Self-report of snowflake
"Edelweiss, edelweiss, always meet you every morning. Small and white, pure and beautiful, always happy to see me ... "Hello everyone! With this wonderful music, I, Snowflake, met you.
I live in a big family of nature, and it's hard to tell what happened at home, but some of them are still very interesting. Take water vapor as an example. He and his friends travel every year. When they go to places where the temperature is below 0℃, they can't stand it. Everyone huddled together desperately to keep warm. This squeeze doesn't matter, but they can't be separated anymore, forming me-Little Snowflake.
My friends and I are flying and playing in the air, not to mention how happy we are. But just then, a boy of seven or eight years old grabbed me with his sleeve. I was so angry that I could only watch other friends travel. "ah! Come and see, everyone, the little snowflake is hexagonal. " He hurriedly called the other children. As soon as I listened to the music, I said, "What's the fuss? Our little snowflake is hexagonal. "
"Why is this?" The little boy kept scratching his head while talking to himself. Looking at his serious appearance, I just lost my temper and said loudly, "I'll tell you!" " In fact, my basic tissue is an ice embryo, and each ice embryo consists of five water molecules. Among them, four water molecules are at the top corner of a tetrahedron, and the other is at the center of the tetrahedron. Many ice embryos are interconnected to form ice crystals, and many ice crystals recombine to form me. So the reason why I am hexagonal is related to how water molecules combine into ice crystals.
The combination of ice embryos can only make me fat, but the parallel combination of ice embryos can make water molecules combine one by one and make me longer. I grew up in this left building and right building.
The combination of hexagons alone will definitely form a very symmetrical me. When I float in the air, I can run and jump. I won't run around my symmetry point, so as to ensure that I will always keep a hexagon when I grow up, and I won't' hump'. As for the type of hexagon, it is related to the different temperature and humidity conditions of the atmosphere when the partner is flying in the air. "The above is my structure and formation process. How's it going? Isn't it interesting?
"Ha ..." My eyelids are fighting again. I'm a little tired after talking for a long time. Do you mind getting some sleep? When you see glistening water drops on your sleeve, it means that I have fallen asleep, but don't wake me up. See you another day. Goodbye!
[Comment]: This paper describes the process of snowflake formation by self-description and personification. Hierarchical and vivid description. Especially the songs at the beginning of the article and the questions in the article make the article vivid, avoid straightforward narration and have certain characteristics.
However, why are ice crystals always hexagonal? It is difficult for readers to understand only by language if they have not learned relevant knowledge. Would it be better to attach illustrations? (This is also one of the commonly used means of explanation in scientific and technological discourse. )

The King of Animals-Tiger
When people mention the tiger, they think of its strong body, sharp claws and majestic appearance. Indeed, the tiger is called the king of beasts. It is a symbol of victory and strength. There are few tigers in the world. Of the nine kinds of tigers, four are extinct. There are only five kinds of tigers left, and some of them have only two digits left. But jaguars and Siberian tigers can still be found in the forest, and they are still the same. The coat color of the Siberian tiger is very beautiful, with "Wang" stripes on its forehead, and the long yellow hair mixed with black stripes looks very beautiful; Its strong limbs and intense eyes make it look dignified. The Siberian tiger is a carnivore, and its most powerful weapons are sharp claws and canine teeth. Its claws are more than ten centimeters long and can be extended and retracted freely, which is more advantageous than steel knives. Even cowhide can't help it. Dog teeth are 6 cm long and are indispensable "knives" for shredding prey; There are many sharp thorns on the tiger's tongue, which are suitable for hissing. Toe pads and palm pads are as soft as sponges, making the Northeast Tiger walk like a cat, silent, agile and elastic. Almost all kinds of tigers have these characteristics, which is their advantage in physical condition. Their predation ability is better than that of lions. They often make sudden attacks by lying still and sneaking around. Its whistling will frighten many animals to lie on the ground, but then they will be caught by beating, lifting and shearing. The tiger's jump is very powerful. It can jump seven meters and two meters. It can knock down a deer with one hand. Its tail is like an iron bar, which can break the waist and legs of animals with one chop. It also has sharp teeth and claws. When it meets a big guy like a cow, it jumps on the back of the cow from behind, grabs its head and neck, and pulls from the front. If you attack from the front, you will seize the throat and even bite and tear, and the cow can only be slaughtered. セセセセセセセセセセセセセセセセセセセセセ. Unlike lions, tigers usually come out for food at dusk, but their actions are very hidden. Except for the tigress and cubs, most tigers live alone and have obvious nesting areas. A tigress usually gives birth to a baby every two or three years, and a baby usually gives birth to two babies. With the decrease of forests, tigers, known as "forest protectors", not only can't protect the forests swallowed by human beings, but also their own survival is seriously threatened by environmental problems. At present, there are only over 3,000 tigers in China. Because of the great value and small number of tigers, it is difficult to see the majestic posture of the "king of the forest". At present, Northeast Tiger and South China Tiger have been listed as a kind of protected animals in China. I believe that through the unremitting efforts of people from all walks of life, future generations will surely see the majestic posture of the tiger, the king of beasts.
