Composition with excellent haze

In study, work or life, everyone is familiar with writing. Writing is an important means to cultivate people's observation, association, imagination, thinking and memory. I believe writing a composition is a headache for many people. The following is my excellent smog composition for reference only. Let's have a look.

In the morning, I stretched myself and walked out of the house. I thought it was snow all over the sky. People are like walking into a dreamland, surrounded by "fog". For example, there is a "veil" in front of you, and you can't see the distance clearly. Don't think what I said is good. In fact, the white "fog" and "veil" are disgusting smog!

Good mood has a lot to do with good weather. For several days in a row, going to school in the morning was all white, and I couldn't see the distance, the tall buildings, and the flowers and grass that were still growing tenaciously in winter. But I can only see the exhaust of cars, the smoke from chemical plants, and people wearing masks rushing by. ......

It seems that all creatures are crying!

The sky is crying, the trees are crying, the white clouds are crying and the animals are crying. Everything is crying under the veil of smog. What caused it? Why are these innocent "lives" crying? People are asking this question, but we all think that others have polluted our air. How many people think about themselves? Your every move, one careless and one indifferent, pollutes your own air and everyone's air? The culprit is none other than human beings!

"The values of PM2 and 5 have seriously exceeded the standard! Please pay attention to the people or things around you that pollute our air! " It was on the news, it was in the newspaper, and everyone said it, but did we supervise it ourselves? Every household will set off firecrackers during the Spring Festival, right? How many families don't set off firecrackers for our air and our own air? Have a car. There are more and more families with cars in today's society. Cars are running on the road, with exhaust gas all the way. How many people drive less for our air and our own air? Smoke from big factories and small factories, automobile exhaust. Have you ever thought for yourself, have you done these things? How much pollution has it caused to our beautiful city?

Factory owners! Pick up the conscience that fell to the ground! Wake up! People blinded by interests! Give Mother Nature a healthy body, and also give our next generation a healthy body! Don't let the beautiful earth destroy! Don't let your children and grandchildren have bad health! Let you be the chief culprit in destroying the air!

Why was the air so good before? This can only be said because I used to be poor. I didn't have a car because I was poor before. Because I was poor before, there was no factory. Because we used to be poor, human beings will not fight to the death for their own interests, or even destroy the air for their own interests!

All for one and one for all. As long as we all have a "degree" in our hearts, tomorrow's society will be better!

On Wednesday night, my mother received a short message from the Education Bureau. Nanjing primary and secondary schools were completely suspended because the air pollution level was upgraded to a red warning. I am surprised and happy to hear this news, because I don't have to go to school tomorrow, so I can sleep in. But how is the smog formed? What impact and harm does it have on our lives?

I finally know the reason for the smog: 1. Dust accounts for 30%. 50%, mainly from road traffic, buildings, exposed ground, etc. 2。 Industry accounts for 29. 7%, mainly coal-fired emissions and dust and organic matter produced in production. 3。 Motor vehicles account for 23. 35%, mainly refers to the exhaust emissions. 4。 Civil accounts for 10. 8%, mainly refers to the coal-fired emissions of small coal stoves and boilers. 5。 Others account for 5. 7%, mainly refers to the catering, dry cleaning and other emissions. According to newspaper reports, before the 1990s, the average annual haze weather remained within 100 days, but in June this year, the haze weather has risen to 186 days. As can be seen from the data, our environmental pollution is getting more and more serious, and there are more and more haze weather, and the environment on which we live has been severely tested.

Smog weather has brought a lot of inconvenience and harm to our lives. In these two days, we can hear news reports every day. The number of highway closures, airport closures and traffic accidents is also increasing, and even the number of people running red lights is increasing. When there is fog, people are afraid to go outside. Everyone is hiding at home, and the scattered pedestrians on the street are wearing masks and rushing. If there is no smog, we can have normal classes and go to physical education class happily with our classmates on the playground. Parents at the weekend can also take me to travel to the suburbs. The foggy weather makes everything impossible.

