Botanical Garden is located in the western suburbs of Beijing, near Xiangshan, where there are trees everywhere and the air is fresh. Entering the gate, we came to Wansheng Garden, a tropical botanical garden.
This is a huge steel circular building with a glass curtain wall outside, so the lighting is good. There are many tropical plants in the hall, including coconut, palm, betel nut … and a huge fountain.
Dad said to walk clockwise, so we came to a house, where many great cacti were planted. We really want to touch them, but we are afraid of stabbing our hands, so we keep looking forward. In front of us are simulated tropical rainforests, tall shrubs and a wide variety of strange tree species, most of which are hung with small signs for us to learn and understand. Suddenly, I found a dinosaur, and I was shocked. Take a closer look. It turned out to be a model.
Walking through a small bridge, the waterfall in front of you, the water flows down from the bottom of the bridge, as if you were in a paradise. It must be comfortable to rest here at night. On the first floor, I came to the tropical desert plant area. The tall cactus, round cactus and hot heat wave made people feel like they were really in the desert.
Rushing forward, we came to the central hall, which is still cool and fresh. Dad took many photos of me, rested for a few minutes, and then we came out. Along the plastic road in the Botanical Garden, we visited the Butterfly Museum. There are so many butterfly specimens, which really opened my eyes! Further on is the lotus pond. The giant lotus leaf is like a giant umbrella. Fish are swimming under the lotus leaf. The blooming lotus is so bright. I asked my father to take some photos to combine me with the beautiful scenery, hehe.
Finally tired, we decided to go home, today's harvest is great.
2. Write a 400-word essay about plants in nature. There are many kinds of plants in nature. Let me introduce some wonderful plants to you!
Dancing grass, never heard of it. This is a kind of dancing grass. When people talk or sing to it, the small leaves will dance left and right, just like the grass will dance when it hears your voice, so people call it dancing grass.
Dancing grass belongs to Leguminosae, which is produced in some provinces and regions of South China. Now many botanical gardens have planted dancing grass, which has attracted much attention as a kind of moving pet.
Nepenthes often grows horizontally in nature, with complex leaf structure, petiole, leaf body and tendrils, and the tail of tendrils expands and folds back to form a bottle shape, which can prey on insects. Nepenthes have racemes and small green or purple flowers. The bottle-shaped body at the top of Nepenthes leaves is a tool for preying on insects. The opening edge and cap of the bottle can secrete honey and attract insects. The bottle mouth is smooth, the insects slide into the bottle and are submerged by the liquid secreted by the bottom of the bottle, and the nutrients of the insects are decomposed and gradually digested and absorbed.
Plants depend on chlorophyll to make nutrients under light, but there are also parasitic plants, and rattan is one of them. Rattan and morning glory belong to Convolvulaceae. Due to parasitic growth, the leaves have degenerated into small scales, with no chlorophyll, all white. Twisted plants act as hosts for providing nutrition. The stamens and pistils in the closed corolla of Caulis Sargentodoxae keep the characteristics of convolvulaceae, and bear seeds after flowering, which can be used as medicine, namely Semen Cuscutae.
If you are not satisfied, you can have another one.
3. Make friends with plants in nature and write a composition. I am a grass. Although I don't have the beautiful clothes and graceful figure of Sister Butterfly, as a member of nature, I adorn this beautiful world of flowers and flowers. I am very happy! Spring has come, and Miss Chun has awakened all living things with her beautiful singing, including me, an unknown grass.
I struggled to break away from the embrace of Mother Earth, quietly poked my head out, enjoyed the first sunshine after leaving the darkness, greedily sucked the fresh air and sprinkled the first sunshine of spring to the world. Summer is coming, which is a good season for us to grow up.
But the weather is like a child's face, crying, laughing and making noise. No, the rainstorm is coming again! Sister raindrops as big as rice grains can be merciless. She keeps hitting us on the head, often beating us black and blue! The rain has stopped. After the baptism of heavy rain, we seem to grow taller and more lovely.
