Nature s Revelation Essay 400 Words Must 400 Words

There are many mysteries in nature, and today I discovered a small "secret", that is: I discovered why the ants moved and it would rain heavily tomorrow.

In the past, I was curious about this question. When I was seven years old, one day, when I was playing on the grass in the suburbs, I noticed a large group of small ants walking in a long line towards a small hole, and each of them had something like little sand on its body, and I thought to myself: What are these little sand grains?

My mind was full of question marks, and I went to my father out of curiosity and asked, "Dad, why do the little ants walk in a long line to the entrance of the small hole?" Every little ant has something like a grain of sand on its body?

Later, my father told me: "That's because every time the little ants encounter a stuffy situation, they will tell the "ant colony", and when the ant colony learns about this situation, they will move immediately, and the weather is hot and humid, and it will rain heavily the next day, and the little ants will find a small hole to shelter from the wind and rain, and they will move because their previous house will be damp, so they have to move." The little grains of sand on the little ants are the food of the little ants.

Oh! That's when I realized! I have one more small question, and that is:

Why can ants rain until the next day? Dad said, "Ants are the same as us humans, they also feel stuffy, so when ants feel stuffy, it will rain the next day."

I learned another truth. I also heard my dad say, "If people see ants moving, it will rain heavily tomorrow."

This also confirms the proverb, that is: ants move snake aisles, and there will be heavy rain tomorrow! "I know it's going to rain heavily tomorrow, so I wonder why it's so magical.

I remembered another sentence: I don't know what absolute truth is, but I am humble about my ignorance. I didn't know that little ants could help people so much, and I believed in another saying, and that is:

When they awakened, they said to me, "You and the world you live in are nothing but a grain of sand on the boundless shore of the boundless ocean. "In a dream I said to them:

I am the boundless ocean, and the world is but a grain of sand on my sandy shore. I also want to tell the ants, "You are not the youngest.

Nature is our inspiration and the teacher of mankind, and it brings people wisdom and imagination.

Cacti, ants, these natural things are everywhere, so they are not unusual, but don't underestimate them.

Have you ever seen a swarm of tiny ants, crawling around the walls, carrying food as small as sand, walking in swarms? That small body, life is very weak, as long as it is pressed by others, its life may end like this. Ants are small, but very united.

When an ant finds food and is too large to carry it on its own, it immediately returns to its nest and informs its partners that together they can succeed. We are the same, if we can't unite, like a plate of scattered sand, we have no strength at all; If you can cooperate, you can stand tall in the world.

Cacti live in desert areas, where the heat is extremely high and there are many vicious beasts, which are very dangerous. But the cactus has lived there for a long time, but it has not become extinct, because it has grown sharp spines in order to adapt to the harsh environment, which makes the animals helpless. This seems to tell us that we must overcome difficulties, and we must rely on our own strong perseverance to solve the external difficult environment.

As the saying goes: There is nothing difficult in the world, but I am afraid of those who have a heart. That's it.

In nature, there are so many revelations to us, as long as we experience it with our hearts, we can have a deeper understanding of life, like cacti, ants, aren't they all good examples.

Nature's revelation to humanity.

Nature is beautiful nature, and we should protect it, not throw garbage, spit on it, and cut down trees.

Once upon a time, there was a village where he didn't like to protect nature, so he cut down trees and made chairs and tables from them. People went to cut wood to make houses, and when the houses were finished, the people in the villages shouted happily, and some of them were so proud that their houses were more beautiful than others, so people cut down trees every day.

Soon the flood came, and the flood destroyed the village, and the more beautiful houses were washed away by the fierce flood, because there were countless houses that were washed away, and this place became a ruined area.

Nature is so good, why should anyone destroy it? Let me say it! Because some people have nowhere to throw it, they can't throw it into the ground, some people think that throwing garbage is just like that, there is no tutor, and there are people in our class who don't eat apples and draw on them, how hateful it is, and some people eat fragrant mouths and spit out in the ground to make trouble for the students on duty, learn to listen in such a good environment, that group of small bones of the ant gang is to teach us unity, and the bees to collect honey are to teach us to be industrious, you see how beautiful nature is, to destroy it.

Be mindful of learning everywhere.

Early in the morning, I found a spider web in the corner of my house, and my curiosity drove me to catch a small grasshopper and put it on the spider web.

