导语:随着人们生活水平的提高,私家车数量不断增加。下面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!

Private cars have become an important aspect of people‘s life in many parts of our country, especially in large cities such as Beijing, Shanghai and Guangzhou. While they bring much convenience to people, they are also widely criticized. There are some arguments for owning private cars. In the first place, cars allow people to move around freely, which greatly improves our living standard. We can easily drive cars for sightseeing on weekends. In the second place, cars are a comfortable way to travel, especially in bad weather. Last but not least, the car industry can boost economy by creating many job opportunities in production of steel, rubber, glass and so on. However, there are also many good arguments against cars. First of all, they pollute the environment by emitting harmful gases and giving out loud noises. In addition, cars cause a large number of traffic accidents, which bring great misery to the victims‘ families. As far as I am concerned, we should limit the number of private cars by providing better mass transportation and better service for the people. Everyone should sacrifice his or her own interest for the common good of the society.

【参考译文】

私家车已成为我国许多地区人民生活的一个重要方面,特别是在北京、上海和中国等大城市。虽然他们给人们带来很多方便,但他们也被广泛批评。有一些理由拥有私家车。首先,汽车可以让人们自由走动,这大大提高了我们的生活水平。周末我们可以很容易地开车观光。其次,汽车是一种舒适的旅行方式,尤其是在恶劣的天气里。最后但并非最不重要的是,汽车工业可以通过创造钢铁、橡胶、玻璃等的就业机会来提振经济。然而,也有许多好论据反对汽车。首先,他们通过排放有害气体和发出大声的噪音来污染环境。此外,汽车造成了大量的交通事故,给遇难者家属带来了极大的痛苦。就我而言,我们应该通过提供更好的大众运输和更好的服务来限制私家车的数量。为了社会的共同利益,每个人都应该牺牲自己的利益。

篇1:关于雾与霾的作文

当云落到地上,便会变成雨,倘若不落地,则便是了。最近总是“满地云”,可却非雾非雨,倒却是雾的同胞兄弟——

雾与霾,虽说同胞,长得确乎几分相似,甚至还有词叫作雾霾的,但是两者的区别还是蛮大的。说起雾,人们也许会联想到“雾都”伦敦。雾是悬浮于空中且接近于地面的细微的水滴组成的一个庞大的群体,也可以说是飘在地上的云了。雾虽然会降低能见度,但它通常只出现在清晨,太阳一照基本就消逝了。只要人们不长期处在浓雾中,它一般不会向人痛下毒手,反倒给人一种雾蒙蒙的飘逸舒畅的感觉。但它的弟弟却不怎么温和,动起刀子来是杠杠的。它与哥哥不同构成中除了一部分水汽,还有大量的PM2。5,说白了就是飘在空中的浓浓的灰尘。它可以在一天中的任何时候出现,对人们产生相当大的危害。由于其部分烟尘颗粒可进入人的肺部,可以引起呼吸系统、循环系统的诸多疾病,且由于能见度低在交通方面也扼杀了许多无辜的生灵。就说刚刚提到过的雾都伦敦吧,1952年12月5日开始,伦敦连续数日空气寂静无风。当时伦敦冬季多使用燃煤采暖,市区内还分布有许多以煤为主要能源的火力发电站。由于逆温层的作用,煤炭燃烧产生的二氧化碳、一氧化碳、二氧化硫、粉尘等气体与污染物在城市上空蓄积,引发了连续数日的雾霾天气,据史料记载,从12月5日到12月8日的4天里,伦敦市死亡人数达4000人。而在12月9日之后,由于天气变化,毒雾逐渐消散,但在此之后两个月内,有近8000人因为烟雾事件而死于呼吸系统疾病。足见霾的杀伤力之强。

雾与霾都是自然现象,但在霾的成因中,却又有很大一部分缘自人类自身。霾的形成与污染物的排放密切相关,城市中机动车尾气以及其它烟尘排放源排出粒径在微米级的细小颗粒物,停留在大气中,当逆温、静风等不利于扩散的天气出现时,就会形成霾。

