Composition of plants in the fourth grade of primary school

In our daily life, everyone must have been exposed to composition. Composition is a narrative way in which people express the relevant knowledge, experience and thoughts stored in memory in written form. How to write a good composition? The following are eight essays on plants collected by me in the fourth grade of primary school for reference only. I hope I can help you.

There is a strange plant in my home. Its name is cactus. Do you know how the cactus got its name? To tell you the truth: because it looks like a human palm, people call it cactus!

Cactus is green when it first grows, and its body is covered with many small thorns. These thorns feel soft. When the breeze blows, the prickles of cactus dance with the wind. How beautiful!

In a short time, the cactus becomes emerald green, which makes people look so dazzling, so comfortable and so fresh. The small soft thorns on its body have also hardened, just like steel needles. After a while, it grew another flower bone. Slowly, it grew bigger and bigger, and finally a big red flower appeared, which looked really beautiful! According to my grandmother, it is not easy for cactus to bloom, because cactus only blooms once in many years.

The appearance of cactus is not very beautiful, but every piece of cactus is a treasure!

Cactus is rich in nutrients, such as potassium, calcium, zinc, phospholipids, vitamins and cellulose. According to Compendium of Materia Medica, cactus has the effects of promoting qi and blood circulation, clearing away heat and toxic materials, relieving swelling and pain, invigorating spleen and stopping diarrhea, calming the nerves and inducing diuresis.

My favorite is cactus flower. Have you seen it? Grandma said cactus flowers have many colors, including red, white, purple and orange. These flowers can not only beautify the environment around us, but also make the indoor air fresher. When these flowers dry up, you will see their fresh flesh, which makes you want to eat, but you should be careful. It's boring if the thorns on it prick you!

Friends, after listening to my sermon, you must really want to raise a cactus, right? Ok, go and raise a pot!

There are three camphor trees and a pine tree in front of my house. There are many saplings under the tree. I think they must be their children!

Cinnamomum camphora is tall and lush, standing in front of the door like a patron saint. Compared with it, pine trees are much smaller, which is not surprising, because pine trees are much younger than camphor trees. From generation to generation, camphor tree is still the aunt of a pine tree.

One day, I suddenly found a lot of bugs on the branches of pine trees. I looked at the camphor tree again. There were no bugs on it. This phenomenon makes me very confused. Not long ago, I found the answer from "100,000 Why". It turns out that the tree itself has a fragrance, which is the bane of insects, so insects dare not climb the camphor tree. The mothballs we use now are made from the bark of camphor trees. Placing mothballs in the wardrobe can protect the "safety" of clothes.

It seems that plants are really good friends of mankind! I decided to plant this tree in my yard and let it spread all over the world clean and fresh, right?



I had a strange dream.

Dreaming that fish grow on trees,

Waiting for you to pick it like a green pepper;

I had a strange dream,

Dreaming that peppers were swimming in the water,

Like little red fish;

I had a strange dream,

Dreaming that swallows have four legs,

Running in the forest;

I had a strange dream,

I dreamed that rabbits had a pair of wings.

Fly freely in the sky;

I had a strange dream,

I dreamed that eggplant floated in the sky like a balloon.

Free play.

This summer vacation, my family traveled to Hainan and visited Xinglong Tropical Botanical Garden.

Walking into Xinglong Tropical Botanical Garden, I saw the trees in the park are tall, lush and lush. There are all kinds of exotic flowers, herbs and trees everywhere, including herbs, cocoa, foxtail coconuts, tourist bananas, and the legendary "blood seal throat". When the tour guide introduced the rubber tree to us, grandma said with emotion: "In the past, young intellectuals went to the countryside to open up wasteland, and they had to get up at one or two in the morning to cut rubber, and then they had to collect rubber at eight or nine in the morning. This work is very hard. Rubber tree glue has great uses, which can be made into automobile tires, rubber shoes and so on. How hard life was in the past. Now the country is rich and strong, the economy is developed, everything is modern and high-tech, and people's lives have become happy and beautiful. "

After listening to my grandmother's words, I thought: I must cherish the beautiful life now, study hard and serve the motherland with what I have learned in the future.

