Observe a natural phenomenon, such as sunrise, full moon and lack of moon, spring breeze and spring rain, fog and fog. Write down its changing characteristics and choose your own topic.

The horizon has revealed the dawn of pink, and the color has gradually deepened, from orange to light red, and the light red has gradually deepened. Sometimes it is red, sometimes it is gold, sometimes it is purple, sometimes it is yellow, and some colors are really colorful. The shape of the morning glow changes endlessly, some are like eagles spreading their wings, and some are flying in the air like red scarves.

sunset glow

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

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

Sunset is like a painter adjusting colors in a palette. When he adjusted them, the most beautiful scene in the sunset appeared before our eyes. There is a "raging fire" in the endless western sky. At this time, the fire brigade arrived and they put out the fire immediately. When the sun goes down, the fire becomes smaller and smaller.

When the sun completely falls into the western hills, the fiery sunset also puts away the last ray of light with people's laughter.

spring breeze

People always appreciate the joy that spring brings to the world, but they just boast that spring is good and wonderful, but they don't know that it is actually the spring breeze that restores vitality and vitality to everything. Spring breeze can travel freely in every corner of the world without restriction, bringing endless vitality and immortal laughter to that corner. Spring breeze has no name. But ..... When the spring breeze drifted over the treetops, it inadvertently disturbed the sleeping old tree, and the old tree began to sprout; But when it was playing casually and flying over the grass, it accidentally touched the grass, so the grass began to greet it warmly; The spring breeze cheered up and began to consciously wake up the flowers, trees, fish, insects, birds and animals that were almost unconscious in the long winter. Since then, it has this nice name-Spring Breeze. Although the spring breeze awakens the jasmine in spring, it doesn't care that others are the messengers of spring. Let it go, because the jasmine in spring is the best friend of the spring breeze, and the spring breeze is always the first to awaken it. Therefore, the winter jasmine blooms first and shows people the vitality brought by the spring breeze. At this time, people always can't guess who woke up the flower, and everyone kept praising how beautiful the beige winter jasmine is. Whenever Chunfeng sees people praising its good friends, it always smiles with relief and goes to other places to "do good deeds". Spring breeze, it is soft and warm. It is not like the sultry cool wind in summer, the cold autumn wind in autumn and the biting cold wind in winter. Spring breeze, just spring breeze, has its own characteristics that others don't have. Spring breeze is selfless, it serves everything in obscurity; Spring breeze is modest, others praise it, compatriots praise it, it always smiles and says it is not good, and then goes to work enthusiastically; Spring breeze is beautiful, it has its own unique temperament, unlike cool breeze, which always makes people feel uncomfortable, unlike autumn wind, heartless, and even less like cold wind, which bullies others. It always considers others and mixes the most comfortable colors and temperatures. Isn't the spring breeze a close-up of our great people's teacher? It is as obscure as a teacher, enthusiastic and selfless. Teachers always think of our students, tailor their study plans for us, and even wish to pour knowledge directly into our heads. They don't want us to be useful people to build our motherland as soon as possible! Silkworms in spring will weave until they die, and candles will drain the wick every night. This famous sentence, which has been told through the ages, describes our great people's teacher? I think so, because this sentence is used on teachers, and they deserve it. What a great thing it is that they devote their lives to training us stubborn students. From the moment they make up their minds to be teachers, they can only hold us students in their hearts. Teacher, this is a sacred title. Being a teacher is an arduous task. It carries the future of the motherland and the hope of the nation. Only with enough courage and strength can we bear this burden. Spring breeze-teachers, what a bright proportion, what a great spring breeze, it accompanies teachers, repeating their simple and happy tasks year after year.

spring rain

It just rained a few times in Mao Mao. This spring rain, like an envoy sent by Miss Chun, came to the world with spring in the new year.

Spring rain began to fall in the wheat field, and the green wheat seedlings rubbed their relaxed eyes after a winter break, revealing their little green heads. In the light breeze and drizzle, the wheat seedlings stretched their short bodies heartily and enjoyed the first gift given to them by teacher Chun-the spring rain.

Spring rain falls on the pond, and the ice in the pond has melted. Fish are turning freely in the pond. They swim to the surface one by one, jumping and enjoying the bath of spring rain. The frog in the pond, after a winter, jumped ashore from the water and let the spring rain fall on him. They jumped from shore to water for a while, and then jumped from water to shore. He shouted happily from time to time: "Goo goo, goo goo, goo goo". The spring rain has added a lot of vitality to the pond.

The spring rain falls in the Woods. After a winter, the forest is full of yellow mud and the trees are bare. After a spring, it looks like a stain. The Woods seem to have taken off their winter clothes and put on the spring clothes that Miss Chun made for them. The spring rain added a bit of "green" to the forest.

