First of all, it should have a beautiful appearance and rich colors. These shoes are light and durable, and can be used for decades. Its volume is exactly the same as that of ordinary shoes, but its function is different. The size of shoes can be adjusted according to the size of feet.
Secondly, the safety of shoes. The inner layer of safety shoes adopts new sponge, so water is not easy to penetrate into socks. When it rains, the rain seeps into the shoes, and the sponge will automatically suck the water together, and then discharge the water under the pressure of the feet, so that our socks won't get wet, and we don't have to worry about catching cold and getting sick. When crossing the road, it can sense the arrival of vehicles. When the vehicle is at a distance from us, the safety shoes will automatically stop, which can avoid traffic accidents.
Finally, wearing safety shoes can also drive freely on the sea, because a submarine-like device is installed on the shoes, which can drive on the water.
How about my safety shoes? In today's advanced science, I must study hard and realize my dream of safety shoes in the future!
What do I want to invent according to animals? I learned about the life characteristics and special abilities of woodpeckers and anteaters from the revelation of nature. From them, I suddenly thought of a problem and got an inspiration: in rural orchards, we often find pests drilling into tree trunks and mature fruits. In order to protect the fruit forest, farmers have to spray a lot of pesticides. What is the result? Not only is the cost high, but people eat it, and the pesticides that exceed the standard are scary. If pests are not killed in time, people have to cut down those "incurable" fruit trees.
In modern rural areas, it is impossible for so many woodpeckers to help fruit trees see a doctor.
Nature has given people a lot of inspiration. Planes were invented according to dragonflies, and streamlined boats were invented after whales at the bottom of the sea. So I'm thinking: why don't we make a portable pest control machine by imitating the mouth of woodpecker and the tongue of anteater? In this pest control machine, we can install a computer chip, so that it can accurately detect diseased trees. Then, we can press a red button on the handle, and a pointed hooked steel pipe similar to a woodpecker's mouth will pop out from it. It can accurately make a tiny hole in a tree with pests, and then hook it out with a hooked steel pipe mouth.
What about termites? Don't panic, we can put the steel pipe mouth in first, then press the green button, and an anteater-like tongue will pop out of it. As soon as the sticky long tongue "drills" into the hole, termites are easily and completely eliminated.
How beautiful nature is! I love nature!
My invention composition is 400 words. My invention "Today is June 65438+1October 1 1.
"My little robot reported.
Now I have become a famous scientist and invented many things, which are deeply loved by people.
At this moment, my assistant pushed the door in and said to me, "Urgent notice. A gangster took a hostage at the airport. Please get there at once. " .
""I'll go right away.
"I replied, taking out my recently invented tracker-tracking birds.
This is a kind of bird that catches bad people. It looks like a real bird, with golden feathers and a sharp mouth.
But it has extraordinary skills and can lift objects weighing 500 kilograms.
On its tail, there is a scanner. Just put the gangster's photo in it, and no matter where he goes, the bird will find him.
Then, contact the police through the alarm on its head.
I took the bird and my assistant aboard the airship and arrived at the airport.
"The gangster is coming.
"The policeman who greeted me pointed to a room and said to me.
I released the bird and took the photo in the hands of the police, but the bird did not move.
"Hey? Why don't you move? " I'm surprised.
I looked down at the bird. Oh, the switch is not on yet.
I stretched out my hand and pressed it on the bird's abdomen, only to hear a "squeak" and the bird flew away.
Write a composition (400 words) on the topic of "My Discovery" or "What I Want to Invent". An ordinary painting may not attract your attention.
However, there is a secret in an ordinary painting.
One day, my father bought a painting from other places.
My father said to me mysteriously, "Don't touch this painting, is it magic?" So, dad put the photo in the study.
I asked my father, "What's so magical about a broken painting?" Dad said, "Haha, you don't know that!" " Because the color of this painting is different during the day and at night.
"The same painting, the color of the day and night is different, how is that possible? Filled with curiosity, I decided to watch it again at night.
In the evening, I sneaked into the study while my father was not looking.
The result was beyond my expectation.
This picture is still bright during the day, but how did it turn dark yellow at night? Did you use any special pigments? I shouted so loudly that my father heard me. Father rushed over and boasted, "Look, it's amazing!" ! All right, get out! "I looked at this magical behind-the-scenes and thought hard about the reasons here, but I still couldn't figure it out.
So I went to check the information.
An hour later, my efforts finally paid off.
It turns out that this is all about the electric light.
Because the color of an opaque thing is determined by the color of the light it reflects.
It is bright during the day because blue light is reflected by its body.
The reason why it is dark yellow at night is that the most light in the electric lamp is red light and orange light, and the blue light and purple light are pitiful.
This is the reason why a painting has different colors day and night.
I was flattered to find the reason why the color of a painting is different during the day and at night.
At the same time, I also know that an ordinary painting contains so much knowledge, so how much knowledge in nature is waiting for us to discover! So pay attention to observation and learn more about nature.
