In study, work and even life, everyone is familiar with composition. With the help of composition, people can achieve the purpose of cultural exchange. In order to make your writing easier and more convenient, the following is my fantastic fourth-grade composition, hoping to help you. My whimsy composition 1

Every time it rains, my young master's classmate on duty will hold a broom, an umbrella and a garbage bucket at the same time, so it is inconvenient for both hands to take three things at once. So my master wanted to invent a magical object to solve these troubles, so I was born. My name is "umbrella broom", and I am a combination of umbrella and broom.

Me, my body is made of carbon nanotubes. Carbon nanotubes are amazing, and they are 1 times stronger than steel and much lighter than iron. Me, I opened my "little hat" according to the weather change! As long as the weather is fine, the "little hat" will be closed. If it happens to rain, my "little hat" will automatically open and open an umbrella for my classmates under the "little hat", so there is no need to worry about not having enough hands and getting wet.

do you want to know why I knew it would rain? Because my "little hat" has a three-layer triangular sharp corner, the lower two layers are short, and the upper layer is tall and sharp. This is my "super weather detector".

This is "me"-a magical and easy-to-use umbrella broom. My whimsy composition 2

Everyone in the future has a multifunctional machine book. Let me explain its function.

it can be taken with you, because it can be as small as a nanometer when you are not using it. All you have to do is say minimum, and then put it in your pocket.

To tell you quietly, 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 needs 1 yuan. It has many functions.

if you accidentally lose it, you just have to say, "come back with the multifunctional machine book." It only takes less than . 1 seconds will come to you, no matter how far it is, it will come back at the same speed.

Ordinary books get wet in water and turn to ashes in fire, but my multifunctional machine book is invincible, and it is hundreds of millions of times stronger than that steel bar. Am I awesome? 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 turned into a Sherlock Holmes. Good god, then I look with relish.

The multifunctional machine book has another function, that is, if you read for more than 4 minutes, it will automatically close, so that your eyes can have a rest, and there are many irregular reading, which will remind you that there will definitely be fewer people with myopia.

I only introduced one percent of the functions. If you want to buy it, you only need 1 yuan to read books for life. What are you thinking? Come and order. My whimsy fourth grade composition 3

In the future, I invented a multifunctional walking shoe.

multifunctional walking shoes are shoes that can walk on the ground, swim in the water and fly in the sky.

This kind of shoes looks just like ordinary shoes, but what's the difference between them? Let's have a look.

It turns out that the soles of these shoes are made of nanotechnology, which is so small that water molecules can't penetrate it. Therefore, people wearing these shoes can naturally walk on the water.

If you want to go to a popular scenic spot with too many people, then you can start the flight mode of multifunctional walking shoes. As long as you press the blue button on the shoes, a pile of water vapor will be ejected from the soles, which will soon condense into clouds. These clouds are not ordinary clouds. You can stand on them, and then the clouds can take you where you want to go.

In short, with my invention, people's lives have been greatly improved. I hope I can invent more things to help people's lives in the future. My whimsy 4

In the world, it would be nice if there was a bug that could eat advertisements. Its shape is very similar to that of a scorpion, except 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 put this bug on it. It only takes one minute, and the small advertisement disappears without any residue.

I hope there is a kind of garbage-eating bug, which 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 the bugs on the garbage, and the garbage will disappear in a few seconds.

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

I also hope to have 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 a waste glass bottle to dispose of, I can put this bug in it and eat it all in 5 minutes.

I also hope ... my whimsy composition 5

Since ancient times, clothes have been so important to human beings, but they are too easy to get dirty, and they can't be worn soon, and they can't keep up with the trend. In the end, I have to buy a lot of clothes. The old ones don't fit well, and the ones that fit well don't look good, so I invented this cloak.

when the function is not used, the cloak is big red, with a column of blue gems in the middle and a gold pattern around the edge.

this cloak is suitable for everyone, and it can change with the owner's body in a humanized way. This cloak looks cool and mysterious. At the same time, there is also a lot of privacy, and there is a pocket inside, and you can order artificial intelligence-cloak No.1 to "put on one" to help you stretch or compress the pocket. Many items can be stored in it, but the weight and size will be compressed to one thousandth, and you can return to the original state by calling "put on one".

In winter, the cloak will be heated, and the temperature can be well controlled. In summer, the cloak will have many tiny holes, which will help to ventilate and make people feel no heat.

When exercising, the cloak will become looser and shorter, and it will sweat strongly and protect the joints.

