A work describing the changes of natural scenery

The sun pecked through the eggshell of the night, poked its head out and looked shyly at the earth.

At this time, far ahead, countless mountains and misty clouds suddenly appeared a piece of red mist.

Soon, Ran Ran in the ocean jumped out of a red ball, and the place where the water meets the sky suddenly turned into a raging fire. The sun finally poked out half of its head, so big and red, and then it seemed to be pushed and suddenly jumped out and turned into pure gold.

The sun suddenly jumped out of the sea, and in an instant, the vast sky and sea were covered with dazzling golden light.

The sky is getting brighter, and a purplish sunrise leaps from the back of Dongshan Mountain. Suddenly, the heavens and the earth were bright and the water overflowed.

Everything on the earth is as hot as gold. On the surface of the original color, it is heavily stained with a touch of orange, reflecting the dazzling brilliance of the road.

Gradually, the fog in the east was reddish at first, and then with the accumulation of red, a bright red line was suddenly drawn, and a red light wheel suddenly jumped out of the bright red.

The delicate and charming morning sun has jumped out from the back of the mountain in the east, overflowing with red clouds, blending with the slowly rising morning fog in the valley and changing the colorful aura.

The stars have faded and the eastern sky has turned white. At this time, the sky changed quickly, and gradually became dazzling, and then red lines began to radiate on the horizon.

The sun jumped out of the gray sea, and a small purple flame immediately lit up the dark sky. Behind the bright sunrise, it looks like an endless blue satin.

I see light blue against the blue sky. After a while, the light blue turned to orange with a crimson edge. This red light is more and more, shooting from the air to the sea, first a little, then a piece, and spreading rapidly in all directions.

In the composition describing the change of natural scenery, Baieling bus took us across the winding Panshan Highway to Yungu Temple in the back hill. There is a cableway from here to Baieling, but we finally chose to walk.

With young people's heroism and a desire to conquer, we walked the fifteen-mile mountain road with our feet, which is quite groundbreaking work for us.

It is said to be a mountain road, and people have already participated.

Routing steps are paved, winding, ascending, turning left and right, turning around and disappearing, but once you turn around, it is an endless road.

This reminds me of the way of life, doesn't it? It's just more complicated and tortuous, and it's much harder to walk. There may be many dead ends.

I don't know if I will succeed, but I believe I have the courage to go on.

The so-called walking without looking at the scenery, watching the scenery does not walk, people will be tired if they walk too much, so they will stop to look at the scenery from time to time and enjoy the strange peaks, strange rocks and clear water and strange trees that this paradise on earth has given us.

Huangshan skillfully matched the 3rd16th peak with the 36th peak, each with its own name and beautiful story.

Mountains and valleys, secluded pools and Tianzhu, set off the majesty of mountains and the delicacy of water.

Every stone in Huangshan also has a name, an allusion, a fairy leading the way, a magpie climbing plum blossoms, a dog looking at the sun, a dream pen giving birth to flowers, and a monkey looking at the sea, which is full of mystery and fairy spirit.

Huangshan has many peaks, rocks and water.

Up and down the sea of clouds, thirty-six sources, twenty-four streams, sixteen springs, eight pools and four waterfalls.

Qingquan waterfall flows down from the mountain, forming large and small pools, and the water is clear and biting.

The sound of water has always accompanied us to Baieling. Often we only hear the sound of water but can't see it. Through the thick leaves, we can vaguely see a silver belt from top to bottom. As soon as the road turns, clear springs and streams appear in front of us.

Along the way, I occasionally look up at the sky, and there is a fog around the top of the mountain. At that time, I felt that the whole person rose from the shell, reached the horizon and reached the cloud.

The ropeway only takes eight minutes. We walked for three hours and took a nap on the porch. We can't tell whether we are tired or tired, excited or excited. Some of us feel comfortable and proud. Just like the road of life, it is not easy to walk, but you have to walk after all, as long as you strut.

After picking up Cui and resting for half an hour on the road, we started our journey again.

There is a famous pine tree-Lianlisong on Shixin Peak in Huangshan Mountain. A pine tree grows into two trees, also called lovers pine.

It is said that all lovers and lovers will make wishes there, hoping to love each other forever.

I thought of awei in front of the tree and wanted to make a wish with him. Unfortunately, he left me a month ago.

From the day he left, I began to give up on him, and making a wish has long since become meaningless.

I smiled and walked away with a little heartache.

The North Sea descends from Xinxin Peak.