I wrote 400 words in my invention composition. I finished my homework early yesterday afternoon.
There is nothing to do. I see a pile of cans in the corner.
I think: If those cans are dumped, it will pollute the environment. It is better to use them, which will not pollute the environment and can be used as waste.
This is the best of both worlds. "
So, I hurried to hold the cans and found all the materials for making small productions.
There are scissors, scotch tape, colored paper, cardboard and glue, and wool.
First, I cut a piece of paper with the same length on the colored paper according to the cans with small scissors.
Then stick strips around the cans and dress him in beautiful "new clothes".
Then cut four squares on the colored paper with scissors.
Stick squares on both sides of cans to make train windows.
Use scissors to make a small hole in the lower right corner and the lower left corner, and use wool to pass through the two holes.
Then cut four round wheels for the train with scissors.
At this time, I accidentally cut my finger and was still bleeding. "Oh, it hurts! I shouted.
I pushed the things next to me to the ground and wiped the blood on my hands with paper.
The person in charge looked at the materials that had fallen to the ground.
Suddenly I remembered what the old market said to us: "Don't give up halfway, just stick to it and you will succeed." .
"I sat on a stool and rang for a while. I suddenly stood up, picked up things on the ground and continued to be my little train.
I made five cars in the same way and connected all the soup doors with wool.
In this way, my little train is finished.
I hurried to my mother's room with the baby in my arms.
I said, "Mom, look at the little train I took.
"Mom looked at it and smiled sweetly.
I will make more small productions in the future, which can not only improve my hands-on ability, but also make use of waste. I'm really happy.
Today, I understand from this matter that you will succeed if you stick to it and are not afraid of difficulties.
Explanatory text, I want to invent something 400 words, I am a whimsical girl.
I often sit quietly alone, and my thoughts have already flown to that distant place.
How I want to invent a switch with four buttons on it.
Press the green button, the room will suddenly become beautiful in spring, and the young leaves of willow will wave to you, allowing you to enjoy the spring bath.
Press the red button, the room will become hot and sunny immediately, and there are trees everywhere. You will run over, take off your coat and have a comfortable rest.
Press the yellow button and the forest disappears, followed by a cool autumn wind.
The branches are covered with full fruits. You must be impatient. You want to try one right away.
Press the white button again, and the house is full of beautiful snowflakes. Even your body is covered with branches and snowflakes on the path.
At this time, you are crazy.
Snowball fights and snowmen are your first choice for playing.
How I want to invent an automatic working machine.
Silver coat, with a scary "maw", will think it is a real person if you don't look carefully! Just put the homework in its "maw" and then put the paper with your own handwriting in it, and the machine will start working.
As long as it takes ten minutes, the homework can be completed immediately, easily and with high quality.
With it, hehe, homework is not a problem! I also want to invent ... although this is just a fantasy, I will continue to work hard in this direction.
What composition do I want to invent? The schoolbag of the future is a multifunctional schoolbag. When you are at school or after school, if you are tired from walking, just press the green button and it will reach out and set a wheel. When you sit on it, it will drive to the door like a car.
If you are tired, just press the yellow button and you can spread your wings and fly to your door automatically.
The second function is to prevent heat. If you feel hot in summer, press the blue button and the bag will be covered with a protective cover, and there will be a cold air inside.
So it won't be hot in summer.
The third function is to prevent colds.
If you feel cold in winter, press the red button, and the schoolbag will also be covered with a protective cover. There will be heat flow inside, so that you are not afraid of cold in winter.
Ding, the alarm clock rang, alas! So this is a dream.
The future schoolbag Every student in Zhang Yu, Class Two, Class Five, LAM Raymond Primary School, Putian City, Fujian Province has a schoolbag. The style and color of the schoolbag are dazzling.
But with the growth of age, I know more and more knowledge, and I change more and more schoolbags, which are heavier and heavier.
We are not tall.
It suddenly occurred to me: will there be new types of books? First of all, the manufacturer stores a variety of styles and shapes in the schoolbag, such as: fruit shape, cartoon head shape ... If the young master wants to choose his favorite style, just press the red button at the top of the schoolbag.
Secondly, its shell is made of rubber and has the function of automatic contraction. The two buttons on the left side of the schoolbag are used to change the size, one is bigger and the other is smaller.
The textbooks and learning tools in the schoolbag will also change with the size of the schoolbag.
Then you can go to school with a small bag on your back.
There is also a transparent place in front of the schoolbag for loading the curriculum.
As long as you put the schedule in, when there is no textbook to recite, you will send out a "beep" alarm to remind the young master! Oh, great! Its switch is also different, unlike the current zipper, which can be broken by pulling hard.
Instead, it is a small button that can be turned on at the touch of a button.
Want to know what is the white button on the right side of the schoolbag? To tell the truth, it is used to enjoy music. As long as you touch it, it will immediately make a wonderful song.
