Write a composition with phenological knowledge

1. I still remember the phenology of summer, and my grandmother's singing comforted me.

I sat on the creaking bamboo chair, and grandma shook the banana fan, feeling a twinge of coolness. You can also contribute "Grandma, will you keep slapping me?" I asked with my head down.

Grandma put down the fan, stroked my head and said kindly, "Of course not, silly child, grandma will go to heaven in the future." "I was in a hurry, tugging at my grandmother's skirt:" No, grandma will go to heaven, no … "Grandma was silent, just stroking my head, and then she said," I'm not afraid. When you miss grandma, you can reach out and see heaven and grandma in front of the sun. "

Of course, I didn't quite understand it when I was a child, but I nodded puzzled. Ruthless illness still took my grandmother's life. I was seven years old that year.

I didn't cry the moment grandma's body went into the coffin. I comforted myself: I can still see grandma. She said, you can see her by pointing to the sun.

Looking at grandma's pale face, I have an impulse to cry, no! I won't cry! I suddenly pushed away to see my mother, ran to another room, quietly squatted down and prayed silently: Grandma, don't lie to me. When I point my finger at the sun, you must appear ... The next day, the weather was fine. I couldn't wait to try the method taught by my grandmother and point my hand at the sun, but all I saw was more dazzling sunshine, and there was no heaven or grandma at all. I tried several times and the result was still the same.

Maybe it's too far to go to heaven, and grandma hasn't arrived yet ... I comfort myself like this. A few years later, my grandmother didn't teach me anything, and I began to wonder if my grandmother was lying to me. For so many years, I can only look at grandma's photos or stand in front of her grave.

Every time I stand in front of grandma's grave, I feel very sad. Grandma, why did you lie to me? Why go to heaven? Will you remember me in heaven? In the summer afternoon, you shook the banana fan to enjoy the cool for me; Every morning in the summer vacation, you comb my hair with a horn comb; You know best what I like to eat, and you always cook good food for me. After dinner, take me for a walk in the wild ... do you remember these? When I sleep at night, I often dream of your smiling face ... Grandma, can you ask God for leave and come back to see me ... One morning a few years later: I was helping my mother pack things that morning, and a very beautiful little box caught my eye.

"Mom, what is this?" "... I don't know, see for yourself. "I opened it, and there was a black thing inside.

"Oh. I remember, my grandmother left this for you. She said it was her only valuable thing, a silver tooth. "

"Why did you give it to me until now?" "I forgot, too. I think such silver teeth are useless ..." "No! Useful! " I shouted. Grandma, I know you will remember me. You didn't lie to me. I can see you through my hands. Only then did I understand what grandma meant, and I realized that grandma loves me very much and wants to be with me ... Grandma, your silver teeth are the best gift I have received since I was a child.

Grandma ... Postscript I reached out my hand again and pointed my finger at the sun. Yes, I saw it. Heaven is beautiful, grandma. You live well there, don't you? You will always look at me, right? .

2. An essay on phenology. Nature's words can help us understand information and increase our knowledge.

If swallows fly high in the air and look small, there will be fine weather. A crow with a white beak flew in and said that spring had arrived at the gate.

Flying cranes can tell people that the hot weather has passed without a calendar. Look at the white clouds in the sky that day /This is the language of nature:/White clouds are floating high. /It must be sunny tomorrow.

Look at the ants on the ground. /This is also the language of nature:/Ants are busy moving,/Take an umbrella when going out. Tadpoles swim in the water. /Is it like a black comma? /Nature writes on the water:/Spring comes to the world.

These geese are flying south in formation. /Isn't it like a string of ellipsis? /Nature writes in the blue sky:/Autumn is just around the corner. If the tree is cut down,/you will find annual rings-/only one annual ring grows,/this is a natural language.

If you catch a big fish,/there are rings on the fish scale-/one year old,/this is the language of nature again. Nature embeds trilobite fossils in the Himalayas.

/This is telling people:/It used to be Wang Yang. Nature planted a "boulder" on Lushan Mountain in the south of the Yangtze River to remind everyone that there was a cold glacier here.