At this moment, a spider crawled out of the crack in the wall, and it spat out a stream of white silk around the grasshopper, wrapped the grasshopper, and returned to the hole. I wondered: why did the spider go back to the hole, why didn't it eat the grasshopper?

I continued to observe. But after waiting for a long time, the spider just won't come out.

The next day, I was amazed to find that the spider had eaten the grasshopper, leaving only an empty shell on the web. I wondered, why don't spiders eat their shells? In order to find the answer, I looked through a lot of materials and finally found the answer in "100,000 Whys".

It turns out that after the spider catches the prey, it first winds the prey with silk, and then spits out a digestive juice and injects it into the prey, which can dissolve the internal tissues of the insect composed of proteins, and after the insect is dying, it will turn into juice. The spider can suck it in a big gulp. Because the shell of an insect is not made up of proteins, the shell of the grasshopper is left intact in the net.

Through this unexpected discovery, I learned the mystery of spider eating. Although this is only a small discovery, it has taught me a truth: pay attention to learning everywhere. In fact, there are endless mysteries waiting for us to explore and discover.

I'm proud of my little discovery.

Comments: The assignment is small and big, and from a chance discovery in life, I understand a profound truth. Using his "curiosity" as a clue, he found a way for spiders to hunt their prey, which can be said to be ingeniously conceived.

What is even more valuable is that the article does not tell us the results of our findings, but focuses on revealing a truth.

You can read more books, how lazy.

Since the invention of electric light, life has become much more convenient and richer. You don't have to light candles at night. However, electric light can only convert a small part of the electrical energy into visible light, and most of the rest is wasted in the form of heat, and the heat rays of electric lights are harmful to the human eye.

So, is there a light source that only emits light but does not generate heat?Nature has given us some inspiration.

In nature, there are many organisms that can emit light, such as bacteria, fungi, worms, mollusks, crustaceans, insects and fish, etc., and most of the light emitted by these animals is ultraviolet light, which causes little thermal effect, so it is called cold light. If most of the emitted infrared rays are large, and the thermal effect is large, it is hot light, and the microwave oven is mainly hot light.

Among the many animals that emit light, fireflies are one of them. There are about 1,500 species of fireflies, and the colors of their cool light range from yellow-green to orange. The brightness of the light also varies.

The cold light emitted by fireflies has a high luminous efficiency, the intensity of the light is relatively high, and the cold light emitted is generally very soft, which is very suitable for our eyes and will not affect our vision. So, biolight is a kind of human ideal light. Scientists have found that the glowing device of the firefly is located in the abdomen.

This luminaire is composed of three parts: a light-emitting layer, a transparent layer and a reflective layer. The luminescent layer has thousands of light-emitting cells, and they all contain two substances, luciferin and luciferase. Under the action of luciferase, luciferin fluoresces when it is oxidized with the participation of intracellular water.

The luminescence of fireflies is essentially the process of converting chemical energy into light energy.

As early as the 40s, based on the research data of fireflies, people created fluorescent lamps, which made the lighting source of human beings change the world. In recent years, scientists have isolated pure luciferin from the luminescent device of fireflies, and later isolated luciferase, and then chemically synthesized fluorescein. A biological light source composed of a mixture of luciferin, luciferase, ATP (adenosine triphosphate) and water, which can be used as a flash lamp in mines filled with ** gas.

Since this light has no power source and does not generate a magnetic field, it can be illuminated by a biological light source to remove magnetic mines.

Nature has given us a lot of inspiration, and we are also moving towards the new century in the inspiration of nature.

After reading the book Animal World, I learned about the life characteristics and special abilities of woodpeckers and anteaters, and from them, I suddenly thought of a question, and at the same time got an inspiration:

In rural orchards, we often find pests burrowing into tree trunks and ripe fruits, and in order to protect the orchards, farmers have to constantly spray pesticides in large quantities. Not only is the cost high, but also when people eat it, the excessive pesticides make people daunting, if the pest control is not timely, people have to cut down those "incurable" fruit trees painfully. In the modern countryside, it is impossible to have so many woodpeckers to help the fruit trees to see a doctor.

Nature has taught us a lot of things, airplanes are based on dragonflies, and manicures are modeled after whales at the bottom of the sea, so I thought: why don't we build a lightweight exterminator based on the beak of a woodpecker and the tongue of an anteater? In this exterminator, we can install a computer chip, so that it can accurately detect diseased trees, and then, we can press a red button on the handle, from which a sharp, hooked steel pipe like a woodpecker's beak will pop out, it can accurately punch a very small hole in the tree of the pest, and then hook it out with a hooked steel pipe mouth.

