8 words on smog (1)

Looking at the newspapers in recent days, I found that the air pollution is getting worse and worse, and the air quality index in Hangzhou is declining. Why on earth? It turns out that this is all a ghost caused by smog.

what exactly is smog? How harmful is it? How is the haze weather formed? What can we do to dare to walk in the foggy weather? Through the collection of information and my own understanding, I found the answer.

It turns out that smog is a combination of fog and haze. Because of the deterioration of air quality, the phenomenon of smog weather has increased and the harm has increased. In many areas of China, the phenomenon of haze weather is combined with fog as the early warning and forecast of disastrous weather. Collectively referred to as "haze weather". The harm of smog is great! Due to smog, light fog, sandstorm, sand blowing, floating dust, smoke and other weather phenomena, visibility is poor due to the influence of a large number of extremely fine dust particles or smoke particles floating in the air. When driving, traffic accidents may be caused due to poor visibility. Haze is harmful to human body after inhaling into human respiratory tract, and serious inhalation for a long time will lead to death. Therefore, when the smog weather comes, we should be less active outdoors. If we must go out, we must wear masks. Open the window less and take more vitamins. These are all good ways to prevent smog!

how is this harmful smog formed? A large part of it is caused by ourselves. There are five reasons for this: < P > First, the main factor is that the atmospheric air pressure is low and the air does not flow. Because the air does not flow, the tiny particles in the air gather and float in the air.

second, the ground is dusty and the air humidity is low. People and traffic on the ground stir up the dust.

Third, automobile exhaust is the main pollutant emission. In recent years, there are more and more automobiles in cities, and the automobile exhaust is a factor of smog.

fourth, the secondary pollution produced by the factory.

5. CO2 and other pollutants emitted by heating in winter.

Among them, Article 2345 is caused by us humans, so should we reduce these behaviors and contribute to the control of air pollution?

Now, there are too many cars in the city, and the exhaust emissions cause air pollution. We should advocate green travel, use public transportation as much as possible when going out, and be able to ride bicycles, so as to effectively reduce the degree of air pollution.

The motherland is our home, and we should protect it. Let's travel green and reduce exhaust emissions. Let our home be more beautiful!

8-word argumentative paper on smog (II)

"If you walk a dog, you can't see the dog; if you see the rope, you can't see your hand, and the dog tells me to leave"

This is the most famous saying about smog recently.

when I get up in the morning, I open the curtains and look out the window. It feels like I'm blind. I can't see the blue sky or the long white clouds. There is chaos between heaven and earth, and everything is gray. Even the colorful building opposite has only a hazy outline.

Before we know it, smog has quietly enveloped the whole city.

before going to school every day, you should be fully armed for fear that the smog will be sucked into your lungs. But, what's the use?

The cars on the road are still whirring with exhaust gas, and the factories in the distance are constantly emitting black smoke. The trees on both sides of the road can't be seen, and people are wearing white masks.

so, how did this disgusting smog come about?

Many of our families have cars, but while we are sitting in the cars and preparing to travel, the exhaust from our cars is quietly contributing to the smog behind us.

In the remote suburbs of the city, some chemical plants are "showing their talents", and the thick black smoke emitted day and night is slowly merging into the air.

At the fireworks show on New Year's Day, the colorful fireworks and crackling firecrackers made the air smoky and very turbid, and the air quality dropped sharply. These are the main causes of smog. They bring us quick, convenient and pleasing to the eye, but they also quietly bring us unexpected consequences.

in foggy weather, we breathe turbid gas. Haze in the air can cause diseases such as pneumonia. In 1952, the smog-like invisible killer in London, England, took 4, lives in just five days and 8, lives in the next two months. We can see how powerful smog is.

the smog is so serious, how can we prevent it?

We should wear masks, eat light food and drink plenty of water when we go out. In the foggy weather, we should open the window less for ventilation. But also appropriate vitamin D supplementation. When you come back from the outside, wash your hands, face and gargle. And we must reduce outdoor activities. If you must exercise, you can do indoor exercises.

What we want is fresh air and a healthy body. Please don't sacrifice your health for the so-called good life. Drive less, travel green, plant more trees and protect forests. Cure smog, start with me.

Recently, the weather in the north is always foggy. When I get up in the morning, the beautiful scenery around me becomes very blurred, and the news frequently reports the serious consequences caused by the continuous appearance of smog weather. The smog weather has seriously affected the air quality in the north and affected people's normal life. Especially in Beijing, smog weather occurs almost every day. Beijing, which we call the capital, has become a foggy city!

In recent years, smog weather not only seriously affects the air quality, but also is the main source of diseases such as asthma. The air in foggy weather contains some tiny particles in the form of dust, which we can't see with the naked eye. These tiny particles are enough to make people get lung disease. They can be called invisible killers. So, what is the smog weather caused by? In fact, the smog weather is formed by car tails, cooking fumes, smoke from smoking and fireworks, which leads to the emergence of smog weather.

don't say that smog weather is a killer, not to mention that smog weather is terrible. In fact, the real killer is us human beings. It is human beings who don't know how to protect the environment. It is human beings who want to destroy their homes, so it causes smog weather. These are all the consequences of human beings.

of course, the present situation is still irreversible, and we can still stop the smog weather. We can change the car to ride a bike; You can eat stew instead of cooking; You can quit smoking or put the cigarette butts in the trash can after smoking; You can put less fireworks and firecrackers; You can also plant more flowers and trees to purify the environment. Only if we choose a low-carbon life can we prevent the occurrence of haze weather. Sometimes, I really hope that what comes out of the car is not bad tail gas, but faint fragrance, and what comes out of the chimney is not thick black smoke, but crystal dew. I really hope that our home will become greener, redder, and the birds' songs more beautiful and melodious.

