On _, I arrived by time machine 1000 years later. In the future world, science will be more developed. Of course, science is simple and beautiful, pure and noble. Since ancient times, people have made unremitting efforts with their own intelligence and wisdom, and have made progress one after another in science, which has continuously improved the scientific level and integrated science and technology into our lives.
From the previous black-and-white TV to the current big-screen color TV; From the beginning there were no electronic products, to the present rice cookers, microwave ovens, hair dryers and so on.
Take the current mobile phone for example, almost everyone has one, and even some children have their own mobile phones or tablets, but I think the function of mobile phones is not strong enough. 1000 years later, everyone's home will be intelligent and mechanized. These household appliances will have a prime minister-mobile phone, which is like a smart housekeeper. At 6: 40 in the morning, he will organize electric stewing and cooking; At half past seven, the alarm clock rang; After waking up, you can have a delicious breakfast as long as you walk to the table; After you go out to work or go to school, washing dishes will automatically wash dishes; On the road, people's means of transportation on the road is no longer a car, but everyone carries a backpack aircraft. In the street, many animals swaggered on the ground, but someone passed by and touched their heads. Now, people's pets can also support tigers and lions. When you adopt them, you will give them a special liquid, make them mutate, and make these fierce animals that people were afraid to keep before become very docile.
When I get to school, the school is made of special materials; The classroom is built with artificial intelligence, and students' brains can copy knowledge directly from books, so the exam is easier.
At this time, at the moment when the bell rang, I was pulled back to reality, and it was 1, April 20_. It seems that dream and reality are both "April Fool's Day"!

June 10 is a lucky day. One day, an activity was held, and 100 out of 3.4 billion people chose to travel to the moon. I really won the prize.
Only a handful of people can go to the moon, only scientists, researchers and repairmen. I got up early and went to the launch center. I looked up and said, my god, the rocket is so wide and so high, like a pillar in the sky. This is a dragon about to take off. We soon boarded the rocket.
"Ten, nine, eight ..." My heart is beating fast. "Three, two, one, ignite!" The dragon made a deafening roar and went straight into the blue sky. After a while, the rocket became faster and faster, and the earth became smaller and smaller. The rocket began to fly around the earth, using the gravity of the earth to reach the fastest speed with the least fuel. We also enjoyed the beautiful earth by the way.
Then there was a loud noise, and the last stage rocket successfully separated and we flew to the moon. More than an hour later, our first stop, the space station, arrived, where we rested and refueled. It is said that there are 10,000 people living above, the space station is too big, the air is so fresh, and there are artificial clouds. Living in it is very comfortable and not depressing at all, just like a small country, but unfortunately we set off again soon.
Being close to the moon is so bright and spectacular. However, compared with the earth, it is so deep, lifeless, so lonely and shocking. The roar of the spaceship resounded through the earth, and here we are. After entering the base, we can take off our protective clothing. The researchers warmly received us and gave us a detailed introduction to the base. In the future, we will set up a launch center on the moon and fly to Mars.
The most interesting thing is to go to the surface of the moon. When you drive a lunar rover to a flat open space, you can jump as high as a floor and easily surpass the world champion. You can also grow vegetables in the greenhouse, eat moon food and space food.
Soon, we should leave. I look back at the moon. Soon, the trip to the moon was over.

