Write a composition with suspension as the main topic

Smog and our life

This winter, the smog weather has attracted everyone's attention, and it is harmful. Several cities have already taken its trick, so we should strengthen environmental management and stop letting smog weather run rampant.

many people must know the cause of smog. Of course, smog is composed of fog and haze. The main cause of fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the ground air, which is the product of water condensation in the air near the ground. Fog will mainly reduce visibility and cause traffic hazards, but it is not harmful to people.

Haze is composed of dust, sulfuric acid, nitric acid and other harmful substances in the air, which will make the atmosphere turbid, blur the vision and reduce the visibility, and will do great harm to the human body. In this way, two unrelated brothers, Fog and Haze, get together, causing unprecedented damage to the atmosphere. The air quality in some cities has reached the level of moderate pollution, and some cities have reached the level of heavy pollution, which is very terrible.

Haze is very harmful, which will affect roads, railways, aviation, power supply systems and crop growth. It is also easy to lead to the spread of infectious diseases and the occurrence of various diseases. Harm people's health. And it will lead to the difficult diffusion of pollutants in the air, enhance the toxicity of harmful substances, and seriously, it may also lead to toxic fog. And it will do great harm to people, especially to the respiratory system. It is reported that the number of people with respiratory diseases this winter has increased by% 3-%4 compared with last winter. What an amazing number this is, which deserves our deep thought. Therefore, it is urgent to prevent smog weather.

Our preventive measures should be in place, and we should stop doing morning exercises and outdoor sports in foggy weather. It's just not enough. I think the main reasons for this bad weather are the emission of automobile exhaust and industrial production exhaust. Therefore, the state should issue policies as soon as possible to manage and control the emission of harmful gases, plant more trees and grass, and purify our environment. I think, if everyone mobilizes, the foggy weather should run away in a despondent way.

In short, I hope everyone can take action, plant more grass and flowers, protect the environment and create a green and natural environment for our future generations. 2. Write a composition about 4 words on the theme of environmental protection

1. Writing about environmental protection

The phrase "everyone is responsible for protecting the environment" can be seen everywhere! It happened that someone didn't follow it.

On Tuesday morning, Yan Ziyi dropped a large roll of napkins into the water. Poor thing, a large roll of napkins was "sacrificed" like this.

Yan Ziyi picked up the napkin. I thought she was going to throw it into the trash can, but I didn't expect that she was so lazy. The trash can was just behind and she didn't want to walk over and throw it in. Unexpectedly, when we opened the window and threw it, a piece of white garbage floated into our contract area instantly. Alas! In a blink of an eye, there is another garbage in the contract area, and the students on duty in the contract area have to work hard again.

I just found out now that as long as I sit by the window, many people don't bother to throw garbage in the trash can. Just open the window and throw it away. No wonder our contract area was deducted 1.5 points on Thursday! This is really asking for it. Besides, every group of students will sit at the north window. According to this calculation, if the students at the north window throw three garbage a week, then after one semester, our contract area will not be called the contract area, but the garbage area.

If Mr. Zhong asks us to pick up garbage in the contract area again, the students will certainly complain again. It's easier to throw garbage than to pick it up! Therefore, it is everyone's responsibility to protect the environment, and not littering is convenient for you, me and him.

2. About 4 words of environmental protection composition

On the front of the trash can, there is a placard: "Pay attention to hygiene, love cleaning, and put garbage into the box." The scarlet letter on a white background is very eye-catching.

I held a dustpan full of garbage in one hand, and I was two steps away from the dustbin, so I went to the mouth of the box and slammed the dustpan down. With a bang, the dustpan was full of garbage, and more than half of it was scattered outside the box. I was just about to turn around and walk back when I stopped and looked at the placard: "Pay attention to hygiene, love cleaning, and put garbage into the box." I wanted to go back and pick up that pile of garbage, but I thought again, "why should I pick it up?" It's a waste of time, I have to go back and do my homework! " Then I turned and left.

a little brother stopped me after a few steps: "Brother, you spilled the garbage outside!" " "So what?" I disdained to ask. "Brother, the teacher told us before that we should take care of the environment, so you should pick up that pile of garbage!" My little brother insisted, but I didn't care about him: "I don't care about the environment!" I won't pick it up! " I said loudly, "You don't care about me!" My little brother was scared away by me, and I left triumphantly.

suddenly, I stopped and looked at the pile of rubbish. I feel that people around me are looking at me, so I dare not look up at others, only dare to look at the pile of garbage. I have been staring at that pile of garbage for a long time, and I don't know whether to pick it up or not. In my heart, it's like two people are fighting, one says to pick it up and the other says not to pick it up. I don't know what's going on. I'm very scared and scared. I am afraid that my parents will ignore me and my friends will ignore me. Thinking of this, I still picked up the pile of garbage.

at this moment, I am very happy, and my heart seems to be relieved. I don't have to worry about my parents leaving me alone; Don't worry about my friends ignoring me; Don't worry, everyone is watching me! Now that I think of that little brother, to be honest, I really appreciate him a little.