Hazy weather has brought us a lot of losses. According to the newspaper, these pollutions are caused by ourselves, so if we want to have more blue sky and white clouds and breathe more fresh air, I think we should do it: drive less, walk more, ride more bicycles and use more environmentally friendly and green means of transportation. Protect the forest, plant more trees, cut less trees, and plant more green plants around us. It is necessary to reduce construction and avoid dust.

Protecting the environment is a top priority. Let's all act.

I'm sure everyone will feel very strange when they see the topic. Want to know why? Then look down!

I woke up early yesterday morning, ready to go to the balcony to breathe fresh air. I can't wait to open the glass door, "yi? Why is it so stuffy today? What about this color? " No, I have a bad feeling when I see this weather. Oh! Oh, my God, it can't be smog!

First of all, let me introduce a smog. In my mind, fog is a particularly beautiful and wonderful thing, especially in the mountains. If I meet Miss Fog, it will be like being in the jade emperor's paradise. Everything is so beautiful, but what if you add a word "haze"? Haze is polluted air, which is gray at first glance. The air contains small sediment, which will enter the eyes when the wind blows.

These days in Beijing, there are only five days without fog. It is reported that less than 1% of the 500 largest cities in China meet the air quality standards of the World Health Organization. If people don't take some wise measures, then one day, the earth will be surrounded by the devil of smoke.

So why is there smog? It's because of humans. Humans! Being labeled as "destroying the environment and wasting resources", do you still want to be the title of "the initiator of smog"? Because of people's greed, factories, power plants and chemical plants began to go crazy, almost all over every city. They arrogantly emit toxic gases, exhaust gas from human cars, gorgeous fireworks and human barbecues, resulting in pm2. The value of 5 rises linearly. People kill themselves for a period of time to satisfy themselves!

It's hard to see the sky and lift it,

Pedestrians are helpless to wear masks.

Where is the smog everywhere?

The ecological environment was destroyed.

The earth, the mother of mankind, is so amiable, great and kind. She selflessly provided us with resources, and we not only failed to return, but also ruined her.

Now many people are aware of this problem and often shout the slogan of protecting the earth, but no one has done it. So, from now on, let's act. Protect Mother Earth together. If you are a pupil, please call on everyone to take care of the environment. If you are a farmer, please join us in planting the first tree in the deserted desert, making it impossible. If you are a civil servant, please mobilize everyone to fight this bad guy together.

Please remember that although the fog of nature is beautiful, it has become an abominable evil ghost because of some behaviors of people.

Fog? Haze.

Looking at the gloomy sky and gray surroundings, is this still my hometown?

Once we get to that sky, we can talk to the white clouds and sing with the birds. But now, there is nothing but the gray world. And it is human beings who plunder all this, not us.

When you are immersed in the excitement of setting off firecrackers, have you ever thought that the ashes inside are turning into small particles? When you drive smartly in the countryside, have you ever thought that harmful substances in automobile exhaust are becoming small particles? And these hundreds of small particles, slowly, formed a bomb-smog.

The bomb exploded, can it be saved? Sure！ Sure! And we are frugal.

If we don't set off fireworks and firecrackers in the New Year, wouldn't it be much better to use family games instead than playing exciting and dangerous firecrackers outside? If you give up a luxury car and ride a bike together when you travel, is it much better than a heavy and airtight car? What if these are not hypotheses, not ifs, but true?

In the morning, what wakes you up is the chirping voice of birds, "chirp, lazy scum, get up and chirp". Helpless, stretch to bid farewell to the warm bed. Open the window, look at the green, and let the sleepy eyes "wake up". Unconsciously touching his pocket, holding a mask, oh, no, because Wan Li is cloudless and sunny outside the window. Take a deep breath, fresh, refreshing, as if filtered, with a faint floral fragrance. Huh? A naughty little ladybug flew to her finger, turned left and right, and looked up at herself. Hey, good morning. All right, let him keep flying. After releasing the ladybug, look at your hands. Hands without fog are so slender and beautiful. Gee, I'm late for my date with my little friend. Go downstairs and take out my bike. Look at the green grass, colorful flowers and green trees, look up at the white clouds, hey, good morning! When riding a bike, there is no fog or haze, only fresh air. Run wild!