Look, some chubby birds are learning to fly. They jumped up and down on me, but I didn't feel any pain. From a distance, a few little guys rolled on the green carpet like cotton candy! Look, those children are playing happily on the soft grass. A naughty boy shouted: "Come on, lying on the grass is very comfortable, and you can smell the smell of the soil!" " "I heard that, I am really happy to the extreme, just like plugging in wings and flying into the sky.
In late autumn, I gradually became yellow and weak. But I always want to do something. It happened that the little beetle brothers became my first choice. I held them in my arms and built a happy nest for them with my warm body temperature.
Hey, look at them sleeping soundly and drooling. The cold winter has come quietly, the terminal of my life has arrived, and the years have passed mercilessly. I have no youthful time full of youthful vitality, only the old and weak.
But I believe that "the boundless grass on the grassland comes and goes with the seasons". Wildfire never completely devoured them, and they grew taller again in the spring breeze. "
In the spring of next year, countless grasses spread their indomitable spirit on the earth and sent back letters.
4. The inspiration of a 300-word plant composition of Mimosa in Nature.
No matter how famous the teacher is in the world, he is not as powerful as the "teacher" in nature. He gave us a lot of important enlightenment from many things. Let's talk about the enlightenment that mimosa brought to me first!
Once, I bought a pot of mimosa to see if it was really "shy". I gently touched its leaves with my fingers first, but I didn't expect it to close the leaves at once. I touched its stem again and it bent down. I looked at it strangely and excitedly. Is it really "shameful"? I want to know the reason behind this phenomenon. So, I ask everywhere, ask dad, ask mom …
Of course, I didn't give up my efforts myself. I finally understand! I found on the Internet that there is an enlarged organ called "leaf pillow" at the base of the petiole of mimosa, and there are many parenchyma cells in the leaf pillow, which is very sensitive to external factors. Once it touches the leaf, * * * will be transmitted to the leaf pillow, and then the cell fluid in parenchyma cells will begin to flow to the intercellular space, thus reducing the expansion ability of cells. When the pressure between cells in the lower part of the occipital lobe decreases, the lobe will automatically close.
Mimosa not only made me understand the scientific knowledge behind some scientific phenomena, but also gave me a more important revelation: if we imitate the characteristics of Mimosa, we can make a machine, hang it on our body every day, and meet all kinds of storms and threats, just like the leaves of Mimosa, we can wrap people up, so that people will not be injured!
5. Seek a natural plant. Nature's plum petals are small, the branches are thin and strong, pale pink, and the fragrance wraps the whole body.
This is a flower that blooms proudly in winter. This is a flower that looks whiter in the snow. It is a flower that cannot be crushed by snowflakes. Yes, it is plum blossom.
Flowers standing proudly in the winter snow. May, spring and summer seasons.
The sun is shining and colorful. Just after the defeat of Jasminum nudiflorum and Magnolia grandiflora, small buds, strings of pink peach blossoms and lush green grass appeared in the Chinese rose. All this is just as people say, yes, I agree, spring is indeed the season when everything recovers.
She gives people the feeling of light green, faint green, endless green, and in summer, the green is deeper, that is green, and the green is deeper. However, winter, the most lifeless season of the four seasons, gives people the feeling that it is a vast expanse of whiteness, and the snow is overwhelming and sweeping, which can only add a little pine and cypress to this withered winter, and at this time it is covered with thick snow.
Those flowers in summer are just dead branches and rotten leaves at this time. There is no longer the charm, wealth and air of the past, and their only twigs are too tired to breathe under the weight of snow, so they can only wait for death sadly.
At this time, in the snow all over the sky, in the lament of everything, plum blossoms appeared and stood proudly in the snow. Her tall and thin branches are not affected by the snow at all.
