Blackboard composition

In daily study, work or life, everyone will inevitably come into contact with composition, which can bring our scattered thoughts together. Do you know how to write a standardized composition? The following is the blackboard composition I collected for you. Welcome to read the collection.

About blackboard composition 1 I did indoor cleaning this week. On the afternoon of March 24th, I finished the last class in the afternoon, and my classmates began to pack their schoolbags. I also picked up the broom and left many words on the blackboard.

Liu Xiuyun, our team leader, forced me to clean the blackboard, which would produce a lot of dust. As a man, I reluctantly lift the "heavy" blackboard eraser and wipe it hard and quickly. ...

I looked at these disappearing handwriting, and the intensity of wiping was less, and the speed of wiping slowed down. It seems that I have feelings for the blackboard full of handwriting and don't want to wipe it. In just a few minutes, I was reluctant to wipe because I hated mistakes, and now I am reluctant to give up because of nostalgia.

How many words are written on this blackboard? How many times did you wipe it? We can't remember it clearly, but she remembers it clearly, but she never confessed, just put on the coat of knowledge all day and took off its …

She dedicated her silent, meager and selfless love to us every day, but it accumulated over time and became our whole beautiful student days.

Looking at the settled chalk dust, I found that the blackboard had been cleaned by me. The blackboard took off her beautiful knowledge coat again.

Composition about the blackboard 2 Last week, the teacher asked us to publish a blackboard newspaper about the National Day, and this is my first time as the "editor-in-chief" of the blackboard newspaper, so I was particularly excited.

In the past, the general teacher would help us find layouts, illustrations and written materials, but this semester the new teacher asked us to find them ourselves, which added another task to us. According to this new situation, I rearranged the tasks of the students who participated in the blackboard newspaper work. First of all, I asked some students to collect articles about the National Day online, and asked other students to go with me to borrow books about the blackboard newspaper from Chinese teachers in other classes, so as to design the layout and illustrations of this blackboard newspaper.

The students looking for the article went smoothly, and they quickly determined the content. However, our team encountered difficulties in finding layout and illustration reference materials. Because the teachers we consulted told us that they usually look for pictures online, there are no books on the blackboard newspaper. Finally, we decided that the layout and pattern of the blackboard newspaper should be designed by ourselves. This work is actually very difficult to do, because we should not only draw beautiful pictures, but also ensure that we leave enough space for articles, so we all discussed it and decided to leave three open spaces for writing articles and draw pictures elsewhere, which seems easier to control.

When I started to publish the newspaper officially, I arranged the specific content according to everyone's characteristics. I asked a boy who is good at painting to draw a five-star red flag and the borders and lines of the article; Let a more careful girl draw some small flowers and other patterns beside her. And I am responsible for drawing characters, and another classmate who usually writes beautifully is responsible for copying text materials.

With the concerted efforts of everyone's Qi Xin, our blackboard newspaper was successfully completed. Because of our good grades, the second-grade teacher also entrusted us to help the second-grade students publish blackboard newspapers. To tell the truth, we are all a little proud!

About the blackboard composition 3 The traces on the blackboard can be erased, but the memories left in the mind from the blackboard can never be erased and forgotten!

Silkworms in spring will weave until they die, and candles will drain the wick every night.

Everyone says that school is our second home and teachers are our parents. I think it's true. Teachers have nurtured us, taught us endless knowledge, led us into the ocean of knowledge, let us step by step towards success, and feel the joy and laughter brought by success!

I have such a profound understanding now, all this is attributed to one of my primary school teachers, who made me feel the selfless dedication of the teacher!

I remember when I was in the fifth grade of primary school, several classmates and I went to school to make up lessons on weekends. I came to the classroom with my classmates. As soon as I entered the classroom, I saw the teacher dozing off on the platform. There is a pile of exercise books on the desk, and I only read half of them. At that time, my classmates and I saw it and thought it was the teacher who was lazy! So one of our classmates, willy-nilly, called out to the teacher and patted him on the shoulder. The teacher woke up, broke his hazy eyes, had dark circles around his eyes, and his face was obviously haggard. He was less energetic than usual, but at that time we were too careless to realize it and cursed the teacher for being irresponsible! When the teacher saw us coming, he immediately told us to sit down and read some books, do some topics, and then explain the topics to us at the top of our lungs. The teacher took a sip of chrysanthemum tea from time to time, cleared his throat, and continued to explain to us ... This half-day passed like this.

The next morning, the students came one after another, when I came. I saw the teacher sitting on the platform early, absorbed in correcting homework.

