1. Write a 300-word composition about plants. Sugar maple forests are all over Canada.

It is also called sugar maple. Every year in late autumn, the golden wind is bleak, and the red maple leaves are as beautiful as the morning glow, and the colors are very beautiful, just like the red flowers in full bloom in spring. Canadians have a deep affection for maple leaves and regard maple as a national tree. Canada has the reputation of "Maple Country".

Sugar maple is one of the famous maple trees in the world 140. Sugar maple is a deciduous tree with a tall tree shape, some of which are more than 40 meters high and 40~ 100 cm in diameter.

Leaves alternate, serrated, palmate, usually three leaves, young trees five leaves. The trunk of sugar maple contains a lot of starch.

It turns into sucrose in the cold winter. After the second spring, the temperature rose, and sucrose became sweet and flowing juice.

At this time, people drill holes in the trees, and sugar liquid will flow out of the holes. The sugar content of the juice of sugar maple is 3~5%, and some of them can reach 10%.

A sugar maple with a tree age of 15 can produce about 2.5 kilograms of pure sugar a year, which is equivalent to 25 kilograms of sugar per mu, and can produce sugar continuously for more than 50 years. Because it has been planted for one year, it has benefited for many years and its output is stable, so it is known as "hard-core sugarcane".

Sugar made from this sap is called "maple sugar" and "maple sugar". Maple sugar contains about 85% sucrose, the rest is fructose, glucose and some special foreign substances, which has a unique flavor.

Its nutritional value can be compared with honey, and it has the effect of moistening lung and appetizing. Used as raw materials for making cakes, soft sweets and hard candies, with appropriate sweetness and delicious fragrance. Among many maple varieties in Canada 10, the most famous ones are sugar maple and black maple, which are the first-class raw materials for boiling syrup.

Quebec and Ontario in southeastern Canada are the two provinces with the most maple forests, where there are thousands of maple sugar farms. Every year from March, the Canadian people will happily celebrate the traditional Sugar Maple Festival and taste the sweet food presented by nature.

During the Maple Leaf Festival, the farms that produce maple sugar are all decorated. People wear festive costumes, sing and dance, and hold various activities to celebrate the harvest. A large number of tourists come to visit and share their joy.

On weekends, some farms provide maple syrup cakes and "toffee" for free (a cup of white spring snow is served and hot syrup is poured on it, which is full of color and flavor). The maple sugar festival usually lasts for more than a month.

Canada is the country that produces the most maple sugar in the world, with an annual output of about 32,000 tons. Besides food, Canada also exports a lot. The Canadian people revere the maple leaf. There is a red maple leaf in the center of Canada's rectangular flag with a white background.

The maple leaf has become a national symbol. 1860, when Prince Charles of England visited Canada, people decorated him with flaming maple leaves to welcome him.

In daily life in Canada, maple leaf patterns can be seen everywhere. The maple leaf is palmately 5-lobed, with a length of 13cm and a width slightly larger than the length. The three largest lobes have several prominent teeth, the base is heart-shaped, the upper part is medium green to dark green, and the lower part is hairy, which turns from yellow to orange or red in autumn.

The bark is grayish brown and smooth, and furrows and scales appear with the growth of tree age. The flowers are yellow-green, small and headless, hanging on slender stems, and open with tender leaves in spring, showing an open inflorescence.

The fruit has parallel wings and is 2.5 cm long. Height 30 meters, wide column, deciduous.

Usually, the white sugar, brown sugar and rock sugar we eat are mainly boiled with sugar cane and sugar beet. Cooking sugar with sap secreted by trees is a new thing in China.

In the forests of temperate regions of North America, there is a kind of sugar maple, commonly known as maple, which is the most famous in Canada. There are several varieties of sugar maple, such as sugar maple, silver maple and red maple. The first two kinds are famous for producing sugar.

Maple can be used as building material or equipment material, musical instrument material, sculpture material, etc. , can also be planted for ornamental purposes. Plants used for logging and fire.

Traditional Chinese medicine uses the root bark and branches in chicken feet, which are boiled in water when knee joint attacks. It is used in conjunction with ogapy (the author is not sure, this is provided by the data) during fracture; Has anti-inflammatory and detoxicating effects. Canadian maple (Acer truncatum) (also known as sugar maple) aggregates starch during the growing period.

With the melting of snow in spring, enzymes convert starch into sugar, and sugar is dissolved by water absorbed by roots, forming a faint sweetness. Maple juice contains water (about 97%), minerals, organic acids and maple flavors.

From the beginning of March, the sap will flow in the tree for 6-8 weeks to promote the growth of the tree. All trees produce juice, but maple has more and sweeter juice.

