Composition "Enlightenment from Nature"

Guess what? Nature is beautiful, so we should protect it. We can't throw rubbish, spit or cut down trees. Then, I will tell you a story.

Once upon a time, in the forest, there was a small village. Very lively. The people there are very friendly. They never cut down trees. They like animals very much. Animals in the forest never hurt people. Everyone lives in harmony and happiness.

But not long after, a man shouted on the mountain: "sell the axe!" " Sell axes! "It happened that a man passed by the mountain. The man who sold the axe asked the man who crossed the mountain, "Sir, do you want to buy an axe?" "People passing by this mountain don't know what it is, so they ask," What's this axe for? "Another man said," You can cut down trees with this axe and use it as a house. " The man thought about it. Originally, he didn't want to buy it, but he thought it was good and bought it.

He took it home and told his wife. The wife said angrily, "You can't cut down trees. What about those little animals? " Then they have no home. "The man said," what should we do for the sake of small animals? We all build straw houses. If it rains, then our house will be blown away. What house shall we build? If you cut down a tree and use it as a house, you are not afraid of anything. The wife said awkwardly, "All right." "The man went out to cut down trees.

He walked and met a fellow villager. When the fellow villagers saw him holding something in his hand, they asked, "What's that in your hand?" The man said, "It's an axe." The fellow villager asked again, "What are you doing with that axe?" The man said, "It can be used to cut down trees." The fellow villager was very angry and said, "You can't cut down trees." Hearing this, the man told his villagers what had just happened. The fellow villagers realized this. He said, "Where did you buy it?" The man said, "On the mountain." Hearing this, the villagers left before they could thank them.

Nowadays, more and more people buy axes and fewer trees. Small animals have no homes, and people are getting colder and colder.

Until one day, the flood came. Trees cannot stop. They drowned everyone and the whole village was gone.

This story tells us to protect.

This is reasonable.

Nature is a treasure given to mankind by God. Delicate every bead, every drop of dew, bathed in the sun, look at the rivers and mountains, nature is telling us one story after another. Indulge in nature, and you will feel the life feeling of "forgetting me"; Will realize that "the journey of the sun and the moon, if separated from it;" Star Han is talented, if it is unexpected, it is full of pride; I will understand the resentment of "rushing to the crown, leaning against the railing, rustling in the rain". Understanding nature is like reading a book, a book that shocks the soul and washes the soul.

Thunder rumbled, shaking the earth, shaking the mountains and disturbing the ears, and the river opened its mouth. This is the real heroism.

Lightning flew into the sky and danced with the frightened eagle and the frightened tiger. This is the real heroism.

That's what dead people do Youyou Cooper is covered with a lonely Shan Ye with thousands of years of vicissitudes. For it, the trace of tree rings is only a thousand years, but it clearly and truly records every track in its life. Looking up at Cooper, do you realize that this may be a euphemistic revelation and expectation from nature?

Feel the nature, and you will have the boundless mind of the sky, the courage of the surging waves of the sea, the indomitable power of the dangerous steel and diamonds. This is the meaning of heaven.

Feel the nature, miss the fallen leaves floating in the wind, the green grass that is soft outside and firm inside, the drizzle, and the meticulous affection of the animal kingdom. This is the halo of the moon.

Let's put aside all distractions with a feeling heart, walk into nature with a purity and innocence, and feel nature! You will find that everything in nature is so beautiful and magical.

This is a revelation.

1。 A very strange small gas analyzer was successfully copied from annoying flies. It has been installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin.

2。 From fireflies to artificial luminescence;

3。 Electric fish and volt batteries;

4。 The windward ear of jellyfish imitates the structure and function of jellyfish ear, and designs a storm predictor of jellyfish ear, which can predict the storm 15 hours in advance, which is of great significance to navigation and fishery safety.

5。 According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion.

Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.

6。 According to the principle of bat ultrasonic locator, people also copied "Pathfinder" for the blind. This pathfinder is equipped with an ultrasonic transmitter, which blind people can use to find telephone poles, steps, people on bridges, etc. Nowadays, "ultrasonic glasses" with similar functions have also been made.

7。 By simulating the incomplete photosynthetic mechanism of cyanobacteria, a bionic photolysis device was designed to obtain a large amount of hydrogen.

8。 According to the study of human skeletal muscle system and bioelectricity control, a human strength enhancer-walking machine is copied.

9。 The hook of modern crane originated from the claws of many animals.

10。 Corrugated roofs imitate animal scales.

1 1。 Paddles imitate the fins of fish.

12。 Saw mantis arms, or saw grass.

13。 The plants of Xanthium were inspired to invent velcro.

14。 Lobster with keen sense of smell provides people with the idea of making odor detectors.

15。 Gecko toes provide an encouraging prospect for manufacturing reusable adhesive tape.

16。 The colloid formed by shellfish and protein is very strong, and this colloid can be used in everything from surgical suture to ship repair.

The invention of mankind-inspired by animals-ships and submarines came from people's imitation of fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation.

Bionic and high-tech modern radar, a radio positioning and ranging device: scientists found that bat monsters rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bat magic emits ultrasonic waves when flying, it can also detect the ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device ... Scientists have invented an artificial dolphin skin that can improve the speed of torpedoes by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.

Inspired by King Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"King Penguin" brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface and supported by a wheel spoon, and the driving speed can reach 50 km/h.

Scientists make space robots by imitating insects.

A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip a small aircraft for Mars exploration.

Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate at the slightest sound or interference.

1666 or so, Newton had considered the problem of gravity when he lived in his hometown. During holidays, he often sits in the garden for a while. Once, as it happened many times before, an apple fell from the tree. ...

The accidental landing of an apple is a turning point in the history of human thought, which enlightens Newton's mind sitting in the garden and also causes him to think deeply: What is the reason why all objects are almost always attracted by the center of the earth? Newton mused. Finally, he discovered the gravity which is of epoch-making significance to mankind.

The origin of compound eye camera

The compound eye of an insect is made up of thousands of small eyes. Because of the mutual inhibition between small eyes, eyes have the function of highlighting the image boundary and increasing the clarity. People made a "fly eye camera" for scientific research by imitating the honeycomb structure of small eyes in flies' stomachs. You can take 1329 photos at a time with a resolution of 4000 lines.

The revelation of nature is: the origin of fly-eye camera: the compound eyes of insects are composed of thousands of small eyes!
