is always only one person in his heart. Even if he loves her very much, he can't change the silence of the wind. He will wait forever, just like a leaf, everyone has his own piece in his heart. No one can get in, no one can get out, just like leaves will stay forever, and the wind will always pursue the silence of the wind, without words and shadows. He doesn't expect to keep the leaves awake, without hatred or resentment, but she always fantasizes that there is only one year left in Qiu Lai's summer, her heart hurts only in an instant, and her tears only fall in an instant. Therefore, the leaves don't want to live without laughter. She wants to leave the clouds, and the wind blows the leaves away again and again. The wind wants to save the broken leaves ~! However, the leaves will never let go of the days when there are trees, although she thinks that she can forget the leaves without trees, as if there is nothing, so let the wind take her to fly. Wherever she goes, the leaves are free and ethereal, the wind is sad, and the leaves drift away with centrifugal separation. The sad tree is heartless, and the leaves fall, leaving her with heartbroken thoughts. The wind is soft and strong, and she just wants to leave the leaves with centrifugal injury, leaving her thoughts and thoughts in the treetops of Ye Fei. Hanging with a leash, the wind broke my heart, and my heart flew away and the leaves were scattered. There are no ripples and tears, the wind is clumsy, and the leaves are frightened. There is no place to complain about the wind coagulation and the wind sadness.
Ups and downs of leaves, broken dreams, broken cold and cheerless ... Wu Ye leaves are broken, and there are no tears on the trees.
The wind that comes and goes, the dream that blows, but the swaying hentai is dead, the leaves have fallen, and the trees are ruthless. What is hope and what is dream? ! One by one, the wind blows the leaves off, and the wind says, "Fly gently. Leaves belong to the earth, the wind blows them down, and the cycle is endless ... leaves are my favorite. What about you? " Spring has come, the earth wakes up and flowers are in full bloom, but I like green leaves best.
Leaves can be seen everywhere, on flowers, on branches, on the ground ... the shadows of leaves can be seen everywhere.
Leaves, such ordinary things, have extraordinary uses.
You use flowers as ties to make them more beautiful; You are also very useful to plants. You are equivalent to the respiratory system of plants.
Leaves also have the greatest ability to carry out photosynthesis, breathing in carbon dioxide, but spitting out fresh air.
Although you have done this, you are still unknown.
With the coming of summer, there are more leaves on the trees.
When the ruthless sun scorched the earth, you held up an umbrella to let people take shelter from the rain under your shade, but people still forgot you, but you didn't feel bitter about it.
Because you always have an idea in your heart: human nature is good.
But do you know that some people are insatiable? They cut down trees for their own selfish interests and pollute the environment.
In autumn, your faces have changed.
Some blush, like drinking a lot of red wine and getting drunk; Some people have indigestion and sallow complexion, and even people are thinner than yellow flowers and can't afford to fall to the ground.
Although the others are green, they have lost their usual vitality.
Autumn can be watched, but when people admire it, they still don't raise their proud heads.
In winter, you all fall down and put beautiful clothes on the ground.
When your life is about to disappear, turn it into spring mud to protect flowers and fertilizer for trees, and still do not forget to make the final contribution to mankind.
Ye Zi, although people have forgotten you, you still beautify everything around you in obscurity.
Ye, I love you! I like leaves best. What about you? -Postscript Ye Since this spring, I have inadvertently observed Ye's life.
Spring seems to be Ye's childhood.
In this blooming season, the leaves quietly show their green faces.
On the branches of various trees, there are tiny leaves everywhere.
Although the leaves are small, they also add a lot of vitality to spring.
Later, Ye gradually grew up.
In hot summer, leaves are like a big green umbrella, which blocks the burning sunshine and provides people with a shelter from the wind and bites.
Although leaves are not as bright and beautiful as flowers and cold-resistant as pines and cypresses, people still love them.
Just like Ye's middle age.
Then, cool autumn came.
At this time, Ye's old age arrived.
Harrison became yellow and haggard.
Some leaves come to the end of their lives and are mercilessly blown off the trunk by the wind, flying in the air like yellow butterflies, and then falling to the ground.
Some were trampled by people, some were made into cut leaves by children, and some were collected and processed into good fertilizer for crop growth ... In this way, Ye silently dedicated his life.
Spring makes spring full of vitality; In summer, give people shelter from the wind and rain and prevent mosquito bites; In autumn, Ye gave his life selflessly ... Students, what do you want to do when you see how Ye spent his life?
