Hazy composition

In life, work and study, everyone will inevitably come into contact with composition. Composition is the transition from internal speech to external speech, that is, from a compressed, concise language that they can understand to a developed, standardized grammatical structure that others can understand. Do you know how to write a good composition? The following is my carefully compiled composition about smog for your reference, hoping to help friends in need.

When I was a child, grandma always told me that fog is the most beautiful.

As a result, every foggy morning, I will get up early and go downstairs to suck the air greedily. Ah, the flowers, the grass, the freshness of the earth and even the songs of birds are full of it. The nose is wet and cold. My eyes never let go of this fleeting opportunity, and I can't appreciate enough the wonders like Penglai Wonderland. The fly in the ointment is that the fog disappeared clean before I remembered it (I was lazy at that time and slept until eight o'clock every day).

There has been little fog since I was in primary school. In the fifth and sixth grades, I didn't see it once. Fog doesn't seem to appear in the weather forecast.

On the third day of this year, firecrackers never stopped. Covered on the bed, I looked out of the window and jumped up at once. Fog! I ran downstairs as fast as I could. I seem to be back to my childhood, sucking the air greedily ... A burst of disappointment came to my heart, and there was no familiar smell in my memory, and I didn't feel wet and cool. I only breathed in my nose and kept coughing. I looked around and realized that I was the only one without a mask. A white-collar worker with a briefcase was in a hurry, wrapped in two masks, and his eyes were full of horror, as if to escape from the devil's clutches.

What? Fog is a demon? I ran upstairs with a grain of salt and turned on the computer. "It's sometimes cloudy today, PM2. The 5 index is a new high in half a month. " I lay in bed feebly, looking up at the sky. The soft, transparent and ethereal fairy is gone, replaced by this dark, turbid and ferocious demon. His men broke into my nose and damaged my young and healthy body. After reading the introduction of smog, I suddenly felt that the festive firecrackers were not festive, and seemed to be singing a sad song for the earth. Gray sky, at first glance, my heart hurts ... a tear falls from the corner of my eye. Maybe the air is too dry. I think.

The fog is gone forever, so is my childhood, and so is the childhood of the earth. Both the earth and I will grow up and destroy all the roots of evil.

In a blink of an eye, winter is coming, which is our children's favorite season, making snowmen and having snowball fights. However, this year, we didn't have so much fun. We stay indoors most of the time. Let's see what happened.

We often see thick fog in the street. Walking in the street is like being in a fairyland. However, white fog is not a good thing, it just prevents us from playing. Needless to say, this is the nasty smog.

I think everyone knows something about smog. Smoke is made up of some tiny particles in the air. These tiny particles make the atmosphere turbid and form smog. Simply put, the main cause of smog is too much dust on the ground.

Smoke will bring us a lot of trouble. First of all, what bothers us most is that smog makes our travel very inconvenient. Walking in the street during the day, I can't see my fingers, and the surrounding buildings are shrouded in fog. Looking out through the window at home, it's like a fairyland outside. The fog has drowned everything, only white fog can be seen. These are nothing. What's more disturbing is that the smog ruined our travel plan. Because of the foggy weather, the plane had to continue flying, and all we saw at a scenic spot was white fog.

Smog not only brings inconvenience to our travel, but also does great harm to our health. Now, as long as the haze weather happens, most people don't come out at home. Even if you want to come out, wear a mask to prevent inhalation of dust. In this way, smog is really annoying!

Now, let's work together, for our health, for the environment of the city, for the convenience of our travel, and for us to breathe fresher air. Start by picking up a piece of waste paper under your feet, don't litter, plant a variety of trees, drive as little as possible, and reduce the emission of automobile exhaust ... Let's drive away the smog together and bid farewell to those days of walking in white fog.

Let's work together to bid farewell to smog and make our home better!

There is an essay about smog. Recently, the media often reports information about smog. I heard many reports about smog weather. Then I consulted relevant materials and information and got some understanding of smog. The smog phenomenon also has a negative effect on people's health, so it is necessary to effectively control smog.

