Gradually silent,
Rain and fog enveloped the sky.
Is slowly spreading out, writing blue sky.
As a result, the sun came out,
Rain and fog are urgent to avoid,
The warm sunshine shines on Qian Shan,
The sky turned blue,
The blue sky,
What brings us joy is the composition "Composition Blue Sky" in the second grade of junior high school. The bird is standing on the branch,
Singing happily,
Seeing birds singing so happily. We also gradually began to frown,
Smile!
Pan Baosheng, No.3 Middle School of Zhongshan County, Grade Two.
My sky is blue. On the third day of 600, the sky is changeable, the rosy clouds are beautiful, the blue sky and white clouds are pure and the lightning is fierce. And my junior high school life is like this sky. There are ups and downs, which make people memorable.
I reviewed the final exam of this semester very carefully. But the truth is so cruel: I lost 40 points because the computer scoring statistics were inaccurate. Looking back on junior high school life in the past two years with a report card is like a painted colored paper.
Since the first day of junior high school, I have put on an appliance to correct my teeth. Now I have been caught by my classmates and have been calling me my nickname. I thought to myself, "forget it, let them keep screaming ~" but it didn't last long. Physical education class, because I can't play basketball, my classmates laughed at me again. I thought, "Don't worry too much. In life, who won't grab each other's handles and play jokes on each other? "
By contrast, ridicule is nothing. Failure in the exam is the most important thing.
Before the first final exam, I didn't review carefully at all. The exam results were not satisfactory. In the second semester, I reviewed carefully, but I lost points because of carelessness in the exam. Last semester in Grade Two, I lost my score for the first time because of computer statistics errors. This time, for the same reason, my grades have dropped greatly. Review the previous exams and review the bitterness of review. My confidence completely collapsed. After all, in the two years of junior high school life, my total score in the big exam has never been above 400. But before the exam, I arranged scientifically and studied hard. At that moment, the sky in my heart suddenly turned into a black color.
It's always sunny, and there are still many comforting things in life. The encouragement of classmates and the teaching of teachers. Praise from parents. Let me feel comfort and encouragement when I am depressed.
I also have a very important "job" in my class-managing the computers in my class.
I have been a computer administrator since the first day of junior high school. This coke broke me. I thought, "With my sense of responsibility, what is a computer?" Unexpectedly, a week later, a projector was installed in the classroom. This really scares me. After all, this is the first time to use it. Sure enough, it took a long time to understand because of lack of experience.
In class that day, the teacher came up and said, "Turn on the computer and projector, I want to use it." This really worries me. Helpless, I had to pretend to go up. When the teacher talked about the exam on the platform, I was reading the instructions and operating. The teacher looked at it and said, "Hurry up!" I was sweating with anxiety, and the students in the audience whispered, "Look, he is still bluffing!" " "I quickly glanced at the instructions. Finally, I found the section "Link mode of switching projection to computer". Finally, five minutes later, I successfully switched the projection link to the computer. Back in my seat, I proudly said to my classmates, "everything is difficult at the beginning!" " "
Bitter is sweet. At the final award ceremony, I won the honorary certificate of "Best Class Cadre". Holding the award, I returned to my seat and said to my classmates happily, "Look, what else do you have to say?" After all, "plum blossom fragrance is not biting cold." It seems that as long as you work hard in the past, you can gain more today.
My colorful sky makes me feel the ups and downs of junior high school life. In this, I not only mastered more knowledge, but also learned a lot about being a man.
3. The composition "Walking under the Blue Sky" should be no less than 600 words. My sky is still so blue, as if it were washed away by the sea every day.
Blue and transparent, like a bright gem, reflected in my eyes, I can't help but reach out and want to touch the soft sky. Clouds exude a mysterious and strange magic, as if they can reflect what you want without reservation like a mirror.
I often walk in the endless sky, and sometimes I fantasize that one day I will walk in the blue sky, so light and happy. Sometimes I get lost in thought, thinking that I will face countless tests alone in the future.
In fact, when God gave birth to everyone, he designed a hurdle, a difficult, helpless and difficult hurdle. What we can do is not to escape, but to face it.
No one knows how difficult a person's road is. Sometimes, maybe even God is confused about how many people he has set up.
The sky is like a changeable book. When there are no waves, as long as you keep looking down, you will see many wonderful fragments, and even you will be surprised to understand it and dig it. When you lose this mood again, that book will become a book with nothing to look at and no characteristics for you. The sky, like that book, is always changing.
