Mathematics is everywhere in life, and we can only acquire knowledge by careful observation and discovery. I remember every day after school, I like to watch the retractable door of the school open and close, and I am very curious. At the same time, I have a question: Why is this retractable door so flexible? I was puzzled until I learned the unit "Understanding Graphics" in a math class. The original parallelogram is unstable and can be deformed, while the overlapping parallelogram can be expanded and contracted. Telescopic doors in schools use this principle. The problem that once bothered me has finally been solved! What a relief!
There is a lot of knowledge hidden in life. As long as mining and development, from obtaining problems to solving problems, is the process of acquiring knowledge.

Today is the first election since junior high school. The campaign draft was prepared yesterday, and it is planned to be a "blockbuster" today. However, a few minutes before the election, I became very nervous and kept praying: God bless, I must run for office!
Shit! It's my turn What should I do? I forced myself to calm down and start my campaign speech. But in the process of speaking, my legs have been shaking slightly and my whole body is cold, alas! Still nervous.
Finally, I finished my speech and stepped down. While listening to others, analyze the gap between yourself and others. I have an ominous feeling that I will lose the election-although I don't believe it.
The teacher announced the result, and as expected, I lost the election. Looking at the joy of other students, my heart is sour.

There will be an English exam next class. I turned over English books again and again, with English words in my mouth, eager to get good grades in the exam. & gt My deskmate laughed at me for being possessed, and I was unmoved: I repeated > insurance!
The test paper was handed out, so I read it quickly, but I actually reviewed it! So I wrote a book without hesitation, and it only took me twenty minutes to finish it. Check it again carefully.
At noon, I ran to the office building to see the scores and searched for a long time. Finally, I found my paper in a pile of papers with a bright red "100" on it. There was a burst of surprise among the people looking for the newspaper. Looking at the surprised faces of the students, my heart is full of sweetness.
I have only tasted a little bit of the ups and downs of middle school, and there is still a long way to go. No matter what you encounter, you should keep a rational and clear head, don't be carried away by victory and become conceited, and don't be heartbroken and depressed by failure. In this way, we can successfully spend our junior high school life.
May our beautiful junior high school life not be eclipsed by a little thing about you and me!
Life Diary Part III: 400 words of junior high school life composition
Junior high school life is full of happiness, distress, confusion and sadness. Too many emotions are integrated, and the short junior high school life becomes simple and complicated, which makes people worry and unforgettable.
Going to junior high school means that you have grown up. Now you are not the "little princess" or "little master" that everyone loves to protect. It means that you have your own ideas and freedom, and you are no longer a person who only listens to your parents and has no opinions. Although there is freedom, life is out of control; Although > has grown up, there are some things I can't do by myself.
In the past, it was natural and easy for teachers to help solve any difficulties in school. Learning is not very urgent, even if you can't control yourself, at least you have strict parents around you. Being pampered at home, paying no attention to anything, and having parents around. Life is orderly.
But in junior high school, everything naturally changed. It's like entering a strange world. Small things are solved by themselves at school. The school is also very nervous and has a lot of homework. When I can't control myself, my parents won't care too much. Because they think they should learn to be conscious when they go to junior high school. At home, she is not the spoiled "little princess" she used to be. You should pay attention to everything yourself, because they say you should have your own opinions when you grow up. In this way, junior high school life is spent in chaos. There is no order in daily life.
In junior high school life, when I meet something that makes people feel distressed, the sad thing always tears myself. Always smile in front of classmates and pretend to be strong. In fact, laughter just masks my sad side. Now I understand the meaning of "tears in laughter". Because there is no broad shoulders like my parents before. That shoulder is like a warm stove, just like Stray Kids found a home. But now, I have no home to go back to. I only cry when I am sad, and now I have no shoulder to lean on. Because the person leaning on the shoulder is the old me.
Everyone says that life in junior high school is free and easy. I naturally expected to grow up quickly and enjoy junior high school life until I got it. It turns out that the price of freedom is sadness. This price is too high and too painful. I can't accept it at the moment.
