2 1 century, people can see the development and innovation of science and technology everywhere. In the near future, people can travel in space by spaceship, make video calls or chat directly with their mobile phones or computers without writing letters. You don't have to cook, just use an electric rice cooker. After half an hour, delicious white rice can be presented on our dining table.
Following China's "Shenzhou-9" expedition into space and successfully docked with Tiangong-1, Shenzhou-10 was successfully launched at 5: 38 p.m. on June 1 1, 2000, and docked with Tiangong-1 again. Success again and again marks a country's technological development in the space field, adding a brilliant stroke to China's past space career.
Just yesterday, it was an exciting day. At 5: 38, with the countdown of scientific and technological personnel, the fire was ignited. A few seconds later, Shenzhou-10 rose to the sky with cheers from all corners of the country. I believe that at this moment, all people in China are happy and proud of China's space career.
Moreover, more than a month ago, our school also organized a model airplane production competition for young people's scientific and technological works. I also signed up for the competition. I think this is to show my scientific and technological ability and operate it by myself, so that we can have a strong interest in science and technology and study it.
So I signed up with my classmates, and my aerial photos began to be assembled. I'll assemble the hull first, tear off those signs and stick them on the model airplane, one by one, then cover the flags and assemble the parts. I tied three wires to the motor according to the instructions, red wire, yellow wire and black wire, and then tied the red wire and yellow wire to the switch. After tightening the motor and screws, put them on the seat, and then fix the motor with screws. Finally, I installed the battery, turned on the switch, and the motor began to turn. Finally, I put the upper and lower covers together.
Finally, on Tuesday, we have a model plane competition. Look at those people's model planes swimming in the water, they all deviated from the direction and got a few points. I thought to myself, "There are only two people out of ten, and my strength is not strong. It is not easy for me to get high marks. "
Finally, it was my turn. I squatted down and felt very nervous. My palms are sweating. Under the teacher's rhythmic "preparation", I turned on the switch of the model airplane and put it in the water. When the teacher said to start, I released my hand and let the model airplane go forward by itself. At first, the model plane was in the middle, but when it reached two thirds, it suddenly deviated from the channel and finally got 40 points.
This competition made me learn a lot of scientific knowledge, deepened my love for science and technology, and made me understand that only hands-on operation is practical.
Our country is gradually moving towards prosperity, and our science and technology are also gradually developing. Although our country can't compare with western developed countries. But I believe that as long as each of us realizes his dream, our country will become stronger.

Technology is really amazing, it is everywhere in our lives, and we can't live without it for a moment.
Students, when we are enjoying delicious food; When we are experiencing the wonderful and endless fun that computers bring us; When we eat fresh and sweet watermelon with relish in sunny spring; When we enjoy the coolness brought by the fan, do we think: What has brought such earth-shaking changes to our lives? What brings convenience and happiness to our life? It is science! It is a powerful scientific force that has changed us, changed our lives and changed the whole world!
In the 20th century, when talents came forth in large numbers, some great inventions and discoveries made people's lives change dramatically. Aircraft: a bridge to communicate with the world; Washing machine: liberating the labor force; Microwave oven: the liberator of women; Air conditioning: let the four seasons be like spring; Maglev train: a train that can "fly"; Zipper: seamless; Computers: make people's lives more colorful; Light bulb: illuminate the world; Green food: environmental protection, health and safety; Rice cooker: raw rice becomes cooked rice; Artificial seeds: can solve the food problem of human beings. ...
Technology is everywhere in our life, even in my home, there are endless technologies.
I have a curious heart since I was a child. I always want to find out what I don't understand, or what is novel. I remember once, when I was in "100,000 Why", my father told me about electricity and magnetism: "Electricity can produce magnetism. There is also a short story about this knowledge: 1820, Danish scientist Oster discovered in an experiment that electric energy produces magnetism. Because of this discovery, it opened the door for human beings to use electric energy on a large scale. " Then we did an experiment. My father and I first prepare a compass, a battery and a wire, then straighten the wire, remove the plastic at both ends of the wire to expose the wire, and then connect the wires at both ends of the wire to the positive and negative poles of the battery. Then we put the wire near the small compass. At this time, we observed that when the wire just approached the compass, the compass suddenly turned around and stopped. After cutting off the current, the compass is as quiet as a child who has just been taught. "This is the evidence that electricity can produce magnetism. It's amazing! " I sent a sigh with emotion.
Science and technology are developing rapidly, and life is trying to change. Science and technology are changing our lives. We live in an era of rapid development of science and technology, and we should be proud of it!
Science is a key to innovation, and it can only be opened if it is mastered reasonably.
Let's make life better with unlimited creativity!

