雾霾的危害英语作文【优秀20篇】

雾霾，是我们常见的天气，有雾霾时，我们常常会带上口罩，这是我们的出行变得很不方便，并且还会对我们人的身体造成危害，那我们应该怎样预防呢？雾霾又是怎样形成的呢？我见到的雾霾是怎样的呢？让我们来看一下吧！

有一次，雾霾很大，华润建的居民楼中心路上的那一排大家一定都知道，而且很高。在那么大的雾霾下，连那么明显的建筑物都看不到了，可想而知，雾霾的影响有多大了。

而且，我们开车的时候，雾霾会影响我们的视力，常常会看不见导致撞车，有时候也会看不清红绿灯。雾霾还会导致飞机停机……等等麻烦。

雾霾其实就是天空中的粉尘颗粒组成的，差不多就是小型沙尘暴了，而且像这样的天气很常见。

之所以会这样，就是我们现在的化工厂太多了，人们不注意环保，对森林乱砍乱伐，往河里排放污水小学生作文作文人网你也可以投稿，汽车尾气……等，为什么化工厂这么多呢？因为人类的需求太高，只好这样。

我们应该多种树，减少工业排放量，少开车，多为环保着想，把一些不环保的商品排除，减少生活需求，这样，雾霾就不会再出现了。

雾霾，从2017年慢慢的来到了2017年新的鸡年。雾霾已经导致了多人生病，现在人们嘴里常常说出的雾霾，其实就是pm2.5。雾霾是人们健康的杀手，已经影响到了我国四分之一的国土，约有六亿人遭受雾霾袭击。

雾霾的形成，已经影响到了许许多多的人。专家说‘雾霾的形成是由空气中的灰尘、硫酸、硝酸、有机碳氢化合物等大量细小的细菌等形成了霾。’因为现在到了冬天，天气比较潮湿所以霾一受到潮湿的天气就会形成雾，所以经常被人们称为“雾霾”。

雾霾里面有许许多多人们留下的痕迹，汽车尾气、化工厂排气、化工厂排污水等……

人们在这个世界上给后代留下的够多了，可是现在的大家给后代却留下了一个十分不好的一种气体那就是我们现在的雾霾。

我们大家现在要一起联合在一起，一起抵抗病毒的新的援军——雾霾大将。我们可以多种树，少开车。我们每次出门的时候也要带上口罩哟!我们也尽量少出门。

雾霾也影响着我们的心情，开车时一定要注意前方的安全，不要疲倦驾驶因为雾霾也会让人们感到疲倦。如果遇到不好的事情，要控制好自己的心情，不要暴躁，要心平气和的去解决。

在交通方面，不要急躁，因为有霾，就会有雾，所以会容易堵车和发生交通事故。

所以请大家，一起防护雾霾吧!一起行动起来。

我们大家也要一起多运动，有雾霾的时候尽量不要出门，如果没有急事不要出门。我们也能可以在室内里面做一些小运动。

我们大家一起保护地球，保护我们的家园吧!

读完了，雾霾的危害你看到了吗？

[雾霾危害作文500字

以前，宜昌的空气清新甜润，楼下都有小花、小草、蜜蜂、蝴蝶和麻雀等一些小动物会来玩。

可是，现在宜昌的空气已经被严重污染了，雾霾灰蒙蒙的，像一条灰色的巨龙盘旋天空。雾霾之害，每个人都难以逃避。每个人都生活在雾霾里，无法拒绝、无法逃避由细颗粒物组成的雾霾天气，每天与雾霾“亲密接触”，肺就成了环境的吸尘器。对人体健康的危害甚至比沙尘暴更大。雾霾不仅危害健康，还影响了人们的正常生活，老人不能去晨练了，渡船要停摆了，高速公路要封路了。

雾霾背后隐藏着发展方式、产业结构、消费观念、生活习惯等一系列深层次问题，治理雾霾具有复杂性、艰巨性。欧美国家治理雾霾天气用了半个世纪，中国至少需要20年。公众既要有足够的耐心，也要对雾霾治理有相当的信心，只要齐心协力、对症下药，才能早日迎来蓝天白云的那天。市民可尽量少开车，污染容易治理难，政府应减少公务用车，加快城市公用交通建设，减少高污染项目的引进。

让我们共同行动起来，从我做起，为保护宜昌的空气环境贡献自己的一份力量。这样，宜昌会变得比以前更美，空气也会变得比以前清新甜润的!