Looking at the blue sky and white clouds, this is my hometown-Suzhou.

Recently, severe smog has always enveloped the whole city of Beijing. Every morning when I get up and open the window, the room will be filled with smog, which makes my throat itch and I feel unspeakable sadness.

Beijing "locks" the city in smog, and the visibility in most areas is less than 200 meters. Affected by smog, the urban area is caught in serious air pollution, and all seven monitoring points in the city are in a state of "serious pollution". In Hangzhou, although the sun is shining, the buildings seem to be covered with gauze. Every day when I go out, I feel the air is dry and the sky is gray, like flying dust. Because of the high ground humidity and low wind speed in Hangzhou, it is not conducive to the smog dissipation, so the smog days last for a long time. The travel advice given by the environmental protection department is to "cancel unnecessary outdoor activities". This makes us feel bad.

The streets are sparsely populated, with fewer people and fewer cars. Everyone who goes out is "fully armed", wearing masks, scarves, hats and gloves. The continuous smog weather has caused many people to suffer from respiratory diseases, mostly the elderly and children. The hospital is crowded with people, and the pediatric door is crowded with hundreds of children. This scene is comparable to "Spring Festival travel rush fever". According to statistics, nearly half of the patients in recent days are patients with respiratory diseases, and their clinical manifestations are mostly fever, cough and runny nose, as well as upper respiratory diseases, bronchitis, bronchopneumonia and asthmatic pneumonia. Compared with the same period last year, the number of patients with respiratory diseases has increased by 30% this year.

Fog or haze is a kind of disastrous weather, which will reduce air quality and affect the ecological environment. There are often bacteria and viruses in the air, which can easily lead to the spread of infectious diseases and many diseases. In winter, when encountering fog and haze weather, if encountering serious air pollution, poisonous fog such as smoke or black smoke may be formed, which seriously threatens people's lives and health.

Students must not be afraid, smog can also be prevented. I suggest you hide in foggy weather, don't get up early to exercise and reduce outdoor activities. If you have to go out in foggy weather, you'd better wear a mask to prevent poisonous fog from invading your lungs through your nose and mouth. On weekdays, you need to supplement some vitamins properly and eat more such as oranges, kiwis, green peppers and spinach. It is good for the body to discharge dust particles.

Now, I believe everyone has a certain understanding of smog. Let's join hands to protect the environment and "drive away" the terrible smog!

On the afternoon of March 27th, we came to the lecture on "Earth Hour" in the stepped classroom on the sixth floor of our school with great interest.

In the solemn staircase classroom on the sixth floor, the school invited a teacher Chen to give us a lecture on "How the smog is produced". After listening to the lecture, everyone was filled with emotion. The atmosphere in the sky is polluted by exhaust gas because children's parents drive more cars, and it is also polluted by many uncivilized and unsanitary habits, which makes the atmosphere emit smog that is harmful to health. The teacher asked us, "Who can tell me how to have my own awareness of prevention?" Many students raised their hands and answered questions enthusiastically. Everyone gave different answers, including "don't spit everywhere", "wear a mask when going out" and "close the doors and windows at home" ......

After listening to these answers, the teachers all said yes, and the children's answers were great! But it's different from what I think in my mind, such as: open more windows, stay away from the factory where I work, stay away from burning coal ..... My mind is still full of questions?

At this time, there is a question floating on the blackboard: how can we reduce smog? What I just thought is fine. I raised my hand in a hurry. The teacher didn't seem to notice me, but chose Lin Wenlong behind me to answer. He replied: "drive less private cars, ride more bicycles and take more buses." If you are close, you can go! " After that, thunderous applause rang out from the audience, and my sister next to me sent me a bag of beautiful gifts, which made me envious!

How can we reduce smog? Smog is mainly caused by air pollution. It really depends on everyone's same idea to reduce smog. I think we should start from each of us, and we can do it in our own homes: form the habit of speaking hygiene from an early age, don't spit everywhere, and plant more trees! Drive less and walk more!