You have learned to read for a long time, and you can easily read any sign on the street. You won't go to the barber shop to buy medicine, and you won't go to the drugstore to get a haircut.

If no one is with you, you can easily find your way, just give you the correct address, street name and house number. Words are really good things.

If you know this word, you can read the thickest book and know everything in the world. But there is another set of words that everyone who wants to be really knowledgeable should know.

This is the writing of nature. It always has thousands of letters.

Every star in the sky is a letter. Every pebble under your feet is also a letter.

For those who don't understand this writing, all stars are the same thing. However, some people can recognize the names of many stars and tell how they are different from other stars.

Just as the words in a book are composed of letters, the stars in the sky also form constellations. Since ancient times, when sailors need to find their way at sea, they will read books written by stars.

You know, boarding a boat on the water just leaves no trace, and there is no road sign with an arrow that says "Go north from here". But sailors don't need such signs.

They have a compass with a phosphorus needle, and the magnetic needle always points to the north. Even if they don't have a compass, they won't get lost.

They looked at the sky and found Ursa major in many constellations, and Polaris was also in Ursa major. The north is beyond Polaris.

Clouds are also the letters in the big book of the sky. It talks about the future as well as the present.

In the best weather, according to the clouds, thunderstorms or lewd rain can be predicted. Sometimes, in hot summer, a white Yunshan stands in the distant sky.

Two sharp points protrude from this Yunshan to the left and right. The mountain has become like an anvil in a blacksmith's shop.

Pilots know that anvil clouds are a precursor to thunderstorms. Might as well stay away from it.

If you fly in it, it will destroy the plane-the wind there is too strong. Birds, the messengers of the sky, will also teach many skills to those who observe them carefully.

If swallows fly high in the air and look small, there will be fine weather. A crow with a white beak flew in and said that spring had arrived at the gate.

Flying cranes can tell people that the hot weather has passed without a calendar. The sun is still very hot, and it is a calm sunny day.

At this time, there was a strange and uneasy voice in the distance, as if someone was echoing each other in the sky. The sound is getting higher and higher and closer.

Staring at the sky, you can finally recognize a fuzzy spider web, as if it had been blown by the wind. The spider web flew near, and I picked it up and saw that it was not a spider web, but many birds with long necks.

They lined up in herringbone and neat formation, flying towards the sunny forest. But soon I can't tell these birds apart. It looks like cobwebs again.

In the blink of an eye, even the cobwebs disappeared without a trace. They seem to melt in the sky. Only voices came from far away, as if to say, "Goodbye! Goodbye! See you next spring! " You can learn a lot of new things by reading the big book Sky.

Even The Land Under Our Feet is a very interesting book for people who can understand it. Now, on the construction site, the shovel of the excavator hit a gray stone.

In your opinion, this is just an ordinary stone, but for those who know natural characters, this is not an ordinary stone, but limestone. It is changed from broken shells. You know shellfish are the inhabitants of the ocean.

It can be seen that in ancient times, this place, which is now a city, was once the sea of Wang Yang. Sometimes, when you walk in the forest, you will suddenly see a huge granite stone lying in the middle of the forest, covered with moss, just like fur.

How did it get here? Who has the strength to move such a big stone into the forest? Besides, how did it get through the dense forest?

After beginning of spring, the earth gradually woke up from a deep sleep. Snow and ice melt, plants sprout and all kinds of flowers bloom. Two months later, the swallow came back, and soon the cuckoo came. So it becomes hot summer, which is the period when plants breed fruits. In autumn, the leaves of plants gradually turn yellow and fall in the autumn wind. The wild geese in the north fly to the south. Insects active in fields and grasslands have also disappeared. Everywhere I go, there is a scene of grass rot, preparing for the snowy winter. This is true year after year in the temperate and subtropical regions of the earth. For thousands of years, working people have paid attention to the relationship between natural phenomena such as vegetation decline and migratory birds and the climate, and arranged farming accordingly. The apricot blossoms are in bloom, as if nature is telling them to plant the land quickly. When the peach blossoms are in full bloom, it seems to imply that we should plant millet as soon as possible. The cuckoo began to sing, and the working people knew what it was singing: "Grandpa and grandma, after cutting the wheat and inserting the grain." In this way, it seems that flowers and birds sing, grass grows and warblers fly, all of which are the languages of nature. These natural phenomena were called phenology by working people in ancient China. Phenological knowledge originated very early in China. Many agricultural proverbs handed down from ancient times contain rich phenological knowledge. It has developed into a science, namely phenology. Phenology records the growth and decline of plants and the reproduction of animals, such as peach blossoms and swallows, so as to understand the climate change with the passage of seasons and the impact of this change on animals and plants. O(∩_∩)o I hope I can help you! O(∩_∩)o Please give your praise or adoption in time.

