In the blink of an eye, it has reached 2040, and the technology that can "call the wind and call the rain" has made people's lives change with each passing day. Smart phones have "evolved" into personal smart butlers, and smart home appliances are green and pollution-free ... What about intelligent transportation? Is it an electric vehicle that doesn't emit exhaust gas or a high-end maglev vehicle? Don't! Don't! Don't! Neither, but an intelligent wish transfiguration car.

Intelligent Wish Change Car-A car that can read the driver's wishes and change its shape accordingly. It can be turned into a bicycle, a flywheel car, a car, a maglev train and a light-speed plane at any time according to your wishes. ...

When you want to see the scenery leisurely, it will immediately become a bicycle, carrying you across lakes, fields, deserts, glaciers and grasslands, so that those beautiful scenery will be engraved in your mind.

When you want to pick up your children from school, it will become a flywheel car, which will carry you through the crowded crowd and let you pick up your children at the first time.

When you rush to work, it will become a car. It will accurately plan your route and move at the speed of 1000KM/h to ensure that you will never be late.

When you want to travel with your partner, it will become a maglev train, allowing you and your partner to enjoy a journey full of laughter and beauty.

When you want to meet a good friend in a foreign country, it will become a light-speed plane, take you across the sea of clouds, meet your good friend at the first time and spend a good time with your good friend.

When you want to be good friends with fish, it will become a fish-shaped diving boat, allowing you to shuttle through the fish, dance with the fish, keep company with beautiful corals and fight fierce sharks.

According to scientific speculation, the earth's resources will be exhausted in hundreds of years, global warming and sea level rise. If we don't move to other planets, the end of the world will come, and the consequences will be unimaginable.

When the earth is in trouble, everyone has a responsibility. As a new generation of astronomical scientists, I think hard day and night to prepare for the plan to transfer planets.

First of all, we need to find a planet rich in resources and suitable for living. But it takes decades or even hundreds of years for an ordinary spaceship to reach a planet. I developed the superluminal spacecraft, and it took me three years to transform the components of the spacecraft and invented the superluminal spacecraft that can accommodate 10,000 people. The superluminal spacecraft is a large spacecraft that is many times faster than the speed of light, and its speed can be adjusted, up to 50 million light-years per hour. I flew into space with super bread, visited hundreds of planets, made thousands of investigations, and finally found various resources on the 1 10 planet I visited.

The planet where I landed is located on the sixth planet in the Golden River system. Here, birds are singing and flowers are fragrant, the climate is warm and pleasant, and various resources are rich. The area is ten times that of the old earth, which is very suitable for human habitation. I was so happy that I learned about this planet at once. After calculation, the planet is 65.438+0 billion light years away from the Earth, and it takes only one day to drive a superluminal spacecraft. I reported to the earth and worked out a plan to transfer planets with other scientists.

On the first day of transferring the planet, people waited at the designated place. When they saw the FTL parked in the gymnasium, they all admired the development of science and technology. People began to move in turn. I set the speed of the ship to the fastest, and I can move a batch in two days. After more than a year of transfer, on the 569th day of the plan, all people were safely transferred to the planet.

Coming to a new planet, feeling the new sunshine, people started a new life, and I started a broader exploration of the universe.

Get up in the morning, pour a glass of milk and go to wash. After washing, I found that the milk was gone, and someone made breakfast for me. My parents are on a business trip, and I am the only one at home. Who did this?

Suddenly a white liquid flowed in front of me and immediately turned into a pair of hands. Obviously, they are my milk. I am curious. Before I knew it, it had turned into a face. He came up to me and said, nice to meet you. I am your milk.

I am hungry, too. I started eating before it was over. When I was full, I found it was gone. I looked at my watch: oops, I'm late. I grabbed my schoolbag and rushed out. I went downstairs and found a white car waiting for me at the door. We also turned into a small helicopter along the way. It didn't take ten minutes to get to school. There was no class that afternoon, and it was almost noon. I walked out of the school gate and found the car parked at the school gate again. We went home.

I found it reading the newspaper, and it was reading very fast, at an amazing speed. The most powerful thing is that when cooking, it washes vegetables, steamed rice, fried and cooked a lot, and the nutritious meal made is not only delicious, but also reasonable. It moves quickly, a delicious and rich meal is finished quickly, and the most important thing is that there is no helper. It also washed the dishes and checked my homework. Like me, it should have a rest.

I fell asleep and dreamed that I drove away in that car again.

When we came to the future, we saw a piece of green and blue, so people flew around in their own environmentally friendly spacecraft. When people walked, they floated in the air. Because the ground was full of flowers and lakes, people could not step on the ground, otherwise they would be caught by the police. At this time, the police are very developed, because all the people outside are robots, and only people are at the headquarters. So at this time, police casualties have been greatly reduced.

