As a primary school student, I spend most of the day in front of my desk every day. One day I suddenly had an idea and wanted to invent such a magical smart desk!

This smart desk looks very futuristic: the desktop is made of lightweight and strong high-tech materials; a mini smart sensor device the size of a fingernail is embedded in the upper right corner of the desktop; and a rotatable sensor device is installed in the upper left corner of the desktop. Three-tier cylindrical small bookshelf.

The most amazing thing about this desk is its smart sensing function. Just sit at the desk and touch the desktop sensor device, and the desk will quickly adjust the desktop to the most suitable height for you based on your height. When you write, read or sit in an incorrect posture, the smart sensor will immediately receive it and immediately send out a warm reminder to allow the owner to adjust the sitting posture. Haha, this way my mother no longer has to worry about my sitting posture being wrong!

Another wonderful thing about it is that the bookshelf has automatic organizing and storage functions. Just put the books on the bookshelf, and the organizing and storage work will start, and all the books will be arranged neatly in categories. When you want to take a book, just point your finger at that book, and the bookshelf will automatically push the book out of the shelf for your convenience. Moreover, the bookshelf has endless storage capacity, so it can accommodate no matter how many books you have!

It also has a smart lighting function, which is achieved by connecting a circular smart light source to the bookshelf. When you sit down at the desk, the light source lamp will automatically adjust the brightness according to the indoor environment, effectively protecting your eyes; it will automatically turn off immediately after you leave, and the special light bulb can be used permanently without replacement, which is energy-saving and environmentally friendly.

This is the smart desk in my imagination. How I wish it could be produced soon so that I can experience it myself! A 450-word essay on my whimsical ideas 2

What will the school of the future look like? Let me introduce it to you.

The school in the future will be hundreds of stories high, with canteens, gardens, bedrooms, wards, offices, student offices, computer rooms... everything is available to meet all the needs of teachers and students.

However, how long does it take to climb to the top floor of such a high-rise building? Don’t worry, the school has a light speed elevator, which reaches the speed of light and reaches the top floor in an instant.

Why aren’t the students afraid of heights at such a high place? It turns out that when entering the school, all teachers and students were exposed to the "anti-fear magnetic field", so the students could play easily on it. look! The classmate was about to fall. Suddenly, a blue barrier appeared in front of him and bounced him back. It turns out that the laser protection barrier worked!

The teachers and students in the school are extremely relaxed. Why? Oh, it turns out this is it: teachers teach in a comfortable "teacher's classroom". There are multiple massage systems in the "teacher's classroom", which allow teachers to enjoy massage services while teaching. The class is particularly comfortable. There are multiple massage systems in the student classroom. Computers are N times less harmful to the eyes than original computers. Teachers use computers to teach students through image transmission.

No, I’m not convinced. Why don’t they have homework every day? And our homework stack is "breaking through the sky"! It turns out that the teacher can use the high technology of computers to check your brain and see how well you have mastered undergraduate knowledge. If you have not mastered it, the teacher can add undergraduate knowledge to your brain. If the student has a wrong understanding of the undergraduate knowledge, then Make changes.

The school of the future will have many functions. I believe that such a school will be built in the future! My whimsical composition 450 words 3

Whenever I am not good, my mother will say: "If I don't study hard, I will give birth to another child!" Then, I think: What if If I really had a brother, what would my life be like?

If I had a younger brother, it would be of great benefit to me. Because that way, there will be one more pistachio in our family. When my mother scolded me, I made him cry.

Mom's attention will all fall on her brother. At that time, I could run away. But my mother is definitely not that kind of person. After coaxing her brother, she will definitely come back to "settle accounts" with me. Maybe his younger brother will be there to cheer him on. Dad would also say from the side: "You deserve it!" Forget it, forget it, this is too suspenseful.

However, I can teach my brother arithmetic, literacy and English. In that case, he would look at me with great admiration and say to me: "Brother, you are great!" I felt light and airy. I have fans too!

