Foggy in the morning, I found that the outside, lianshan look not clear, the sun is hiding in bed lazily would not wake up, the visibility is very low. And turn on the TV, the news said in this matter, so this a few days in nanjing, anhui and other regions of schools have stopped because haze weather, hangzhou also let students stopped all outdoor activities, we also carry out a mask?
I ran to ask mom, it's strange, my mother told me: "when people talk of fog is actually composed of fog and haze of these two kinds of weather, looks like the dense fog fog weather, but in fact there is a big difference. The fog is formed by the ground water vapor condensation in the air, while haze because very small dust particles in the air, sand particles, virus particles such as evenly suspended in the air, they are intertwined haze weather. The weather is very large, the harm of human body if we inhalation of the bacteria, viruses, and it is easy to get sick, serious word will kill."
As far as I know, are made by automobile exhaust fog weather, air pollution emissions from factories and other secondary pollution, so we are now in addition to reducing the outdoors, drink water more, more should protect the environment, to take care of our home, let haze weather is far from us.
早上，我發現外面霧濛濛的，連山都看不清楚，太陽也懶洋洋地躲在被窩裏不肯起牀，能見度非常低。打開電視，新聞裏也都在說這個事情，原來這幾天南京，安徽等地區的學校都因爲霧霾天氣停了課，杭州也讓學生停止了所有的'戶外活動，大家外出還都帶上了口罩呢。
我很奇怪，就跑去問媽媽，媽媽告訴我：“通常人們說的霧霾實際上是由霧和霾這兩種天氣組成的，霧霾天氣看起來像起了大霧一樣，但實際上有很大的區別。大霧是由地面空氣中的水汽凝結形成的，而霾則是因爲空氣中極細微的灰塵顆粒，細沙顆粒，病毒顆粒等均勻地懸浮在空氣中，他們交織在一起就是霧霾天氣。這種天氣對人體的危害非常大，我們如果吸入了這些細菌，病毒，就很容易生病，嚴重的話還會致死。”
據我所知，霧霾天氣都是由汽車尾氣，工廠排放出的廢氣等二次污染造成的，所以我們現在除了要減少戶外活動，多喝開水之外，更應該保護環境，愛護我們的家園，讓霧霾天氣遠離我們。