Let's talk about the house again At that time, houses were suspended in the air, because only flowers, lakes and small animals were allowed to stay on the ground. At that time, the materials used to build houses were very special, such as pressure resistance, waterproof, fire prevention, radiation protection, electric shock prevention and earthquake resistance. It can be said that it is the material for people to build houses and houses.

At that time, our medical technology was very, very advanced. At that time, the cloning technology in our country had reached the point where it could replace the internal organs of patients. By that time, almost everyone can live a long life. Because at that time, when our life is coming to an end, we can transplant a cloned heart, and then we can live a long life.

The most important thing in our future is environmental protection. Suppose I go shopping and spend five yuan, then I will plant five seedlings. In that case, I will not only buy things, but also protect the environment This is killing two birds with one stone. When you finish eating, the garbage bags left behind will be put into the recycling bin. When the garbage in this recycling box reaches a certain amount, it will become an exquisite decoration. So you don't have to reuse it again and again.

Our future may be a blueprint that can be changed at will, or it may be an unchangeable blueprint, but our future will certainly become very beautiful, very advanced and very civilized. Because the times will change, so will we humans. I believe that the future world must be a world beyond our imagination! It will last forever.

Ah, my long-awaited white wings have finally come out! It is a means of transportation in the 22nd century. As long as people wear it, they can fly freely in the blue blanks like birds.

White wings stretch freely, like butterfly wings; Retract, like a backpack.

We don't have to squeeze buses or drive private cars when we go out. As long as you tell Whitewing where they are going, its whole universe CPS positioning and navigation system will start to work. It will take you to your destination exactly. It has three speed modes for you to choose from: First, the Monkey King, with a speed of100km, is suitable for emergencies. For example, firefighters put out fires. Second, the pig eight quit type, per minute 10 km, suitable for office workers. Third, the Tang priest style is 5 kilometers per minute, suitable for the elderly and children.

If everyone uses white wings, will there be a traffic accident in the air that day? Of course not. Because they all have their own orbits. This invisible orbit is the earth's magnetic field. All the eight-color wings fly orderly in this big magnetic field. There are no traffic lights and no traffic police.

The most striking thing is that it is powered by carbon dioxide, and there is a special motor in the backpack. It can inhale carbon dioxide made by human beings, convert it into sugar, then into salt and finally into electricity. These complicated processes are all completed in an instant. Finally, the oxygen is discharged.

How about white wings? Isn't it amazing? I hope white wings can bring more comfort and convenience to our life.

I am a mermaid living in the depths of the sea. During the day, I play with other fish in the coral; At night, I will swim to the surface to enjoy the beautiful sunset.

I swam gracefully and freely in the evening sea. The setting sun dyed the place where the sea meets the sky warm orange, and the blue sea turned orange against the orange sky. The sparkling sea refracts the afterglow of the sunset into brilliant diamond light, dazzling! Occasionally a few seagulls fly by in the quiet air, and everything is so quiet and peaceful. At this time, under this scene, my tail that was out of the water overflowed with colorful brilliance, shining and burning people's eyes.

I thought I could do this every day until the end of my life and become a white and round pearl in a fairy clam, but ...

That night, I went to the seaside to play as usual. However, before swimming out of the sea, I was "hit" by a sour water wave, and the feeling of dizziness, nausea and vomiting suddenly surged up. To make matters worse, my skin suddenly itched and I broke out in a big rash. I rushed out of the waves and swam back to the bottom of the sea uncomfortable.

After returning home, the rash on my body not only didn't disappear, but became more and more itchy, and it hurt when I touched it. In desperation, my mother can only take me to the octopus clinic to find an octopus doctor. No sooner had we arrived at the door of the clinic than we heard sad voices coming in and out. At this time, I was surprised to find that almost all my uncles and aunts who came to see a doctor were like me, with red rashes all over their bodies. Some rubbed against the wall and groaned in pain; Some were so anxious that they wagged their tails and kept turning around in the clinic; The other children were so sad that they burst into tears. Uncle octopus is very busy these days.

From their conversation, I finally understood the reason for all this. It turns out that all this is caused by that race called human beings. They dumped a lot of domestic garbage into the sea, and sewage and wastewater were also discharged into the sea. Because the purification of seawater is not as fast as their pollution, the water quality of upper seawater is seriously deteriorated and stinks.

Since then, I have never been to the seaside or enjoyed the magnificent sunset. I can only hide at the bottom of the sea every day and pray to heaven: human, save us!

By 3569, the core energy of the sun had been exhausted. The sun began to expand, the sea level of the earth rose sharply, many tsunamis occurred in the coastal areas of various countries, and many countries surrounded by seawater were swallowed up by seawater. The countries of the earth held an emergency joint meeting and finally reached an understanding to release the artificial sun and "seal it up".