If I had a younger brother, I would also be a little worried. If there was only one apple, my mother would say to me: "You are older, let him have it." I guess that apple would belong to him. In winter, when the weather got cold, I could only watch my brother sleeping with my mother, while I could only huddle in the bed alone. Thinking of this, I couldn't help but shudder. My mother would also say to me: "You are old, you have to sleep by yourself, my brother is still young." What if my brother pees feces and urine on his pants when my mother is not around? I'm not only afraid of hurting him, but also afraid that it won't be clean, plus it smells... woohoo! It's so disgusting, I can't even imagine it.

Suddenly, my eyes became a little wet. It turns out that it is so difficult for my parents to raise me! I feel that my parents have put a lot of effort and love into me, just like an older brother takes care of his younger brother. When they grow old, I will take care of them just like they take care of me. Who makes me the elder brother? A 450-word essay on my whimsical thoughts 4

It is a very commonly used thing, used by both the elderly and children. It is a magical water glass.

The color and shape of the water cup can be adjusted at will, and it is made of a special material. The water cup is particularly comfortable. It has two plant buttons, lotus and plum blossom, representing different seasons, as well as two buttons with the words "big" and "small" written on them.

This water cup can adjust the water temperature and cup temperature according to the season and temperature. In the bitterly cold winter, if you press the plum blossom, it can automatically adjust the water temperature to heat the water, and it can also heat the cup, like a warm baby; in the hot summer, press the lotus flower, and it will become a little cooler. The cup also gets cold, so you can put it close to your face to cool down after gym class.

The "big" and "small" buttons on the water cup are used to control the size of the water cup. If you go out for a trip, picnic, or spring outing, press the "small" button and it will become the size of a mobile phone, making it easy to carry; if you are going to class or working, press the "large" button, and it will become the size of a water bottle. It is large, so the amount of water is enough for a day, and it can also keep it warm.

It can also hold food. If you buy an ice cream outside but don’t want to eat it now, you can put it in a glass of water so that it won’t melt; similarly, if you buy food that is delicious only when it is hot, put the food in a glass of water. It can keep food warm and prevent it from getting cold. But only if the water is finished.

Students, I believe that in the near future, my smart water cup can become a reality, and everyone’s fantastic ideas can also become a reality! A 450-word composition about my whimsical thoughts 5

Welcome home! One afternoon in 20xx, as soon as I returned home, the automatic recognition device installed on the door recognized me, opened the door automatically, and greeted me warmly.

When I got home, I pointed my hand towards the lamp, and the lamp flickered on. I pointed my hand toward the curtain, and the curtain slowly closed toward the middle. The indoor light appears softer. I sat down on the sofa in the living room and pressed a book-shaped button. Three large bookshelves filled with world famous books immediately appeared in front of me. I picked a book "The Romance of the Three Kingdoms" and read it carefully. Have some orange juice! As soon as he finished speaking, a robot immediately brought a glass of warm orange juice. After drinking the juice, I put the book back on the bookshelf, and the bookshelf disappeared.

On Sunday, I turned on the flight mode, and a propeller slowly stretched out from the roof. As the blades rotated, the house slowly rose. I wrote the words Shibawan on the screen on the coffee table. After a few minutes, the house had reached the picturesque countryside. No more traffic jams like before, no need to carry big and small bags everywhere. The curtains on the walls of the house were slowly retracted, and the surrounding area turned into a sunroom covered entirely with glass. I opened a few windows, and the cool wind and the fragrance of wild flowers slowly blew in, which was refreshing. I couldn't help but take out the paper and pen and start drawing.

As night fell, I fell into a sweet dreamland in the cozy flying house. Thanks to technological progress, now I no longer have to stay in a hotel when traveling!

The next day, the house was back to its original place. I start my day and immerse myself in my writing. My whimsical composition, 450 words 6

Recently, the new coronavirus has invaded mankind on a large scale. Large numbers of people are infected every day, and the hospitals are full of patients. Even if doctors and nurses are wearing protective clothing, masks, hats and goggles when treating patients, they are always at risk of being infected. Looking at the news in newspapers and on TV, I thought to myself, if there was a doctor robot that could replace doctors and nurses, it would be great!

