My whimsy fourth grade composition

In our daily study, work and life, everyone will be more or less exposed to writing. Writing a composition can exercise our habit of being alone, calm our mind and think about our future direction. In order to make your writing easier and more convenient, here are the fantasy fourth-grade compositions I collected for you, hoping to help you.

My whimsy 1 In our life, we often have some whimsy and want to invent some magical things, such as "flying wooden houses". Especially in this virus era, it would be great if there could be a "flying wooden house".

And I will introduce my fantastic idea-"super mask".

The "super mask" looks similar to ordinary medical surgical masks, but its function is hundreds of thousands of times! Wearing it, no virus can invade our bodies, and it can be recycled for a long time, one year? Two years? Three years? You underestimate it, it can be used badly, and it is affordable, as long as 10 goes to 20 yuan. It can also be used as a gas mask in an emergency. The size can be adjusted, and adults and children don't need to worry about the size.

For example, for example, there is a sudden fire at home, and the smoke is heavy and choking. At this time, the "super mask" can act as a gas mask and even turn high smoke into fresh air. In this way, we can escape smoothly.

This is my whimsy-"super mask", isn't it cool?

My whimsy 4 th grade composition 2 I want to invent a convenient schoolbag. The schoolbag has many compartments and a pencil box, which is light to carry or you can walk by yourself.

Or the robot can help me with my bag.

Pack as many books as possible in the schoolbag. The shape of the schoolbag is very beautiful. There is a beautiful little girl in the pink schoolbag. If your back is tired, you can ask the robot to help you. The two straps are pink, and there are four compartments beside them, which can hold water bottles. There is also a big pencil box in it. You can put as many pens as you want. Straps are also easy to carry.

How nice it is to have such a schoolbag! You must cherish it after buying it.

My whimsy, grade four composition 3, music is playing! Open the curtain. Lights up! Ok, please take a look at my invention-the ever-changing boat!

This ship is very beautiful. It is a blue ocean and a golden beach with a green tree on the beach.

Although it is just an ordinary small wooden boat, it is amazing! You see, as soon as I stepped in, it jumped out of the steering wheel and the operating system board. Let's go to the bottom of the sea first, press the "diving mode" button, and the ship will immediately cover itself with a glass cover. Eject the spray pipe and fish tail from the bottom of the ship; Jumping out of bed, food and air are provided on board. To put it bluntly, this is a submarine

The seabed is so beautiful! But now I want to go back to land. The airbag popped up, causing the boat to surface and return to land. It retracts the jet pipe, air supplier, ejection wheel, claws, suction cups, propellers, wings and launchers. With claws and suckers, climbing a mountain is as easy as climbing stairs!

The ship quickly climbed the cliff and began to accelerate, running and running quickly. Last 3, 2, 1, lift off! The ship became an airplane. Start your flight!

Although this kind of ship has not been invented yet, I believe it will be born in the near future!

My whimsy: There are more and more people on the earth now, and I sometimes think: wouldn't it be great if we could build our homes in more places?

My imaginary space room is like this: it is a cylindrical room, made of tempered glass, and even the fast-moving space junk will not be damaged. It produces centrifugal force through its own 360-degree rotation, which makes people stand stably in the curved surface of the cylinder. Then, people can build an artificial sun and fix it in the center of the house. At night, you can turn on the power and let the artificial sun light up. After that, put some green vegetation and soil in it and water it regularly with the water pipes above, so that people can live happily in it.

I also imagined a house in the ocean. This is a house similar to a giant submarine. Every once in a while, it will float to the sea surface of Shanghai and inhale a lot of air. In this family, you don't have to worry about food shortage, because you can eat delicious seafood at any time. The steel box glass used to make a house is specially treated, and it will be fine even in the deepest sea.

I hope my whimsy can come true one day!

Now the traffic is very crowded, and I want to invent a green and anti-theft motorcycle-smart motorcycle.

The appearance of intelligent motorcycle is similar to that of ordinary motorcycle, except that there is a blue button and an alarm. It can press the blue button in traffic jam, stretch out a pair of "wings" and fly into the sky. When a thief comes to steal a car, he will get stuck whenever he touches a motorcycle, and the alarm will sound an alarm. Motorcycles are made of a special kind of metal, which is very strong. Behind the seat is a big box with a pair of wings, which will automatically extend when you press the button. There is an alarm above, which can alarm and absorb solar energy as the power of motorcycle; It can not only absorb solar energy, but also absorb the energy of the moon and store it. Motorcycles also have fingerprint locks, which can be automatically unlocked by the owner by pressing them. Its name is smart motorcycle.