In order to prevent the sun from turning into a huge red star and devouring the solar system, the second decision was to launch millions of mustard seed space bags. What is this mustard space bag? It turns out that this is a new tool recently developed by scientists. In fact, this is the legendary "dry handbags", which can hold things billions of times larger than it. These millions of "mustard seed empty bags" will converge into a huge "mustard seed space" at a predetermined place, and the whole sun can be put in. No matter how the sun expands, it will never burst this bag.

The third and most important one is to use the space station in space to launch nano-robots, connecting the three planets of the moon, the earth and Mars with the bases on Mars, and establishing a huge channel. There is already a human testing ground on Mars. Then I began to prepare to emigrate from the earth to two planets.

Three months later, all three plans have been successfully completed, and the three planets have been surrounded by nanoparticles around Samsung, forming a second "atmosphere" and forming a solid protective wall.

Ten months later, human beings have been distributed throughout the galaxy, forming a huge galactic empire. At the same time, mankind has also sent a joint fleet composed of countries and tens of thousands of exploration robots to explore the outside world.

Battleships "Red Rainbow", "Paris" and "Huayang" in the joint fleet led the main fleet and also led 35 escort warships to form an advance fleet. Opened a magnificent journey of space exploration.

With the rapid development of industry, people's lives are becoming more and more comfortable and perfect at the moment. You see, there are computers on the internet, and cars are running all over the street; Wechat chat, taking photos, videos ... how convenient everything is on smart phones! And all this stems from the great achievements of high technology.

However, while high-tech products bring convenience to people, they also bring many negative effects. Watching TV for a long time will make you nearsighted, and the electromagnetic waves of the computer will radiate to the human body. Exhaust gas from cars and air conditioners will cause air pollution. I have seen the power of air pollution before, so I am deeply touched by its harm.

Not long ago, a strange thing happened just after my living room was renovated. Grandma, who has always been in good health, often complains of headaches, sneezing and crying from time to time, and taking medicine is of no help. I searched the Internet and finally found the "culprit". Originally, the decoration paint contains a lot of formaldehyde, which is the "invisible killer" of indoor pollution!

After seeing the harm of formaldehyde, I began to imagine how to solve this problem in my own mind. I want to invent a special multifunctional artificial tree, which is made of recyclable plastic PET and can be used for people to rest and enjoy the cool during the day. At night, it becomes a beautiful street lamp and a beautiful landscape of the city. The key is that solar photovoltaic cells are installed in the trunk to collect solar energy and provide energy for the air purification system. The leaves of artificial trees contain electronic components, which can not only absorb harmful substances such as carbon dioxide in the air, but also convert them into oxygen needed by human beings. Every artificial tree is an air purifier. They are like the most loyal environmental protection guards, creating a beautiful and fresh living environment for people.

Although this is only an idea at present, I believe that this wish will come true as long as I work hard. Only when high technology is in harmony with nature can it benefit mankind better.

The future classroom is full of wisdom and magic.

When you walk into the classroom, all the equipment will turn green in an instant. It feels very good, as soft as cotton. Green not only makes the eyes comfortable, but also drives away all the bad moods.

When you enter the classroom, the first thing you see is the blackboard, which consists of four electronic screens. There is a prominent blue button in the upper right corner. Don't underestimate it! Can play a big role. When the teacher is giving a lecture, if the words are small, you can press the button and the students will feel that the words are enlarged. If the word is still small, press it again, and the word will be enlarged again until it is the right size.

Looking up, I saw the beautiful, safe and gentle lamp at a glance. The lamp "lives" on the ribbon, and you must think: Why is the lamp on the ribbon? Isn't the light heavy? Let me tell you something! This kind of lamp is as big as a balloon and weighs about 20 grams. It is also very safe, and it will never leak electricity. Moreover, this lamp is charged by absorbing carbon dioxide in the classroom, which not only saves energy but also purifies the indoor air. Another feature of this kind of lamp is that the light it emits is soft and does not hurt the eyes at all.

The windows of the classroom in the future are much safer and more magical than today. The window is made of special transparent cotton, which not only won't break, but also can prevent myopia. Short-sighted students can recover their eyesight in less than a year as long as they look at such a window for ten minutes every day without surgery.

The desks and chairs in the classroom will be much more convenient in the future. This kind of desk and chair is amazing. As soon as students sit on it, they will involuntarily study hard, listen to the teacher carefully, and correct their writing posture, which can be said to kill two birds with one stone.

When entering and leaving the future classroom, you will also find the door much more convenient. Students don't need keys at all. We just need to scan the palm on the door. If there is our palmprint information in the database, the door will open automatically. Otherwise, an alarm will be issued.

