"It stinks! So much rubbish! " "Why is there so much smoke? I can't walk there! " "A-choo." "ah! The child is ill ... "People are talking about it. It seems that the dirty and smelly environment is really harmful to people. Ha ha! No problem, on the environmental robot.

It has red and blue buttons on its head and red and blue small backpack on its back. If you press the red button, you will put the garbage within 10 meters around the robot into the red backpack. If you press the blue button, you can collect all the air smoke around the robot in the blue backpack 10 meter. You must think, what if the backpack is full? Don't worry, there is a thin and long needle in the center of the robot's head. Don't underestimate this needle, it uses it to remove waste! It can turn all waste into dense trees, fragrant flowers, or clear rivers and green grasslands. Those small and exquisite eyes-they scare you, they can emit a special kind of light, which can destroy bacteria within100000 kilometers around the robot at once. It has many thorns on its stomach, so it can spray fragrance from time to time to make the air fresh. Oh! I forgot to mention that there is something called a vacuum tube on my hands, which can "swallow" the exhaust gas from the rear of the car and then "eat" it to turn this gas into electricity. And its feet, where you have stepped, will be clean without any stains.

How about an environmentally friendly robot that brings comfort to people's lives?

My Invention-Colored Wall

In an instant, 20 years have passed. I have become a world-class doctor and won N Nobel Prizes. This year, I invented a new product-"color wall".

This colorful wall can be used in schools, and it will change its temperature and color with the corresponding environment and time.

After class is over, the most important thing for students is to have a rest, and then have a rest, so that they can have a good next class. Therefore, the "painted wall" will turn into fresh green, so that students can completely relax. In addition, the "color wall" will also emit a microwave after class. As soon as this kind of microwave enters students' eyes, it will give them a "microwave massage", which is equivalent to an advanced "eye exercise"

Of course, "painted walls" are indispensable in summer. Because in summer, the "painted wall" will automatically turn blue, which makes the students feel "cool" immediately after reading it. Not only that, as long as the "painted wall" absorbs a certain amount of heat, it will automatically spray cold air, so that students can also blow a cool breeze in hot summer.

It is also an indispensable helper for students to take exams. Students must be a little nervous during the exam. At this time, the "color wall" plays its color-changing function, turning the wall into orange, making students relatively relaxed during the exam, thus ensuring that students get good grades in the exam.

Look! This is my invention.

What I want to invent most is

Scientists nowadays are too good at inventing interesting things! They keep discovering and inventing. One of them is a pen. What's so special about pens? Someone will ask this question. I think the person who has this problem must be a curious person. I can answer this question! Although writing with a pen is very simple, it contains many special functions, which are different from other pens. If you want to know, please read my introduction!

The material of this pen is exquisite and special. Because this pen is made of crystal. Someone asked, "What, what? Crystal in crystal? Can also be used to make pens? Isn't this ridiculous? " Hey hey! Actually, it's not funny at all. It's just that you are a little surprised that this exquisite pen is carefully processed.

Don't underestimate this pen, it is the most advanced pen, and it has many functions! Hee hee!

This pen is a teacher. Why do you say "teacher"? This is its function! For example, one day, you are reading English, and it is right next to you. If there is anything wrong, it will be recorded, then played back and read to you correctly. If you don't study hard, it will explode!

It can also become bigger or smaller, bigger: as big as a building. Become as small as an ant.

This pen also has a beautiful computer. Very advanced! Don't use it in math class, if you do. It will automatically close for a week. It's really serious. Be careful.

If you get lost in the desert, take it out. It will help you find your way home and find enough water in the desert.

Can also become a ship, although the ship can't cross the sea. But this boat with a new pen can cross the sea without encountering all kinds of dangers.

Therefore, this pen has a nice nickname! Little teacher, tape recorder ...

But this kind of pen has not been produced yet, and I think it will be invented in the future.

What composition do I want to invent?

What will the weather be like tomorrow? It must be wonderful. I have pondered over the future of my motherland.

In the beautiful days to come, the house where we live will also undergo great changes.

People no longer live in unit houses, but in luxury villas that can be downgraded and upgraded.

On the surface, it is just a garden surrounded by a fence.

However, as long as you walk through the gate, it will automatically issue instructions: "Hello, please enter your fingerprint.

"If the fingerprints match, the grass under your feet will automatically sink and then be taken to the living room.

If you are a stranger, the door will open automatically as long as the host knows you.

If it is a thief, he will call the police automatically.