今天，在电视里看到新闻播报北京等许多城市出现“雾霾”天气，行人纷纷都戴口罩出门……于是好奇的问爸爸：“雾霾是传染病吗?”爸爸说：“你可以自己上网查呀，哪样更详细的知道。”于是，我打开电脑，百度“雾霾”才知道它原来也是一种危害。

“雾霾”原来是由于空气中气压低，不流通，许多颗粒飘浮，地面上许多飘扬起来灰尘和汽车的尾气，工厂里生产或是家里取暖产生烟雾之类共同造成的。“雾霾”里的颗粒会对人体的呼吸道产生严重影响，比如咳嗽、咳痰、气喘、气管炎等等，再严重的会导致死亡。多么可怕呀!我连忙接着往下看看有什么办法对付，网上介绍说，早晨尽量不出门，出门要戴口罩，多吃清肺润肺的食物，比如：胖大海茶饮、川贝炖红梨之类的。

如此大的“害虫”原来也是人类自身无限制的开采与破坏环境造成，多么希望我们生活的环境是蓝天碧水，四季如画呀!请还地球一片绿吧!

雾和霾从气象角度来讲是两种不同的天气现象，雾的主要特点是近地面层，它的高度大概不超过400米，是在这以下的气层里面的微小水滴组成的。雾的存在会降低空气透明度，使能见度恶化，如果目标物的水平能见度降低到1000米以内，就将悬浮在近地面空气中的水汽凝结(或凝华)物的天气现象称为雾(Fog)，而将目标物的水平能见度在1000-10000米的这种现象称为轻雾或霭(Mist)。形成雾时大气湿度应该是饱和的，就其物理本质而言，雾与云都是空气中水汽凝结的产物，所以雾升高离开地面就成为云，而云降低到地面或云移动到高山时就称其为雾。一般雾的厚度比较小，常见的辐射雾的厚度大约从几十米到一至两百米左右。雾和云一样，与晴空区之间有明显的边界，雾滴浓度分布不均匀，而且雾滴的直径比较大，从几微米到100微米，平均直径大约在10-20微米左右，肉眼可以看到空中飘浮的雾滴。由于液态水或冰晶组成的雾散射的光与波长关系不大，因而雾看起来呈乳白色或青白色。

霾主要成分是一种灰尘，通常所说的尘埃，比如硫酸、硝酸这样一些微小的颗粒物。霾的厚度比较厚，可达1-3公里左右。霾与雾的区别在于发生霾时相对湿度不大，而雾中的相对湿度是饱和的。一般相对湿度小于80%时的大气混浊视野模糊导致的能见度恶化是霾造成的，相对湿度大于90%时的大气混浊视野模糊导致的能见度恶化是雾造成的，相对湿度介于80-90%之间时的大气混浊视野模糊导致的能见度恶化是霾和雾的混合物共同造成的，但其主要成分是霾。霾与雾、云不一样，与晴空区之间没有明显的边界，霾粒子的分布比较均匀，而且灰霾粒子的直径比较小，从0.001微米到10微米，平均直径大约在1-2微米左右，肉眼看不到空中飘浮的颗粒物。由于灰尘、硫酸、硝酸等粒子组成的霾，其散射波长较长的光比较多，因而霾看起来呈黄色或橙灰色。

随着空气质量的恶化，阴霾现象出现增多，危害加重，因此，我国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报，统称为“雾霾天气”。

雾霾对人体会产生什么样的危害呢?

(1)雾霾的危害主要在于一旦被人从呼吸道吸入，就会沉积于人的肺泡，沉积肺泡的烟尘被溶解后进入血液，容易造成血液中毒。

(2)未被溶解的部分被细胞吸收容易破坏细胞造成尘肺。

(3)霾中所含有的其他有害物质如二氧化硫主要是刺激人的呼吸道，对人的危害更大。

(4)雾霾严重时，其内的污染物杂质可使人的中枢神经发生病变，引起肺水肿或慢性气管炎，特别是当人们吸入肺部，严重时可导致肺气肿及肺癌等症。

(5)霾中的化学烟雾，当浓度达到某一界限后，就会对人的眼睛、呼吸道产生危害。霾中的一氧化碳，当其浓度为900PPm时，人接触1小时就会感到头痛、眼睛呆滞;当浓度达到1200PPm时，人接触1小时就会神经麻痹，有生命危险。霾中的碳氧化物，对人的眼、鼻和呼吸道有强烈的刺激作用，在一定条件下，将对肝、胃和心脏血管系统的功能产生破坏作用。

(6)雾霾天还会影响人的情绪，因为整天天气都处于阴霾沉沉，太阳昏黄阴暗，人体中的松果体会分泌出较多的松果体素，使得甲状腺素、肾上腺素的浓度相对降低。甲状腺素、肾上腺素等是唤起细胞工作的激素，一旦减少，细胞就会“偷懒”，变得极不活跃，人也就会显得无精打采。

人们需要采取哪些有效防护措施呢?

