If I were a scientist, I would invent shoes for the blind. As long as the blind man says "go where he wants to go", he will safely send the blind man to his destination.
If I were a scientist, I would invent an emotional tester. He looks like a magnifying glass. If you want to know the mood of others, look at them in the mirror. If it is the sun, it means you are happy. If it is cloudy, it will be troublesome; If the east rises and the west falls, it means that you are very anxious; If it's thunder and lightning, it's raining cats and dogs, which means that the mood is particularly bad; If the clouds are rolling and the storm is raging, it means that you are very sad.
If I were a scientist, I would invent a multifunctional car. If you go to bed late and don't have time to have breakfast, just say automatic navigation as soon as you get on the bus, and it will automatically turn on. I can make breakfast for you, too. If you want to say breakfast, it will prepare the tableware for eating, it will ask you what you want to eat, as long as you name the snacks you want to eat, it will make them for you. It also has the function of diving and flying!
If I were a scientist, I would invent. ...
It has been 20xx years now, and human science and technology have developed rapidly, and I have also become a famous scientist. I invented many things and applied them widely in my life. But I'm not satisfied. Now, I am working on what I have dreamed of owning since I was a child-flying machines.
Planes are very environmentally friendly, unlike cars that pollute the environment with exhaust gas. It uses the energy synthesized by carbon dioxide absorbed by itself and solar energy as energy to run. Unlike airplanes, airplanes can seat dozens or hundreds of people at a time. It can only sit one person at a time. It doesn't fly high, but it flies very fast, sometimes even faster than an airplane, and it is flexible and safe. If the road is crowded and the car can't move, but you learn to be late for work, the flying machine is your best choice. There is no need to squeeze people and cars on the ground. Enter where you want to go and the aircraft will walk.
Planes can also become robots to do housework. Take care of the children at home and go out to buy food. You can plant trees outdoors. This robot plants trees quickly and has a high survival rate! Put the water seedlings in a fixed mold and you can plant trees soon! There are many such robots in the desert, and the desert will soon become an oasis!
This is the plane and robot I invented!
Science and technology are the primary productive forces and play an important role in the development of human history. In human life, science and technology are widely used in various fields.
In agriculture, due to the application of science and technology, human beings have cultivated hybrid rice and transgenic fruits. So that the grain output is continuously improved and the quality is continuously optimized. Humans have also invented various seeders, fertilizers and harvesters. So that less and less manpower is invested in agriculture.
In medical treatment, due to the application of science and technology, people have invented various high-tech medical instruments and drugs, which can treat patients painlessly and prolong people's life.
In national defense, due to the application of science and technology, scientists from various countries have invented various scientific and technological weapons-missiles, fighter planes, radars and so on. They play an important role in safeguarding the territorial integrity of the country.
In life, due to the application of science and technology, we invented the telephone, television, computer, car and plane. So that we can go to heaven and get in touch with people thousands of miles away.
Technology is amazing! Scientists are so great!
On Sunday, I participated in the innovative modeling activity of 3D printing "Scientific Salad Sauce".
As soon as he entered the door to sign, a salesperson pointed to a row of things that looked a bit like piggy banks and said, "Scan the QR code and send one." Seeing a lot of people taking it, I asked my mother to sweep it, too.
The teacher who taught us this time is the manager of my shop. He asked us if coins would disappear, and asked us to design a coin classifier. Some people will answer, because now they all use Alipay to pay, and not much cash is used; Some brains are wide open, saying that the refraction of light can make coins disappear; Some people say no because our children need change. Finally, the teacher commented that coins will not disappear at present. They are stronger than paper money and are not easy to be damaged, so there is a great market demand.
The most wonderful thing is to draw a 3D model in the computer room. Click "Doctor's Hat", 1 change 2, click the ellipse, and change 25 to 26. Draw a circle on the middle graph, with 100* 100 change 150 in the upper right corner. The teacher patiently taught me that I want to be a hermit crab, and others think I am a crab. Finally, you can print your own works in 3D mode.
A happy activity really makes people reluctant to leave.
In a blink of an eye, 20xx years have arrived, and I have become a great scientist.
A few days ago, I developed an invisible potion. As long as I drink a little, I can't see or touch it for 24 hours. I was going to catch bad guys, so I drank a little, sweet, and soon disappeared. Then I went to places where bad guys often hang out. Soon, a thief who stole money appeared. He is walking towards the bank. I immediately ran over and tripped him to the ground, and immediately handcuffed his hands with cold handcuffs. The thief was brought to justice before he understood what had happened. Although this thing is easy to use, it will be unimaginable if it falls into the wrong hands. So I put it in the electric shock beam. As soon as I touch it, it will turn to ashes, and only the password can turn it off. So even mosquitoes can't get in!
I'm still inventing a panacea that can cure all diseases. It was almost successful, and suddenly my mother's cry came from my ear: "Don! Have you finished your homework? " It suddenly occurred to me that all this was my imagination! I hope this is true! So I must study hard to make this dream come true! Make due returns to the people and the world.
Teacher's comment: Your imagination is great! From your fictional story, the teacher realized: you are really a good boy with a clear love and hate and ready to help others! Your imagination is reasonable, the plot is vivid and complete, the sentences are fluent, the levels are clear, and the composition is progressing rapidly. The teacher is very happy. Work hard and try to write better!
Today, one thing makes me happy beyond description, because my mother and I are going to the science center that we have been waiting for for for a long time.
Along the way, we were in high spirits and always fantasized about the appearance of the science center. When we got off the bus, we were presented with a spectacular, majestic and very beautiful scene. It's totally different from what I expected. When we entered the science center, we saw rich and colorful scientific information.
We walked into the experimental discovery hall with excitement and expectation. When you enter the museum, the first thing you see is the high point of the Museum of Experiment and Discovery: the electromagnetic stage. A hostess said: "electromagnetism will make people feel creepy. Women with long hair can try it on stage." I saw that my mother's hair was very long, just like what the hostess said, so I asked my mother to try it on stage.
Miracle appeared, mother's hair really stood on end, so straight, as if she saw something terrible.
Then we came to the hall of perception and thinking, then came to the mirror maze, and entered the maze. Thousands of mirrors shine on us, which makes us see things in a blur and can't tell who is who. We walked left and right, but we couldn't get out of the maze. Once, we saw the exit, but more exits were reflected in the mirror.
Besides these, there are many interesting scientific phenomena. I will definitely go to the science center next time.