I believe that our dreams will come true only if we take action and start from ourselves. Let's work together to protect the environment and defend our homeland, so that the smog weather will no longer harm the world and make our homeland better.

8-word argument on smog (4)

Dear smog:

I can only see a vast expanse of whiteness in front of me, and I can't see anything clearly, just like being in a misty Penglai fairyland.

Haze, I know it's you.

your white, smoky appearance has long impressed me deeply. But I don't like you and I hate you very much.

Although you come from a scholarly family, your parents are well known. Mother Fog, who lives in the forest, is beautiful and moving like a fairy. The father who lives in the city has both a rough and heroic side and a gentle and careful side. But not only did you not inherit the beauty and gentleness of your parents, but you were also naughty.

Beijing has become your home. In the morning, just before dawn, the warm sunshine is preparing to wake up the sleeping earth. In an instant, the earth turned white again, as if wearing a white brocade. What's going on here?

I know, it's you. You cover the rising sun, the warm sunshine and the vitality of the earth ...

You cover the whole of Beijing, and you can't tell the boundaries between heaven and earth, and you can't see the roads, Woods and figures clearly. You still feel proud, don't you? Do you know the consequences?

there is an invisible ""in your body, which is made up of dust in the air. After people suck your huge body, it will do harm to their own bodies, especially children and the elderly. If you suck too much, it will cause cancer and cause upper respiratory tract infection. Also, you cover the streets and lanes, and it is very easy to have traffic accidents.

Fortunately, people in Beijing are not bad, and they know how to avoid you: 1. Try not to go out or open the window. 2. Be sure to wear a mask when going out. 3. Do not drive to avoid traffic accidents. And other safety awareness.

how many people can't live a normal life because of your prank? So everyone hates you, even hates you. You made their families sick, you prevented them from breathing fresh air, and you made them live in disastrous weather phenomena forever ...

I hope you can turn over a new leaf and become as beautiful as mother fog and as gentle as father haze. Go where you should go, find a world that belongs to you, and don't disturb our life again.

goodbye! We will always remember you.

smog 8-word argumentative paper (5)

"smog red alert, Nanjing primary and secondary schools are closed today"

"what! Wow! Great! " After hearing this sentence, the whole class was boiling. But some people still don't believe their ears. They ran to the classmate who read this exciting news with a newspaper, stared at the words in the newspaper for a long time, and finally cheered again.

but I'm not happy at all when I hear the news.

smog, worthy of the name, is the floorboard of fog and haze. But fog and haze are not the same substance, and their differences are great.

Haze is haze, that is, some dust and sundries in the air are mixed together. Looking from a distance, it looks like a sea of clouds in Huangshan Mountain, which makes people mistakenly think that they are in the clouds. However, haze is different from clouds after all, and its harm is not small. As you can imagine, traffic accidents are inevitable if the road is muddy. People breathing in those harmful substances is also a kind of harm to physical and mental health. Haze is also divided into many levels, including mild haze, mild haze, moderate haze and severe haze. After I watched the news, I found that the city in Shanghai was shrouded in fog, but it was only moderately hazy. It can be seen that if it was severely hazy, what shocking things would happen in that gray and dark scene.

as for fog, it often appears in our Nanjing area. It is formed by small water droplets liquefied by water vapor in the air when it is cold and suspended in the air layer close to the ground, just like the clouds on the ground, a vast expanse of whiteness. According to the different characteristics of fog, fog can be divided into many types, including radiation fog, advection fog, evaporation fog, smoke and so on. Of course, its harm is not small. Unknown substances drifting in the air can induce symptoms like colds and asthma. It's hard for me, who has been catching a cold and coughing recently.

It's good that fog and haze are so frightening to separate. This time, Nanjing has caused smog! Su Shi, a great poet, has to sigh when he encounters smog, not to mention those students who can only follow the arrangement of the school eagerly.

Haze is one of the most important things in our life. It combines all the characteristics of fog and haze, and its harm to human body is even worse. We all know cancer, which is an incurable disease that makes people talk about canceration. Smog can really cause cancer-smog, which consists of a lot of dust, impurities, toxic particles and exhaust from urban life, will cause some diseases if it is often inhaled by people, and cancer is of course the "top predator" among these diseases.

Of course, the formation of smog is also inseparable from the "credit" of people in life! For example, the tail gas emitted by vehicles, a lot of harmful gases from factories when producing things, and many roads are dusty all over the sky, but the relevant departments never arrange people to clean them up.

If people don't pay attention to this, maybe smog will come and become a "natural law".

Here, I hope my dear classmates can do a good job of maintenance and cleaning in time, and at the same time, they can also wait for the good news of returning home after the smog counterattack.