最近国内大气污染比较严重,人们也颇受了其苦。解决方法呢也倒是有的。治理雾霾最主要的方法是减少排放。在这点上,人类可以控制工厂的废气排放。减少能源的使用是不现实的,而清洁能源远不能满足需求,且价格昂贵。人类能做的,就是尽快制造出更节约资源的机器。还有,当然是植树造林了。

霾,并不可怕,它只是在雾里掺了灰罢了,倘若人们能够同心合力,从小事做起,从自己做起。相信在我们的努力下,天,还会蓝,视野,还会清晰,满地的乌云终会变成满地白色的清纯的水雾,或是万里晴空。

鞭炮隆隆,不知不觉大街上已经荡然无存,归心似箭的游子们,带着老婆孩子,和一年用难以表达的苦赚来的钱,在一度清风中骑着摩托回家了。身处昆山,即清静了许多,可是不知疲倦的依然辛勤的工作着,一层白雾笼罩着红色春地,不以让人失去一丝丝情调,但鞭炮声也不停的铺满了过年的氛围,震响天宇,但是2015年的地球,似乎并不乐意聆听这喜气洋洋的炮声。

2013至2014年,雾霾的身影席卷而来,不时白雾漫天,不时呼吸困难。新春来临之际,鞭炮的引燃必不可少,但现在空气质量就像漏斗一年比一年差,也许你常常在浏览器上看见:今天的空气质量为严重污染,儿童老人不可停留于室外。那么,人们为何还要将鞭炮烟花点燃呢?一旦点燃,空气将会二次污染,全国的排量,将会影响空气!影响呼吸!影响儿童的未来!

保护环境这句话也许已经让人听得厌烦,但是这是人类生存的必备条件,和在地球上生活的资格。放鞭炮也是过年的代表性的活动。那么,又该说到怎么预防,一切切都是我,你,他所有人的“功劳”,汽车尾气、工业排放、建筑扬尘、垃圾焚烧,如果我,你不丢掉在手上刚用完的卫生纸,不丢刚吃完热腾腾红薯的塑料袋,但我和你还是没扔向绿色的垃圾桶,让它们躺在了马路。也许你和我要去离家半公里的超市,但我们都选择了坐小轿车,汽车的排放,又一次抹脏了透明的空气。作为小学生,也许建筑不会经常来我们家做客,但我们可以选择实用的,对于自己刚好的,不接近奢华,如果我们要求不高,建筑工们也没必要建造鳞次栉比的高楼大厦……一切一切都只要我们每一个人,包括老师,教授,领导,明星,甚至习近平,李克强,所有人都应该做好地球给予我们的使命!

虽然放爆竹影响了空气质量,可是爆竹是中华民族的独特的民族风俗,放爆竹弘扬中华民族的传统习俗,也增添了世界文化大花园的活力,我们应该不仅用前所未有的韧劲和毅力,心无旁骛,还要用永不妥协的生命力去美化环境,还要去保护好中华民族的独特习俗,不过量排放!

雾霾中的鞭炮,你可以选择污染环境,也可以保护环境以及保护风俗,雾霾影响着我们,刻不容缓的需要我们去保护,空气质量需要提高,雾霾来袭,也是地球危险的警告!现在,收起你正在丢失垃圾的手,扔进垃圾桶,地球将会变绿,everybody将会向你微笑!

保护环境,不说为了别人,就说为了自己吧,让自己的未来充满希望!

Today we stay at home and not go to class. Do you know why? By the way, it is just because of the fog.

Haze? Nanjing and other places of dust is overmuch, combined with the dust and fog, becomes the haze, inhaled into people get lung disease, asthma and other respiratory diseases.

Recently, pm2.5 is close to the extraordinary, in nanjing today at 3 o clock in the morning, pm2.5 has reached 466 micrograms of a cubic meters, entered the serious pollution, pm2.5 is one of the "culprit" haze weather. Not just the pm2.5 exceeds bid badly, pm10 has recently started to crazy, 3 a.m. yesterday, pm10 has reached 579 micrograms of a cubic meters, the nanjing the worst pollution index was about to break! In addition, the sky appeared a "mock sun"! Is too much because floats in the sky. If nanjing on October 1, the sky is blue, so today in nanjing will be gray and a piece of the sky.