If I were a scientist, first of all, I would invent an intelligent pencil. It has three functions: it can copy the journey to the west in one hour. Because it has a super chip inside, it can complete the task you gave it in the shortest time and the fastest speed. When you are tired, you can use it to play MP3 music to relax. In case you meet a bad guy, you can also use it as a small laser gun to deal with him. Because of its small size, it can be hidden and not easily found by bad people.
If I were a scientist, I would invent a universal remote control. It can not only remotely control all kinds of electrical appliances at home, but also remotely control cars, rollers, airplanes, and even remotely control spacecraft and various spacecraft!
If I were a scientist, I would invent a car called "Run Fast", which can reach 2000 kilometers per hour! It is powered by carbon dioxide and only needs to breathe twice a year/kloc-0. And the "waste gas" it emits is the oxygen that we humans and animals depend on for survival.
If I were a scientist, I would invent a spaceship and fly out of the Milky Way in only two years. This spaceship is not only fast, but also very safe.
How I want to grow up quickly! When I grow up, I can really grow up to be a scientist, and I can invent things that are beneficial to mankind. I know it's not enough to have an ideal, so I must study science and culture hard now, and only in this way can I realize my ideal.

Everyone has his own ideal. My ideal is to be a scientist and make more contributions to mankind!
If I were a scientist, I would invent a tool that can not only run on land, but also fly in the air at a speed of 1000 meters per second, and swim freely in the water at a speed of 2000 meters per minute!
If I were a scientist, I would invent a unique medicine that can cure all kinds of cancers and terminal diseases, relieve people's suffering, and even the recent SARS will be laid off!
If I were a scientist, I would invent a kind of soda water, which can make tired football players wake up immediately. That's because when people drink stimulants without toxic side effects, their mental cells will swell and their spirits will be better. Therefore, we players must::: Ha! He was full of energy and kicked the ball into the opponent's goal at once. Kick out of Asia and kick out the results.
If I were a scientist, I would invent a kind of clothes, which will change constantly according to the size, weather and color. That's because clothes are made of 100 kinds of raw materials. As long as the weather changes, clothes will shrink and thicken, and it is not easy to get into the wind. When the weather is hot, it will soon become shallow and thin. When the rice is dirty, it immediately becomes slippery, leaving no stains for a moment.
These are all if, if true, how beautiful our world will be, don't you think? ! Let's work together!

A loud noise woke Xiao Ming from his sweet sleep, yeah! Where is this? Why are you still at home? He barely opened his eyes and quietly recalled the dream he had just had.
He dreamed that he came to a mysterious ancient world where everyone had a pair of wings, which was very strange. Every household here has no doors, and people fly from the ground to sleep and rest. Suddenly his back hurts, and suddenly it doesn't hurt. He looked at his back. "ah!" He almost fainted himself, and he has a pair of wings on his back. He soon tried to fly by flapping his wings. Ah, he stood up and was able to fly freely in the sky by himself.
At noon, he felt very hungry, so he flew to a place full of delicious food and fruit. Who knows the people here are very kind, giving Xiaoming a lot of food, including chicken wings, hamburgers, sandwiches, coke, juice, and so on, and countless kinds of delicious food.
He flew to a place where people don't advocate learning and children can choose to go to school or not. So the people here are not very educated. Even the emperor's education is the cultural level of the sixth grade of primary school, and the lowest education is the cultural level of the first grade of primary school. Xiao Ming thinks he is a junior high school student, with higher education and deeper education, and certainly knows more than them. Xiaoming flew to the palace, where everything was splendid. Coincidentally, the old emperor was seriously ill and just died, so he had to choose a knowledgeable and literate person to inherit the throne. When Xiao Ming came, he also took part in the contest to choose the emperor. After layers of screening, Xiao Ming was elected as the emperor. He doesn't have to go to school or do his homework every day. He just marks in front of the monument and eats, drinks and plays.
But my mother shouted, "Xiaoming will be late if he doesn't get up!" " "He got up in a hurry, brushed his teeth, had breakfast, finished his book and went to school.
How can this be a dream? Xiao Ming muttered in his mind.

In 3082, I set foot on a barren and lifeless land, surrounded by piles of mecha wreckage and human bodies.
Four hours ago, a large-scale battle was about to break out. Karen, an alien leader, with a group of alien soldiers, intends to occupy the earth, and the remaining two billion earthlings also swear to defend the earth.
Dark clouds covered the sun, and the disappearance of light was the fuse of war, which made the inevitable war come ahead of time and both sides began to send troops. My teammates and I drove the spaceship quietly. Our task is to prevent enemy warships from launching neutron guns that will destroy the earth. Through the blackened atmosphere, the pollution of the earth has reached a position unsuitable for human survival, and all this is not a masterpiece of human beings? ! We came to Cullen's extraterrestrial territory. Unexpectedly, several aliens found us. We drew our swords and immediately dismembered these poor aliens. Moving on, I received a message from the earth on the way. There was a tsunami on the earth and hundreds of millions of people disappeared in the disaster. The situation is in jeopardy. Karma, people's long-term environmental pollution and ecological destruction are all bad things we have done. We are struggling to move forward, and the urgent task is to find and stop neutrons from bombarding the earth.
However, the surveyor showed that the neutron cannon had been started. If I need to unplug the socket within 50 seconds to stop the operation, I rushed to the enemy ship, broke one door at a time, and finally found the operation room. I can't tell which is the terrible socket I want. I tried to pull them out one by one ... finally, the cannon was fired and our place was wiped out. At that moment, my heart was surprisingly calm, and what was presented to me was a picture of people polluting the environment endlessly.
In the thick smoke, it seems like a small green bud breaks through the ground. Maybe this is the blessing of life.

