Observe a natural phenomenon, such as morning glow, full moon and waning moon, spring breeze and spring rain, fog rising and dispersing, etc., and write down its changing characteristics. You can choose a title of your own.

Zhaoxia

A pink dawn has appeared on the horizon, and the color has gradually deepened, from orange to light red, and the light red gradually deepened, sometimes red, sometimes golden, After a while, it was half purple and half yellow, and there were some colors that I couldn't describe, and some colors that I had never seen before. It was really colorful. The shape of the morning glow is endless, some are like an eagle spreading its wings, and some are like a red scarf flying in the air.

Sunset

Some people like the stars in the sky, some like the bright moon, and some like the fireball-like sun. But I like the colorful sunset.

The sunset is picturesque and refreshing. Whenever I admire the sunset alone, the fairyland-like sunset can always make me forget the worries and fatigue of the day and put me in another world.

The sunset is like a painter adjusting colors on a palette. When he has finished adjusting, the most beautiful scene in the sunset appears before our eyes. A "raging fire" ignited in the endless western sky. At this time, the fire brigade arrived. They immediately put out the fire. As the sun went down, the fire became smaller and smaller.

When the sun completely sets behind the mountains in the west, the fiery sunset also puts away its last ray of light along with people's laughter.

Spring Breeze

People always appreciate the joy that spring brings to the world. They only praise the good and wonderful spring, but they don’t know that it restores vitality and vitality to all things in the world. The biggest contributor is actually the spring breeze. The spring breeze can travel to every corner of the world at will, without restrictions, and as it pleases, bringing endless vitality and immortal laughter to that corner. The spring breeze has no name. But... when the spring breeze drifted through the treetops, it accidentally disturbed the sleeping old tree, and the old tree began to grow small buds; and when it was playing casually and flying over the grass, it accidentally touched the grass. , so the grass began to greet it enthusiastically; the spring breeze became happy and began to deliberately wake up the flowers, plants, trees, fish, insects, birds and beasts that had almost lost consciousness in the long and harsh winter. Since then, it has had this nice name - Spring Breeze. Although the winter jasmine is also awakened by the spring breeze, the spring breeze does not care if others ask the jasmine to be the messenger of spring, because the jasmine is the best friend of the spring breeze, and the spring breeze will always wake it up first. Therefore, the winter jasmine is the first to bloom and show the vitality brought by the spring breeze to people. At this time, people always don't guess who awakened the flower. Everyone praises the beige color. How beautiful are the winter jasmine flowers. Whenever the spring breeze sees people praising its good friends, it will always smile happily and go to other places to "do good things". The spring breeze is soft and warm. It is not like the sultry cool wind in summer, nor the cold wind in autumn, nor the biting cold wind in winter. Spring breeze is just spring breeze. It has its own characteristics that others do not have. The spring breeze is selfless, it serves all things in obscurity; the spring breeze is humble, others praise it, and its compatriots praise it. It always smiles and says that it is not good, and then goes back to work enthusiastically; the spring breeze is beautiful, and it has its own unique temperament , It is not like the cool wind that always makes people feel uncomfortable, it is not like the autumn wind that is cold and ruthless, and it is not as bully as the cold wind. It always considers others and creates the most comfortable colors and temperatures. Isn't the spring breeze a close-up of our great people's teachers? It is as unknown as a teacher, enthusiastic and selfless. Teachers always think about us students, tailor-made learning plans for us, and even want to pour knowledge directly into our heads. Don’t they want us to become talented as soon as possible so that we can build our motherland? The spring silkworm's silk will not be used up until it dies, and the wax torch will not dry until it turns to ashes. "Is this famous sentence that has been passed down through the ages describing our great people's teachers? I think so, because this sentence is applied to teachers, and they deserve it. They have dedicated their lives to cultivating stubborn students like us. , how great this is. From the moment they make up their mind to be teachers, they can only hold us students in their hearts. Teacher, this is a sacred title, and being a teacher is an arduous task. Carrying the future of the motherland and the hope of the nation, only those with enough courage and strength can shoulder this heavy burden. The spring breeze - teachers, what a vivid proportion, what a great spring breeze, it accompanies teachers through the year. Another year, repeating my simple and happy task

Spring Rain

This spring rain has just fallen, like a messenger sent by the spring girl. , in the New Year, came to the world with spring

The spring rain fell on the wheat fields. After a winter of rest, the green wheat seedlings rubbed away their loose sleep, revealing the green little ones. Head. The wheat seedlings stretched their short bodies in the breeze and drizzle, enjoying the first gift given to them by the spring girl.