Snow proud first frost. In full bloom in the snow, full of pride, standing upright, standing upright, regardless of the wind and snow blowing ... this is why I love plum blossoms, strong and unyielding.
Although it is too cold to go out in winter, plum blossoms bloom in the snow. The spirit symbolized by this small flower is far more noble than the colorful roses, Chinese rose and peony in that summer. Look at that plum blossom. Seemingly pure white snow, only a pool of stains is left after the snow melts, which is flashy. And plum blossom, she is really pure white, sometimes with a little pink, she left a fragrance that seems to be absent.
Her simplicity and elegance are beyond the reach of ordinary people. Look at the plum blossoms standing proudly and blooming in the snow. Don't you feel her beauty at all? Didn't you suddenly see a plum blossom standing in front of you in the vast snow, and you wouldn't be infected by her indomitable spirit of not being afraid of cold and frost? Have you ever thought that she is somewhat similar to the indomitable spirit of the Red Army soldiers? Don't you think this notice covered with heavy snow really symbolizes our revolutionary soldiers, their indomitable spirit, their courage to fight and their will quality? People praise the peony because of its wealth, the lotus because it emerges from the mud without being stained, and I praise the plum because of her indomitable spirit, which also symbolizes those who are more and more brave in the face of difficulties! Nature is beautiful. Lush, evergreen trees and colorful flowers decorate nature and people's lives with their colors, shapes, shapes and functions, creating a beautiful and colorful environment for us and providing all kinds of indispensable resources for mankind.
Imagine yourself as a plant or animal in nature. If I were a tree, write a 500-word composition.
If I were a tree, I would grow taller and taller with the passage of time, and finally grow into a towering tree. My slender branches are covered with dense branches and leaves. Great changes have taken place in my growth, and the green lawn in my eyes has become a tall building; Factories, streets It is also the waste water, waste gas and waste residue discharged by this factory that makes Mother Earth suffer from various skin diseases, and also makes Mother Earth wander in disillusionment, which is greatly threatened.
Spring has come. This is a sunny season. I want to absorb all the waste gas in the world, release oxygen and let people live in a pollution-free environment. In a beautiful land, everyone can breathe fresh air and grow up healthily and happily.
Summer is coming, it is a green season. I try my best to stretch my thick branches and leaves like an iron ball to block the fiery sun and let people enjoy the cool and chat under my thick branches and leaves. Autumn is coming. This is a hot season. I became the children's bosom friends. They are enjoying themselves under my branches. I shook the branches and made a rustling sound ... laughter was also immersed in our joy. At this time, Xifeng also came to join in the fun. "She" is like a flying butterfly, blowing down my yellow tree.
Winter is coming. This is a cold season. It turns out that my withered branches and trees have slowly fallen off and built a "small palace" where insects live a happy and harmonious life ... It is also at this time that I try my best to absorb nutrition, make full preparations for the new year's work and make greater contributions to mankind.
In this year after year of work, I have become good friends with human beings, but human desires have made Mother Earth more and more riddled with holes. As the lungs of the earth, "we" will do our duty to return the clear water and blue sky to our lives. Let Mother Earth be healthier and more beautiful, let people understand the current predicament, and care more for our Mother Earth!
7.2 Composition describing plants or nature 1. The composition of nature:
I love nature because it is full of vitality; I love nature, because it is like a beautiful poem and colorful fairy tales. Listen, nature is calling us!
"Blue sky and white clouds are floating, the sun smiles slightly, wild flowers nod, the scenery is really beautiful, the scenery of nature is really beautiful …" The children are practicing singing "Good Spring" by German writer Mendelssohn. They play and sing on the green carpet prepared by nature for them. Hearing this, Liu Yang proudly looked in the mirror, combed her flowing hair and tied many green ribbons. Show flowers and plants the colorful figure of "She" Ona.