Sulfur dioxide. Nitrogen oxides and inhalable particles are the three main components of smog, and the former is gaseous pollutants. The last one is that particulate matter is the chief culprit of smog weather pollution at home. When they combine with fog, the weather becomes dark and the sun can't be seen. This particle itself is a pollutant and a heavy metal, and these diameters are less than or equal to 2. Wulanwu, with a diameter of 5 microns, is the source of heavy metals and toxic particles in this city. The first is automobile exhaust. Cars that use diesel are archways and recidivists of fine particles. Small cars that use gasoline emit nitrogen oxides, but in foggy days, they are easily converted into pollutants of secondary particles, which aggravates smog.

The causes of smog are complex and simple. It is human greed that caused such a disaster. Desire is the root of all evil. We should restrain our desires, for example, cutting down trees less and not setting off fireworks. Entrepreneurs should grasp their conscience, reduce air pollution caused by chemicals, or drive small-displacement cars and live a low-carbon life. As a country, we should not only aim at GDP, but also organically combine spiritual civilization and material civilization to purify the social atmosphere. I believe that everyone should do their best for this society. It is everyone's responsibility to protect the environment and raise environmental awareness. I believe that one day the smog will be far away from us.

These days, the fog has filled the whole campus, and it seems that rain can be smelled in the humid air. Especially when you travel in the morning, half of the roads are foggy, and you can't see people or the surrounding greenery. During the day, the lights are also on. In order to prevent the fog from spreading, all the campuses in the city have entered the smog area these days.

Although people have made great efforts to protect the environment, it can't be completed overnight. In the past, a large number of trees were cut down and roads and bridges were built, which increased the silt in the river bed. Once it rains, the riverbank will be out of control, and the river will overflow into the fields, causing no small flood disaster. Moreover, under the influence of chemical enterprises, the air quality is greatly reduced, more and more houses are built, greening is gradually replaced by high-rise buildings, chimneys, waste gas and garbage follow one after another, so there is smog.

The smog is made by human beings, so it can be said that he is innocent. Because he stayed in the atmosphere well, at most, he turned into a drop of water and fell to the ground, which could also moisten the earth. I don't want a lot of exhaust gas to rush into the clouds and make him mutate, so I have the later smog theory. Haze, known as the invisible killer of air, is extremely wronged. It is obviously a mistake made by human beings. Why should he bear it? Now human beings have an understanding of protecting the environment and are alert to protecting their homes, but what should we do with more and more buildings and less planting area and greening? I hope that mankind will reflect and take practical actions to protect Mother Earth.

After reading it, did you see the harm of smog?

There is an essay about smog. When the sky in Beijing is shrouded in smog, the sunlight is too weak to penetrate the air. Tiananmen Square, the Great Wall, the Forbidden City ... Everything is looming, and the sky above the city is always gloomy. On a foggy day, people walk outside, afraid to take a big breath of air, and don't even put their clothes outside to dry. Old people don't go for a walk, and children don't play games.

The first snow in year of the snake, slowly falling from the sky. In the morning, the sky is so blue and clear, the air is so fresh, the sun shines on me, birds cheer in the treetops, and the sun comes back to me. I feel the warmth and sunny mood brought by the sunshine quietly, hoping that the sunshine will always be bright.

The smog came again, and the sun hid in the clouds again.

When our team is holding an interview activity, captain Zhao Yaqi is telling us the process of the activity. I don't know why, the two boys in the group have been laughing, and Zhao Yaqi reminds us to be quiet! The two boys quieted down. Zhao Yaqi went on to say, look back at them, we are impatient, and urge her to hurry up. As a result, Zhao Yaqi got up and left in a rage, leaving a sentence: "Hurry up, this venue was reserved by my mother. If you don't leave, you will owe me one! " We didn't like her talking like that and went back to school. Afterwards, my heart was overcast and "smog" was heavy. "Are we going too far?" I thought to myself, "She has prepared a lot for us, too." I called her to apologize, and she realized her mistake, so my mood was particularly clear.