This activity has increased our knowledge! * * * The same appeal: "Turn off the lights for an hour!" This is the concept of energy saving! No matter where you use electricity, saving electricity requires our long-term efforts and support. Always remind yourself to turn off unnecessary lights and unplug unnecessary power! Small changes can have a huge impact!

I hope Mr. Haze will go away quickly! Can make us grow up healthily!

In the morning, I saw a foggy scene. Mother is fiddling with the pot of chrysanthemums that came back to life in the yard. She smiled and said, "This is really the feeling of seeing flowers in the fog." I am silent and depressed, and I can't feel the hazy beauty that my mother refers to. I can't say why I don't like fog. Think about it carefully, maybe it's because it always reminds me of my late grandmother.

I sat quietly, immersed in distant but clear memories.

Before I went to primary school, I lived in the country with my grandmother. This is a very remote and quiet small village, full of natural and peaceful atmosphere everywhere. Green wheat fields and warm and pleasant winds are unforgettable. The most beautiful thing is that the people here are kind, simple and enthusiastic, especially Grandma Ba. When I was five or six years old, refrigerators selling ice cream were popular in the village. Every time I come out to play, I ask Grandma Ba to bring me a cheap popsicle. Grandma Ba loves me and says I'm likable. She often lets me taste her popsicle for free. Now that I think about it, maybe she loves me so much not because I am likable, but because I look like her granddaughter. Eight grandmothers live alone, one son died unexpectedly for many years, and only one daughter lives in the city. My daughter is married and has children, so she seldom comes back from work. I often see Grandma Ba calling her daughter on the fixed telephone at home, and what she says is almost the same every time. Generally, Grandma Ba will ask her daughter if she has taken stomach medicine on time, ask her granddaughter if she is well and when she will go home, but usually the conclusion is "OK, you are busy, you are busy, and mom is dead." Sometimes Grandma Ba will sit still for a few minutes after hanging up the phone, and sometimes she will turn her head and secretly wipe her tears. I always thought Grandma Ba would spend the rest of her life peacefully, but there are always too many surprises in life.

When I got up that morning, I saw my grandmother sitting in front of the door with tearful eyes. I asked grandma what happened. Wiping away tears, she said that Grandma Ba passed away this morning. I have never experienced such a realistic parting of life and death. I just stood there for a long time, and I couldn't move. I didn't start crying until grandma held me in her arms. It turned out that in the early morning, Grandma Ba sent her daughter her favorite Chili sauce by bike in the fog. Unexpectedly, a car hit her in a daze, leaving her no chance to say the last word. Her daughter cried at the funeral. However, no matter how sad she is, she can't get her mother back. Since then, I have never eaten such a delicious popsicle. The taste of popsicles has long been blurred, but people who sell popsicles can't forget it for a long time.

I really don't know how much affection will be blocked by covering half of China for a long time!

In recent years, with the gradual deterioration of air quality, the phenomenon of haze weather has appeared more and more frequently. They invade the respiratory tract and lungs of the human body unsuspecting, thus causing respiratory diseases, cardiovascular diseases, blood system, reproductive system and other diseases, such as pharyngitis, emphysema, asthma, rhinitis, bronchitis and other inflammation. Long-term exposure to this environment will also induce lung cancer, myocardial ischemia and injury. -inscription

PM2 is full of smog in winter. The explosion rate of 5 is quite high, and the air visibility is very low. Many people travel with thick masks. Ma Lao and I don't like masks, because we are glasses brothers. After wearing a mask, a layer of water vapor is formed on the lens when we breathe, so it is not convenient to talk when wearing a mask. My family has repeatedly reminded me that I don't want to wear it.

Riding on the road with the old horse last week, I found that almost every rider wore a mask, which made us look different without it. The visibility on the road is very poor, and the bridge 100 meters away is looming. The old horse laughed at himself for "not going with the flow and not following the crowd", but I was a little nervous. If this continues, will the respiratory tract be uncomfortable? Will my cough recur? How many people know the pain of coughing?

