Life on Mars: 450 words. Thank you.

In the vast solar system, there are a pair of "twin brothers" Mars and the earth. One day, the ozone layer of the earth, the eldest of the twin brothers, disappeared. The melting iceberg flooded the earth, and people moved to Mars, the second brother of the "twin brother", by spaceship.

There are South Pole and North Pole, high mountains and valleys, white clouds, sandstorms and tornadoes on Mars. Like the earth, people are quite adaptable. There are also many dry river beds on Mars, some of which are even longer than the Amazon River on Earth. There is no water on Mars. What's the use of a dry river bed? People thought of the original water of Mars, either in minerals or inside Mars, so scientists drilled holes in the surface and finally spouted delicious tap water, filling the whole river. With water, people can build houses and live.

Because Mars has no gravity, all the houses built are floating.

Houses on Mars are very interesting. Scientists flew into space in small planes and collected a large number of meteorites to build houses. They fixed the houses with ropes to prevent them from flying into space. There are no fewer houses built by people than those built by bricks on the earth. Their styles and types are more complete and more powerful: they are not afraid of fire, water pouring, earthquakes and attacks. If a meteorite hits Mars, all the houses will start the rebound device to bounce the meteorite back. Every family has a small plane. As long as aliens come, people can escape at the speed of light. Although the house is beautiful, Mars is very cold. What do we do? Scientists take a lot of magma from the ground and pour it into the bottom of the house. It can be automatically adjusted, and some will be taken out when it is hot; Put more if it's cold.

It is also interesting for us to go to school and leave school every day. At school, we jump to the school gate with a gentle push. After school, we jump two meters with powerful pedals. This is because the buoyancy is very strong in the morning, and we can jump far with a light pedal. At night, the buoyancy is very small, so it is difficult to jump a few meters with a hard pedal.

Evening is also very interesting. It used to be very hot when sleeping on the earth, but on Mars, it's not only cool, but also you can take a small plane to see the stars and the moon in space, which is very beautiful. In the middle of the night, houses built with meteorites will naturally glow and be colorful. I lay on an energy bed made of meteorites and watched a miniature TV made of nanotechnology. I don't have to do my homework anymore. Our homework is an experiment. Humans should learn to make full use of Mars resources from primary school students. Wow, what a sense of accomplishment!

People are becoming more and more familiar with Mars, and they are no longer nostalgic for the earth, but thinking about how to protect Mars, so that resources are no longer as scarce as the earth.