Only after today's incident did I understand what "stressing hygiene and loving cleanliness" means. Understand what "protecting the environment is everyone's responsibility"! 3. Write an 8-word composition < P > with no study and only sweeping the street as the main topic. He is very talented. We are having a good chat. This is my teacher. "When he saw that we all stopped talking, he asked us that Mr. Xu would come later and would not deduct points for our class. He has never been partial to any student: "What are you talking about? Don't make any noise. Tell me. No one cares about discipline and directly deduct the points of our class."

Teacher Xu is such a teacher. Teacher Xu came again. He saw us talking and we talked about the plot in the game.

that time when Mr. Xu sent the school road team. I didn't care. I should learn to relax. Every time we are criticized, we are convinced. "A humorous teacher must be a strict teacher. I think of a sentence that the math teacher said and understand why Mr. Xu deducted the points of our class. I chatted with my classmates in the road team, but this time I deducted the points of our class directly on the record table, which is a teacher who can be one with the students. He is fair again? " I only know which company made it, although my black hair is not long.

Mr Xu has a good relationship with us. He is my art teacher, Mr Xu. He was very happy after listening to it? Tell me about it. I think Mr. Xu is too unreasonable and so good. The teacher not only talked to us about learning problems, but also didn't know how to do it. I was very angry at that time, and at the same time I was strict. He told us in detail the scientific knowledge of three-dimensional film making and so on, and our class teacher went out again? It doesn't matter, I still talked to the students next to me: "Do you know how the cutscenes in that game were made? The eyes are bright, which reminds us to be quiet during the assembly. We all listen very seriously! " We told Mr. Xu the game we were talking about, and we started talking generously. Unexpectedly, the requirements for us are not relaxed at all, selfless, famous and fair teachers. A teacher who mingles with students must be an impartial teacher, thinking and asking. When we look at Mr. Xu, he often tells us some ancient poems: It doesn't matter, but every student who makes a mistake will definitely try to get the person who made the mistake to make up and correct it! I'm also interested. Later, I said.

Mr. Xu is tall and tidy, but he suddenly comes over and leaves school.

once, a health knowledge lecture was held. As long as we are interested, he is a talented person I know: "Is it a game chat?"! So, it happened that it was Mr. Xu's turn to be the teacher on duty that day. Only Mr. Xu came over every once in a while. < P > My best teacher has a teacher who will talk about it. 4. Write an essay on the theme of caring for the school and respecting the teacher. Requirements: 1. < P > The beautiful campus is our happy home and the place where we study and live every day. Its environmental sanitation has a direct impact on us. At the same time, school environmental sanitation is also an important symbol of civilization. Each of us should take the responsibility of protecting the environment of classes and schools. Seeing the campus, I sometimes throw waste paper around, which makes me feel very sad. To this end, I am determined to protect the campus environment, starting with me.

During this period, I often saw waste paper on the ground at school, so I took the initiative to pick it up and put it in my schoolbag. Today, the school showed a video about actively picking up paper. In the video, some students took the initiative to pick up the waste paper when they saw it, and some saw it but passed by the waste paper as if nothing had happened. This video made me feel that it is limited to protect the campus environment and sanitation by personal strength, so I want to appeal to the students loudly. From now on, let's take action for our beautiful campus! Let's do it together, without damaging a flower, a grass or a tree, without wasting a drop of water or electricity, without tearing, throwing, spitting or doodling. When you see waste paper, please take the initiative to bend down, pick it up and take it out of the campus, because we not only pick up garbage, but also pick up morality.

Students, a good campus environment needs to be created and maintained by you and me. For the sake of our beautiful campus, let's work hard together, and let's "show mercy and stay under our feet"! In order that we can study in a beautiful environment, please start from me, start from scratch, and create a beautiful and warm campus together. I believe that through everyone's efforts, our school will become more beautiful, cleaner and neater. 5. Write an essay about 8 words with safety as the main topic

Food is the most important thing for people, and food safety is a huge matter, which affects people's health and concerns people's lives.