The spring rain fell on the pond. The ice in the pond has melted, and the fish are turning their bodies freely in the pond. They swim to the surface one after another, jumping, enjoying the bath of spring rain. After a winter, the frogs in the pond have emerged from the water. Jumping up to the shore, they let the spring rain rain on their bodies. They jumped from the shore into the water, and then jumped from the water to the shore.

From time to time, they would shout happily: "Guergua, Guergua". The spring rain adds a lot of vitality to the pond.

The spring rain fell in the woods. After a winter, the woods were filled with yellow soil and the trees were bare. After a spring, it is like a dye. The woods seem to have taken off their winter clothes and put on spring clothes made for them by the spring girl. The spring rain adds a bit of "green" to the woods.

The spring rain fell on the lawn. After a spring rain, the grass turned from yellow to green. The green is fresh, lovely, and full of vitality. The willows on the side also unfolded thousands of willow threads with yellow leaves, floating in the wind. The spring rain brings infinite vitality to the grassland and the willow trees.

Ah! Chunyu, you are the messenger sent by Miss Chun, bringing infinite vitality to our earth! Spring Rain, you are the prelude to the hymn of spring, and you have dedicated all your strength to the earth.

Spring rain! I love you!

The fog rises and the fog clears (together)

The city has been covered in fog for a week. Weather forecasts have been saying that fog reduces air visibility, making it impossible for planes to take off on time; fog makes the number of sick people suddenly increase, and hospitals are overcrowded.

Cycling on the road in the early morning, the endless fog filled the air like a nightmare. In it, people seem to be no longer real, and fall into the infinite void in a confused way. The air is stagnant, and when inhaled into the lungs, there is a slightly spicy feeling. Most of the pedestrians passing by wore masks, with only one pair of eyes exposed, which further increased the sense of ambiguity in the fog. Looking back and forth, I couldn't see a figure five meters away. People are walking through the fog, surrounded by chaos. When they look up at the trees, they are covered with a thin layer of fog, which is as fluffy as a pair of lazy sleepy eyes. From time to time, a cyclist rushes past, his hurried back like a ghost, blurry in the blink of an eye. People in it feel as if they are being held in a warm embrace. Because the eyes cannot see clearly, because light cannot pass through, the vision is hazy. With the cover of fog, one can freely imagine and act as he pleases. People are in the fog, and the fog is in their dreams. For a moment, they are at a loss to tell the truth from the false.

Crossing the road, the usually thrilling and roaring vehicles were hidden in the white fog and moved forward slowly. The sharp and real side has faded away, becoming generous and gentle, no longer sharp-edged. In the distance, I could only see the car lights on, dimly, like lanterns that were beaten by snow during the festival and were no longer bright. Everything is sinking in the mist, as if there is nothing, neither speed nor slowness. I was riding a bicycle diagonally across the street. I was a little distracted for a moment and slowed down unknowingly. When the car lights suddenly brightened in front of his eyes, he realized that he and the vehicle were almost passing by each other. He couldn't help but break into a cold sweat and woke up from his dream. Look at the thick fog, which is still spreading slowly. The morning fog is hazy in front of and behind you, and there is a blur five meters away.

The front is still hazy, and the fog shows no signs of stopping. I always think that after taking a few steps, the blur will eventually become clear. Approaching with full hope, a few clear steps become a new starting point, the road stretches out under your feet, the front is still empty and misty, everything in the fog is like a confusing game, tempting you to step forward and walk out of the fog. , entering another fog.

Xi Murong's poem suddenly came to my mind:

When the fog rises

I am in your arms

In this forest Full of moist fragrance

Full of the time that keeps reappearing

Youth time

After the fog cleared, it was a lifetime

The mountains are empty and the lake is quiet

Only that remains

among thousands of people

there is no mistaking it

Back view

The mountains are empty and the lake is quiet, and the back view is clear. I was lost in the fog while walking on the road...