Life Diary Part IV: Junior High School Life Composition 400 Words
Living in the magnetic field of life, moving at high speed. After countless seasons, young people have learned a lot. The four seasons are playing their own life marches on the natural stage. We also grow up day by day, in which we feel the baptism of life.
Flowers bloom in spring.
The breeze gently brings spring. In this season, flowers are scrambling to open, grass has just emerged from the ground, and wicker has pulled out green shoots. Is this a competitive season? Teachers often say that we are flowers in spring and grow in the sun. In school and life, we strive for our own achievements and different goals in our hearts. There is also fierce competition in our study and life, just as we strive to be the first blooming flower in spring.
I learned about competition here.
Green grass is like summer.
I saw flowers in full bloom and looked down at the lush grass. It didn't bow its head in the storm that just passed. Although the rain beads are still hanging on the grass's head, trying to make it yield, the grass still insists on waiting for Sun's rescue. It knows that when the sun meets again, it will not be oppressed by others. Can the indomitable spirit of the grass not touch you? Do you also deeply feel the greatness of life?
Here, I learned to have hope and never give up.
The fifth chapter of life diary: 400 words of junior high school life composition
Accompanied by cool, comfortable and pleasant autumn wind; Accompanied by uncontrollable joy; With the surging waves in my heart, I stepped into the gate of No.3 Middle School with great curiosity. Thus, colorful and interesting junior high school life appeared in front of me.
I believe that every student has different views on the new junior high school life!
In my opinion, junior high school is our most important stage. It is the time when we bloom the flowers of pure friendship, the sky where we fly happy notes, the place where we realize our colorful dreams, and the time when we yearn for freedom and bloom our youthful dreams like flowers!
In the morning, when the first ray of sunshine gently touched the town, I rubbed my eyes, dressed quickly and came to the bathroom. With the sound of the tap, the biting ice water pulled me out of the fog. After breakfast, I flew out of the house like a happy bird and ran to the hall of knowledge! Fast forward. In my opinion, the most important thing in junior high school life is to gain knowledge and friendship!
Ah! Look who this is. The figures of several female students in front appeared on the road, and from time to time they gave a ringing laugh like a wind chime. I hurried behind them, and it turned out to be those girls who love to learn. They didn't bother me at all, but invited me to join their team more enthusiastically. So, we swim together in the ocean of knowledge and explore the mystery of algebra; The absolute value and the same column term are discussed. Talk about the tranquility and beauty of Bai Niao for a while; The profundity of English grammar; Small cells have an ordinary but extraordinary mission; Is Qin Shihuang "an emperor through the ages" or a tyrant? The geographical latitude and longitude lines make me feel extremely wonderful. How happy we are to study together, talking and laughing!
In my opinion, junior high school life is so colorful, but it is also like a bottle of five flavors, ups and downs. Now the homework that was finished around six o'clock can only be finished around eight o'clock. The burden of all subjects has gradually increased, and the usual leisure weekends have been replaced by my rushing figure. I really envy other children playing downstairs and making innocent laughter. I look forward to being a child. However, I am no longer a simple-minded pupil. I want to work hard.
Try to win at the starting line of life. I want you to meet my old friend. Three years later, we will definitely look at each other with a smile, encourage each other with a mature attitude, and continue the next journey of life.
In my opinion, junior high school life is a fertile ground for us to bloom pure friendship flowers, a sky for us to fly happy notes, a place for us to realize colorful dreams, and a time for us to bloom our dreams like free flowers.
Life Diary Chapter 6: Junior High School Life Composition 400 Words
Day after day passed, just like a stone thrown into the lake, but it sank with a bang. Time also slowly sank to the bottom of the lake of life. From time to time, several bubbles pop up and playfully swing from side to side. After a while, time was broken, so silent that it sank and disappeared.