When I found that my skipping performance was not as good as before, I felt a little gray, but I didn't lose heart. I practiced harder, but when my grades picked up, the "haze" cleared away. He forgave me after I accidentally bumped into someone. At this time, the "smog" is gone forever. ...

At this moment, I looked out of the window, and it was sunny outside. The sunshine is bright and colorful, and our life is full of sunshine, which makes us full of passion for life, gratitude for everything in the world and warmth for everything.

There is an essay about smog. During this period, smog weather generally appeared in most parts of China. The usual blue sky is always gray now, and the number of sick people is gradually increasing.

Do you know what smoke is made of? If you don't know, I'll tell you what smog is made of.

Haze is composed of particles such as ash, sulfuric acid, nitric acid and organic carbon oxides in the air.

These harmful particles are caused by our usual failure to protect the environment, deforestation, garbage invasion, sewage discharge, destroying fields and burning bricks.

Minimize going out in foggy days, and wear cotton masks when going out to prevent the respiratory tract from being "polluted" in foggy days. Wash your face and bare skin in time when you come back from going out, or rinse your nose with clear water. Morning exercise in foggy days will not only lead to respiratory diseases, but also lead to cardiovascular and cerebrovascular diseases; Smog weather should minimize the number of people going to many places, and poor air circulation in some places can easily lead to cross-infection of respiratory diseases. Drink more water, have a light diet, eat more fresh fruits and vegetables, and exercise more to enhance immunity.

Haze is very harmful to human body. Once these deposits enter our bodies, they can never be excreted. You can wear a mask when you go out, which can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean. When you come back from going out, you should wash your face and expose your skin immediately.

We should protect the environment, plant more trees, cut down fewer trees and save every piece of paper, every drop of water and every kilowatt hour. Don't let the hateful smog appear again!

There is an essay about smog. 7. Terrible smog.

The weather today is really strange. It is still cloudy in the morning. At about 6 pm, a thin layer of fog gradually appeared on the horizon, covering the distant hills.

I thought it was the night that covered the horizon. After five minutes, when I leaned over the window and looked into the distance again, I accidentally found some small granular water droplets on the window glass. After careful study, I found that every droplet contains a small black dust particle, which makes me curious. Looking further away, the tall building seems to be tied with soft white gauze, and the neon-dotted ribbons are more and more ethereal; Cars passing by the parking lot also turned on fog lights, and the light emitted was like a light beam, which was very attractive. It's getting dark, and the water drops on the window are gathering more and more. Slowly, more and more water droplets are sucked. Everything outside the window is so quiet and beautiful, I can't help but be deeply attracted ... just as I was intoxicated, a flash of lightning flashed across the sky, accompanied by lightning, and heavy rain poured down. The rain beat against the glass and the dust was washed away. The fog just now has been blown away.

Hey, isn't this the smog phenomenon mentioned in the nature book?

I dug up a thick book "100,000 Why" at home. Ha, finally found it-yes, this is smog! It is because a large number of particles, such as smoke and dust, are suspended in the air, which blurs the line of sight and reduces the visibility. No wonder there are particles on the window glass. It turns out that the dust in the air is at work!

Because the more serious air pollution is now, the more foggy weather there will be, and the greater the harm. Sometimes cars can't drive and planes can't land.

In order to reduce smog weather, we must protect the environment, plant more trees and grass, improve air quality and benefit mankind. I hope students can deeply realize how bad our environment is through this composition about smog, I hope.

I hope students can protect the environment.

There is an essay about smog. Because the air quality is seriously polluted, it has caused haze weather. So the Education Bureau informed us to suspend classes, so we had to do our homework and read books at home. When I looked out of the window, I suddenly found that there was a "gray world" outside, and even the opposite building had only a hazy outline. This kind of weather is more and more frequent, and the smog silently hangs over our city. The environment around us has been seriously damaged, and Mother Earth is ill.

My mother and I went out to buy some daily necessities. My mother said that smog weather can cause respiratory diseases and asked me to wear a mask. Even wearing a mask, I still smell a strong smell of "roasted salted fish", which is very uncomfortable. When I got home, I felt my head burning like smoke. My mother measured my head with her body temperature. Oh, dear! I really have a fever. I had a long rest at home before my fever went down. This shows how powerful the smog is!

