The revelation of nature is 400 words.

In ancient times, people saw fish swimming freely in the water, so they invented boats and paddles based on fish's breasts and fins. When people saw birds flying in the sky, they invented airplanes and realized their wish of "flying to the blue sky".

In the past, tanks had only one floor. If the enemy is on the right wing, it is necessary to airdrop the whole tank. People get inspiration from turtles. The tortoise can face in any direction on its back. Therefore, man invented the rotating gun.

I saw children playing with remote control boat and my friends playing with automatic planes, so I thought: remote control boat is propelled by propellers, and automatic planes are driven by springs, so automatic ships should be driven by springs. I went home and tried, and it worked, but I couldn't fly fast. I think dolphins have triangular tails. They swim very fast. I made the stick at the tail into a triangle, and it succeeded.

Nature has given us so much inspiration!

Humans have found something from dragonflies and whales, but flies have inventions that everyone hates!

Entomologists found that the back wings of flies degenerated into a pair of balance bars. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the direction of its wings. It is a navigator to keep the balance of flies. Based on this principle, scientists have developed a new generation of navigator-vibrating gyroscope, which greatly improves the flight performance LlJ of the aircraft, enables the aircraft to automatically stop the dangerous rollover flight, and automatically restore the balance when the body is strongly inclined, even when the aircraft is in the most complicated sharp turn.

The fly's compound eye contains 4000 single eyes that can be imaged independently, and almost 360 can be seen clearly. Objects within range. Inspired by the fly's eye, people made a fly's eye camera consisting of 1329 small lenses, which can take 1329 high-resolution photos at one time. It is widely used in military, medical, aviation and aerospace fields.

Flies have a particularly sensitive sense of smell and can quickly analyze dozens of smells and respond immediately. According to the structure of flies' olfactory organs, scientists have converted various chemical reactions into electric pulses, and made a very sensitive small gas analyzer, which is widely used in spacecraft, submarines, mines and other gas components, making the safety factor of scientific research and production more accurate and reliable.

Nature is really a good teacher for human beings.

Once upon a time, there was an old man whose life was a forest. If someone destroys the forest, he will fight him desperately. One day, the old man was ill, and his illness was difficult to treat. After asking around, the old man's son finally found something that can cure this disease, that is, woodpecker.

Because the old man's sons know that woodpeckers can cure diseases, they all go to catch woodpeckers. We have to catch dozens of them a day and stew them for the elderly. Because my son keeps catching woodpeckers, there are fewer and fewer woodpeckers in the forest. Insects breed, attack trees, eat leaves, bite roots and drill into the heart of trees. There are no natural enemies to deal with them, so the forest is gradually destroyed.

The old man finally recovered from his illness and went into the forest at the first time. What I saw was a scene of suffering, with dead branches and leaves everywhere. The old man shed tears when he saw the forest destroyed. The old man came home disappointed. A few days later, his illness recurred and he died.

Have you ever seen a mountain? This mountain is very big. Have you ever seen the sea? The sea is vast. I have always believed that people can understand a lot in nature. Nature contains many philosophies of life. Just like the moon, the full moon and the lack of the moon represent the reunion and separation of relatives and friends. Ants and aphids show cooperation and mutual assistance in order to survive. Have you ever seen a bee living alone? They pay attention to the spirit of unity and division of labor.

Nature has also brought me years in a hurry, so I must cherish the enlightenment of time. Look at the sunrise and sunset, as if the sun has just risen, but the stars and the moon are sparse in the blink of an eye. Cordate telosma quietly blooms and fades. If the fallen flowers and leaves once represented the end of a gorgeous life, it would be too short. The glory when the bud was born suddenly turned into lifeless dryness! Butterflies will also die in the cold fragrance of flowers in Xia Hou during the busy season.

Life is short, but if we can make it shine, it can be called eternity, can't it!

Enlightenment of natural constituent materials

Japanese scientists were inspired by ants foraging. They developed a large-scale integrated circuit to simulate the foraging ants Qixin carrying food together and sending information from the nearest "food source" to the "ant nest" in sequence. According to this new information processing method, it is possible for people to develop a computer with a new computing mode.