Writing a Universal Blackboard Composition Universal Blackboard Every time I see the teacher cleaning the blackboard, chalk dust flies all over the sky. I hope to invent a future blackboard to make it more convenient for teachers to attend classes.
The future blackboard I invented is made of unbreakable glass, like a big screen.
On the left of the blackboard, there is a microcomputer. There are three buttons on the computer: the first one is the Enter key, which can be pressed to display what the teacher wants to write on the screen.
You can also adjust the subjects! There is a theme adjuster next to this button. After the Chinese class, the teacher put the tone head on the Chinese language to make the input words become clear and neat Chinese characters.
Similarly, you can display numbers or English in math and English classes.
The second is to clarify the key points.
Its function is to clear up typos.
The third is the zoom-in and zoom-out key, which can enlarge the displayed text with one click and double-click to reduce the displayed text.
In this way, even nearsighted students can take off their glasses and see the words on the blackboard clearly.
There is a hidden radio on the right side of the future blackboard.
This radio is connected to a hidden computer by ultrasonic waves. If the teacher wants to write something, just say it, and then press enter, the radio will be quickly transmitted to the computer by ultrasonic waves, and what he wants to write will come out.
This is the future blackboard I want to invent. I must study hard and turn this future blackboard into reality.
The memory composition blackboard on the blackboard is nothing more than the place where teachers write class notes and calculate formulas.
However, for me, the small world on the blackboard in my memory connects the hearts of my classmates and teachers.
"Hey? Who posted this? " When I first entered the classroom one morning, I saw a long white tape on the blackboard, which separated the left side of the blackboard by about half a meter.
I turned to look at our blonde head teacher, but I wasn't surprised to see her.
That's weird.
When I was in the fourth grade, I went to school with my father in Houston, USA.
The head teacher is kind and beautiful and often talks with us.
When I came back from physical education class that day, I found that there was an extra line on the blackboard: Congratulations to my classmates, I'm going to have a baby! The signature at the bottom belongs to the head teacher.
The whole class suddenly boiled up.
The head teacher told us that she would write down the baby's "latest information" in this half-meter space to let everyone know about his situation.
Since then, it has become our habit to sit in front of the blackboard and watch the news every day.
"On February 9th, I felt as if it kicked me.
""March 1 1 day, we know she is a girl! " "March 17, I hope she has blonde hair, too.
""On April 22nd, her name was Sarah, which sounds good! "... in my memory, there are new words in the small world on the blackboard every day. Whether it is the result of going to the hospital for examination or just the feeling of the class teacher, it is different every day, but the excitement and joy are revealed between the lines.
When reading, we share the happiness of the class teacher.
"May 8th, classmates, starting from tomorrow, I'm going home to recuperate ..." This is the last message on the blackboard.
Many people cried, so did I.
After the teacher left, the message kept flowing on the blackboard, and no one wiped it.
How much we like our head teacher! After graduating from the fifth grade, I went back to China.
Sitting in the present classroom, the blackboard in front of me often overlaps with the one in my memory.
For me, the message on the blackboard not only lets me know the growth of teachers and children, but also symbolizes that the head teacher likes us and treats us students as family.
Oh, yes, in my memory, the message on the blackboard on May 8 has the last sentence: "The teacher loves you!" " "
A composition describing a classmate cleaning the blackboard 100. Just change this person's name. First of all, I saw the dense words written in black and white and thought: cleaning the blackboard this time is not as simple as last time! I picked up the blackboard eraser and started to wipe it from below. I did it once or twice in sequence ... and it was finished soon.
I looked back and saw faint handwriting on the blackboard, thinking that my arm was so sour, forget it! Another idea is that the teacher will write tomorrow and the students can't read it clearly. The red scarf on my chest seems to say to me, "Don't just think about yourself and others.
"I wiped it again. Layers of ash floated on clothes and sleeves like snowflakes, and the bottom blackboard was finally cleaned.
Then I started to wipe the middle. I straightened my arm and wiped it with my toes. Although my arm was very sour, I still insisted on rubbing it. Slowly, I'll wipe the middle and then the top. I moved the stool carefully four times and finally cleaned the whole blackboard.
Chalk dust fell on my head and body. I dusted off and smiled at the black blackboard.
Write a 50-word composition with blackboard, chalk and eraser. Every classroom has chalk, blackboard brushes and blackboards.
They have different postures, their strengths and weaknesses.
When they are silently contributing, there is no complaint, just doing their own thing.
Chalk is one of the most elegant figures. It has many brothers and sisters, including yellow, blue, red, white and green.