(1)减少出门是自我保护最有效的办法，尤其是有心脑血管、呼吸系统疾病的人群，更要尽量少出门。必须外出时记着戴口罩，不要开启车窗，减少对呼吸道的污染。

(2)可以暂时减少晨练，尽量选择在10—14时外出。同时，要多喝水，少吸烟并远离“二手烟”，减轻肺、肝等器官的负担。

(3)雾霾天必须外出，回到室内后要做到：洗脸最好用温水，可以将附着在皮肤上的阴霾颗粒有效清洁干净;漱口清除附着在口腔的脏东西;最关键的是清理鼻腔。

(4)在大雾天气升级的情况下尽量不要开窗;确实需要开窗透气的话，开窗时应尽量避开早晚雾霾高峰时段，可以将窗户打开一条缝通风，不让风直接吹进来，通风时间每次以半小时至一小时为宜。

Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.

Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.

Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.

In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day

Advantages and Disadvantages Of the Internet

I think it is not all bad for millde school student to search the Internet.Some students play games on line.I dont agree it at all.It has nothing to do with their study.And it will make them lose the interests of learning.But also it is very nessary for us to search the Internet.In the modern world,using computer and the Internet is an important skill.We can use it to find some information that we need and communicate with our friends,teachers and parents.Sending e-mail and check out some international news are useful for us as well.

Why this years winter always gray, the sky is white MCE blocked by air? "My father told me that the winter of this year because of the bad air quality formed a typical" haze weather." Haze weather "because many tiny floating in the air even the naked eye cant see the small particles, to our daily life and travel caused serious problems. In order to reduce air pollution and improve air quality, reduce the fog haze, let us start from oneself, starts from the Spring Festival, with practical action to promote green environmental protection idea, put a bunch of whip less, less pollution, less a piece of haze, to add a bit blue sky, let us happy life under the blue sky white clouds. Here, I issued initiative, the Spring Festival this year, lets do one" abandoned ", dont set off firecrackers, away from the haze, have the green years.

Haze weather we how to prevent this?

A, dont come out activities in the home, tell the old man, will know how to protect their children.

In haze weather, reduce travel, travel time to wear a mask, to avoid the small particles in the air in the lungs.

Third, in haze weather, dont open the window ventilation at home.

Haze weather, we not only should be "blowout", but also can "attack" :

One, in the Spring Festival, first of all, I do not set off firecrackers, and discourage their relatives and friends dont smoke, dont set off firecrackers.

Second, green travel, as far as possible with the bike instead of walking, use less cars, emit no exhaust and dont blow up the road dust.

Third, save electricity, save energy and chemical plant to improve the processing ability of emissions.

More than four, planting green plants, to purify the environment.

为什么今年的冬天总是灰蒙蒙的一片，天空被白乎乎的空气遮挡住?”爸爸告诉我，今年的冬天因为空气质量不好，形成了典型的“雾霾天气”。“雾霾天气”是因为空气中漂浮着很多细小的连肉眼都看不清的小颗粒而造成的，给我们的日常生活和出行造成严重困扰。为了减少空气污染，提高空气质量，减少雾霾，让我们从自己做起，从这个春节做起，用实际行动来倡导绿色环保理念，少放一串鞭，少一点污染，少一片雾霾，给天空增添一抹蓝，让我们在蓝天白云下幸福生活。在此，我发出倡议，今年春节，我们来做一回“弃炮族”，不放鞭炮，远离雾霾，过个环保年。

雾霾天气我们该如何预防呢?

一、在家不要出来活动，告诉老人、小孩要懂得保护自己。

二、在雾霾天气里，减少出行，出行的时候要带上口罩，避免将空气中的微小颗粒吸入肺中。

三、在雾霾天气里，在家不要开窗换气。

雾霾天气里，我们不但要会“防”，还要能“攻”：

一、新春佳节里，首先我要做到不放鞭炮，并且劝阻亲朋好友不吸烟、不放鞭炮。

二、尽量绿色出行，用自行车代步，少用汽车，不排放尾气，不吹起公路灰尘。

三、节约用电，节约能源，化工厂要提高排放废气的处理能力。

四、多种植绿色植物，净化环境。

Haze is air pollution in which is mixed up with dust, smoke and other dry particles ,and it obscure the clarity of the sky and interacts with the natural environment.

阴霾是空气污染和灰尘,烟雾和其他干燥粒子,它掩盖了清晰的天空,与自然环境进行交互。

雾霾原因This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust, and soot from wildfires. Manmade sources can include motor vehicles, and industrial fuel burning, and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.

这种空气污染物来自各种自然和人为来源。天然来源可以包括风沙、烟尘从森林大火。人为来源可以包括机动车辆、工业燃料燃烧和制造业务。触动了烟雾的主要原因之一是制造业务。许多工厂测量产生的烟雾对标准和烟雾严重影响空气成为空气污染。

雾霾危害The components that make up haze may have negative effect on peoples health especially that of the children and the elderly. Also not excluded are those who have certain diseases such as asthma, allergy, and pneumonia and lung disease. Workers working in the open air have a high risk in their health.