The recognizer will start the anti-theft system and catch the thief with a laser.

In every house, there is a multifunctional robot, which does all the housework and even boils water for cooking.

As long as you give the order one hour before work.

When you get home from work, a steaming big dinner is already waiting for you.

Every Mid-Autumn Festival, you only need to recite the poem Gulangyu written by Li Bai.

The horse rose to the sky and went straight to the moon.

At this time, a large multifunctional stage appeared next to the osmanthus tree in the Moon Palace. Chang 'e stretched her long sleeves, performed a break dance and tasted wine in WU GANG.

And the moon rabbit clamored to come to earth to play with the owner of the house.

In addition, the house has a more peculiar function! It will play different music according to the owner's mood, and adjust the indoor temperature and the color of the wall according to the weather temperature.

As long as we study hard on scientific and cultural knowledge, the motherland's tomorrow will be beautiful.

Today's fantasy will definitely become a reality in the future.

Our tomorrow will be more brilliant! The enlightenment of birds is well known.

Birds also have a special function, which is to inspire human wisdom and provide principles and blueprints for human beings to explore ideal technical devices or vehicles.

It can be said that birds are human teachers in structure, function and communication, and scientists often need to ask birds many modern scientific and technological questions.

Eagles hit the sky, pigeons soar in Wan Li, and birds can fly freely in the air. How attractive and inspiring it is! Legend has it that more than 2,000 years ago, China famous craftsman Lu Ban studied and made wooden birds.

According to historical documents, more than 900 years ago, people in China tied birds' feathers together to make wings that could glide 100.

More than 400 years ago, Italian Leonardo da Vinci designed a flapping-wing plane based on his observation and research on birds, trying to fly with the movement of pedals.

Later, after many scientists' experiments, people understood the mechanism of fixed-wing gliding of birds, and realized that the wing must be as thick as the bird's wing, with a thick leading edge and a thin trailing edge, in order to form a curved surface and generate lift. In addition, the industry provided light metal materials and high-power engines, and finally the airplane was invented in 1903, which realized the ideal that human beings longed to fly into the sky for thousands of years.

Since human beings invented the plane and flew into the sky, they have been constantly innovating the plane, and they have quickly surpassed birds in size, load and speed.

Modern airplanes have flown faster, farther and higher than any kind of birds, especially in recent years, all kinds of airplanes can sail between stars, which birds can't reach.

Nevertheless, in some flying techniques and aircraft structures, man-made aircraft are still not as perfect and exquisite as birds, not to mention energy consumption.

For example, golden pheasant can fly more than 4000 kilometers over the ocean without losing 60 grams. If the plane can fly at this efficiency, it will save a lot of fuel.

Birds' wings have many special functions and structures, which make them not only good at flying, but also perform many "stunts" that are difficult for human technology to achieve at present.

Hummingbird is a "helicopter" among birds. It can take off and land vertically and fly backwards.

When sucking nectar, it does not stop on the flower like a bee, but hovers in the air.

What a clever flight this is.

It has become the dream of many aircraft designers to make vertical take-off and landing aircraft with hummingbird flight characteristics.

The eagle's eyes are extremely keen.

Eagles flying at an altitude of two or three kilometers can find rabbits and mice from many relatively moving scenes by scanning the ground with their eyes, and dive down quickly to catch them at one stroke.

Hawkeye also has the characteristics of sensitivity to moving targets and rapid adjustment, and can accurately identify targets.

With the development of modern electro-optical technology, it is possible for us to study a system similar to Hawkeye, which can help pilots identify ground targets and control missiles at the same time.

The migration distance of migratory birds ranges from several hundred kilometers to several thousand kilometers.

However, they can always reach the destination chosen by generations accurately.

This shows that migratory birds have good navigation ability.

Scientists have studied these phenomena and believe that birds have good navigation ability because they all have their own special sensory organs, which can feel and analyze the changes of environmental factors in different regions of nature, so as to identify the direction and find the migration route.

Some rely on identifying the position of the sun and using the sun as a direction marker; Some use astrology to navigate by identifying the orientation of the stars; Some rely on sensing changes in the earth's magnetic field and using geomagnetic navigation; Others use the earth's gravity field to navigate.

After understanding the principle of bird navigation, bionics and designers can imitate and manufacture all kinds of small and reliable navigation instruments and make contributions to the development of aviation and navigation.

Inspired by penguins, people designed a new type of car-"Penguin brand polar off-road vehicle".