The history of mankind is constantly developing, especially in the past twenty years, science has developed rapidly. Day and night, high-rise buildings rise from the ground and subway lines are all over the city ... but even if the technology is so developed now, it is not omnipotent. History is also very important to us. We should be familiar with ancient things and understand all aspects of knowledge and events, which will be more helpful to our development.
However, history is not easy to restore, and there are many doubts and changes in history, which makes it difficult to think, seriously affecting the exploration of ancient civilization. At this time, all these problems will be solved as long as there is a time machine. If there is a time machine, the world will change greatly.
Of course, the role of the time machine is not only to understand history. In education, time machine also plays a great role. People can go back to ancient times and learn about extinct creatures and the origin of various elements and minerals. Let us have a deeper understanding of biology and chemistry. You can use them better and more correctly. Popularize this knowledge more generally.
More importantly, the time machine is also very helpful to personal safety. For some unsolved cases in history, we can use the time machine to find the clues of interruption (destruction) and solve the case. For new cases, we can also better understand the case and even find and catch the murderer. In this way, more lawbreakers have been brought to justice, and our public security has improved a lot. You don't have to be always wary of strangers.
This technology has also promoted the progress of peers! We can go back to the past and get some experiments that scientists could not do because of the constraints at that time. We can also make new inventions. You can also know what you are doing and what you will do in the future, so that you can work harder in this field and make your future better.
Every coin has its two sides. We can use a time machine to go back and kill enemies, even competitors and people we don't like. Because the time range is very large and boundless. Therefore, the government's control over lawbreakers has been seriously reduced, and the number of lawbreakers among citizens has increased, causing panic and making citizens gradually oppose the government and fall into chaos.
There is more than one disadvantage. For example, in Liu's article Ocean of Dreams, people entered the era of machine cradle. At that time, we had the most advanced machines and software in the universe, but no one could use them. When the earth's energy is exhausted, we can only wander in the universe, waiting for death.
Science is always a double-edged sword. Ships are means of transportation, but they have created weapons such as aircraft carriers and submarines. Nuclear energy is a powerful energy source, which can reduce the "burden" of oil, but it has killed many people! Such an example is never rare. I just hope that such an invention is convenient for the people, not a "killing weapon".

"Hey, I didn't recite the text and was scolded by the teacher." A sixth-grade pupil named Han Han sighed. "If only I had a super brain, I could copy all my knowledge!"
The next day, on the way to school, Xiong Haizi suddenly remembered that the text assigned by the teacher yesterday had not been memorized, and his heart became cold unconsciously. At this time, he found a small advertisement on the wall, which read "Chaonao No.1, you deserve it" with the address written on it. He went to the place mentioned in the advertisement and found nothing except an unmanned vending machine. Bear, he invested one hundred yuan. It was strange, but I went to school without thinking much.
When he got to school, he found that the teacher was memorizing, and he was very flustered. He started cramming, but he found that he knew it by heart after only reading it once. "Xiong Haizi, please recite the text" Serving the People "."The teacher shouted. But Xiong Haizi didn't panic at all, and his heart was as steady as Mount Tai. The student behind him pulled his clothes and sneered, "You're finished! Haha! " I saw Xiong Haizi stepping onto the platform with confident steps and reciting the whole text word for word. The teacher's mouth turned into an "O" shape in surprise, and even the Chinese class representative gave him a thumbs-up sign, not to mention the table at the back. The teacher praised him and told everyone to learn from Xiong Haizi. He thought, this must be the function of this earphone. It's really cool!
Later, he read the four books, the Five Classics, encyclopedias and other books, participated in various competitions and won the championship again and again, only to find that his head became bigger and his body was thin until he fainted in the final of a global encyclopedia competition!
When I woke up, I found myself lying in a hospital bed and asked my parents what was wrong. After learning that he was in shock because of excessive brain use, he immediately threw away the "Super Brain 1" and decided not to use it any more. From then on, he also worked hard and became a real top student.
Although technology is good, it can't make us think seriously, so we must make good use of it, don't think about taking shortcuts with it, be down-to-earth and help us learn with technology!