Fog not only have an effect on the human body, many planes, ships, cars and so on all cant normal travel. Nanjing lukou airport has 53 flights affected by haze on time boot. Many highways have been closed, the highest visibility on the streets of only 10 meters the following, the car travel is very inconvenient. Hundreds of ships to stay in the Yangtze river in zhenjiang. The influence of the fogs really big ah!

We air pollution index of the middle and lower reaches of the Yangtze river has been more than the north, like tianjin, Beijing, hebei and other provinces, cities have been we left behind. The factory in the north is more, to produce a lot of dust, according to the reason for the northern cities should air pollution is the most "powerful", can be in November to December Chinas worst air index, almost all is our "occupy" in jiangsu province.

Now that the fog is so terrible, we should also consider what to do! 1, when faced with heavy fog, the first thing to hide the fog haze. Haze days dont go out as far as possible, dont get up early to exercise more. 2, mask is fog out of necessity. Will always wearing surgical masks, but not always wearing a mask, only on the road, a lot of bacteria such as hospital, pm2.5 wear a lot of place, at other times, try to put in my pocket.

This is the fog haze, a great influence on our body, we must learn to prevent it! That is why our school classes.

今天我们同学都留在家里不去上课。你们知道为什么吗?对了,就是因为霾。

雾霾是什么呢?南京等地的灰尘过多,而雾跟这些灰尘相结合,就变成了霾,人大量吸入会得肺病、哮喘等呼吸道疾病。

最近,南京的pm2.5接近爆表,到了今天凌晨3点,pm2.5已经达到了466微克一立方米,进入了严重污染,pm2.5是雾霾天气的“罪魁祸首”之一。不仅仅是pm2.5超标严重,pm10最近也开始疯狂起来,昨天凌晨3点,pm10已经达到了579微克一立方米,这项指标就快要破南京最差污染了!而且,天上还出现了一个“幻日”!就是因为天空中的漂浮物过多而形成的。如果说10月1日的南京的天空是湛蓝的,那么今天南京的天空将是灰蒙蒙地一片。

不仅雾霾对人体有影响,许多飞机、船只、汽车等都不能正常出行。南京禄口机场已有53个航班受雾霾影响不能准点开机。许多条高速公路都已经关闭,街头的最高能见度才仅仅10米即以下,这让汽车出行非常不方便。数百只船只停留在长江镇江段。雾霾的影响可真大呀!

我们长江中下游的空气污染指数已经超过了北方,像天津、北京、河北等省、市都已经被我们落在后面。北方的工厂较多,会排出很多的灰尘,按道理来讲北方城市应该空气污染是最“强”的,可11月到12月中国的空气最差指数,几乎全部是我们江苏“占领”的。

既然雾霾这么可怕,我们也应该想想该怎么办吧!1、当遇到浓雾天气,首先要躲雾霾。雾霾天尽量不要出门,更不要早起锻炼。2、口罩是雾天外出的必需品。要常带口罩,但不能常戴口罩,只有在马路上、医院里等病菌很多,pm2.5很多的地方戴,其他时候,尽量放在口袋里。

这就是雾霾,对我们人体影响很大,我们要学会预防它哦!这也就是我们学校为什么停课的原因了。

这几天,天总是灰蒙蒙的,见不得阳光,明天出门妈妈都要让我戴口罩,说有空气太脏。什么是霾呢?爸爸给了我答案: 霾又称大气棕色云,在中国气象局《地面气象观测规范》中,霾天气定义:“大量极细微的干尘粒等均匀地浮游在空中,使水平能见度小于10千米的空气普遍有混浊现象,使远处光亮物微带黄、红色,使黑暗物微带蓝色。”据研究,目前在我国存在着4个霾天气比较严重地区:黄淮海地区、长江河谷、四川盆地和珠江三角洲。

霾与雾有什么区别? 一般来讲,雾和霾的区别主要在于水分含量的大小:水分含量达到90%以上的叫雾,水分含量低于80%的叫霾。80%——90%之间的,是雾和霾的混合物。霾和雾有一些肉眼看得见的“不一样”:雾的颜色是乳白色、青白色,霾则是黄色、橙灰色;雾的边界很清晰,过了“雾区”可能就是晴空万里,但是霾则与周围环境边界不明显,城市化和工业化是霾产生的主要因素。 霾分:轻度霾、中度霾和重度霾。 一:轻度霾:空气相对湿度小于等于80%,能见度大于5公里且小于10公里;二:中度霾:空气相对湿度小于等于80%,能见度大于2公里且小于等于5公里;三:重度霾:空气相对湿度小于等于80%,且能见度小于等于2公里。