This robot looks like a square iron frame with a mechanical arm on the left and right sides. There are many medicines and medical equipment on the shelf. It has four wheels on the bottom and can be moved freely. Of course, its CPU is connected to the doctor's workstation, and only doctors and nurses can control the robot. Because the set program is installed in its CPU, it can treat patients like a skilled old doctor.

After the robot doctor enters the ward, based on the patient's heartbeat, respiratory rate, body temperature and other data, he analyzes the patient's condition by asking the patient about his or her own feelings, and proposes a treatment plan for the day. It also performs the work of a nurse, giving injections and medicines to patients. If the patient wants to eat but is inconvenient to get it, its two long robotic arms can do the job for him. Patients will inevitably feel lonely when they are alone in the ward for a long time. When they are depressed, the robot turns into a close sister, patiently talking and chatting with the patient, or allowing the patient to video chat with their family members to help them feel happy and rebuild. Confidence to overcome disease. Under the careful care of the robot, the patient can recover and be discharged soon.

The emergence of doctor robots can not only prevent doctors and nurses from being infected by the virus in close contact with patients, but also share part of the work, making the work of doctors and nurses less hard. It really kills two birds with one stone. A 450-word essay about my whimsical thoughts 7

I am a fourth grade student in primary school. I have many ideas. What I wanted to be the most was a reporter, because reporters can bring some information to society. Very unfair things were reported. But since the May 12 earthquake, seeing so many people suffering has made me feel very sad.

So, I thought, I will study hard and become a scientist in the future, and then I will develop a very special house. The house I developed is very light and does not use cement and steel bars, because cement and steel bars are very light. It is bulky and cannot be moved in the event of an earthquake or flood, and it is easy to hurt people. The house I developed is made of raw materials that are made of some ordinary domestic garbage that has been sterilized and treated without pollution. It cannot be blown away by strong winds because there are special materials stuck to the soil under the "feet" of the house. If there is a flood, the house will float on the water. When the water recedes, it will return to the same place. When an earthquake comes, it will not collapse like the house we live in now because it is very light. , it is also very strong and will not hurt people. This is the house I want to develop. It is not expensive to build and can be lived in by both ordinary people and wealthy families. It is also environmentally friendly and saves resources.

If we encounter another earthquake like 5.12, we humans will escape a lot of misfortune, and our tragedy will not happen again.

This is my fantastic idea. I hope that through our human efforts, it can be realized. This is my dream and wish as a fourth grade primary school student! My whimsical composition 450 words 8

I want to be an inventor and design a magical car.

The outer shell of the car is covered with green environmentally friendly paint. The tires of the car are wear-resistant and made of environmentally friendly materials and will not emit odor due to high temperatures. Open the car door and you will find that it has a simple console with many buttons and a steering wheel. In addition, it also has a small and exquisite controller with a megaphone on it. The owner only needs to speak the license plate number of his car. No matter where you are, it will be there for you.

This kind of car can not only drive on the ground, but also extend its legs to climb mountains. If necessary, it can be sucked onto the wall, eliminating the need for a parking lot at all.

It can install a drill bit in front of the car to drill into the ground, it can float on the water and sail, it can dive into the seabed thousands of meters or tens of thousands of meters deep, and it can also swim in space.

The car I invented achieved a very important point, which is energy saving, emission reduction and zero pollution. There is a large bottle of "super energy-saving oil" in the car. You only need to pour a drop of this oil into the fuel tank, and you can travel five thousand kilometers without making any sound. The car has no exhaust pipe, only a small box, and you spray it from the box. Breathing out fresh and sweet air.

There is also a door, inside which is the driver's cab. There is a homemade VK computer on the table with all the functions. Below is the steering wheel. With these, you can go wherever you want, and you can also go to the deep sea and the universe! Driving at supersonic speed!

Hey, after all that, have you fallen in love with my Sky House? A 450-word essay on my whimsical thoughts 9

As the age increases, some people’s memory gradually declines. What they did today will be forgotten the next day, even what happened in the morning. I might have forgotten about it in the afternoon. My grandparents were like this. They just promised me and my sister yesterday and forgot about it in the blink of an eye. Seeing their frowning memories, I felt very uncomfortable and wanted to help them.

