一阵疾风呼啸而过,“呼——呼——”,树枝摇曳着,叶子颤动着,惊动了鸟儿们独享的幽静。真是个可恶的天气,已记不起何时有这样的恶劣天气!我仰望天空不由自主的感叹道。

往常的街道早已不大一样了,没有了喧闹和繁荣,寥寥无几的行人,只见来来往往的车子匆匆而过,无聊极了。街道的东边景色倒是不大一样,人非常的多,可是却还有几丝凄凉:行人们各各是夹着衣服,紧皱眉头,沉默寡言。在商场门口,聚集的人十分得多,但大概十有八九是来避风的吧!唉声叹气地人也占大部分,他们明显正为外面的冷空气发愁呢!相反,一个人多,一个人少,却有着相同的凄凉。都是“冷”字惹得祸。

“真是的!原本的‘晚上散步计划’泡汤了,老天爷真不作美。”我再次抱怨道。原来,最近海内出现了大量的冷空气出没在沿海地区,使得温度急剧下降,把瑞安城变成了一座“冷城”。我又站在了窗头,呆呆地望着天空。

一场冷空气,带来许多不便,可又有谁能知何时才是个头?

保护空气英语作文怎么写【三】

我们常说空气是看不见、摸不着;看不见是真的,但摸不着是假的;我们能感受到风,而风就是流动的空气形成的,所以空气是摸得着的。空气并不是单一的一种气体,它是由氮气、氧气、二氧化碳等多种气体组成的。其中氮气占78%,氧气占21%、二氧化碳及其他气体共占1%。所有生物(除病毒外)都要进行呼吸,吸入的\'气体中真正有用的是氧气。那空气中的氧气岂不会多年后用完呢?不会的,因为植物可以吸收二氧化碳进行光合作用产生氧气。

空气中的氮气对生物没有直接作用,但它可以被闪电通过系列反应转化成氮肥,供植物使用。氮气性质不活泼可用来保鲜食品,医疗上可以用液态氮做麻醉剂。二氧化碳的用途也比较多,它可以制成干冰进行人工降雨、还可以用来灭火。空气中的稀有气体大多数可以充入灯管中制成霓虹灯,使夜晚色彩亮丽。

想要了解空气,就得了解大气层。大气层说白了就是地球上厚厚的一层空气。然而大气层并不是想象中那么简单,它分为好几层,每层高度不一样,海拔越高,空气越稀薄。所以卫星或其他航天器一般都会飞到几百千米以上,若飞得底了些,那稀薄的空气会使卫星减速、坠落。

之前说的都是看不见的,接下来会有看得见的。

这些看得见的东西就是空气中的微小颗粒,当然,它们不属于空气,它们只是夹杂在空气中而已。常见的灰尘就是微小颗粒,但灰尘在其中已是“大个头”了,比较小的有“PM10”“PM2。5”等。而“PM2。5”小到可以直接进入你的肺泡!所以也被称为“可吸入颗粒物”。众所周知,这些颗粒对人体是有害的,颗粒越小,在空气中停留的时间越长,对人体的危害也就越大。

了解了这么多后,请为了这生命的必须品多植一颗树,少乘一次车;以便以后还能再次深呼吸而不咳嗽吧!

保护空气英语作文怎么写【四】

Tiger is one of the most valueable animals to human beings today. It is somehow like a cat, but much bigger than it. It lives in the forest, and feeds on small animals.

Nowadays, the number of the wild tiger is becoming small and small. Maybe there will be no tiger any more if people continue cutting the trees, destorying the living environment or hunt the tiger just for the skin. We must stop all these mistakes. We should protect them, because the world without tiger is not a completed one.