In the early morning, the rising lights in Ran Ran shine with afterglow, and the clouds are like colorful puzzles, spelling out the less dazzling light in the early morning. The sunshine at noon, like a child's smiling face, is so real that it burns the hearts of young people.
The sunset in the evening, under the command of the sky, jumped to dawn step by step, blushed and said goodbye to the earth! The scene at night is definitely different from that in the morning at this time. In the evening, the shining stars climb high into the sky, like a purple galaxy in my eyes, shining with countless rays, opening a perfect gap between heaven and earth.
Purple sky, yellow stars, everything is so quiet and beautiful. I think, an ignorant child greedily absorbs these favorite scenery in this pleasant time and space.
I, still lying quietly on the soft grass, close my eyes and feel silently. The fragrance of flowers brought by the wind, like being washed, makes my mind more pure and quiet. The wonder of the sky makes me have infinite reverie about this artistic conception, and I can't help feeling that under such a sky, people are actually so small.
Why is the sky blue? Whenever we look up at the weather, we often find that the sky is blue. Especially after a heavy rain, the sky is as blue as autumn water, which makes people feel relaxed and eager to fly. So why is the sky blue? The atmosphere itself is colorless. The blue of the sky is a picture created by atmospheric molecules, ice crystals, water droplets and sunlight. When sunlight enters the atmosphere, long-wavelength colored light, such as red light, has great transmittance and can penetrate the atmosphere and reach the ground. However, violet, blue and cyan light with shorter wavelength will easily scatter when it touches atmospheric molecules, ice crystals and water droplets. Scattered purple, blue and cyan light fills the sky, making it appear blue. Why is the sky blue, not green or red? First of all, you have to understand a truth: the things around us are colored only because the sun shines on them. Although the sun looks white, all colors: red, orange, yellow, green, blue and purple exist in the sun. There are so many colors in the sky, why do I usually only see blue? You might ask. If you think of light as a wave, you will guess the mystery. Light actually moves like a wave. Let's imagine a drop of rain falling in a puddle. When this drop of rain falls on the water, it will produce small waves, which will turn into larger circles and spread in all directions. If these waves hit pebbles or other obstacles, they will bounce back. It changed the direction of the waves. When the sun falls from the sky, it will continue to encounter some obstacles. Because the air that light must penetrate is not empty, it is made up of many tiny particles. Ninety-nine percent of them are either nitrogen or oxygen, and the rest are other gas particles and tiny floating particles. Exhaust gas from cars, smoke from factories, forest fires or volcanic ash. Although oxygen and nitrogen particles are only one millionth of a drop of rain, they can still block the path of sunlight. Light bounces off these small stumbling blocks and naturally changes direction. But so many colors of light change direction, why only see blue? You still don't understand. We must go back to the puddle mentioned just now. In a puddle, if a small wave meets pebbles, the water surface will be chaotic. However, if it is a "huge wave", like the one you hold by hand at the edge of the puddle, it may simply overflow from the stone and reach the opposite edge of the puddle unimpeded. Then, just like there are waves and wavelets, all kinds of light waves have different "waves", that is, wavelengths: but unlike water waves, they are invisible to the naked eye. Only very sensitive measuring instruments can accurately measure. According to scientists, the wavelengths of blue light and purple light are relatively short, which is equivalent to "wavelet"; The wavelength of orange light and red light is relatively long, which is equivalent to "* * * wave". When encountering obstacles in the air, blue light and purple light are "scattered" everywhere because they can't cross those obstacles, covering the whole sky-the sky, thus being "scattered" into blue. The scientist who discovered this "scattering" phenomenon is Rayleigh, who is in 10. He is also a Nobel Prize winner. The phenomenon of "scattering" can be used to explain the following phenomena: for example, the sky above you is blue, but where the horizon meets heaven and earth, the sky looks almost white. Why? This is because sunlight travels farther in the air from the horizon to where you are than it falls directly from the air-naturally, it will eat more particles along the way. These large particles scatter light many times.
4. Why is the sky blue? Explain why the sky is blue. Whenever we look up at the weather, we often find that the sky is blue, especially after a heavy rain, the sky is as blue as autumn water, which makes people feel relaxed and eager to fly.
So why is the sky blue? The atmosphere itself is colorless. The blue of the sky is a picture created by atmospheric molecules, ice crystals, water droplets and sunlight.
When sunlight enters the atmosphere, long-wavelength colored light, such as red light, has great transmission power and can penetrate the atmosphere and shoot to the ground; However, violet, blue and cyan light with shorter wavelength will easily scatter when it touches atmospheric molecules, ice crystals and water droplets. Scattered purple, blue and cyan light fills the sky, making it appear blue.