After riding for three days, it feels a little strange. My throat seems to be stuck by a foreign body, getting tighter and tighter, and I can't breathe. I coughed several times. This feeling is never seen when the air is fresh! There seems to be something stuck in my throat. I can't cough up, I can't swallow it, and it's very uncomfortable. The old horse was stronger than me, but it couldn't hold on the next day and was defeated in front of the smog. My old horse and I stopped riding bicycles and took a family car instead. I coughed wildly as soon as I met you, as if complaining about the smog. Later, the two men coughed and said goodbye to each other.

I want to write a composition for the Chinese exam. I can't calm down because I keep coughing, so I write slowly. Similarly, coughing also bothers others, and many students cast their eyes at me to express their dissatisfaction. Oh, I'm sorry. I have to repay their helpless eyes to apologize. After class, some students still avoid me. Dust and smog enter the respiratory tract, which makes me psychologically afraid. News reports say that these inhalable particles, once in the body, are difficult to remove; And the high incidence of respiratory diseases caused by air pollution is on the rise, which is really scary!

My mother cooked three bowls of mung bean soup and lily soup for me to stop my cough. After drinking, the symptoms only eased for three hours, and the cough recurred. Hazy days make me cough. In fact, wearing a mask is only a temporary protective measure, not a long-term solution. Masks may be more psychological comfort. Only by solving the air pollution at its root can we truly bid farewell to the terrible smog.

Fog is actually a non-toxic and harmless natural phenomenon, and the formation of smog is mainly the result of a large number of suspended particles in the air and meteorological conditions. Smog is often accompanied by smog at the same time. Conditions such as water vapor, still wind, inversion temperature and condensation nuclei are indispensable. -inscription

Hazy weather has brought us all kinds of troubles. Now everyone starts to panic as soon as they hear the smog weather. But how is the haze weather formed? I don't know! Then listen to me and tell you slowly, but I didn't know until I checked a lot of information.

It is because the relative humidity is not large when the smog occurs, but it is saturated in the fog (if there are a lot of condensation nuclei, the relative humidity may not reach 100%, which may lead to saturation).

Generally speaking, the visibility deterioration caused by atmospheric haze blurred vision is caused by haze when the relative humidity is less than 80%, while the visibility deterioration caused by atmospheric haze blurred vision is caused by fog when the relative humidity is more than 90%. The visibility deterioration caused by atmospheric haze blurred vision is caused by a mixture of haze and fog when the relative humidity is between 80 and 90%, but its main component is haze. The thickness of smog is relatively thick, which can reach about 1-3 km. Haze is different from fog and clouds, and there is no obvious boundary between haze and clear sky. The distribution of smog particles is relatively uniform, and the scale of smog particles is relatively small, from 0. 00 1 micron to 10 micron, with an average diameter of about 1-2 micron, and no floating particles can be seen by naked eyes. Because the smog is composed of dust, sulfuric acid, nitric acid and other particles, the longer the scattering wavelength, the more the light ratio, so the smog looks yellow or orange-gray.

There are three elements in the formation of smog: one is the physical basic source of particulate matter. China has the largest loess plateau area in the world, and its soil texture is the easiest to produce granular dust particles. Second, poor exercise leads to dust. For example, the mud in the garden in the middle of the road and the soil on the roadside stones will flow to the road after raining or splashing water, which will produce a lot of dust after one hour of drying. Even if these particles fall back to the ground, they will be thrown over the city again because of the continuous passing of cars. Thirdly, the basic source of dust and the process of movement difference gather in a certain spatial range, and particles finally gather with water molecules to form haze. At present, in more than 350 cities in the Loess Plateau of China, the three elements of smog structure are quite rich.

As for the smog weather, we also suffer from it, but how are these caused? It's not just the pollution damage caused by human destruction of the environment ... Let's act together to protect the living environment on which we live. I believe that as long as we can protect our living environment, we will be able to stay away from the smog weather!

Not long ago, a friend in the north showed off their "smog holiday" to me, and he was jealous when he told me how carefree he was at home. Unexpectedly, as soon as he sent me a photo of the city, the envy in his heart suddenly disappeared and was replaced by happiness. I am glad that the city without tall buildings in the photo is not here. I am glad that I don't live in a place where I can't even see the bus stop clearly when I go out.

