800-word composition on science fiction imagination 2: If I were a tree

If I were a tree, it would be an ordinary tree.

I was planted in the soil. People water and fertilize me every day, listen to the beautiful songs of birds and take a nap while basking in the sun. How cozy it is!

Spring has come, and I have come out of the soft soil moistened by spring rain. I saw this vast world, this bustling city, this bustling city. I look forward to my future? Life? What a happy life it will be!

It is another spring, and I gradually stand up on this soil. I experienced the heat of summer, enjoyed the coolness of autumn and witnessed the beauty of winter. I gradually got to know every sanitation worker who went out early and returned late. I saw every office worker who tried to survive. I am used to the glitz of this city and the cruelty of this society.

Decades have passed, and it is another spring. I'm already a tree that covers the sky. I have strong branches envied by others, giving others a cool leaf. Sanitation workers have changed from batch to batch, and hardworking office workers are constantly changing. The air in this city is getting more and more turbid, and the high-rise buildings beside me block the sunshine that gives me vitality. I, just an ordinary street tree standing on the roadside, have all broken my hope for a better life in the future. I'm tired of the colorful and boring life in this city.

That spring, there was a rainstorm in this city, and many of my companions were injured by the wind and dying. At this time, I saw several people looking up at them with a sneer on their faces, and a sense of foreboding hung over my heart.

All my brothers and sisters were taken away by them, leaving none behind. There are only dead stumps left, and I am the only roadside tree on the whole road. I began to hate human beings, their ingratitude and cynical behavior. My body is covered with dust, my leaves turn yellow because there is no sunshine, and my branches become fragile because of inhaling too much exhaust gas. I have a hunch that I will end up like my companions.

Finally, I fell down. I was taken away by those people several years ago. They skillfully cut off my branches bit by bit and fell down bit by bit. I was dragged to a clearing by them and brought to a machine. I was cut into neat chips by that machine, and my life turned into sawdust and went with the wind.

Don't turn this into reality!

800-word composition on sci-fi imagination III: color quarrel

A long time ago, there was a fierce quarrel among various colors, and each color thought it was the most beautiful and unique. They are self-righteous and do not give in to each other.

Green boasted first: I am the color of life. Look at the countryside. Green fields, green trees and green grass ... because of me, the earth is alive! ?

Blue interrupted:? Don't talk big. You only see land. Why don't you go and see sea and the sky for a living? Most of the colors on the earth are blue, and the whole sky is my broad mind. ?

The orange could not help but speak: you are all so indifferent, only I represent warm colors and warmth. I am a symbol of vitality. Without me, you will see a cold world. ?

Huang giggled in a light tone: What are you? See the golden sun? It sheds golden sunshine, and everything has life! The world would be dark without me. ?

Red can't help it any longer: I am fire, blood, the color of life, the color of courage and the color of celebration! Look at the blood flowing in human and animal blood vessels. I gave them the energy to survive. You can't do anything without me! ?

Purple is the most stable one. He said slowly. I am a symbol of strength and an elegant color. Noble clothes or the crown of a monarch, which is less than me?

The quarrel between the color family continues. Suddenly, a burst of thunder resounded through the sky, and the colors huddled in the corner in fear, just leaning back for safety.

The rain spoke: stupid guy, don't you know? Each of you is unique, and only when you combine together will there be more and more beautiful colors. You will be more beautiful only if you unite, complement each other and cooperate with each other. ?

The colors looked at each other and seemed to understand something. Holding hands, they stood side by side in a row consciously, trying to arch their bodies into the sky to form a most beautiful rainbow.

Therefore, whenever rain washes the sky, there will be a rainbow across the sky. This is the beauty of the seven colors. It reminds everyone that it is most valuable to unite and integrate individual strength into the collective.