This kind of car is stuck on the snow surface with wide bottom and pushed forward with a wheel spoon, which not only solves the polar transportation problem, but also can drive in muddy areas.

In addition, the unique physiological structure and function of birds also provide many bionics topics for the innovation of mechanical systems, instruments and equipment, building structures and technological processes.

Therefore, birds are both friends and teachers of human beings.

For the future of science and the happiness of mankind, we should also take good care of birds.

Birds give us a lot of priceless inspiration: when people see birds in the sky, they will think of a machine that can take us flying in the sky … an airplane; The mountain carving flew to the ground in an instant. ...

I want to invent a 500-word composition.

I want to invent the shoes of the future-XC-Feifei Attached: If you have any other composition questions, please call me. I am anxious to upgrade. Time flies, and it has been 3059 years in a blink of an eye.

In the past 1000 years, scientists have successively developed PX- Xunsheng train, CX- Blast plane and PC- Shunshui submarine.

And other high-tech products.

But with people's life getting better and better, people feel too much trouble and want to own a 3-and 1 vehicle.

I just want to invent a shoe with the same function.

This kind of shoes is called XC-Feifei, which is made from spare parts and original parts of high-tech products from Xunsheng, Gao Feng and Shunshui for three centuries.

Its accuracy is not just random jumping.

Please omit it.

The first function is heaven. All you have to do is put on these shoes and shout at them, "Explosion, fly!" " Shoes will immediately become bigger, big enough to accommodate you.

Where you are talking about, the shoes will close by themselves.

If you want to read a book or have a rest, just say "rest" and he will provide something.

There should be a small box for storing things below, which is usually invisible.

In addition, the downstream function is similar to this, except that the password is: "Downstream, dive!" " "Then there is a different place.

The third function is floating, and this function is even more' fun'.

Just say, "Xun Sheng, go! Shoes will float 25 cm above the ground.

When you say your destination, shoes will pop out of your seat and take you away.

You don't have to worry about running out of energy at all, because the whole system is solar, and it will store enough energy for flying at night during the day.

This kind of shoes are also divided into' rent' and' buyout'.

Buy-out' is paid directly in one lump sum, and you can enjoy these functions without paying.

"Rent" means to pay every time you arrive at your destination.

However, how to pay? It doesn't matter, you don't have to go to the center to pay in person, because when you arrive at your destination, the shoes will produce a small mouth to fill in the money and tell you how much the trip cost. You put the money in the small mouth and it will be sent to the center. If there is a balance, it will be sent back.

What, do you want to "buy" or "rent"?

One thing I want to invent most is a 250-word composition.

I want to invent an environmental protection robot "stinks!" So much rubbish! " "Why is there so much smoke? I can't walk there! " "Ah, several.

""ah! The children are sick ... "People are talking about it. It seems that the dirty and smelly environment is really harmful to people.

Ha ha! No problem, on the environmental robot.

It has red and blue buttons on its head and red and blue small backpack on its back. If you press the red button, you will put the garbage within 10 meters around the robot into the red backpack. If you press the blue button, you can collect all the air smoke around the robot in the blue backpack 10 meter. You must think, what if the backpack is full? Don't worry, there is a thin and long needle in the center of the robot's head. Don't underestimate this needle, it uses it to remove waste! It can turn all waste into dense trees, fragrant flowers, or clear rivers and green grasslands.

Those small and exquisite eyes-they scare you, they can emit a special kind of light, which can destroy bacteria within100000 kilometers around the robot at once.

It has many thorns on its stomach, so it can spray fragrance from time to time to make the air fresh.

Oh! I forgot to mention that there is something called a vacuum tube on my hands, which can "swallow" the exhaust gas from the rear of the car and then "eat" it to turn this gas into electricity.

And its feet, where you have stepped, will be clean without any stains.

How about an environmentally friendly robot that brings comfort to people's lives?

How about an environmentally friendly robot that brings comfort to people's lives? ...

One thing I want to invent most is a composition of about 200 words.

I am a person who wants to be an inventor when I grow up. I want to invent a door when I grow up. The name of this door is "Universal Door". The purpose of the universal door is to open it with a key. If you forget your key, you can open it with your fingerprint. If your hand is rotten, you can open it with a password. If you forget your password, you can open it with a card. If you forget your card, you can also open it with ultrasound.

If there is a thief's universal door, it can also automatically call the police, and an iron fist will be stretched out next to it to beat the thief. After the fight, an iron net will pop up to catch the thief and wait for the police to catch it.