爸爸还说霾是由于人们过度追求享受,而忽视了大自然的承受能力而产生的不自然的天气现象。妈妈赶紧加了一句话:咱家决定不买车,出门就骑自行车。低碳出行我光荣。

导语:霾问题是人们追求利润而造成的,人们曾经对环境所做的现在已经得到了报复。现在人们已经意识到了大自然的报复是多么的大,保护环境是主要的任务。下面是yuwenmi小编为大家整理的英语作文,欢迎阅读与借鉴,谢谢!

Since the development of the technology, the society gets modernized, people make use of the high technology to pursue more profit. Though the government has noticed the problem that people do to the environment, they still can’t prevent negative result that the polluted environment brings.

Many years ago, the most prominent problem of the polluted environment is that the river and the water were changed their color, some fish even died for the polluted river. Now the situation becomes ever worse, lately, in the big city, like Beijing and Shanghai, people are annoyed by the bad weather. It is not the rainy day, but the haze around the sky, there is no way for people to run away for it. The haze contains toxic elements, people breathe it and hurt their bodies.

The haze problem is the result of people’s pursuit for the profit, what people did to the environment now has been paid back by the environment. Now people have realized the revenge from the nature is so huge, protecting the environment is the main task. No matter how bad the environment is, people still need to do something to fix their mistake.

【参考翻译】

打从科技的发展,社会已经变得现代化,人们充分利用高科技来追求更多的利润。虽然政府已经注意到了人们对环境所做的事情这个问题,但是他们仍然不能阻止被污染环境的所带来的后果。

很多年前,环境污染所带来的最突出问题时河流和水的颜色被改变,一些鱼甚至死于被污染的河流。现在这样的情形变得更加的糟糕,最近,在大城市,比如北京和上海,人们受困于糟糕的天气。并不是因为雨天,而是因为雾霾包围天空,人们无处可逃。雾霾中含有有毒的元素,人们呼吸着雾霾,损害着他们的身体。

雾霾问题是人们追求利润而造成的,人们曾经对环境所做的现在已经得到了报复。现在人们已经意识到了大自然的报复是多么的大,保护环境是主要的任务。无论环境变得多坏,人们仍然要去做一些事情来弥补自己的错误。

碧海蓝天是我们的梦想,在这个到处是的城市里,我们对蓝天的渴望显得更为迫切。

记得上周末妈妈带我去上兴趣班,一路上,我们的整辆汽车都沉浸在雾霾当中,双眼好似被一双轻纱掩盖着,外面的景物若隐若现。一开始,妈妈以为是车的挡风玻璃起雾了,打开暖气,想方设法让这些雾散走,可将近开了10分钟,雾仍然没散开。后来,我们才恍然大悟,挡风玻璃上已经没雾了,现在的雾是在空气里的。妈妈望着这样的天空,说:“哎,现在的雾霾严重到了这种程度,以后的人们该怎么生活?我们人类一定要想出对策来制服雾霾。”听了妈妈的这番话,我心里萌生了一个新念头,过几天不就是植树节吗?而且下午不正好有空吗?

上完课,我们直达花鸟市场花买了三株小树苗,接着就来到小区的荒地上开始植树。我们一家人开始动手了,前提是每人完成一株。我拿起铁锹使出了喝奶的劲去挖坑,可是地上的泥土很顽固,老跟我作对,怎么都不肯放手离开大地妈妈的怀抱。旁边的爸爸告诉我可以用脚来帮忙出力。于是我按照爸爸所说的,用脚去踩住铁锹,果然泥土就投降了。坑挖好了,我再看看旁边的妈妈,动作比我慢多了,我心里一阵窃喜。紧接着,我立马拿过树苗,插了进去,一放手,咚,掉了!看来一个人的力量太小了,老爸又来帮忙了,他扶着小树苗,我不停地挥动着铁锹把土埋上,此时又用上刚才老爸教的那招,让脚来帮忙,这样土会埋得更严实。手脚并用,看来成效真不错。

