My whimsical composition in the fourth grade

In normal study, work or life, everyone will inevitably touch or use composition, which can bring our scattered thoughts together. In order to make your writing easier and more convenient, the following is my fantastic composition in the fourth grade, which I carefully arranged for reference only. Welcome to reading.

In the fourth grade, my whimsical composition 1 smacked, no! Why is my tongue broken again? If only I had a multifunctional pen.

I designed a very easy-to-use multifunctional pen, using a plastic cover and a small compression device. I also used a nano-nib. There is a sound generator at the top, and there is an audio data conversion chip in it to transmit sound. There are three buttons on it with serial numbers. It's all white outside, almost like an ordinary pen.

This multifunctional pen is very portable. Please press the 1 button immediately. At this time, it will shrink into a small stick like a capsule. You can put it in your bag and trouser pocket ...

This pen can also play music. You need to plug the earphone connector into the connecting hole on the right, and then press the voice button to say what song you want to listen to. This multifunctional pen can analyze a difficult problem and check homework, which is a very good function. The second button is to check the homework, and the third button is to analyze the topic. If you put the pen as high as possible in front of the homework paper, it will project your mistakes and circle them. When explaining the topic, he will scan it, then say the answer word for word, plus the idea of solving the problem. Even if he encounters similar problems in the future, he will not be wrong.

I will study hard and I will invent this pen when I grow up.

I want to invent an intelligent multi-purpose schoolbag when I grow up. It has many functions and is also very practical. The most important thing is that it is smart.

Its material is a special nano-component, which can meet our ever-changing shape. It can be any shape you want. Its colors are also colorful. We can change the color according to our own preferences and weather conditions. There is also a smart recording button next to the zipper. Click and say what you want to do, and it will be done right away.

Let me introduce the functions of its various shapes. This kind of schoolbag is all right. Just say the password becomes smaller, and it will become very small, like a piece of candy in your pocket. Don't worry about the weight of your schoolbag. It will be more convenient if you press the abnormal button. It can grow four wheels, become the shape of a car, and send you to school. When you get to school, just use the password and put it in your pocket. Isn't it great?

It also has the function of a nanny. As soon as the bell rings, you don't need to bring textbooks, stationery and other school supplies. As long as you point its camera at the teacher, it will automatically scan the teacher in class and then spit out the textbooks and stationery you need. In addition, it can help teachers and parents to correct their homework. As long as you put the written homework into its stomach, it will be corrected intelligently and with a red pen. When we encounter a problem, it will become a robot to explain it to you. She is really our good nanny!

By the way, it can also be transformed into electrical appliances we need on weekdays. For example: tablet computer, TV, mobile phone.

How's it going? Is the schoolbag I invented omnipotent? Do you want to have such a schoolbag now? Then let's study hard and work hard for it

My whimsical composition is Grade 4, Grade 3. Everyone will have a multifunctional notebook in the future. Let me explain its function.

It can be carried around, because it can be as small as a nanometer when you are not using it. All you have to do is say the smallest and put it in your pocket.

Between you and me, I will be a scientist in the future. In order to prevent people from wasting money on books, I invented multifunctional machine books, each of which only costs 10 yuan, with many functions.

If you accidentally lose it, all you have to do is say "take back the multifunctional notebook." It only needs less than 0. 00 1 sec will come to you, no matter how far it is, it will come back at the same speed.

Ordinary books get wet when they meet water and turn to ashes when they meet fire, but my multifunctional machine book is invincible, hundreds of millions of times stronger than that steel bar. Am I great? Needless to say, it can't even destroy an atomic bomb.

Now I really want to read Sherlock Holmes, so I said, "multifunctional machine book, I want to read Sherlock Holmes." As soon as the voice fell, it became Sherlock Holmes. God, I read it with relish.

Another function of the multifunctional computer book is that if you read for more than 40 minutes, it will automatically close to give your eyes a rest, and there are many irregular reading books, which will remind you that there will definitely be fewer people with myopia.

I only introduced the function of 1%. If you want to buy it, you only need 10 yuan to study for life. What are you thinking about? Come and order.