"I know, I know." Cicada is screaming excitedly on the branch, as if to sing with the newborn frog-tadpole, but the tadpole can't respond, because the tadpole is sweating for his mother! But cicada can't help tadpoles. It wants to show the world its beautiful singing voice. Finally, the tadpole found her mother, and at the same time, she was fascinated by the place where her mother hung around-on the crystal clear river, the floating lotus flowers danced like pink girls under the breeze, as if to tell people that they were the best dancers in the world, and they were even more beautiful and dazzling against the green round skirt with glittering pearls, as if watching them.
"sasha vujacic, sasha vujacic ..." Ginkgo biloba leaves, like a small golden fan, blew away the heat in summer and brought the coolness in autumn. Accompanied by the rustling sound, there are three singers who live in seclusion under the tree-crickets, slugs and oil hyacinthus orientalis, one after another, a large piece, far and near, forming a grand natural symphony. It makes people uncomfortable.
"Woo-hoo ~ ~ Woo-hoo ~" Accompanied by the howling north wind, there was a rush of snow. It's white everywhere in the morning, and thousands of trees are pear blossoms. The straight cement road has been paved with a long white carpet, which extends to the distance and to the place where the snow meets the sky. It is so pure and crystal clear that I can't bear to step on it, so as not to damage this rare silvery white carpet given to us by nature. Children are also laughing and playing on this natural carpet, having snowball fights, skiing and skating on the ice in the park ... Look-there are a group of lovely children chasing them in the endless snow! A child fell and was not afraid, because the silver carpet was soft. The child rolled in the soft snow and stood up. The child is very happy and makes adults laugh, because the child has become a real "snowman". I watched them so free and happy! Makes me want to join their game.
I love nature, its beautiful spring scenery, its cicadas, its rolling wheat waves, its white clothes ... it is like four flowing pictures, slowly spreading and blooming in front of us! ! ! I love nature!
Second, the composition of plants:
Sunflower
There are many kinds of flowers in the world, such as Magnolia grandiflora, Chinese rose, rose, plum blossom, chrysanthemum, Clivia, camellia and so on. However, the flower with the most flowers and the richest colors belongs to the sunflower. As the saying goes, "good flowers don't bloom often." Sunflower is also a good flower, including red, yellow, white, purple, crimson and orange ... Sunflower petals are single-layered, shaped like plum blossoms, with a red core and yellow spots on black filaments. Sunflower stems are long and thin, soft and curved. It has thin branches, dense leaves and many flowers.
Sunflowers only bloom when they see the sun. Every day when the sun rises slowly from the east, sunflowers are scrambling to open their smiles. When the breeze blows away, the sunflower "shakes its head", as if reading a poem and nodding to pedestrians. The flower bones of sunflowers are red and the shape is the size of soybeans. Unlike other flower bones, they are short and round.
Sunflower seeds are surrounded by several small leaves. Flower seeds are as big as sesame seeds. When the seeds of small flowers are ripe, they are scattered in Grandpa Earth's arms. After being nourished by sunshine and rain, they can grow more beautiful sunflowers in the second year.
Sunflowers are full of vitality. She sucks the nectar that Grandma Blue Sky gave her and greedily absorbs the nutrition of Grandpa Earth. Sunflowers thrive under the care of Grandpa Earth and Grandma Blue Sky, making the motherland more beautiful and adding icing on the cake to the beautiful nature.
Sunflowers at night are like a child playing all day, tired and gratified to enter a sweet dream.
Morning glory is also a good flower. It blooms early and fails late. It and sunflower seem to be a pair of good sisters. They agreed to open up together, enter the sweet dream country together, not early or early, and decorate this beautiful nature together. They give themselves selflessly and never ask for the return of the motherland or the appreciation of the people.
Although sunflower is not as noble as rose, as fragrant as chrysanthemum, as pure and elegant as Magnolia grandiflora and as fragrant as plum blossom, it has the spirit of selfless dedication.
I love sunflower, its tenacious and vigorous vitality, and I love its selfless dedication.