After beginning of spring, the earth gradually woke up from a deep sleep. Snow and ice melted, vegetation sprouted, and all kinds of flowers bloomed for the first time. Two months later, the swallow returned lightly. Soon, the cuckoo also came. So it becomes a hot summer, that is, the period when plants breed fruits. In autumn, when the fruits are ripe, the leaves of plants gradually turn yellow and fall in the autumn wind. The geese flew south, and the insects active in the fields and grass disappeared. Everywhere I go, I see a scene of falling grass, ready to meet the snowy winter. In the temperate and subtropical regions of the earth, this is the case year after year, and it goes on and on.

For thousands of years, working people have paid attention to the relationship between natural phenomena such as the rise and fall of vegetation and the coming and going of migratory birds and the climate, and arranged farming accordingly. Apricot blossoms are in full bloom, as if nature is preaching to cultivate the land quickly; Peach blossoms are blooming, which seems to imply that we should plant millet quickly. The cuckoo began to sing, and the working people understood what it was singing: "Grandparents, cut wheat and transplant rice." In this way, flowers and birds sing, grass grows and warblers fly, all of which are the languages of nature.

These natural phenomena were called phenology by working people in ancient China. Phenological knowledge originated very early in China. Many agricultural proverbs handed down from ancient times contain rich phenological knowledge. In modern times, using phenology knowledge to study agricultural production has developed into a science, that is, phenology. Phenology records the growth and decline of plants and the reproduction of animals, such as peach blossoms and swallows, so as to understand the change of climate with the passage of seasons and the influence of this change on animals and plants. Phenological observation uses "living instruments", which are living organisms. It is much more complicated and sensitive than meteorological instruments. Phenological observation data reflects the synthesis of climatic conditions such as temperature and humidity, and also reflects the influence of climatic conditions on organisms. When applied to agricultural activities, it is simple and easy to master. This is the importance of phenology to agriculture. Here is an example.

According to the phenological records in Beijing, the flowering of peach, apricot blossom, apple, elm leaf plum, Xifu begonia, clove and Robinia pseudoacacia in196/kloc-0 is about ten days later than that in 1968+0, and five or six days later than that in 1960. According to these phenological observation data, it can be judged that the agricultural season in Beijing 1962 came late. However, crops such as peanuts planted in the early spring of that year were planted according to the date of previous years, and the result was frozen by low temperature. This loss can be avoided if we can pay attention to the phenological delay and choose the appropriate sowing date.

What factors determine the coming of phenology?

The first is latitude. The farther north the peach blossoms bloom, the later the migratory birds come. It is worth pointing out that the days of phenology difference between north and south change with the seasons. Chinese mainland has a remarkable climate, and Leng Xia is hot in winter. The temperature difference between north and south is very wide in winter, but not much in summer. In spring, early spring and late spring are different. For example, in March and April of early spring, Nanjing peach blossoms bloom 20 days earlier than Beijing, but by the end of spring and early May, Nanjing Robinia pseudoacacia only blooms 10 days earlier than Beijing. Therefore, in North China, it is often felt that spring is short, winter has passed and summer has arrived.

