Three sample essays on China gardens in the second volume of the fourth grade of People's Education Edition.

Nature endows flowers with beautiful appearance, which has a special relationship with human beings. With the development and progress of the times, flowers have been closely related to human life. When you are in the sea of flowers, you may be intoxicated and enjoy the colorful and refreshing fragrance they bring, but do you know how their external beauty affects your health?

Lily symbolizes a hundred years of harmony, although it means beauty, but smelling the fragrance of lily for a long time will make the central nervous system excessively excited and cause insomnia, and orchids are in the same breath.

Chinese rose is romantic and beautiful, with a fragrant smell, but its smell will make allergic people feel chest tightness and breathing difficulties. The gas emitted by oleander is easy to make people suffer from bronchitis and pneumonia, which is not worth the loss.

Western hydrangea is different from the above flowers. Its odor is not very irritating to the human body, but long-term contact with its particles will make people itch.

While appreciating the beautiful appearance of flowers, we should also understand the inner mystery. Although they can decorate rooms, we must choose them scientifically.

Train of thought analysis: The author carefully observed the surrounding flowers, carefully understood them, and profoundly revealed the close relationship between flowers and human beings, with vivid language. The last sentence named the theme of the article.

Example 2, small vines

Our family moved to a new house last spring. In the small courtyard by the window, I accidentally found a new branch that had just spit out a bud. "What is this?" I asked my mother. Mother looked at it and said, "This is a vine." A vine! Seriously, I've only eaten grapes since I was so big, but I still don't know how grapes grow. Curiosity prompted me to have a strong interest in this vine.

At first, the small vine seemed to be ill, and there were only a few tender leaflets on a dry stem, which was very pitiful. Under the guidance of my father, I inserted two three-meter-high wooden sticks obliquely on both sides of the vine, put a piece of wood on it and tied it with a rope to form a natural trapezoidal arbor. Every day when I come back from school, I will look at the vines, and sometimes I will loosen the soil and water the small vines.

The vines grow gradually, and the dry stems become thick and green. There are many small branches on a tree trunk, and each branch is covered with green leaves. I observe it carefully every day. The vine of the grape is a section, and palm-sized leaves grow on each section. The leaves are upright, large and dense, leaving no gaps. As long as there is a frame, vines climb up. In a few days, the vines have grown taller than me.

More than a month passed, and one day, I suddenly found white flowers on my neighbor's vine. But I can't even find the shadow of a flower on my vine, which makes me very anxious. I asked my mother, "Mom, can our vines bloom?" "Our vines are damaged. As long as it is carefully cultivated, it will definitely bloom, and it may be a little late. " Mom said. This makes me more confident and more diligent in practice. Under my careful care, many small white flowers have grown on our vines. Flowers are small, mostly pink and white. After a few days, the flowers withered and a bunch of small grapes like small grains of rice grew.

In August, grapes grow as big as small apricot stones and become half black and half green. I am impatient. I picked one and put it in my mouth. When I bite, it is sour and astringent. Only then did I realize that the grapes were not fully ripe.

September in late autumn is the harvest season, and my grapes are ripe. Grapes have grown to the size of glass balls, and their colors are very bright, some are purple and some are dark green, which is very beautiful. I picked one and put it in my mouth. Ah! Sweet and sour! I gave the grapes to my parents so that they could share the fruits of their labor with me.

Looking at the grapes on the shelf and the fruits of my labor, I smiled happily.

Thinking analysis: Many of our students are worried about having nothing to write in their compositions. The author of this article carefully observed and cultivated the new branches spit out in the courtyard, described the growth process of small vines, expressed the sweetness of tasting fruits and realized the joy of labor harvest. After reading this composition, do you realize that life is full of articles, and you should pay attention to what you have learned everywhere?

Example 3, Little Turtle

There is a little turtle in my home. It's a little smaller than my fist. The beige hard shell is semi-arched. The little turtle's head is triangular, probably to reduce the resistance of water. Those small eyes are round and bright, very energetic, and there are two small nostrils at the front of the head, which is very interesting. Look again, the four calves are short and thick, covered with tiny scales and with five small claws at the end. By the way, there is that thin, short triangular tail, dragging it behind. This is very interesting.