The future school is amazing, please listen to me slowly for you.
As soon as you enter the classroom, you will find a big screen hanging on the wall instead of a blackboard. You will feel strange, haha! Don't be surprised, at that time, the blackboard has become a laid-off "old lady"! The future blackboards are all made of high-tech materials and cutting-edge technology, which is harmless to human body. It integrates the information superhighway and multimedia, and becomes a veritable first helper for teachers!
Ok, here are the desks and chairs in the future classroom. They have a monitoring function, which can detect every student's bad habits in the learning process, such as desertion, whispering, cheating in exams and so on. These behaviors that are not conducive to learning will be transmitted from desks and chairs to the teacher's blackboard, and then the blackboard will send back the teacher's criticism and instructions to urge students to correct them in time.
Not only the classroom is amazing, but also the outdoor design is amazing. You see, there is an anti-trampling machine that can give out a "beep" alarm sound on the green grass, and there is a humanized temperature regulating device on the playground to prevent students from catching a cold due to carelessness during sports. There are countless facilities like this.
Of course, this future school is only imaginary now, but in the future with more advanced technology, I believe there will be such a school.

One hundred million years later, the earth suddenly exploded. As the most famous scientist at that time, I have noticed this. So as early as a few months ago, I let humans escape in the spaceship I invented.
Finally, we fled to Mars, which is more suitable for human survival. However, the temperature of Mars is minus 23℃ and the atmosphere is very thin. How can we survive in such an environment?
However, as the most famous scientist, I can't beat such a small thing. I want to use the high technology I invented on earth before, and people around me are surprised to ask me, "What high technology is this?" I said, it's an amplifier. The principle of the amplifier is to make what you want on a small piece of paper by pressing the zoom button. This thing can be enlarged! This saves time and material! And then I started doing it. First of all, I made a protective cover on the picture. Its function is to prevent the ultraviolet rays of the sun from hurting our skin. But people around me asked me, "Of course, human beings can't survive without water and food, so what do we eat and drink?" I said, "Don't worry, I'm ready!" Then I dropped a drop of water on the drawing, and in an instant, a freshwater river appeared not far away. Then I put the seeds cultivated by super cultivation technology into the soil, and in a short time, the buds sprouted everywhere. At this time, people around you are relieved and think they can live like this. But one person asked a question: "Food and drink are all solved, but where do we live?" Obviously, there is no space on land, so I decided to move underground. I used four-dimensional space technology to build a four-dimensional space underground, so that people can live underground.
Then ten years later, people now don't have to wear spacesuits, and they are not afraid of getting sunburned when they go out. Dense forests have also grown on the land, and fresh water oceans have emerged. Since then, mankind has lived a happy life again.

"Ding-bell-bell-"I picked up the phone and only heard a familiar and unfamiliar voice on the phone: "Professor Muji, I haven't heard from you for weeks. I hope you are all right! " Professor Muji?
"I'm sorry, you seem to have the wrong number. I am not a professor of MUJI. " I was about to hang up when the man shouted, "Have you lost your memory? I am your good friend! " What! I used to be her good friend. Somehow, I suddenly fainted. ...
"Hey? Where is this? "
"Master, this is your home!"
"So ... who are you?"
"Master, I am the intelligent robot Huahua you created."
"Oh, then can you pour me a glass of orange juice?"
"Good master. By the way, master, when are you going to do your design? "
"ah? Then take me to see it! " I don't know what's new, so I'm particularly curious.
Huahua took me to the door of the studio, and she pointed politely inside with her hand: "Master, please come in." I crossed the threshold and looked at the messy studio. For an instant, I seem to remember everything!
I went to my desk and picked up the design draft, yes! This is the design draft, I want to finish my new design!
So, I went into the laboratory and began to develop a new type of water cup … an hour, a day, a month, a year … finally I finished this interesting invention!
"Recently, there is a famous new type of water cup in the market in Beijing, China, called' You decide the temperature'. Its price in the market is about 98 to 150 yuan. The color and pattern of this cup can be customized. Most importantly, it can change the temperature of water in the cup anytime and anywhere without charging, and even realize a series of functions of freezing or boiling water, which has also attracted the attention of many foreign citizens.
Hearing this, I turned off the TV. What I want to say is: I will try my best to design more products and do more things for China!