组件构成烟雾可能对人们的健康有负面影响特别是儿童和老人。也不排除是某些疾病如哮喘、过敏、肺炎和肺部疾病。工人工作在露天有很高的风险在他们的健康。

解决方法 One of effective solutions to help eliminate haze is to make some chemistry changes during the manufacturing process,so it could reduce harmful emissions which are produced by manufacturing operations

一个有效的解决方案,帮助消除烟雾是让一些化学变化在制造过程中,所以它能减少有害排放产生的制造业务。

Ten years ago, the Internet was practically unheard of by most people. Today, the Internet is one of the most powerful tools throughout the world. The Internet is a collection of various services and resources. According to Russ Brock, a director and consultant at the Center for Innovation and Inquiry, the Internet’s main components are E-mail and the World Wide Web. “There’s a lot more to the Internet than E-mail, search engines, celerity web sites, up-to-the-second sports scores, and chat rooms full of risqué discussions. The Net also ranks as one of today’s best business tools - if it’s used adroitly”. Almost all households contain the Internet; however, before people connect to the Internet, they need to be aware of its disadvantages and advantages.

十年前，对于大部分人来说网络都是几乎没听说过的。今天，互联网在整个世界中是最强大的工具之一。互联网收集各种各样的服务和资源。拉斯布鲁克，创新中心的主任兼顾问说互联网的主要组成是电子邮件和万维网。对于互联网来说还有更多的如。电子邮件，搜索引擎，快速网站，即时体育成绩，和充满淫秽讨论的聊天室。网络也被列为当今最好的商业工具——如果是熟练地运用”。几乎所有的家庭都拥有互联网；然而,在人们接触到互联网之前，他们需要知道它的缺点和优点。

Many fear the Internet because of its disadvantages. They claim to not use the Internet because they are afraid of the possible consequences or are simply not interested. People who have yet connected to the Internet claim they are not missing anything. Today’s technological society must realize, it is up to them to protect themselves on the Internet “Half of U.S. adults, or 94 million Americans, aren’t online”.

许多人都担心互联网的缺点。他们提出不使用互联网，因为他们害怕可能产生的后果或着是不感兴趣。那些还没有接触过互联网的人声称他们没有遗漏任何事情。如今的科技社会他们必须要意识到在互联网上保护自己“一半的美国成人，或着9400万美国人是不在线的”。

Children using the Internet has become a big concern. Most parents do not realize the dangers involved when their children log onto the Internet. When children are online, they can easily be lured into something dangerous. When children talk to others online, they do not realize they could actually be talking to a harmful person. As a result, there have been many cases where children have been convinced to meet people they have talked with online. In fact, “stories seem to come out every week: a child or teenager lured into something foolish, dangerous, or even deadly on line” . Cathy Cleaver of the Family Research Council claims that it is against the law for a molester to even attempt to find children online . In addition, children may also receive pornography online by mistake; therefore, causing concern among parents everywhere. Whether surfing the Web, reading newsgroups, or using email, children can be exposed to extremely inappropriate material.

Pornographic sites tend to make sure they are the first sites to be listed in any search area; thus, children come across such sites easily. A man from Pearl, Mississippi was arrested in 1996 for downloading pornographic images of children from the Internet. He was charged with 290 counts of child pornography . Some critics say that parents are responsible for their own children on the Internet because there are available services to protect children. To keep children safe, parents and teachers must be aware of the dangers. They must actively guide and guard their children online. Parents should talk to their children about what is online and what might happen online, claims Howard Rheingold, writer of The Virtual Community . There are a number of tools available today that may help keep the Internet environment safer for children. Some companies, such as America Online, try to monitor everything that is said and done on their online service; however, because thousands of chat rooms are available, it is simply impossible for everything to be monitored, claims Tricia Primrose, worker for America Online . In other words, children want to explore things; however, there are people on the Internet that are just too persuasive.

孩子们使用互联网已经成为一个大问题。大部分的父母都没意识到让他们的孩子接触互联网的危险。当孩子在网上时，他们会很容易地吸引到一些危险。当他们跟别人在网上聊天时，他们不知道他们可能正在跟一个有害的人聊天。因此，有很多情况是孩子被说服去见他们在网上聊过天的人。事实上，“这样的事情似乎每周都有：有孩子或少年在互联网上被一些愚蠢的，危险的,甚至是致命的东西诱惑”。凯西在家庭研究理事会上说性骚扰者甚至试图寻找在线的孩子是违反法律的。此外，孩子们也可能在网上无意的接触到色情信息；因此，导致世界各地的父母都担忧。不管是上网，阅读新闻组，或使用电子邮件，孩子们都可以接触到不合适的材料。色网站力倾保整他们是第一个网站列入任何搜索区域的网站；所以孩子们是很容易遇到这样的网站。一个来自密西西比州珍珠港的男人在1996年被逮捕，因为他从网上下载孩子的色图片。他被指控290项儿童色情。