Can you hear the sound of flowers blooming? Can you hear the grass growing? I tell you, I can hear you! What a beautiful voice! I often listen to this sweet voice in my field in Xiaotian.

In the morning, the sun shone through the window and scattered small gold threads all over the floor. A Clivia looks very comfortable when bathed in this holy light. I put my ear on the petals and vaguely heard the sound of "hissing" and "rustling", like a sand hammer swinging rhythmically.

At noon, the burning sun hangs in the blue sky, surrounded by several white clouds. Sunflowers sway with the wind, but always face the sun. I think, in a few months, it will grow "pimples" all over its face. I watched the sunflower carefully, and I heard the buzzing of bees, as if a conductor was busy conducting.

At night, one or two stars twinkle in the sky, like a naughty child poking a hole in a black cloth. Cordate telosma not only doesn't sleep, but also dresses herself up beautifully. A gust of wind blew across the lawn, and the grass banged up like a flute playing a lullaby.

You see, flowers and plants also have music. Let's listen to more and more beautiful music in nature!

Today, my parents took me to the botanical garden.

Baoding Botanical Garden is located in the north of Baoding, with a total area of 1 10 hectare. The whole garden is dominated by plant landscaping, which mainly displays various plant postures and natural wild interests of various plants. So far, more than 500 kinds of plants have been introduced.

Due north of the Autumn Garden is Yao Yuan, covering an area of 65,438 0.38 mu, including 59 mu of water. It forms a unified water system with Zhuyuan water system, showing Tang Yao culture, and is also the largest water system area of Zhuyuan Rock Garden in Hebei Province at present. There are 9 bridges in the park, including waterside pavilions, wooden pavilions, wooden platforms, flower stands and other architectural sketches, as well as Yao Mu Cave and Ancestor Cave, in which there are murals representing the myths and legends of China. There is a arboretum on the east side of the cave, including a bamboo garden, a gold and silver garden, a Gui Huayuan and a rose garden. ...

We visited the north of the botanical garden by the way. I will introduce the botanical garden to you. I hope you have time to go there and get some fresh air.

There is a botanical garden near our community, where the four seasons are beautiful.

In spring, young trees germinate, flowers become small flowers, grass turns green, and birds return to their original homes.

Summer has come, the young shoots of small trees have turned into big green leaves, the grass has become greener and the flowers have become more gorgeous! In the evening, Guoguo sang in the grass and held a small concert.

Autumn is coming, some trees are covered with fruits, crushing the branches, and some leaves are yellow and withered. It is falling piece by piece. We are very happy, because those yellow leaves will make a "click" sound as soon as they step on it, just like laying a carpet on the road. It was really fun!

The cold winter has come, the cold wind is howling, all the leaves have fallen, the grass and flowers have lost their primary colors, and the branches have no leaves. The bare appearance is simple, but when it snows heavily, there is a layer of white snow flowers on the ground and a white quilt is covered on the ground. How beautiful!

The botanical gardens in the four seasons have different scenery, but each season has its own flavor!

I like a plant called "succulents". My mother keeps many such plants, which we affectionately call "succulent flowers".

Most fleshy flowers are lotus-shaped, some are crystal clear as jade, and some are smooth and tender if frozen. Sometimes I can't help but want to pinch them, because they are really cute.

Their names are interesting, some are Chihuahua, some are Xiong Haizi, and some are Moon Rabbit Ears. Chihuahua is as cute as Chihuahua, Xiong Haizi's leaves are like bear's claws, and the moon rabbit's ears really stand up like rabbit's ears. It's amazing!

Mom said that succulents, whose hometown is in South Africa, are natural wild plants. They grow on barren sand and have super vitality! Natural drought makes them instinctively store water, and meat changes with the seasons to make their leaves colorful, so they become more beautiful. The leaves of succulent flowers, like flowers, have a nice nickname "flowers that never fade", which is also the reason I like them.

My mother takes care of these little creatures every day and gives them plenty of sunshine and ventilation. My mother said that only in this way can meat grow well. Coupled with the beautiful flower arrangement device, it is simply a work of art.

I think I should learn from the tenacious spirit of succulents, overcome difficulties, study hard and be an excellent student.