When you get lost, Piyi will stand up and use the navigation function to choose a safe way to protect you from going home.

When you are in a hurry to get home and there is a traffic jam, you can also use its flight function to avoid the crowd, go ahead quickly and do what you want.

Science and technology have enabled human beings to escape from the sky. Future science and technology will definitely break all the impossibilities, turn them into possibilities, or create new glories. My whimsy 4 th grade composition 6

In 2179, with the rapid development of science and technology, many new things appeared in our field of vision and changed our lives.

Look, there are many kinds of clothes. It can change colors according to people's mood. It can predict the weather and change different styles of clothes, such as: in summer, if the owner feels cold, it will automatically extend the half sleeves; On the contrary, it becomes shorter. In different places, there will be different patterns. For example, when you are in Crescent Spring in Xinjiang, there will be boundless deserts and tall camels on the clothes. In Kanas Park, the patterns on clothes will automatically become flowing rivers, and there will be boats. What a fantastic dress!

Look, there are green and pollution-free foods. Grilled fish, hand-grabbed rice, pineapple beer drinks, fresh and delicious grapes in the grape valley, and sweet and crisp cantaloupe produced in Hami ... There are all kinds of delicious foods in the world, and you can eat as much as you want. After eating, they can grow new ones, which will never be exhausted. You don't have to worry about getting fat and getting sick if you eat too much. It's all natural green food and won't do any harm.

Look, there are luxury apartment buildings, which read: Bao Building, Li Building, Wang Building ... All of them live in their own families.

Life is so convenient now that I can't bear to leave 2179. My whimsy fourth grade composition 7

Hello, everyone, I am a "changeable mask". Let me introduce myself to you! My functions are many and amazing.

As for my appearance, it's hard to say. People always say that I look a little cute, but I think I'm not cute. I'm "cold" and a "cold mask".

One afternoon, my master wanted to go to a place to play, but he went out late and was about to be late. At this moment, my master thought of me, and as soon as I put it on, I became a flash, and I went to my destination with a whoosh.

I just forgot to mention that I can not only become a person, but also make any small object you want, even a book, which can be made by just touching it gently.

When I was at school, my master found that I had forgotten a book, but it was too late, because he couldn't go out when he got to school. At this moment, my master remembered me, and I immediately became a book, so as to avoid the teacher's blame.

This is me, a changeable mask. After listening to my introduction, are you eager to see me in your life? My whimsy 4 th grade composition 8

Now the traffic is very crowded, I want to invent a motorcycle that will not be stuck in traffic jams, and it is also green and anti-theft-smart motorcycle.

The appearance of smart motorcycle is similar to that of ordinary motorcycle, except that a blue button and an alarm are added. 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 be stuck as soon as he touches a motorcycle, and the alarm will sound an alarm. Motorcycle is made of a special kind of metal, which is very strong. Behind the seat is a big box with a pair of wings inside, which will automatically stretch out when you press the button. Above is an alarm, which can not only alarm but also absorb solar energy as the power of motorcycle; Not only can it absorb solar energy, but it can also absorb the energy of the moon and store it. The motorcycle also has a fingerprint lock, which can be automatically unlocked as long as the owner presses it. Its name is smart motorcycle.

If everyone has such an intelligent motorcycle, they will no longer be afraid of traffic jams or thieves coming to steal it, and it will be environmentally friendly and save energy. My whimsy composition 9

The operation method of this car is very simple. Even if I can't drive, I can easily control it. Just say the name of the place I want to go, and it will automatically drive and lead you to the destination.

There is an automatic temperature control system in the car. In summer, after getting on the bus, the temperature in the car is about to reach 22-24 degrees, and the sweet and delicious ice cream in the cone cabinet is smiling at me happily. In winter, when the temperature inside the car rises to 1-15 degrees, the milk tea cabinet will quickly produce a steaming cup of fragrant milk tea and send it to your mouth.

the food cooked by the car is delicious. Today, when I got into the car, the car saw through my mind and prepared me a "delicious meal"-sweet and sour pork ribs. The attractive aroma came to my nose, and I gulped it down and soon it was swept away by me.

My car will become a home robot, and he knows everything. Today, my mother told me to tidy up the room. I took a look at the room-what a mess! So, I used my secret weapon-the car home robot, which can clean the house in a few minutes. My mother came back and looked at me with new eyes, so I became a "little housework expert" at home!

A car is my most important partner! One day in the year 12