Drawing and writing depend on it, and it also has a selfless heart, turning itself into tiny powder; Turn yourself into a painting; Make yourself a knowledge point; Make a word for yourself.
But it didn't complain, just left silently. It is like a candle, which lights itself and others.
The job of the blackboard brush is to help the blackboard "bathe".
Its shape is rectangular like a blackboard.
This is the dirtiest of the three of them. Whenever I help the blackboard "bathe", I get dirty all over, and no one helps it clean up the dirty things.
Some people didn't even read it, but it didn't complain about anyone, just did its job seriously.
The memory composition on the blackboard is 600 words. Narration.
Don't repeat it, 3Q
In that classroom which exudes cultural flavor and teachers are conscientious in teaching, students are immersed in reading, and the whole classroom is filled with a long-lost retro bookish atmosphere, which is ancient and lasting, and became famous for a while, making countless candidates join in it. Maybe we are about to face the same fate, and we will join the battlefield with the fate and future of blood and sweat, so we will feel so empathetic and feel the greatness established by the ancients in the same examination room and atmosphere.
I can't help looking at the blackboard in the distance. Before I saw what I had planned in my heart, even fools knew it was "the words of sages", I saw a huge black distorted figure. I saw him swinging from side to side, twisting the girl, bending his back into an S-shape, writing hard, and writing white words with his hands on the dark board. Dancing words flooded into my eyes and brain like vivid knowledge. I seemed to feel that the white words on the dark blackboard filled my brain and turned it white.
Unclear white hands continue to fly on the blackboard, shaking out such vivid white characters on the dark blackboard like convulsions.
Sasha vujacic, sasha vujacic! The sound of students' pen tips is mixed with the sound of white chalk hitting the blackboard. Looking at this scene, I feel a sigh in my heart. It is not only us but also the teachers who suffer for our exams.
This blackboard carries too many memories. There are white chalk characters with infinite feelings of teachers, and there are too many feelings on them. Unfortunately, black and white are the best match.
Just as the system of students and candidates is the best match, the words on the blackboard can only be written in white. Even with other colors, it's a pity that it's just chalk. No matter how gorgeous the color is, you can't draw it with a pen of other colors, because there is nothing to wipe for you, so you can't do it on this blackboard, just like a teacher's duty, you have to teach and educate people on it.
So the blackboard and the teacher form an educational paradise, which makes people sad and happy. What's the fun? At least we haven't gone to hell! So all this has become a rule, a template.
Blackboard. Maybe that's where your name comes from. You are destined to be in this rule, in education, just like the rules you must implement in life. Blackboard not only has its function, but also teaches us with its own blood and tears, and tells us with its designated purpose and unchangeable destiny.
You gave us too much on the blackboard. Facing you, our memories are like a river. We can't forget you and everything above for a long time. Those words, known as sages, have written the traditional monotonous brilliance on your dark body. I think this is what the education system really wants to teach us! ! ! Facing everything, facing the teacher's watery eyes, what did I read? I answered the insurmountable words written on the podium. My memory of the blackboard originated from the second grade.
I vaguely remember that it seems to be the first composition class in Grade Two.
As * * *, the class began.
At that time, Mr. Weng, the Chinese teacher, began to draw a big round face on the blackboard, with God's eyes and a big mouth, which was very arrogant.
The lack of nose made this lovely face suddenly feel inferior. Well, what can we do? The content of this lesson is to draw a nose! As the last stroke falls, the students' eyes have already flashed with light.
Teacher Weng's smile deepened, and a crisp and pleasant voice sounded in our ears: "Who will try first?" Followed by shouting "I'm coming!" "Please me!" * * * has left his seat uneasily.
Teacher Weng is also happy to see the students so active.
Please go to Xiao C (a pseudonym). Sighs came from the audience and echoed in the classroom.
I saw Xiao C covering his eyes with a cloth, standing in front of the blackboard and slowly rotating for three times, but not firmly moving towards the round face, picking up the chalk, which seemed very confused.
"Little C, draw a little to the left!" "No, a little higher!" All kinds of comments filled the classroom.
Xiao C in front of the blackboard seems to be hesitant and hasn't put pen to paper for a long time.
..... After a while, I saw his hand turn around his eyes for a while and then stopped, and a nifty round nose appeared in front of us.
"Ha ha!" "Wrong painting!" Some of the students under the stage patted their bellies, some bent over and laughed, and some even wiped their tears ... and little C on the stage had to touch the back of his head shyly and walk back to his seat with laughter.