Longitude difference is the second factor affecting phenology. All offshore areas are warmer in winter than inland areas at the same latitude, and colder in spring. Therefore, the arrival of spring in coastal areas is a few days later than that in inland areas. For example, the latitude of Dalian is about south of Beijing, but in Dalian, forsythia and plum blossoms bloom one week later than Beijing. For example, Jinan apples bloom in mid-April or Grain Rain Festival, and Yantai will go for a long summer. The latitudes of the two places are almost the same, but Yantai is near the sea, and spring comes late. The third factor affecting phenology is the height difference. Phenological phenomena such as flowering of plants are late in spring and summer, and deciduous trees are early in autumn. However, the study of this factor should take into account special circumstances. For example, at the turn of autumn and winter, in clear Wan Li, the temperature at a certain height is inversely proportional to the height. This is called inversion layer. Because cold air is heavy, it flows to lower places on windless nights. This phenomenon is very obvious in autumn and winter in mountainous areas, especially in the morning of these two seasons. It is often found that there is frost at the foot of the mountain and frost at the mountainside. The introduction of tropical crops in hilly areas of South China is very successful, but it is not suitable at the foot of the mountain.

In addition, there are differences between ancient times and modern times in the morning and evening when phenology comes. According to the long-term phenological records in southern England, comparing the ten-year average of 174 1 to 1750, we can see that the latter is 9 days earlier than the former. In other words, spring is nine days ahead of schedule.

Phenology is a science close to ecology in biology and agrometeorology in meteorology. The study of phenology is first to predict the agricultural time and choose the sowing date. Besides, there are many meanings. Phenological data has important reference value for arranging crop zoning and determining the date of afforestation and seed collection. It can also be used to introduce plants into areas with the same phenological conditions, and can also be used to avoid or reduce the harm of pests. There are a large area of mountainous areas in China that can be cultivated, but the adaptability of climate and soil in many places to crops in mountainous areas remains to be investigated. In order to promote the development of agriculture in mountainous areas, it is necessary to carry out phenological observation in mountainous areas.

Phenology is a science related to high agricultural yield. It is necessary to further strengthen phenological observation, understand the language of nature, and strive for greater gains in agriculture.

5. Write a composition about phenology. 500 words. Peach blossoms outside the bamboo are three or two, and the spring water heating duck prophet. (Su Shi wrote Hui Chong's Night Scene of the Spring River) In early spring, ducks first felt the spring water heating and played in the water.

"Frozen waterfowl live together in cold weather, and one hundred is a group play. When pedestrians can't stand it, they suddenly smell the ice ring in Qi Fei. " (Qin Guan's Return from Guangling) At the end of winter, water birds are dependent on each other, and there is the sound of ice, and birds fly in surprise. Ducks and birds are messengers of spring.

"It rains at home in Huangmei season, and frogs are everywhere in the grass pond." The three images in Zhao Shixiu's poem "A Heart on a Water Threshold" show the seasonal characteristics of plum blossom and Huang Shi in late spring and early summer.

Huang Chao wrote the title of chrysanthemum: "The west wind is rustling all over the courtyard, and the cold butterfly is hard to come." Chrysanthemums wither, butterflies wither, although there is no word "autumn", but the coolness of autumn is coming.

As for Li Bai's "Xia Sai Qu", it leads readers to another world: "In May, the snow in Tianshan Mountain is cold without flowers, and the willow is heard in the flute, but no spring scenery is seen." May is in midsummer, and it is already the day when all the flowers in the mainland are dying. However, Tianshan Mountain (Qilian Mountain), located in the northwest frontier, is still covered with snow, and there are no willows and flowers, indicating that there is neither summer nor spring and autumn in the Yellow River basin above 4000 meters above sea level. It is not difficult to see the great difference in climate between the mainland and the Great Wall.

