In the vast solar system, there are a pair of "twin brothers". One day, the elder of the "twin brothers" - the earth's ozone layer disappeared. The iceberg melted and submerged the earth. The President of the United Nations had no choice but to move to another planet - Mars.

When people came to Mars, they saw that it was very dry. The scientific and technological personnel took out instruments and moved all the fresh water, high-rise buildings, and ancient buildings on the earth to Mars. However, people are becoming green.

Five hundred years later, BMW and Mercedes-Benz slashed their prices to one yuan for a car with a 4.0 exhaust, but they eventually went bankrupt. People use a small spacecraft that uses carbon dioxide as power and exhales oxygen. No more lead poisoning, kids chasing the spacecraft to get oxygen! The President of the United Nations thought that the destruction of the earth was caused by people's deforestation, so he set the day of relocation as Arbor Day. And let each person plant 5 trees with his hands to make up for his mistakes. The elderly, children and young people were very happy when they heard it. You may ask why?

The President of the United Nations has requested that 999.9 million tons of fresh water be created in one day. At this time, scientist Wang Yiyuan thought of a way to use a comet collector to attract a small part of the comets. Sure enough, in less than a second, there were 100 billion tons of water on Mars, and people drank the water in large gulps. . From then on, this great scientist will always be remembered in people's hearts.

Ah, where will people go after Mars dies? !

The future world "Get up quickly, get up quickly!" I opened my eyes and fell asleep. With hazy eyes, I told the robot Lele I had just created: "Lele, pour me a cup of refreshing tea!" After a while, a cup of fragrant refreshing tea was placed in front of me, and I breathed Drink all the tea.

Lele pushed over the electromagnetic table (the electromagnetic table looks like an ordinary table on the surface, but if you put the pot on it, you can cook rice in a while. If you put your hand on it, it will not get hot at all.

) After the rice was cooked, I pressed the green button on the deformed chopsticks, and the chopsticks turned into a small spoon and fork.

While I was eating, I asked Lele to bring me ultra-thin warm clothes.

After eating, I took a solar car to school.

On the way, I remembered that I didn’t bring any water.

It doesn’t matter, there are automatic drink machines on both sides of the road.

I took two cents and put them into the coin hole, and held a water cup to the drinking spout. I like to drink cantaloupe juice the most. I pressed the button with cantaloupe juice printed on it, and the drinking spout immediately flowed out. Sweet and delicious cantaloupe juice.

I finished drinking and continued to drive to school in the car.

Our school is in heaven.

When I arrived at the airport, many people were buying passes for the sky.

Some people buy it to go to the moon, and some people buy it to go to Mars. Our school is built on Mercury, so I bought a pass to Mercury.

I was flying while listening to the radio: "China has developed a new ultra-small computer, only as big as an eraser.

There is no pollution on the earth. People put garbage If you pour it into a specially designed well, it will turn into natural gas; another 20 mountaineering enthusiasts from China have climbed Mount Everest..." Before I knew it, I had arrived at the school on Mercury.

When I entered the classroom, my classmates were already in class. I didn’t need to shout a report, so I sat on the crystal chair.

The robot teacher uses a computer to teach us. There is no need to pay tuition, no exams, and no homework to go to school here. How easy it is! How beautiful the future world is. I know that the world will definitely develop into what I imagined! What is there on Mars? Essay of more than 300 words

1. The orange-red appearance is due to the hematite (iron oxide) on the surface.

Mars is basically a desert planet, with sand dunes and gravels all over the surface, and no stable liquid water.

The atmosphere dominated by carbon dioxide is thin and cold, with sand and dust suspended in it. Dust storms often occur every year.

Both poles of Mars have polar caps composed of water ice and dry ice, which wax and wane with the seasons.

2. There are many ancient craters on the surface of Mars.

However, there are also many recently formed valleys, ridges, hills and plains.

3. There have been floods on Mars, and there are also some small rivers on the ground, which clearly prove that many places have been eroded.

In the past, clean water existed on the surface of Mars, and there may even have been large lakes and oceans.

However, due to the small gravity of Mars and the water evaporating into gas, these things only existed for a short time, and it is estimated to be about four billion years ago.

4. In the early days of Mars, it was very similar to Earth.

Like Earth, nearly all the carbon dioxide on Mars is converted into carbon-containing rocks.

But without the movement of Earth's plates, Mars cannot recycle carbon dioxide into its atmosphere to produce a significant greenhouse effect.