Therefore, I want to invent a necklace that can store memories to help the elderly who have memory problems like them.

This necklace is composed of a thick, long chain and a very exquisite and delicate small bag. The chain is engraved with lifelike twelve zodiac signs, and right below the chain hangs a small bag. There are exquisite little wings on both sides of the small bag, and there are small buttons on the small wings. There are three different buttons on the small wing on the left, and a voice button on the small wing on the right. The body of the small bag is covered with simple patterns, which is eye-catching.

As long as this small bag feels memory energy, it will automatically open and absorb the memory energy. It also differentiates between good memories and painful memories, as well as ordinary memories. It puts good memories at the top, ordinary memories in the middle, and painful memories at the bottom. When you want to recall the memory of a certain day, just enter your voice and tell it your request, and it will appear in your mind in the form of a projection. Once it is finished playing, it will be automatically put back in the bag. Of course, if you want to delete certain memories, you can also delete them through voice.

Do you remember those three buttons on the wings? They certainly have their functions. The three buttons are the blue button that represents volume increase, the red button that represents volume decrease, and finally the green button that can convert Mandarin into dialect. This is considering that some elderly people may not understand Mandarin. This button can be used to convert Mandarin into a language they can understand.

I really hope that this kind of necklace can be realized one day in the future to help those elderly people in need! My whimsical composition 450 words 10

Our real houses are just ordinary square ones. But that's boring, so I'm going to invent a weird house.

This kind of house has a variety of shapes, and it can become whatever you want it to be. What kind of fruits, big trees, shoes, etc., as you wish!

This kind of house can not only change its shape, but also be enlarged and reduced. As long as you press the blue button, it will become larger, the red button will become smaller, and the yellow button will be medium.

There are actually two more peculiar functions. There is a robot hand in each cabinet. If something falls, they will immediately sense it and catch it in time, and even It’s amazing how you can pick up broken things perfectly!

My favorites are the nano walls and nano roof, which use solar energy to automatically adjust the temperature throughout the year, saving air conditioning and heating. The most unexpected thing is that by pressing the purple button, the entire house made of nanotechnology will show a dynamic scene. You can travel happily in space, learn about each planet, play with animals in the forest or defeat ferocious monsters. As a carnivore, I would have dinner with country people in the countryside and look out at the beautiful scenery on the hillside. It was really fun.

It took me a long, long time to realize that this was an illusion, this idea was an illusion, and I was completely intoxicated. It was so real and shocking!

After returning from imagination to reality, I can realize that only by studying hard can we invent or even live in a house like that. Let’s work hard together! A 450-word essay about my whimsical thoughts 11

With the development of science and technology, big data, cloud computing, and the Internet of Things, our lives have undergone earth-shaking changes in terms of food, clothing, housing, and transportation. The development of science and technology has also inspired With my imagination, I often have many fantastic ideas. My fantastic idea is to invent a smart rainfall system.

In the past few years, the north has been dry and rarely rains. Drought has many hazards, such as turbid air, cracked land, withered plants, and even difficulty in drinking water. If there is an intelligent rainfall system, these problems can be solved.

This intelligent rainfall system is like a circular UFO with a diameter of one hundred kilometers, a jet hole on the top, a wind tunnel on the side, four wings, and four wheels on the bottom. When floating in the sky, the wheels and wings will be retracted. Its material is an active high-temperature resistant resin, which is transparent when floating in the sky. This rainfall system has many functions, including weather forecasting system, rainfall distribution system, smog cleaning system, etc. It can accurately predict weather, measure air humidity and air quality, and collect various weather-related data to determine where drought is. How much rainfall is required. Its most powerful feature is the rainfall distribution system.

There are often heavy rains in summer in southern my country, and floods sometimes occur. In the north, the sun is shining brightly and it is prone to drought. At this time, the intelligent rainfall system will fly to the south, use the spray hole on the top to spray ecological quick-freezing liquid to turn the rain clouds into solid, and then use the wind tunnel to blow the rain clouds over the arid north. At this time, the injection holes will spray thawing fluid again, and it will rain in the north. Don't worry about flooding, the smart rainfall system will determine how much rain will fall based on drought conditions. In this way, there will be no floods in the south, no drought in the north, and good weather everywhere.