Ding Rinrin, the bell rings and the class begins. It is strange that the teacher hasn't come yet. The students are talking about it. As usual, the teacher has already started teaching, but today I have an ominous feeling. Fortunately, this time, the teacher came in. The teacher seemed to force a smile, so he apologized to us and began to give us new lessons as usual. The teacher's voice is still so loud, but it is obviously mixed with a little noise. Looking at the teacher like this, the boys who always love to talk in class are quietly sitting in their seats and listening to the teacher. The teacher wrote clearly on the blackboard word by word. Soon, a big blackboard was full of words, watching the teacher waving chalk on the podium. The tall figure was shaking in front of the blackboard, and suddenly the teacher fainted. At that moment, he still had a piece of chalk in his hand ... The students quickly called other teachers for help and sent them to the hospital. Afterwards, the substitute teacher told us that the teacher was ill, with a fever, a cold, a sore throat and a little anemia.

In order to make up for our delay in class, she bought some antipyretics in a hurry and continued to teach us until she fainted. At that time, my classmates and I cried. After school, my classmates and I spontaneously formed a team, pooled some money and bought a fruit basket to go to the hospital to see the teacher. At that time, the teacher was lying in the hospital bed hanging salt water. Looking at the face of a nearly retired teacher in her fifties, she saw the vicissitudes she had experienced. Her pale face seems to hint at the students. What did she pay? So that we can take the lead! I cried. How could I misunderstand such a good teacher? She was ill, but she insisted on giving us lessons, but we said she was resting and lazy. I shouldn't, shouldn't judge indiscriminately!

Teacher, you lit yourself with a candle, but you warmed us. Teacher, you are the sun, without you, we can't light it; Teacher, you are a lovely silkworm, spinning for people to appreciate, but not asking for anything in return; Teacher, thank you for your hard work, holding chalk and imparting knowledge on the blackboard. No matter whether it is cold or hot, you never throw away the chalk you have held for most of your life.

Hard work on the blackboard makes you full of peaches and plums, and the memories on the blackboard are reunited with yesterday!

After entering junior high school, teachers often write students' names on the upper left corner of the blackboard, which is called "drying table": some homework is not completed in time, some are late for class, and some are not serious about their work on duty ... The teacher said that these names are all small spots on our class's face, so some students often tease these students and name them "acne". I laughed at them too. Unexpectedly, I have been to the "sunburn platform" myself.

I am addicted to online games because of my light academic burden. Sleeping late every day, always waking up in the morning under the repeated urging of the alarm clock, often staying in bed, leading to being late for school. One day, I overslept, woke up at 7: 30 in the morning, rode to school after breakfast, and then rushed to the classroom at a speed of 100 meters, thinking that I just had to sit in the classroom before the teacher came to the first class. I didn't expect the teacher to start class, so I had to stand at the door of the classroom panting and timidly shout "report" The teacher didn't embarrass me, but said seriously, "Why are you late for class today?" Let me go back to my seat.

After class, the teacher called me outside the classroom and asked me why I was late. I wanted to tell a lie, but I finally told the teacher the reason. The teacher was a little angry, but he forgave me for telling the truth. He said earnestly, "You are late for school every day, and many students study in the sun in the morning. After a long time, your academic performance will fall behind your classmates. " My face was very hot, so I covered my face with my hands, as if I were baking on a fire. Glancing at the classroom, several students are looking at me curiously. The teacher is still slowly telling me the meaning of morning reading, and I am listening with my head down without saying a word.

How time flies! I don't know how long it took, but the teacher finally let me into the classroom. However, he wrote my name in red chalk on the "Sunburn Watch". The blackboard in the upper left corner is spotless, and my name stands out. My deskmate looked a little gloating, and several of my "enemies" also sarcastically said: "Xin-small acne. The word' new' on the blackboard is really dazzling. " I was speechless and ashamed. In Chinese class, I looked up at the teacher's blackboard, saw the bright red name, and immediately lowered my head, afraid to look directly at the blackboard; In English class, I was reading the words on the blackboard, and I caught a glimpse of the bright red name. Familiar syllables suddenly become unsmooth: in math class, the teacher asked me to perform on the podium. The bright red name in the upper left corner seemed to be a pair of eyes, which made me nervous and seemed to laugh at me: "Who told you to be late!" " A very simple calculation problem, I actually made a mistake.

I had a nervous day and came home at night. My mother looked at my eyes and asked me if I was sick. I had to smile and say, "Nothing." Seriously, I felt very tired and went to bed early, thinking, "I won't be late tomorrow, no, I won't be late every day!" " "This is my deepest memory on the blackboard. The bright red name in the upper left corner of the blackboard is like a ghost, urging me to do everything well all the time. Since then, I have never been late again.

About blackboard composition 5 100 years later, the earth is full of signs of pollution: smelly ditches, few flowers and trees, poor air quality, gray skies and deserts everywhere. In order to prevent the earth from being destroyed, scientists have made a blackboard that can protect the environment.