There are more than 65,438+02,000 maple sugar producers in Canada. Canada's maple sugar production accounts for 85% of the world, and the United States accounts for 15%.

Quebec (93.3%), Ontario (5.5%), New Brunswick (1. 1%) and Nova Scotia (0. 1%) are rich in maple sugar. According to Canadian data, the output of maple products in Canada in 2000 was 40 196 tons (88.4 million pounds), and the estimated agricultural output value was1515 million.

It is said that among the local 13 maple trees, only three kinds of maple trees, namely hard maple, black maple and red maple, can produce syrup. A big maple tree can collect 4 liters of sap every day.

According to the preparation method of the invention, about 65438+/-0 liters of maple syrup can be prepared per 40 liters of sap. Interestingly, according to the owner, only maple trees in North America can produce maple syrup.

Therefore, maple syrup has become a world-renowned specialty in Canada. From Quebec to Niagara Falls, the journey is 800 kilometers, which is the famous Maple Leaf Avenue in Canada.

Toronto, Kingston, Ottawa, Montreal and other big cities are all distributed on this Maple Avenue. The famous St. Lawrence River originates from the rippling Lake Ontario and runs parallel to Maple Leaf Avenue. More than 65,438+0,000 lakes, large and small, are scattered around Maple Leaf Avenue, forming a beautiful landscape with maple leaves blooming on the lakeside, riverside and roadside.

Bright maple leaves reflect blue sky and clear water, towns and villages, and the whole of Canada. No matter where you go,

2. Write a composition about plants in 300 words.

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.

3. Write a composition describing plants, with small petals of about 300 words, thin and strong branches, pale pink and fragrant all over. 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 the green in summer is deeper, that is green, 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, stand upright, stand upright, regardless of the wind and snow blowing. ...

This is why I love plum blossoms. I am 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.

4. I saw mimosa on the hillside of my hometown Jiulong Mountain before writing a composition of 300-word mimosa. According to parents, this plant is a perennial herb, but it is not as weak as other herbs.

The flowers of mimosa grow very special. He has a purple or pink flower ball, but it is not a flower, but a tidbit made up of many small flowers.

If you accidentally separate a small unit on the ball, you can see that each small unit has four split petals and four long nuclei. It turns out that every small unit is its flower. But why is this plant called mimosa? Oh, it turns out that when you gently touch him, his open pinnate compound leaves will be closed immediately, and then the whole leaf will hang down again, showing "shyness", but a reaction of the plant after being subjected to * * * and vibration.

Central reflex is biologically called nose movement, which is the result of the change of cell tension after mimosa is subjected to * * *. Judging from previous observations, there are still many gains today.

At least I understand why mimosa is called mimosa and how it is "shy". Mimosa is also very green, with green in it.

5. Write a composition on plants. Write a 300-word plant composition in the third grade (300 words in the third grade)

Beautiful peach blossoms

Every spring, I go to the park to see peach blossoms, but this year's peach blossoms are different from the past.

The peach blossoms are very beautiful this year. I remember that afternoon, the breeze blew and many petals fell under the tree. The breeze turned them into parachutes. In a blink of an eye, they blew up the petals falling under the tree, some fell on the green river, some fell on the roadside, and some even fell on other people's heads or strollers. From a distance, I thought the breeze was the air blown by others!

If you look closely, you will find that the petals in the peach blossom are rouge-colored, and there is a white border outside. Stamens golden yellow, slender, like gold thread.

Seeing such a beautiful peach blossom, I couldn't help leaning in to smell it. Ah, it smells delicious, so intoxicating!

Peach blossoms not only attracted me, but also attracted bees and butterflies to dance here.

This is my favorite peach blossom. I really like spring!

6. Describe and write the banyan tree in 300 words.

The beige trunk and dark green crown are the big banyan trees at the head of our village.

In spring, banyan trees spit out bright yellow leaves, and gradually the leaves change from light yellow to light green and dark green. The lush banyan tree attracts many birds to nest on it. Call a friend, a twittering bird, singing loudly in the tree. What a beautiful voice. There are countless roots hanging under the big banyan tree, which looks like grandpa's pale beard.

In summer, the sun is like the boss's fireball. The light was so strong that even the dog stopped barking and stuck out its long tongue to hide in the shade under the steps. At this time, the big banyan tree has become our favorite place to go. The big banyan tree blocked the strong sunshine for us and brought us a little coolness in summer. We are playing happily under the tree. The tireless chirping of cicadas in the tree will always attract countless naughty boys to climb the tree. They always like to catch a few cicadas and take them home, and listen to their cicadas in cages.