8. Write a composition with the theme of "approaching nature" to understand "man and nature" and look at the contradiction between man and nature from the perspective of sustainable development.
Because the topic is big, you need to work hard on your conception and choose a delicate angle. Remember the color of the sky? I tried again and again to find those little memories in my mind: the blue sky in late autumn was spotless and crystal clear; The sky is like the plump wings of a big bird, covered with white feathery clouds, and there are some blue abyss between the white clouds, from which the golden sun comes out. As soon as it saw the earth, it changed everything on it. The space on the horizon is crimson. It turns pale gold at a higher place, then yellow, then blue, and then to the zenith, which is a clear and vivid blue ... I can't tell whether this is a memory or a description by a literary master. The sky in front of me has no similar feeling.
Looking up in the morning, the buildings standing not far away are faintly visible in the smog-shrouded city, and there are several chimneys smoking leisurely on both sides. The pungent smell is everywhere in the air, which makes people breathless. Unconsciously, our living environment has become so bad, and the air quality we live on is so bad! When I first arrived in Beijing, my friend told me that standing on the top of Wanshou Mountain in the Summer Palace, I could see the scenery in the city. Now that I think about it, this is undoubtedly a beautiful legend.
How did all this happen? Who did all this? Industrial waste gas, automobile waste gas, domestic waste gas ... in just over ten years, we have wiped out the blue sky with our own hands! If nature has a court, what should we do? Nature can't judge, but it doesn't mean we can get away with it. In history, the "smog incident" in London caused more than 4,000 deaths in four days, and countless people suffered from bronchitis, coronary heart disease, tuberculosis and heart failure. The large-scale influenza outbreak in Beijing since winter is a warning to nature. We will never see the blue sky again, and we will lose not only our broad vision, but also our health.
Can people with conscience be indifferent to this? Blue sky and white clouds are a gift from nature. But greedy people don't cherish them and make a clear and transparent sky smoky, which really deserves the title of the smartest "advanced animal" on earth. What's worse, it goes against the mission of nature managers. Tracing back to the source, coveting comfort is the selfish nature of human beings. For their own comfort and convenience, they ignore the natural environment and other creatures, leading to the extinction of a large number of biological species. As described by a scholar, wherever human civilization goes, it leaves a wasteland.
From the analysis of pollution sources, the main air pollutant in the past was soot. With the rapid development of automobile industry, automobile exhaust pollution has become very prominent. The appearance of automobile is a symbol of modern civilization that contemporary people can be proud of, and the appearance of this industrial civilization has brought extremely uncivilized influence.
Is this not a great mockery of modern civilization? Serious air pollution woke up Beijingers, and people made up their minds to "wipe the sky" and give me back the blue sky. This is hope.
However, maybe we should reflect more. With the rapid development of urban construction, trams and old hovercraft have long since been retired, but now people can't help but find that the obsolete vehicles are just good for environmental protection, so people are developing to change fuel vehicles into gas vehicles. What does this repetition tell us? Different people have different opinions.
But this is related to the quick success and instant benefit of mankind. We might as well think about it and have a look. The appearance of air conditioning brings us warmth and coolness, but it emits a lot of harmful substances such as fluorine. Excessive abuse of chemical fertilizers has brought us a bumper harvest, which has also led to the hardening of the land and the variation of vegetables; The spread wings of the plane have brought us convenience in traffic, but it has caused serious air pollution ... Almost all modern civilizations are traps and caused many modern diseases.
When spiritual human beings create modern civilization, have they considered what side effects its appearance will bring? Yes, society will always develop, but any economic development must not be at the expense of the environment, otherwise we will create a "time bomb" to destroy ourselves. Remember the color of the sky? If you forget, you might as well take a look and think about it.
Give me back the blue sky, not just a dream. We have no retreat, only one last fight.