If everyone has such a smart motorcycle, they will no longer be afraid of traffic jams or thieves stealing it, and it is green and energy-saving.

On a hot summer day, everyone always cries, "It's so hot! It's so hot! " However, don't worry now, because the portable refrigerator I developed will be on the market soon.

One day, my throat was very hot, and I suddenly remembered that there were popsicles in the refrigerator in my pocket, so I took out this portable refrigerator. There is a red button on the right side of this refrigerator. Just press this button, and it can zoom in or out freely. I click this button and say, "Get bigger". It will soon become as big as our usual refrigerator.

Suddenly, my brother saw this refrigerator, his eyes lit up and he said, "What is this?" He leaned in and said, "It turned out to be a refrigerator. What's inside? " At this time, if I tell him that there are popsicles in it, he will definitely haunt me. No, I can't tell him. So I said, "Nothing." "all right." My brother turned and left. I'll put it away and put it in my pocket at once.

It also has many functions, such as: you can put everything in it and travel around the world with it; You can zoom in and out of what you put in the refrigerator together. ...

If you like this refrigerator, please order it from me immediately!

As students in the new era, we live in a happy and comfortable environment. But time will keep changing and people will keep improving. Maybe in 20xx, there will be many robots in people's lives to accompany you since childhood, protect you, love you and even do anything dangerous for you.

20xx is the age of robots. Robots can be seen everywhere on the earth. These robots have the same appearance as people and are smart, but they have no flexible ideas. Of course, this is a kind of human wisdom, in order to prevent robots from overthrowing human rule.

These robots have a wide variety and a clear division of labor. The same robot does the same thing, but it looks different. Like people, every robot is unique.

Naturally, we humans are not idle, and we will also find the shortcomings of robots and then further improve them. Robot researchers will research and develop new robot varieties. At that time, everyone will have a lot of time to think and experiment, and people will be smarter than now.

I wish I had a bug that can eat advertisements in my fourth grade composition 8 "Fantasies in the World". It's shaped like a scorpion. The only difference is that its head is sharp and green, its body is pink, its feet are blue, its poisonous needle is purple, its tail is yellow and its pliers are red. If I see a small advertisement, I will put this bug on it. It only takes a minute, and the small advertisement disappears without any residue.

I hope there is a kind of garbage-eating bug that looks like a dragonfly. Its head is green, its body is blue, its feet are yellow and its wings are transparent. If I have garbage, just put bugs on it and it will disappear in a few seconds.

I wish there was a kind of wastepaper worm, which is shaped like a butterfly. I don't need to say the characteristics of butterflies. I will talk about its color. Its head is black, its body is blue, its tail is green and its wings are blue. If I have a piece of waste paper, I only need three times five divided by two to eat it up.

I wish I had a bug that eats waste glass bottles. It is shaped like an aphid. Its body is green, its head is black, its feet are blue and its wings are blue. If I have an abandoned glass bottle to deal with, I can put this bug in it and eat it in 5 minutes.

I hope too. ...

Today, I finally invented a multifunctional umbrella. Although it looks similar to other umbrellas, it has many magical functions.

It is colorful. If you don't like the pattern on it, press the red love on it and say what you like, and it will become your favorite pattern.

Let me talk about the structure of the umbrella. There are some buttons on it, like some lotus leaves floating in the river, with different shapes and golden lace on the edge. Very beautiful.

It has many functions. If you forget to bring an umbrella when it rains, just say the umbrella and it will fly to your hand and open automatically. If you want to travel abroad, but think the air ticket is too expensive, just press the white button and the umbrella will take you where you want to go. You can have fun by pressing the white triangle cold wind in summer. You are not afraid of cold in winter, and the umbrella will blow out warm air.

This is a wonderful umbrella.

What I want to invent is a time machine, which is about the size of a model plane and can carry 30 people for time travel.

Although this time machine is small, it has the function of zooming in and out. When you want to travel in the future, you will find that the plane is too small to get in because you didn't press a red button under the plane. After pressing the red button, there will be red light on you, and you will become as small as an ant, so that you can enter the time machine.

After entering the time machine, enter the address you want to arrive at first, and then press the yellow button on the plane. As long as you press the yellow button, the time plane will open just for sightseeing and fly in just for sightseeing. When the plane stops, press the red button next to the plane again, and the plane will glow red at you again, and you will become bigger soon. Time travel takes a long time, six hours. After six hours, time will automatically make you smaller, then suck you into the time machine and take you back to your home.

This is the time machine I want to invent. I must study hard and make progress every day. When I grow up, I will invent a real time machine.