Therefore, even if you pull it to the same distance as Earth from the sun, the temperature on the surface of Mars is still much cooler than that on Earth.

5. Mars’ thin atmosphere is mainly composed of remaining carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and trace amounts of oxygen (0.15% ) and water vapor (0.03%).

6. The poles of Mars are permanently covered by solid carbon dioxide (dry ice).

The structure of this ice cover is laminated. It is formed by alternately superimposing layers of ice and changing carbon dioxide layers.

7. The surface of Mars is rusty red. Scientists know from the soil of Mars that Mars has experienced floods. It may be because of this flood that the advanced life on Mars perished. Then there are some low-intelligent creatures left on Mars, so there are no highly intelligent creatures on Mars. "Encountered an Alien" essay of 350 words

The weather is good today. The sun is shining all day long, and there is a gentle breeze at night. The sky is filled with twinkling stars. I am lying down Looking at the stars on the grass, an unusual feeling came to my mind. Maybe there are people in the vast space looking at the stars like me, I thought.

I vaguely saw an oval hidden behind the light curtain. Shaped object, like made of metal. Am I dreaming? I asked myself. Without allowing me to think too much, a white light, cone-shaped, was projected from below the strange object, shining on the grass in front of me. From the light source, two human-shaped objects floated down. After falling to the ground Only then did I see that they were indeed two people. They looked very similar to us. Maybe newborn calves are not afraid of tigers. This completely aroused my curiosity. I mustered up the courage to take a few steps forward to get a better look. After I took a few steps, the light disappeared, leaving two people standing on the ground looking at me with smiles. I unconsciously took a few steps back.

"You don't need to be afraid, we won't hurt you." The female alien said that her voice was very pleasant, as if it could soothe people's hearts, and I calmed down. Come down and ask, "Are you really aliens?" "I admit that this question is stupid, but I could only think of this at the time. "Yes," the female alien said. In the next contact, they told me that they had been paying attention to our earth a long time ago, and they had also been paying attention to our earth at the appropriate time. They have helped us at times, and they have also contacted others before contacting me. The reason why they came to the earth is to advise us to take good care of the environment, give up war and killing, and pursue spiritual liberation. This is in line with the rules of the development of the universe, otherwise our Civilization will perish sooner or later. It didn't take long for them to leave, just as they came. Before leaving, they said that when we truly achieve peace, they will formally contact us and include us in the big family of the universe.

In the evening, I was the last one to leave the classroom.

As soon as I walked out of the playground, I saw a spaceship the size of a grape coming towards me from a distance.

The playground was filled with light, and the dazzling light emitted from the spacecraft made it difficult for me to open my eyes.

The spacecraft gradually descended and landed steadily in front of me. A letter written in Martian script floated out from it. When I held it in my hand, the words on the letter changed instantly. Became Chinese.

The letter read: "Hello, I come from the distant Mars. This time, I want to invite you to Mars as a guest.

One day in 2050, I took the "Explorer 1" and arrived Mars.

Under the fiery red sky, I walked out of the hatch and started my "one-day trip to Mars."

As soon as I stepped out of the hatch, a large number of intelligent Martian creatures came toward me, speaking "Martian language".

I couldn't understand a word, so I pulled out the "Mars Translator" from my pocket.

After setting the text content, you can translate "Martian".

The text was displayed on the screen. It turned out that the aliens were saying: "Hello! Hello! Welcome to the "Mars Zoo". This is the ticket office. Please pay!" It turns out that I The spacecraft stopped in front of the "Mars Zoo", and I decided to go in and have a look.

Walking into the "zoo", I saw many "animals" on Mars, including things with long noses and short rabbit-like tails. The tour guide told me that they were called "proboscis rabbits"; There is something with round ears and eight legs. The tour guide said this is called an "eight-legged monster" and it is very rare! After playing for two hours, my stomach growled, so I went to a restaurant to try "Mars delicacies".

The dishes here look weird: round, square, cylindrical, conical... I ordered one dish and one soup to see how it tasted.

"Ah, it's so delicious!" I couldn't help shouting, and then I ate it all hungrily.

After eating, I patted my bulging belly and bought another "Mars Cuisine Cooking Recipe", hoping to take it back to Earth to study "Mars Cuisine".

Later, I came to the largest "park" on Mars to visit the landscape on Mars.

Under the leadership of the robot tour guide, I came to a specially opened "Mars Text Lecture Hall" in a park.

This place welcomes people from other planets to learn the "Language of Fire", and the alien teachers there are also very docile.

