Three hundred words on a foggy morning.

In the morning, I walked in endless fog and hurried to school. Because of the smog, one-third of the people on the road wear masks, and there are cars on the road. The sun disappeared and the whole world fell into a gray world.

When I arrived at school, the morning run that the students expected had to be changed to let the students do indoor sports in the classroom because of the serious smog. Everyone's interest was suddenly suppressed by the smog. What is even more frightening is that the students who get along with each other day and night are also sick one by one. First I caught a cold, then I went to the hospital with a fever. There are 46 students in our class, and several students can't come to school because of illness. The pungent smell of vinegar and the disgusting smell of disinfectant in the classroom make our mood very gloomy. Even I, who is usually in good health, have a slight cold.

I once did a little experiment. On my way to school, I saw a traffic jam. My eyes were fixed on a black BMW, and I remembered the last three digits of the license plate to see who would get to the crossroads first. I walked quickly on the road and looked back at the car I left behind. Finally, I reached the crossroads before the bus. This experiment shows that cars are not necessarily the fastest means of transportation. When the distance is not long, riding a bike and walking may be faster than driving. But also can exercise, so why not?

But also can exercise, so why not?

In the third grade of primary school, my father took his brother and sister to play. Because of the smog, the play plan was cancelled and the brother and sister chatted. ...

It has been foggy in Xi for the past two weeks. In the morning, it was very cold and dark.

I found that people around me were wearing anti-fog masks, and now I can't go running because of the smog.

My mother told me that my father has been ordering anti-fog masks online for the past two days, giving them to him in black, to my mother in blue and to me in pink.

Hearing this, my heart is depressed, like a gray haze.

However, I think if Lan is a monster, the Monkey King in Journey to the West will definitely kill it with a golden hoop.

Haze is poisonous. If you smoke too much, it is not good for your health, and you will get sick. If you are covered in smoke, it will lead to death.

I read these from page 622 of the medical books in my father's bookcase.

I suggest that people in cities drive fewer cars, trucks and other cars that emit exhaust gas. If it is really inconvenient, they can ride bicycles, so they don't have to emit exhaust gas.

I remind everyone: "drive less exhaust cars, smog will not come, blue sky and white clouds will come back!" " "Today's weather is really strange. It is still a mist in the morning. At half past noon, a thin layer of fog gradually disappeared from the horizon and shrouded in the distance. I thought it was foggy for five minutes.

When I squatted by the window again and looked into the distance, I accidentally found some small granular water droplets on the window glass. After careful study, each droplet contains a small white dust particle. I'm surprised. The water drops on the window accumulate more and more, and slowly, more and more water drops are allowed to be sucked. Everything outside the window is so beautiful that I can't help being deeply attracted ...? Isn't this the smog phenomenon mentioned in the nature book? I dug up a thick book "100,000 Why" at home. Ha, I found it. This is smog. It is caused by a large amount of smoke suspended in the air. Smog is very harmful to human body, so students should protect the environment! The smog weather for a period of time has made everyone who just got up in the morning and longed for fresh air almost a wish and an expectation. Everyone has to wear a mask to deal with this smog-shrouded city, which brings a lot of inconvenience to our lives.

I asked my mother, what is the cause of smog weather? My mother told me that due to the transitional development of human beings, environmental pollution, industrial pollution, automobile exhaust emissions and so on, we could not see the blue sky and white clouds, but looked up and saw the haze weather.

If you are not careful, people will have respiratory diseases.

In order to let us breathe fresh air and see the clear sky, we should protect our surrounding environment, reduce pollution and drive less, so that our air can be purified quickly.

Diary of three 600-word compositions about smog weather

Hazy weather From the end of 20 12 to the beginning of 20 13, the sky all over the country seems to be shrouded in "smog". This is the first time I have heard this word from news reports, and I also know the harm of "smog", which makes people more worried and cautious when traveling.

It's foggy outside the window, and you can't see anything at the distance of 100 meters; People in the house were depressed. Instead of seeing the sun, they thought of the night with the moon.

I remember when I was a child, the roads were not so wide, the buildings were not so dense, and the night sky was not so chaotic and fuzzy.

At that time, the sky was dark blue, especially in summer nights. The stars are shining, scattered, spectacular and beautiful.