What if it's termites? Don't panic, we can put the steel pipe mouth in first, and then, press the green jian, a tongue that imitates an anteater will bounce from it, and the long sticky tongue will be easily wiped out as soon as it "drills" into the hole.

From the woodpeckers and anteaters foraging, we got an inspiration and thus an innovation.

We live in the midst of nature, where the woods are lush, the flowers are blooming, the scenery is enchanting and unfathomable.

We humans invented radar with bats, the antenna of the radar is like the mouth of the bat, the radio waves emitted by the radar are like the ultrasonic waves of the bat, and the fluorescent screen of the radar is like the ears of the bat.

Humans invented airplanes with birds. The Wright brothers wanted people to take to the skies, so they watched the birds soaring in the sky every day, and invented the world's first airplane. The wings of a bird are the wings of an airplane, and we humans cannot go to high altitudes, otherwise we will not have enough oxygen and will have difficulty breathing.

At the end of the dragonfly's wings, there are thick spots that are slightly heavier than the surrounding areas, which is the key to preventing wings from fluttering, and humans have further studied the dragonfly's wings, and used the dragonfly's wings to solve another problem.

In the past, the ship sailing in the sea was always not fast, but later people found that the round big-headed whale can often easily overtake the ship, and the original whale has a "streamline" type, which greatly improves the speed of the ship.

Luban invented the sharp saw out of straw. One day, when Lu Ban went to cut wood, he accidentally fell and found that his hand was cut by the straw, and he looked at the straw and found that the straw had uneven teeth, so he invented the saw.

Nature is infinitely mysterious, we humans rely on animals and plants to show science and technology, as long as we humans learn the skills and actively invent and create, life will be better day by day!

Humans have discovered something from dragonflies and whales, and there are also inventions in flies that everyone hates!

Entomologists have found that the hindwings of flies degenerate into a pair of balancing rods. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the direction of movement of the wings and is a navigator that keeps the fly's body balanced. According to this principle, scientists have developed a new generation of navigator - vibrating gyroscope, which greatly improves the flight performance of the aircraft, which can make the aircraft automatically stop dangerous rolling flight, and automatically restore balance when the body is strongly tilted, even when the aircraft is in the most complex sharp turns.

The fly's compound eye contains 4,000 single eyes that can be imaged independently, and can see almost 360 of them. objects within range. Under the inspiration of the fly's eye, people made a fly's eye camera composed of 1329 small lenses that can take 1329 high-resolution photos at a time, which is widely used in military, medicine, aviation and aerospace.

React. According to the structure of the fly's olfactory organ, scientists have made a very sensitive small gas analyzer by making the fly's sense of smell particularly sensitive and can quickly analyze dozens of odors and can immediately convert various chemical reactions into electrical pulses, which has been widely used in spaceships, submarines and mines to detect gas composition, making the safety factor of scientific research and production more accurate and reliable.

Nature is a good teacher for man!

And one more. I also want to learn from scientists, take inspiration from animals and plants, and design small inventions.

Nature is the teacher of man, and scientists have learned many things from animals and plants. For example, the previous TV tower was not strong, and the strong wind could fly 80 meters away in one second, and the wind like this could blow the TV tower down, and people got inspiration from the fir tree to build the TV tower like a fir tree, so it would be good, no matter the wind and rain, the TV tower could not fall; Scientists also got inspiration from sharks, inventing swimsuits, reducing the resistance ...... water

I also want to learn from scientists, take inspiration from animals and plants, and design small inventions.

The gecko's hands and feet are very attractive and can easily climb up the wall without falling off. I'm going to design a shoe that looks like a gecko's hands and feet, and the name of this shoe is "Suction Invincible". It is convenient, when the worker paints the wall, you don't need to bring a ladder, you only need a pair of "suction invincible" shoes to start work, it not only adsorbs, but also reduce your weight, even if you brush the wall upside down, there are two buttons on the right side of the shoe, press the green button, it can let you move up and down on the wall, never fall down, press the red button to come down.

Do you find it convenient? When I really invent "Suction Invincible", I will definitely give it to the workers who clean and build houses.
