My invention, excellent composition

In study, work and even life, everyone must have been exposed to composition, which is a narrative method to express a theme through words. What is the composition you have seen? The following is an excellent composition I invented, which I compiled for your reference only. I hope it will help you.

I invented the excellent composition 1 ideal, what a beautiful word, it is like a compass, guiding me to success; It is like a ladder, helping me to climb the peak bravely; It is like a pair of wings, so that I can fly freely in the blue sky; Everyone has his own ideal, so do I, that is to be an inventor.

Nowadays, due to people's over-exploitation of natural resources, resources in our world are on the verge of exhaustion, such as forest resources and fresh water resources. The forest area of the earth once reached 7.6 billion hectares, but now it is less than 3.6 billion hectares. At present, about 60% of the world's areas are short of water, and about 654.38+0.5 billion people in 80 countries around the world are short of water, among which about 300 million people in 26 countries live in a state of water shortage. Many resources in our world will soon be consumed by people. Therefore, I want to be an inventor. I want to be a cloning machine, cloning many non-renewable resources, so that all kinds of resources on our planet are very rich. You can also clone some endangered animals to make their families grow and develop.

Now, the air around us is no longer fresh. Because there are many large factories in our motherland, the current air pollution situation in our country is very serious, mainly manifested in soot pollution. These pollutants mainly enter the human body through the respiratory tract, and are directly transported to the whole body through the blood without being detoxified by the liver, which is extremely harmful to our health. So I also want to make an "air freshener", which can absorb pollutants in the atmosphere. After special treatment, those polluted air will become fresh air and be discharged in a short time. With this "magic weapon", the air around us will definitely give off a faint fragrance of flowers.

Trust me. Twenty years later, I have invented many things and am a great inventor.

In the summer vacation, when I finished my homework, I called my friend Lei Jiayin to chat. However, this call lasted for two or three hours and wasted a lot of phone bills. Mom was furious when she knew: "You are not allowed to call Lei Jiayin in the future, and you are not allowed to chat online." . I muttered discontentedly, "If you don't talk, you won't talk. When I learn English at Harvard and get the first place, the computer will be mine. " "That won't do either!" Cried the mother. "Then I'll make my own mobile phone!" "If you have the ability, you can build it!" Mom said contemptuously.

Go ahead. It's hard to say. Well, I went into the refrigerator, huh? Where are the paper cups in the refrigerator? I turned left and right, but I couldn't find it. Did it fly into the sky with wings? Or are you stuck in the swamp and going to hell? Even if it runs away with long legs, there is no paper cup anyway, so it can't beat me. I have 10 yuan's "private money". I used this 10 yuan to buy a pack of paper cups, which can be used not only to make phone calls, but also to hold water for guests at home. It's killing two birds with one stone. I prepared two paper cups, dug out a ball of wool from my mother's closet, punched two holes in them, and connected them with wool, one at Lei Jiayin's house and the other at my house. If Lei Jiayin wants to talk, pluck his hair and cover his mouth with a paper cup. When I aim my ear at the paper cup, I can hear it, which not only saves electricity, but also can hear the other person talking. This is killing two birds with one stone.

I am very happy to think that I am so smart and will become a scientist after a long time. Then mom came up and said, "You are great!" So I said modestly, "just so-so, the third in the world!" " At this time, Lei Jiayin also came from there: "I also came to share your phone with you." .

If I were an inventor, I would invent a crutch that can help the elderly. I named it "the universal stick". The old man is inconvenient to move. If he falls down carelessly, his bones may be broken. Therefore, I want to invent the "universal stick", hoping to benefit the elderly.

The universal walking stick looks like an ordinary walking stick. There is a small hole at the top of the cane. As soon as the chip in the hole is received at the command, the cane will obey the command. Out of concern for the elderly who can't talk, there are two kinds of universal sticks, one is "smart stick"; One is the "hidden energy rod". The hidden energy rod has many advantages. If gangsters kidnap an old man, the old man can make the hidden energy bar invisible, give orders in his head, and the hidden energy bar can call the police. The intelligent staff does not have the function of "giving orders without talking", but the invisible can see the intelligent staff, which is more convenient for the visually impaired. The wand also has a special help-seeking function. If a fire breaks out suddenly, it can be turned into a wet towel immediately, so that people will not suffocate.

The universal wand has many functions. I hope the elderly can feel its convenience. In fact, I want to invent the universal wand because of my elderly grandmother, because I don't want to go to the remedial class after school and take care of me. Grandma is old, unable to move, and her eyesight is declining. For her sake, I resolutely decided to invent the "universal wand", hoping that grandma would be safer and have a good old age.

Today, one year later, I stand on the podium and accept the award from the Association for the Aged. The invention of the universal wand swept the world. ...