The agricultural and military activities of the ancients are also often seen in ancient poems involving phenology. For example, Fan Chengda's "Four Seasons of Pastoral Fun": "Butterflies have entered cauliflower, and no guests have come to Tianjia for a long time." These two poems, written in the countryside in the late spring of Jiangnan, set off the busy farming of peasant women through the description of butterflies entering cauliflower. Let's look at Wen Tong's "Morning Clear to Baoenshan Temple": "The smoke is far away, and the sky is high. Barley doesn't enter the nursery at night, and young silkworms lie alone. " The first part depicts a vivid picture of wild birds flying in the distant mountains and forests; The second part is about the busy scene of peasant women harvesting wheat, whole vegetables, picking mulberry and feeding silkworms at the turn of spring and summer, which is kind and touching. And Lulun's "high in the faint moonlight, geese flying, Tatar chiefs fleeing in the dark. While we chase after them, the horse carries a light load, and the bow and sword bear a burden of snow "(the third part of the next song) is about marching and fighting: the enemy fled at night, and the geese were surprised to fly, which aroused the vigilance of our general and led troops to chase after the enemy, fully demonstrating the heroic spirit of the people of China.

Bamboo branch

Year: Tang Author: Liu Yuxi School: Four Unique Categories:

Willow and green Jiang Shuiping,

Smell the songs on the Langjiang River.

Sunrise in the east and rain in the west,

The road is sunny or sunny.

After beginning of spring, the earth gradually woke up from a deep sleep.

Snow and ice melted, vegetation sprouted, and all kinds of flowers bloomed for the first time. Two months later, the swallow came back, and soon, the cuckoo came too.

So it becomes a hot summer, that is, the period when plants breed fruits. In autumn, when the fruits are ripe, the leaves of plants gradually turn yellow and fall in the autumn wind.

The geese flew south, and the insects active in the fields and grass disappeared. Everywhere I go, I see a scene of falling grass, ready to meet the snowy winter.

In the temperate and subtropical regions of the earth, this is the case year after year, and it goes on and on. For thousands of years, working people have paid attention to the relationship between natural phenomena such as the rise and fall of vegetation and the coming and going of migratory birds and the climate, and arranged farming accordingly.

Apricot blossoms are in full bloom, as if nature is preaching to cultivate the land quickly; Peach blossoms are blooming, which seems to imply that we should plant millet quickly. The cuckoo began to sing, and the working people understood what it was singing: "Grandparents, cut wheat and transplant rice."

In this way, flowers and birds sing, grass grows and warblers fly, all of which are the languages of nature. These natural phenomena were called phenology by working people in ancient China.

Phenological knowledge originated very early in China. Many agricultural proverbs handed down from ancient times contain rich phenological knowledge.

In modern times, using phenology knowledge to study agricultural production has developed into a science, that is, phenology. Phenology records the growth and decline of plants and the reproduction of animals, such as the arrival of peach blossoms and swallows, so as to understand the climate change over time and the impact of this change on animals and plants.

7. Natural language use explains language methods and sentences. 1. Grasp the opening paragraph of the text as a whole. Writing the phenological landscape of nature vividly and explaining it in the description is like showing a picture of the scenery of the four seasons, which is both fascinating and memorable, stimulating readers' interest in reading.

Phenological phenomena in nature, such as the prosperity and withering of vegetation and the coming and going of migratory birds, actually play a role in predicting agricultural seasons. From this perspective, phenology seems to be a "natural language" for transmitting information. The goal of the topic is "natural language", which is actually an intuitive statement of "phenology"

(1) Clear thinking and distinct levels. This paper can be divided into four parts: the first part (1 ~ 3) leads to what is phenology and phenology.

The second part (paragraphs 4-5) expounds the importance of phenological observation to agriculture. The third part (paragraph 6 ~ 10) explains the factors that determine the coming of phenology.

The fourth part (paragraph 1 1 ~ 12) expounds the significance and function of studying phenology. These four parts are closely related and the materials are arranged in logical order.

The first part explains the object of phenology research, starting with the changes of phenology in four seasons, and describes the changes of phenology in just a few hundred words, which is vivid and highly summarized, so that readers can have an intuitive understanding of phenology. Then, taking specific phenomena as examples, the author tells readers that these are poetic languages such as "lush vegetation, migratory birds coming and going", "flowers and birds singing, grass growing and warblers flying" and so on, which are "the languages of nature".

On this basis, from ancient times to modern times, from origin to development, the author naturally leads to what is phenology and what is phenology. This is an explanation from the outside to the inside.