My whimsical composition is Grade 4. My invention is "flying shoes".

What are flying shoes? As the name implies, it is flying shoes. But this thing called flying shoes can not only fly, but also have other functions! Please listen to me carefully. Come on!

Flying shoes look strange, although they are similar to ordinary shoes, but if you look closely, you will find that there are two points on their uppers, one is black, the other is white, white stands for "on" and black stands for "off". If you press a black spot, it is an ordinary pair of shoes. Once the white dot is pressed, it will look different, and the quick device and hot wheels will pop up on its sole. Hot wheels is very hidden. Only by careful observation can you see that it is hidden in the sole, revealing some red spots. Since they are flying shoes, they naturally have wings. Wings will stretch out on both sides of the shoes, shoelaces on the wings will "grow", laser cannons will arch out at the same time, and fire-breathing devices will stretch out on both sides of the shoes. When the wearer encounters danger or lack of oxygen, the sole will form a transparent object, called bulletproof oxygen protective cover, which can resist danger and transport oxygen, and is a necessity for the wearer in case of danger.

In addition to the strange shape, flying shoes are also full of praise! This flying shoe has many functions, but flying is the key. Flying shoes can go anywhere they want, make friends with aliens in space, turn on the oxygen furnace for deep-sea exploration ... If the balance is not good, it will screw up in the air! Don't worry, those two seemingly useless little wings critical moments will come in handy. They are balancers. Flying shoes, not only have these functions, but also can fire, accelerate running, form bulletproof oxygen protective cover and other strange functions.

This is my invention, and I believe that everyone can use it in the near future.

My whimsy composition 5 A in grade four whimsy is the star, and my whimsy imagines the sky. Now I'll pick any one. Please come with me and have a look at my imaginary desk.

My desk is made of transparent glass and looks no different from an ordinary desk. In fact, it contains "infinite power".

One function of this table is that if you sit incorrectly, the automatic display screen will display seven big characters "Your posture is incorrect!" " "This will enable students to correct quickly and prevent hunchback as soon as possible!

In addition, if you don't listen carefully or are distracted in class, it will give you a warning to study hard and listen with peace of mind. If you secretly eat in class and the nose of the desk smells, it will remind you "stop eating, there is plenty of time after class." In music class, if you write the word "music" on the desk, there will be many buttons. This is the equipment used in music class. If the teacher is going to teach the piano today, as long as you press "Piano", this magical desk will become a piano, and you can play it any way you want. In computer class, as soon as you write "computer", this desk becomes a high-end laptop again.

Some people will ask, the table is made of glass. What if it's crushed? This is your worry. To tell the truth, the glass of the table is all made of high-tech materials, which is unbreakable and can bear at least 20 tons of weight. Even if the whole class is crowded on a glass table, it is safe and sound. This kind of table can be used for at least one hundred years. If it can be widely used, it can save a lot of wood resources and protect forests. How's it going? This is a good invention.

My whimsy composition Grade 4 6 My whimsy is to invent a set of military equipment. No, listen to me first.

Anti-radar helmet can interfere with radar detection and not expose the position of soldiers. Moreover, it can also detect the position of the enemy within 10 km, present it in front of your eyes and kill them.

Why is it called a steel suit that expands with heat and contracts with cold? It is because in winter or underwater combat, it will be tightly wrapped around the soldiers, so that they will not feel cold. In hot places, it will become loose and there will be a cool supply. In addition, the clothes are equipped with steel armor, which is very hard, equivalent to wearing a 10 super bulletproof vest to protect the vital parts of soldiers.

Voltage shoes, when soldiers are tired, will release appropriate voltage, so that soldiers can wake up, run faster and take the initiative in the battle.

The GPS combat instrument, though only a watch, can tell you your exact position no matter where you are, even where there is no map, and tell you the best battle plan within 5 seconds. How's it going? Isn't it amazing?

The last one is a multifunctional automatic rifle, which can fire grenades, shotguns, sniper bullets and high-explosive bombs. You just need to adjust the shooting mode and install the corresponding bullets.

