I want to invent an excellent composition of 450 words.
I want to invent an excellent composition of 450 words 1 In the future, world science and technology will develop rapidly. The multifunctional robot I invented was one of the most advanced robots at that time.
In the past, when high-rise buildings were built, some reinforced concrete was often transported to a very high place. This requires workers to take the elevator to carry cement up. But this is very dangerous. If something goes wrong, the elevator will fall and kill people. But even if it is so dangerous, the workers still have to do it. With the increase of high-rise buildings, how many workers will fall to death every year! In order to solve this problem, I invented a multifunctional robot to solve this problem. This robot is 40 meters high. 3 meters, the arm is 30 meters long. It can move 70 tons of steel bars to a height of 50 meters. He is an expert in building tall buildings. Does it need electricity? Of course, it needs electricity, but it can convert sunlight into electricity with solar panels, so it doesn't need to be charged. Just use the remote control. Press the red button and it will start working. Press the yellow button, and it will transport the reinforced concrete to Gai Lou. If you press the red button again, it will start painting. With this kind of robot, it is much easier for engineers, just use the remote control to command.
This robot can also carry out high-rise fire fighting. As long as you press the green button, several streams of water will immediately gush out from its arm to put out the fire. Because it has a protective film on its surface, it will not be burned by fire. Its protective film can also convert sunlight into electricity, which is equivalent to a solar panel. But as long as you press the pink button, it will stop working immediately.
This kind of robot can build high-rise buildings and put out fires at high-rise buildings. Is it convenient?
I want to invent an excellent composition with 450 words and 2 words. As the temperature rises, the ice surface of the North and South poles will melt, and the sea level will rise by X meters, which may lead to a major flood. I have known this news by heart for a long time, but I can't help it. What should I do? So, I want to invent a time-space table that can control time.
The space-time table I want to invent is to fix the pressure in the table with high-tech precision instruments, so that it can produce negative energy substances and form 1 small wormhole pressure points. Can be completely free from time constraints. Similar to other ordinary watches, the light blue strap seems to be a charming light at night. There are two hands on the surface, one is a fixed hand, and the other is a year hand, which are protected by a cold light surface like Bai Yueguang.
As long as you put on the time-space table and come to the north and south poles, it is time for the time-space table to show its great power! At this time, as long as the static needle and the annual needle coincide, the time and space of the north and south poles will be completely static, and the hypothesis of the flood will naturally be vulnerable!
There are many water-deficient countries on the earth, and China is one of the water-deficient countries in the world. In order to alleviate the water shortage crisis, the time and space table can also help. As long as you take out the magical time-space table and let it come to the north and south poles again, the problem can be solved. Don't underestimate this small space-time table, which is full of ingenious ideas. The needle in those days was not a fuel-efficient lamp. All you have to do is poke the needle of the year at the north and south poles, and you will find that time passes very quickly. After a while, the ice turned into water for us to use. Once there is enough water, you can immediately pull the static and dynamic needle to stop the time and space instrument from working. Do you think this is killing two birds with one stone?
How come? Don't believe it? Wait and see!
I want to invent an excellent composition with 450 words and 3 words. Everyone wants to invent something novel, and of course I am no exception. What I want to invent is high-tech glasses.
With the changes of the times and the progress of science and technology, high-tech glasses are gradually popularized and used by people. Its shape is similar to that of ordinary glasses. It has two lenses and is transparent. But this lens is very different from the ordinary lens. It is made of nanotechnology. Although it is light, its strength is 100 times that of steel. No matter how you fall, it won't break like ordinary glasses. It can not only make phone calls, download all kinds of software and watch videos like a mobile phone, but also automatically turn on the blue light and radiation protection functions to protect eyes. If you are stared at by the bad guys outside, don't worry, you just need to call 1 10 in your mind, because a very small mind sensor is installed in the lens, which can sense everything in the human mind and keep you in a safe state at any time, so that the bad guys are afraid to approach. With high-tech glasses, not only life is convenient, but also the safety factor is improved, which can be described as killing two birds with one stone.
You must think that this kind of glasses can only be worn by nearsighted people, which is all wet. This magical lens can automatically sense whether you are nearsighted or not, and automatically switch between nearsighted and non-nearsighted pages according to the situation. In this way, when you wear glasses, your eyesight will be in an excellent state, greatly reducing eye fatigue. In addition, the glasses also have medical functions, which can automatically detect whether the wearer has diseases and tell you how to prevent them in advance. Is this function very powerful?