Chun Yu Spring is here, and Miss Chun is here, and she also brings her child - Chun Yu. As soon as he came to Mother Earth, Grandma, the naughty Chunyu became busy all the time. He looked around and ran around, getting Grandma, who was frozen into the frozen soil by the harsh winter, wet and making her become like she used to be. Just as gentle and soft, exuding bursts of fragrance. The trees and seedlings on the earth have all begun to grow due to the moisture of the spring rain. They echo the breath of spring, are full of vitality, and decorate Mother Earth with their different colors. "Wow, grandma is so beautiful!" Chun Yu looked at all these changes and jumped up happily. The happy spring rain sang songs, holding on to the leaves to swing, dancing in the grid woven by the leaf veins, and slipping from one leaf to that leaf... Suddenly, he saw that Mother Earth was still wrinkled. With this brow, he asked in confusion: "Grandma, why aren't you happy?" Earth Jupiter said: "Good boy, look, aren't there still bare places on the surface of my strata? This is the straw doll You're sleeping in and won't get up!" After hearing this, Chunyu said, "Oh, that's it. Don't worry, grandma, I'll go find him right away." After that, he dove into the mud. Chun Yu quickly asked Cao Wawa after finding him. "It's spring now, why haven't you come out yet?" "..." Cao Wawa stretched out and said, "I still want to sleep, I'm sleepy." "You can't sleep. You will stay there forever. If you can't see the sun in the soil, even the roots will die over time. Everyone is waiting for you above!" "Is what you said true? Well, I will get down to the ground right away." The grass doll worked hard and grew upwards, and sprouts slowly appeared. "Let me help you!" The spring rain sent out its power again, nourishing the grass doll.

Finally, the grass doll emerged from the soil and dyed all the bare ground green, so Mother Earth became more beautiful. From then on, Cao Wawa and Chun Yu became good friends. Every spring, as soon as the spring rain comes to Mother Earth, the grass doll will no longer stay underground and sleep in, but will quickly emerge from the ground and sing the song of spring with everyone. This is the story of Chunyu.

Spring rain is the melody of nature and the messenger of spring!

The spring rain is pattering, falling like threads on the fields, nourishing the tender green wheat seedlings, the spring rain is pattering, Awakening the sleeping earth, the grass woke up and sucked the sweet milk.

The spring rain is falling, the rain and mist are filled, and thousands of silver threads are rippling in the mid-air, just like a bead curtain, covering everything like smoke and clouds.

The continuous spring rain sprinkles on the leaves of the willow trees, "rustling", like a girl gently stroking the strings, and like silkworms devouring mulberry leaves.

In the spring rain, small raindrops fell on the pink petals of the peach blossom, rolling like pearls shining with colorful brilliance. The thin raindrops are like the thread spun by the spring girl, falling "rustling".

Look, the gauze-like drizzle covers the earth like smoke, making the earth present a picturesque scene. The pavilion with green glazed tile roof was shrouded in drizzle, like layers of white smoke, just like a jade building in the sky. The willow trees were surrounded by drizzle and swayed gently in the breeze, like a group of fairies in gauze skirts singing and dancing for the arrival of spring. Not to be outdone, the tender green grass shrouded in drizzle trembled out of the ground to welcome the spring rain after the harsh winter.

The spring rain sprinkled on the river, and a small silver flower appeared on the calm water. The clever fish jumped and stirred up waves, as if they wanted to suck the crystal raindrops.

The rain seeped into the soil, and the wheat seedlings stretched out their green buds, facing the shining rain and dew. The willow trees were drunk, stretching their bodies and swaying their waists.

The spring rain is pouring, you are the messenger of the spring girl, you come to the earth with spring, you give the earth a vitality, nourish the green wheat seedlings, embrace the gurgling streams, and exude

The aroma of earth...ah, how beautiful! This water, this grass, and this tree constitute a gorgeous scenery that only spring rain can depict!

The spring rain is pouring... it is pouring... the earth is smiling.

