If I am a scientist, 20 years later, if I am lucky enough to be a scientist, I will invent many things that are beneficial to Mother Earth.
First of all, I want to invent a "tree that purifies the environment". This tree is different from other trees. Its seeds will grow as soon as they touch the soil, and they will grow into towering trees and become useful materials within one day. And it will breed in five days, and in less than five days, a large desert will immediately become an oasis. There are many varieties of this tree, such as ornamental trees, fruit trees and furniture trees ... This tree will not be eroded by insects, but will reproduce more or less according to the requirements of its owner, purifying carbon dioxide in the air and all gases harmful to human body.
In fact, I will also invent some animals to protect the environment. There is a kind of bird that lives exclusively on toxic substances in the air. It sucks toxic gas into its body, and then purifies it into oxygen, which is discharged from the small holes in its feathers. There is also a kind of fish that eats garbage. It will eat up the garbage in the water, and then spit out some small animals such as carp and shrimp, which is beneficial to the ecology. There is also a kind of kitten, which will eat all the garbage on the land and then discharge the seeds of grass. It will live with harmful gases and make the world a better place.
Thirdly, I also want to invent a tripartite means of transportation by land, sea and air. It will become an airplane, which will lead us to soar in the sky and visit the sun, moon, stars and other celestial bodies in the universe. This ship will also deliver oxygen to the cabin at any time, which is more convenient for us to visit. On land, it will change into off-road vehicles, armored vehicles, tanks and other vehicles, and will also lead us to visit the Grand Canyon in East Africa, Hawaii and other scenic spots. In the sea or lake, it will become a submarine, leading us to see all kinds of fish and coral reefs and enjoy the wonderful scenery of the sea.
Besides, I will. ...
If I were a scientist, I would invent something to change history and make the tragedies in history change.
In 20xx, I invented the time machine, which uses the gap in the universe to expand and turn back time, from a few minutes and hours to tens of thousands of years, and can travel freely. For example, we can use a time machine to transport atomic bombs and other nuclear weapons to protect the Summer Palace, defeat the surrounding British and French allied forces, and protect our Chinese treasures, so that China will not spend thousands of dollars on the cultural relics of the Summer Palace, and China will be able to add a unique garden and garden; A "national treasure"
If you can set the time machine to 65,000 years ago, and you can see the calm and heroic appearance of dinosaurs and how they became extinct, then I can solve this eternal mystery.
If I move the time machine to 600 years ago, I can see the miracle of the empty China Garden in Babylon, Cuba, and you can see the construction process, shape and appearance of the garden. I think this activity will make everyone ecstatic.
In 20xx, my second scientific research achievement was also successfully developed. It's called the gene bank. It can store all the genes for thousands of years. When the gene is lost, we can adjust the gene and culture it in the laboratory for a few days. The lost gene can be restored to its original form.
What if the reserve is full? We put it in a "compact box", a compact box with one trillion genes. The reserve bank usually has dozens of such boxes, so only one in the world is enough.
Although this is my dream, as long as I study hard, my dream of becoming a scientist will definitely come true in the future.
If I were a scientist, I would invent a beautiful multifunctional dress with six buttons.
The first button is used to adjust the thickness of clothes. People who are afraid of the cold will become a thick fur coat by pressing this button gently in winter. People who are afraid of heat in summer will become short-sleeved vests as long as they gently press this button.
The second button is used to turn into a vehicle at will. For example, if I want to fly from Nanjing to Beijing, just press this button gently and a pair of white wings will immediately appear on the back of my clothes. Just flap your wings gently, and you will fly very fast, and you can get where you want to go in less than a minute.
The third button is used for health care and beauty. As long as you press the button, I will give you a massage every day, which can not only play a role in slimming, but also be used for beauty.
The fourth button is used to adjust the color of clothes. No matter where you are, no matter where you are, you can change into your favorite color, and colorful stripes will appear on it, which will definitely make you more beautiful.
The fifth button is used to adjust the size and shape of clothes, but this button is special in that it will automatically adjust the size of clothes, so you don't have to worry.
The last button is used to wash clothes, which is much faster than our washing machine. As long as you press it with your hand, the dust on your clothes will automatically fall off. There are still two pockets on the clothes. What you want, you will have in your pocket.
Unfortunately, I am too young to be a scientist. If I grow up to be a scientist, I will certainly develop such clothes for the benefit of mankind!
In this colorful world, countless people are devoted to science. Madame Curie won two Nobel Prizes. Mao Yisheng built the Qiantang River Bridge; There is a world-famous rocket expert Qian Xuesen ... The story of these legends is that I like the post of scientist. If I am a scientist, I am dreaming.