How's it going? My invention is good! If this kind of high-tech glasses is really invented in the future, it will play an infinite role among the people and the sales volume will definitely be good.
I want to invent an excellent composition. 450 words and 4 strokes are our good friends and play an important role in our life. Nowadays, people are very smart, and the pens invented are beautiful, but they all have some fly in the ointment. For example, the pen I use is made of thin plastic, with a cap and a pen holder, and it breaks when it falls to the ground; The pen tip is made of iron, and it will bend when pressed hard, so it is easy to wear, so I want to invent a magic pen.
Why is it called a magic pen? Because it is made of stainless steel, it will not break no matter how it falls, and it is equipped with a special nib and ink bag, so no matter what the nib writes on, there will be no problem. The most amazing thing is that the ink sac in the pen will never be used up.
If you think this is the magic of the magic pen, you are all wet! There are three buttons on one side of the magic pen: red, yellow and purple. When you encounter an unsolvable problem, just press the red button and a mind map will appear immediately to help you sort out what you learned today. When you come across a word that you can't write, you can press the yellow button, and a trick to remember the word will appear immediately, which is very convenient. When you write a wrong word, you just need to press the purple button, and the wrong word just now disappears. But don't think that with this pen, you can be lazy in the exam, which is completely unworkable, because it will become the same as an ordinary pen no matter how you press it in the exam.
In order to invent this pen, I must study hard and create my magic pen with my knowledge and strength.
I want to invent an excellent composition. Inventing a car is my ideal and dream. What kind of car do I want to invent? Let's have a look!
The car I want to invent must be fashionable first, otherwise I don't want it! First of all, the roof must have a skylight, so that it will be cool in summer. The second car must have an air conditioner mp3. Air conditioning can help people reduce the heat. Music is the most relaxing thing for people, and its feeling can make people feel comfortable. Third, the color of the car can change with the seasons. The reason why it is warm in winter and cool in summer is that the car will change color and the car shell will feel dazzling when driving on the road. I will name the car "Chameleon Car".
Other people's cars bring convenience and speed, but mine is different from others'. It brings warmth and comfort to people. My car is like a home, like a house with at least hundreds of thousands, plus furniture and utilities, millions are gone, and my car only needs between 1 10,000 and130,000, which is much cheaper than buying a house or something. From this, I thought of a story I invented in the car: once, I slept in my room and my father slept in my car. My neck twisted in the morning, but my father was "intact". He said, "Baby, the car you invented is so comfortable that I still sleep here tonight." ..... I am still immersed in this "dream", as if I were there, as if I came to this dream myself.
"Thousands of teachers in Qian Qian teach people to seek truth, and thousands of students in Qian Qian learn to be human." This is Tao Xingzhi's famous saying. Now that I have decided this goal, I will move towards it! Come on!
I want to invent an excellent composition. Every time I see someone being stolen on TV news because the anti-theft measures are not in place, I feel worried at once for fear that thieves will come to our house. At this time I will think, I want to be an inventor when I grow up. Invent an electrified wall so that thieves can't steal it.
This electrified wall was originally a chip the size of a Rubik's cube, which was very light. You put this chip on the ground, press the blue button on the box above, and it will immediately become a high wall with a scanner on it. This scanner has the functions of facial recognition and fingerprint recognition. If we use facial recognition, then we just need to adjust the scanner and keep it still until the scanner finishes scanning. If you use fingerprint recognition, you only need to put your finger on the scanner until the word "input complete" comes from your ear and the setting is successful.
Next, I'm going to talk about how the electrified wall is anti-theft. If we go out, just press the blue button above. When we get home, we will find that the door is blocked by an electrified wall, so that thieves can't enter through the door. Maybe you will ask, what should thieves do if they want to destroy the city wall? If this is the case, then when the thief destroys the wall, the wall will generate electricity, making the thief get an electric shock and unable to walk. At the same time, the charged wall will automatically send out a positioning alarm to let the police take the thief away. If we come back, the charged wall will recognize our faces and automatically become a small chip. In this way, you don't have to bring your keys when you go out in the future, and you are not afraid of forgetting to bring your keys and losing them, so you can't get in.
I believe there will be such electrified walls in the future. As long as we study hard now, there will be more high-tech in the future.
