Haze sixth grade composition

In our daily life, when it comes to composition, everyone is certainly familiar with it. Through composition, we can gather scattered thoughts together. Do you know how to write a good composition? The following is the composition of smog grade six that I collected and sorted out. Welcome everyone to learn from and refer to. I hope it helps you.

Smog sixth-grade composition 1 "Cough ... Cough ... Cough ..." Cough sounds come and go in the classroom. Why do so many people catch cold? It turns out that according to the statistics of the meteorological department, there were 19 foggy days in Ningbo recently, and the blue sky and white clouds disappeared, and the sky was gray.

I stood on the balcony window and looked around. The tall building is soaked in milk. On the highway, we drove and couldn't see anything in front of us.

Haze is an aggregate of a large number of particulate dust, smoke particles or salt particles suspended in the air. A weather phenomenon that clouds the air and reduces horizontal visibility. Haze contains a lot of harmful gases and inhalable tiny particles. Haze seriously affects human health, from rhinitis to bronchitis. Being in this environment for a long time can also induce pneumonia. Our city of Ningbo is already very crowded, and the arrival of "smog" has made urban traffic safety worse. There are so many cars scraped on the road that they have become parking lots and can't move.

How is the hateful smog formed? There are three reasons: first, the tall buildings in the city block the wind and can't blow away the smog. The second is the phenomenon of upside down. There seems to be a pot cover in the sky, so I can't get out. Thirdly, the exhaust gas from factories and automobiles greatly increases the suspended particles.

For our health, the school cancelled all our outdoor activities. Some schools even postponed the sports meeting. Haze when will you leave our beautiful and lovely Ningbo city?

I miss the blue sky and white clouds! I miss fresh air! I miss the happy time of playing outdoors!

Good evening, audience friends. The weather in Beijing is fine today, and it will be foggy tomorrow. Please try to reduce travel and keep warm. Ok, audience, today's weather forecast is over. Thank you for watching. I will see you tomorrow. "Oh, how to smog every day! I'm so bored that I can't even go to physical education class. I have to wear a mask every day. Really! " I said angrily. At this time, my mother came over and said, "Who told you to pollute the air often?" "We polluted the air? Where are we going to pollute the air? " "You use your brain melon to think about it? You didn't shoot during the Chinese New Year! " "Chinese New Year? That was a few years ago! " "The harmful substances in that gun also pollute the air!" "Did I mention that the harmful substances in the gun won't pollute the air?" "What are you arguing about? What's so noisy? It's just smog! What about you? " Dad came to dissuade me from going to war with my mother. Dad began to reason: "it's really easy to say that you want a blue sky, but it's really difficult to say it." First of all, you have to change the habit of shooting in the new year. Mom is right. " Mother felt that she had the upper hand: "Hear it! I am right. " "Words can't say that, the toxic gas produced by your company also pollutes the air, so we should protect the environment. Protecting the environment is everyone's responsibility! "

Students, I believe that through our efforts, we will certainly usher in the blue sky of the motherland.

The 3rd century AD was a period of highly developed science and technology. In this bright era, mankind got rid of cold and hunger and lived a happy life. It can be seen that technology has brought great changes to our lives. But, you know what? On our beautiful earth, there is a terrible "big devil", whose character is surly and grumpy, which has caused great harm to the environment; People are "scared", and they always have to wear "armor" before they dare to go out. Yes, it's terrible-smog!

The foggy weather, extremely low visibility and gloomy sky make people feel depressed. The sky seems to be shrouded in gray smoke. It is very uncomfortable for people to walk on the foggy road, covering their mouths. Although they wear thick masks, they still feel a layer of dust on their faces, which is very harmful to their health. So, I had a whim and wanted to design a multifunctional mask to get people out of the smog.

First, put a small flashlight in front of the ordinary mask to illuminate the front; Then carefully remove the fiber cotton from the mask, install a special mini air purifier, and put a small button next to the mask to connect the air purifier with the flashlight. Just press the button gently, the purifier will start working and the flashlight will turn on. The purifier inhales the smog in front of you first, and then converts it into fresh air, so that people can breathe normally.

This kind of mask is easy to carry and use. Just charge the air purifier and flashlight every night. Fully charged for 48 hours!

Although the current technology can't make my design come true, I believe that my idea will come true one day in the future.

The haze weather is very serious recently. Originally, I had to run and exercise every morning during the big class from Monday to Friday. Because of the foggy weather, the daily running practice has also been cancelled. In foggy days, many pedestrians on the street wear masks, fearing that smog will be sucked into the lungs and affect their health. When can China get rid of environmental pollution and smog?

It is foolish to develop economy and destroy the environment at the same time. The earth is everyone's home. If the earth's environment is seriously damaged and the ecological balance is broken, then people's homes will no longer exist. Haze is also a manifestation of serious environmental pollution. Haze is very harmful to people's health. Many experts say that smog is more harmful to people than SARS. Haze directly harms the human respiratory system, especially the lungs. Secondly, smog will also hurt people's hearts. Studies have shown that particulate pollutants in smog weather may lead to human myocardial infarction. Thirdly, smog weather hurts people's skin. The skin is exposed to the outside, which is the first place to contact with smog, and it is also the place that has been exposed to smog for the longest time. Therefore, it is more important to clean the skin in foggy days. Finally, smog can also harm our brains. When there is haze in PM2. 5 Increase 10 μ g/m3, and human brain function will age for three years. This study also gives us a better understanding of the harm caused by smog.

In foggy days, protective measures must be taken to reduce outdoor activities. Try to bring a mask that can prevent smog particles when you go out. The most fundamental way to solve smog should be for everyone to protect and care for the environment. If we continue to destroy the environment, the smog will be more serious in the future, and people may not be able to live on the earth. Let's take good care of our home earth!