My Invention Excellent Composition 4 Future Cars In the next 20xx years, I will invent a car. Let me introduce you!

Because the energy on the earth is limited, using gasoline will pollute the environment, so my car uses electricity. When the weather is clear and sunny, the car will automatically stretch out the solar panel to absorb solar energy and convert it into electric energy. The inexhaustible electricity can be automatically stored and used when there is no sun.

The facilities in the car are also complete, including living room, bedroom, kitchen, dining room, bathroom, color TV, refrigerator, videophone and so on.

Another function of my car is that it can travel in water, land and air. If you want to explore the bottom of the sea, press the red button and the car will be painted all over and turned into a submarine. If you want it to fly in the air, press the green button, and the car will unfold its hidden folding wings and become an airplane.

Open the back of the car and three hands will come out. The first hand will automatically clean the car when parking, the second hand can turn the car into a trunk according to the needs of the owner, and the third hand can automatically change the tires.

Look, this is my dream super invincible car, not bad! In order to realize my dream, I will study hard and master more scientific knowledge.

My Invention Excellent Composition 5 Students, have you ever had such an experience: as soon as you come home from school, you will be busy with your homework until eleven or twelve in the evening. Especially in exams, time is tighter and people are more tired. But with this machine, everything will change.

My machine can change its size at will, from a house to a speck of dust. You can wear it on your hand. It is shaped like a watch and can tell the time. People who don't know think it is a real watch. But there are two buttons on the left and right sides of the screen to see the time. One is red and the other is green. The red one is the tray for homework. As long as you put your homework in, the time screen will stop working. At this time, you just need to look at the screen and think about the answers to your homework in your head, and this machine will write what you think into your homework. Quite time-saving. Some people will ask, what should you do if you think the wrong answer? Don't worry. When you enter what you think, your answers will be printed in pencil.

This machine will remind you whether it needs to be replaced. If so, you have to choose the multiple-choice question number and then change the answer. The green button will help you check after you change your answer. Check the mistakes and remind you to correct them.

After talking for a long time, maybe you will ask, what is the name of this machine? I'll tell you it's called-"children eat lollipops"!

Inventors can invent many things for mankind. I want to be an inventor, inventing all kinds of shoes for mankind and bringing convenience to mankind.

The actors put on my music shoes, and as soon as they step on them, the shoes make a wonderful music sound. Look at them singing and dancing on the stage. Their songs are so sweet and their dances are so beautiful. The following audience cheered for them, cheered for a while, and wondered again: hey! I don't see a band. Where does music accompaniment come from? Oh, it turns out that the little actors' musical shoes are accompanying them. It's really interesting.

People who travel put on my speed-changing shoes. The speed-changing shoes have a small remote control to control the speed and change the direction. At a scenic spot, you can enjoy it here by pressing the slow key, and then you can reach another scenic spot in a blink of an eye by pressing the fast key. It's convenient and fast to travel in it, and I'm really happy.

In the evening, my uncle and aunt who are on the night shift walk on the road and put on my night shoes. There is a light bulb at the toe of this pair of shoes. As long as the switch is turned on, the light bulb will glow to avoid falling into the puddle or tripping. It is really convenient.

Everyone put on my temperature-regulating shoes, which are cooler than sandals in summer and warmer than cotton shoes in winter ... Spring and autumn are neither too hot nor too cold, which is really comfortable.

I want to be an inventor, because I want to improve the living standard of human beings. So, from now on, I will study hard. I believe as long as I work hard, I will succeed.

My Invention Excellent Composition 7 If you were asked to invent something, what would you invent? I will invent a time machine that can shuttle back and forth-a time machine.

I invented the time machine because I wanted to make up for my previous mistakes. For example, I once disappointed my teacher by stealing answers to papers, and I once stole my mother's money to buy some unimportant things, all kinds of mistakes. I believe that as long as there is a time machine, everyone can correct their mistakes.

In addition, I want to go back to the Three Kingdoms period at the end of the Eastern Han Dynasty and see the heroes who fought each other and died for their country during the Three Kingdoms period. At the same time, I also want to comfort those parents who lost their loved ones because of fighting. I also went back to the Qin Dynasty to watch the establishment of the Great Wall in Wan Li and how the violent rule of Qin Shihuang and Ying Zheng made people miserable to satisfy my curiosity. And go to Egypt to enjoy the construction of another wonderful and mysterious pyramid. Of course, experience more things? Because surprises and things I have never experienced are also indispensable.

Then, I will make a setting for the time machine, which is set to only do good things and not do bad things. Because I am afraid that some lawless elements will use it to change the frozen history and realize their ambition to rule the world. At that time, there was sadness everywhere and people in pain everywhere. I invented the time opportunity to become the number one criminal. It was me who was sad at that time, because I gave him life in the time machine. Instead of making the time machine the number one criminal, let it become a kind machine to help others. Because it is up to me to decide whether it is good or bad.