If I were a scientist, I would invent a nutrition machine. In modern society, obesity has attracted many people's attention, because it has become the chief culprit in inducing various social diseases. So the first function of this nutrition machine is to lose weight. There are three buttons and a chair on this machine. Press the first button to sit in the chair, enter the weight after losing weight, and then sit on it for a few minutes, and you will lose weight successfully. Its second function is to tell us what nutrients the body needs. When you feel exhausted, sit on it and press the second button. The vitamin or calcium you need will appear on the display screen, and C will help you adjust your diet and schedule until your nutrition is restored.
One of his most popular functions is that he can help us solve common diseases. When you have a fever or a cold, he will tell you by voice and send you medicine through the manual system. I hope these are not fantasies. I want to be a great scientist who has devoted his life to the motherland.
If I am a scientist, then I will become an environmental scientist.
The ancients said: If you don't sweep a house, how can you sweep the world? Then my scientific age must start at home. First of all, I make a dirty water converter, which can do some treatment before the dirty water is discharged, so that the dirty water can be converted into pure water. Of course, it saves electricity.
Then I will make a multifunctional stool, not made of wood. But the garbage in our lives. After some processing, it has special functions. For example, if you sit on it and fasten your seat belt, as long as you point out where you want to go on the map provided by it, it will leave immediately and fly to your designated place. If you are hungry on the road, it can also take food out of the storage box! So you can eat and fly.
Brushing your teeth is what everyone must do after getting up in the morning. You often pour a glass of water to brush your teeth, but you don't need it. You have to dump it, so you will waste more and more water over time. In this way, I will make a toothbrush. There is a small mouth and a cover at the top for filling water. Click on the small hole next to it, it will cooperate with you to spray water, and it can be used next time.
After I finish my task at home, I will turn my attention to society. Replace the hard shell of the car with a fragrant and soft pie, but the oil added to the car is fruit, so the car will not smoke. In this way, when the food and water are finished, you can eat the car. Someone will ask how to get there after the car. Don't worry, because there is a dough maker on the edge of its chassis, it has the function of regeneration. When the old one is finished, a new one is created. You can still drive.
This is my wish as a future scientist.
If I become a great scientist, I will spend my whole life thinking about scientific problems. Scientists are an extraordinary profession. Scientists like Einstein, Galileo and Newton have great influence on science. I admire lecturers very much, so I want to be a scientist. I grow up day by day and learn more knowledge day by day. I know the music "Emperor Taizong, Liu Bei, Kangxi ..."
These great people, this is a lot I have learned as a man. Success is composed of hard work, persistence and talent, so I have created such a formula: realizing dreams = hard work+persistence+talent. If a person realizes his dream, if there are some bumps along the way, don't give up and keep on insisting. There is a saying that "persistence is victory". I once imagined obsessively: "Will there be life on Mars? Could it be ... "I really want to solve this mystery, so I really want to take an astronomer to discover another home of mankind and solve the mystery of the universe.
Of course, I know it is not easy to be a scientist. You must have a strong thirst for knowledge and imagination, and you must have the spirit of not being afraid of difficulties and failure. But I believe, "As long as there is perseverance, the iron pestle is ground into a needle." If you can't catch the spring water, you can't finish your study. I have the confidence to break through all difficulties and pursue my dream.
If I were a scientist, I had an ideal of becoming a scientist since I was a child.
When I was a child, I often heard my grandmother complain: "What's the use of scientists? It is difficult for me to choose vegetables unless I invent something useful. If only I had invented the vegetable picker! " If I were a scientist, I would help people solve this problem and invent a vegetable picker. Remove all the leaves of the vegetables to be sold, and when you buy them back, people won't worry about picking vegetables.
In the fourth grade, correction tapes became popular in the class. When the students are running out, they throw away the meter without knowing it, which is a waste. If I were a scientist, I would invent a stronger digital correction tape to correct the subject by rotation. There is a counter on it, which will decrease as much as it is used up.
In recent years, the world environmental protection organizations have repeatedly advocated a low-carbon life, but people always do not act. If I were a scientist, I would invent a multifunctional car made of full-body solar panels. The solar energy absorbed in the morning is used evenly. If there is any surplus, I can save it and use it at night.
In the second grade, we learned to look up the dictionary according to the phonetic order and radicals, which was too much trouble for students. If I were a scientist, I would invent a convenient multifunctional voice-activated dictionary. If you can't read a word, read its syllables and radicals, and the dictionary will read all its pronunciations and notes in the order of Xinhua dictionary.
If I were a scientist, I would invent the above-mentioned high-tech products to benefit mankind.
If I am a scientist, human beings live in a gregarious society, so everyone should do something that contributes to society. Because people have different interests and aspirations, they choose different careers. For example, some people want to be rich businessmen, some people want to be powerful officials, some people want to be doctors who save lives, some people like to be teachers who train talents, and I want to be a scientist.
If I am a scientist, I want to develop a kind of cheap clothes with adjustable temperature, so that people will feel refreshed in hot weather and warm as spring in severe cold, which will protect the poor from the cold.