There are still many inspirations from nature, such as: imitating the characteristics of egg shape and building arch bridges; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... There are many animals and plants in nature, which hint at the mysteries of nature in their own unique way of life.

There are many inspirations from nature. There is a kind of snake called rattlesnake. It has an infrared eye. Through the eyes of this snake, human beings have developed a missile with eyes like rattlesnakes. Its name is rattlesnake missile, so it is named rattlesnake missile, because humans are made according to the eyes of rattlesnakes.

Sidewinder missiles, like rattlesnakes, can accurately track the enemy with "hot eyes" until they are destroyed. Because the "hot eye" of the rattlesnake judges the position of the enemy according to its temperature, the rattlesnake missile can accurately hit planes, warships, tanks and the like. The mobile low-altitude short-range all-weather ground-to-air missile developed by France is mainly used to deal with low-altitude and ultra-low-altitude fighters and armed helicopters to defend the airport. It can also be used against cruise missiles. The missile is 2.94m long, with a diameter of 0. 156m, a weight of 84.5kg, a launcher length of 3.02m, a warhead focused on fragments, a total weight of 13.9kg and a killing radius of 6 ~ 8m m. The power plant is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance with a combat radius of 500 ~.

Colorful butterflies, such as butterflies with double moon stripes, monarch butterflies with brown veins, especially butterflies with fluorescent wings, have their hind wings that turn from golden to green and from purple to blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defense facilities with bombers. According to people's camouflage at that time, Vanovic, an entomologist in the Soviet Union, suggested that the color of butterflies was not easy to be found in flowers, and military facilities were covered with butterfly-like camouflage. Therefore, although the Germans went all out, the military base in Leningrad remained safe and undisturbed, laying a solid foundation for winning the final victory. According to the same principle, people later produced camouflage uniforms, which greatly reduced the casualties in the battle.

The beehive is composed of hexagonal small beehives arranged neatly, and the bottom of each small beehive is composed of three identical diamonds. These structures are exactly the same as those accurately calculated by modern mathematicians-rhombic obtuse angle 109.28' and acute angle 70.32'. They are the most material-saving structures, and they are large in capacity and extremely strong, which makes many experts admire them. People imitate their structures and make honeycomb sandwich panels with various materials. It is not easy to conduct sound and heat, so it is an ideal material for building and manufacturing space shuttles, spaceships and artificial satellites. A polarizer sensitive to the direction of polarized light is arranged adjacent to each monocular of the compound eye of bees, which can be accurately located by using the sun. Based on this principle, scientists have successfully developed a polarized light navigator, which has been widely used in navigation.

Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and wells use the vortex generated by the airflow to lift themselves up. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and the forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is relatively simple, with only two pairs of wings constantly flapping. Scientists have successfully developed a helicopter based on this structure. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks the wing, resulting in the plane crashing. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add counterweights to the wings of aircraft to solve the thorny problem of vibration caused by high-speed flight.

Fleas have a high jumping ability, and aviation experts have done a lot of research on it. Inspired by its vertical take-off, a British aircraft manufacturing company has successfully manufactured a harrier aircraft that can take off and land almost vertically. According to the structural characteristics of insect's single compound eye, modern TV technology has made a large-screen color TV, and can also make a small color TV screen into a large picture, and can frame several specific small pictures at any position on the same screen. The same picture and different pictures can be displayed. According to the structural characteristics of insect compound eyes, scientists have successfully developed a multi-aperture optical system device, which is easier to find targets and has been applied in some important weapon systems abroad. According to the mutual inhibition principle of some aquatic insects compound eyes and monocular eyes, an electronic model of lateral inhibition is made and used in various photographic systems. The photos taken can enhance the image edge contrast and highlight the outline. It can also be used to improve the display sensitivity of radar, and can also be used for preprocessing of character and image recognition systems. Based on the processing information of insect compound eye and the principle of directional navigation, the United States developed an engineering model of terminal guidance seeker imitating insect compound eye search. Japan has developed new construction methods of construction machinery and buildings such as hexapod robots by using the morphology and characteristics of insects.

