Desperate for the fourth grade composition "Enlightenment from Nature"

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 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 under the slightest noise or interference. In ancient times, lightning burned the forest. The ancients found that food after fire is more delicious than raw food, and fire can keep warm. When two stones collide, there will be sparks, so they learned to make a fire. The ancient people found that plants could grow when seeds fell into the ground, so they learned to farm. ..... Birds have wings to fly, so they invented airplanes; ......

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, there would be no such developed civilization as human beings now!

Squid and torpedo bait The capsule in squid can secrete black liquid, and when it is in danger, it will release this black liquid to trick the attacker into falling for it. Submarine designers imitate this function of squid, and readers design torpedo bait. Torpedo vinegar lure is like a pocket submarine, which can sail at the same speed according to the original course of the submarine, and can also simulate noise, spiral beat, sound signal and Doppler tone change. It is this vivid performance that makes it difficult to tell whether the enemy submarine or the attacked torpedo is true or not, and finally makes the submarine escape.

Ships and submarines are modeled after fish and dolphins.

Nature is beautiful, we should protect it, it gives us so much inspiration, we should not destroy it.

Scientists invented the plane that human beings dreamed of, but sometimes it became people's troubles: the plane crashed and people died, and the wing of the plane was broken! Why is this? In fact, dragonflies have already solved this problem. Dragonflies have a black spot at the end of their wings, which is a little heavier than the wings themselves. This point is used to stabilize the vibration of the wing. If scientists had known this, there would have been fewer accidents!

Compared with a sharp boat, a whale with a round head will say that the boat is fast, but it is actually much faster than a whale, because engineers find that the whale's shape is extremely ideal-streamlined!

What a revelation nature has given us!

=================================================================

Enlightenment of nature to human beings

Nature is beautiful, so we should protect it. We shouldn't throw rubbish, spit and cut down trees. Then, I will tell you a story.

Once upon a time, there was a village. He doesn't like to protect nature, so he cuts down trees and makes them into chairs and tables. Soon, everyone in the village felt that the house was old and should be replaced. People went to chop wood to build houses, and the houses were finished. People in the village there cried happily. Some people were very proud. Their houses were more beautiful than others. In this way, people cut down trees every day.

Soon the flood came and the village was completely destroyed by the flood. Even the most beautiful houses were washed away by the fierce flood, because some houses were washed away because of countless obstacles, and this place became a wasteland. This story is for everyone not to pick up the land indiscriminately.

Nature is so good, why would anyone want to destroy it? Let me talk! Because some people have nowhere to throw, they can't throw them underground. Some people think it's just a waste of garbage and no tutor. In our class, some people don't eat apples, but also draw pictures on them. Some people chew and spit on the ground, which makes life on duty very troublesome. In such a good environment, they learned to listen. The small bones of ants help us unite, while bees collect honey and teach us to work hard. Do you think nature is so beautiful that you are willing to destroy it?

The revelation of nature

The ancients had an extremely profound saying: Learn from nature. Great! Nature has indeed taught us many, many lessons, and each lesson is more exciting than the next. Listen to a story first.

Story 2: In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep impression on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed doomed to failure, but a miracle happened. The tree didn't strangle, but stood firm and tried to suck. Is it personal? ィ《? Do you want to blow the sword first? What's wrong with this book? @ Let's talk about Mina first ┲ Ⅲ ∷? What is Lu Chu's lawsuit? ナナナ史史 Lamby? What's wrong with the welding line?

Look! How profound nature is, although silent, it can give people extraordinary power.

Yes, there are many similar stories. Mature ears of wheat droop their heads, which is teaching us humility. A group of ants can carry big bones, which is teaching us unity. Gentle water drops can pass through rocks, which teaches us tenacity. Bees are busy shuttling among flowers, which teaches us to work hard. The poor grass silently closed the leaves, which told us not to overstretch the fields.

Yes, nature is the best teacher. As long as we are willing to study, we will gain something every day.

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 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." This is a fact.

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

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.

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.

17。 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.

18。 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.

19。 Not long ago, the bionic research team of Illinois State University developed a set of artificial lateral lines that can give robots a "sixth sense", similar to the lateral line system of fish. This artificial lateral line consists of many tiny silicon wafers arranged on the surface, which are similar to hair bundles, and each silicon wafer is connected to an electronic sensor through a micro chain. When the water flows in contact with the silicon beam, the silicon beam will bend due to the different speed of the water flow, so that the sensor can detect the bending angle and direction of the silicon beam, thus helping the robot find the desired direction.

20。 Albatross is a kind of seabird, and it has an organ that desalinates seawater-a "desalter". The research on the structure and working principle of its "desalter" can inspire people to improve old or create new seawater desalination devices.

The submarine was inspired by fish.

According to legend, Luban once went up the mountain to cut wood, and his skin was cut by a kind of toothed grass, so he got inspiration from it and invented the bamboo saw.

The ancients gained the freedom of water transportation by imitating fish living in water, cutting down trees and chiseling boats, making fish-shaped hulls out of wood, and using fish pectoral fins and caudal fins to paddle and paddle.

The ancients had an extremely profound saying: Learn from nature. Great! Nature has indeed taught us many, many lessons, and each lesson is more exciting than the next. Listen to a story first.

Story 2: In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep impression on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed to be dying, but a miracle happened. The tree didn't strangle, but stood up firmly and swallowed the terrible iron hoop alive! And all this happened to be seen by a desperate old man, and he summoned up the courage to live. The old man has cancer! He overcame his illness and survived. Duohuo

Is that okay?

Some of them were found by themselves, and some were written by themselves.
