These days, mist haze is too serious, the mist haze that is dusky everyday is enveloping a sky.
这几天，雾霾太严重了，每天都是灰蒙蒙的雾霾笼罩着天空。
The mist haze that mom gives me to had told Beijing, Heibei is more serious, high speed road is very much seal rose. Hey! Why is it Chinese capital? I feel to call Chinese “ haze ” is about the same still.
妈妈给我讲过北京、河北的雾霾更严重，高速路很多都封起来了。哎！为什么它是中国首都呀？我觉得叫中国“霾都”还差不多。
Is mist haze how form? When PM2. 5 exceed atmosphere circular ability and bear the weight of degree, appear extremely easily large-scale mist haze. PM2. 5 what be? PM2. 5 it is the diameter in pointing to atmosphere be less than or be equal to 2. The grain content of 5 micron, it contains a large number of poisonous and harmful material, to human body health and quality of condition of big compression ring are having serious effect.
雾霾是如何形成的呢？当PM2。5超过大气循环能力和承载度，极易出现大范围的雾霾。PM2。5又是什么呢？PM2。5是指大气中直径小于或等于2。5微米的颗粒物，它含有大量有毒有害物质，对人体健康和大气环境质量有着严重的影响。
Is mist haze how to invade what human body destroys health? That makes me fine dilatancy comes.
雾霾是如何侵入人体并破坏健康的呢？那就让我细细说来。
PM2. ” is having the 5 “ brother with it a “ is entered close game ” , and this enters the health that involves game to endangering the mankind directly.
PM2。5和它的“兄弟们”正进行着一项“闯关游戏”，而这项闯关游戏直接危害着人类的健康。
The first close: Nostril. After they enter nostril, the “ brother ” of above of about 20 micron writes a composition / in this be killed in battle; The 2nd close: Guttural. The gift that this passes to have above of about 10 micron only is met “ dies ” , but PM2. 5 their bodies are lightsome, very good however through. The 3rd close: Alveolar, they fight with leucocyte, lymphocyte all the way, human pulmonary alveolus has 300 million many, once they hold off pulmonary alveolus, the mankind is suffocative come.
第一关：鼻孔。它们进入鼻孔以后，大约20微米以上的“兄弟”都作文/在这阵亡；第二关：咽喉。这一关只有大约10微米以上的才会“离世”，但PM2。5它们身体轻盈，却很好通过。第三关：肺泡，它们一路和白细胞、淋巴细胞作战，人类的肺泡有3亿多个，它们一旦挡住肺泡，人类就喘不过气来。
And, noticed! They have diameter of ”—— of “ advanced batman to be less than 0. 5 micron, can enter blood-vessel directly, should have more “ only advanced batman ” , can let hemal narrow, blood pressure is elevatory, cause thrombus; And can launch attack to ” of human “ core, because this causes cardiac muscle to lack blood, loss, rhythm of the heart is disorder, the harm that causes haze of mist of heart stalk …… is real too terrible!
并且，注意了！它们有“高级小兵”——直径小于0。5微米，可以直接进入血管，只要有更多“高级小兵”，就会让血管变窄，血压升高，引发血栓；而且会向人类“核心”发起进攻，因此引发心肌缺血、损伤，心律紊乱，引发心梗……雾霾的危害实在太可怕了！
Actually, we breathe every, mist haze commits murder in “ ” .
其实，我们每口呼吸，雾霾都在“杀人”。
If we each person can be made from oneself, little drive, green goes out row; A variety of trees, protective forest …… believes we can see future every day green water of blue sky white cloud, green hill.
如果我们每一个人都能从自身做起，少开车，绿色出行；多种树，保护森林……相信未来我们就能天天看到蓝天白云、青山绿水了。