Spring rain falls on the lawn. The grass changed from yellow to green after a spring rain. Green is fresh, green is lovely and looks full of vitality. On the edge of willow trees, thousands of willow trees with yellow leaves are also spread out and floating in the wind. Spring rains bring infinite vitality to grasslands and willows.

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

Spring rain! I love you!

The fog cleared.

It has been foggy in this city for a week. The weather forecast has always said that fog reduced the visibility of the air and the plane took off on time. The fog suddenly increased the number of sick people, and the hospital was crowded.

Riding on the road in the morning, endless fog is like a nightmare. The people in it, as if they were no longer real, drifted into an infinite void. The air is stagnant, and it feels slightly spicy when inhaled into the lungs. Most passers-by wear masks, and only a pair of eyes are exposed, which increases the ambiguity in the fog. Looking back and forth, I can't see the figure five meters away. People walk through the fog, surrounded by chaos, looking up at the tree, a thin layer of fog hanging, furry, like a pair of lazy sleeping eyes. From time to time, cyclists hurried by from behind, and the hurried back was as vague as ghosts in an instant. The person in it is like being held in a warm arms, because the eyes can't see clearly, because the light can't pass, and the vision is hazy. Under the cover of fog, people can imagine freely and act spontaneously. People are in fog, and fog is in dreams. At that time, they did not know the truth.

Crossing the road, the thrilling and roaring vehicles on weekdays are hidden in the white fog and slowly move forward. Faded the sharp and true side, generous and peaceful, no longer sharp-edged. Far away, I only saw the lights on, vaguely, like lanterns hit by snow in festivals, and they were no longer on. Everything is in the fog, if nothing happens, it will be easy. Riding a bicycle diagonally across the street, I was a little distracted for a while and slowed down unconsciously. The headlights in front of me suddenly turned on, and I found myself almost tangent to the vehicle. I couldn't help but break out in a cold sweat and people woke up from my dream. Look at the dense fog, which is still spreading slowly. It was foggy in the morning behind me, and it was a blur five meters away.

The fog is still heavy ahead, and the fog has no intention of stopping. I always thought that after a few steps, the ambiguity would eventually become clear. Approaching hopefully, clear steps become a new starting point, the road extends under your feet, and the front is still empty and foggy. Everything in the fog is like a confusing game, tempting you to stop moving forward, get out of one fog and enter another.

My mind suddenly welled up in Xi Murong's poem:

When the fog rises,

I am in your arms.

The forest is full of moist fragrance.

Full of things that are constantly being copied.

teen

By the time the fog clears, it will be a lifetime.

The mountain is empty and the lake is still.

This is all that's left.

Of thousands of people,

Never go wrong.

Someone's back

The mountains and lakes are quiet and the back is clear. Walking on the road, I got lost in the fog. ...

Spring Rain Spring has arrived, and Miss Chun has come with her child-Spring Rain. When I first arrived at Mother Earth-Grandma, the naughty spring rain kept busy. He looked around and ran around, making grandma frozen by the humidity of winter, making her as gentle, soft and fragrant as before. Because of the spring rain, trees and seedlings on the earth began to grow. They should blend with the breath of spring and be full of vitality, and decorate Mother Earth with their own different colors. "Wow, how beautiful grandma is!" Spring rain looked at all these changes and jumped up happily. Happy spring rain is singing, grasping the leaves and swaying, jumping in the lattice composed of veins, sliding from one leaf to another ... Suddenly, he saw that Mother Earth was still frowning, and asked inexplicably, "Grandma, why are you unhappy?" Earth Jupiter said, "Good boy, look, isn't there a bare place on the surface of my stratum?" This is the grass doll sleeping late and refusing to get up! After listening to Chunyu's words, she said, "Don't worry, Grandma, I will find him." "Then he plunged into the mud. After finding the grass doll, Chunyu asked him. "It's spring now, why don't you go out? ""... "The grass doll stretched herself and said," I still have to sleep. I am sleepy. " "You can't sleep. In this way, you will never see the sun in the soil. After a long time, even the roots will die. Everyone is waiting for you! " "What you said is true? All right, I'll go to the ground right away. "Since then, the grass doll has gathered all its strength, grown up hard and sprouted slowly." Let me help you! "The spring rain sends out strength and moistens the grass dolls. Finally, the grass dolls came out of the soil and dyed the bare ground green, so Mother Earth became more beautiful. From then on, the grass doll and Chunyu became good friends. Every spring, as soon as the spring rain comes to Mother Earth, the grass dolls no longer stay underground to sleep late, but quickly emerge from the ground and sing Haruka with everyone. This is the story of the spring rain.

