My whimsy is 400 words for the fourth grade composition.

Everyone's childhood is full of fantastic ideas, dreaming of inventing some magical things when they grow up. The following is my 400-word fantasy fourth-grade composition. Welcome to read the reference!

My whimsy 400 words 1 I have designed several future shoes, including music shoes, sightseeing shoes, night walking shoes and temperature regulating shoes.

Music shoes-People put on these shoes, as long as they step on them gently, they will make beautiful music and make walking a pleasure.

Sightseeing shoes-these shoes have a small controller inside. Wear it when traveling, press the slow button in a scenic place, and you can enjoy the tour; Press the shortcut key, and in a blink of an eye, you will "fly" to another scenic spot, which is really time-saving, labor-saving and worry-free.

Night shoes-this kind of shoes has a small light bulb in front. Wear it at night, so you don't have to walk at night with one foot deep and one foot shallow.

Thermostat shoes-These shoes have thermostats inside, just like air conditioners. When the temperature is adjusted to 20 degrees in summer, it will be cooler than sandals; Adjusting the temperature to 30 degrees in winter will be warmer than cotton shoes. In spring and autumn, the temperature is adjusted to 25 degrees, neither too hot nor too cold, which is very comfortable!

How's it going? Are these future shoes designed by me simple and practical? Are you tempted? So, what kind of future shoes do you design?

My whimsy 400 words 2 The epidemic has been raging recently, and everyone is in a state of panic and tension. As long as someone sneezes when walking on the road, people will involuntarily look around nervously, fearing that they will accidentally catch germs. In this critical situation, I especially hope that I can invent a machine to protect everyone's health.

I named my imaginary machine "Health Guard". It looks like a street lamp, tall and thin, with a fork at the top, a circular lighting lamp on one fork, and a nozzle dedicated to aerosol on the other fork. It can spray aerosol disinfectant to its lower periphery regularly, and illuminate the periphery when necessary. There is a panic button on its main pole. If there is a special need, people can control it to spray aerosol disinfectant immediately through the button.

During this time, every time I go home, my mother will immediately urge me to take a shower and change my clothes, just for fear of catching the virus. Imagine that if a "little guard" is installed at the entrance of the community, everyone passing by can enjoy the feeling of being disinfected, and at the same time, they can take home the things they bought outside after disinfection, which is very reassuring.

I really hope that my little invention will succeed one day and contribute to maintaining everyone's health!

My whimsical composition in the fourth grade is 400 words and 3 words. Whenever we have an art class or go out to sketch, we always have big bags and small bags, and we also need to bring markers of various paints, materials and colors. We accidentally forgot to bring this and that, so I want to invent a "fantasy marker". Come and listen to my whimsy!

The appearance and material of "magic marker" are similar to those of highlighters we usually use. It is made of plastic, about 15cm long and 1 in diameter. About 5 cm, Tongbai has only two pink buttons. It's small in your hand, and it's cool to turn.

Simple as it is, it's amazing! At the top of the mark, there is a red button. As long as you press it gently, a small screen will appear to select colors. Just enter the color you want on the screen. When you set the color, the screen will shrink back and it will be an ordinary pen again.

At this time, you just need to press and hold another pink button to say the pen you want, such as watercolor pen, oil pastel, highlighter, etc., and the pen you want will stand out at the nib.

It also has a more magical function, that is, it can correct posture. If your posture is not correct, it will automatically retract the pen and stick out its head until your posture is adjusted correctly.

How convenient life would be if you had this pen! Is my whimsy magic?

On Thursday, I was watching TV at home when a robot appeared on the screen. I named him Tinker Bell.

Tinker Bell is cute, chubby figure, chubby big head, a pair of dark eyes embedded in her face, a flat nose, a big mouth with a glib tongue, and she always smiles when she sees people.

Once cleaning, the whole family goes out early and comes back late. It hasn't been cleaned properly for a week. Tinker Bell volunteered to take on the heavy responsibility of cleaning, only to see a broom emerge from its belly and a dustpan spread out. As long as it is a little dirty, it will run to clean, even under the sofa and bed. Wipe it carefully with a rag after sweeping, and the floor suddenly becomes spotless. The magic of Tinker Bell doesn't stop there. Once when my mother was cooking, a lot of fumes made us cough. Tinker bell saw it, opened her mouth and took a drag. All the smoke ran into her mouth. Then she blew hard out of the window, and the hateful smoke was exhausted by Tinker Bell. Soon, the house will be clean and refreshing. I am so happy that I really want to have a warm hug with it.

The magical and clever "Tinker Bell" has helped us a lot and brought joy to me and my family.

My whimsy fourth grade composition 400 words 5 With it, the floor will be clean every day; With it, you don't have to worry about doing a lot of housework a day; With it, you don't have to hesitate how to sort the garbage in your hand; It's a smart trash can.

At this time, you must be wondering, "I have only heard of trash cans, but I have never heard of any smart trash cans." Smart trash can is not an ordinary trash can, it is a small robot. Divided into five grids, representing wet garbage, dry garbage, harmful waste, recyclable garbage and dusty grids respectively; There is a vacuum cleaner, a small mop and four wheels at the bottom. There is also an identification slot and a "hand" with a piece of cloth on it.

It has automatic identification function. When you put the garbage in the identification slot, it will identify what kind of garbage it is and put it in the corresponding grid. If it is multiple pieces of garbage, he will identify them one by one.

It has automatic cleaning function. Walking around the house every day, mopping the floor while vacuuming and putting the dust in the corresponding grid. If garbage is encountered, it will be sent to the corresponding grid through the pipeline.

It also has an automatic sensing function. If it goes to the table, it will pick up a piece of cloth to wipe the table and chairs, put everything on the table in order, and then continue to mop the floor. If it feels the cloth is dirty, it will run to the faucet to wash it and dry it.

Smart trash can can not only automatically identify garbage, but also clean the room, which is really popular!