The second part, the topic turns to agriculture, and illustrates the importance of phenology to agricultural production with concrete examples. This part also forms a reference with the end of the article.

The third part of the article goes on to talk about four factors that determine the arrival of phenology: latitude, longitude, height difference, ancient and modern difference. This is the main part of the article.

The influence of the four factors is different, from large to small, arranged in turn and carried out in an orderly manner. Latitude and longitude are different locations on the earth. The third factor is the difference in the same place. These three factors are all spatial factors, and the last one is time factor, which is a continuity from space to time.

Use a rhetorical question to explain the four factors, and then use connectives such as "first", "second", "third" and "besides" to make this part clear. It is worth noting that every question is illustrated with examples, so that the article is convincing and easy to understand.

The last part of the article explains the significance of phenology to agricultural production. "First of all", "for" and "can also be used" have four meanings, some are light and some are heavy, which highlights the significance of phenology to agriculture in four aspects.

Finally, once again highlight the "natural language" and take care of the first part of the text. The full text is clear, and the phenological knowledge introduced is easy to understand and impressive.

(2) The language is accurate, vivid and elegant. In the first paragraph, the phenological landscape of nature throughout the year is vividly written, which is a description method and shows readers a picture of the landscape of the four seasons.

"The Earth" and "Awakening" are anthropomorphic brushstrokes, and then two words with the same structure "Melting snow and ice, sprouting vegetation and letting a hundred flowers blossom" are combined into a long sentence, which describes the "Awakening" of the Earth in detail and brings people a piece of spring. The word "second" is used very elegantly.

Swallow "came back", and the lively and agile swallow image suddenly appeared in front of us. Yellow leaves "rustle" in the autumn wind, making people feel the scenery.

In addition, words such as "flying north and flying south", "in the field and grass", "disappearing", "dead grass" and "traveling in the snow" are elegant, concise, vivid and vivid, just like the focus plane. "Welcome winter with snow" is another anthropomorphic technique, which brings nature to life and prepares for another anthropomorphic "language of nature" below.

Finally, the author summed up the four seasons changes in this passage with four words: "year after year, cycle after cycle", which is extremely concise. In short, the beautiful words used by the author in the first paragraph are dizzying, and these beautiful words constitute a vivid picture, just like the beginning of a landscape prose.

In the second paragraph, the two groups of words "lush vegetation, migratory birds come and go" and "flowers and birds sing, grass grows and warblers fly" are extremely general, elegant and literary. What is more noticeable in this passage is the use of anthropomorphic techniques: "Apricot blossoms are blooming, as if nature were preaching to cultivate the land quickly", "Peach blossoms are blooming, as if suggesting to plant millet quickly", "Cuckoo begins to sing, and the working people know what it is singing ..." In these three sentences, "preaching", "hinting" and "singing" bring extremely rich phenology in nature to life, and it seems that there are people.

In addition, the language of the article is accurate and rigorous, which reflects the scientific nature of the explanation language. For example, the word "many" in the third paragraph "Many agricultural proverbs handed down from ancient times contain rich phenological knowledge" is limited in number, not generalized in scope and rigorous in wording.

When explaining phenological phenomena, we should first distinguish between "plants" and "animals", and then generalize "creatures", and the words are carefully scrutinized everywhere. When explaining the four factors that affect phenology, the exact figures are listed, and the exact examples are given and compared. For example, "the latitude of Dalian is about one degree south of Beijing, but in Dalian, the flowering period of forsythia suspensa and plum blossom is one week later than Beijing."

At the same time, it also uses the interpretation method of definition, such as "at the turn of autumn and winter, in a clear sky, the temperature at a certain height is inversely proportional to the low and high." This is called inversion layer. "

[Edit this paragraph] 2. Problem study 1. What is the explanation order of the four factors that determine the coming of phenology? What are the advantages of this arrangement? The author ranks the four factors that determine phenology according to the degree of influence, latitude has the greatest influence, followed by longitude, the difference between high and low, and the difference between ancient and modern times. In addition, latitude and longitude is the difference in position on the earth, the third factor.