We rented two military coats and a sleeping bag here, and hurried to Paiyun Pavilion in the West Sea to watch the sunset.

The scenery in Paiyun Pavilion is beautiful, the sky is blue, reflecting the afterglow of the sunset with a little gray shadow; Mountain, the stone surface washed by thousands of years of running water is smooth and can be learned, and the peak is steep and straight into the sky; Trees, standing in the gap of the cliff, still have to be tall and straight, still have to go up, don't bend, don't bow their heads, and have to make various postures, with thousands of customs and tenderness.

Standing on the edge of the cliff, I have the urge to jump.

The wind was very strong, and I sat in Paiyun Pavilion, watching the sunset glow gradually redden the horizon and gradually put away her color.

When the last sunset swayed, I thought of awei again. He once said he would take me to see the sea.

I thought Huangshan would make me forget him, but hearing the familiar Cantonese and seeing the tour groups in Guangdong would remind me of him.

In fact, he is so ordinary. Maybe a few years later, when I think back on the road we have traveled, I will laugh at my confusion about this relationship, my naivety and infatuation today, and my wounds that have not healed so far.

After watching the sunset, with a feeling of depression, I returned to Beihai without saying a word.

I am not very happy. Han Shi takes care of me, but most of the time I still can't go out by myself.

Spread out seven sleeping bags, spread out coats, put on jeans and sweaters, divide ham and sausage among seven people, and chat with them.

Fatigue has long since disappeared, leaving only the heroism of calling myself "Seven Chivalrous Men of Huangshan Mountain" and my occasional frustration.

Sleeping in the hall, the mountain spring flows outside the house.

Woke up in the middle of the night, always thinking it was raining. When you go out, you will see the bright moon in the sky, the pines and waves, and the weather is fine.

Sunrise in Huangshan All the mountains have a big landscape-sunrise.

It was rainy those days, but the weather was exceptionally good.

There is no rain, and the sun is not vicious. Fortunately, we saw the sunrise that day.

At four o'clock in the morning, everyone sat on the flat stone next to Shuguang Pavilion, waiting for the sunrise.

The surrounding sky was gradually dyed red by the morning glow and brightened. Many people shouted: "The sun is over there, over there!" " "Calling calling, there are five or six suns, and I firmly believe that the sun rises in the brightest place.

The early morning wind whistled and blew the pine trees, and the surrounding blurred mountains and trees gradually became clear. In this artistic conception, you can really forget yourself, but there are too many people around you and it's too noisy. I always feel that such scenery should be quiet and uninteresting. As long as two people are back to back, facing the place where the sun rises, without words, they can only have a wonderful picture of the sunrise.

Finally, we saw a part of the sun coming out. The fog was too heavy that morning.

We saw the sea of clouds, a vast expanse of white in the distance, floating around. At first we thought it was Taiping Lake. Looking at it carefully, isn't it a sea of clouds drifting between and around the peaks? I really made a fairy on the top of the lamp, and it was on the top of the lamp.

Standing on the edge of the cliff at 1840 meters, the fog lingered from the foot, gradually rose to the legs, waist and shoulders, and finally the whole body was covered with fog, as if it had entered an illusory place, and the huge mountain wind blew people directly. I personally realized what "fragility" was.

I put on my raincoat, opened it wide, faced the wind, spread my arms, and my clothes floated. Then I stopped for a while, and with a click, the desert sunshine of "Dapeng spreading its wings" stayed.

The temperature at the top of Guangming Mountain is very low. On that day, we were only 17 degrees at the top of the mountain, wearing shorts, T-shirts and raincoats. ...

On a beautiful sunset evening, when we went out for a walk, we suddenly felt suddenly enveloped in a beautiful sunset glow.

Looking up at the western sky, I found a large rosy cloud.

Clouds slowly change shape, sometimes like a fierce lion, sometimes like a tall and strong giant, and sometimes like a mountain dyed with many colors.

The orange light beam penetrates the clouds and hits the earth directly, as if the sky had been opened, and a magnificent musical is about to be staged.

I was deeply intoxicated by the charming scenery.

Many grayish-black clouds came from all directions, and gradually, the original weak sunshine was covered by accumulated clouds.

The light dimmed, as if someone accidentally knocked over the ink bottle, and the sky was stained with a layer of gray and black.

Gradually, the dark clouds dispersed again.

The sun reflected the gentle afterglow on the ground, and the light was not dazzling at all.