If I were a scientist, I would invent a kind of food with high nutrition, so that people would not eat for months, so that they would not be too busy looking for food, and there would be no hungry people in the world. If I were a scientist, I would invent a movable space house, which can be moved to my favorite place at any time. It can not only protect us from storms and fires, but also protect us from floods and earthquakes.
From now on, natural disasters and man-made disasters can't hurt human beings. If my wish can really come true, how wonderful the world will be! I hope scientists all over the world will work with me to make this dream come true at an early date. Isn't that more meaningful than using a lot of manpower and material resources to develop weapons for war?
If I am a scientist and human beings live in a gregarious society, everyone should do something that contributes to society.
If I am a scientist, I want to develop a kind of clothes that can adjust the temperature, so that people will feel cool in hot weather, warm as spring in cold weather, and the poor will not suffer from cold and freezing.
If I were a scientist, I would invent a kind of food with high nutrition, so that people could go without eating for months, and there would be no hungry people in the world.
If I were a scientist, I would invent a movable space house, which can move to our favorite place at any time. It can not only protect us from wind, rain and fire, but also resist floods and earthquakes. From now on, natural disasters and man-made disasters can't hurt human beings.
If I were a scientist, I would develop a small electric flying machine, so that we can fly freely in the sky with it on our backs like dragonflies.
If I were a scientist, I would invent a pill. If blind people take this pill, they can also see this beautiful world like normal people, and the colorful world they long for will belong to them again. People who can't talk can talk after taking this pill. Although I know that there can't be a cure-all pill in the world, I really hope that the pills I invented can be like healthy people as long as they are taken by disabled people. In this way, no one in the world will laugh at them. Perhaps because of this, the word "disability" containing humiliation and pain disappeared from the dictionary.
If my wish can come true, how wonderful the world will be!
If I were a scientist, everyone would like to be forgiven by others after making mistakes, and everyone would like to live in a world full of love.
If I were a scientist, I would invent a "courtesy perfume". If I look at an uncivilized and unsympathetic person, that person will become very kind.
There are beggars on the streets of some cities, which is very pitiful. At this time, I will invent a "folding house" to make the homeless poor people have a warm home like an cartoon.
Some good-looking programs are often shown on TV at the same time. You want to see Journey to the West, I want to see Children at Home, and he wants to see Aliens at Home. I often struggle, and all the good programs are missed. If I were a scientist, I would invent "one TV set with multiple TVs". When there are different opinions, as long as you press the purple button of the remote control, the TV set becomes two, and the remote control becomes two. If you want to become several, just press the yellow button when you want to recover. Good programs can't be wrong.
Some families have children, parents have to go to work, and children are left unattended. If I were a scientist, I would invent a "fully automatic doll". If parents don't have time to take care of their children, dolls can be used as toys and babysitters, and children can still have fun.
Sometimes, there are so many people at home that they are too busy to entertain. This time, I will invent the "robot for entertaining guests". When someone comes home, the robot will automatically pour tea, which brings a lot of convenience to the host.
If I were a scientist, anything I invented would not be too expensive, because it is for the country, the society and the people.
This is a dream, but I will work hard, work hard and work hard again to make my dream come true.
If I were a scientist, I would go to the moon by rocket and see what the moon looks like with my own eyes, but when I look around the moon, a desolate scene comes into view.
There is not a drop of water or air on the moon; It is extremely abnormal that it is hot during the day and cold at night, with a large temperature difference; And there is no life on the moon, alas, I didn't expect the moon to be like this. Seeing this scene, I decided to develop the moon and turn it into the second home of mankind, making the moon as beautiful as the earth. I am a man of my word.
But there is no water on the moon. What shall we do? I went back to the earth by rocket, and let famous scientists invent a machine that can hold as much water as the sea and can be carried with me. The scientist did it at once. We first did an experiment and put a pool of water in it. Nothing has changed, but we can still take it with us. It is not heavy at all. Later, I flew a rocket to the moon. I raised the sprinkler to the highest height, and it rained for 7749 days. There is water on the moon now.
But I have another worry. There is no air on the moon and the temperature is abnormal. What should I do? After much thinking, I made an extra-large air freshener and an extra-large air conditioner. I first put the air freshener on the moon and turned on the button, and the fresh air came out immediately, forming the second atmosphere in the universe. I brought the air conditioner here again and turned on the switch. The temperature on the moon was normal. I don't want to mention how happy I am.
Now that the air and water are available and the temperature is normal, what do I think is missing? Oh, by the way, where do humans live? High-rise buildings should be built. It won't be long before they are built. Smart robots transplanted trees to the moon, which is great.
From now on, I will study hard and strive to realize my dream as soon as possible.
