Description text of chalk

I believe that you will often come into contact with compositions, especially expository texts. Explanatory articles make people have a scientific understanding of the shape, structure, nature, types, causes, functions, relationships or concepts, characteristics, sources, evolution, similarities and differences of things through the explanation of objective or abstract things. How to write this type of composition? The following is an explanatory article about chalk that I collected for you. Welcome to share.

Description about chalk 1 Hello, my name is chalk. I am more than two inches tall, almost cylindrical and well-proportioned. There are many members in my family: white, pink, green, yellow … all these colors, of which white is the most common.

Our chalk family has brought a lot of help to people, especially in teaching: whether it is pinyin, the combination of Chinese characters, the addition, subtraction, multiplication and division of Arabic numerals, or the spelling of English letters into sentences ... We all try our best to write the most beautiful words on the blackboard and draw colorful pictures, just like a tour guide, leading people to roam in the ocean of knowledge and fly in the colorful sky. As we get shorter, children grow up and have more and more knowledge.

We let the blackboard eraser gently erase the lines and handwriting we wrote on the blackboard with our bodies. Countless tiny pieces of chalk fly in the air with the wind, and then slowly float down and settle down. We can't help but think of the teacher's hard work standing on the three-foot platform from spring to summer to autumn and winter, and the years when his hair was covered with moss and his temples were covered with snow. This spirit of selfless dedication is exactly what our chalk family wants to learn.

The teacher struggled to write on the blackboard and said, "We strive to prove our value on the track of life, so that we and the teacher can be spiritually integrated, turn into drops, condense into light and moist nectar, and give birth to flowers of knowledge;" It has also become a bright road, leading children to a colorful treasure house of knowledge. I want to shout to people: "I am chalk, and I have no regrets all my life!" " "

Explanatory article 2 on the chalk: "Fruit is noble, and the cause of flowers is sweet, but let me do the cause of leaves in the shadow of silent dedication!" " This is Tagore's famous saying. Chalk is a green leaf. I like chalk, maybe you will wonder: Why do you like chalk with so many pens, ballpoint pens, pens and brushes? Because he has the same spirit of silent dedication as Ye Zi.

Chalk is about one centimeter long. It is not as beautiful as a pen, nor as easy to use as a ballpoint pen. It wears a white coat all the year round, just like angels in white, even a little old-fashioned. Of course, there are white, blue, red and yellow chalk, which we call colored chalk.

Chalk is knowledge in the hands of teachers. Whenever new knowledge is injected into your mind, there must be a piece of chalk that turns to ashes after suffering. It is willing to exchange life for knowledge and teach us. Silkworms in spring will weave until they die, and candles will drain the wick every night. Ah! What a great dedication.

Chalk in our hands is graffiti and entertainment. We write on the ground with chalk and fight with pens. We can't feel its pain at all, but it still contributes silently. Let's play, let's play, let's play, even if it is smashed to pieces, we are not afraid at all.

It is an art for a painter to draw with chalk. Chalks of different colors have gone through hardships in the hands of painters and eventually become patterns. The painter made the chalk glow with infinite brilliance, and painting was born. It is pleasing to the eye.

When those students make achievements, when those paintings are praised by people, who can remember what made them? Yes, it is chalk, but it is quietly and bravely dedicated behind the students and painters. How great its spirit is.

Some people may say, "chalk is short and ordinary, and when it is used up, it is a pile of useless dust." I'm telling you now, you are wrong. Since ancient times, so many talents have been trained, and all we know are people with chalk quality. "Mao Zedong, Hawking, Huang Jiguang ..." Their dedication has no chalk.

Chalk is great and worth learning.

The most active person in our class is Wang Sicheng. He always looks indifferent. Anyway, he always jumps around like a monkey when playing.

The English teacher in our class changed the afternoon before yesterday, only to see a serious teacher wearing a black T-shirt come in. As soon as he came in, he shouted, "Everybody be quiet. Look at your homework yesterday. Really annoying! Wang Sicheng, you stand up! The homework is a mess! " When I turned around, Wang Sicheng was still eating melon seeds and eating leisurely! The teacher is even more angry. When the teacher threw chalk at him, he was still eating, and the students immediately burst into laughter. He is really brave.

Another time, we played a game of grabbing chairs in class, which made us burst into laughter. Of course, he is no exception. I saw him pick up a melon seed, then grabbed a lot of melon seeds and threw them away. Suddenly, melon seeds flew all over the sky. It all fell on the monitor, and now he is going to be punished, so he said piteously, "Teacher, I didn't mean to!" " "Of course, the teacher won't forgive him, so he took him to the office.

In a science class, he was still eating melon seeds and playing his own cards. The monitor of our class immediately wrote three pages about his crime, and he still ate melon seeds in an indifferent way. After class is over, he still walks and plays, so he can't help it.

This is the most active and naughty classmate in our class!