I believe that in the near future, I will turn my whimsy into reality and make our military strength stronger.

In our life, "basic necessities of life" have many shortcomings. Next, I will tell you about the "line" in life. Everyone should know that although there are cars now, traffic jams, car accidents and other inevitable things often happen. In the near future, I want to invent a safe flying car. What does it look like? Then continue to look down.

Flying cars are almost as big as ordinary riding cars! Its front end is a magical console with several buttons on it. Flying cars have big wings on both sides and two accelerators at the tail. Don't underestimate it. It can greatly improve the speed of flying cars. If you reach your destination, you may think it must be a landing. Then you are wrong. Flying cars will give each passenger a parachute and land slowly like dandelions.

If you have something to do, just make a phone call and several robots will automatically appear on the plane. They are city beauticians, waiters and bodyguards ... in short, they sweep, do and stay.

There is no need to press the button if the flying car is attacked by an unknown missile. There are automatic sensors on the flying car. Therefore, flying cars will automatically install double protective covers for passengers to ensure their safety.

If there are children on the plane, in order to prevent the children from being too bored, the driver can press the yellow button, and a playground will be pulled down on the plane to let the children play freely, so it is a pistachio.

Although this is not true, I still hope it will come true one day.

Our earth is getting hotter and hotter, because too much carbon dioxide constitutes a greenhouse gas, which constantly absorbs heat, leading to the temperature rise of our earth. I heard that planting trees can reduce carbon dioxide, so I want to invent a tree planting robot.

This tree planting robot has a culture room, a fast food box, a rainwater collector, four trash cans, a sprinkler and a box that can transform, burn and biogas garbage.

It can plant trees. It will collect the seeds of various trees and plant them in the cultivation room. The inner wall of the culture room is made of glass, so the seeds are not short of sunlight, and the water in the soil evaporates into steam, which is combined into water drops and drips back into the soil, so the seeds are not short of water. After the seeds germinate, the tree planting robot will plant the germinated seeds back to nature, and the sprinkler will pour the water from the rainwater collector into the soil to fertilize the soil.

It can handle and collect garbage. He will throw the garbage into his dustbin, and then the garbage will be sent to a box for treatment. For example, recyclable waste will be turned into treasure, and harmful waste will be burned harmlessly. Biogas kitchen waste will turn it into biogas or fertilizer.

It can provide some food for people. For example, when it meets an old man, it will give him some food to supplement his body; If you meet middle-aged people, giving them something to eat will make people feel refreshed; If you meet children, it will give them some snacks. Food is not provided until all the food has been provided.

I believe I will invent this tree planting robot in the near future.

With the development of human beings, the number of human beings is increasing, and the land space can no longer meet the population's living. In order to satisfy the population, there will be a second home in the world-underwater city. This area, which occupies 70% of the earth's area, will be fully developed and utilized.

In order to resist the great pressure of the sea, this beautiful underwater city is built in a huge coral, and you can reach the underwater city through a long corridor. As soon as you walk in, you can see the huge round water polo built in. They look light and fragile. In fact, they are very hard. Even if the hardest thing in the world hits them, they won't break because they are made of diamonds. This is the room where people live. Many people moved here from land.

Here, you will find that the temperature at the bottom of the sea is very similar to the climate on land in spring and autumn, and the temperature is also very suitable, so people live happily. Maybe you will ask, how can you live without sunshine and fresh water at the bottom of the sea? Don't worry, there are two huge machines in the deepest part of the underwater world, one is the sunlight processor and the other is the seawater desalination processor. The sunlight processor is connected with the ground, where it absorbs sunlight, filters out harmful ultraviolet rays and sends them to each water polo for people's daily use.

The seabed is an environmentally friendly world. Here, in order to protect the world, people have eliminated cars, trucks and other vehicles that are harmful to the environment and replaced them with well-trained dolphins. Because dolphins are considerate and docile, it is better to use them as a means of transportation.

Students, do you like the second hometown-underwater city?