Finally, before I die, I will take the time machine I invented to relive the bits and pieces of life, such as joys and sorrows, like a dead lamp. Then, I will die without regret.

I think as long as people make unremitting efforts, the time machine will be invented in the near future.

Everyone has a wish, and I am no exception. My wish is like countless twinkling stars in the sky. Among them, my greatest wish is to be an inventor.

When I was seven years old, my parents often took me to the Science and Technology Museum. Every time I go there, it opens my eyes. There are robots, universal cars and airplane models that help people do housework. ......

One night, I had a dream that I really became a great inventor and I invented a bus. There are three floors. The first floor is where passengers sit. There are three special buttons on the passenger-made seat, which are red, yellow and blue. Red can make you eat delicious food, and yellow can indicate your specific location. It is convenient to get off at any time, so you don't have to worry about standing or getting lost. Blue can provide you with water or drink. If you press it three times, a toilet will appear. The second floor can be called an energy storage bin, because this kind of bus runs by solar energy instead of burning gasoline. The third floor is special, with a tube that absorbs toxic gas and many shower heads, which can help Mother Earth change clothes. This kind of bus can be folded, which is convenient for traveling and can also be turned into various cars.

Although this is only a dream, I believe it will come true in the future. I will study hard from now on and make progress every day. I believe we can invent more interesting, convenient and advanced things in the future. Let's wait and see.

My invention is great. Now robots are very powerful. They can do things that humans can't. They can go deep into the disaster area, relieve the crisis, go deep into the human body to check the condition and treat the disease. Hey, my robot is Yinhe 9 diving robot. I organized a "Peach Blossom Garden Ten Boundaries" in our class. I'm Laojiu, so I'm Yinhe No.9, and others can get up at will, but it must be based on who you are. My robot specializes in saving people or searching for treasure at sea.

As we all know, it is very difficult for us scientists for robots to "strike" without electricity. Everyone thinks that the battery can be used, but the battery will soon be dead and the robot will sink. Then, wouldn't it be a vain condensation of the efforts of the uncle who made this robot? It is assembled bit by bit, just like a complicated puzzle. The uncles who are robots have been electrocuted many times because of their failure. It is impossible to put wires into the water to transmit electricity! That will shock the swimmers. Hey, hey, I have an idea that there will be oxygen ions in the water and electricity will be generated. Just install a water inlet and a machine that can convert oxygen ions in water into electric energy in the robot. Haha, in this way, when there is no electricity, just open the water inlet and the water will be decomposed into electricity by the machine as soon as it comes in. So my Yinhe 9 diving robot will always be fully charged. Don't worry about the power!

My invention excellent composition 10 Now we travel far and spend a lot of money on air tickets, but I have built a high-tech product-the seven-star ladybug car. There are seven spots on its body, which are red spots, orange spots, yellow spots, green spots, green spots, blue spots and purple spots. They are oval. Next, I will introduce its functions to you!

The shell of this seven-star ladybug car is very hard and made of Titan iron. Whether it is floods, mudslides or typhoons, it can be well resisted and the people inside will not be affected.

When encountering traffic jams or red lights, it can spread its wings and fly in the sky. If you press the orange dot again, it will immediately fold its wings and land on the ground. This saves a lot of time for our trip and greatly improves the efficiency.

This car has no steering wheel and brake button, and it is pure artificial intelligence. We don't need to take a driver's license. We just need to tell us where we want to go. When you meet a turning road on the road, you just need to say "turn" and the car will turn. If you say "accelerate", the car will accelerate. Is it convenient?

At this time, others will ask: What are the functions of the remaining five points? In fact, the yellow dot makes the car bigger, and the green dot makes the car smaller, so that if the aisle is narrow, you can easily pass; If you feel too hot, just press the green dot and shout "2 1 degree", and the temperature inside the car will drop to 2 1 degree immediately; If there is smog, just press the blue dot, it is a "super invincible powerful fan", and the smog will be blown away immediately. Purple has the most special function. It can be an intelligent robot. I can chat with you when I am bored. Tell you some funny jokes when you are angry; I can give it to you when you are tired.

Do you like the ladybug I invented?

My excellent invention composition 1 1 My family has a particularly practical food robot.

"I want a glass of milk!" Dad put down his schoolbag and lay lazily on the sofa. "The owner of the cow will arrive in a minute." The robot writes on the micro menu while preparing fresh milk. "coming, master!" The robot said, "What else!" "Have a coke, Fanta, mineral water, chicken wings, chicken legs, hamburgers, pasta …" Dad screamed, "Yes, there are delicious desserts, sandwich cakes, chocolate biscuits, strawberry-flavored spherical chocolates …" "It will appear soon." I don't know where the robot went, only that its echo echoed in the hall.