仔细瞧瞧自己亲手栽种的树,越看越喜欢,忍不住笑了。同时爸爸妈妈的成果也都完工了。我望着眼前的三株小树苗,表情有点变了,妈妈纳闷地问我怎么了?我不高兴地说:“这片荒地上就这三株可怜的树苗,对环境的绿化起得了作用吗?”妈妈摸着我的头,说:“傻孩子,天底下像你这样的有心人多的是,不信下次你再来看,这一片将会是一片绿海,而且你平时可以节约更多的零花钱来种树,我们并不是要在植树节才要植树。多多植树,肯定能把雾霾这大魔鬼给赶走的!”

听了妈妈的一番话,我松了一口气,立马又有一个新的想法跳出脑海。今天我不单单自己种树,还要去呼吁身边的小伙伴一起来种树,用它们的热心肠换一份新鲜的空气,让人类居住的家园不再被雾霾所困扰!

篇10:大气污染小学生空气污染

全文共 1394 字

空气污染是空气中某些物质的含量超过正常含量时,形成危害动、植物,影响其生存的现象。大气中C0、NH3、SO2、H2S、Cl2、03和N02等物质的正常含量均在百万分之一以下,对动、植物没有明显的不良影响。但19世纪以来,由于工业和交通运输的发展,那些物质大量排入大气,使空气污染日趋严重,影响到动、植物生命活动乃至人体健康。

污染物的来源,有的来自自然界(如火山喷出的烟灰),有的来自人类活动,其中工业、交通运输产生的废气是主要的污染源。空气污染可分为气体污染物和气溶胶状污染物两大类。气体污染物包括SO2,、03,、氮的氧化物以及碳氢化合物等;气溶胶污染物包括固体粒子(粉尘、烟尘气)和液体粒子(烟雾、雾气)两类。直接向空气中排放的污染物质,叫一次污染物。空气与污染物之间相互作用,产生反应,或空气中光化学反应引起的污染物变质所产生的新污染物,叫二次染物。

空气污染物种类很多,其中对农业威胁较大的约有十多种,如SO2、 HF、C12和光化学烟雾等。 气象条件对空气污染物的影响,水平风速和对流层高度是影响大气稀释空气污染物能力的两个气象要素。当农田上空主导风向来自污染源时,农田容易受有害气体的危害;风力强弱则影响空气污染物的扩散速度、污染物在空气中的浓度与平均风速成反比;通常午后湍流强,空气处于不稳定状态时,有利于扩散。夜间晴朗无风,近地面逆温层可使污染物在地面上停滞积聚,加剧空气污染的程度。另外,在准静止的高气压系统中,由于下沉逆温阻止下层排放的污染物扩散到大气上层,可形成近几百米厚的污染层。各国多次发生的严重空气污染事件大都是在低逆温层、风速小和无雨的气象条件出现几天之后形成的。

空气中一些污染物例,如SO2和悬浮于空气中的农药颗粒等,经雨水淋溶落到地面,又可污染土壤和植株。污染物对植物的危害,一般是通过气孔进入植物组织,干扰酶的作用,阻碍代谢机能,有的有毒物质在体内还可进一步分解或参与合成过程,产生新的有害物质,侵害细胞组织,抑制光合作用,使生长受阻、产量降低、品质变劣。其危害分为急性、慢性和不可见危害等。高浓度污染物造成急性伤害,引起产量显著下降,低浓度污染物,在长时间作用下,造成慢性危害,一般症状不明显。不可见危害只造成生理上的障碍,一般没有症状。

