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.

"Ding-ding, ding-ding", what's that noise? This turned out to be the voice of a group of robots in the street. With the existence of robots, we humans can give him a lot of things to do, which is really convenient!
You see, in the middle of the road, a black-and-white robot is directing traffic in an orderly way, gesturing with its left hand and swinging with its right hand, which is in harmony with the color of the traffic lights. The people sitting in the car are relaxed because they are also driven by robots. Their driving skills are superior to those of human beings. I haven't had an accident for several years, and the main road is full of traffic and excitement.
As soon as people came in, a robot surrounded him and said in that gentle voice, "Hello, master, you are back!" " ! "People smile at it, and robots help it take off its shoes and deliver tea. There is also a robot, which is responsible for cleaning people's houses. Robots will take care of their owners. It turns on the warm air in the air conditioner, helps him change his pajamas, washes his face, and then takes out the ingredients from the refrigerator to prepare lunch. This technique is very skillful. After only two minutes, a pot of delicious food was served, and the host only needed to enjoy it at the table.
With robots, people's lives are more convenient, and some people who are incapable will not find suitable jobs, because most of the jobs are given to robots, in exchange for their sympathy, and they can only be eliminated by society.
There are robots because there are scientific and technological talents in society who can create robots, which is good for people's lives. Therefore, we should learn from now on and become the pillars of society!

One night, I was lying in bed dreaming. When I opened my eyes, I realized that I was in the morning of 2058.
There, I saw my alma mater At the school gate, it is no longer the school police on duty, but some robots. They are waving to me. In front of me is a teaching building. When I went in, there were no stairs, only elevators. On the fifth floor, I saw many spacious classrooms. I went into a classroom to have a look. The original book became a computer, and the students listened to the teacher with relish on the computer. But I've never met a teacher. I walked curiously to another small room. It turns out that all teachers have an air-conditioned room with a computer for lectures. At this moment, the teacher is giving a lecture to the students on the computer.
I walked out of the teaching building to have a look at the playground on the right. I see that the playground on the right has also undergone earth-shaking changes. There are no previous football fields, basketball courts, runways ... only flowers and trees, as well as those roses, peonies and lilies ... are particularly splendid, which can be described as a hundred flowers blooming and competing for each other. I can't help being intoxicated by the beautiful scenery. After coming to my senses, I asked the robot next to me inexplicably, "Why are there only flowers and trees on the playground?" Don't students have to run? It answered me solemnly: "Here is a button." After pressing it, the flowers and trees will disappear and automatically become a runway or something. "So, I safely pressed it, and it was exactly the same as what the robot said. I can't help feeling: "The future school is amazing. "
Suddenly, I got a knock on the head. It turned out that my mother was knocking on my head. I only heard her say to me angrily, "It's almost 7 o'clock, get up and go to school." It turns out that all this is a dream!

After work in the evening, Helen the robot brought hot coffee. "What TV program do you want to watch?" "Well, Phoenix Information!" As soon as she pointed to the wall, the host was projected in front of us.
Helen opened the electronic menu again. "Let's eat braised pork rice and hot and sour soup. I'm going to the movies after dinner. " "Wait a minute, dinner will be ready in three minutes." Helen said, "I have booked the movie tickets for you." What else do you want? " "Help me look at the traffic!" "The underground capsule system is under maintenance, the outdoor temperature is 20 degrees, and the air quality is excellent. It is recommended to travel by bike. It is estimated that 15 minutes will arrive at the destination! "
The cinema is as big as a basketball court. Just then, black music began, and a huge snow mountain rose in the middle of the cinema. Heavy snow, chill, snow-capped mountains shining silver. At the foot of the mountain is a colorful grassland. Suddenly, a group of Tibetan antelopes flew over the horizon, thousands of them, all dark and unstoppable, passing by the audience.
There was a loud noise, and the huge flying saucer hit the snowy mountain. In an instant, huge stones and flames hit the audience like an avalanche. I was in a cold sweat and exclaimed. ......
"Hey, it's time to get up. At 9 o'clock in the city hall, there will be a keynote speech on "Wings of the City"! " Helen is my artificial intelligence secretary. Her face is pure, her eyes are deep, and her white coat and light blue jeans exude youth and skill. This is the artificial intelligence that our institute is testing. Looks like a real person, with the IQ and ability of ordinary adults.
Looking out the window, it's a beautiful day. The whole city is lush and quiet, with only pedestrians and bicycles in twos and threes. Streets and communities are as beautiful as gardens. Urban air and ground have long been controlled, and citizens choose urban underground capsule system to travel.
Each family has one or two "city capsules", which are connected to the city's "cloud" intelligent system by using magnetic levitation technology and vacuum pipes, saying that your destination is unmanned, pollution-free, noise-free, safe and free, and the city can last no more than 2 minutes!
Haha, when the city has the wings of science, the future is no longer imagination. Welcome to 2040 Zhangjiakou Smart New City!

I have a wish since I was a child: I can talk to animals. I often think that if I can invent a language converter, I can easily talk to animals and make friends with them. At this moment, I am 60 years old, and finally realized this wish and invented an animal language converter. I designed it to look like a brooch, small and beautiful, and the sea is easy to carry.
On this day, I took my granddaughter Wenwen to the zoo to play. After coming to the zoo, I put on an animal language converter for Wenwen. As soon as she put it on, she told me in surprise: "grandma, I heard the monkey talking." He told his mother that his back was itchy and asked her to tickle him. " At this time, the mother monkey really began to scratch the little monkey's back. I kindly said to Wen Wen, "Wen Wen, you can still talk to the little monkey."
"Really, Grandma?" Wen Wen said excitedly, "Little monkey, you are so cute!" " The little monkey looked at it. It scratched its ear, scratched its cheek and said, "Thank you, but how can you talk to me?" Wenwen proudly said, "My grandmother invented the animal language converter, which allows me to talk to you." "This is really a good thing." The little monkey clapped his hands. Wenwen communicates with animals excitedly. When we came to the giraffe garden, Wenwen found a giraffe very depressed. Wen Wen asked the giraffe, "Giraffe, what's wrong with you?" "My neck hurts all day, but no one understands my pain." The animal language converter soon heard the giraffe's words. Wen Wen quickly told the breeder that the giraffe's neck hurt. They called the animal doctor to see the giraffe, and the giraffe was much more comfortable.
A breeder asked Wen Wen curiously, "Little friend, how do you understand giraffe's neck pain?" "I use the animal language converter invented by my grandmother, which can make people and animals understand each other's languages and realize the communication between animals and people."
I gave the animal language converter to the keeper when I left the zoo. I hope they can take better care of the animals there.