After a while, I only heard the sound of "tinkling" in the kitchen. Several arms of the robot kept shaking, some with knives, some with shovels and some squeezing juice. I saw the ingredients flying in the air, and in a short time, all the ingredients were neatly arranged. Robots put these ingredients in different pots, and the food is ready in a blink of an eye.

After 30 minutes, "dong" and "all the food appeared." The robot took off its hat and all the food appeared on the hat table. Dad wolfed down and gave a "cough". Dad burped with satisfaction. "I'm going to bed!" "Finally, a glass of water and a cup of mint." Dad stretched himself and said softly. "Right away, sir!" "Sir, these ingredients are gone. Do you need some of these ingredients? " The robot saluted and continued, "You only need one yuan to get clean water. This kind of sugar is more expensive." "That doesn't require a reservation!" Dad said.

My robot is cool!

My invention excellent composition 12 We started to use pens this semester, and I was in a lot of trouble. The pen won't run out and leak when writing, and the pencil is easy to break, so the words written on it will fall off as soon as it is wiped, so I thought: Can you invent a special device to check if there is anything wrong with the pen? I thought about it and came up with something-a pen tester.

The pen tester is a small ring that can be enlarged and reduced. It can be put behind a pencil and a pen, and there are four different colors of small lights on it: red, yellow, blue and green.

When the pen has not run out of water, just look at the pen tester on the back of the pen. If the red light is on, the pen is out of ink. If the yellow light is on, your pen is not smooth. Just wait three seconds, and the pen can write. If you are afraid of filling too much water when adding water, just look at the green light, which means that the pen is full and you don't have to worry about leaking it. When using a pencil, it breaks easily. Put the pen tester in the back and hear the sound of "drip, drip, drip", which means your pen is going to break. Wait ten seconds, the pen won't break. When you write a line with a pen, your hand may erase the words, there is ink on your hand, and the words on the book are also erased. Put the pen tester straight and put it on that line, so that the pen tester won't erase the words and the hand won't touch the ink.

I really hope that when I grow up, I can be an inventor and invent this pen tester.

My invention excellent composition 13 This morning, I did my homework at home and made some mistakes. I picked up the eraser and wiped it, leaving a lot of dirty things on my homework immediately. What should I do with these crumbs? So I thought of inventing a little invention to deal with rubber crumbs.

But what kind of things should be made to deal with these debris? I thought and thought at my desk, but I still couldn't remember. I paced back and forth in the room, thinking about this problem. At this moment, I saw a broom and dustpan in the corner. They can clean things on the ground, and I can make a "clean eraser" like them.

How? I've been thinking about it, and suddenly, I had a brainwave and came up with a good idea. My idea is to add a broken brush to one end of the eraser, so that there will be no rubber crumbs after wiping with the brush.

Production has begun. I first dug a hole at one end of the rubber, neither deep nor shallow. Next, put the brush in the hole and stick it with glue. If you are still afraid of cracks in the eraser, glue it with transparent glue for several times, so that you can make a small, convenient and practical clean eraser. Dry it and you can "put it into use"

A clean eraser can erase type without leaving rubber foam. This is killing two birds with one stone.

How's it going? Is the clean eraser I invented not good? It seems that as long as we are willing to use our brains and be brave in practice, each of us will create something.

My invention excellent composition 14 I tasted the joy of creation. Have you ever made a gizmo? If so, you must have experienced the feeling of success. I'm happy and excited, right? You didn't? Please experience it. I once made a small production, which was a periscope. This periscope, which I made after the submarine periscope on TV, takes a lot of effort. First, take a long water pipe, grind both ends from coarse to fine, bend the slightly thicker water pipe at 90 degrees on the previous one, then connect the other end with the previous one, and then put the slightly thicker water pipe on one end. Looking at a thick section, such a rough "Z" shape came out. Sticking the lens is the most difficult step in the whole process. I stuck it several times, and I almost wanted to get rid of it several times, but then I thought: how can I give up halfway if I want to make it to the end? So, I did it again, and later I found out the reason why it didn't stick well. Because it only had four sides stuck on the side, and the strength was too small, I made a triangular wood block as big as one side of the lens, which made me stick the lens smoothly. I dipped one end into the water and observed the other end. What's going on here? Just water. I obviously put some water polo in it. I took out my periscope and found that I forgot to pack sodium silicate. After I install it, I can see clearly what is underwater. At this time, an indescribable joy welled up in my heart, and I jumped three feet high with joy. This small production made me realize that the process of childbirth is hard, but the result will make you very happy and excited. I tasted the joy of creation. ...
