Today, we have a health class. The main content is the harm of haze.
We watched a movie called “the harm of haze”， which mainly explained how terrible haze is.
Haze passed through our bodies, just like games. It comes to the blood vessel first, let the partners block the blood vessel together, so our blood pressure will rise; it also has a partner who is less than 0.5cm and has a knife in both hands, and can directly pass through the blood vessel; it comes to the internal organs, which are like a tree, and there is white fat like a giant, which can directly eat the dirty things. However, we have iron ore in our body. If we eat too much white fat, we will die. This is a blood station! So the resistance of man has decreased. It's finally at the center - the heart, because we just blocked your blood vessels, so your heart will cause myocardial ischemia. “Tremble! Human beings! I'm in every breath of yours, ”cried haze.
Haze has a great influence on us. With haze, we can't play in the playground, can't have physical education class, and we need to wear a little annoying mask. Therefore, we should protect the environment and nature. As long as you start little by little, you will be able to achieve the results you want.
It is reported that thick fog and haze surround many parts of China. People have to wear masks when they go air pollution is getting increasingly worse,it has become the main concern of people.
Air pollution can have serious consequences for human’s health and also severely affects natural ecosystems. Millions of people die of illnesses related to air pollution every to particles from exhaust emissions,green house effects result in warmer weather,acid rains corrode the earth,and frequent haze causes traffic problems.
Confronted with such situation,positive measures should be adopted. The government should keep its regulatory role for properly supervision. Related rules should be made out for reducing emissions of new vehicles and limiting high-emission ories should meet standards for curbing emissions of pollutants in surrounding ， provinces and municipalities in each target region should set up a mechanism for the joint prevention and control of air pollution.
Dear Bill,
I’m glad to receive your letter,thank you for your caring for the weather and my I’d like to tell you something about the smog.
Since the winter last year,the smog has occurred a lot of has done great harm to our daily traffic accidents happened just because of the heavy smog weather,more and more people have to go to see the doctor because the serious disease caused by the smog,quite a lot of flights have to be put off,a great number of people have to stay at home for fear of the poisonous air caused by the smog.
People have realized the great harm caused by the smog and the importance of protecting the le all over the country are taking measures to reduce the smog government suggests people go to work or school with the public traffic, such as the bus and the we should plant more trees.
According to me, I will go to school by bike or on foot, and I won’t throw the waste addition, I will tell the people I meet to protect the environment as possible as they d you like to tell me some good ideas?i’m looking forward to your reply.
Yours,
Li Hua
Recently,haze weather has become a daily one right here in large part of le are forced to wear the mask to avoid breathing poisonous it is necessary to find out the reason why leads to that and work out the we trace the cause for haze weather ，the main points are as follows ，first,china 's air quality standards are rather lax and evaluation factors are limited,so you will see that current →←air appraisal system has nd,some people just go for economic interests instead of turning out products according to relevant law and tend to use obsolete equipment in which they are high likely to emit a great deal of wasted air.
Third,across our society ，relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for the haze weather
To settle this problem,a series of meaures should be taken as t ，we should strengthen air monitor to lower the levels of small particulate nd,we should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people 's daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze.
Third,we should develop green and energy-saving energy to lower the emission of haze and improve air far as i am concerned ，if we work together to be able to do such measures ，our environment will getting better and better and haze weather will vanish completely.
Haze is air pollution in which is mixed up with dust, smoke and other dry particles ，and it obscure the clarity of the sky and interacts with the natural environment.
This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust, and soot from wildfires. Manmade sources can include motor vehicles, and industrial fuel burning, and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.
Just go out, find day yellow, is wrong! Mother said; “It seems to be under the storm!”
Walk, feel the chest is very stuffy, look at things like float up, dizzy. The dirt and dust is in the sky, with a trace of fear. The sky is gray, the air is damp, give a person a kind of depressed feeling.
The next day on the language class, the teacher let us discuss the haze weather yesterday. Some students say it's caused by some farmers burn weeds, some classmates say environmental contamination caused by.。. As for me, I think should also be caused by environmental pollution. In the end, or a teacher for us to solve the mystery. It turns out that this kind of weather because of environmental pollution and farmers burn formed by the union of weeds, but the teacher say again: “farmers burn weeds are merely a catalyst, the main or we cause environmental pollution.” In addition, the teacher also adds some knowledge to us, let us say again that peace yesterday always have to differ? Just in the afternoon, I found some cars open headlight. XiaoYao found usually go to the bathroom in the morning you can see it don't need to turn on the light, and yesterday don't turn on the light does not see.。.
Fog haze let me know that this time must be to protect the environment!
剛出門，就發現天黃黃的，太不對勁了！媽媽説；“看來要下暴風雨嘍！”
走着走着，就感覺胸口很悶，看東西就像飄起來似的，頭暈暈的。天空中飄的不知是泥土還是灰塵，有一絲恐懼。天空灰暗，空氣潮濕，給人一種很壓抑的感覺。
第二天上語文課時，老師讓我們討論了一下昨天的霧霾天氣。有的同學説是一些農民燒雜草所引起的，有的同學説是環境被污染所造成的……我呢，覺得也應該是污染環境所造成的。最後，還是老師為我們解開了謎團。原來，這種天氣是因為污染環境和農民燒雜草結合形成的，但老師又説：“農民燒雜草只是一個催化劑而已，最主要的還是我們污染環境造成的。”另外，老師還向我們補充了一些知識，又讓我們説了説昨天和平常有什麼不同？我發現剛到下午，有些汽車就開大燈了。肖瑤發現平常早上上廁所不用開燈就能看見，而昨天不開燈就根本看不見……
這次霧霾讓我知道了一定要保護環境才行！