Humans should have a little sense of responsibility, clean up their polluted sky again, and let our future generations see the endless blue sky again. = = = = = = = = = = Beautiful nature, let's take our children into touching colors together. I remember a long time ago, I read such a short story: my aunt in kindergarten was holding a red apple in her hand and asked her children, children, can anyone tell me where the apple came from? The children's answers are similar: mom bought it; I bought it from the supermarket; It was sent by someone else ... I couldn't help but be surprised to see such an answer.
Why didn't anyone answer: apples grow from apple trees; Apples are picked from orchards ... Our children are really getting farther and farther away from nature. What they see in their eyes and hear in their ears are all more and more commercialized information. Children in cities spend most of their play time in art classes, calligraphy classes, piano classes, violin classes, composition writing classes and English classes. Their young minds were influenced by literature and art prematurely.
What kind of children are we going to raise? All-round talents, good quality, rich connotation and excellent quality ... but are these enough? I think we don't want our children to know animals and plants that are just solidified into gestures and lifeless images and specimens seen in books and showrooms, and we don't want our children to come into contact with only a few animals kept in zoos, do we? Let the children go into nature! Feel the sweetness of earth and grass, listen to the chirping of insects and birds, watch bees flying, butterflies dancing and insects crawling, and explore and enjoy the mysteries of nature with a pure and curious heart.
9. Write down what you see, think and think about a plant in nature. Write a composition about grass.
Grass is a symbol of vitality. Full of thick green grass, it is a model of tenacious vitality. Grass can be seen everywhere on the roadside, on the beach and under the roof eaves. The blazing sun can't bake it through, nor can the cold of ice bones break it. A spring rain hit, it held its head high, straightened its chest and emerged from the ground.
When spring returns to the earth, everything recovers, and it is another year of grass and spring flowers. On the Yuan Ye, the grass has changed into green clothes and is full of vitality.
I love grass, and I love her tenacious vitality. Whether it is barren wasteland or fertile soil, as long as the seeds of grass fall, she will sprout tenaciously and unconsciously show her pointed little head. In early spring, before the snow melted, I walked on the road and inadvertently saw the grass under the snow, so green and tenacious. Except this bag of grass, there is no green around, so the green grass has become the messenger of spring.
The snow gradually melted, and another batch of grass stood up, so green and fresh. Ah, the grass has turned green. "The rain in the sky is crisp, but the grass color is far away." The misty scenery is really beautiful After that, the birds are singing and the flowers are blooming.
Grass's life is unremarkable. No one needs watering or fertilizing. As long as there is a handful of soil and a beam of sunshine, it can thrive.
In summer, the vitality of grass is getting stronger and stronger, enjoying the joy of grass growing and warblers flying. However, the poisonous sun in summer is somewhat ruthless, and I can't wait to scorch the green; The wind like a heat wave is also cruel, and I want to uproot the grass, but the grass is still very strong, as if nothing had happened. The cruel summer finally brought a storm. In the storm, sharp-edged raindrops stung the grass desperately, making them stagger. After the heavy rain, some grass bent to the waist, others crawled on the ground and had no strength. However, they didn't and won't give up. Under the call of the bright sunshine, they quickly stood up one by one, and the green grass with raindrops was more vigorous and fresh.
A few months later, autumn arrived. The leaves and crops on the trees gradually turn yellow, and many lives seem to have come to an end. However, even at the foot of fallen leaves, there are some green grass, which may be the last touch of green in a year. Some grass turned yellow, but it didn't die. They are still standing in the cold wind, like immortal soldiers. They greeted the arrival of winter with fearless spirit. The trees are bare and snowflakes are falling. Look at the foot of the tree, and you can see the traces of green. The grass smiled: If winter comes, can spring be far behind?
As Gerry sang, there is no fragrance of flowers, no height of trees ... As the ancient poetry recited, wildfire never devoured them, and they grew tall again in the spring breeze. Grass is a group of tenacious and lovely children, who always hold their heads high and extend their green arms.