The most interesting thing this week is the biology class on Tuesday. The biology teacher speaks quickly. When teaching, she often teaches us a few tips that are very useful in life. She is a person who loves life, but the classroom is full of explosions.
This is a classroom, but it is not like a classroom. Everyone who loves answering the phone is answering the phone. Some were scolded back, and some were still answering the phone. The head teacher is here! ! Suddenly there was silence between heaven and earth, as if there had never been any sound. There are not a few people who talk to teachers in biology class. This kind of class is really fast and noisy. In a blink of an eye, the bell rang and several "playing" hearts left in a hurry. The teacher asked angrily, "Did I say class is over?" However, they are unrepentant and ignore the teacher's anger directly.
Slowly, I got into the habit. The students ran out when they heard the bell, leaving only the teacher staring at the students with a book. Finally, they slowly opened the door and left without saying anything.
Life Diary Chapter 7: My Life Diary
Some people say that people who like writing are always too sentimental. I agree with this sentence. Although I am not a good writer, I like to record the details of my life. Because in my records, I can express what I want to express at will ... On this day of willful return, I find that I have no yearning and passion for spring, because the arrival of this weather makes many rheumatism patients feel pain, and it also makes me feel a mood gap, even if the grass grows outside and the warblers fly.
Presumably, colleagues will not fall in love with this beautiful spring girl because her foot is hurt. Even if the scenery is beautiful, what she appreciates is missing if she is not in the mood. I often wonder, what is a person's mission? Our bodies are so fragile that he accidentally stepped on the uneven road and broke his foot. When I came back from the hospital, I was in a cast and on crutches. For him, this seems to be a shameful thing, because he said, "It's nothing to do like a disabled person!" " ! Probably don't want to accept this reality.
During this period, colleagues in our department took good care of him. In order to reduce his activity opportunities, our boss reported this situation to his superiors, and applied to the personnel department for the first floor dormitory, and allowed colleagues in the department to pack meals and send them to the office and dormitory for dinner. The humanized management of the company and the support and understanding of the administrative department have given us the greatest convenience and support. Living in such a big family, such an atmosphere, such warmth, has already dispelled the breath left by the cold winter. At this time, "spring blossoms" seems to be the most expressive word.
Compared with our boss, our help is negligible. She is considerate to her subordinates. We can see that as long as she is free, she will take over the task to take care of her injured colleagues. In the morning, she always sends her colleagues to dinner first, and then goes back to the dining hall for breakfast. When the weather changes, regardless of her foot pain, she gives her most needed hot compress to her injured colleague, which helps his blood circulation. She always helps others in their difficulties and cares about the people around her. Her carefulness and thoughtfulness are not only reflected in her work, but also in her life. She never asks for anything in return, only follows her own wishes. I really have never heard of such selflessness. Although I haven't known each other for a long time and I'm not so familiar with my life, I have seen many unusual attitudes and attitudes towards things in these short months of work contact. I tried to write an article about her deeds and the inspiration she gave me with what I saw and felt, but I failed, because the language was pale and weak at that moment, or maybe my pen was not strong enough to carry the word "she" that I admired.
On the afternoon of March 8, when I got off work, it was raining heavily outside, so my injured colleague couldn't ride back to the dormitory. He wants to wait until it rains less. Chen of the computer department saw that he hadn't left yet, so he said to get off work together. At that time, I was already walking on the stairs. I don't know what will happen in the elevator. I only saw Chen carrying an injured colleague downstairs to see his momentum. Although there is only one flight of stairs, it is not easy for Dignā ga's thin body to carry a big man downstairs. When this scene was staged in front of my eyes, every nerve line of mine was touched. When I went down to the lobby on the first floor, I said to Xiao Chen, "Comrade Lei Feng has worked hard." He smiled shyly and answered my words: Hehe ...
Difficulties are like this rain, no matter how big it is, it can't dampen our confidence and courage to challenge it, but we can still solve it. This is power ... the three of us shuttled through the rain, I held an umbrella, and Xiao Chen helped my injured colleague. ...