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

Spring rain falls like a wisp on the field, nourishing the green wheat seedlings. The spring rain awakens the sleeping earth, and the grass wakes up to suck the sweet milk.

The spring rain is falling, the rain is foggy, and thousands of silver wires are rippling in mid-air, just like a bead curtain, covering everything like a cloud.

The spring rain falls on the willow leaves, "rustling sand", like a girl stroking the strings gently, and like a silkworm baby swallowing mulberry leaves.

The spring rain is falling, and the raindrops fall on the pink petals of peach blossoms, rolling like colorful pearls. Thin rain, like the thread spun by a spring girl, falls in a "rustling sand".

Look, the gauze-like drizzle hangs over the earth like smoke, making it look picturesque. The pavilion on the top of the green glazed tile is shrouded in drizzle, like a layer of white smoke, like a jade building in the sky. Willow is surrounded by drizzle, swaying 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 light green grass covered by drizzle shook itself off the ground.

Spring rain, sprinkled on the river, a silver flower appeared on the calm water. The clever fish jumped up and made a splash, as if sucking the crystal rain.

Rain, seeping into the soil, wheat seedlings are spreading green buds, with sparkling rain and dew, willow trees are drunk, stretching their bodies and shaking their waists.

Spring rain is falling, you are the messenger of the spring girl, you come to the earth with spring, you give the earth a kind of vitality, moisten the green wheat seedlings, embrace the gurgling stream and radiate.

The fragrance of the earth ... ah, how beautiful! This water, this grass and this tree constitute a beautiful scenery that only spring rain can describe!

Spring rain is falling ... jargon ... the earth laughs.

When the moon is full, people always like to sit at the table, eat delicious food and enjoy the family warmth brought by family reunion. When the moon is short, most people are busy, for life and career. Why do people always miss home when the moon is full? That's because you will have a feeling of "full family reunion" in your heart. Perhaps this is the "state of mind", as monk Hui Chong said, "I think you look like the Buddha." It's not that you really look like a Buddha, but that people who look at people have a Buddha in their hearts, an open spirit and can accept all rivers. Every one of us who lives in society must accept many other kinds of people and things. It is even harder to learn to tolerate others. What's wrong with being alive? If you tolerate him, maybe one day, someone will tolerate you. There is a full moon in your heart, even if everything is flawed, you can see the imperfect beauty from it. Why can brokeback Venus be praised? Why do people think that Venus without arms is better than Venus with any form of arms? Because it was her broken arm that highlighted her fullness. Because she broke her arm, which makes people think and feel mysterious. This is the beauty of defects. This is because of the "full moon" in your mind, you feel that everything is beautiful and all mistakes can be forgiven, so incompleteness is also a kind of beauty, and even the beauty it embodies can surpass other complete objects.

People are always pursuing perfection, pursuing the perfection of everything. So "there is no best, only better" has become everyone's goal. Therefore, taking "perfection" to measure everything has become a convention. There was a girl who felt that she was not beautiful enough and "perfect" enough, and was willing to go to the hospital for large-scale plastic surgery, so she had the "first artificial beauty". But she is not ugly, but she is not outstanding enough, but she is still unwilling and feels that she is not "perfect" enough. The moon in my heart is missing. Even if I become a beauty, how can I feel it? Since you are so hard on yourself, you must be more harsh on others. Her nose is not high enough, her eyes are not big enough, he goes too far and speaks thoughtlessly ... everything is wrong, everything is wrong. If everyone has to haggle over every ounce, what fun is there in our life? Is it nitpicking? See others do wrong, gloat; I am filled with joy to see that others are worse than myself. Everyone has a broken moon in his heart, and everyone has malice in his heart. So how can life be peaceful? How can the world find peace?

Please plant a full moon in your heart and accept everything from others with a pure and generous heart. Whenever you say it, don't be too ugly. From another angle, the scenery will be better. There is no difference between a full moon and a lack of one.

Full moon and lack of moon

In the vast starry sky, the most striking celestial body will light up in a few months. Its ever-changing appearance and the beautiful myths and legends it carries from ancient times to the present have added a lot of poetry and painting to this world! In Guanghan Palace, there is a jade building in Qionglou, where Chang 'e dances. Not only that, the periodic ups and downs of the moon are also one of the bases for people to make calendars since ancient times.

The moon revolves around the earth and rotates at the same time. The two periods are the same and the direction is the same, so the moon always faces the earth on the same side. In the long years before the satellite went into the sky, people never saw the back of the moon.