Haze is a turbid phenomenon formed by a large number of particles such as smoke and dust suspended in fog. How is the smog formed? Many families own cars, which makes our travel much more convenient, but the exhaust emissions of cars pollute the air; Power plants, oil refineries, chemical plants and other factories "show their talents" in our city, emitting smoke and dust day and night; Gorgeous fireworks are dazzling, but the air is full of smoke and becomes very turbid. These are the main reasons for smog. They have brought us quickness, convenience and pleasure, but they have also quietly brought us unexpected consequences. In order to see the blue sky and white clouds again, to have a healthy body and for our next generation, we should drive less, travel green, plant more trees and protect the forest. Cure haze, start from me! Let's work together in Qi Xin to protect the environment and care for the earth! May our mother earth be beautiful forever! Sky blue and clear water forever!

There is an essay about smog. Nine health care methods in foggy weather

Less windows in foggy days

Many people are used to opening windows for ventilation. But if the smog lasts all day, should I open the window for ventilation or close the doors and windows? Zhi Li pointed out that it is not recommended to open the window for ventilation in the morning and evening in foggy days, and it is best to wait until the sun comes out before opening the window. wear a mask when going outside

You can wear a mask when you go out, which can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean.

When you come back from going out, you should wash your face and expose your skin immediately.

Appropriate vitamin d supplementation

This season is foggy and sunny. Due to insufficient ultraviolet radiation and insufficient vitamin D in the human body, some people will experience mental laziness and depression. Vitamin d can be supplemented if necessary.

Have a light diet and drink plenty of water.

The diet in foggy days should choose light and digestible foods rich in vitamins, drink plenty of water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also play a role in moistening the lungs, resolving phlegm, relieving cough, strengthening the spleen and tonifying the kidney. Eat less irritating food and eat more pears, loquats, oranges, oranges and other foods.

It is easy to cause cardiovascular diseases

Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy days, and it is not suitable for morning exercise, otherwise it may induce diseases and even heart attacks, which may be life-threatening. Experts pointed out that foggy days are the "dangerous period" for patients with cardiovascular diseases because foggy days are depressed and the oxygen content in the air drops, which makes people feel chest tightness easily. The wet and cold fog in the morning can also cause cold stimulation, which can easily lead to vasospasm, blood pressure fluctuation and increased heart load. At the same time, some pathogens in fog can cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially the elderly and infirm, should not go out in foggy days, let alone do morning exercises in foggy days to avoid danger.

There is an essay about smog 10. I got up in a good mood this morning, but when I looked out of the window, my warm heart suddenly cooled down, because today I met my most annoying weather-smog.

Many articles describe fog as soft, but why is it not as soft as the fog in the article? In fact, this is a very good problem to solve, and the answer is related to everyone's usual living organs: automobile exhaust, toxic gases emitted by chemical plants and dust will all cause smog. Tomorrow afternoon will be the same, but this morning almost scared me to death. Here's the thing. "

Early this morning, I got up in a good mood and looked out of the window. I hope to see the opposite buildings and early risers. But what I saw was completely different from what I hoped. What I actually saw was a white scene. Our family lives on the sixth floor, which is not very high, but from the balcony, we can't even see the tall trees. Dad told me that today's weather is very polluted, so I need to wear a mask, or I will get bronchitis and other diseases. So I put on a mask. Because I'm going to the Children's Palace to learn dance, my father has to drive, which is what I fear most: as soon as I get on the bus, I look out from the front windshield, and the visibility is less than 200 meters, which is so scary! I'm sure my father must be nervous when driving a truck. In fact, I am also very nervous, because I have never seen such terrible weather since I was a child. I was too nervous to catch my breath all the way to school. I will never see such weather again, so I must start from myself and from my side. I know that I can't protect our motherland alone, and my strength is insignificant, but if we protect the environment together, it will play a huge role!
