Every time I see the miasma of the city I especially hope that there will be an air purifier, not the kind used at home, but a more powerful one that can solve the problem of pollution in our environment.
Now people are tormented by air pollution pain, the exhaust produced by cars, smoke from forest fires, soot ...... can pollute the air, to our human health hazards. And my air purifier at this time can produce a big role, it is not like the kind of air purifier at home, can only absorb the indoor carbon dioxide, as long as the air pollution in serious places, such as: the road, factories ...... install an air purifier, and then in everyone's clothes, hairbrush, and even shoes, install a mini carbon dioxide transmitter, when people get to a place where the air pollution index reaches over the standard, the mini carbon dioxide transmitter will transmit the surrounding carbon dioxide to the air purifier, which will turn the carbon dioxide into fresh oxygen. Let people as bathing in the forest, enjoy the forest bath.
Speaking of which, I'm afraid that people who love beauty will worry that the mini CO2 transmitter will affect the beauty of your clothes, right? There is no need to worry, because my carbon dioxide transmitter is a thousand times smaller than the ants ten thousand times, with the naked eye can not be seen. And the air purifier is only the size of a box, so it won't get in the way.
If my air purifier is really invented one day in the future. Then, Beijing may never have haze again, and people will not be distressed by air pollution, and breathe healthy air every day.
I hope that day can come soon, and I hope scientists can work harder to research this air purifier with powerful functions.

The future of science and technology
The future is always bright, the future of science and technology will be more and more developed, so what kind of advanced scientific instruments will there be in the future?
Now the haze is getting more and more serious, many cities are dim pressure a piece of the horror of the "gray devil" engulfed, shrouded in a depressing gray environment. The consequences of the haze are very serious, the impact on the human respiratory system and the harm to the cardiovascular system can not be ignored. I hope that in the future we can invent a kind of environment. tester to guarantee a healthy living environment. Every car, every factory must have a tester, wait until the exhaust emissions from this car or the sewage and exhaust emissions from this factory reach a certain level will issue a warning, then the owner must stop working. *** There will be a lot of "vacuum cleaners", and every once in a while, people will fly in airplanes with "vacuum cleaners" in the sky and wipe out all kinds of dust. Perhaps also may invent a magic brush, like the magic brush Ma Liang, as long as in the barren and withered flowers and trees on a few strokes, here will be magically and quickly become new, flowers and grasses, branches and leaves, full of vitality. If there are these wonderful tools, nature will not be "haze killer" threat, become vibrant, birds and flowers, fresh air, so that people's physical and mental comfort. Appreciate the blue sky and white clouds, flowers, willows, streams, and feel the infinite vitality and beauty of nature.
I also hope to invent a health detector. Nowadays, workers are under great pressure and heavy burden, and they die suddenly at a young age. This health detector is convenient and lightweight, and can be carried around. If a person more than reasonable working hours, it will remind you how to reasonably choose with vegetables and meat, and remind you to maintain sufficient sleep time, so that you always have a healthy body. If you ignore its tips, it will nag you to reason and tell you, "Health is the capital of life, with a healthy body to work better." Until you accept the tip will stop nagging.
The future is bright and full of hope, we have to study hard, with wisdom and sweat, **** create a better future!

5. Write an essay on "If I were a scientist"If I were a scientist, I would make an air purifier to clean the air in the city. Now, air pollution in our country is getting more and more serious.
Before attacking the technology of the purification machine, I encountered a problem: how to turn the exhaust into fresh air? Coincidentally, I saw a tree planted in front of the door, I slapped my head and shouted: "There is a way!" I extracted a substance from the leaves of the tree and called it folliculin. It was folliculin that allowed the tree to freshen the air. I integrated the lutein with the machine and made a purification machine.
Of course, I had to test the purification machine to see if it had this function or not. So I installed it on the exhaust pipe of the car, I got in the car and started the fire, and then got out of the car and went behind the exhaust pipe and smelled it, and sure enough, what came out of the exhaust pipe wasn't exhaust gas, but fresh air!
I immediately asked Bobbi the Robot and her buddies to build seven purification machines that were ten times larger than an airplane. They are with remote control, I want them to go where they go, where the air needs to be purified where they go. However, the purification machines have another disadvantage: they consume electricity. I send the purifiers to the sky because the wind in the sky can charge the purifiers. But the machine still comes down once a week to purify the air.