In autumn, banyan trees bear fruit, and when the wind blows, the fruit will make a "crash" sound. At this time, if we gently shake the trunk, the fruit will fall off. These fruits are small and beautiful, and the colors are green, red and yellow. These fruits bring us a lot of happiness. You see, those naughty boys picked up these fruits and stuffed them into their pockets, and then they started a "bean war", and everyone attacked them with fruits. Fruit hurts when it hits you, so everyone always hides while hitting it, for fear of becoming the target of fruit attack. At this time, the big banyan tree became a veritable "battlefield". We girls like to pick some beautiful fruits to take home and string them into chains with needles and thread. This little fruit bracelet looks beautiful on your hand.

This is the big banyan tree in our village. I love it.

This paper describes the different characteristics of the big banyan tree in the village head in spring, summer and autumn and the happiness it brings us, and expresses my love for the big banyan tree. The article is rigorous in structure, clear in organization and appropriate in details. The author also uses metaphor and personification in his description to make the sentence more vivid and worth reading.

7. The composition of plants 300 words I like a plant-sunflower. I named the sunflower "Sunflower".

Because it has a proud character, whenever everything grows, it is always the first to see the white of the sun, and it keeps staring at the sun. Where the sun is, it is there. It's really interesting. "Sunflower" was strong when it was a seedling. On its body, it spread bright green leaves as wide as Du's palm. Dewdrops rolled on the leaves and shone like silver beads in the sun.

Sunlight and rain make "sunflower" grow day by day. Its pale green waist is quite thick, proudly tall and straight, like a sentry on the grassland. Slowly, the sunflower finally appeared in front of the road wearing a green hat. The golden petals turned around along the hat, and the little head was tightly buckled by the hat and refused to show his face! "Sunflower" opened its eyes and saw the warm sunshine smiling at it, and the breeze and drizzle were dressing it up. It showed a beautiful big face of Zhang Yuanyuan with joy.

Sunflower is still a sensible child. Nature has given it everything, and it should also be dedicated to people. It puts rich fruits on its face, and the dense seeds are extremely full.

What lovely sunshine flowers.

8. Write a cactus with more than 300 words of plant metaphor. Alas, this is really a strange plant with tenacious vitality! The cactus in potted plants, its tough character is surprising enough.

It doesn't care if there is water, it's hot and cold. Its emerald-like palm-shaped stems covered with hard thorns keep stretching upwards, and like a pyramid, a small piece grows on a "green palm", overlapping each other and standing upright in this posture. No matter how dry the weather is, other potted plants bow their heads, but they are always full of vitality and go straight to the sky.

As for the living environment, it never seems to be taken seriously. It seems to be shouting happily all its life: "This place is very good, just look at me flourishing here!" It is full of thorns, and no wild animal can invade it; Don't try to bite any pests. A green cactus broke off and fell to the ground. Do you think it is dead? Don't! It uses its own nutrients to cultivate another young cactus, which is really called "rooting"! Such a brave and thorny plant, who would have thought of it, but they have bright flowers! Some cactus flowers are beautiful.

The national flowers of various countries include plum blossom, lotus, rose and lily. You can imagine that in Mexico, a distant country with a large number of riot heroes in history, the national flower is cactus! Throughout the ages, people have been praising the firmness of pine and cypress, the integrity of plum and bamboo, the arrogance of lotus, and the brave struggle of hedgehog against the west wind ... I think cactus is especially worthy of praise. Sure enough, I saw a poem by Nie Luda, a Chilean poet, dedicated to praising cacti on the coast.

Some fragments read: My cactus, you have many thorns. You are the brave enemy of desert and dry wind. ..................................................................................................................................................................................

In addition, you solemnly raise your erect head covered with thorns ... such a strange poem is very suitable for describing such a stubborn plant. Cactus has such magical vitality that people with general plant knowledge know that it originally grew in the desert, where life was difficult, hot and cold, sand and stones flying, and drought and violence, and cactus was exercised day and night for thousands of years. After such a long time of "natural selection", cactus has finally cultivated such a stubborn character and outstanding style that dwarfs ordinary plants, otherwise.

In the hometown of cactus, such as Mexico, wild cactus can grow to a height of one or two feet, just like a big tree. In China, Yunnan and Hainan Island of Guangdong, cactus is also magical in the wild.

I have been to some national defense outpost islands south of Hainan Island, where cactus grows like a mound on the beach. It can grow anywhere, even in the sand between rocks and the rotten wood of stumps. This is a yellow-brown, palm-shaped cactus with sharp needles like steel needles and delicious fruit the size of loquat, which will turn purple when it matures.