I also want to invent a robot that can help you cook, wash clothes and buy food ... If you are sick, it will automatically dial 120.

If there is a thief, he will call the police, he will fight with the thief ... he will also accompany you to play chess, do sports and practice martial arts ... I like inventing things very much and envy scientists and inventors.

Elementary school composition: what I want to invent?

Topic: "The Robot I Want to Invent" With the development of science and technology, robots in the future will more and more help humans accomplish tasks that humans cannot accomplish themselves.

Nowadays, with the improvement of people's living standards, excess nutrients such as fat accumulate in people's blood vessels. After a long time, just like the silt in the river, people's blood vessels become narrower and narrower, and some even become completely blocked.

In this way, with the above situation, people's blood pressure will rise, and some even have blood vessels blocked.

Because of high blood pressure, some capillaries in hair are broken, and bleeding spots occur in the brain, which will threaten people's lives.

Because the brain is the nerve center of human beings, once the cranial nerves are oppressed by cerebrovascular hemorrhage, it will be life-threatening if it is not treated in time.

Some patients may suffer from the sequelae of falling into the lower body even if they are treated in time.

Therefore, in the future, I want to invent a very, very small robot, which can go deep into every capillary of people, just like excavators and bulldozers dredging rivers, to clean people's blood vessels, and it will thoroughly clean blood vessels and waste on their walls.

As long as people regularly use the robot I invented to clean blood vessels, then his or her blood vessels can be unobstructed at all times.

Therefore, in the future, people will no longer have to stay away from their favorite foods such as braised pork because of cardiovascular and cerebrovascular diseases.

That's not all this robot can do. It can also reach every part of the human body and send back the image of that part that the doctor wants in real time. Is it much more convenient than the current X-ray machine? What's more commendable is that this robot can also clean up a lot of fat accumulated in the human body, and those women who love beauty no longer need to take diet pills or even fast in order to lose weight.

As long as I use the robot I invented, women who love beauty can always keep slim and eat whatever they want, and no longer have to worry about obesity caused by overnutrition! How's it going? Is the robot I want to invent capable? Are you excited? Come and find me!

What 600 words do I want to invent for primary school students' composition

What composition do I want to invent, son? You must also want to invent the magic pen.

Aren't we usually reluctant to do our homework? It will be useful.

It is wearing a dress that shines like a diamond and a small red flower on its head.

Don't underestimate that little flower. It has six petals. The six petals are printed with the handprints of the six relatives of the young master, and the middle bud is the handprints of the young master.

If someone steals it, it will call the police, and the thief's hand will be tightly glued until the owner catches the thief.

It can also help people do their homework. All you have to do is shout "magic pen, come and help me with my homework."

"Of course, it can also recognize the voices of the owner and six relatives, and thieves can't do without it.

Draw a horizontal line in the exercise book and think about it in your mind, and you can easily finish your homework.

It can draw anything like a magic pen.

You can use it to draw some pens as magical as it and throw them into the sky. It either flies to the disabled or to good people. If a disabled person or a kind-hearted person gives it to a person with a very vicious heart, what he or she draws is nothing.

Look, this is the magic pen I want to invent. Although it is only a fantasy, it will come true when I grow up. What composition do I want to invent? Ordinary umbrellas bought on the market now have only one function. Wouldn't it be more convenient if an umbrella had multiple functions? So I want to invent a multifunctional umbrella.

There are many small buttons in different colors on the umbrella.

At the top of the umbrella is a microcomputer powered by solar energy.

Let me introduce his function to you.

Press the yellow button to start the bat device. You can hold the handle of the umbrella, and the umbrella can take you soaring in the sky.

Don't stand under the umbrella when you press the blue button! Because at this time, it will rain cats and dogs under the umbrella

This umbrella can also be used for breakfast! You put an egg in the nth space, press the red button, and the egg will be cooked in less than one minute.

You are tired of studying. Press the green button and you will enter a virtual world, where you can play computer games.

This umbrella has many functions, so I won't introduce them one by one.

In the near future, with the progress of science, my invention will surely come true.

At that time, you can use it yourself! ...

I want to invent xxx500 words for my composition.

The garbage robot I want to invent is not the real garbage robot, but the "garbage" in "garbage"! Because it eats garbage, its stomach is full of garbage.

However, what it excretes is not necessarily garbage, so I'll tell you about it.

This garbage robot has a huge mouth, a copper body and an antenna on its head, which can be controlled by a remote control.

Its neck can be said to rotate 360 degrees, while its body is somewhat riddled with holes.