Now, the air in our country is getting cleaner and cleaner
6. Control the air 130 wordsSample essay, for reference only:
Do you realize that the environment around us is getting more and more seriously damaged? Indiscriminate felling of trees, pollution of water and air, destruction of ecological environment and so on. Countless facts have told us that environmental protection can not be delayed, the protection of the environment is not only the state and *** department's responsibility, but also our "arch" citizen's responsibility.
In the past few days, I have been investigating the extent of air pollution around us and the danger of air pollution to human health. I according to the environmental characteristics of the surrounding Zhuhai and found the problem, the Internet to carry out the investigation. Analyzing from the survey, the air around us is polluted. The main sources of pollution are the black smoke emitted from factory chimneys and the exhaust vapor from motor vehicles. What pollutants are emitted from these sources? What are the hazards to people's health? I consulted the relevant information, know a lot about air pollution knowledge.
The main pollutants in the atmosphere are carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides and particulate matter. If their content in the air exceeds a certain standard, it will jeopardize people's health. Air pollution index is less than 50, indicating that the air is good, the concentration of pollutants is less than the ambient air quality standards in the first standard limit, for the first class, in line with the nature reserves, scenic spots and other areas in need of special protection of air quality requirements Air pollution index is greater than 50, less than 100, indicating that the air quality of the general pollutant concentration is less than the ambient air quality standards in the second standard limit for the second class Good, in line with the air quality requirements of urban residential areas, mixed commercial and transportation residential areas, cultural areas, general industrial areas and rural areas.
Prevention and control of air pollution, control of pollution emissions is to improve air quality fundamental measures, the main ways are: rational layout of industry, good environmental planning to change the energy structure, the promotion of cleaner fuels, the use of cleaner production processes, reduce pollutant emissions to strengthen the energy saving, improve energy efficiency, centralized district heating heating to strengthen the supervision and management of the environment and the treatment of old sources of pollution, the implementation of the total amount of control and Up to standard emissions strict control of motor vehicle emissions, etc..
Zhuhai is our "home", should build her better. But the air pollution problem is very serious, what should be done? I suggest:
(1) engage in three-dimensional greening, expanding the green area, you can engage in soilless culture. Plants have filtered a variety of toxic and harmful air pollutants and purify the air function, the woods are particularly significant, so greening and afforestation is the prevention and control of air pollution is a more economical and effective measures.
(2) solve the fuel problem, try to use solar energy and other non-polluting or less polluting energy.
(3) Organize more publicity campaigns and consultation activities to enhance people's awareness of environmental protection.
(4) Organize students to pick up garbage in the streets, markets and squares on their days off to keep the environment clean.
Today we are the masters of tomorrow's society, to protect and improve the surrounding environment is our generation's duty and obligation. We have to start from me, from the small things around us, do environmental protection, pay attention to saving resources, recycling waste products, more participation in environmental protection activities, more planting, more flowers, do a veritable environmental protection little guardian it!
7. I want clean air essayWe are the most intelligent creatures on the earth, we dominate the billions of years of history of the earth. But we always forget that we are insignificant to the earth, we constantly take from the earth, we constantly destroy the earth, and behind these actions, hidden is the serious consequences of the extinction of mankind!
What we can't live without on Earth is air. It nourishes us and enables us to smell different odors. But now, walking on the road, smell the smell, no longer mixed with the fragrance of flower petals, only disgusting garbage flavor. The air, which cannot be seen or touched, has turned into rolling smoke. The blue sky is no longer pure and is occupied by gray smoke. This not only affects our physical and mental health, but also causes serious harm to the earth! The reason for such a consequence is that human beings build a lot of factories, and the smoke from the factories floats into the sky. A large number of automobiles are traveling on the road, and the exhaust from the automobiles combines with the air. A large amount of garbage is piled up in the river, on the road and other places, where "temporary shelter" is built. ......
Humans for their own interests without regard to the overall situation. The fact is that the people of the world are not the only ones who are not in a position to do so, but they are the only ones who are not in a position to do so. In order to reach their own fast and convenient destination, let the car exhaust in the air floating around. For the sake of your own convenience in taking out the garbage, let the garbage wander in the streets, alleys, streams and rivers. To purify the air, we can reduce the smoke emitted by factories. Drive less, try not to go to the car, the best choice is to ride a bicycle or walk, which not only reduces the emission of automobile exhaust, but also can exercise your body. Categorize garbage: renewable resources, non-renewable resources. So that garbage will no longer pile up on the streets, flies will no longer harass passers-by, and garbage will no longer block the rivers and pollute the water. Plant more trees to purify the air, so that more trees, for us to create a fresh home!
