    近期，雾霾天气频频发生，越来越严重，也引起了全国人民的注意和关照。中国不少地方把雾霾作为灾害性天气预报。
    雾霾是怎样形成的呢?请听我慢慢道来。它是由pm2.5尘粒、烟粒、盐粒等均匀地浮在空中从而形成霾。不过，雾和霾还有本质上的区别。起雾时空气潮湿，出现霾时空气干燥，并且对人体有害无益，长期吸入会导致死亡。
    雾霾又是怎样产生的呢?汽车尾气，工业生产排放废气，和鞭炮等都是雾霾的主要来由。少开一次车，少放一次鞭炮。让我们中国人不要再忽视环保。
    不过，相对的自我保护也是要有的。为了避免吸入雾霾，雾霾天气切勿开窗。出去旅游，或者游玩时，请戴上口罩。多喝桐橘梗茶,并且适量补充维生素d。还要多喝水，饮食要清淡。

    保护环境吧!让这几年的雾霾天气逐渐减少吧!让人们不用因此而死亡!
    雾霾形成的主要原因篇二:《雾霾围城缘何由》阅读答案
    雾霾围城缘何由
    霾的成因是多方面的。天气分析表明，北方城市冬季凡是大范围、长时间、高浓度的雾霾，总是由气候背景、天气条件、城市环境、社会管理等多种因素叠加所致。
    从气候背景来看，需要空气湿度长期在高位徘徊并趋于饱和，以便为雾霾的产生提供充足的水汽资源。从天气条件来看，需要近地面空气静止少动，无风，大气层结稳定，不利于污染物的流动与扩散，而有助于水汽、悬浮颗粒物的逐渐累积。从城市环境来看，由于城市高楼林立，楼宇间距过窄，阻碍了空气流动;机动车数量猛增，烧烤等活动造成不容忽视的低空污染。此外，环境保护步伐没能跟上等，这些都成为引发雾霾的强劲推手。从社会管理来看，煤烟型城市每年工业和采暖期用煤量惊人，采取集中供热模式，同一时间开启。后两个因素为雾霾大规模发生与持续发展提供了更多的凝结核。因此，清晨生成的辐射雾与徘徊不去的烟霾相互叠加，正是“不霾则已、一霾惊人”的原因所在。
