What is the ingredient of apocalypse?

Unconsciously, spring has come. This spring, the sunshine seems particularly bright and the wind is particularly soft.

One day, after a calligraphy class, I passed by Zhongliqiao Sports Square and saw many people flying kites. I couldn't help but stop to watch and see a colorful kite in the sky. Itching, I decided to give it a try.

With the guidance and help of my parents, my kite flies very fast. At first, I didn't dare to fly the kite very high, but let it fly very low, because there was only a thin and almost colorless line between me and the little kite, and I was afraid that the kite would fly away. At this time, all I can do is hold the spool tightly and the kite is flying at low altitude. I gradually put down my heart and began to pay off the line slowly. As the kite rose up and left me bit by bit, my heart hung up again, but the kite was still obedient and at my mercy, up and down. At this time, I found that this thin thread has completely bound the kite, and it can only be at my mercy. Now I even want to disconnect and let the kite fly freely.

The thread has been put to the bottom, and I feel a great force acting on the spool. Suddenly, the thread broke and the kite flew high. I breathed a sigh of relief and watched it go away, hoping it could fly freely in the sky, but somehow, the kite quickly rolled up in the sky and landed on the opposite sidewalk.

I thought if I got rid of the shackles, the kite would fly higher, but it fell. Perhaps, before it learns to fly, it can only be bound. In this process, it can try to fly higher gradually, but it must not follow one's inclinations.

Although I don't want to admit it, it is a fact after all, which makes me understand my parents' good intentions. I hoped they would let me fly, and now I even hope they can control me better, because today's bondage is to lay a solid foundation for tomorrow's freedom.

This is inspired by kites.

I hope I can fly freely in the sky in the near future.

Enlightenment of cactus

Ceng Meiling, Class 6, Fuyong Central Primary School, Baoan District, Guangdong Province (1)

I don't like growing flowers, and neither do my parents, but in order to green the environment, they bought some pots of flowers from the market and put them on the balcony. There is also a cactus that is not very eye-catching. Why is it called "cactus"? I don't know, maybe it's called "cactus" because its shape is different from human limbs.

Every morning, I water those flowers casually, because if I water too many flowers, I will die easily. I have also heard that cactus doesn't like drinking water very much, so it is watered every three or four days. My cactus is dark green and full of thorns, probably because it is not disturbed by the outside world, so there are many thorns on it. A cactus, a bit like the shape of a cucumber, is connected together, and some hold together like brothers and never part. Spring is coming, the grass is sprouting, the flowers are in full bloom, the rain is raining, and the fragrance is fragrant, which constitutes a beautiful and perfect spring scene. But who can notice cactus? It does not covet fame and fortune, and never gives in to difficulties. Sometimes I also find that there are countless cracks in the soil of cactus, and the soil is rough and dry, but it doesn't mind at all and still stands on a colorless ceramic basin made of soil. What is this for? In order to contribute to the world, add green to the world, absorb carbon dioxide, release fresh air and make the environment fresher. Although this flower is beautiful, it is too fragile and easily broken. Gradually, I fell in love with cactus unconsciously, because its noble quality has always attracted me, and I want to learn from it.

Enlightenment of fishing

There is a famous saying: "Persistence is success, and silence is victory". This fishing, I finally realized the meaning of this sentence.

On that occasion, my father said that he would go fishing in a friend's pond. I pestered my dad to take me there. My dad was very entangled and insisted on taking me.

Although the pond is not big, the water is deep. There are so many fish in it. Dad began to teach me to fish, and I said impatiently, "I know, I know!" " "

I threw the fishing rod back first, and then threw it forward hard, but I couldn't move it. I looked back and found that the hook had fallen on a tree not far away. I called my father and it took me a lot of effort to get out of trouble. Dad criticized me. I bowed my head guiltily.

This time, I can listen carefully! Put the hook with earthworm in the water first, and when the fishing rod moves, I'll lift it right away. Hey! I didn't see the shadow of the fish, but I ate half of my earthworm. I shouted angrily, "no fishing, no fishing, it's so difficult to catch a fish!" " "

Dad said softly, "Be patient when fishing. Before fishing like you, the fish will scare away. "

I listened to my father. I am very careful this time. I slowly put the hook into the water. After waiting for a long time, the fishing line still didn't move. I was so angry that I wanted to throw the fishing rod out, but I thought: no! As the ancients said, failure is the mother of success. I waited wholeheartedly again. For a long time, the fishing rod moved, and I was not in a hurry to take up the fishing line. Wait quietly until it's almost time, and suddenly say, yes, I caught a fish! Although it was only a small fish, I caught it. I shouted excitedly: "I caught a fish, I finally caught a fish, I succeeded!" " "

From fishing, I understand a truth: you must be patient in everything to succeed.

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!

& lt2> Humans have found some things from dragonflies and whales, but there are inventions in flies 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 movement 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!

It happened on a summer afternoon. The sun hangs high in the air like a big fireball, and there is no wind at all. The flowers and plants hung their heads listlessly and fell asleep. Even the asphalt road is soft, with deep wheel prints. I was walking on my way to school, wearing a hat, but my face was still sweaty. How I look forward to eating an ice cream to quench my thirst at this moment!

Walking, I saw a group of people buying ice cream in front. I felt thirsty and squeezed into the crowd to buy one. Take a bite of ice cream, wow!

It's so comfortable It is cold from head to toe. As soon as I threw the ice cream paper, it floated up and landed right outside the trash can. I ran to pick it up, and I thought, well, it's just an ice cream paper. It's nothing, so I keep going.

After a while, I came to a fork in the road and saw a five-or six-year-old boy running to his mother with an ice cream. As he ran, he shouted, "Mom, you're here!" He ran to his mother, with one hand holding the ice cream to her mouth and the other throwing the ice cream paper on the floor. His mother leaned down and picked up the ice cream paper and said, "Father Land loves cleanliness as much as you do. If you dirty his clothes, he will be angry. This environmental sanitation depends on all of us. There is a trash can over there. Mom will throw the ice cream paper into the box with you. " Say that finish, they walked to the front of the trash can and threw the ice cream paper in.

Looking at this scene, I blushed to the neck. The behavior, words and deeds of mother and son, like a stone, broke my inner peace. The ice cream in my mouth, somehow, is not cold at all. Not only that, I feel unusually hot, my face has nowhere to hide, my body has nowhere to hide, and my heart is like an overturned five-flavor bottle, bitter, sweet, sour and salty, and I can't tell what it tastes like. I looked at the back of the mother and son, and felt that I was missing something. I felt very small and couldn't lift my head. ...

In the following days, the weather continued to be hot, and waves of heat waves surrounded the city. As usual, when I am thirsty, I will buy an ice cream to resist the heat. I just stopped letting the ice cream paper fly with the wind, but carefully put it in the trash can. I frankly tasted the sweetness and coolness brought by ice cream.
