This is also a 600-word class composition.

Does the classroom have to be tangible? My answer is: not necessarily. My class is natural, and I have learned a lot here.

Butterfly is my teacher in this class. It taught me that "although the process of success is painful, we should still choose success, because the end of pain is a rainbow." Therefore, whenever I suffer from success, I tell myself again and again: "After the pain, there is a rainbow, after the pain, there is a rainbow ..."

In this class, the fallen leaves are my teachers. They taught me that "although the result is dust, it is also good, because we have cultivated the next generation, and we have declared our value to the world with actions." Although we are not outstanding, it is enough. " Therefore, whenever I go to any activity, I will choose selfless dedication.

In this class, Chrysanthemum is my teacher. It taught me, "I chose the lonely and withered autumn because I thought one step more than others." Who will have time to look after our faces in the spring when flowers are in full bloom? Only in autumn can I get people's appreciation and praise. Although the environment is bad, I have no regrets. " It was the chrysanthemum that taught me "think more and your life will be full of gorgeous flowers."

In this class, disaster is my teacher. It taught me that "disaster is what a person needs most in his life." Only by accompanying it on the road of life can he make a difference. " I know that' born in sorrow, died in happiness', so we should treat setbacks with a broad mind and treat life with an optimistic attitude. "Therefore, facing life, I always smile; Faced with setbacks, I don't face making a fool of myself.

…… ……

Naturally, this is also a classroom, which is the most precious in life and cannot be measured by money.

I learned a lot from science class.

Embrace nature, and nature is also a classroom.

When climbing into the clouds, it is a class, enjoying the majestic peaks, towering peaks, and even the mountains above Wan Li, and learning the perseverance of mountains. "There are hundreds of miles of snow in the ice, and there are thousands of clouds." Only mountains have this kind of enthusiasm. The eagle flies here and the river bends here. How many heroes in ancient times relied on mountains? Du Zimei's "Once you climb to the top, you will see that all the other mountains are short in the sky." And Li Taibai's "the danger is high, the road is difficult, and it is difficult to go to the sky" are all ambitions.

When I swam into the river and watched the waves rolling, I learned the national spirit. "If you don't see how the water of the Yellow River moves out of heaven, you will never return to the sea." How magnificent it is to break through thousands of miles. "A spring river never returns, the waves are exhausted, and a romantic figure through the ages", the Wan Li of the Yangtze River, the mountains and rivers on both sides of the strait, and the mourning apes solo, how dangerous it is. Rivers, like the journey of the motherland, come out of the rugged and eventually plunge into the sea.

When I visited the garden, I learned petite tenderness, willow spring breeze, singing and dancing, filar silk spring water pouring down, small bridges flowing water, which was intoxicating. Many poets also drowned here. Willow, warbler, lotus leaf and lotus flower are also mentioned in ancient poems. "The next day, the lotus leaf was infinitely bright, and the lotus reflected the sun in a different color." "Two orioles sing green willows, and a row of egrets go up to the sky." There is always an antique feeling. "Women in the garden talk about Goldman Sachs, while children in the pool hide phoenix trees. The more I see the moonlit night, the more I talk about the spring outing at dusk. "

In the faint forest, learn the soul of vegetation. Tao Yuanming loves chrysanthemums, sees through the world of mortals, and is honest and clean. There is also the gentleman's meaning in "Ailian Shuo", "Straight through the outside, not sloppy, fragrant and clear, graceful and pure, but not ridiculous from a distance", and integrity is eternal.

I learned the usual comfort when I stopped in the love of wild cranes in the countryside. A wheat wave rolled, a Yun Lan, a country folk song and a stream splashed. Have the charm of abandoning the world for agriculture. A good song, "A dead vine and a faint crow, a small bridge and a flowing water family, a thin horse on the old road, a heartbroken man at the end of the world at sunset", is not miscellaneous, nor is it expected to show much prosperity and grandeur. I just want to experience the simple farmhouse dusk, and the rain is just around the corner. Another song, "Fishermen on the river at dusk, bamboo wisps of smoke and bluebirds singing, blue waves rising from layer to layer, lotus flowers sleeping in the sunset", is very common, but more comfortable. Live in peace with the world. It also leads to the poem "Peach Blossom Spring", "The land is flat and spacious, and the houses are like this, with fertile fields and beautiful bamboo and mulberry. The bustling traffic, where chickens and dogs hear each other, including farming, men's and women's clothes, self-knowledge as an outsider, yellow hair hanging down and enjoying themselves, also depicts the sincere feelings of yearning for the world. "

When you climb to the top of the cloud, swim across the rolling river, come to the countryside, walk into the forest and have a look at the garden. You might as well appreciate the beauty of nature and understand its feelings. Think of the heroes written by ancient poets and write one or two poems to express your feelings.