On Sunday, with the help of my father, I checked the air quality in Xi in early March online. After the inspection, I was surprised. I found that there were 6 days of heavy pollution, 2 days of light pollution and 7 days of moderate pollution in China.

It turns out that we live in such an environment. I asked my father, "Are smog and dust harmful to human body?" My father and I looked up the information on the Internet. It turns out that smog and dust are very harmful. Haze will lead to the spread of infectious diseases and the occurrence of various diseases, which will bring great harm to human health. Dust will also endanger people's health and bring great inconvenience to human travel.

I also checked the causes of smog and dust. It turns out that the air pressure in the atmosphere is low and stagnant air is the main factor. Stagnant air is the tiny particles in the air that gather together and float in the air. Due to the large dust on the ground and low temperature, people and vehicles on the ground are stirred up by dust ... Dust is a harmful weather phenomenon caused by the interaction of wind, rain and sand, and its formation is inextricably linked with global greenhouse effect, vegetation destruction, species extinction and climate anomaly. He is also divided into sandstorm, floating dust and strong dust. ...

I don't think we should exploit natural resources without restraint and cut down trees at will. People with cars should drive as little as possible, take more buses, ride more bicycles and travel green. Try to use energy-saving lamps for light bulbs, turn on less air conditioning, and everyone should sprinkle more water on the street. Don't litter everywhere, plant more trees to protect our earth.

Teacher's comment: The biggest advantage of this exercise is that the cohesion of the article is natural, and some sentences connecting the preceding with the following are used better. Unfortunately, the sentence in the last natural paragraph of the composition is not fluent enough to be integrated with the whole article. It may be better if we can talk about what we should do from the causes of smog and dust.

Now, in China. A very terrible devil is coming. When there are more and more cars in the city and fewer trees outside the city, he becomes stronger and stronger. Finally, he broke free from the bottle that bound him and rushed to the place where we lived, which immediately enveloped the whole city. The devil's name is smoke!

Even in the daytime, people are surrounded by smog, and the air is gray and can't be seen clearly. Children stay at home, wear masks even when they go out, and turn on all the lights even at school. Many children are sick of it.

People shouted at the smog: "Smog, go back!" You devil, we don't need you! "

Haze laughed after listening: "In fact, I was invited back by you! If you hadn't driven cars to emit exhaust gas every day and opened so many factories in the suburbs to emit exhaust gas, I would have strengthened my strength and cut down my most powerful enemy trees and vegetation. I won't be so strong, I'm actually your guest! "

The sun came out, and he couldn't penetrate the thick smog to bring people sunshine.

The sun looked at the thick smog and thought for a long time. Finally, the method of subduing smog was realized.

Sunshine shouted to people: "since smog is afraid of trees, plant all kinds of trees quickly;" Since the power of smog comes from automobile exhaust, drive less! Since the smog comes from our polluted environment, let's change the environment! "

Finally, one day, the smog became weaker and weaker and became endless.

Sunshine finally meets everyone again. When everyone is happy to celebrate with the sunshine. Sunshine warning: "Don't be too happy. We should cherish the environment of the earth now. You know, the devil of smog may come back at any time! "

On this day, my classmates and I went out to line up as usual to prepare for the big recess activities. Suddenly a broadcast sounded: A notice was broadcast below: There is smog today, and there will be a big recess in the classroom. Please be sure to tell each other. Play the announcement again ...

Hearing this, some students complained repeatedly, some lamented, and some said, alas, when will the weather be good? I can't help looking out of the window. I saw it was gray, as if it had been enchanted by the devil. Dark clouds are gathering and foggy. All the houses and trees in the distance are shrouded in smoke. People can't help feeling bored and depressed. They want to hold their breath. I can't help but get lost in thought ... Now the whole world is getting warmer, polar regions are getting less and less, and green homes have become cement valleys. I only saw white fog once when I was a child, but now it is polluted into smog. In such an air environment, people are particularly prone to get sick. I remember the day before yesterday, my good playmate cousin suffered from allergic asthma. When I first heard the news, I was shocked. How can a healthy child get this disease? My mother told me that more and more children are suffering from this disease because the air environment is getting worse. I really hope that more and more people can pay attention to environmental protection. I hope those so-called modern factories will stop discharging waste gas into the air, discharging sewage into rivers and cutting down trees. There are blue sky and white clouds everywhere, green trees and red flowers, birds are singing happily on the high branches, and flowers are blooming and fragrant in the embrace of Mother Earth.

I hope that day will come soon, when everything is so fresh and beautiful. Let's protect the environment together

What's wrong with the weather? How did it get so dark? 15 It's already 7 o'clock. It's still so dark. Unlike the weather before. The sun used to shine at 7 o'clock, but now it is still so dark even at 8 o'clock. This is the devil we created ourselves-smog.

Smog has now become a frequent visitor in China. Come to China for a while every morning and noon. This is all done by some "black-hearted" bosses, and hundreds of millions of people in China are shortening our lives and making us die faster because of this hateful smog. It's all done by those black-hearted bosses. Nowadays, there are many "black-hearted" bosses in the world. In order to make more money, they emit waste smoke to our mothers and spread smog to the earth's atmosphere.

Did you do all this? In order to make more dirty money, you withered our tree. Because of you, what is our mother earth like now? We live in smog every day. It's really uncomfortable to see our compatriots breathing harmful gases every day!

I suggest those black-hearted bosses close the factory! Don't hurt our motherland to make money, we should repay our motherland, not bite the hand that feeds you. Give the birds a beautiful sky. Return a beautiful motherland to mankind.