At least here, we can breathe the air that is not seriously polluted, and look out into the distance that is not covered by PM2 5. We can play outdoors and stare at our lover's face on the park path. I always feel that smog makes all romance and joy a dream and fantasy.

After listening to the weather here, my friend told me his longing for sunny days. But is the environment in the south necessarily good?

In the cold winter, the front of the unit building is not a withered camphor tree with no leaves all year round, but a simple white gauze with water everywhere. Under the black canopy, the whole world seems to be splashed with delicate gray pigment, as if it can be covered on clothes, stuck on hair and covered on skin at any time, which makes people avoid it, but when they want to hide, they find there is nowhere to hide. Sometimes when it is dawn, the extremely uncomfortable white gauze still does not disappear, which continues to erode people's vision and sense of smell, and even makes me feel uncomfortable breathing.

After this happened many times, the number of people wearing masks at school increased, and my mother bought me some masks, which made me very helpless.

One morning, my mother saw me out. She looked up and said, "I can't see the sky now!" " "I also looked up, looked down, and finally shook my head, don't want to talk. Now in the winter city, it seems that there are many crazy PM2 in one mouth. Pour five pills into my mouth. These little things sometimes falsely grab a drop or two of water around them, disguise them as fog with superb skills, and then enter the open mouth with great fanfare, symbolically wiping a few lines of coolness on my mouth, but what haunts my body and mind is the pollution caused by their "body odor".

I don't remember when the word smog began to spread to the north and south of the river. In recent years, it has already become a big star, and it is developing in the direction of red and purple, and its development and expansion seem to be unparalleled.

Today, with the continuous improvement of living standards, when will smog become history and when will it no longer appear? I hope we can enjoy the blue sky forever from one day.

Fog 1 1 Fog fell from the sky like a silent tsunami, which flooded the whole city.

Li Er casually tidied up the books in the bookcase, while looking at the vast expanse of whiteness outside the window, thinking about the blue sky and the fresh wind mixed with soil. Growing up in the countryside, she sighed lightly, her tail still dragging in the air. "Cough", people have been coughing violently.

After dropping out of school, in order to support his family, Li Er came to the city and got a job as a nanny. The salary was not bad, but the air here was unbearable for Li Er, especially in foggy days.

Li Er got out of bed in the morning, and when his sleepy eyes opened, he was scared. There is only a vague outline left outside the window, everything is shrouded in dense fog, and the air is so humid that people feel drowning. There seems to be a lot of caterpillars crawling in Li's throat.

On the way to his employer's home, Li Er heard nothing but intermittent cough. Usually busy roads are much quieter, except for a few faint lights flashing intermittently.

After finishing the bookcase, Li Er, who knows a few words, carefully opened an expensive book. She doesn't know why these books are dusty but brand new. Has Mr. Li never read it? Then why buy the books in this study? "Huhu" heard Mr. Wang's snoring in the next room. I must have drunk too much again. Li Er sniffed the rich smell of wine in the air and thought, I really deserve to be an official. He snores rhythmically. I really envy him. I didn't see him wearing a shiny suit, driving his Mercedes to work several times, and still so rich.

Li Er shook his head and crept downstairs for fear of waking the Buddha.

The luxurious living room is in a mess. Colorful rubbish is scattered on the smooth marble floor, and sofas and tables are filled with all kinds of gifts. Take a closer look, Li Er got a fright again. Although it is not the first time, she still can't help admiring these cigarettes and alcohol that are higher than her monthly salary.

However, pure Li Er has never been moved. She skillfully rolled up her sleeves and began to work hard. It is still thundering upstairs. Li Er has cleaned everything, leaving only one window for Mr. Wang's most precious things.

When Li Er picked up the rag and saw the glittering trophy, she was shocked by the environmental protection contribution award and gave it to Comrade Wu Wang, the director of the Environmental Protection Bureau who had worked hard for our city.

Outside the glass window, the sky is vast, the ground is vast, and the wind blows the leaves and no one is seen.

In fact, smog is not only in the air, but also hidden in society.