Why is the sky blue, not green or red? First of all, you have to understand a truth: the things around us are colored only because the sun shines on them. Although sunlight looks white, all colors: red, orange, yellow, green, cyan, blue and purple exist in sunlight.
There are so many colors in the sky, why do I usually only see blue? You might ask. If you think of light as a wave, you will solve the mystery.
Light actually moves like a wave. Let's imagine a drop of rain falling in a puddle.
When this drop of rain falls on the water, it will produce small waves, which will fall into a larger circle and spread in all directions. If these waves hit pebbles or other obstacles, they will bounce back and change the direction of the waves.
When the sun falls from the sky, it will continue to encounter some obstacles. Because the air that light must penetrate is not empty, it is made up of many tiny particles.
Ninety-nine percent of them are either nitrogen or oxygen, and the rest are other gas particles and tiny floating particles, which come from automobile exhaust, factory smoke, forest fires or volcanic ash. Although oxygen and nitrogen particles are only one millionth of a drop of rain, they can still block the path of sunlight.
The light bounced back from these small stumbling blocks and naturally changed direction. But so many colors of light have changed direction, why only see blue? You probably still don't understand.
We must go back to the puddle we just talked about. In a puddle, if a small wave meets pebbles, the water surface will be chaotic; But if it is a "huge wave", just like the kind of "huge wave" that you lift by hand at the edge of the puddle, it may simply overflow from the stone and reach the edge opposite the puddle unimpeded.
Then, just like there are * * * waves and wavelets, all kinds of light waves have different "waves", that is, wavelengths: but unlike water waves, their size is invisible to the naked eye, because they are unimaginably small, only one percent! You have to use very sensitive measuring instruments to measure accurately. According to the determination of scientists, the wavelengths of blue light and purple light are relatively short, which is equivalent to "wavelet"; The wavelengths of orange light and red light are relatively long, which is equivalent to "* * * wave".
When encountering obstacles in the air, blue light and purple light are "scattered" everywhere because they can't cross those obstacles, covering the whole sky-the sky, so they are "scattered" into blue. The scientist who discovered this "scattering" phenomenon is called Rayleigh. He discovered it about 130 years ago, and he is also a Nobel Prize winner.
With the "scattering" phenomenon, the following astronomical phenomena can be explained: for example, the sky above you is blue, but where the horizon meets the sky, the sky looks almost white. Why? This is because sunlight travels far in the air from the horizon to where you are than it falls directly from the air-and it naturally eats more particles along the way.
These large particles scatter light many times in this way, so it appears light blue in white. I suggest you do a small experiment to verify it: take a glass of water, put it in a dark background, put a drop of milk, and then illuminate one end of the cup with a flashlight and get close to it. The light of a flashlight will appear light blue in water.
If you put more milk into water, the water will be whiter, because the light is repeatedly scattered by many milk particles, and the result is white. It is as white as the horizon.
When the sun goes down in the evening, the sky turns red instead of blue, and the setting sun turns dark red. Due to the countless particles that the sunset glow encountered on the way to your place, the purple and blue parts of the sunlight scattered in all directions, leaving only a little orange-red light visible to the naked eye-because of their long wavelength and "big waves", they crossed the obstacles on the road.
However, if you are careful, you will find that the sky will be dark blue for some time after sunset. This used to be a strange thing that scientists cared about, but several physicists solved the mystery 50 years ago: the blue color that caused the dusk sky was a special substance.
This special substance gathers into a thick layer at a height of 20 to 30 kilometers from the earth's surface, which is called the ozone layer. This gas acts as a color filter for the falling sunlight: it intercepts the yellow and orange parts of the sunlight, but lets the blue part pass almost unimpeded.
When the last light disappears, all the colors disappear in the night. Ozone not only creates the blue sky at dusk, but also swallows a special kind of light that you can't see: ultraviolet light, or ultraviolet light.
You must have heard how dangerous ultraviolet rays are to all living things, including you. If it shines on your skin for too long, you will get sunburned.
The ozone layer everywhere is thick enough to intercept as much ultraviolet rays as possible: this is extremely important for all life on our planet. Unfortunately, today, this life-threatening protective layer has become thinner in many places, and even a big hole has been formed over the South Pole.
The killer of ozone destruction is "Freon"-an ozone that people use.
5. Why is the sky blue? Why don't fish sleep? ""Why are stones not afraid of pain? ""Where does the bird bathe? " "Why can't the grass talk? "... when I was a child, I was full of infinite curiosity about the world! But what I am most curious about is: Why is the sky blue? Put forward a series of questions, lead to the theme, and properly take care of readers' concerns.