Now, because Grandpa Yuan Longping invented hybrid rice, the yield of rice is no longer a problem, but many people starve to death before the rice is ripe. This question has been puzzling everyone: how can plants grow fast and well?
On this day, I was thinking about this problem at home. My brother who lives next door told me that Sun, who lives in our community, invented an instrument that can make plants grow quickly! I immediately felt incredible after listening to it, and my eldest brother and I rushed to the door of Dr. Sun's house. As soon as I came in to say hello, I came straight to the point and said my purpose: to see the instruments that can make plants grow quickly. Dr. Sun saw my curious eyes and took them out with a smile. This instrument is very small, basically the size of an eraser.
I don't understand, can such a small thing play a role in accelerating growth? Dr. Sun looked at me puzzled and said, "Although it is so small, it can really play this role!" " After that, he led us to the nursery where he used to do experiments, dug a small pit, put some rice seeds in the pit, put the instrument not far from the seeds, then filled the pit, took out a remote control and gently pressed the switch on it. Soon the seeds turned into buds that came out of the ground, then green seedlings, and finally mature rice with full grains and golden color. My eldest brother and I were dumbfounded and asked why. Dr. Sun said with a smile: "In fact, this is ultrasonic, which has a strong stimulating effect on plants, allowing plants with a diameter of 300 meters to grow rapidly, and it will not affect the safety when eating, so you can eat with peace of mind." I thought after listening to it, great! Now everyone can eat their stomachs, and no one will lose their lives because of hunger. I quickly praised Dr. Sun's technology, and his invention benefited mankind. He touched my head and said, "As long as you love to observe, think hard and be brave in practice, you can be like me!" " "
Yes, science means observing more, thinking more and doing more, so that you can learn science well and benefit mankind.

I was born on Mars when I was six years old. There are often dry sandstorms on Mars, sometimes lasting for months. However, I am used to it, because my parents are astronauts and we often live on Mars.
One day, I saw on TV at the Mars base that Christmas was coming to earth.
"What is Christmas?" I asked my parents curiously.
"Christmas is a traditional festival in the West. At Christmas, it usually snows! " Mom said.
"But it never snows here!" I said.
"Our laboratory has a kind of polymer resin material-absorbent powder, which can make snow and keep plants moist." Dad said.
"Then use half of the absorbent powder to make snow, and the other half is buried under the saplings of the Christmas tree. It's the best of both worlds! " I said excitedly.
"Ok, let's get started!" Mom readily promised.
We took out absorbent powder and divided into two teams. Dad buried absorbent powder, and my mother and I made snow.
We pour out some absorbent powder and then pour in water. It expands bit by bit and gradually becomes like jelly. I was so impatient that I poured a whole glass of water at once, and all the powder was washed away by me. My mother told me to be patient, so I had to start over.
This time I waited patiently for it to turn into snow and continued to pour water bit by bit. Through my efforts, a cup of snowflake finally appeared in front of my eyes. I carefully poured the snow into the snow launcher, and I wanted to make more cups of artificial snow.
I repeated my previous work over and over again, and cups of snowflakes appeared in front of my eyes. Slowly, the transmitter of the transmitter was full, so we went to check Dad's "homework".
Dad has prepared the Christmas tree. We also invited Martians to see this wonderful scene. There was a loud bang, a group of "snowflakes" sprayed out, and the snowflakes fell in succession ... "It's snowing! It's snowing! " We cheered with excitement.
We hugged each other, gave each other gifts, danced and sang together ... This Christmas is of great significance, and I will never forget it.

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.
It all started in AD _. 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 trained with nine other astronauts: under the torture of high temperature resistance, low pressure, weightlessness and 720-degree gyro weightlessness sensor, I was training with Bai Jiaxing.
Later, I practiced with Bai Jiaxing and operated the spaceship. On June 65438+1 October1,our spaceship was selected as the launch vehicle.
At the end of the interview, after being persuaded by the commander-in-chief, we put on our spacesuits, boarded the plane 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 AT 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 filled with tears. ...