一些批评家说，父母该对他们自己的孩子上网负责，因为有有效的服务来保护孩子。为了保护孩子们的安全，父母和教师必须知道其中的危险。他们必须积极引导和保护他们的孩子上网。“家长应该告诉他们的孩子网上有什么，网上可能发生什么事情，”《虚拟社区》的作家霍华德莱茵戈德说道。今天有很多可用的工具可能有助于为儿童保持安全的网络环境。有些公司，如美国在线，试图监控所有在他们网上服务器上的言语和行为，然而，由于有成千上万的聊天室，要监控所有的东西是根本不可能的，特瑞西亚·普林罗丝，美国在线的员工说道。换句话说，孩子们想要探索事情，但是，有些人在网上太有说服力了。

[网络危害英语作文

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.

这个冬天雾霾天气备受大家的关注,雾霾危害较大,有好几个城市已经中了它的招,所以我们应该增强环境管理的力度,不再让雾霾天气横行.

雾霾的成因想必有不少人知道,雾霾吗,当然是由雾和霾组成的,雾的主要成因是大量悬浮在地面空气中的微小水滴或冰晶组成的气溶胶系统,是近地面层空气中水凝结的产物.雾主要会使能见度降低,会造成交通隐患,但对人的危害不大.

霾是由空气中的灰尘、硫酸、硝酸等有害物质组成,它会使大气浑浊,视野模糊并导致能见度降低,并且会对人体造成较大的伤害.这样一来雾和霾两个本不相干的兄弟聚到了一起,对大气造成空前的破坏,有些城市的空气质量已经到了中度污染的地步,更有些城市已经达到了重度污染,非常可怕.

雾霾的危害相当大,它会对公路、铁路、航空、供电系统、农作物生长造成影响.还易导致传染病扩散和多种疾病发生.危害人的健康.并且会导致空气中污染物不易扩散,增强有害物质的毒性,严重的,还可能会导致毒雾发生.并且会对人造成巨大伤害,特别是对呼吸系统影响很大.有报道称,这个冬天呼吸系统发病的人比上个冬天增加了%30---%40.这是一个多么惊人的数字,值得我们深思.所以防治雾霾天气刻不容缓.

我们的防范措施应该到位,在雾霾天气时,我们应该停止晨练和户外运动.只是这样还不够,我认为造成这种恶劣天气的主要原因是汽车尾气的排放和工业生产废气的排放,所以国家应该尽快下达政策来管理和控制有害气体的排放,多植树种草,净化我们的环境.我想,如果大家都动员起来,雾霾天气就应该灰溜溜的逃跑了吧.

总之,我希望大家可以行动起来,多种草种花,多保护环境,为我们的子孙后代营造一个绿色,天然的环境.

Recent within a week, there is "anomalies" in our city haze. Peoples life has been affected by the smog. Around when I was a student, a grey, what also cant see. This Saturday, my father sent me to guzheng lessons, is coming, at that time, I didnt see the tall buildings around, thought dad lost!

General travelling is like pure milk, milk white, and gray haze is the, there are some bulbs. I am fog, haze do not understand, so today I have checked the online. Oh, it was so, fog is a large number of suspended in the air near the ground aerosol system composed of small water droplets or ice crystals, is the product of water vapor condensation in the air near the ground layer. The existence of the fog can reduce air transparency, make the deterioration of visibility, if the target level of visibility down to 1000 meters, will be suspended in water vapor condensation in the air near the ground like now known as the fog weather.

Haze also calls the ash haze, dust in the air, sulfuric acid, nitric acid, organic hydrocarbon particles such as atmospheric turbidity, blurry vision and led to the deterioration of visibility. With the deterioration of air quality, haze weather phenomenon appears, harm. Recently the haze weather phenomenon in many regions are merged into mist as a severe weather warning forecast together. Collectively referred to as "haze weather".

Fog can make the person "relapse", because of the fog haze contains bacteria, viruses and dust pollution, coupled with artificially industrial waste gas, automobile exhaust and so on, seriously affecting peoples health. Now, some of the students in our class has a bad cold, does everything listless, a sickly appearance. So you must protect have holes in the earth, protect the environment, starts from me, let the blue sky white clouds accompany us forever!

最近一星期内，我们城市里出现了“异常情况”——雾霾。雾霾严重影响了居民的生活。在我上学时，周围灰蒙蒙，什么也看不清。这个星期六，爸爸送我去上古筝课，快到了，当时我没有看到周围的高楼大厦，还以为爸爸开错路哩!

