同学们,这几天,我们议论最多的话题就是:雾霾。雾霾就像地球的不速之客,这段时间,总是出现在我们的周围,影响了我们的学习生活,还危害着人们的健康。
面对如此的天气,我们大家一定有很多的感受和体会。有位同学写下了这样的作文:回想起这几天雾霾天气,真可谓苦不堪言!记不清从哪天起,本该迎着灿烂的朝霞去上学的我,却是在浓浓的雾霾中摸索前进。连续几天过去了,天空依然雾霾重重,不见消散。
其实这种雾霾天气,不同于普通的大雾,雾是一种自然现象,是由浮游在空中的小水滴或冰晶组成的水汽凝结物。而霾就不一样了,又称灰霾(烟霞),主要是人为因素造成的,它是由空气中的灰尘、硫酸、硝酸等组成的小灰粒。雾霾天气对我们的身体,尤其是呼吸道系统有着严重的危害。雾霾天气的形成有多种原因,其中最重要的一点就是环境的污染。
那么如何保护环境,应对雾霾天气呢?首先我们一定要做到