When you are tired and bored, you can use it to relieve boredom.
How's it going? Isn't the new schoolbag nice? Not only beautiful appearance, diverse functions, but also very practical! Students, I believe this is by no means a daydream.
As we grow up day by day, with the continuous development of science and technology, in the near future, new schoolbags will be born in the future!
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 do you want to invent from animals? Nature is the teacher of human beings, for example, people observe thatch and invent saws, for example, people observe birds and invent airplanes.
I saw a gecko once.
One day, I went to the Pearl Park to play, and my good friend and I were in a good mood. I wanted him to see the "rain of leaves", so I reached out to the fence covered with vines and "wow" picked many leaves. I was just about to open a "split flower" when I suddenly found something soft and brown in the leaves. I thought: it won't be the kind that bites people, and it will also seal my throat with blood. But my curiosity drove me to catch the little thing with both hands, and a big stone fell to the ground at a glance.
I heard that the gecko's tail will grow when it is broken, so I took it home, cut it in half with a knife, put it in a beautiful moon cake box and fed it some water. When I looked at its cut tail, I found it was still moving.
I hurried to see the gecko. I saw gecko crawling on the wall! I grabbed it and two questions flashed through my mind. 1. Why does the gecko move when it is broken? 2. Why can the gecko climb the wall? Later, I checked the encyclopedia, only to know that the gecko's broken tail can still beat with nerves.
3. The fingers and toes on the four corners of the gecko are flat and wide.
There are skin folds under the toes and fine glandular hairs on them, so they have strong adhesion and can crawl on walls and ceilings.
I want to use the special ability of gecko to walk on walls and ceilings to invent something-gecko foot crawler: now some explorers go to some mountainous areas with steep mountain roads. If they are not careful, they will fall down and get seriously injured. Put on the gecko foot crawler, the explorer can walk up the mountain like walking on the flat ground.
I hope this gecko climber can be made with the development of science and technology.
Nature is like a kaleidoscope. As long as you can observe every plant carefully, every animal will make new discoveries.
I want to invent shoes. There are many kinds of shoes nowadays, but when people walk, they often feel some deficiencies. For example, shoes get sick when they are wet, and pinch their feet when they are young ... So, I fantasize about inventing a pair of multifunctional safety shoes one day. Do you want to know what they are like? First of all, it should have a beautiful appearance and rich colors.
These shoes are light and durable, and can be used for decades. Its volume is exactly the same as that of ordinary shoes, but its function is different. The size of shoes can be adjusted according to the size of feet.
Secondly, the safety of shoes.
The inner layer of safety shoes adopts new sponge, so water is not easy to penetrate into socks.
When it rains, the rain seeps into the shoes, and the sponge will automatically suck the water together, and then discharge the water under the pressure of the feet, so that our socks won't get wet, and we don't have to worry about catching cold and getting sick. When crossing the road, it can sense the arrival of vehicles. When the vehicle is at a distance from us, the safety shoes will automatically stop, which can avoid traffic accidents.
Finally, wearing safety shoes can also drive freely on the sea, because a submarine-like device is installed on the shoes, which can drive on the water.
How about my safety shoes?
In today's advanced science, I must study hard and realize my dream of safety shoes in the future! ...
I want to invent a universal pen, which is my dream and my ideal.
Points, points and points are the lifeblood of students.
If you fail in the exam, then I believe that the students will * * * "blossom" when they get home.
I invented this universal pen, which can save students from pain.
During the exam, you only need to scan the questions with the built-in scanner, hehe, and then the micro LCD can be calculated and considered by the internal microcomputer for thousands of times, and finally the answers are displayed on it.
Students, help yourself. It's a high-tech product that adults can't see.
) Wow, how convenient! After the exam, students can "go home with full load"! To say that this is a universal pen, its functions are not limited to these.
Take biology as an example, a magnifying glass can be extended from one end.
This magnifying glass can't be bought casually in the night market stalls. There is a cell microanalyzer on the upper left and a microanalyzer on the lower right, but it is specially used to observe bacteria, so it is called a bacteria observer. With this magnifying glass (or microscope), you can sit back and relax in biology class! At the middle end of the universal pen (that is, a little above the pen grip), there is a microcomputer nerve center receiver. As long as you can input the correct information, he can change it as he wants.
Let's show you. As long as you say "get up at 6: 30 tomorrow morning" to him before going to bed at night, then at that time the next day, even if you go to the north and south of the river, hide in the ends of the earth, as far away as South Korea, and as far away as South Africa, even if you leave it at home, it can use the thought induction system to wake you up accurately.
How's it going? Awesome! The universal pen is omnipotent, this one can do it, and that one can do it. It is really a good helper for human beings.
The universal pen is just an idea of mine, but I think it should not be too difficult to invent it in the near future after I have learned my knowledge and culture well.
So I want to take the universal pen as my life goal and move towards this goal.