The classroom of the future is desirable. Let's explore the wonders of science together, make progress together, and strive to build such a classroom when we grow up.

Looking at the people on both sides of foreign shipping ports, stepping on the solid earth, feeling the beauty of gravity, and looking at the familiar national flags on both sides, I can't help but burst into tears and kiss the earth under my feet. Everything is so familiar.

All this has to start from 220 1 year. At that time, as a mature space pilot, after half a year's selection, I was finally lucky enough to be selected as one of the candidate astronauts of the Silk Road, an extraterrestrial satellite. In the next month, I and nine other astronauts went through the devil's training: enduring high temperature, low pressure, weightlessness and 720-degree gyro weightlessness.

Later, I practiced with Bai Jiaxing and operated the spacecraft. In June 65438+10/October 1, 22065438, our spacecraft was selected as the launch vehicle.

After the interview, after being persuaded by the commander in chief, we put on our spacesuits, boarded the aircraft and sat in the fixed seats of the launch module, expecting to take off, but this was actually the beginning of the nightmare for the next nine years.

"10, 9, 8, 7, 6 ... 3, 2, 1- start." With a loud noise, a strong flame erupted from the bottom of the plane. After the earthquake, the plane slowly flew into the sky, as if being thrown into endless black asphalt.

Looking at the smaller and smaller earth, I feel yearning in my heart, but it is not too strong. After all, after seven days, we will come back, just like a kite being pulled. Will we go back anyway? But I didn't know that the kite string would be broken in seven days.

Seven days later, we started the automatic A.T. to return home. Suddenly, this hateful space junk crashed into the return cabin, and the heat insulation tile completely failed. We have to roam in space, and the only connection is wireless communication.

In the next nine years, Bai Jiaxing and I lost control of our emotions many times, but I didn't do anything extreme for a person's dignity.

On the last day of my nightmare, which is also the last day of nine years, I woke up and watched a white object getting closer and bigger. If I look carefully, isn't that "saving angels"? I woke up Bai Jiaxing excitedly, and we hugged each other tightly …

Two days later, one day after I came home, the reporter interviewed us: "Hello, how did you persist in these nine years?" I only replied: "It is my love for my motherland and my nostalgia for the earth."

Yes, nine years have passed and I am back. Looking at all this, my eyes are full of tears …

In 2058, human science and technology has developed into an unprecedented era. More and more high-tech products are filling people's lives and changing people's lives.

When she was a teenager, Lele was lucky enough to be the first volunteer to participate in super brain activities.

On a sunny day, Lele and other volunteers came to the institute of Dr. Li, Chinese Academy of Sciences. In a spacious and bright hall, Dr. Li slowly came to the waiting crowd. Lele stands out from the crowd today because he is wearing a particularly dazzling yellow coat. Don't underestimate this coat. It is a high-tech product: it can not only naturally adjust with the temperature to ensure the comfort of the owner, but also has the function of autonomous flight. Lele brought it here today.

I saw Dr. Li coming to the middle of the crowd, his eyes pointing to Lele in the crowd.

This little friend, can you answer me a few questions? Although Lele is handsome, learning this thing is his biggest headache. But in the face of everyone's eyes, Lele can only face the difficulties. Can you tell me which Tang Dynasty poet you like best? Tang Dynasty poet? I like Li Bai, Du Fu and Bai Juyi. This can't beat me, Lele thought.

Then can you recite a poem by Bai Juyi for everyone? The long grass is so lush that the withered grass will thicken the color of the grass every autumn and winter. Wildfire can't burn it out, but the spring breeze can revive it. Very well, Dr. Li went on to ask, can you tell me why it hails in summer? Lele shook his head. Can you tell me why the sky is blue? Lele shook his head again. That's all right, Dr. Li said. After I implant a' super brain' into you, these problems will be solved.

With that, Dr. Li gently raised his wrist, revealing something like a watch. Looking at everyone's puzzled eyes, Dr. Li told everyone that this is called a knowledge replicator. Then he put two connecting wires on his temples, and in less than a minute, the knowledge was copied to Lele's brain. At this time, the sound of copying and using came from the knowledge copying machine.

In order to let everyone see the magical effect of the knowledge copying machine, Dr. Li gave Lele a question this time. How do marine animals sleep? Why do morning glory always grow left-handed? What? Why are there so many asteroids in the solar system? What kind of rocket is the most powerful? Strange to say, Lele blurted out every answer and finally won warm applause from everyone.

After the experiment was successful, Dr. Li did the same experiment for other volunteers who came. Everyone's face is full of excitement and excitement.

All this can't help but make people feel that the development of science and technology has not only changed people's lives, but also made people believe that the earth's tomorrow will be better and better!