Flowers, trees, all dyed orange, even I turned orange! I am bathed in the sunset glow, which is really refreshing! I really want to open my throat and sing a song to express my unbearable mood; I really want to write a poem with my pen, praising the beauty of this sunset! What a charming sunset glow! An idea flashed through my mind: isn't the childhood we live in exactly the same as this beautiful scenery? The same short, the same gorgeous and wonderful.

If cherished, there will be unexpected gains; If you waste it, it will be fleeting and merciless.

I love this beautiful sunset! ...

The change of natural landscape composition is just a little urgent, take your time, and forget to give you another reward by the way! "lixi Li, Li" is as expensive as oil, and the spring rain falls on the earth.

The fine spring rain is fluttering, and the peach blossoms in the orchard are red; Sprinkle on the treetops to dye green willow buds; Fall in the fields to nourish crops; Fall on the pond to wake the frog ... Green the willows by the river and red the apricot flowers.

In an instant, raindrops fell from the sky like thousands of soldiers.

It falls on the pink petals of morning glory and rolls like thousands of colorful gems.

Raindrops fall on the pond, and the calm pond ripples.

Looking at the raindrops carefully, I can see that the raindrops are scattered, gathered, retreating, retreating and advancing.

It is so unpredictable that even the most talented painter can't draw it! Look, how beautiful the azaleas are! The blooming petals crowded together and danced like a colorful girl.

Flowers in bud are colorful, some swaying in the wind, some shy.

A large disc-like leaf is green and flawless, and the water drops are more transparent than pearls rolling on it, making the azaleas more charming and moving.

Look at the hungry willows, they are greedily sucking the dew of spring.

Countless willow branches that seem to be decorated with emeralds droop like soft ribbons.

These naughty willow dolls float around freely, just like a group of carefree little angels.

Countless small drops of water fell on the willow with Ana stretched out, as if to put a crystal coat on the willow, which was particularly touching.

Look at the pink peach blossoms, one by one, blooming all over the branches.

They are like groups of urchins, scrambling to let people see their gorgeous charm.

Water drops make peach blossoms look beautiful and make people feel relaxed and happy.

After the spring rain, the campus is more vibrant.

Let a hundred flowers blossom and start to compete again; The weak and tenacious grass was straightened by the spring rain; Beautiful azaleas opened a more brilliant smiling face; The greedy willow tree looks more enchanting and charming; Pink peach blossoms are even more shy ...

The natural and quietly changing composition life has quietly changed. In fact, big data has begun to quietly change our lives.

Online shopping is becoming a favorite shopping method for consumers. 20 12' s "Double Eleven" war has made many netizens addicted to online shopping.

Maybe you don't know, in fact, relying on the ability of big data analysis and prediction, some savvy retailers are collecting and mining consumer big data from a more personalized and direct target customer level, especially in important holiday needs.

Big data can handle a wide range of activities, including effective marketing activities, and can be used to sell and promote customers' preferences in view of customers' online purchase behavior, thus realizing social e-commerce and inventory optimization.

For example, big data analysis software may enable retailers to conduct directly related promotion and marketing activities, motivate consumers to buy online, and track the resulting sales transactions.

At the same time, as a result of big data, retailers can monitor and adjust promotional activities in real time, maximize consumption, improve profitability, and generate maximum income in a short time in key periods.

"In the past, empirical decision-making based on surveys was more used in decision-making. With the help of big data analysis, objects can be quantitatively analyzed, making decision-making more scientific.

Han, an analyst at China Electronic Information Industry Development Research Institute, said that Taobao has set up a cloud computing center, which can better handle consumers' consumption habits and seasonal changes by using big data, so as to formulate its own marketing strategy and inventory allocation more accurately and make decisions more rational.

Trident Marketing is a direct selling company, and its customers include brands such as DIRECTV.

With the help of IBM's big data analysis software, they can even predict the best contact time for customers and whether customers will cancel the service.

Its revenue increased by 10 times in just four years, its sales increased by 10% in the first two months after product deployment, and its customer churn rate decreased by 50%.

Big data can also be a doctor! I once participated in the American intelligence game Jeopardy! IBM's supercomputer Watson has been used to assist doctors in auscultation.

At present, some American medical institutions have begun to cooperate with IBM in order to avoid the negligence of doctors. Now Watson will accompany the doctor to auscultate, and after auscultation, he will list possible diseases through symptoms. Doctors may only think of three or five symptoms after consultation, but Watson will help him list as many as 20 symptoms from the perspective of massive data analysis, which can greatly reduce the chance of doctors' negligence. Doctors will know after reading Watson's analysis report that they can ask more patients.