The survival of human beings depends on nature, and the development of human beings is based on the revelation of nature. Without the revelation of nature, human beings would not be so developed now ... The revelation of nature to human beings is that nature is beautiful, so we should protect it and not throw garbage, spit or cut down trees.

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, supported by a wheel spoon, and the 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.

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.

People have successfully designed an accurate "jellyfish ear" instrument by simulating the organs of jellyfish that feel infrasound waves. It consists of a loudspeaker, a vibrator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. This instrument can forecast storms 15 hours in advance.

The compound eyes on both sides have the greatest influence on the behavior of horseshoe crab. After being irradiated by the light beam, the compound eye produces a pulse. One eye is irradiated by the light beam, and the other eye generates the main pulse; Both eyes are irradiated by light beam at the same time, and both eyes generate pulses at the same time, but the frequency of pulses generated by light beam irradiation on one eye is slightly lower. Inspired by it, mankind has successfully developed an electronic simulation device, which can solve the network equation composed of 10 elements. The TV camera made by applying this principle can provide high-definition TV images under laser.

Without nature, there would be no beautiful earth. Let's join hands to protect nature and the earth.

Reflections on Reading the Revelation of Nature

I love reading since I was a child, and I am a "little book fan". I have read Grimm's fairy tales, education of love, dear Mr. Han Xiu, open sesame, Romance of the Three Kingdoms, Cricket in Times Square, Dream of Red Mansions ... I like reading all books that are helpful to my study. I not only bought it myself, but also borrowed it from my classmates and even went to the library to read books.

This week, our teacher assigned an assignment, that is, let us read the fourth unit of Chinese reading-the revelation of nature. This homework makes me very happy, because I especially love reading, so this homework is simply a kind of entertainment for me.

Many people say that we should love nature, but what is nature? I'm afraid I don't know. In fact, what is nature? I didn't know it at first, but I understood it after reading the article in this unit! Nature is actually some natural phenomena. In Zhi Tao, nature actually affects people's mood, and nature is actually our living environment. Simply put, nature is an unknown person who has contributed to mankind.

The vast nature is great and selfless. It not only provides us with a living environment, but also exerts a subtle influence on the mood of Zhi Tao people. The gradual change of day and night, the replacement of spring, summer, autumn and winter; Quiet and solemn trees and verdant grasslands make us feel the emotion, will and wisdom of nature.

We live in harmony with nature every day, and its magic and beauty leave us with infinite reverie. Many scientists got inspiration from it and made inventions, which greatly improved our lives.

Frogs have very special eyes. They are very keen on watching moving things, but they are very slow on still things. People invented the "electronic frog eye" by using the characteristics of frog eye, so that people in the airport can accurately command the plane to land.

Banana leaves are arranged in a spiral shape, which can get enough sunshine. Therefore, the house built by architects according to this shape can also make every room enjoy warm sunshine.

People still get a lot of inspiration from nature. For example, the "law of gravity" was discovered in "Falling from the Apple"; Invented "anti-load flight suit" from "giraffe's body structure"; Inventing "Modern Night Vision Device" from "Rattlesnake" ...

This shows that the world is full of miracles. As long as we observe carefully and dare to explore, even a grass will have its wonders and bring us thousands of inspirations. Therefore, while enjoying nature, we should also discover and observe many mysteries, make rational use of them, provide more convenience and make people's lives better.

Nature is the best teacher for human beings. Careful observation will yield a lot!

For example: scientists study frog eyes and invent electronic frog eyes; The first gas masks in the world were made according to the unique drug detection ability of wild boar nose. Lu Ban discovered a kind of thorny grass and invented a saw.

Bats are mammals, and they are viviparous. At night, it is an expert in catching pests in the night sky. No matter how fast an insect flies, it cannot escape his eyes. Just say mosquitoes. Mosquitoes are small and thin, flying fast and light, but if they meet their natural enemies-bats, they are like panicked bulls. They don't know what to do, and they will never escape from the bat's palm. So humans invented the mosquito repellent lamp.

Although flies are a kind of pests that do little harm to crops, people also get inspiration from flies.