一般雾都是跟纯牛奶一样，是乳白色的，而霾是灰色的，还有点儿呛鼻。我对雾，霾并不了解，所以我今天特意上网查了一下。哦，原来是这样啊，雾是有大量悬浮在近地面空气中的微小水滴或冰晶组成的气溶胶系统，是近地面层空气中水汽凝结的产物。雾的存在会降低空气透明度，使能见度恶化，如果目标物的水平能见度降低到1000米以内，就将悬浮在近地面空气中水汽凝结物的天气现像称为雾。

霾也称灰霾，空气中的灰尘，硫酸，硝酸，有机碳氢化合物等粒子使大气混浊，视野模糊并导致能见度恶化。随着空气质量的恶化，阴霾天气现象出现增多，危害加重。近期我国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报。统称为“雾霾天气”。

雾霾能使人“旧病复发”，因为雾霾里包含细菌，灰尘和病毒等污染物，再加上人为地工业废气，汽车尾气等，严重影响人们的身体健康。现在，我们班里的一些同学得了重感冒，做什么事都无精打采，一副病怏怏的样子。所以大家一定要保护已经千疮百孔的地球啊，保护环境，从我做起，让蓝天白云永远陪伴着我们!

周六早上七点去检查眼睛，八点四十分就结束了。原以为会耽误上科技课，特意向科技老师请了假。我们一看时间还来得及，赶紧打车直奔科技馆。

因为前几天的雾霾严重，PM2.5频频爆表，科技老师想向学生们介绍形成雾霾的主要原因，大家一起探讨如何防治雾霾。课上，学生们列出了雾霾形成的部分原因：工业、农业、气候以及生活方面的因素造成了现如今的雾霾。

老师为了让学生们直观地了解气候对雾霾的影响，特意找出四个小瓶。先用冷水装入墨水代表受污染的环境，在冷水上面倒放一瓶热水，大家发现污染过的水并没有什么变化。而如果装入污染过的热水，在上面上倒放一瓶冷水，受污染的热水就会缓慢上升，染污物就会飘浮混入到上层。通过观察近期气温变化，我们可以发现雾霾的那几天气温普遍偏高，不利于污浊的空气流通。而在气温偏低有北风时，就没有了雾霾。因此，风力和气温对雾霾是有清除作用。

大家又选取了香、木炭、酒精灯燃烧，在同样的位置，用PM2.5测试仪。测试结果发现，香的燃烧产生大量的PM2.5，瞬间就爆表了。这一现象让大家以后要远离寺庙，减少烧香。在室内也不要燃香，容易造成空气中的PM2.5超标。而大家印象中的木炭在燃烧的过程中，并不会产生太多的PM2.5，但在食用烧烤食品时，烟物也会产生对人体有害的物质，平时生活中也不要多吃烧烤和油炸的食品。这些测试只是产生一些简单的一次颗粒。在实际生活中，还会有许多二次颗粒对大气造成污染。

老师又带领学生做了一个氨气加盐酸混合的实验。当氨气与盐酸接触后，产生的混合气体也使测试表瞬间超值。在日常生活中，许多混合的气体也会产生大量的PM2.5。现在，北京治理环境，把首钢迁走了，但在河北遍布着许多钢铁生产厂，这些高耗能的工业会产生许多废弃物，影响环境。中国经济高速发展的代价之一就是环境问题，希望在近二十年内，有人能想出一些缓解的办法，让我们能够自由、健康地生活在自己的家园。

A heavy fog in people unwittingly quietly. Just get up early in the morning, they saw a piece of white, outside ah, again under the fog.

In recent weeks that dont know why the air, almost every week to a heavy fog, a door, foggy, street as if into the opaque vertigo hole, the ivory like light smoke and fog in opaque gauze, around the side all the time.

Walk on the road, only to see his side of things, even the opposite of tall buildings have been fuzzy see not pure, turned suddenly see cant see the end of the car on the road, then take a look at the weather of hate, I seem to see the factory chimney emissions of black smoke, I seem to see the fireworks away after that all the smoke, I seem to see the burning smoke all over the sky...

Many people may not have thought that the fog is how come of, because there will be fruit, when the road traffic is more than a day, a day when the firecrackers "crackling", it is destined to we must eat the bitter fruit. See during the Spring Festival, alway the fireworks amount is less than normal, but the business openings put firecrackers is more than the Spring Festival and Lantern Festival, a good I port view, however, the port view change back is not only a visual feast, again and again is the haze weather, the elegant and fine particulate matter in the air, generally mask did not resist, will only bring hurt again and again.

Automobile exhaust, heavy metals, dangerous chemicals, electronic waste, and soil caused by environmental problems have threatened human health and public safety, let us act, starts from me, contribute to protect our home!