For us, for our children and grandchildren, we have to purify the air, be a civilized and polite people.
8. To "environmental protection from the side" write a compositionLet the green spread to the end of the world, let the birds free shuttle - environmental protection
Two oriole song cui willow, a line of egrets on the blue sky. Listening to this string of cries, y evoked my yearning for spring, the green hope. Birds, you are the messenger of spring, is the symbol of spring, is the nature of the elf".
Once upon a time, we had such a pure sky, such a moving song, such a beautiful bird; we have experienced so much beauty and touching; in the embrace of nature, our mood is so calm and cheerful. Spring, that is the voice from the sky. "Thousands of warblers crying green and red, water village Guo wine flag wind," a few crisp cries, will be sung drunk in the spring of Jiangnan, confused with the smoke and rain of the Southern Dynasties. The tired people wandering in the rivers and lakes, the return of the traveler, no counting on the date of return, are all slammed heart.
Ancient people still know that birds bring life, bring green; green is the fundamental continuation of life, boast of smart modern people how to forget it? Today, there is not a bird flying through the city's sky. Birds where have you gone?
A piece of forest fell down and disappeared. Rows and rows of cold, towering buildings protruding; a lake dried up, replaced by a monster spewing black smoke; birds chirping can no longer be heard, into the ear drums are full of metal machines hoarse hiss. Every corner of the city, piled up rich also piled up machinery.
The wheel of the times is running at a high speed, and people are in a hurry, with the desire to travel under the gray roofs of the city. No one will look up and see the sky; no one will stop and pay attention to the sun. Nature? Spring? The song of the birds? It was all so strange. Yes, strange! "Spring is in our house all the time" - so modern people would say. Yes, the heating in winter, the cold in summer, air purifier ......, a good artificially produced spring, a lifeless spring, a virtual spring that can never hear the bird cries!
The city can no longer hear the song of the birds. Only the children are still babbling and singing: "Little swallows, wearing flowery clothes, come here in the spring every year ......" Is it still possible for these tender hearts to nourish the spring? However, they have to grow up, perhaps one day, they will also be like birds, in the steel and concrete from the forest to lose themselves. So what should we do for our future generations? Only action, for environmental protection to make their own obligations, then that beautiful and touching will be again we appreciate, we can again in the embrace of nature, the mood will become more calm and cheerful, people and talents will be more united and harmonious life on this planet.
Otherwise, the city's sky, there really will not be a bird flying over, far away, there will also be a spring that has been left behind for a long time in the - gently sobbing ......
Chinese people have long known that " Things in people", now, in the face of this spring flying dust and sand, after the fall table full of dust, why do not we "for" on a for it? For us and for our children and grandchildren, take action! "Where are you, bird?" "Where are you, bird?" is no longer a question, is it? Let the green spread to the end of the world, let the birds free to travel!
9. Write a 500-word essay about describing the airI love the air
We live in a forest of concrete and steel, and we are far away from the vibrant trees. Nowadays, transportation, buildings or complex machinery all bring great pollution to the air, although they all bring us convenience, but have you ever thought that they will also pollute the air is harmful to the human body.
At this moment, some scientists have developed and invented many items and machines that can purify the air, and people can use these things to suck the harmful objects out of the air, and then discharge the fresh air, so that the air is more refreshing. But we human beings can't rely on these tools, and it's not that we can cut down trees indiscriminately with these tools. Because every tree is very important to us, no big trees to protect the soil, the soil will be washed away by the river; no big trees to beautify the environment, people live in the miasma of the earth; no big trees to maintain the ecological environment, the animals will gradually scarce ...... in this way, then more machines are useless. Nowadays, air pollution is so strong, we have heard of "air pollution, global warming"! If the air pollution is too strong, the earth will gradually warm, then the Antarctic and the Arctic glaciers will melt, our homes will be flooded, so the whole earth is a vast sea, we will be like a myth, riding on the "Noah's Ark" in the sea drift. So it is important to purify the air for us, we need to plant more trees to make the air cleaner.
Let us *** with the planting of trees, protect the beautiful nature, care for grass and trees, so that the oasis in the desert increased, everyone together to participate in it!