Why does the moon change? As we all know, the moon itself does not shine, but only reflects part of the sunlight that shines on it. In this way, for observers on the earth, with the change of the relative positions of the sun, the moon and the earth, the moon presents different shapes on different dates, which is the periodic change of the moon phase. Furthermore, although the moon is always illuminated by the sun, and the half sphere is bright, because the moon is constantly revolving around the earth and changing its position, the half sphere facing the earth and the half sphere illuminated by the sun sometimes completely overlap, sometimes completely do not overlap, sometimes a small part overlaps, and sometimes most of them overlap, so the moon presents a cloudy or sunny change.

When the moon is between the sun and the earth, its dark hemisphere is facing us, and we can't see any images of the moon at all. This is the "new moon". In astronomy, the new moon refers to the moment when the yellow meridian of the moon is the same as the yellow meridian of the sun. On the first day of the new moon, the moon and the sun rise from the east at the same time. Even if the earth reflects sunlight to the moon, the part of the light reflected by the moon will be completely submerged in the strong sunlight.

When the earth is between the moon and the sun, although the three planets are also on the same line, at this time, the moon hemisphere illuminated by the sun is facing the earth, and the soft moonlight shines on the earth all night. This is the full moon, which is "looking". At this time, the difference between the lunar longitude and the solar longitude is 180 degrees.

Because the distance between the moon and the earth is too short compared with the distance between the sun and the earth, the speed of the moon moving eastward on the celestial sphere is much faster than that of the sun. The moon advances from west to east every day 13 degrees or more, while 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 goes down, a crescent moon can be seen in the western sky, with two sharp corners pointing to the east. From then on, the moon rose later and later, and it gradually became round. About seven days after the new moon, the yellow meridian of the moon just exceeds the sun by 90 degrees. The moon we see is a semicircle, and the arc faces west. This is the first quarter moon. After that, the moon continued to the east, more round, and then rose until it looked out. From the new moon to the moon, the distance between the moon and the sun is getting bigger and bigger.

Looking at the past, the moon gradually moved closer to the sun, and the surface of the moon gradually became thinner. When the yellow meridian of the moon exceeds the yellow meridian of the sun by 270 degrees, it becomes a semicircle again, but the arc faces east, which is the last quarter moon. At this time, the sun rises in the east and the moon is high in the southern sky. Naturally, the moon is invisible to our naked eyes. After the first quarter moon, the moon will not come out from the east until after midnight. Its semicircle is gradually eroded and becomes a narrow sickle with a sharp angle to the west. Looking at the new moon, the moon and the sun are getting closer and closer, and even disappear into the morning light like the ecliptic of the sun.

The cycle of the moon phase change, that is, the time from the new moon to the new moon or from the new moon to the new moon, is called the first month. The observation results show that the length of Wang Shuo's moon is not fixed, sometimes as long as 29 days 19 hours, sometimes only 29 days and 6 hours, and its average length is 29 days 12 hours, 44 minutes and 3 seconds.

The time interval between the moon and a star at the same time is called "sidereal moon", which is the real cycle of the moon's orbit around the earth. Wang Shuo's moon is longer than the star moon, just as the sun is longer than sidereal day. The moon and the stars have little to do with daily life, but it is the ebb and flow cycle of the moon, which is related to the ebb and flow of the earth, navigation and fishing, and has a great influence on people's activities at night. At the same time, it also occupies an important position in the last month of religion, so people naturally regard it as a longer time unit than a day.

sunset glow

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

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

Sunset is like a painter adjusting colors in a palette. When he adjusted them, the most beautiful scene in the sunset appeared before our eyes. There is a "raging fire" in the endless western sky. At this time, the fire brigade arrived and they put out the fire immediately. When the sun goes down, the fire becomes smaller and smaller.

When the sun completely falls into the western hills, the fiery sunset also puts away the last ray of light with people's laughter.

Colorful clouds sometimes appear on the horizon around sunrise and sunset. The chardonnay seen in the eastern sky around sunrise is called morning chardonnay, and the chardonnay around sunset is called sunset chardonnay.

Haze is the result of sunlight passing through the thick atmosphere around sunrise and sunset and being scattered by a large number of air molecules. When there are many impurities in the air, such as dust and water vapor, its color is more obvious. If there are clouds, they will also be dyed orange and red.

The bright red glow before and after sunrise shows that there is already a lot of water vapor in the atmosphere, and clouds have invaded this area from the west, indicating that the weather will turn to rain. The appearance of a bright red and golden sunset indicates that the weather in the upper reaches of our western region has cleared up or the clouds have split, and the sunlight can penetrate to cause the sunset glow, indicating that the rain clouds hanging over the local area are about to move eastward and the weather will clear up.