"Yi Yun is surrounded by mountains, with towering trees, dangerous peaks and stacked stones, and flowing water with leaves. Therefore, the sky is green, misty and dusty in the stream, vaguely continuous, flashing trees and hiding flowers, occasionally revealing the Buddha's light of royal makeup, and snowing on the cliff all the year round. I am reluctant to return, and there are branches to lead, and the butterfly is happy. Miao Yousong, show his color, dangerous mountains and strong beams, show his strength. My old friend likes to live in seclusion. Now I am a wanderer, looking at the ravine and Ran Ran hiding cigarettes. "

Nature has not only a beautiful appearance, but also an inner one. I learned a lot when I saw many rivers and valleys. Nature is really a magical classroom.

Life is a classroom. As long as you feel it with your heart, you will get the truth of life.

On New Year's Eve, I enjoyed the fun with my family. At this time, the loud noise of firecrackers shook the whole earth, and the brilliance of fireworks set off the deep blue night. While people cheered, I was lost in thought: fireworks painted a beautiful picture in the air, depicting the beauty of the festival; Firecrackers interweave into a deafening symphony, playing a festive atmosphere. However, the brush is a pen, each pen is burned with a bunch of fireworks, and countless sparks are exchanged for extinguished flashes; That song was played one after another, and every sound was an earth-shattering firecracker, which was the process of a small gun from being ignited to falling with the wind. Their lives are short, but they left the brightest moment in the night sky and the eternal flash in people's hearts. I can't help thinking about life. In a short life, some people have become real passers-by in the world, and some people are diligent and dedicated, adding a wonderful point to the world. Even if this is wonderful and insignificant, it is enough to make you feel the value of life. ...

On that day, I gained a great truth of life. In ordinary life, I still feel the philosophy of life.

I am a nostalgic person. I can see in my drawer that old books and stationery are all crowded in this small space, and sometimes there are needles, threads and brains. I don't know why, I can't bear to lose them, as if there is a love between me and them. However, these messy old things often bring me a lot of trouble. So I finally decided to throw them away. The drawer suddenly became neat, and I learned to give up. When you make a mistake, try to give up all kinds of mistakes that you regret, and give up the inferiority and humiliation caused by mistakes; When you are frustrated, try to give up your frustration and despair, so that you can have a strong belief to support you to face the reality ... It is difficult to give up, but only by giving up can you start over and mature gradually. That day, I learned another important lesson in my life.

In fact, life is a classroom. In this big class, we constantly learn lessons and gain new knowledge; In this big class, we constantly enrich ourselves and refresh our lives. Open your eyes wide and let's explore the true meaning of life in the vast classroom.

When I was a child, I was timid and curious, and I was very fresh about everything. Sometimes I am a parent's pistachio. Seeing passers-by riding bicycles on the road and a gentle breeze blowing over me, I remembered the profound lesson of my childhood, riding bicycles.

I see the child next door riding a bicycle freely every day, very happy, enjoying it like a happy elf, and I always walk hard step by step. Later, I think I must learn to ride a bike.

Since I started riding a bike, I didn't know anything. I thought I would study for a few days, but it wasn't as long as I expected. I stepped on the pedal, gently stepped on it, but there was a sense of fear. Later, I asked my father to hold me, and I must hold me. I repeated it over and over again. I plucked up my courage and, with their encouragement, started cycling. Oh, I didn't expect to swing from side to side as soon as I rode it. It scared me to death. I rode down, but I didn't expect my father to let go, which caused me to fall and almost break my skin. Later, my mother looked at me so angry and said, "People sound like riding a bike. We have to go through many ups and downs. We must strive to cross it. Only in this way can we tide over the difficulties. " Encouraged by them again, I rode. Although there was still a letter that made my heart jump, I kept telling my father to help me, but I thought my father still helped me, but he didn't. I began to fly like a butterfly. It's not easy! I am a butterfly enjoying life. Finally, I finished the cycling task I wanted to complete.

I still remember a famous saying: bravely conquer everything, and it can even add strength to flesh and blood. Maybe that's what gives me courage.

I learned a meaningful lesson, which can accompany me to grow up and make me work harder and succeed.

Life is like an ocean, only a strong-willed person can reach the other side. This sentence actually tells us that if we are not brave, we can't face the difficulties of life.

Life is like a kaleidoscope, colorful. Classroom is a post station on the road of life and another teacher who gives us knowledge and philosophy of life. Life is full of "classes" Social morality is a special "classroom" in life.

Recently, I saw two advertisements, which made people feel the importance of life lessons, because these advertisements endowed us with the philosophy of life. The title of this public service advertisement broadcast by CCTV is: "Abandon bad habits and advocate civilization."

The first section is on the subway. Everyone is kicking a jar, afraid to kick it in front of them. At this moment, the jar kicked at the foot of a young man. Unlike others, the young man continued to kick out, but picked it up and threw it into the trash can.

The second paragraph is on the bus, where young people are sitting and only an old lady is standing on the bus! While others sit quietly in their seats. This time I saw the young man. He gave way and helped the old lady to her seat.

After reading this advertisement, I think we should all praise the moral behavior of young people. On the contrary, we should condemn the behavior of those onlookers. To revitalize China, it is necessary to establish such a classroom model from an early age, so that children can grow up healthily under the influence of social morality. Nowadays, the social competition is fierce, and people need not only skills but also morality to stand on the society.