植物受空气污染危害的程度,主要受下列因素影响:污染物浓度和植物接触它的时间;植物本身的构造和所处的发育期以及环境条件的影响。如充足的光照,适宜的温度、良好的供水和空气湿润,较高的C02浓度等,都能导致叶片气孔开放,易受污染危害。 植物对大气的净化功能。不少植物具有一种以酶作催化剂的潜在解毒力,能够分解一些有毒物质,或形成一些大分子络合物,暂时可以降低毒性。1公顷森林,每年可吸滞灰尘30多吨,1公顷柳杉林,每年可吸收700多公斤S02,柑桔树的叶子可吸收储存硫达1%,青杨和桑树具有较强的吸收铅尘的能力,加拿大杨、银杏、榆树、梧桐、桉树等都是较好的“天然吸尘器”。草坪的吸附粉尘能力比裸露地面大几十倍。因此环境科学的任务之一,是要充分发挥植物净化大气的作用。选择吸收污染能力强的植物,扩大造林绿化面积,根据污染源位置、污染物汇集区的地形地势、风向和污染气体的季节分配,统一考虑构成一种包围式或隔离式的林带,使含尘气流在移动中途被树林吸收。另方面要研究采取控制或减少排放污染物的措施,以保证大气质量符合规定的标准。

早晨起来,一出门:啊!好大的啊!天灰蒙蒙的,好像走进了朦胧的世界。妈妈拿出口罩叫我赶紧戴上,"戴口罩,多麻烦,多憋气啊!我不带,我不带......"妈妈语重心长的说:"这么重的雾天气,不带可不行,你会吸进有毒的空气"。我只好不情愿地戴上。上学路上妈妈给我讲了很多关于雾霾的知识:

一年来,我们固安经常出现雾霾天,空气严重污染。可是,出门戴一个口罩是多么不方便的事啊!原来,这雾霾是我们人类自己造成的,像汽车排放出来的尾气,烟花那重重的味道,都是造成雾霾天气的因素之一。听了妈妈的话,我意识到,应该呼吁大家一起保护环境,爱护地球!让大家都意识到自己的错误,应该共同携起手来,把雾霾天气赶走,创造一个美好的明天。

我想我们应该少开车,多坐公交车;可以不放或少放烟花爆竹;还可以多种一些植物;可以少开工厂,使工厂少排放废气等等。总而言之,我们就应该绿色环保,低碳生活。

为了我们每天都能呼吸到新鲜空气,并拥有蓝天、白云。我要大声呼吁:从身边的小事做起,从我做起,保护环境,刻不容缓!

Oliver Twist one of the most famous works of Charles Dickens is a novel reflecting the tragic fact of the life in Britain in 18th century.

The author who himself was born in a poor family wrote this novel in his twenties with a view to reveal the ugly masks of those cruel criminals and to expose the horror and violence hidden underneath the narrow and dirty streets in London.

The hero of this novel was Oliver Twist an orphan who was thrown into a world full of poverty and crime. He suffered enormous pain such as hunger thirst beating and abuse. While reading the tragic experiences of the little Oliver I was shocked by his sufferings. I felt for the poor boy but at the same time I detested the evil Fagin and the brutal Bill. To my relief as was written in all the best stories the goodness eventually conquered devil and Oliver lived a happy life in the end. One of the plots that attracted me most is that after the theft little Oliver was allowed to recover in the kind care of Mrs. Maylie and Rose and began a new life. He went for walks with them or Rose read to him and he worked hard at his lessons. He felt as if he had left behind forever the world of crime and hardship and poverty.

How can such a little boy who had already suffered oppressive affliction remain pure in body and mind? The reason is the nature of goodness. I think it is the most important information implied in the novel by Dickens—he believed that goodness could conquer every difficulty. Although I dont think goodness is omnipotent yet I do believe that those who are kind-hearted live more happily than those who are evil-minded.

For me the nature of goodness is one of the most necessary character for a person. Goodness is to humans what water is to fish. He who is without goodness is an utterly worthless person. On the contrary as the famous saying goes The fragrance always stays in the hand that gives the rose he who is with goodness undoubtedly is a happy and useful person. People receiving his help are grateful to him and he also gets gratified from what he has done and thus he can do good to both the people he has helped and himself.

To my disappointment nowadays some people seem to doubt the existence of the goodness in humanity. They look down on peoples honesty and kindness thinking it foolish of people to be warm-hearted. As a result they show no sympathy to those who are in trouble and seldom offer to help others. On the other hand they attach importance to money and benefit. In their opinion money is the only real object while emotions and morality are nihility. If they cannot get profit from showing theirkindness they draw back when others are faced with trouble and even hit a man when he is down. They are one of the sorts that I really detest.