Then, the confident little H (a pseudonym) went to the front again ... Many years later, I still remember that the ending of the composition was "The game of drawing the nose continues, and there are bursts of laughter from time to time in the classroom ...".
Maybe who won or lost at that time has long been forgotten, but I still remember that I was really happy at that time ... The memory on this blackboard has long faded on the blackboard, maybe it was covered by countless exercises, maybe it was erased by the old blackboard, but it was fixed in my memory forever as early as that class.
We probably can't find that innocence, and sometimes we can only grope slowly in our memory and try our best to recall it.
But it can't really appear in our lives. Our life is covered with competition, troubles and heavy thoughts, so we can never find that innocence-a real happiness.
I like the topic "Memory on the Blackboard" very much, because it reminds me of a game called "Drawing Nose".
Compared with now, we will not be happy with this kind of game, but when we shout, it may be our precious memory of standing on the blackboard.
Composition on blackboard, platform, chalk and eraser One day, the blackboard and eraser met together and said that they had great skills. The blackboard said to the eraser, "I have the greatest skill!" Because there is no me in the world, people can't go to class and learn knowledge, so I have the greatest ability! " The eraser said to the blackboard, "My ability should be the greatest. There is no me on the blackboard, and I can't write any other words when I am full of words. Who do you think is the greatest? " They quarreled endlessly. In a word, I finally persuaded them to stop arguing with chalk. But they still refuse to accept anyone. In the afternoon, the eraser and the blackboard saw a teacher writing on the blackboard. Suddenly found a typo. The teacher looked for the eraser everywhere, but there was still no sign of it. Eraser is proud and pretentious. He smiled and said to the blackboard, "Big Brother Blackboard, look at my skill. Look! " Without me, people are anxious to death! Brother Blackboard, what do you say? "Suddenly one day, a group of people from the construction team came to the blackboard and looked at it. They said, "This blackboard can be erased and smashed. "The blackboard was smashed. The proud eraser said to the blackboard, "Big Brother Blackboard, you are really useless, so people smashed you, but I am still safe." The eraser looks very proud. Day after day, year after year, the hair of the eraser has slowly fallen out.
Composition: Memories on the blackboard 1: Names on the blackboard It's time for self-study class again, and the blackboard has taken over the constant task of self-study class-remembering the names of undisciplined students.
"I hope the students on duty don't remember the names of anyone in our group. If they do this, the whole group will be punished.
"I prayed in fear and trembling, with a cross in my heart.
"Squeak, squeak," the student on duty wrote down the name of another classmate. I suddenly looked up and calmed down: "Fortunately, I am not a classmate in our group!" Memory 2: The teacher's blackboard writing Although I have been in the fifth grade, the "creaking" version of that book still echoes in my ears, intact.
This Chinese teacher is quite famous in the school because she has become our substitute teacher and head teacher.
I remember: on the first day, she began to give us lectures and write on the blackboard, which shocked all her classmates.
Her handwriting is so good that I don't even want to blink.
At this moment, I suddenly understood that the teacher is famous for her beautiful calligraphy.
We don't doubt this, she told us on the blackboard! Once, the teacher gave us a class and unconsciously deviated from the topic, talking about "four continents and five oceans."
"When we listened with relish, the teacher spoke passionately and wrote' Four States and Five Seas' on the blackboard.
When the students saw these six words, they quickly said, "Teacher, your four continents and your continent are misspelled! When the teacher saw it, he used his quick wits and said, "Students, do you know what I am going to do in this class? I just want you to find the wrong word.
After listening to the teacher's words, the atmosphere in our class became active again-Memory 3: Different methods of solving problems. In math class, the math teacher wrote a topic on the blackboard: "Uncle Liu surrounded a semi-circular chicken farm with a fence 15.7 meters long.
What is the area of this chicken farm? After discussion, the students came to the conclusion that the perimeter should be calculated first, then the radius should be calculated, and finally the area should be divided by two.
I am in a hurry. I have another way to solve this problem. I quickly raised my hand: You can also divide the length of the fence in a semicircle by pi to calculate the radius, then calculate the area, and finally divide it by two.
This triggered a heated discussion among the students. Some are right and some are wrong, and there is no conclusion yet.
There are many memories on the blackboard, sweet and sour, colorful.
Passing the small blackboard again, I couldn't help but stop. Rows of "10" tags are embedded with a "9" tag, which seems out of place.
Above the "9" mark, it is my name, but I remind me of the chemistry examination room of the lip angle ... physical and chemical experiment operation skill exam.