When the moon is full, people always like to sit at the table, eat delicious food, and enjoy the warmth of family affection brought by family reunions. When the moon is waning, most people are busy with life and career. Why do people always miss home when the moon is full? That's because you will have the feeling of "full moon - round people - family reunion" in your heart. Maybe this is the "state of mind", like monk Huichong said: "I think you look like Buddha." It does not mean that you really look like Buddha, but that people who look at people have Buddha in their hearts, have a magnanimous spirit, and can embrace all rivers. Each of us living in society has to accept many other kinds of people and things. Learning to tolerate others is even more difficult. Who can live without faults in this world? If you are tolerant to him, maybe one day someone will be tolerant to you. There is a full moon in your heart. Even if everything has flaws, you can see the beauty in the flaws. Why is Venus de Milo so admirable? Why do people think that Venus without arms is more outstanding than Venus with arms of any kind? Because it is her incomplete arms that highlight her gracefulness. Because it is her incomplete arms that make people think about it and make them feel mysterious. This is the beauty of imperfection. This is because of the "full moon" in your heart, you feel that everything is beautiful and all mistakes can be forgiven, so incompleteness is also a kind of beauty, and the beauty it embodies can even exceed other complete items.

People are always pursuing perfection and perfection in everything. So "there is no best, only better" has become everyone's goal. Ever since, it has become a convention to use "perfection" to measure everything. There was a girl who felt that she was not beautiful enough or "perfect" enough, so she was willing to go to the hospital for major plastic surgery, so she got the "number one artificial beauty". But it was clear that she was not ugly, just not outstanding enough, but she still refused to accept it and felt that she was not "perfect" enough. The moon in my heart is missing. Even if I become a beautiful woman, how can I feel it? Since you are so harsh on yourself, you must be even more harsh on others. Her nose is not high enough, her eyes are not big enough, he does things too much, he speaks without thinking... There are faults everywhere, and there are mistakes everywhere. If everyone has to worry about everything, then where is the fun in our lives? Is it all about finding fault? When you see what others have done wrong, you gloat about it; when you see how others are worse than you, you are filled with joy. There is a incomplete moon in everyone's heart, and there is malice in everyone's heart. So how can life be peaceful? How can the world find peace?

Please plant a full moon in your heart, accept everything from others with a pure and magnanimous heart, and don’t rush to say bad things at any time. Change the angle and the scenery will be better. There is actually no difference between a full moon and a waning moon.

The full moon and the waning moon

The most eye-catching celestial body in the vast starry sky is the moon. With its ever-changing appearance, it has carried so many things from ancient times to the present. The beautiful and touching myths and legends add so much poetry and picturesqueness to the world! In the palace of Guanghan, Fairy Chang'e dances gracefully. Not only that, the periodic waxing and waning of the moon has also been one of the basis for people to formulate calendars since ancient times.

The moon revolves around the earth and rotates at the same time. The two have the same period and the same direction, so the moon always faces the earth with the same side. In the long years before artificial satellites were launched into the sky, people never I've seen the back of the moon's head.

Why does the moon wax and wane? As we all know, the moon itself does not emit light, but only reflects part of the sunlight that shines on it. In this way, for observers on the earth, as the relative positions of the sun, moon, and earth change, the moon changes on different dates. Showing different shapes, this is the cyclical change of the moon phases. Furthermore, although half of the spherical surface of the moon is always bright when it is illuminated by the sun, because the moon is constantly revolving around the earth and changing its position from time to time, the half of the spherical surface that is facing the earth is opposite to the half of the spherical surface that is illuminated by the sun. Sometimes the illuminated half-spheres completely overlap, sometimes they don't overlap at all, sometimes a small part overlaps, and sometimes a large part overlaps, so that the moon shows changes in cloudiness, sunshine, waxing and waning.

When the moon is between the sun and the earth, its dark hemisphere faces us, and we cannot see any image of the moon at all. This is "Suo", which in astronomy refers to the yellow phase of the moon. The same time as the solar longitude. On New Year's Day, the moon and the sun rise from the east at the same time. Even if the earth reflects the sun's light to the moon, and then the part of the light reflected back by the moon, it is completely submerged in the strong brilliance of the sun.