Usually, the little turtle lies quietly in the water, sticks its head out of the water, and looks very "quiet". But the slightest movement, even footsteps, it will find, and immediately retract its head, revealing only two small eyes and a face of alert. For a long time, it will shake its neck and try to stick its head out bit by bit. The little turtle is really vigilant

I think, you won't believe this slow and clumsy little guy can catch fish! But this is wrong.

Once, I fed some small fish to the little turtle. It's funny. As soon as the little fish was put into the pot, its neck just shrank out, and its two small eyes were staring at the little fish. I wonder: can it catch small fish? This little fish is very clever, but it ... didn't expect the little turtle to be smarter. It didn't make a move, just lay there quietly, waiting for the opportunity. Little fish didn't think that their enemies were close at hand and were still frolicking. I held my breath and opened my eyes. Finally, a small fish swam to the little turtle. The little turtle deftly put out his head, opened his mouth and bit the head of the little fish. The little fish just wagged its tail twice and stopped. The little turtle climbed several more steps until it thought it was "safe" before enjoying its delicious meal with confidence. I saw its neck stretched out hard, apparently swallowing small fish, and its two front legs were still swinging back and forth, as if exerting force. Look, how interesting!

However, if you disturb it while eating, it will immediately put down the food, put its head out of the water to "spy" it, and then continue its delicious meal. It can be seen that even when eating, the little turtle refused to relax his vigilance!

Anyone who knows a little about history knows "Oracle Bone Inscriptions". In Shang dynasty, people once dug holes in tortoise shells and then burned them on fire. When these small holes burst into a "divination" shape, the diviner decides good or bad luck, and then engraves the prayer, result and divination date on the tortoise shell, which is the "Oracle Bone Inscriptions". Nowadays, people have obtained a lot of valuable information from tortoise shells and animal bones unearthed in Yin ruins.

Not only that, the meat of the tortoise is edible, and the tortoise shell can be used as medicine.

It seems that the little turtle is not only smart and lovely, but also an animal that is very beneficial to human beings!

Train of thought analysis: The author introduced the appearance and life habits of the little turtle in detail, vividly and interestingly with vivid language and affectionate brushwork. In particular, the scene of tortoise preying is more vivid, which shows that the author's careful observation gives people an image feeling after reading it, thus enhancing the specific understanding and understanding of the little turtle.

Revelation about nature

Fly eye invented the fly eye camera. Sensitive perception of flies, invented a danger detector, used in dangerous workplaces; The gliding skill of the eagle invented the glider. The shape of the bird's thread has changed the appearance of the plane and is more aerodynamic. The bones of birds have improved the skeleton structure of aircraft, making it lighter and stronger. Acoustic detection of bats and dolphins invented ultrasonic radar. Airplanes fly by radar at night, which is inspired by bats. Cactus, ants, these natural things can be seen everywhere, so it is not unusual, but don't underestimate them.

Have you ever seen a group of small ants crawling on the wall? They always carry food as small as sand and walk in groups. That tiny figure's life is very weak. As long as it is pressed by people, its life may end like this. Although ants are small, they are very United. When an ant finds food, because the food is too big for him to carry, he immediately returns to his nest and informs his partner that everyone can unite and succeed. We are the same, if we can't unite, we are like a loose sand, with no strength at all; If we can unite and cooperate, we can stand firm in life.

Cactus live in desert areas, where the heat is unbearable and there are many ferocious beasts. The situation is very dangerous. But the cactus lived there for a long time, but it didn't go extinct. This is because it grows sharp thorns to adapt to the dangerous environment, which makes animals helpless. This seems to tell us that we must rely on our own strong perseverance to overcome difficulties and solve the external difficult environment. As the saying goes, "Nothing is difficult in the world, only if you put your mind to it." That's the truth.

In nature, it inspires us too much. As long as we understand them with our heart, we can have a deeper experience of life. Aren't cactus and ants good examples?