Big data will make business maintenance more convenient.

Taking a financial enterprise as an example, Xiao Bing told us that in the past, traditional data processing methods required three shifts 24 hours a day. Now, after PureData goes online, only six people are enough, which will bring greater convenience, reduce greater costs and enhance competitiveness.

Talking about the changes that big data may bring to life, Han said: "Big data will have an all-round and profound impact on the whole society from personal, social life, business, law, morality and other aspects, with more changes. We can't predict, but there is no doubt that the dramatic impact of big data on life is an irresistible fact.

Composition: After the change of nature, human science and technology have gradually developed in the new century.

Everything has changed and become so beautiful.

The only regret is that a leopard cannot change his spots.

After entering the new century, people take cars, planes, ships and rockets ... grandparents will surf the Internet, and parents have become fond of learning in order to adapt to the information age.

In front of all the beautiful things, people are a little negligent and naturally change.

Nature has changed.

Once dense trees, lively white rabbits, scheming foxes ... everything is gone.

Nature has changed, becoming lifeless and unhappy.

Smoke and sewage from human factories are doing harm to nature unscrupulously, and no one has found that nature has changed.

Nature has changed.

The orchard where I used to hide and seek when I was a child is gone.

You can only see a large white wasteland.

Listen to the few families who live here: in the future, we will also move out.

Say what it is, make a factory.

Good land! The happy garden of childhood no longer exists.

The reality is cruel, leaving us only memories.

After entering the new century, human beings have changed, naturally, and everything has become so thorough ... The composition section of the study abroad network brings you the most authoritative and diverse composition about the unit, and I hope you will like it.

Primary school students' composition "Changes in Nature in Spring" Nature is so beautiful! Lush mountains, like strips of Youlong, are continuous and stand tall in the clouds.

The sky is endless, just like a wisp of green yarn hanging gently over the mountains.

Only occasionally a few white and flawless clouds float gently into the distant sky ... You see, towering trees stand around the mountains, full of vitality and different shapes.

Small green leaves on the trees decorate the beautiful land.

The soft grass is like a green carpet.

There are all kinds of beautiful flowers on the carpet-like grass.

These flowers are as yellow as gold, as red as blood, as blue as the sky … colorful and beautiful.

In front of the grass, the song never stops.

Think about it. who is it? Ah, it turned out to be a brisk stream.

The stream is winding and crystal clear, and even the sand at the bottom can be seen clearly.

At this time, a flock of birds flew in the sky. Encouraged by their parents, they spread their wings and flew to the vast blue sky, and soon disappeared.

Ducklings are not bad either. Under the guidance of their mother, they waddled down the river, swam briskly and shouted happily. The most interesting things are rabbits and turtles.

They're going to race the tortoise and the hare again.

Hey, they are all gearing up and want to win the gold medal in the competition! Spring in nature is always so wonderful and vivid.

No wonder when the footsteps of spring come, the earth will put on new clothes to welcome this beautiful spring girl!

Composition about the changes of natural scenery in summer? Summer is a fragrance.

Lotus blooms with delicate petals and gives off charming fragrance, just like a slim girl wearing a pink veil.

Green lotus leaves also come to put green shoes on the lotus, which looks more beautiful. It's really "the lotus leaf is infinitely green the next day, and the color of the lotus flower is different the next day"! Summer is sweet.

In the field, green watermelons are waiting for people to pick them! Split it with a knife and the red juice will burst out. Take a piece and taste it. That cold and sweet feeling will surround you for a long time.

Summer is red.

Yang Wanli, a poet in the Tang Dynasty, wrote in his poem: "After all, the scenery of the West Lake is different from the four seasons in June; Lotus leaves will not turn green the next day, and lotus flowers are particularly bright red in the sun.

"You see, these pink lotus flowers are like fairies bathed in the lake with veils.

Shy and eager to talk, Ying Ying is about to drip, and the fragrance is floating in the wind, which is refreshing.

Some buds are sprouting; Some are in bud, and the flower bones stick out like torches; Some compete to open, revealing delicate little lotus flowers.

Summer is green.

If you walk into our school, you will find the campus is covered with green: big trees and small trees are green, and the grass is green.

The banyan tree is tall and straight. Looking up, a bright green leaf shines in the sun, showing endless vitality.

The French phoenix tree is as tall as the banyan tree and is also a green tree. On the branches extending around, palm-like green leaves are dense, leaving a shade for the campus.