There is a classmate standing in front of each experimental desk, who is busy but has an answer.
I am one of them.
After heating for a period of time, the reagents of the same group of students are all blue, indicating that the sample to be tested is copper oxide.
And mine has been cooked several times, and it is still transparent.
Although I have a lot of doubts, I decided to respect the experimental facts and fill in "toner" on the test paper.
My hunch came true, and the invigilator successfully approved my paper. After a short stay, he made a big cross on "Toler".
Soon, she turned around and wrote "9" on the blackboard.
9 points, my score in the physical and chemical experiment operation skill test is only 9 points. In that row of "10" scores, it is so big and dazzling, but it seems so small ... all the students around me testify that my reagent has not turned blue.
Without saying anything, I hurried back to the experimental platform, picked up the unknown black solid and asked the teacher to do the experiment.
The result shocked me again. After heating for a period of time, the reagent showed a pleasant blue color, and it was gently placed in the test tube ... "I still don't think it's right.
"I insisted, as always, and took out the dilute acid I used to do the experiment.
The teacher brought the PH test paper, and the acidity turned red and the alkalinity turned blue, preparing for the final and final exams.
I held my breath, stared at the test paper, and slowly dipped into reagent bottle, a rich and heavy sapphire blue that could not wait to spread, until it swallowed the whole test paper, deep, deep.
The answer is obvious. It turns out that the dilute acid I used in my experiment is alkali.
I was right from beginning to end.
Besides, I never gave up.
The students all think that the "9" on the blackboard should be changed to full mark.
But I just smiled and didn't say anything, so let this "9" stay on the blackboard, because it is the result and witness that I insist on.
Is it different from other "10" integrals? No, nine points can be that perfect.
"9" survived after all. At the same time, the nine dots on the blackboard and those stubborn reagents that refuse to turn blue will also be engraved in my memory, reminding me to stick to what I should not give up, such as objective facts that no one can refute.
This small blackboard and everything else will be my proudest memory and an inexhaustible motive force to inspire me to go on.
The memory on the blackboard is beautiful and firm.
"Who cleaned the blackboard today?" As soon as the head teacher entered the classroom, he stared at the blackboard and frowned.
The eyes of my classmates swept to me. I jumped up from my seat, rushed to the blackboard, picked up the eraser, and tried my best to erase the handwriting left by the chemistry teacher last class.
It's done. I smiled and walked to my seat, but as soon as I sat down, the teacher said, "It's not clean enough. What did the students think later? " As the class draws near, the students have returned to the classroom one after another. All eyes shot at me like bullets, and I seemed to be beaten black and blue.
I lowered my head, gritted my teeth and walked to the podium. I picked up a wet rag and rushed to the blackboard.
As soon as I rubbed a small piece, the old class's voice rang in my ear again: "Go down.
Don't wipe it. How can I have class in the future if you wipe it like this? "I really want to clean the blackboard, not for you! I hate being misunderstood all my life.
Tears fell unwillingly after being wronged.
And you gently pick up the blackboard eraser, gently pat off the original chalk dust on it, and gently wipe the blackboard.
There was a cough in my ear.
You cover your mouth and frown slightly, but you just want to clean the blackboard so that we can see your blackboard more clearly.
Two more coughs.
Fragments of time slowly came to me and pieced together.
I thought of my mother.
My mother used to be a teacher.
When I was very young, I occasionally heard my mother cough slightly. ...
Xiaoling is on duty today.
After the first class in the morning, she saw that the blackboard was full of numbers, so she picked up the blackboard and wiped it.
She wiped the words on the bottom of the board first, only to see her right hand holding the blackboard eraser hard and wiping it quickly.
White chalk fell on the back of her hand, hair, clothes and shoes like snowflakes.
Slowly, the words below were finished, and she straightened her arm and continued to wipe the words above.
Then she stood on tiptoe and couldn't reach it. She played a few times and wiped it a few times, but it was still not clean.
So she moved a chair and stood on it to clean it.
Touching the place where the schedule was drawn, I slowed down and wiped it carefully.
There are fewer and fewer white words on the blackboard, and the black background is getting bigger and bigger, like a hard-working farmer cutting down the harvested rice, revealing a large area of black land.
Xiaoling moved the chair three times and finally wiped the whole blackboard clean.
At this time, her hands and clothes were stained with white chalk dust, but the blackboard became clean again and she could continue to serve her classmates.
She dusted herself off and smiled at the shiny black blackboard.