一场大雾在人们不知不觉中悄然而至。一大早刚起床，就看见外面白茫茫的一片，哎呀，又下雾了。

最近这几周这空气也不知道是怎么了，几乎每周都要来上一场浓雾，一出门，大街上浓雾弥漫，仿佛走进了伸手不见五指的迷魂洞，那乳白色的雾像轻盈的烟尘又似穿不透的薄纱，时时刻刻围绕在身边。

走在路上，只能看清楚自己身旁的东西，连对面高大的楼房都已经模糊看不清了，转头却突然看到了马路上看不到尽头的汽车，再看看这讨厌的鬼天气，我仿佛看到了工厂烟囱排放的滚滚黑烟，我仿佛看到了烟花散去后那满天的烟尘，我仿佛看到了焚烧秸秆的漫天浓烟……

很多人可能没有想过，这雾霾是怎么来的，有因必有果，当马路上的车流量一日比一日多的时候，当鞭炮“噼噼啪啪”响起的时候，就注定了我们一定要吃这样的苦果。看看春节期间，好容易这烟花量比往年少了一些，谁知这商家开业及元宵节放的鞭炮比春节都多，好一个火树银花不夜天，可是，这不夜天换回来的不仅是一次盛大的视觉宴会，更多的是一次又一次的雾霾天气，这飘逸在空气中的细小颗粒物，一般的口罩根本抵挡不住，只会给人们带来一次又一次的伤害。

汽车尾气、重金属、危险化学品、电子废物、土壤等引发的环境问题已经威胁人体健康和公共安全，让我们行动起来，从我做起，为保护我们的家园做出贡献!

Another haze weather, the visibility to hundreds of meters. Both vehicles and pedestrians in feeling, without laughing, also do not have the bird, in such an environment, there are only pungent odor, and dark.

Fog, originally like smoke, such as gauze, like a gauze over the earth. How many men of letters through the ages, it has to, to dump. Now with this beautiful fog fog seems to have a relationship, and made what mistake?

Fog haze, seemingly "blood relationship" with the fog, but it is very different and fog. The mist, is floating in the air water vapor condensation of water droplets or ice crystals. Sometimes fog forecast sunny, sometimes the forecast of rain, fog appears to be chaotic, but as long as to master the characteristics of radiation fog, advection fog, observation, careful analysis, can accurately grasp the fog and sunny, rainy, in order to predict the weather. For the agriculture, transportation, aerospace, navigation is useful. And haze is different, it is made of the dust in the air, sulfuric acid, nitric acid, and organic hydrocarbon particles composed of gray.

又是一个雾霾天气，能见度不足以百米。无论是车辆还是行人都在摸索前行，没有了嬉笑，也无了鸟鸣，在这样的环境里，有的只是刺鼻的气味和满目的昏暗。

雾，原本似轻烟，如薄纱，似纱巾笼罩着大地。古往今来，它曾让多少文人墨客为之陶醉，为之倾倒。而今与这美丽的雾貌似有着一丝关系的雾霾，又犯下了什么滔天大罪?

雾霾，看似与雾有“血缘关系”，但它却和雾截然不同。雾，是由浮游在空中的小水滴或冰晶组成的水汽凝结物。有时雾出预报晴，有时雾出预报雨，似乎混乱不堪，但是只要掌握了辐射雾、平流雾的特征，多方观察，仔细分析，就能准确地抓住雾与天晴、落雨的规律，以便预测天气。这对于农业、交通、航天、航海都有用处。 而雾霾就不一样了，它是由空气中的灰尘、硫酸、硝酸、有机碳氢化合物等粒子所组成的小灰粒。

I saw you through it, faint, so distorted; Through it, I see the dark gray day, dangerous; I saw this busy city, through it, but are confused MuYun. I through it, as though covered with a layer of yarn, but not white, does not light. You am in the shadow of the people, the fog haze! When you can recede.

I have a small masks, masks, haze body around completely, I feel lost and sad, why should meet haze? Why cant isolated from it? My mask, contains not only the haze, and sad. The rapidly changing, clear of renewal, which fills the world how can become cant see? The gorgeous neon lights, under the haze, but also a group of colored clouds. Under the fog haze, everything is so bad, though is hazy, but without any artistic conception, just hate and sadness.

We will meet and fog haze "prompt", why do I not happy? I was so wanton destruction of the environment, is not waiting for the arrival of the fog? Why is that?

Verbal complain, people are floating clouds, there is no use. The work is to protect the fragile nature and irascible "Sir"!

Said ok, dont gossip, I take for the subject "meet with fog", although this is you dont want to, because I want you to understand that the consequences of doing so, will be unimaginable!

我透过它，看见了你隐约的身影，多么扭曲;我透过它，看见了黯淡的灰天，多么扑朔迷离;我透过它，看见了这个繁华都市，只不过都是迷茫暮云。我透过它，仿佛蒙上了一层纱，但并不洁白，并不轻盈。你是万千人民的阴影，雾霾啊!你何时才能退去。

我有着一个小小的口罩，口罩外，围绕着团团霾体，我感到失落、伤心，为何要与雾霾相约?为何不能与它隔离?我的口罩，包含的不只是这霾体，还有伤心。这个瞬息万变、万象更新的清晰大千世界，怎么会变得看不清?那华丽绚烂的霓虹灯，在雾霾下，也不过一团彩色乌云。在雾霾下，一切都是那么不如意，虽说是朦胧的，但却没有任何意境，只是憎恨和忧伤。

我们都会与雾霾相约“九八”，我为何高兴不起来?我那么肆意的破坏环境，不就是等着雾霾的到来吗?为什么?