Francis Bacon said in his essay Goodness of all virtues and dignities of the mind is the greatest being the character of the Deity and without it man is a busy mischievous wretched thing no better than a kind of vermin.

That is to say a person without goodness is destined to lose everything. Therefore I a kind person want to tell thosevermin-to-beto learn from the kind Oliver and regain the nature of goodness.

篇14:关于雾霾的作文600字

近几天如同一块灰色的幕布笼罩了,整个杭州城,她散布在大街小巷,看似很美,但他并不是李清照笔下的“薄浓云愁永昼,瑞脑消金兽中。”的雾,而是霾。

看似雾与霾十分相似,其实他们大有不同,雾是由水蒸气遇冷形成的小液滴汇聚而成的,然而霾则是由一些小微粒构成的。

雾霾有很大的危害,例如,吸入人体呼吸道后,会对人体有害,长期吸入甚至会至人死亡。那么,如何免于受它的危害呢?显然要从根源上解决雾。那么雾霾,又是如何形成的呢?是一些人类对空气造成的污染形成的。

雾霾的形成主要是由于汽车尾气,工厂排放的废气与冬季取暖排放的污染物。这都是因为人类自己的行为造成的,但可笑的是,这些行为反而损害的正是我们自己的利益。不过这也说明了一点雾霾的治理,要靠我们自己。面对于雾霾,我们应当做什么呢?其实我们只需要做一些微小的举动就可以改变现状。可是,我们并没有这么做。

那么,反观其他的事情像霾这样被人类创造出来的危害,真的少吗?并不是这样的。

许多像雾霾一样,笼罩在社会上空的灾害并不少见。只是正如我们把霾当成无害的雾一样,我们把这些还未显现的灾害当成了一种正常的现象,当成了没有危害的。但真的没有危害吗?正如被当成雾的霾,依然有霾一样的破坏力,这些被我们当做无害的潜在的危险,也具有极大的破坏力。

那么我们应该怎么做呢?其实我们要做的非常简单,只要我们从小事做起,做好日常的一些小事,就可以了。

愿笼罩在天空中,弥漫在街道里的雾霾,早日消散。

今天早晨,大弥漫,世界白茫茫的一片。人们穿着棉袄、戴着口罩,小心翼翼地行走着。建筑物在很远的地方若隐若现。窗户上也起了一层白白的水雾,就像冬爷爷悄悄为窗子送上了一幅洁白了窗纱,我用手指在“窗纱”上随意地画着画。

树叶在大雾的笼罩下绿中带着一丝白,像一个个在云朵里飞舞的小天使。大雾看似轻曼,柔和,但这只是它掩盖自己邪恶的面纱。听妈妈说,大雾中有对人体有害的物质,在大雾中出门,一定要戴上口罩。它能遮挡视线,阻挡为人们出行,引发交通事故。

但我仍然喜欢雾,因为雾像白茫茫的雪,让我想起了打雪仗、堆雪人的欢乐;雾像白白的围巾,让我想起了那温暖的感觉;雾像洁白的画纸,我可以在上面画出美丽的图画。

的作文400字(一)

雾霾是雾和霾的组合词,雾霾现象常见于城市。中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报,统称为雾霾天气。

我的家乡——唐山,也受到了严重的雾霾影响,使空气质量大大下降,人们患病率大大上升,特别是对呼吸系统的影响,使人们容易患上感冒等疾病,对心脑血管也有损伤。

雾霾的严重程度已经在一定程度上影响到了我们的正常生活,同一个城市的不同区域也有不同程度的污染。我曾经和妈妈坐车从我家香木林出发一直往东行,长宁道上天空晴朗,河西路上就开始出现雾气,走到钢窑路上就看到前方雾蒙蒙的一片。长期生活在这样的环境中谁也受不了,我巴不得快点离开这儿。

现在人们已经真切感受到了环保的重要性,正积极治理环境问题;不乱扔垃圾,少开车,植树护绿,关闭了重污染工厂等等。我想在我们的共同努力下,几年后的家乡一定是变得空气清新甜润,到处绿树成荫,鲜花盛开,每天都阳光明媚,天空湛蓝而深远,人们欢声笑语,快乐健康的生活。

雾霾的作文400字(二)