If I were a scientist, I would definitely help people. If I were blind, I would invent an electronic crutch. Blind people are always worried about tripping over or being hit by an invisible car because they can't see. So I will invent electronic crutches to help them. There are three buttons on my electronic crutch. The first button is used for identification. If there is a manhole in front and there is no manhole cover, the electronic crutch will automatically remind you, input the route into your brain and guide you to avoid it. The second button is the navigation button. If you get lost, press the navigation button and tell the crutch where you want to go. It will take you there. The third button is to open your eyes. If there is danger, you can see it by pressing the third button, but it can only last for five minutes.
If I were a deaf person, I would invent an electronic earmuff to help the deaf. If it is an important conversation, the deaf person will wear earmuffs, so that he can hear what others are saying and pass it to your ears through the earmuffs. Although this earmuff has realized the only wish of the deaf, it also has some shortcomings, which are not conducive to his health at this time.
If I were a mute, I would invent a pendant, which could be worn around the mute's neck and used as an ornament. You can also be a "mouth". When you want to talk, you think about it, and this pendant can say it for you. If it's private, don't say it with a "don't say" after it.
If a disabled person lacks his right hand and can't write with his left, use my electronic pen. You just need to draw the words you want to write in the air with a pen in your mouth, read them once, and the electronic pen will help you write them.
Look, this is my wish. I hope I can finish these four things and help more people.
If I were a scientist, I would invent a very convenient car. This kind of car is streamlined and has a cool appearance. Its tail is equipped with four injection tubes, which are specially used for solar power generation. There is a skylight on the roof. If the skylight is closed, the solar panels on it will appear. If it rains on cloudy days, you can also use the previous solar energy to generate electricity. Running forty or fifty miles a minute is faster than an old car. The material of this car is made of a brand-new rubber, which is both strong and elastic. If two cars collide, it will miraculously pop up. I am unscathed. If I were a scientist, I would like to solve the difficulties caused by the earthquake disaster. I want to build a seismograph, which is almost as big as a TV set, and it is very round. Make some balls in each direction. These balls are placed in concave grooves, and they will fall out a few days before the earthquake. According to the direction and angle of the iron ball falling, we can easily guess the location of the earthquake. In order to solve this problem, it is necessary to build the house into various stable figures, use tempered glass as a barrier in the middle of the wall, and then stick rubber on both sides of the glass. Then lay thick floor tiles under the house. Even if the house really collapses, people will not suffocate, because the structure of the house has a chemical reaction with this brick, producing oxygen for people to breathe.
If I were a scientist, I would invent more things.
Such as my scientist composition 14 golden childhood, pure dream, like a colorful flower, weaving a brilliant tomorrow. Tomorrow, I will be a great scientist. ...
If I become a great scientist, I will dedicate all the knowledge I have learned to the scientific cause of the motherland, and use my knowledge to open up a better tomorrow for the scientific cause of China!
If I become a great scientist, I will study how to extract sunlight from cucumber, put it in a sealed bottle, and then release the collected sunlight for use when it rains or the sun dies and can no longer emit sunlight. I believe that in a few decades, I will be able to create a moderately soft sunshine to shine on the big garden of this world.
If I become a great scientist, I will also study how to make clothes with spider silk, because I think it is a bit wasteful for people to make clothes with silk all the time, because dyeing is extremely troublesome. I will feed all kinds of flies to spiders, so that spiders can weave different colors of silk without dyeing.
If I become a great scientist, I will also study how to turn air into a dry and touchable object; Study how to soften marble into pillows or blankets; Study how to sow and grow crops with chaff. ...
If I become a great scientist ...
If I were a scientist, I would make a multifunctional insect trap. Of course, it's not catching bugs, but the thief we hate most.
Nowadays, there are more and more thieves and people's troubles are becoming more and more. Sometimes, at night, when people are asleep, there may be a pair of eyes staring at you, or just after you fall asleep, a pair of black hands will touch your precious safe without mercy. Steal your things while you are asleep.
If I am a scientist, you need not be afraid. With my multifunctional insect trap, you can sit back and relax.
Its structure is extremely novel and looks like a robot. It relies on two "feet" to support balance, holding him tightly, and those "hands" are attached to the white wall by the door.
Don't underestimate its function! Its belly is equipped with a "sound insulation device", which can make it ready to attack him through the thief's voice, and then directly judge whether he is a thief through the "sensor" on his body. It won't take long to judge. It only takes about 1~3 seconds to judge that there is a long "tail" dragging on the ground behind him, which can be used as a rope to directly bind the thief. He also has the best function, that is, he can call the police automatically, so that the police can judge the specific location of the thief as quickly as possible.
If I were a scientist, I would recommend my multifunctional "insect trap" to everyone, without spending a lot of money, all for free.
If I were a scientist, I would not only invent multifunctional insect traps, but also invent many useful things for people.
If I were a scientist, I would make people's lives colorful.
