Three essays on the secrets of nature for the second grade of primary school

Nature has its own way of survival and its instinctive secrets to avoid disasters.

It was during the summer, and I went camping at the beach with the tour guide. We suddenly saw a group of predatory birds extending their claws towards a young sea turtle.

Most people agree to extend a "helping hand" to the little turtle. But the guide's words made us quite angry. He said: "Never mind it!" In the end, the guide was convinced by us.

We picked up the turtle and put it into the sea. Our hats were pecked away by predatory birds. Later, we learned we had made a serious mistake, and the baby turtle turned out to be a "scout." When it encounters danger, it will retract its head. This is a red flag to other baby turtles in the nest. But we released the baby turtles back into the sea, so the other baby turtles received a wrong "safe" signal. Get them all out of the nest. This is when the little turtles came out one after another. Suddenly many predatory birds flew in the sky. The little turtles were picked up one by one by the predatory birds. Although we have worked hard to save dozens of them, there are still More than twenty were captured by predatory birds, which made us feel very guilty.

This incident tells us that we should not stop the behavior of animals, do not harm animals, and of course, we should not change or destroy the ecological environment at will. Otherwise, if you try to use human thinking to change the survival rules of animals, it will backfire.

What are the secrets in nature? Maybe you have asked many people, but they all have no answers. Then go explore it yourself and let nature tell you for itself.

When you explore the deep forest, you will find green towering ancient trees, low thorn-covered bushes, and soft and thick old fallen leaves. There are also delicate flowers parasitic on high branches, like colorful butterflies dancing in the breeze.

The trickling, cool stream beside the forest flows down the hillside with the fragrance of wild flowers. The monkeys were as naughty as children, and the oriole and many unknown birds sang happily together, like a chorus of nature. The children came to the creek and raced happily with the hares. When they were tired from running, they cuddled up with the small animals. They leaned on the sunny hillside and listened quietly to Grandma Feng's stories.

Are these all of nature? No - of course not!

When you put on a wetsuit and wander in the depths of the sea, you will find that the colorful corals are so amazing. In the gentle water waves, those colorful coral polyps that make you pity are swaying their slender bodies gently. Schools of colorful fish shuttle and chase among the corals, enjoying the rich treasures given by nature to the ocean.

There are also groups of smart and lively dolphins, happily spitting out strings of bubble rings to each other; parrot fish are tirelessly building sand castles; long, smooth sea The eel sleeps leisurely. And…and…. The boundless ocean embraces the huge biological chain given by nature and provides humans with abundant living energy.

When you take a plane and overlook the mysterious volcano from a high altitude, thousands of miles away, you will still feel the hot magma wrapped in huge energy, rolling down the mountains and seas, and cascading thousands of miles. threats. When a volcano erupts, it is the roar of the earth, the roar of nature!

What other mysteries are there in nature? It is waiting for us to continue exploring.

"The Secret of Nature" introduces you to the way of life of some plants and animals in nature and a lens from their daily life in the form of fairy tales. Let's learn more about nature.

In the book "Secrets of Nature", the ones I am most interested in are "Which flower has the sweetest honey?" and "In the Dark Forest".

"Which flower has sweeter honey?" is about: "One day, a fly and a butterfly discussed which flower's honey is sweeter? The fly said that the honey of bamboo cauliflower is the sweetest, and the butterfly said that the honey of dianthus flower is the sweetest. It was very sweet. Later, the fly brought the butterfly to the bamboo cauliflower. The butterfly said that she could only eat the food in the tall cup and would not eat the nectar with oil on the bottom. As she said this, the butterfly took the fly to the carnation flower. , but the fly's mouth is not as long as that of the butterfly, so it can't eat the nectar and flies back to eat the nectar of bamboo and cauliflower that it likes. "This article told me: everyone has his own taste, and the same is true in life. Each of us has his own taste. Unique lifestyle.

"In the Dark Forest" said: "A little kitten was brought to the villa by its owner, and saw the grass and the forest for the first time, and also saw plants and animals that had never been seen before in the forest. "This article made me know: In summer, the flowers in the dark forest are white because insects can see them; but animals are not necessarily white because their skins are of various colors. , so that you can hide in a place with the same color as your own skin to protect yourself or attack others.

I like this book very much, because it is a book that uses fairy tales to tell us the secrets of nature. There are many fairy tales in the book, which can tell us the secrets of nature.