Standing on the roadside, I always look at the sky and forget to come back.

Strange to say, I gradually found that at night with the moon, all the stars hid, only occasionally seeing the brightest one. Where did everyone else go? Did they go home? Sometimes I think.

Later, when I grew up, I had more troubles and worries. I prefer to watch quietly for a while, think for a while, sleep for a while, and have a sweet dream with the moon at night! The moon is sometimes round like a jade plate, sometimes it lacks a moon cake that looks like a mouthful, and sometimes it bends like a boat. At that time, it is particularly eager to be Chang 'e in the sky, hoping to accompany her and grow up together in the nearest place to the moon.

The night with the moon gives people peace, comfort, light, coolness and good mood.

"I don't know the heavenly palace, where is it tonight?" I've always wanted to make a song about wine, as chic and cheerful as a poet, but the reality in reality always pulls people around and entangles them.

Ah! Everything is gone! Whether the moon rises today or tomorrow, there is always the shadow, mood and appearance of the moon in my heart.

Let the moon in my heart always be on, neither rising nor falling, and I will always live as safely and comfortably as the moon!

Chai Jing smog survey composition is 450 words in grade six.

Recently, the weather is always foggy. When I get up in the morning, the beautiful scenery around me becomes blurred. The news also frequently reports the serious consequences caused by the persistent smog weather, which has seriously affected the air quality and people's normal life. In recent years, smog weather not only seriously affects air quality, but also is the main source of asthma and other diseases. It contains some tiny particles like dust that we can't see with our naked eyes. These tiny particles are enough to make people get lung disease. They can be called invisible killers. So, what caused the smog weather? In fact, the haze weather is formed by automobile exhaust, cooking fume, smoke from smoking and fireworks, which leads to the appearance of haze 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, who don't know how to protect the environment and want to destroy their homes, leading to haze weather. Of course, these are the consequences of human beings. You can eat stew instead of cooking; You can quit smoking or put cigarette butts in the trash can after smoking; You can put less fireworks and firecrackers; We can also plant more flowers and trees to purify the environment. Only by choosing a low-carbon life can smog weather be prevented. Sometimes, I really hope that the smoke from the car is not unpleasant exhaust, but a faint fragrance. The smoke from the chimney is not thick black smoke, but crystal dew. I really hope that our home will become greener, flowers will be redder and birds' songs will be more beautiful and melodious. I believe. Our dream will come true. 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. Don't forget to import Puwei Xintian from America when traveling.

Beautiful Zhen 'an needs 200 words for her third grade composition.

Speaking of hometown, it's really distinctive.

Especially in winter, the beauty of hometown is a beautiful world in the snow.

There are snowflakes during the day, sometimes falling one by one, and sometimes thick snowflakes can make a snowman and play unscrupulously.

You can also use a cardboard box as a skateboard; Slide down from a height like a sprint.

That kind of speed and * * * are my favorite feelings.

The snow at night is beautiful, and the moonlight hits the snow, just like the light in the dark, charming and warm.

Just like putting new clothes on the road and adding gorgeous lights at night; China New Year is a splendid fireworks and wonderful music, which makes people smile.

This scene is the most prominent scene of Chinese New Year every year.

There are also lifelike ice sculptures along the road.

They all have their own characteristics and significance: look at that good horse! It seems to run before our eyes, telling us the spirit of perseverance.

Look at Nu Wa Niangniang! Caressing a baby.

Just like a kind mother caressing her beloved child.

I really want to tell us the goodness of being a man and the greatness of my mother.

Look at the gate with lanterns hanging! This means that no matter where you are, you must have a China heart.

Look at that beautiful fish! Spitting bubbles symbolizes that you have more money this year and all your wishes come true! This is my lovely hometown, my favorite season all year round, and my snow country!

The best observation diary of the third grade composition is a belly.