I have also imagined why the sky is blue, because God knocked over the blue paint while painting. Is it because Grandpa Sun gave Brother Sky a blue coat? Or is it because the lake gives the sky a little blue light?
Romantic imagination, although there is no scientific explanation, increases the interest.
The sky we see is often blue, especially after a heavy rain. The sky is as blue as autumn water, which makes people feel relaxed and eager to fly. In order to understand this long-buried mystery, I began to look it up on the Internet.
I didn't know until I saw it. It turns out that the atmosphere is colorless, and the blue of the sky is produced by atmospheric molecules, ice crystals, water droplets and other substances under the action of sunlight. When sunlight enters the atmosphere, long-wavelength colored light such as red light has strong penetrating power and can penetrate the atmosphere and shoot to the ground. However, when blue light with short wavelength comes into contact with atmospheric molecules, ice crystals, water droplets and other substances, it is easy to scatter. Scattered blue, purple and cyan light filled the sky, turning it into a piece of blue we saw.
6. The composition "The sky is still so blue" is no less than 600 words, with narrative and urgent need. I don't know when it became my hobby. When I have time, I can't help looking at the narrow sky. White clouds are floating in the blue sky, and cheerful birds are flying freely in the sky. The sky is so new, so beautiful, so blue, I also get a kind of it. But I cried that day. The examination papers were handed out, followed by piles of red crosses. The teacher talked to me again and came out of the office. I'm at a loss. Although I had a lot of homework, I didn't do it. I unconsciously walked aimlessly on the playground alone. "What should I do? What's going on here? What is the reason? How can I be worthy of my parents? " Unconsciously, the past came to mind. "I want to do math homework, read books and think about popsicles, and even exams are in my heart." Before, that heartbreaking scene. I cried out in pain and everyone passing by looked at me in amazement. I sighed. Suddenly found that today's sky is still so beautiful. Although it is a narrow sky, the blue is spotless. Looking at the rising sun and the setting sun, I thought of a famous saying, "The sun is new every day." Looking at the beautiful sky, I suddenly realized: "The sky is new every day." Whether it is sunny or stormy today, tomorrow is always new. Therefore, I should be new every day. Suddenly, my eyes lit up, and the doubts in my heart were thrown outside the cloud nine. I breathed a sigh of relief and strode back to the classroom.

8. Ask for the 600-word composition "The sky is still so blue" (the teacher asked me to extract it, not that I don't want to write) "I am still the original me, or I am not the original me. As always, I rode my bike on my way to school, fought with my classmates as always, and returned to that deserted home as always. What is missing, what is missing. " Shanshan closed her notebook and lay on the beach with such eyes. It's a cloud! The sky without clouds is so monotonous. Two years ago, Shanshan's mother lay in the ward and died in a white room, a white bed and white sheets. White ended her life. At that time, Shanshan hated white. The sky without white clouds is so fond of it, but she is a little lost. I don't know why. "Shanshan." The girl stopped her. "Why? Remember again.
"She didn't go on. The waves "snapped" on the beach, and the white waves passed easily like happiness. "I didn't expect anything, Frost. Let's go! "Two people were walking in the waves, and the sea beat their trouser legs wildly." Frost, what should I do? Dad said he would bring an aunt back today, saying she was a guest. Who doesn't know?
It's my stepmother. ""nothing, it's a big deal to live in my house. " "Shanshan, it's okay. It should be no problem. I will accompany you in the evening. " First frost hold shanshan's hand and said. She was silent all the way to the door, hesitated for a moment, lowered her head and sipped her mouth, and paced up and down the door. "Shanshan. "A sonorous voice cried," MuRongShan!
Huh? Dad! Ah.
Auntie. "SAN SAN looked at this woman, regardless of her age, looks like her mother. She is more beautiful than her mother. "Why? Hey, aren't you going in? ""oh! Oh! " Shanshan with first frost rushed into the room. She fell on the bed crying, astringent, some bitter tears soaked Shanshan's heart, soaked first frost's heart, bitter and painful. "Frost, what should I do? ""mom, mom, what should the daughter do? "What is even more unexpected is that this time Shanshan's father took this woman to decorate the new house and got married the next day. These made Shanshan almost cry herself out. The next day came and passed so fast that Shanshan forgot how she ate and walked. At night, the night sky is quiet, and one or two lonely stars are like a lonely heart. Those who lay quietly felt the chill of the wind. Thinking about how to go tomorrow.