If the banyan tree is a mighty guardian on campus, then the buttonwood tree is a big green umbrella.

There are many other trees, all of which have faded from the yellow left in winter, showing the green of a tree.

In the pond, the lotus flower that bid farewell to the bud is blooming with a beautiful smile. Under the breeze, a green skirt danced, Tingting's charming and reserved posture, and in the condensed fog, a graceful woman recited the poem "Lotus beads are broken and round". Beautiful branches are showing you the summer customs and making you feel uncomfortable.

When I suddenly look back, it is already "the lotus leaf is infinitely blue the next day, and the lotus is different in color."

Please comment. thank you

Observing the characteristics of a natural change, composition 400-word fish pond Sunset In the evening, after dinner, I took a long step to the fish pond outside my dormitory to see the beautiful scenery of the sunset in the fish pond.

Ah! The sunset glow, how wonderful, runs like a horse for a while, roars like a lion for a while, and blooms like a flower for a while ... I look at it and feel light all over, as if I have become a sunset glow.

After a while, a touch of sunset glow shone brightly. I opened my eyes slightly, and suddenly there appeared seven colors: red, orange, yellow, green, cyan, blue and purple. My body seemed to be wrapped in colors.

I looked down and saw that the green fish pond was like a gourd-shaped gem.

The sunset glow sprinkled colorful soft light on the fish pond, just like inserting velvet flowers in clear water.

The fish in the pond swam leisurely in groups of three or five.

Sometimes they huddle together, as if whispering.

Sometimes they stare at the sunset glow as if talking about its strangeness.

The swimming of fish attracted me, and a strange sight seemed to appear before my eyes: groups of golden carp seemed to be halos in the pond.

When I looked up, I saw the sunset glow in the sky, like flocks of colorful fish swimming in the sky.

There is a fountain on the left side of the fish pond, and the water sprayed is like colorful fireworks and crystal pearls, and the sunset glow is even more colorful.

These drops of water drop on the surface of the water, causing a little halo and rippling around like colorful rings ... There is a hexagonal pavilion with glazed tiles on it in the pond.

People often play chess here to get rid of work fatigue.

The strange rocks around the fish pond are rugged and varied, and the sunset glow shines on them and turns them into gems.

Some of the strange stones are like the Monkey King scratching his head, and some are like overlapping mountains in a bonsai ... There are countless weeping willows planted beside the fish pond.

Its branches are graceful, a gust of wind blows, and the weeping willows sway gently. Now it is wearing a colorful sunset dress, just like a fairy in a colorful skirt, dancing ... The colorful night scene of the fish pond makes people want to see it for a long time, and they also want to sing a poem and draw a colorful picture ... As night falls, the sunset disappears, a bird flies over the water, and the fish also want to draw a colorful picture.