Early in the morning, I looked out against the first ray of sunshine in the morning and looked around. I saw several colorful sunflowers floating in the blue sky. The sun quietly revealed its beautiful face. Several mountains in front of the village are looming in the morning fog, and I can vaguely see the lush forest. The air is so fresh, the earth is full of vitality ... when Mother Earth selflessly makes all this beautiful, I am lost in thought. Her body has also suffered great damage: environmental degradation, land desertification, air pollution, species extinction, forest disappearance … and the culprit of these evil deeds is the human raised by Mother Earth! It's people themselves! Look, the towering chimney emits thick black smoke, which smokes away the flying birds and covers the vast sky; Look! In the past, the crystal clear stream became black and smelly, and small fish could not survive and were homeless; Listen! With the "creak, creak" sound of the chainsaw, tall and green trees collapsed, a forest gradually disappeared, leaving only bare loess and birds' homes gone ... because of human industrial pollution, the air is deteriorating, the beautiful scenery is gradually disappearing, and the clean stream is gone, gone! Due to human deforestation, vegetation loss, soil erosion and land desertification have been caused. Floods and sandstorms have devoured people's lives, and only a few bare stumps can be seen in the sand! Because of the improvement of human living standards and technology, automobile exhaust pollutes the air, and smog is a disaster for human beings. Animals are gradually extinct, and flowers and trees are gradually disappearing! What caused all this? ! This is people's insatiable ambition and growing greed! But besides the people who destroy the environment, there are also a group of people who protect the environment, but compared with the people who destroy the environment, they are nothing.

Today, the earth of 2 1 century depends on our joint efforts to make her beauty never die!

The method of controlling smog is 600 words.

1. Looking out of the window, I suddenly found that I couldn't see the blue sky and white clouds. There is a gray scene between heaven and earth, and even the opposite building has only a hazy outline.

This kind of weather is more and more frequent, and the smog silently hangs over our city.

Haze is a turbid phenomenon formed by a large number of particles such as smoke and dust suspended in fog.

According to the remote sensing satellite monitoring of the Ministry of Environmental Protection: 65438+29 10, our country10.3 million square kilometers was shrouded in smog, and the air quality was seriously polluted.

How did the foggy weather come about? Many families own cars, which makes our travel more convenient, but the exhaust emissions of cars pollute the air; Power plants, oil refineries and chemical plants "do their best" in our city, but soot and dust are discharged day and night; Gorgeous fireworks and firecrackers are dazzling, but the air is full of smoke, which becomes very turbid, the air quality drops sharply, and the indexes of PM2.5 and PM 10 rise linearly. These are the main reasons for smog. They have brought us convenience and pleasure, but they have also quietly brought us unexpected consequences.

In foggy days, we breathe turbid gas.

The smog in the air can cause pneumonia, pharyngolaryngitis, bronchitis, heart failure and other diseases.

1952, the invisible killer in London, England took 4,000 lives in just five days, and took 8,000 lives in the next two months. It can be seen that the power of fog should also sound the alarm for us.

What we want is fresh air and good health.

Please don't sacrifice your health for the so-called good life.

Drive less, travel green, plant more trees and protect forests.

To cure haze, start with me.

2. Another foggy weather with insufficient visibility 100 meters.

No matter the vehicles or pedestrians are groping forward, there is no laughter or bird singing. In such an environment, there are only pungent smells and dim eyes.

Fog, originally like light smoke, like gauze, like a scarf, hangs over the earth.

Throughout the ages, it has fascinated and fascinated many literati.

The current smog seems to have something to do with this beautiful fog. What heinous crime has it committed? Haze seems to have a "blood relationship" with fog, but it is completely different from fog.

Fog is water vapor condensate composed of small water droplets or ice crystals floating in the air.

Sometimes fog indicates sunny days, sometimes fog indicates rainy days, and it looks chaotic. However, as long as we master the characteristics of radiation fog and advection fog, observe in many aspects and analyze carefully, we can accurately grasp the laws of fog, sunny and rainy weather, and then predict the weather.

This is very useful for agriculture, transportation, aerospace and navigation.

The smog is different. It is a small ash particle composed of dust, sulfuric acid, nitric acid and organic hydrocarbons in the air.

Let's talk about the harm of smog-first of all, long-term smog weather can easily lead to respiratory infections, cardiovascular diseases, asthma, bronchitis and other diseases, which is very harmful to human health.

Secondly, in foggy days, it is easy to have a car accident.

The tiny ash particles floating in the air are hard to see. It is also common that you can't see each other clearly when riding a bike or driving, so the appearance of smog weather can easily make the two cars "close contact".

Third, when there is smog, the whole sky is gray, which makes people feel very bad ... the culprit of diseases and car accidents, can we watch it exist in our lives? No, you can't.