"Shanshan heard the conversation and came to her father's door gently." How to face her tomorrow and take her to play? Where are you going? Well, I'll cook her the child's favorite food early tomorrow morning.
"The woman was excited and worried, for fear that Shanshan would get angry. Shanshan smiled, her eyes became energetic, and a faint smile floated around her mouth. The next day, the woman got up early and cooked a table of breakfast. Shanshan walked out the door with a smile. "mom! Good morning! ""ah! " The woman was surprised. She smiled. The sun is so high, the sky is still so blue, so transparent and so comfortable. White clouds appeared and the sky was more beautiful.
9. Blue sky 600 words. It is urgent. The sky outside is blue.
I don't know when I began to like watching the sky. Look at the deep blue of the sky, which dilutes the sadness of a large area. I am not a sad person, but words make people feel distressed.
You look at me for a while and at the clouds for a while. I think when you look at me, it's far away, and when you look at the clouds, it's close.
Gu Cheng's poems always have a touch of melancholy, so beautiful that people are worried. I copied the poem on the white homework paper and felt uncomfortable. When I looked out of the window, the color of the sky seemed a little dim, just like my eyes when I got the paper marked with red.
I tried to convince myself that it was just a so-called slip, just a fall from a very high cliff. But I know it's not the first time.
I decided not to tell my mother about my grades. I know she's busy. Her brother is going to college, and she can't let go anyway. I don't want to upset her.
The day they left was Saturday. Because of the class, some regrets are that I can't see Xiamen University. I laughed and said goodbye to them loudly. No one can see the loneliness in my heart I was the only one that day.
There was some noise when the phone called. Mom said it had arrived. I didn't answer, just listened to her quietly, and then tears fell down. I know she can't see it.
The sky is rare and pale, like a piece of rice paper, dripping with ink, waiting for the moment of rendering at night. It's really bad weather, I think, and my heart is inexplicably lost.
I began to doubt whether I was prone to schizophrenia and had the most pessimistic thoughts about many things. Life is like a net, covering me in endless shadows. I can't get rid of it, but I struggle in nightmares every day. I have been reluctant to admit my loneliness, and the bitterness of chewing is hidden in my surly smile. I just want to prove my strength. But at that moment, I felt unprecedented loneliness.
I don't know, is the world a little cold? ...
As a result, various symbols were scrawled on the paper. I want to keep a lot of diaries and then sleep in words. I don't want to make myself feel bad all the time, and I don't want to soak my moldy mood in tears that are hard to dry up. I have made up my mind not to cry, but I know I don't have enough courage to let go, and I am doomed to get hurt. Is youth really painful?
I think the world would be much less sad without me. Occasionally, I will think of many things, those memories that are dusty in the depths of my memory. I can only take the past to warm my loneliness and get a moment of happiness. Copy happiness? Suddenly feel ridiculous. Maybe only in this way can I anesthetize my empty mind.
The telephone rang in a hurry, showing its agitation in the big room. Pick up the phone, the other end of the phone is still noisy. It's mom.
"... the sky outside is blue ..."
Looking out of the window, the sky is pure and almost transparent. Coloured clouds bloom in the sky, and blue spreads in it, as if a dream is constantly unfolding, making people forget everything, pain or sadness.
In an instant, I was in tears.
In a trance, I remembered that I had a terrible dream the night before I left. In my dream, I was helpless, like a boat, wandering in the rapids. It was my mother who held my hand tightly and freed me from the shock. She warmed my cold all night with those hands.
Putting down the receiver, I took a deep breath. Dry the tears in the corner of your eyes and let the memory dry the scars. I put myself in the scattered sunshine. I believe that no day is destined to be dark.
Because, the sky outside is very blue. ...
10. How to write blue sky composition The sky is blue, because the universe is blue; The sea is blue, because the sky is blue; My desk lamp is blue because my heart is blue.
When buying a pencil case, blue is the first choice; When choosing a pen, the proportion of blue is indispensable; Blue is blind when buying clothes. I seem to want to create a blue sky of my own.
Blue represents youth, and hope is always full of vitality; Blue represents happiness, and I hope to be ordinary and happy all my life. In my eyes, in my heart, blue represents all beautiful things.
Perhaps, what I yearn for is not only blue, but the blue, vast and boundless sky! I want to turn into a wild goose and fly to the long-awaited sky; I would like to be a bird, flying freely in the song of the wind and against the background of white clouds! Yes, what really makes me yearn for is the beautiful blue sky!