My whimsical composition in the fourth grade 10 Since the 20th century, our country has developed slowly and invented many things. There are more and more cyclists on the road, and bicycles are rarely seen on the road.

Why? I thought about it. It should be that the bicycle is not only hard to pedal, but also slow. The car only needs to gently step on the accelerator and drive a distance. But cars have exhaust gas, which will pollute the environment. I want to transform bicycles to make them more useful than cars, so that people can use bicycles instead of cars and our air will be much fresher.

First of all, its shape is similar to that of an ordinary bicycle, except that it has three "red, yellow, green" buttons and a vacuum cleaner is installed under the wheel. What are the three buttons for? If you ride for a long time and are hungry and thirsty, just press the red button and tell it what you want to eat. In less than a minute, it will appear in front of your eyes. Isn't it amazing? What should I do if I suddenly get lost while riding? At this time, you don't have to worry, let alone worry. Just press the yellow button and tell it your destination. It will become a pair of wings and take you where you want to go. If you want to travel on water, you just need to press the green button, and it won't sink into the water. It will sail in the water like a boat.

In addition to the above functions, there is a hidden function, that is, no matter how you ride, you will not fall. How "welfare" this function is for beginners!

This is the bike I want to transform. Do you think the bike I want to transform will become a reality in the future?

In the fourth grade, my whimsical composition 1 1 can be seen everywhere in our lives, making our clothes look good and our lives convenient. But once the pockets can't hold it, or there are too many pockets to hold it, it's not convenient. So I hope to invent an infinite bag made of nanotechnology, which even an elephant can easily put in and ensure that the items are intact.

When you want to put an item into an infinite pocket, you just need to untie the red rope on the pocket and say "Take it" to the rope, and the infinite pocket will automatically open its mouth and eat the item. When you want it to release something, you untie the green rope and let it go to an empty place, then you can take out what you want.

Infinite pocket has a feature, which is anti-theft. Don't worry about being stolen at all. Even if the signal is bad, it can send a message to your watch. Not only that, when someone touches it, it will automatically turn on fingerprint recognition or pupil scanning mode. If it does not match the owner's information, it will immediately give out a continuous alarm. As long as that person doesn't let go, he won't stop. In this way, the thief can't do anything about this bag. No matter how he tore, pulled and stepped on it, what was in his pocket and what was in his infinite pocket would not hurt a hair.

Infinite pockets can also be used to move new year's goods during the Spring Festival. During the Spring Festival, we often bring a lot of things back to our hometown, or after the Spring Festival in our hometown, we have to bring many specialties from our hometown back to the city. At this time, the infinite pocket comes in handy, making people's long-distance travel much easier.

I believe many people hope that life will become more and more convenient. I want to invent an infinite pocket, which can reduce the burden on everyone and go into battle lightly. Are there any good inventions? Let's write it too!

My whimsical composition in the fourth grade 12 Every day when I go to school, I almost always encounter traffic jams on the road, and I did meet them again today. I sat in my father's car and looked at the long queue of cars, thinking, if only my father's car had wings!

I guess the future car should be what I imagined. The car uses a streamlined body to reduce resistance and looks like a colorful fish from a distance. Its color can also change with your mood! When you are angry, it will turn red. If you are shy, it will turn pink ... The car shell is made of carbon nanotubes, also called bucky tube. Carbon nanotubes are harder than steel. The window is made of transparent carbon nanotubes, and no sharp knife can pierce it. The tires of this car are made of ultra-light and ultra-soft rubber. When it meets something sharp, it will pop up an airtight balloon to protect the wheel.

It is not only sturdy and safe, but also multifunctional. It can drive on the ground, swim in the water and fly in the sky. If there is a traffic jam on the ground, it can stretch out its invisible wings and fly to the sky. Its speed is comparable to that of an airplane, allowing you to experience the thrill of flying without worrying about being late. It can use solar energy, and no solar energy can use wind energy.

This car is energy-saving and environmentally friendly. I hope this kind of car can be invented and manufactured by people. In that case, we can definitely have fresher air and bluer sky!

