Write some compositions like this:

In the mid-23rd century, the Chinese Academy of Sciences developed the first airship in history that can travel through time and space. One day, my friends and I were honored to fly a spaceship to visit the future world. Half an hour later, the spacecraft flew over the earth in the 23rd century. We opened our eyes hopefully and looked around. "That's impossible," we said in unison. The earth in front of us has turned black and white, and the source of life, the sun, has been extinguished. Not caring too much, we increased our power and drove into the earth. "Finally we're home" I saw a group of 4-headed, 4-meter-tall Earths and their assistants rushing toward us on a manned vehicle shaped like a dead tree and 30,000 times faster than our speed. In an instant Put a special protective film over us. We didn't understand what was going on. "Whew, swish, swish," a dust storm filled with black sand came overwhelmingly. The wind speed was almost 5 kilometers per second! If it weren't for this protective film, I'm afraid we would have been torn into pieces! After a while, the people from the future picked us up on their spaceship and sailed to their city. In order to prevent the city from being destroyed by wind and sand, people in the future specially made many special membranes covering tens of thousands of square kilometers, and then used super glue to stick them together. Enter the city. The buildings here are actually 1.2 million meters high, and the huge city buses have no exits. Just say "open or close" and the doors will open automatically. After a while, the presidential car took us to the presidential palace, and the servants brought us "rat stew" and "roasted ants". The servant quietly told us that these two dishes can only be enjoyed by people with special status. Upon further inquiry, it turns out that the earth's environment has been severely damaged. Only ants and rats have survived and are specially raised as food for the people on earth. It’s really hard for me to open my mouth in front of such “delicious food”. He had no choice but to quickly drive the spacecraft away. Please cherish our current earth and do not let future tragedies be a preview.