I listened to a class and thought it was pretty good, so I left my robot pet "Little Dudu" here and let him learn "Fire Language".

After the dance ended, warm applause broke out, and many people cheered.

..."Oh, it's already midnight!" I shouted, "It's time for me to go back to Earth!" As I said that, I commented from the Bonfire Party Famous Teacher: It seems that after this article, teachers also have to I admire the young author's unbridled imagination, and through this article, he showed readers the interesting and dangerous experiences on Mars.

As far as the content of the article is concerned, the author mainly talks about the protagonist’s strange experience on Mars and the bonfire parties full of warm scenes. It seems that the author had a great time on Mars. Very good.

However, the teacher felt that this article was not finished. The end of the article was a bit rushed and it felt like it was not finished.

I hope the young author will pay attention to it in the future. A 400-word essay on what is on Mars

Nali also listened carefully.

"By the way, let me take you to see our base!" So Han Xin and Na Li went to see the base together.

"This is our power commander. Without it, our planet would have no electricity.

This is a golden wedding ring. If there is a cosmic meteorite, he will jump up and tie it to the meteorite. Stop, throw it aside..." Nali suddenly asked anxiously: "By the way, have you ever thrown a comet with a rope?" "Yes, by the way, why are you asking?" "Have you ever shaken Halley's Comet?

Life on Mars In the vast solar system, there are a pair of "twin brothers" Mars and Earth.

One day the elder of the "twin brothers" - the earth's ozone layer disappeared.

The iceberg melted and submerged the earth. People moved to Mars, the second child of the "twin brother", by spacecraft.

Mars has Antarctica and North Pole, mountains, canyons, white clouds, dust storms and tornadoes. Just like Earth, people are quite adaptable. There are also many dry river beds on Mars, some of which are even thicker than those on Earth. The Amazon River is still long.

There is no water on Mars, so what is the use of dry river beds? People thought that the original water on Mars was either in minerals or inside Mars, so scientists drilled the surface and finally spewed out delicious tap water, filling the entire river. With water, people could Build a house and live.

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

Houses on Mars are very interesting. Scientists flew small planes into space and collected a large number of meteorites to build houses. They fixed the houses with ropes to prevent them from flying into space.

The houses that people build are no less than those made of bricks on earth, with more complete styles and types, and they are more solid: they are not afraid of fire, water, earthquakes, or attacks.

If a meteorite hits Mars, all houses will activate rebound devices to bounce the meteorite back.

Every home 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 should I do? Scientists took a large amount of magma from the ground and poured it into the bottom of the house.

It can automatically adjust. If it is hot, take out some; if it is cold, put more.

It is also very interesting for us to go to and from school every day. When we go to school, we jump to the school gate with a slight push of our feet. After school, we only jump two meters with a strong push of our feet. This is because the buoyancy in the morning is very strong. It's big, so you can jump a long distance with just a push of your foot. The buoyancy at night is very small, so you can jump a few meters with just a push, which is very difficult.

It’s also very interesting at night. On Earth, it was very hot when sleeping. But on Mars, not only is it very cool, but you can also fly in a small plane and go to space to see the stars and the moon. It’s very exciting. beauty.

Late at night, people’s houses made of meteorites will naturally glow and be colorful. I lie on the energy bed made of meteorites and watch the miniature TV made of nanotechnology. I no longer have to do homework. Our The homework is an experiment. Human beings must start from primary school students and learn to make full use of Mars resources.

Wow, what a sense of accomplishment! People have gradually become familiar with Mars and no longer miss the Earth. Instead, they are thinking about how to protect Mars so that it no longer lacks resources like the Earth.

...

Going hiking and hiking in spring is a good choice. You have rarely exercised all winter, so it’s time to stretch your muscles.

Today I am going to climb Xiangshan Mountain, and I am beaming with joy.

Arriving at the foot of Xiangshan Mountain, wow, this mountain is so high! I was so happy and excited that I wanted to climb up all at once.

I rushed forward quickly, trotting all the way, running and running, beads of sweat falling down! I'm so tired that I can't even breathe! I sat down on a small chair by the roadside and rested for a while.

I think: A man cannot be afraid of difficulties.

After a while, I felt a little more energetic, so I started running again and rushed to the top of the mountain. I was the first to reach the top of the mountain. I forgot about fatigue and thirst. Jumped up.

My clothes were soaked! I touched the sweat on my head. After a while, my father reached the top of the mountain and I smiled.

The scenery here is so beautiful, and the Fragrant Hills in spring are also unique!