The fly's eye is a kind of "compound eye", which consists of more than 3000 small eyes. People imitated him and made a "fly glasses", which was made up of hundreds or thousands of small lenses arranged neatly. Using him as a lens, you can make a "fly-eye camera" and take thousands of identical photos at a time. This kind of camera has been used for printing, plate making and copying a large number of tiny circuits of electronic computers. Greatly improved the work efficiency and quality.

The magical nature has given us a lot of inspiration and benefited mankind. We should protect nature.

Spring has come, and the grass sticks out its head. In Yuan Ye, the green grass grows densely together, bringing infinite vitality to the earth! Just like a poem by Bai Juyi, a great poet in the Tang Dynasty, praising grass: the grass is boundless, and the four seasons come and go. Wildfire can't burn it out, but the spring breeze can revive it.

I like grass and its tenacious vitality. Grass, it doesn't need anyone to water and fertilize, just a handful of loess and a beam of sunshine can thrive. Beijing is full of street gardens. There is a lawn with green grass in my street garden. In spring, the ice and snow have just melted, and many delicate flowers are still hiding in the greenhouse, afraid to come out. The grass held its head high and stretched its yellow and green arms. This group of "little green angels" first brought people the message that spring has come.

I love grass, love its strong character and dare to challenge the storm. In midsummer, after the strong wind, the raindrops as big as beans flew straight down, beating the grass stagger and bending over. However, before long, it will straighten up again. How strong this grass is!

I love grass and their ordinary, simple and selfless dedication. Thousands of laborers in Qian Qian, like grass all over the world, create a better life with their ordinary labor, adding luster to this big garden of the motherland!

The revelation of nature

Nature is wonderful. Inspired by it, people invented many things and promoted the progress of human society.

People have always dreamed of flying in the air like birds. Although China people invented kites more than 2000 years ago, they can't take people into the air.

At the beginning of the 20th century, the United States invented the airplane. They are the Wright brothers. 1903, they built the first manned aircraft "Voyager 1" on their own, and the test flight was successful. Therefore, they won the honorary award of 1909 from the US Congress. Since the invention of the airplane, it has become an indispensable means of transportation for modern civilization, profoundly changing and affecting people's lives. Since then, people have realized their dreams in heaven.

Since people have realized their dreams in heaven, they also dream of swimming at the bottom of the sea like fish.

The first submarine in the world is oval and can only dive 7 meters. After the submarine company put into commercial operation, the number of accidents caused by submarines continued to increase, and the number of passengers on submarines continued to decrease. Then the submarine company went bankrupt. One year, when this country wanted to go to war with another country, they replaced the submarine with an egg and took it to bomb the imperial warships, but they had to return because they were not familiar with the operation. However, since then, submarines have been used in wars and designed more and more advanced.

In addition, people also invented the sucker that imitates the gecko, the jumping car that imitates the kangaroo and the super high-rise building that imitates the straw. ...

What a revelation nature has given people!

We live in nature, where the Woods are lush, the flowers are in full bloom, and the scenery is fascinating and unfathomable.

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

Man invented the airplane through birds. The Wright brothers wanted people to fly into the sky, so they watched birds soar in the sky every day and invented the world's first plane. The wings of a bird are the wings of an airplane. We humans can't climb very high in the air, otherwise we will be deprived of oxygen and have difficulty breathing. At the end of dragonfly wings, there is a thick point slightly heavier than the surrounding, which is the key to prevent the wings from shaking. Humans have further studied the dragonfly wings and solved another problem of dragonfly wings.

In the past, ships sailing in the sea were always slow. Later, it was found that round whales could easily overtake ships. It turns out that whales are "streamlined", which greatly improves the speed of sailing.

Lu Ban invented a sharp saw with straw. One day, Lu Ban went to chop wood, accidentally fell down and found his hand cut by straw. When he looked at the straw, he found that it had jagged teeth, so he invented the saw.

Nature is endless, and we humans have demonstrated science and technology with animals and plants. As long as we humans learn our skills well and actively invent and create, our life will be better and better day by day.