早上,我发现外面雾蒙蒙的,连山都看不清楚,太阳也懒洋洋地躲在被窝里不肯起床,能见度非常低。打开电视,新闻里也都在说这个事情,原来这几天南京,安徽等地区的学校都因为雾霾天气停了课,杭州也让学生停止了所有的户外活动,大家外出还都带上了口罩呢。

我很奇怪,就跑去问妈妈,妈妈告诉我:“通常人们说的雾霾实际上是由雾和霾这两种天气组成的,雾霾天气看起来像起了大雾一样,但实际上有很大的区别。()大雾是由地面空气中的水汽凝结形成的,而霾则是因为空气中极细微的灰尘颗粒,细沙颗粒,病毒颗粒等均匀地悬浮在空气中,他们交织在一起就是雾霾天气。这种天气对人体的危害非常大,我们如果吸入了这些细菌,病毒,就很容易生病,严重的话还会致死。”

据我所知,雾霾天气都是由汽车尾气,工厂排放出的废气等二次污染造成的,所以我们现在除了要减少户外活动,多喝开水之外,更应该保护环境,爱护我们的家园,让雾霾天气远离我们。

雾霾的作文400字(三)

一场可怕的浓雾在不知不觉中悄然而至。往外看,只能观察到白茫茫的一片,大街上浓雾弥漫,学校也应此停了课。本来美好的一天,就因为这鬼天气而变得单调。四周只剩下一片白灰色,当开车时,人们已无法看清前面的路况,仿佛走进了伸手不见五指的迷魂洞。车主们大都打开了双向灯,凭借着感觉开车,但很多汽车都出了事故。人们都不再出门,外出的人们也都纷纷带上了口罩。因为这鬼天气不但影响视线,对人体也有害,据说会使人体呼吸系统防御功能降低及呼吸不畅通、胸闷、干咳和咽干痒等,它的危害比"二手烟"有过之而无不及,而且严重的可能会使人死亡。

然而,我们不妨想一想,是什么让我们本来健康的变得那么危险呢?是那工厂排放的滚滚黑烟,是那马路上一日比一日多的汽车排放出的尾气,是那燃放的烟花爆竹产生的烟雾,还是那秸杆燃烧后的漫天浓烟……环境之所以会变成这样,都是因为人们自己产下的苦果。若是人们能够不再污染环境,我们的家园也不会遭受伤害,我们的人身安全也不会受到威胁。

此时此刻,我真心希望:人们能够从此事中觉醒,不再做伤害自己的事。让我们为干净的家园出一份力吧!

今天一走出加强班的大门,瞬间被眼前这幅景象惊呆了。

一片白茫茫,看东西仿佛里看花。我和杜其为了逃避雾的袭击赶紧往家里跑。路上看不见任何东西,视线不超过3米。大街上汽车都是一步一步往前蹭着,还有的车到了小区门口不知道拐。有的车更是到路口了不知道该往哪拐。行人有的不把雾霾放眼里,干脆不带任何防备措施,有的只是戴了一层口罩。

许多人认为雾就是霾,只不过换了一种新字,其实这样的理解是大错特错。雾是空气湿度太大而造成的,看起来就像云一样,对人体没有任何伤害。而霾就不同了,霾是空气中大量废气与有害物质组成的。霾中含有二氧化疏,硫酸,硝酸等有害物质,长期吸入会造成肺病,甚至会造成肺癌。

防范雾霾就是关闭门窗,不常去外面走动。尽管去外面走动也要戴上口罩。戴口罩也是有讲究的,普通挡风用的口罩起不到一点作用,必须要专业的防霾口罩或医用口罩。防霾口罩就是专门阻挡雾霾中的有害颗粒的,如PM2。5。而医用口罩,你如果仔细看,会发现有一些小洞洞,而这些洞洞可以拦截住细菌,累计在后面的薄纱上面,但是也有弊端,就是只能用一次,以免细菌滋生。而雾霾口罩就显得比较好了,以为不是一次性的,用完清洗一下,还是可以再用的。

今天大家懂了这么多知识,今后遇到雾霾天气可就不会那么可怕了,预防雾霾,保证健康。

英语作文汽车环境污染二

Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.