I want to invent an excellent composition. Science is more and more developed, and the door is more and more advanced. However, there are still many shortcomings in the current security door, so I want to design a unique security door to benefit the people.
The shape of the security door I designed is the same as that of the robot. The robot's eyes are the "cat's eyes" we used to look at people at the front door, and the robot's hands are the handles of the front door. He uses a fingerprint smart board. The robot's mouth is used to talk to the outside world, and there is a microcomputer in it to control the smart board. People who are tired from work will be very happy when they get home and stand in front of their homes. The first thing they saw was the cute appearance of the robot.
The interior of the security door I designed is controlled by high-tech passwords. The head of the machine, like the mainframe of the computer, controls the whole robot body. The fingerprint input by the smart board and the memory of the microcomputer are controlled by his head. When the master comes back, first of all, the robot's eyes will bend and its mouth will smile and say "hello!" " Three times. When the owner presses the smart board with his thumb, the microcomputer will make a judgment immediately. Open the door in one second. If a thief comes, presses his fingerprint, and the microcomputer finds that something is wrong, the door will open hard, bump the thief into the corner, and then recover within one second.
I designed the security door and information system. When the host is not at home and a guest visits, if the guest wants to leave a message, he can dial the phone number of the host on the robot foot, and a smart board will appear inside, so that the guest can write what he wants to say and restore to the original state. When the master comes back, as long as he presses his fingerprint, the robot's mouth will tell the master the content of the message. If the guest and the host want to buy something and leave, and the guest has something urgent to go out, the guest can come out by pressing the nose of the robot.
Hey! This kind of door I designed is ok! In the near future, Dr. Dai Han will succeed.
I want to invent an excellent composition, 450 words and 8 words. Scientists observe the shape of whales-they find that streamline makes the boat go faster. Are there many mysteries inside the fish? So, I want to see our little goldfish.
I have a question when I observe the little goldfish. I can't control the ups and downs when I swim, but the fish can swim up and down easily. Is this related to the internal structure of fish?
I looked it up on the internet and understood the mystery. It turns out that there is a bubble called swim bladder on the small fish. When a small fish wants to sink, the air in the swim bladder will be released. On the contrary, if a small fish wants to float, it will be full of air. So, I thought I would invent a swim suit that is very sensitive to water.
Although this dress is double-layered, it is very thin, because the middle of the two layers is empty. So it can be used as a raincoat. There are two thin tubes outside it, which are used to inflate. It looks no different from ordinary tubes. But when it comes to rain, it will absorb the air between the two layers, so that only the outer layer will be wet and the inner layer will not be wet.
It also has the advantage that it can be used as a life jacket and provide oxygen. Don't panic if you accidentally fall into the river. Because if those two pipes suck a lot of water, they will face down because they are too heavy, and at the same time, they will draw oxygen from the water and make people float. And if you sink into the water at once, be sure to wear a hat, so there is no water in it, and the pipe will provide you with oxygen.
I thought, "Nature is really a good teacher for human beings. A small swim bladder can also become such a magical swim bladder dress! " "I believe that in the near future, my invention will be successful, benefit mankind, reduce the number of deaths in the water and make the world a better place!
I want to invent an excellent composition. I watched the endless stream of cars on expressway, trying to invent a car of my own.
The car I want to invent is not as monotonous as the current car, and it has protective functions all around. This car has two characteristics: first, the car can be parked anywhere, it will absorb the light energy of the sun, recharge, and the shell is colorful; Second, there are four buttons in it. They are red, yellow, blue and green. Someone asked, "What are these buttons for? What's the use? " I tell you: "They are very useful!"
When the weather is hot, as long as you press the red button, fresh air and cold air convection will be emitted from the car. There are also cold drinks in the juice box, which makes people relaxed and happy. When the weather is cold, as long as you press the King Wong, the heating will come at you and pervade the whole car, making you feel the warmth like spring.
If you want a car to run on the water like a boat, just press the blue button and the wheels will contract immediately. A rotating fan blade will automatically extend from the rear of the car and move freely on the water! When you go ashore, press the blue button again and it will immediately return to the appearance of the car. If you want it to fly in the sky like an airplane, you just need to press the green button, and two big wings will stretch out on both sides of the car, and a jet plane will emerge from the rear of the car and become an airplane, so that you can fly freely and enjoy flying in the air. Press the green button after playing enough, and it will slowly land on the ground and change back to the appearance of a car.