Because, every hole will extend a tool to clean the garbage on the ground.

Its feet can also be turned into pulleys and brackets.

This is the future environmental protection robot.

Usually, it will roll pulleys and patrol the city. The antenna on its head can sense where there is garbage, and the robot will go at once.

Sweep with a broom, or reach for it.

If something can't be swept away and sticks to the ground, wash it with water and scrape it off with sandpaper.

Especially in a big, dirty lake, he will use a net to pick up garbage like a fisherman.

Of course, its feet will become scaffolding, and then go into the water to check it again.

If the water is still turbid, it will open its mouth and suck hard, and all the lake water will be sucked in and all the clear water will be discharged.

Finally I farted, hehe, it smells good! What do you think of the robot I invented? You don't like cleanliness, buy one and go back to be a nanny! Last night, I had an incredible dream. The magic doctor is me. I made many things for people to use: I invented the shoes of the four seasons with four buttons on them. The first one is leather shoes in spring. On sunny days, I wear leather shoes and sing and dance with birds ... The second one is summer sandals. I put on sandals and it's not too hot to exercise in hot summer.

The third is autumn sneakers. I wear sports shoes. On a crisp autumn day, I don't have to worry about running and kicking shuttlecock.

The fourth is warm shoes in winter. I put on warm shoes so that my feet won't freeze.

One autumn, I dreamed that Xiaohong was going to take part in a running race, but today, she only wore leather shoes instead of sports shoes. What should she do? Seeing Xiaohong's anxious look, I lent her the shoes of Four Seasons. After Xiaohong put it on, I pressed the button of autumn shoes, and the shoes immediately became a pair of sneakers according to the size of Xiaohong's feet.

Xiaohong said in surprise, "Xiao Ting, you are great. You can find out how to make this high-tech thing.

"I listened to, satisfiedly smiled.

She put on this pair of suitable sports shoes and won the prize in the running competition! I also invented many things, such as: Happy Valley, singing flowers.

For ordinary people, ordinary people are very happy after using it, and they also praise me as a gadget! Just then, an alarm clock woke me up, and I said gloomily, "It was a dream! Makes me happy for nothing.

"However, I hope that one day, I can become an inventor. ...

What composition do I want to invent?

I want to invent a trendy bed _ Imagine Composition I am an inventor and invented a trendy bed.

This kind of bed is very soft, just like a normal bed, but the bed I made is amazing.

This bed can be massaged.

In the evening, people go to bed after work. If you can't sleep, press the yellow button, and the bed will send out a beautiful lullaby to make you fall asleep unconsciously.

At night, the streets are still bustling. If you press the green button, the bed will eliminate 100% noise and make you sleep comfortably and warmly.

If there are mosquitoes in your room, this bed will automatically give off fragrance and make people very comfortable. If mosquitoes smell this fragrance, they will die.

This bed will also automatically adjust the temperature. In summer, you will feel as cool as autumn, and in winter, you will feel as warm as spring.

This bed will make you feel comfortable; Let you sleep soundly; Tomorrow will be very energetic.

If people are tired when they come home from work, they lie on the bed, press the red button, and a pair of "hands" extend from both sides of the bed to massage and knock on the back.

"Ding, ding", the bell of the alarm clock woke me up.

I must study hard, make progress every day and invent something more magical than this.

I have always dreamed of becoming a scientist and inventing more, better and more convenient things for people to use.

My biggest dream is to invent a multifunctional house.

If you have a multifunctional house, it can not only save you money, but also take you away from all disasters.

Let me introduce its function to you.

If you invent a multifunctional house, you don't need to buy any furniture. You can choose your favorite furniture by pressing a key on the floor.

If you invent a multifunctional house, you don't have to worry about the temperature in spring, summer, autumn and winter and what clothes you want to wear.

Because as long as you say how many degrees you need, it can adjust how many degrees for you.

If you are hesitant about what to wear, don't worry, just face the wardrobe, which can be changed into the clothes that suit you best.

If you don't like the color of the house, no problem, just say what color you want, and the house will become your favorite color immediately.

If you don't like cleaning the house, no problem. As long as you say you need to clean your house, two arms will stick out from both sides of the wall to ensure that every corner will be spotless.

If there is an earthquake, don't worry, it will start flying skills, take you to heaven and stay away from disaster.

How's it going? Isn't this multifunctional house good? When I grow up, I will certainly invent many scientific and technological achievements to save mankind from disaster.

...