In the fourth grade, my whimsical composition 13 big data, cloud computing, internet of things. With the development of science and technology, great changes have taken place in our life from food, clothing, housing and transportation. The development of science and technology has also stimulated my imagination, which often makes me have many fantastic ideas. My whimsy is to invent an intelligent rainfall system.

In recent years, there has been drought and little rain in the north. Drought has many hazards, such as turbid air, dry land, withered plants and even difficulty in drinking water. All these problems can be solved if there is an intelligent rainfall system.

This intelligent rainfall system is like a circular UFO, with a diameter of 100 km, a spray hole at the top, a wind tunnel at the side, four wings and four wheels at the bottom. When floating in the sky, wheels and wings will be put away. Its material is an active high-temperature resistant resin, which is transparent when floating in the air. This rainfall system has many functions, such as weather forecast system, rainfall distribution system and smog cleaning system. It can accurately forecast the weather, measure the air humidity and air quality, and collect all kinds of data related to the weather, so as to judge where the drought is and how much rainfall is needed. Its most powerful function is the rainfall distribution system.

In southern China, there are often heavy rains and sometimes floods in summer. The north is sunny and prone to drought. At this time, the intelligent rainfall system will fly to the south, spray the ecological quick-freezing liquid with the spray hole at the top, turn the rain clouds into solids, and then blow the rain clouds over the arid north with the wind tunnel. At this time, the spray hole will spray thawing liquid again, and it will rain in the north. Don't worry about the flood, the intelligent rainfall system will decide how much rain it will rain according to the drought. In this way, there is no flood in the south, no drought in the north and good weather everywhere.

How about this intelligent rainfall system? Isn't it amazing?

My whimsy fourth grade composition 14 My mind is full of many strange things, which I call "whimsy".

I think, I am a postman, and I send letters to everyone every day to let grandma or others know whether their children's life is good or not. People who miss their children very much receive these letters, which can alleviate their missing degree.

I think the trees are full of sweet and delicious fruits and the ground is full of green vegetables, so that we won't go hungry and farmers can have a rest.

I think everyone has an inexhaustible wallet, so that those poor people don't have to beg along the street in the cold wind, and some people who have no money to treat diseases will treat them in time because they have money, so that there will be more laughter and laughter in the world.

I think every girl has a magic wand, so we little girls can change into beautiful and charming clothes and fluffy skirts anytime and anywhere.

I think if I have a multi-purpose car, my father can go to work more easily.

I think I am a little musician. When I am bored at home, I will teach dogs to bark and chickens to sing with me. Every sunny summer night, we all sing beautiful music to make everyone relaxed and happy.

This is my whimsy.

My Fantasy Composition Grade Four15 In the 22nd century, human society entered the high-tech era, and scientists invented a wonderful kind of clothes, which brought us a lot of convenience.

I came together in the morning and found it was already 7: 30. What are we going to do? What are we going to do? I'm going to be late for school, and I feel like playing a hundred drums. At this moment, I suddenly heard the reminder of clothes: "Master, you won't be late with me!" " "I quickly put on my clothes. It took me to the blue sky and quickly went to school. Hardly had I stepped into the classroom when the bell rang and the stone in my heart finally fell to the ground. I patted my clothes to express my gratitude to it and thanked it for helping me solve the problem of being late.

Physical education class lost his clothes in the third quarter of the morning. I look around, but I still have no idea. At this moment, I shouted: "clothes, clothes, come back quickly!" " "Suddenly, the clothes appeared in front of me. I quickly put on my clothes, and I was secretly glad: fortunately, this dress has the function of automatically finding the owner and solving the problem of losing things.

This dress has countless functions, so you can change the style according to your own needs. For example, going to the seaside for a holiday becomes an island suit; If you climb a mountain, it will become a sportswear; When you go to a party, it will become a dress ... this dress will change its style according to the owner's needs. As long as you decide in your mind, it will feel and change. Of course, people also need to go to clothing stores regularly to change the chips of clothes to ensure that there are more and more styles in the chips.

This wonderful dress not only brings a lot of convenience to our life, but also saves materials and is very environmentally friendly.