When the earth is between the moon and the sun, although the three planets are also in a line, at this time, the hemisphere of the moon illuminated by the sun is facing the earth, and the soft moonlight shines on the earth all night long. On the ground, this is the full moon, which is "looking". At this time, the ecliptic longitude of the moon and the ecliptic longitude of the sun differ by 180 degrees.

Because the distance between the moon and the earth is too short compared to the distance between the sun and the earth, on the celestial sphere, the moon moves eastward much faster than the sun. The moon advances a little more than 13 degrees from west to east every day. But the sun only advances 1 degree. Therefore, after the new moon, the moon quickly ran to the east of the sun. A day or two later, as soon as the sun set, a crescent moon could be seen in the western sky with its two sharp corners pointing east. After that, the moon rose later and later, and the moon gradually became fuller. About seven days after the first moon, the moon's ecliptic longitude is just 90 degrees beyond the sun. The moon we see is a semicircle with an arc facing west. This is the first quarter moon. After that, the moon continued to face the east, became fuller, and rose later, until Wangwang. From New Year's Eve to New Year's Eve, the moon's distance from the sun becomes larger and larger.

After looking over, the moon gradually moved closer to the sun, and the moon gradually became thinner. When the moon's celestial longitude exceeds the sun's celestial longitude by 270 degrees, it becomes a semicircle again, but the arc faces east. This is the waning moon. At this time, when the sun rises from the east, the moon is hanging high in the sky due south. Naturally, our naked eyes cannot see the moon at this time. After the last quarter, the moon does not emerge from the east until late at night, and half of its circular surface gradually erodes away, becoming a narrow sickle shape with the sharp corner facing the west. From the first day of the lunar month to the end of the lunar month, the moon and the sun are getting closer and closer, until they are once again the same as the sun's celestial longitude and disappear in the morning light.

The cycle of moon phase changes, that is, the time from new moon to new moon or from moon to new moon, is called synodic moon. Observation results show that the length of the synodic moon is not fixed. Sometimes it is as long as 29 days and 19 hours, and sometimes it is only 29 days and 6 hours. Its average length is 29 days, 12 hours, 44 minutes and 3 seconds.

The time interval between the moon and a certain star at the same time is called the "sidereal month". The sidereal month is the true period of the moon's movement around the earth. The synodic month is longer than the sidereal month, for the same reason that the solar day is longer than the sidereal day. The sidereal month has little to do with daily life, but the synodic month, because it is the cycle of the moon's waxing and waning, is related to the rising and falling tides of the earth, is closely related to navigation and fishing, and has a great impact on people's nighttime activities. The moon phases also play an important role in religion, so people naturally use the synodic moon as a longer unit of time than the day.

Sunset

Some people like the stars in the sky, some like the bright moon, and some like the sun like a fireball. But I like the colorful sunset.

The sunset is picturesque and refreshing. Whenever I admire the sunset alone, the fairyland-like sunset can always make me forget the worries and fatigue of the day and put me in another world.

The sunset is like a painter adjusting colors on a palette. When he has finished adjusting, the most beautiful scene in the sunset appears before our eyes. A "raging fire" ignited in the endless western sky. At this time, the fire brigade arrived. They immediately put out the fire. As the sun went down, the fire became smaller and smaller.

When the sun completely sets behind the mountains in the west, the fiery sunset also puts away its last ray of light with people's laughter.

On the horizon before and after sunrise and sunset, colorful clouds sometimes appear. The clouds seen in the eastern sky before and after sunrise are called morning glow, and the clouds before and after sunset are called sunset glow.

Clouds are caused by sunlight passing through the thick atmosphere and being scattered by a large number of air molecules around sunrise and sunset. When there are more impurities such as dust and water vapor in the air, the color becomes more pronounced. If there are clouds, the clouds will also be dyed in bright orange-red colors.

The bright red alpenglow appears before and after sunrise, indicating that there is a lot of water vapor in the atmosphere, and clouds have begun to invade the area from the west, indicating that the weather is about to turn rainy.

The appearance of bright red and golden sunset glow means that the weather has cleared up or the clouds have broken up in the upper reaches of our west, allowing sunlight to pass through to create the sunset glow. It indicates that the rain clouds hanging over the local area are about to move eastward, and the weather is about to clear up< /p>