So, it's time to stop the smog weather! Drive less and walk more; Cut down less trees, plant more trees ... Protecting the environment is the root of smog control! So we should save as much as possible and be as environmentally friendly as possible.

Let's work together in Qi Xin to protect the environment and the earth! May our global village be pure forever! Sky blue and clear water forever! If the smog weather is not stopped, then one day, the planet we live in will definitely become an abandoned planet surrounded by dust.

Humans would not exist.

Finally, I ask you to remember that there is only one earth for human beings! 3. Eight ways to deal with foggy days: First, avoid morning exercises in foggy days.

The amount of oxygen needed by the human body increases during morning exercise. With the deepening of breathing, harmful substances in the fog will be inhaled into the respiratory tract, thus endangering health.

You can do morning exercises after the sun comes out.

You can also switch to indoor sports.

Judging from the time when the sun comes out, the better time for outdoor sports in winter is 9 am.

Second, try to reduce going out.

In foggy weather, try to reduce going out.

If you have to go out, you'd better wear a mask.

For people with allergic asthma, wearing a mask is more important. Masks can prevent some allergens such as dust mites from entering the nasal cavity and play a certain protective role.

Third, patients insist on taking medicine.

Patients with respiratory diseases and patients with cardiovascular and cerebrovascular diseases should insist on taking medicine on time in foggy days to avoid getting sick; And strengthen self-monitoring, pay attention to the body's feelings and reactions, and seek medical advice in time if you feel unwell.

Fourth, drink more tung platycodon grandiflorum tea, tung ginseng tea, tung platycodon grandiflorum granules and arhat fruit tea.

These herbal teas can prevent and treat throat itching caused by inhaling dirty air in foggy days, and have a good lung moistening effect.

Especially in the afternoon, the effect is better.

Because the fog is thickest in the morning and almost disappears at noon, people inhale more dust and impurities in the morning, so they can clear their lungs in time when drinking in the afternoon.

Fifth, pay attention to regulating emotions.

People who are psychologically fragile and have psychological barriers will feel extremely heavy, nervous and depressed in this weather. Such people should pay attention to emotional adjustment in foggy days.

You can watch comedy TV series or listen to cross talk at home to cheer yourself up.

Don't close the window too tightly.

There will be kitchen fume pollution and furniture additive pollution at home. If there is no ventilation, dirty indoor air will also be harmful to health.

You can choose to open the window for a short time at noon with sufficient sunshine and less pollutants.

Seven, try to stay away from the road.

The concentration of pollutants is the highest when large cars enter the city during peak hours and at night.

Eight, calcium, vitamin D, eat more tofu, Sydney.

Fish and tofu are people's daily favorite foods. Fish is a kind of "intensive" nutrient, and tofu is both medicine and food, which can replenish qi and deficiency, and its calcium content is also quite high.

Vitamin D rich in fish has certain biological activity, which can increase the absorption rate of calcium by more than 20 times.

Stewed lily in Sydney can achieve the effect of moistening lung and resisting virus, and you can eat more in foggy days.

Protect the environment and prevent smog. Composition 350 words Fifth grade primary school

I am a sparrow.

I travel through the human world.

They say that human intelligence is the highest of all animals.

Higher animals are what humans call themselves.

In my opinion, human beings are obviously the stupidest animals on earth.

Look at that hillside, the barren land is so desolate without the embellishment of green grass and red flowers. The source of everything is the chemical plant on the top of the hillside.

Look at the thick black smoke from its chimney.

Is destroying the earth's ozone layer clothes.

I flew to the chemical plant.

I saw a similar one and flew over.

I saw it dying and said to me, "Go, this smoke is poisonous." I looked at it and flew away reluctantly.

I believe those stupid humans will be punished.

I looked at the chemical plant with hatred.

Unfortunately, I'm just a sparrow with little strength.

Several months have passed, and the chemical plant is still running, but human beings have paid the price for what they have done.

Look at the smog in that city.

Does the earth think that mankind has lost? Then release smog to remind people? Fortunately, people have realized their mistakes, and many people are protecting the environment.

But will the spilled water come again? Man can only pay for his actions. If human beings still do not know how to repent, then the day when the earth dies is also the time when human beings die.