Write a composition about nature. I love nature! Look at that sleepy puppy, as if it had just given birth. I also like the four seasons like a magician, sometimes it's cold and sometimes it's hot, and it floats around. I also like salty rain to cook for my mother! I love nature! I don't like terrible typhoons, I just like warm sunshine. I don't like fierce tigers, I like docile kittens; I don't like the dark night sky either. I like the starry night sky. I love nature! I like to see strong trees and the strong sunshine in spring. I also like plump cats like balloons. I prefer the gentle moonlight, as if my mother lit up the earth. For me, nature is a pure land in my heart. I can't live happily without it. Of course I won't be happy if the air is not fresh. Only nature is the most precious part in my heart, so we should take good care of it. Don't let others destroy nature. Nature and I are shared by all mankind, but when I was a child, I had more opportunities to contact nature than ordinary people. I grew up in Zhushan, so nature is closely related to me. Growing up in the mountains, you should be familiar with everything in nature, including the terrain in the mountains, and pay attention to the possible wild animals. Poisonous plants, especially snakes, have always been children's nightmares. Of course, plants are inevitable. If you are stabbed by poisonous vines or flower stems, the consequences will not end well. Fortunately, the elders are properly educated, and this has rarely happened in recent years. In this nature, there are many terrible things, and of course there are beautiful places. Sometimes we can't stay at home any longer, so our brothers will take us for a walk in the mountains, to streams, waterfalls, mountains, and maybe even yell at the top of the mountain, which always makes us. When you reach the waterfall, you pull out the water and float; When we arrive in the mountains, my brother will teach us how to live in the mountains. This kind of journey always makes us have the heart to play and learn knowledge. This also gives me and other friends the knowledge of living in the mountains. Sometimes when we have a holiday, we will plan camping and go to different places, which will make us have the ability to live independently and make us more sensible. Nature was my childhood friend, but now my friend is taking revenge on mankind. Natural disasters, such as seawater intrusion, typhoons and earthquakes, are my friends' silent demands for mankind. They hope that humans will not make holes in its body or work on its face. When it becomes unable to serve mankind, war will be triggered and mankind will be challenged more severely. As a friend of nature, I don't want this to happen. In short, let it go! Work hard for our nature! Nature and I, sometimes scattered in fields and villages. The wind passed by and thousands of flowers were bathed in warm sunshine, which made me like Jenny's beautiful scenery since I was a child. I am far away from the prosperity of the city, and come to Yuan Ye in nature, wandering in a grassy grassland. I love floating white clouds, I love blue sky, I love lovely birds, and I love them even more. Flowers and plants tremble for me, the waves are tangyang for me, and birds sing for me. Unconsciously, I have been immersed in it. Walking out of the yard at night, watching the bright moonlight and listening to the wonderful insects, I suddenly felt very comfortable. Under the clear sky, there is an endless sea, which is connected with the sky and the sky is connected with the sea. Instantly feel the smallness of people, such as a drop in the ocean, watching waves after waves. It shocked my heart and made me feel sad for mankind. The inspiration from nature is so profound that it makes people feel warm, purifies the soul and adds colorful features. In people's world, maybe everyone needs this tonic to adjust our busy and tense life and make it an indispensable source of power. But many people are busy with their work, but they neglect to appreciate her and get her friends. It's time to stop and feel the beauty of nature with your heart, which will definitely make you tired and reap unexpected results! Scars on nature None of us want to have a beautiful home, and nature has a close relationship with us. Now people only pay attention to development and utilization, but not to environmental protection. For example, littering with scraps of paper, peels and garbage is more serious, because people destroy the environment for convenience. The coal mining enterprises in our town are an example. Coal cinders are everywhere, and dirty water is flowing everywhere. Wherever people go, they always smell a disgusting smell. It is the waste residue, waste liquid and waste water randomly discharged by family members in the mining area. They pollute not only the environment but also the air. There are also coal mine production and processing, which will discharge some things such as; Harmful gases such as carbon monoxide, carbon dioxide and sulfur dioxide not only pollute the environment and air, but also do great harm to crops. This is the trauma that people bring to nature for the convenience of development and life. Water pollution in our town is also a big problem. There is a reservoir called Haizi, which used to be a good place for people to linger. At that time, the water was clear and bright, like blue crystal. There are many small fish playing in this blue crystal. Because people throw it around here, this blue crystal becomes dark and pale, and the fish here are in a "haggard" state, because they say goodbye to their loved ones every day, and they will gradually say goodbye to the beautiful nature. This is another trauma that people throw into nature. Friends! Let's join hands and smooth the scars of nature with practical actions! I love nature, and looking up at the ever-changing clouds in the sky can't help but give me a lot of reverie; Looking down at the green lawn on the ground, I can't help but feel very comfortable and quiet. Oh! I love nature. The aroma is fragrant, and I look at the misty green hills in the distance, as if covered with a layer of gauze; Several birdsongs on the branches are particularly crisp and pleasant. I like to stand on the bridge at dusk. ...

The weather turns cold, the leaves turn yellow, the fruits mature, and the geese fly south.

Introduction: In autumn, the most obvious change of natural landscape is in trees. A lot of fallen leaves will be cleaned up in the city, and many tourists will flock to the mountains to see the red leaves.

Autumn, the third season of the year, is a transitional season from summer to winter. The lunar calendar is from beginning of autumn in July to beginning of winter in September, the solar calendar is from 9: 00 to 1 1, and the astronomical vernal equinox starts from the winter solstice.

The standard for meteorologists to study phenology is: after the intense summer heat, the average temperature for five days is stable below 22 degrees, which means that it is autumn, and it is over when it is below 10 degrees.

Good eating habits should be developed in autumn: when autumn comes, the weather turns cold and people's appetite is getting better and better. However, many people still keep the original habit of skipping breakfast and eating more at dinner. In this dry autumn, it will do great harm to people, so it is very important to change their diet.

Experts remind that three meals a day should be eaten on time as much as possible, so that the spleen, stomach, liver and gallbladder can operate rhythmically to avoid food accumulation and indigestion.