The broadcast on TV and the report in the newspaper expose the jaw-dropping truth: the cup of bubble tea that made our mouth water was actually processed from an unsightly "underground factory"; That red jujube is actually a blue winter jujube soaked in the potion and changed color. Recently, the well-known "Sanlu milk powder", which has caused a nationwide uproar, has made people panic.

how do we believe that the food we eat every day is safe?

In primary school, I was always attracted by the fragrant barbecue, boneless chicken fillet and stinky tofu on the way to and from school. These dazzling foods made my mouth water for three days in thousands of feet, but I didn't know whether it was harmful to my health, so I had to flinch, swallow the saliva in my mouth and have to stay away from these temptations. But I really don't want to eat? Absolutely not. In the final analysis, it is the food safety that makes me doubt, so I am confused between "delicious" and "safe".

Just like the "Sanlu Milk Powder" incident, milk products of many dairy companies such as Yili and Mengniu were found to contain melamine, and the sales of dairy products in the market dropped sharply. People questioned the dairy products of major brands, and many newborn parents did not know which brand of milk powder to choose for their children!

it stands to reason that food safety is a matter of course. But now who can guarantee what food is safe? Food safety should not be to get away with it by reprinting the shelf life, make money without conscience, and take people's health as a bet!

Food safety has sounded the alarm again, and relevant departments should pay more attention to food safety. It is an urgent task for the relevant departments to strengthen food safety, improve the ability of food hygiene supervision and inspection, find hidden dangers in time and nip them in the bud!

where can I find safe food?

May junk food stay away from us, let healthy food accompany us and let food safety be found everywhere! 6. Write an essay on the theme of "rain"

Listen to the rain

When I was a child, I lived under a tile house. Whenever it rained, I could hear the intermittent and mournful sound of rain. When I grow up and live in a reinforced concrete forest, I can't hear the sound of rain. It seems that life lacks a lot of aura, something that can make people feel soft and weak, and my heart is slowly desertification.

so I miss the rain in the tile house.

Rain is weak, the lightest thing in the world, and it can't knock the heavy reinforced concrete building. Wawu, on the other hand, has raindrops on it, tinkling and immediately making a pleasant sound. People living in the hut also have the blessing of being close to nature in the rain. When the rain is sudden, the voice is generous and violent, like hundreds of horses singing together, like Ma Benteng. As the rain slows down, the sound becomes weaker, and it seeps into your heart gently, like the breeze in the ear in warm spring. The tiles seem to be specially set for the rain. They play dutifully, and the hearts of those who listen to the rain will overflow with endless affection.

people like to sit quietly and listen to the rain when their hearts are full of nostalgia and regret. Old people have the ambition of "lying in the middle of the night listening to the wind and rain, and the iron horse glacier dreams"; The dying beauty has the bitterness of "and as raindrops brighten yellow leaves, the lamp illumines my white head"; Acacia lovers have the longing that "the phoenix tree is drizzling, and it will drip at dusk"; Affectionate poets have the reverie that "a small building listens to the spring rain all night, and a deep alley sells apricot flowers in the Ming Dynasty".

Rain has become an emissary for people to decorate their feelings and place their wishes.

In my spare time, I was lucky enough to return to the place where I used to listen to the rain. It happened to be a light rain that day, and I heard this familiar and unfamiliar rain. In the mist, there is a strange emotional appeal in the rain, which has not been communicated for a long time. It keeps me away and shows me that it is strange to me, but I can feel the breath of its existence from the deepest part of my consciousness. I have a carefree feeling of waking up from a dream and a sense of vicissitudes after being confused.

oh, what I met in the rain was my self who had separated from time and space. It was telling me everything before. I hesitated. I asked myself: Who am I? Still the old me?

There is a saying: "Young people listen to the rain songs upstairs, and the red candle is faint. In the prime of life, listening to the rain in the boat, the river is wide and the clouds are low, and the broken geese are called the west wind. " Different life circumstances make people feel different when listening to the rain. However, listening to the rain is all about listening to the dialogue of the soul, listening to the rushing of the true feelings and listening to the flowing of the years. Apart from the echoes of the years, the sound of the rain has also brought about the regret of the past and the melancholy of wanting to talk again. It seems that only in the light rain of this tile house can the soul breathe and life continue.

The sound of rain is still ringing, just like my real heartbeat. 7. About 5 words of composition with saving as the main topic are urgently needed

In China's cities, especially large and medium-sized cities, the shortage of water resources is also an embarrassing problem faced by people. China's per capita water resources is only a quarter of the world average, but its water consumption is huge. Like Beijing, the per capita water consumption is four times the world average. Therefore, don't think that saving water has nothing to do with you, a drop.