My fantasy fourth grade composition 1 1 I believe that everyone had many dreams when he was a child, and I was no exception. One of my dreams is to invent a multifunctional pen with red, blue and green buttons on it. Each button has a different function. Let's have a look!

The first button is red, and its function is encyclopedia question and answer. If you press the red button and ask it any questions, it will answer any questions. If you don't understand anything in your study, just ask it, and it will be a good teacher for you.

The second button is blue and has my favorite function, that is, animal translation function. This button can understand what animals say, and translate your words to animals, which can deepen my feelings for animals.

The third button is green and has the function of drawing. It can carry out three-dimensional painting, also known as 3D printing. If you want to switch colors, you can, as well as automatic coloring mode and help painting mode.

Is it a magic pen that is particularly convenient? I will invent it one day.

There are many robots now. Do you know what my robot is like?

My robot has two buttons, one is red and the other is green. The red ones are land vehicles, and the green ones are

Vehicles in the sky. When you want to travel, you just press the red button and say, "I want to travel." It will immediately become a tourist bus to take you there, and will also prepare some tourist supplies for you. When you get up late for school, you just have to say to it, "I'm going to school." It will become a bicycle. You don't have to pedal. Sit on it and it will take you to school soon. It can also be turned into an airplane. You press the green button and a plane appears in front of you. Whether in a car or an airplane, it will emit air-conditioning in summer and hot air in winter. Speaking of which, I forgot to tell you that only its owner can control it, and it can distinguish its owner's fingerprints and voices from those of others.

This is the robot that can become various means of transportation and distinguish its owner from others.

My whimsy fourth grade composition 13 I have a whimsy, which is to invent a universal robot to make people's lives more convenient.

The shape of the robot is made of a humanoid robot. The round head is its control center, used to store all kinds of information. Eyes and ears are its sensors and information receiving antennas. There is a display screen on the chest, which can communicate with people. Behind it is a large solar panel, which is used to charge its heart-motor.

Robots store a lot of information and can also collect information through wireless networks, so they become good helpers for children. It can read poems to children and tell them the secrets of the universe, and it is an excellent tour guide to take them to see the beautiful scenery around the world. ...

Robots are also good helpers in people's lives. It can be connected with TV, air conditioner, refrigerator and other household appliances, which is convenient for people to manage housework. It can also carry out regular physical examination for people, such as temperature measurement, blood pressure measurement and fluoroscopy, and then give medical advice and formulate corresponding healthy recipes according to the situation.

Although the robot I introduced is still imaginary, as long as we study hard, everything in the fantasy can be realized.

My whimsy fourth grade composition 14 Everyone has his own whimsy. My whimsy is to transform the chair. You think it's as simple as changing chairs? Then you are all wet. I want to transform ordinary chairs into "multifunctional chairs".

Its appearance is almost exactly the same as that of an ordinary chair, except that there is a steering wheel with a board and a flat plate on it. Why is this kind of chair called "multifunctional chair"? Because this chair can change bread, milk, toys, rice ... in short, this chair can change many things.

This kind of chair is also more suitable for traveling. First of all, you can turn the chair into a flying train, put the chair in the last carriage, look at the grotesque "cotton candy" through the window, listen to the cries of eagles outside, smell the natural air outside, taste the bread made by the chair and touch the train. It's really reliable

When you arrive at the tourist destination, put the train away and turn it into a tent, and then take a photo. At night, look at the moon and stars in the sky for a walk, enter the tent and have a comfortable sleep.

Do you like my invention? I will be successful when I grow up!

My whimsy fourth grade composition 15 feet grow every year, and shoes have to be changed every year. What a waste of money! So I want to invent a pair of "smart shoes".

This smart shoe is made of nano-materials, which is very strong and light, and the key is waterproof. This smart shoe does not need to be recharged. As long as you walk a few steps, the smart shoes will be charged with one grid. If you want to fully charge the power grid, you only need to walk a few hundred steps.

Smart shoes will also automatically adjust the temperature with the weather. In winter, smart shoes will automatically keep warm; In summer, smart shoes will automatically cool down. If your little feet stink, smart shoes will automatically deodorize, sterilize and disinfect. Smart shoes will also collect data such as your weight and blood pressure, and judge your health status according to the data changes. Once the abnormality is found, it will automatically call 120 emergency number for you! If some decorations on your shoes fall off or are damaged, smart shoes will remind you to take good care of them and help you repair them.

If only nano-materials could be used to make the smart shoes I mentioned! However, with the changes in science now, I believe it will be in the future.