This blackboard can write crayons and chalk, and there are two holes in the middle of the bottom.

The first hole is used to suck all the dust. This hole won't make a sound when it sucks. If it sucks dust from clothes, it will never suck people in. In addition, the colors of inhaled dust are also divided into red, yellow and blue to confuse the colors. There are several buttons below! Red is to absorb all chalk or chalk dust, and green is to absorb some chalk dust.

The second hole is used to produce chalk. As long as you suck enough dust, you can make a lot of colorful chalk. If you have enough chalk, you can put it directly into the suction hole and dissolve it.

Everyone must protect our environment, let Mother Earth live a few more years, and don't use this blackboard to save our home! We should take good care of our home-the earth!

About blackboard composition 6 I am on duty today. After class, I picked up the blackboard and wiped it. The blackboard is tall, and I am small, so I jump to wipe it. I'll rub it here and there, and it'll be fine in a minute. I stood in the distance and looked, wow! The blackboard looks like a huge painted face. No, it needs repainting. But what if I can't reach the blackboard? Suddenly I had a brainwave and moved a small chair. I stood on a small chair, picked up the blackboard eraser, and wiped it from top to bottom, from left to right, in order. Clean the blackboard this time. Looking at the black blackboard, I was also happy.

About blackboard composition 7 "bell, bell, bell." When the bell rang, the teacher picked up the English book and walked out of the classroom. At this time, in front of the podium, I saw many English letters on the blackboard and thought: This blackboard will definitely affect the math teacher's class. So, I went to the blackboard and picked up the eraser, eraser, eraser! Clean the blackboard.

"Bell, bell, bell." When the bell rang, the teacher came into the classroom and saw the clean blackboard. Don't mention how happy he is!

About the blackboard composition 8 math class, the teacher wrote a lot of questions on the blackboard, ready to call the students up to answer. My deskmate was dozing off, so I gave him a push and said, "Hey, the teacher told you to clean the blackboard!" " "I saw this guy run to the podium, picked up the blackboard brush is a homework, the classroom was silent for 5 seconds, and then an uproar. ...

About blackboard composition 9 Today is the duty of our group, and I am responsible for cleaning the blackboard.

I will start from the bottom and gently rub it once, twice and three times. After a while, the blackboard below was cleaned, but when I looked carefully, there were still handwriting stains and many small white spots on the blackboard, so I had to wipe it again. Then, I began to wipe the middle, which was easier to wipe, but sometimes I came across some crayon prints. It must be defeated under the "great power" of rags and water. I moved another stool and stood up to clean it. I wiped it carefully. Yu Gaoyang (my classmate) suddenly stood on a stool with one foot and tried to stand up. I almost fell.

Alas! How thrilling!

On the blackboard composition 10, I passed the small blackboard again and couldn't help but stop. Rows of "10" tags are embedded with a "9" tag, which seems out of place. On the mark of "9", my name was on it, but I recalled my lip angle ... (Naturally, at first, the contents on the blackboard in front of me aroused the memory of "I". Write the contents on the blackboard in detail to give readers a clear image and arouse their thinking. )

Chemistry examination room for physical and chemical experiment operation skill examination. 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. (The examination process is described in detail, which highlights my respect for experimental facts. )

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. The invigilator wrote the exam results on the blackboard. Take care of the first paragraph and answer the origin of "9" )

9 points, my score in the physical and chemical experiment operation skill test is only 9 points, which is so big and dazzling, but it is so small in that row of "10" ... (Through the comparison between "9" and "10", I feel ashamed and small. )

All the students around me testified that my reagent didn't turn 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 matter is not over, but the teacher is asked to do experiments to prove his conclusion is correct. )

Once again, I was surprised at the result. After heating for a period of time, the reagent shows a pleasant blue color, and it is gently placed in the test tube ... (As a result, the reagent shows a blue color. The personification of blue highlights the pride of experimenters. )

"I still feel wrong." I persisted as always and took out the dilute acid for 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" still insist, the last test. )

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. "Hold your breath" and "stare" highlight my nervousness and the importance of this test. As a result, the test paper turns blue to reveal the answer, which is concrete and vivid. )

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. Facts speak plainer than words. My experimental process was correct, and I didn't give up. This is what I should be proud of. )

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. By not changing the score, I show my indifference. On the contrary, I am even more proud that "9 Points" shows the achievements and testimony of "I". )

"9" survived after all, and at the same time, the nine dots on the blackboard and the reagents that stubbornly refused to turn blue will 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. Deepen the main idea of the article, and stick to what you shouldn't give up in everything you do. )

This small blackboard and everything else will be my proudest memory and an inexhaustible motive force to inspire me to go on. Take care of the topic, sum up the above and point out the topic. )

The memory on the blackboard is beautiful and firm. The ending is concise and thought-provoking. )