Explanatory article 4 on chalk "shua shua-"The chalk slides on the blackboard and writes neat lines on the blackboard. Broaden students' knowledge horizons.

Alas, the blackboard and chalk are really a pair of "brothers in trouble!"

Let's start with the blackboard. The blackboard has the spirit of self-sacrifice. In order to help students get good grades, it does not hesitate. Even if chalk smears itself with scars beyond recognition, it still stands at the forefront.

Chalk for the future of students, regardless of their own lives, even if it is smashed, it still persists. It is really "not afraid of smashing"!

The "brothers in distress" met. Both of them praised each other and were modest about their efforts. Chalk said: "Blackboard Man, you are almost' broken into pieces', and you are still on the front line. It's admirable. " The blackboard reads: "Chalk bro, your health is broken, you are still holding your ground and won't give up. You are a man, a real man, and I am ashamed! "

At this time, a wise man came up and said, "You both made great contributions to the world. Even if you gave your lives, you are all real heroes in our minds."

Yes, the spirit of self-sacrifice and selfless dedication, such as chalk and blackboard, isn't that what I want to learn? Our economy and technology are developing now, but our traditional virtues seem to have been forgotten by the world. Although chalk and blackboard are insignificant, they are selfless contributions to mankind and are our' role models'.

Explanatory article about chalk 5 Although I arrived at school early in the morning, time passed quickly and class was about to begin. The first class is English. English teachers generally don't have any blackboard writing, but there are many blackboard writing in the new class. This "good thing" happened to me-I am having a new lesson today. This is a bolt from the blue for me, which means I will eat more chalk dust when I clean the blackboard.

In class, I have been praying in my heart: the teacher writes less, the teacher writes less, the teacher writes less ... but my prayer is useless, and the teacher is still unwilling to "show mercy." Chalk is getting shorter and shorter, and there are more and more blackboard books; I am getting more and more disappointed. I know: when the teacher uses up a new piece of chalk completely, there will be no more blackboard writing, but then the class is over.

My savior has finally arrived-the bell is ringing. The teacher reluctantly put the chalk in the chalk box and announced the class was over. But I'm not particularly happy. Facing this blackboard, I am helpless. Finally, I got up my courage and started fighting. My left hand covers my nose and eyes, and my right hand picks up the blackboard eraser and shakes it on the blackboard.

The most terrible thing came-chalk dust flew all over the sky, but it finally landed on my hair and clothes. I was very unhappy, but I finally cleaned the blackboard.

I went back to my seat and "chased away" the chalk dust that fell on my hair and clothes with my hands. Inadvertently, I saw some small white things under the blackboard. Driven by curiosity, I stepped onto the platform and picked up those white unidentified objects. On closer inspection, it turned out to be some chalk heads. Maybe the teacher wrote too hard and the chalk broke.

I was at a loss: should I pick up these chalk heads and throw them into the garbage basket? Throw it away, I think it's too much trouble again; Don't throw it away. I'm afraid the health inspector will see it, and I'll deduct points for class.

I felt a little sorry for them when I threw the chalk head into the garbage basket. I thought: Why do you throw them into the garbage basket? Because they are incomplete? Or because ... I can't find the answer in my heart.

There are classes again. This course is math. But I'm not in the mood to listen to the teacher. I am absorbed in this problem. Suddenly, I heard the sound of chalk breaking because I was sitting in the first row. I thought: Is it because this piece of chalk fell to the ground, so it should be thrown into the garbage basket? I still don't know the answer.

After class, I went to the podium, ready to face the baptism of chalk dust. When I faced the blackboard, I thought of the answer-the answer was that I was wrong. Chalk is produced to make it easier for teachers to impart knowledge to students. But when we gain knowledge, chalk is disappearing little by little. We finally finished learning knowledge, but the life of chalk is over.

Although the life of chalk is short, it has been serving us all my life. Not only do we not appreciate it, but we also respect it less. How hateful this behavior is!

About the explanation of chalk 6 chalk must be known to everyone. Like a small white stick, it is two inches long.

Chalk's life has been dedicated to mankind. From the moment they came into being, his life began to count down. So the life of chalk is very short. When the teacher writes with chalk, the tail of the chalk gradually becomes shorter, and finally there is no chalk or only a little left. Even so, chalk has no complaints.

Some people compare teachers to hard-working gardeners and teach us knowledge. Yes, the teacher is like a piece of chalk, giving us tireless teaching. Like a bright lamp, it points out the direction of life. Teacher, your voice is sweet, kind and vivid. Sweet as a clear mountain spring. Kind as a flowing stream, vivid as a rushing river and sea.

Chalk has devoted all his life to mankind. Sacrifice ourselves and let us learn more knowledge. The teacher dedicated his youth to his career and guided us in the right direction.

I like chalk and its white color. I admire chalk and its selfless dedication. I admire people with chalk spirit.