In the blink of an eye, it reached the 25 th century. With the development of science, our life has been greatly improved.
In the 25 th century, houses have many shapes: love, candy, cars, bread ... all kinds of things that look like lying on the ground from a distance. Not only that, you don't need to fly or train when you want to travel. There will be a dimensional door in the air that can take you anywhere, and the house will become the size of a palm when you travel. The things in the house are also very special. The most important thing is TV. There is no remote control on TV, only three stations, namely: food station, study station and music station. When you are hungry, you should learn to cook like a food stand. The so-called "never too old to learn", TV will tell you what to learn according to your learning situation; When you are tired, turn on the music station. A wonderful concert will make you forget all your fatigue. By the way, as long as you say which channel you want in front of the TV, which channel will appear. But everyone should contribute to the society, and people with bad intentions will be discovered immediately, because everyone is born with round halo, black halo is the worst, colorful halo is the best, and people with black halo will be annoyed by others, so people with black halo will soon get rid of bad habits.
This is the 25th century. As long as we work hard, the twenty-fifth century will be better than now.

After many years, human beings invented the time machine, and I came to the "dinosaur era" with the "time machine".
As soon as I got off the time machine, I was surrounded by a hunting party composed of four "double-ridged dragons". I took out the cloaking device and became invisible. Four "double-ridged dragons" wandered around me for a short time and ran to the "chicken-like dragon" not far from me. "Double-ridged Dragon" killed "Like Phoenix Dragon" in a few moves.
Looking around, after there were no other carnivorous dinosaurs, they began to bite the body of "like a chicken dragon". I can't help feeling that this is the age of the jungle?
I started my jet pack, flew farther, and found Lei Long, Triceratops, Pachyrhinosaurus, ichthyosaurus and so on. At this time, I saw seven "Liang Long" surrounded by four "Kamakura Dragons", and five "Raptors" came in the distance. I think it will be interesting again. Those dinosaurs fought for about half an hour, and Kamakura Dragon won.
Once again, I came to the swamp in the dinosaur era and found that there were many devil frogs, giant pythons, pig crocodiles and emperor crocodiles. I think: if a dinosaur accidentally falls into the swamp, the end result will only be death.
Then, I went to the cave and the bottom of the sea respectively and found many things I had never seen before. After that. I took the "time machine" back to my "modern space".
Put ideal wings on science, and anything can be realized in the future.

When I opened my eyes, I was surprised to see this world full of science.
A pair of golden wings miraculously grew on my back, and I felt unspeakable happiness and curiosity when I saw this city.
Flying to the city with these golden wings, I suddenly felt how enjoyable it was to fly, but suddenly I landed and wanted to exercise. But just came down, only to find that most people on the ground are exercising in the "cloud gym" in the sky!
So I also spread my wings and flew to the "Cloud Gym". I see that every fitness customer is alone in a "cloud room", and there is a robot fitness coach guiding those customers to keep fit.
Where is my home?
Oh, it turns out that my home, no, everyone's home is on the middle floor. In the sky, there is a long ladder, which can be said to be a ladder. Opposite the school, there is only one school in a city, but they are divided into 32 schools, but their distance is not far. Just below their home, there are many rooms in a primary school.
Students, we go to the forest park once a week, because there are all kinds of trees, and there are machine commentators to guide us to know the types, characteristics and names of trees and breathe the fresh air there together.
This is a dream, just like a few years later. ...

Have you ever thought about what the future world will be like? If not, I'll tell you!
The future world is very beautiful and harmonious. Flowers and trees are everywhere. There are all kinds of birds living in the trees. The stream is crystal clear, and the fish swim around happily. People live in beautiful villas. Let me tell you a little secret. Some houses can fly. If we had a flying house, we wouldn't have to be afraid of earthquakes. Whenever there is an earthquake, our house will fly. If we want to travel, we don't have to spend money on train tickets or plane tickets, let alone stay in hotels. Best of all, people with mobility difficulties can go where they want to go at any time. There are no thieves in the street, and everyone is happy.
In the future, there will be electronic nannies at home, who can do many things for us, such as cooking, cleaning and studying ... especially for the elderly. When the old people feel lonely, the electronic nanny will also accompany them to chat and let them spend their old age safely. Students no longer have to carry heavy schoolbags, just take a paper e-book and open it with a click. The content of the textbook is colorful, animated and knowledgeable, which makes you fondle it.
Is this a wonderful world? Let's work together! As long as we protect the environment and study hard, such a world will surely come true.
