Write an essay on the revelation of nature. It s going to scare people

Nature has given many revelations to human beings, and it is the earliest "teacher" of human beings. There are many strange things in nature, and animals and plants have their own unique characteristics.

For example, when the wind blows, dandelions fly in the blue sky, like some elves dressed in white, people invented the parachute through its characteristic of fluttering with the wind, so that people will not be injured when they operate the parachute to jump down in the air.

Others were invented through animal revelations. For example, when a horse runs very fast, humans think: If only we could invent a machine that can run faster than a horse.

Time flies, and with the continuous development of science and technology, human beings have invented automobiles, allowing us to travel faster to our destinations. People also invented airplanes to imitate the flight of birds. At that time, if we were going to a far place, it was simply not fast enough to take a car, and people looked at the birds soaring in the sky and thought:

If only we could fly. Mankind invented the airplane again.

Human beings are intelligent, but if we don't have the "teacher" of nature, we wouldn't dare to think about it, let alone invent and create. It is precisely because of this "teacher" that human beings are able to imagine boldly and continue to invent and create.

Nature, the "teacher" of human beings, is precisely because of it, our life is no longer boring and ordinary, and our life has become full of imagination and colorful! Nature, you are the "teacher" of human beings: enthusiastic netizens | 2011-4-12 21:22

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.

Take a look at "Insects", it will make you have a lot of ideas and thoughts.

Nature's revelation.

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.

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.

Nature's revelations are easy to write about. As long as you pay attention, you can find out.

Normally, I hear adults say that bees die if they lose their needles. However, I am not convinced, how can a bee die without its spine?

One day, I was playing in the park and saw a small bee falling from the sky and falling to the ground, it struggled weakly, flapping its wings, and seemed to want to fly. I quickly grabbed it and held it in the palm of my hand. I found that it didn't have a spine on its tail, probably because it was injured by defending against enemies, so it's no wonder it didn't fight back when I caught it.

It didn't take long for the bee to die.

The question that bees would die if they lost their needles came back to me, so I turned on my computer and looked up the information and knew the answer. In the large bee family, a group of bees will have a leader, the queen bee, and the others will be worker bees and drones. The worker bee is the most abundant in a group of bees, it is an incomplete female bee, and the bee's needles are actually their ovipositor.

Because the worker bee is underdeveloped, its internal organs are connected to the bee needle, and the internal organs remain in the human body after it stings, and if there are no internal organs, of course it will die. Sometimes, the internal organs of the worker bees are only exposed to the air, and the bacteria in the air will corrode the internal organs of the worker bees, and the worker bees will slowly die. Whereas, drones do not lay eggs and do not have bee needles.

The queen bee is fully developed, and it will be fine to sting people, and the queen bee will only use the bee needle when competing for the "throne".

In our colorful world, scientists have invented many advanced devices based on the inspiration of nature.

For example, the fluorescent lamp was invented by the scientist Edison based on the cold light emitted by fireflies flying at night; Submarines were also invented based on the freedom of fish in the water; Dragonflies also provide many inspirations for the scientists who created the aircraft.

I thought to myself: if scientists can invent so many things with the help of nature's revelation, then we can also invent something with the revelation of the scenery in nature. So, I fell into deep thought, and suddenly, I saw a woodpecker healing the tree.

This big tree looks very thick, but there is no insect, we will definitely think that the tree is not sick, in fact, the insect is in the tree, the human eye can not see, and the woodpecker is relying on hearing to accurately judge the ** of the tree, accurately find out where the insect is, and then eat the insect in the tree, which is considered to cure the disease of the tree. The tree was indeed different from before, and before the woodpecker treated the tree, the tree was obviously dying, but after being cured, the tree regained its former vitality. Seeing this scene, I couldn't help but have a thought:

Woodpeckers heal so fast, I could invent a small robot that specializes in healing!

I thought, I want to invent a small robot with a unique appearance, it looks like a person, but much smaller than a person, a thin layer, looks like a piece of paper, and every household has it, as long as it is hung at the door, bright blue and yellow with a special appearance of the "new type of body detector", it not only decorates the door of the house, but also can do a full body examination for people who walk by, if you are not sick, then it will show a green light;If you have a fever or a cold, the "body detector" will detect your **, and show a red light warning and show **method. If it is a serious condition, the red light will flash one by one, and find out**, display**method and things to pay attention to, and print out the **method and things to pay attention to. The patients who have been treated by this kind of machine are all cured, and there is no need to go to the hospital, which can better solve the problem of difficult and expensive medical treatment for farmers, and reduce the burden on farmers' lives

If you think about it, I think nature will give you a lot of inspiration.

People say that the grass is very weak. Yes, it is very inconspicuous, weak and short. It's not as delicate and eye-catching as colorful flowersThere is no burly body like a towering tree, and he can't stretch his hands to the sky to attract people's attention;But it has a tenacious vitality.

I love it!Strong winds can blow off the branches of trees, and heavy rain can knock off the petals of flowers, but they can't take away the tender green grass. After the wind and rain, the bright green grass quickly returned to its former appearance, so peaceful and unscathed. It's so resilient, so strong.

The grass is a symbol of vitality. The grass is full of greenery, and it is a model of tenacious vitality. On the side of the road, on the beach, and at the bottom of the roof, you can see grass everywhere.

The blazing sun can't kill it, and the cold of the ice bones can't destroy it. A spring rain struck, and it came out of the ground with its head held high.

Xiaocao is a representative of green environmental protection. If there is no grass, there is no life on the earth; If there is no grass, the earth will become boring and boring; If there were no grass, there would be no life on the earth.

The green filial piety grass is endless, endless, a hundred, a thousand, ten thousand, a hundred million, ......Spread all over the lawn full of greenery. Where does this green come from? Oh!

It turned out that Xiaocao used his tenacious body to decorate the boring and monotonous earth so vividly and beautifully! The lawn is a place for people to rest, for people to cool off, or for children to play to their heart's content! Whenever you lie on the grass, you feel very comfortable.

Xiaocao, although you are weak, you will always be so strong! What you bring to people is comfort and comfort. We must learn from Xiaocao's spirit of perseverance and perseverance.

In the future, no matter what difficulties we encounter or what setbacks we suffer, we must be as brave and strong as grass! We must be like Xiaocao, dedicating our own piece of greenery to the society.