This is the car I want to create and invent. I hope my invention will succeed! Let the dream come true, so that everyone can drive the car I invented!
I want to invent an excellent composition of 450 words. When I was a child, I had a dream-to be a scientist when I grow up. If I really become a scientist, first of all, I want to invent a suspended car.
The shape of this car is like this: the front is big and the back is small, which is a streamlined model. Doors on both sides are made of anti-collision steel, and the front windshield is made of bulletproof glass. There is an air propeller at the rear of the car to make the car move forward; On the roof, an air sensing plate is installed. As long as the air is sensed, it will provide power for the car.
When you get into the car, you will find that there is no keyhole! Hehe, look at the right side of the steering wheel. There is a fingerprint detector. You put a fingerprint on it. If your fingerprint matches the owner, the car will start. Otherwise, you will call the police directly. Above the detector, there is a GPS navigator. However, this navigator is different from other navigators. It can not only guide the way, but also report the shortest shortcut for the owner after entering the destination, and can also book rooms, air tickets and tickets. Why does a car lack air conditioning? My suspension car also has air conditioning, but it can adjust the internal temperature according to the external temperature. For example, when it is 38 degrees outside, the air conditioner in the car will be adjusted to 24 degrees to cool you down for a while. In addition, a holographic projector, radio, computer and refrigerator are installed in the car.
So what makes it float? The answer is under the car. The bottom of the car is equipped with a suspension machine, which can make the car suspend at a height of about 60 cm. Suspended cars can travel on land or on water.
Although it is only a "if" now, I believe I can invent this kind of car in the future.
I want to invent an excellent composition of 450 words: 1 1 When people go out to work or travel, they have to carry a big bag and a small bag, which is very heavy and tired. I saw people working hard, so I had an idea. If there is a retractable backpack, it is both convenient to carry and beautiful.
Small backpack is rectangular, with food on both sides. You can have as much as you want. Daily necessities are put in the big grid. Behind small backpack are two straps and two cushions. When you carry it on your back, the strap will help you massage, and two balls will appear on the mat, rolling around on your back, which is very comfortable.
There are three buttons in front of small backpack, which are red, yellow and blue. The red button is equipped with anti-theft equipment. If a thief comes, small backpack will become a robot to protect its owner, give an alarm and send a message to the police so that they can catch the thief. The blue button is the weather forecast. If it rains, small backpack will make a sound, and it can also forecast the level of typhoon or rainstorm and the weather in the next few days. The yellow button is the device to find the owner. If the owner forgets to take small backpack somewhere, a spiral leaf will fly from small backpack's head, and two detectors will grow on both sides of small backpack to detect where the owner is, and then contact the owner.
Small backpack has two other functions. If you put important things in it, small backpack will be as strong as a safe. Although small backpack is made of cloth, this kind of safe is indestructible. You must enter the password to open it. It can also identify the owner.
With this small backpack, our life is more convenient.
I want to invent an excellent composition of 450 words 12. Many people in the world want to invent something. What I want to invent most is an oversized coat that can be invisible, change color and fly.
This coat is like a chameleon. It will change into different colors according to different functions. It has a hat, which is bigger than a schoolbag. The coat is furry inside and there are several pockets inside. That pocket is very big and can hold a lot of things!
This coat of mine has many functions.
Function 1: If I am alone at home and thieves come to my house to steal things, I will not be afraid. All I have to do is whisper, "gown, there are bad people coming to our house!" " "The big coat will come to me invisibly and climb on me. In this way, I became invisible. I'll take off my hat again and become cross-eyed. At this time, the thief should open the door and I will jump out. At this time, the thief will see a cross-eyed flying around, scaring the thief to death, running out at once and never stealing again!
Function 2: If one day I need to wear a coat when I go out, but I don't know what color to wear, I will send an instruction to my big coat: "Big coat, you see I'm going to attend a very important activity today, but I don't know what color coat to wear, please help me!" It looked like a pair of eyes at this time, and I immediately put on a coat of the right color, which made me feel very happy.
Function 3: If I want to go to a place with my family, but I don't want to ride for a long time, I can put on my big coat and say to it, "Big coat, I want to go somewhere", so the big coat will take me directly.
This is what I want to invent, a powerful coat, I like it very much, and I really hope to wear it one day.