In primary school, in the ideological and moral class, the teacher told such a story to fully illustrate this point. When a Japanese company was recruiting, several China college students who came for an interview walked into the personnel department and fell down with brooms and mops. At the beginning of the interview, several college students walked to their desks despite the mess in the room. At this time, the personnel manager immediately announced the end of the interview, and these college students were eliminated. What a tragic ending! If they have more public morals and manners. I'm afraid this job will belong to them.

This is also a classroom, a classroom where one lives. If we want to achieve something in society, we must be polite, civilized and abide by social morality. We will learn something in this class.

The second article

Nature is a profound knowledge. In nature, you will understand a lot, which is also the classroom of life.

Once, I was stubborn. I thought that only by combining the sound of reading, spacious classroom, hurried bell and books could I call it a classroom until I walked into another classroom in my life. ...

"Flowers are more and more attractive, and shallow grass can be without horseshoes." When this famous sentence, which sang a lot of tears in the Spring and Autumn Period, echoed in this vitality again, I realized that this class had already begun. When I opened my eyes, the little flower poked its head out of the green bush, showing its pent-up vitality and smiling brightly. New buds also appeared on the willow branches, and the infected wind wrinkled a pool of spring water, and the microwaves rippled away, and the slender willow branches staggered. The branches tease the pure water in various ways, which is also a ripple ... brewing and stretching, releasing the vitality of this small courtyard. Life is cheerful, and youthful vitality like this will never be exhausted. Recalling the setbacks you have experienced, why bother to be persistent? Laugh it off. I learned this kind of smile from this class. This is so-called optimism.

I don't know when the high temperature around me has made my mouth thirsty. Suddenly looking back, it was the hibiscus in full bloom in front of the temple. "The lotus leaves are infinitely green the next day, and the lotus flowers reflect different colors in the sun" seems to be influenced by the sun, and the lotus flowers are also flushed, which is more attractive against the boundless green leaves and better than the roses in spring. Drunk, rolling in the heat wave, lotus, and Li Bai's "clear water produces hibiscus, natural carving" are the joy of life, and how much have you realized? The original heavy heart seems to have unloaded all the burdens. I see. Let nature take its course.

With a light heart, I came to the yellow world, and the autumn, which was sadly sprinkled by poets and poets, was filled with the silence of "the lonely phoenix tree locks the clear autumn in the deep courtyard". Everything is horribly quiet, and I can't hear the sound of grass drilling upwards, and I can't hear bloom's trembling in my ear. At this time, the wind stopped its cheerful footsteps and walked carefully. However, only silence can express all this, and the heart gradually becomes pious. Nature breeds all things and lets them open up the world. In this law of the jungle world, "survival of the fittest" is the only rule. Watching life go away, I suddenly fear nature, feel my smallness, and have a new understanding in front of greatness. Sometimes, this class will let you know that self is also the truth of life!

Sigh that life is impermanent, and it is snowing all over the sky. White and transparent crystals will accumulate on the earth in a short time, suppressing all living things, covering every inch of land and falling on all buildings. The world is white, and the biting north wind continues to roar, which is spectacular. Time flies, when everything you see succumbs to the rain and appears in front of You Mei, the snow still can't succumb to its pride, and the cold wind is helpless in front of it. "In the former deep Xue Cun, a branch opened last night." A little Ogilvy was so fearless in the snow. What do you want to tell me in the class of life? Is it an indomitable struggle in a difficult situation? Grit your teeth and stick to it? Or are you determined to compete?

This is also the classroom, the classroom of life, it is called nature!

The third article

I have always looked at nature with a rigorous attitude of a student, watched it constantly change and learned from it. I think people are students all their lives, and naturally, it is the classroom.

I like watching the sunset on the stone bridge not far from home. Every evening, the sunset sets in a calm and beautiful manner. I indulge in its afterglow and breathe quietly. It symbolizes the end. Countless sunsets, countless dusk, I feel that the days have passed day by day, in silence. I began to cherish time, because time is invisible and sunset is visible. Every day I sit on the stone bridge and hear the sound of the river flowing. I think that's when time flies. It is the sunset that makes me know how to cherish time.

I like grass too. They are tenacious, vigorous and endless. I watch them struggle upward in the shadow of big trees, and I will think of those who can still create their own careers under the grand shadow created by their predecessors. That is an admirable courage and persistence. When the grass finally broke through the ground and showed its fresh green, I found the unknown power contained in their small bodies, as silent as a dormant volcano but enormous. It was the grass that told me to be brave and strong!

And ants. A small creature known for its spirit of unity and cooperation. It's really amazing for ants to move! They communicate with each other with slender tentacles and move giants with slender feet. I think of the advertisement of Budweiser beer, lifelike ants, carrying beer bottles and cooperating with each other. Unity is reflected in every detail. This group of lifelike ants, let me know what is true unity.

Nature is the most wonderful class. As long as you have the modest attitude that a student should have, what you have learned will permeate your mind.