I can't help thinking of Nie Luda's poems when I see them so full of youthful vitality where they are immersed in seawater. This is exactly the kind of "cactus on the coast" praised by the poet.

Only the strong human beings can conquer these plants, and this is the soldiers of our national defense outpost! For example, I have been to an island, Dongzhouzhou, and another island, like the eyes of Hainan Island, protrudes forward and stands in the vast waves of the South China Sea. On the beach of this island, cacti are densely covered.

But according to the soldiers guarding the island, I don't know how many cacti have been hoed off now compared with when I first landed. Ten years ago, they came to this dark green island from the icy northeast. At that time, where were the fields, houses, pastures and roads on this island? Cactus! Cactus are everywhere! At the beginning, this island crossing was deserted.

Even today, outside the beach where you can land, you can still vaguely see the style of a tropical island, which maintains its original style in the rocky coastal areas. In the vast blue ocean, the waves keep coming in, hitting the rocks, making a roar of heaven and earth and splashing white foam.

Sea crabs walk through the cracks in the rocks, which are densely covered with barnacles and oysters, and sea cucumbers squirm in the clear sea water, spitting blue and white mucus. In the sky, the rock eagle is gliding.

What a vast and empty scene! 10 years ago, the whole island was so primitive. The Japanese invaders once occupied this small island. When they failed, they filled the well, blew up the dock and left rusty cannons.

The whole island is occupied by cacti and weeds that are more than one person tall. So when the people's soldiers first landed on this island, it was like landing on a primitive desert island.

So man and nature launched a fierce struggle. The army that once fought bloody battles along the Songhua River and pursued in the cold of MINUS 40 degrees has now come to a desert island where rocks and weeds smoke.

What they have experienced may be much more difficult than what cactus has experienced for thousands of generations. First, they want to open up the grass and set up tents, surrounded by snakes and centipedes.

At that time, they were about to meet several snakes after a short walk. The first thing to do when you get up every morning is to pat the poisonous insects on your clothes.

In the hot summer in the south, the mercury column of the thermometer rises to 37 degrees. You know, in geography books, 33 degrees Celsius is called "extremely hot".

In this climate, hard work goes without saying, and the most difficult thing is water. Every drop of water that is more precious than gold must be shipped from Hainan Island. Every four people use a basin of water every day, cooking, cooking, washing and bathing, all by it! Under the scorching sun, many soldiers have cracked their lips, but they are still sending water to each other.

At that time, it is conceivable that letting water need selfless spirit more than blood transfusion! The hut was put up, but we met again.

9. Composition describing plants If you write a 300-word composition about plants, cactus is made of better materials and can be changed.

\4\3\4\3\4\3\4\3 There is a very humble cactus on my balcony. \4\3\4\3 The cactus's body is like a piece of jade and a cute little hedgehog.

It is covered with thorns like steel needles. Don't underestimate these thorns. This is the weapon it uses to defend itself and fight back! I was stabbed by it, and my mother was stabbed by it, which was very painful. My mother tried to throw it away many times, but I refused because I had a special feeling for it. I like cactus.

\4\3\4\3 Spring came, everything woke up, and a small cactus appeared on the cactus "mother". It looks so soft and gentle, as if a gust of wind could blow it away. And its "mother" is afraid that her children will be "bullied" by the cold wind in early spring, and always blocks the cold wind with her body, but the cactus always climbs up. Finally, with the encouragement of Grandpa Chun Lei and the help of Sister Chun Yu, the cactus overcame many difficulties and grew up.

\4\3\4\3 In late spring and early summer, the cactus sprouted. Strangely, the cactus blooms in "order", and always two flowers bloom together, like a pair of twin sisters and a bow tied on the little girl's head. Cactus flowers are white and fragrant, like a beautiful fairy wearing a white dress, dancing gracefully on the jade stage, and emitting intoxicating fragrance from the dress.

\4\3\4\3 Autumn, the harvest season, the cactus has grown up, and its use can be much more! You can cut into pieces and soak them in cool and delicious tea to quench your thirst. Edible, nutritious, and can also be used as a bonsai ... one after another, but the most surprising thing is that it can be boiled into medicine to treat diseases.

\4\3\4\3 People love magnificent peonies, autumn chrysanthemums in various shapes and sweet-scented osmanthus in miles ... but I only love cactus, not only because of its appearance, but also because of its quality.

I have seen mimosa on the hillside of my hometown Jiulong Mountain before. According to parents, this plant is a perennial herb, but it is not as weak as other herbs.

Mimosa is also very green, with green in it.