How about this smart rainfall system? Isn’t it amazing? A 450-word essay on my whimsical thoughts 12

"Oh my god! My things have been rummaged through by others again. It would be great if there was a lockable desk." Li Shan saw His face drooped again as his desk was turned over in a mess. Haha, I have never encountered this situation because I have a multifunctional desk that I invented.

My desk looks the same as other desks, but it has many functions. There is actually an invisible door hidden next to the desk, and there is a password on the invisible door. When someone wants to put their hands into your desk, the desk will close the invisible door so that others can't open it no matter how hard they hit it. But what if you forget your password due to brain short circuit? Then this multifunctional desk will activate the face-scanning mode to detect whether you are its owner.

My desk will remind you to pay attention in class. There is also a monitor next to this multifunctional desk. As long as you are not serious in class, the monitor will make a sound like an alarm, which will be heard by the teacher and make you feel ashamed, so that you will not be able to doze off during class.

My desk can also help you look up information. When you encounter a problem that you don't understand, just write it down on the touch screen of the desk and it will help you solve all the problems. It is like a big treasure box containing many treasures of knowledge. When I seek knowledge, it always provides "knowledge nutrition" to my brain in time, allowing my brain to continuously upgrade every day.

This is my desk, which is both my learning partner and my childhood teacher. My whimsical composition 450 words 13

I want to invent a magical dress.

The clothes are made of nanomaterials, with a card slot reserved for installing high-tech chips. The changes in nanomaterials are controlled through the chip, and the size and color of the clothes can be changed at will as needed.

If this piece of clothing can only change size and color at will, it cannot be called a magical piece of clothing. It has many practical functions. For example, when we encounter a car running a red light when crossing the road, the sensor on our clothes will immediately transmit information to the chip at the moment we are about to hit it. The chip will control the clothes to inflate an air bag instantly, so that we will not be injured even if we are hit. . This function is used when drowning, so that no one will drown because they cannot swim.

Clothes also have the functions of fire prevention, heat insulation, and automatic repair. In the event of a fire, the clothes will wrap our whole body and form a mask on the head, filtering out toxic gases and allowing us to breathe normally without affecting our vision. The heat insulation function of the clothes prevents us from being burned by high temperatures. When the clothes are scratched by something sharp and hard, the automatic repair function will be turned on and the clothes will be repaired instantly. In addition to these practical functions, there are many other functions, so I won’t introduce them one by one.

Many accidents happen every day in life. If our fire rescue personnel wear these clothes, they can better protect their own safety while rescuing others. If everyone could have such a piece of clothing, many tragedies would be prevented and people could spend every day happily.

The clothes I want to invent are magical. I hope that one day I can invent it and benefit the world. A 450-word essay on my whimsical thoughts 14

In the 35th century, humans invented a piece of clothing that seemed to be very ordinary, but its function was extraordinary, and it could be called a Complete, very popular.

When you put it on, you will notice at first glance that there are several different buttons on it. As long as you press the rectangular button, the clothes will quickly send a small note to you. In your hand, there are detailed instructions for using this piece of clothing. As long as you press the red button, this piece of clothing will quickly measure the temperature of your environment and automatically release the appropriate hot and cold temperature according to the actual temperature. The air is used to balance the air temperature so that you feel that the surrounding temperature is always a constant temperature. When you press the yellow button, your body will slowly rise to a certain level and fly to where you want to go at a very fast speed. , this kind of transportation is both environmentally friendly and safe, and can give you 100 peace of mind. If you press the green button, your clothes will immediately turn into a space suit, and then you will fly into space like a rocket. In space, it can also provide you with various information about the planet and automatically take you there. Go to all kinds of planets you want to play.

If you press the black button, a robot will run to you quickly, and then you just need to tell her what you need? She will quickly help you complete the tasks you give her on time. You can also chat with her as a robot, and she will become your inseparable good friend.

Aren’t these clothes very convenient? Let us come together and fight for this! A 450-word essay on my whimsical ideas 15