人们口头上的抱怨，都是浮云，没有任何用处。最管用的是好好保护大自然这位脆弱而又暴躁的“先生”吧!

好了，闲话不多说，我之所以题目取为“与雾霾相遇”，尽管这是大家不想要的，是因为我想让大家明白，这样做的后果，将不堪设想啊!

雾霾天气的危害

最近这段时间经常听说雾霾，本来以为这是其他地方受苦了，没想到早上一起床，发现周围已经是雾茫茫一片了。雾霾天气来袭，不知道会给人们带来多少不便!

最近这几周这空气也不知道是怎么了，几乎每周都要来上一场浓雾，一出门，大街上浓雾弥漫，仿佛走进了伸手不见五指的迷魂洞，那乳白色的雾像轻盈的烟尘又似穿不透的薄纱，时时刻刻围绕在身边。

走在路上，只能看清楚自己身旁的东西，连对面高大的楼房都已经模糊看不清了，转头却突然看到了马路上看不到尽头的汽车，再看看这讨厌的鬼天气，我仿佛看到了工厂烟囱排放的滚滚黑烟，我仿佛看到了烟花散去后那满天的烟尘，我仿佛看到了焚烧秸秆的漫天浓烟……

很多人可能没有想过，这雾霾是怎么来的，有因必有果，当马路上的车流量一日比一日多的时候，当鞭炮“噼噼啪啪”响起的时候，就注定了我们一定要吃这样的苦果。看看春节期间，好容易这烟花量比往年少了一些，谁知这商家开业及元宵节放的鞭炮比春节都多，好一个火树银花不夜天，可是，这不夜天换回来的不仅是一次盛大的视觉宴会，更多的是一次又一次的雾霾天气，这飘逸在空气中的细小颗粒物，一般的口罩根本抵挡不住，只会给人们带来一次又一次的伤害。

雾霾的危害相当大,它会对公路、铁路、航空、供电系统、农作物生长造成影响.还易导致传染病扩散和多种疾病发生.危害人的健康.并且会导致空气中污染物不易扩散,增强有害物质的毒性,严重的,还可能会导致毒雾发生.并且会对人造成巨大伤害,特别是对呼吸系统影响很大.有报道称,这个冬天呼吸系统发病的人比上个冬天增加了%30---%40.这是一个多么惊人的数字,值得我们深思.所以防治雾霾天气刻不容缓.

我们的防范措施应该到位,在雾霾天气时,我们应该停止晨练和户外运动.只是这样还不够,我认为造成这种恶劣天气的主要原因是汽车尾气的排放和工业生产废气的排放,所以国家应该尽快下达政策来管理和控制有害气体的排放,多植树种草,净化我们的环境.我想,如果大家都动员起来,雾霾天气就应该灰溜溜的逃跑了吧.

雾霾天气和我们的环境受到污染有很大的关系，只有当我们行动起来，保护环境，保护我们的家园，才能远离雾霾，让我们的家园恢复它原本的美好，才能让我们的生活越来越舒适!

今天的天气真奇怪,早晨还是多云的天.到了下午6点钟左右,天边渐渐泛起一层薄薄的雾气,笼罩着远处的山头.

我还以为是夜色朦胧了天边.隔了五分钟,当我再次伏在窗边眺望远方时,意外地发现窗玻璃上多了一些颗粒状的小水珠,细细端详,每一颗小水珠里都包含着一团小小的黑色灰尘微粒,我好生奇怪.再放眼往远处看,高大的楼房仿佛系上了一条条轻柔的白纱,霓虹灯点缀的彩带也越发缥缈起来;停车场上过往的车子也开启了雾灯,射出的灯光如同一根根光柱,很耐看.天渐渐暗了下来,窗上的水珠越集越多,慢慢地,小水珠吮吸得越来越大.窗外的一切是那么的静谧美好,我不禁也被深深吸引了……正当我陶醉之时,一道闪电划过天空,伴随着雷电,大雨倾盆而下.雨水拍打着玻璃,尘土也被冲刷得干干净净.刚刚的雾蔼,也被吹得没有了影子.

咦,这不就是自然书上所说的雾霾现象吗?

我翻出家里一本厚厚的《十万个为什么》,哈,终于找到了——对,这就是雾霾!它是因为空气中悬浮着大量的烟、尘等微粒遇到水气而形成的混浊现象,使视线模糊并导致能见度下降.怪不得窗玻璃上有星星点点的微粒,原来是空气中的灰尘在作怪啊!

因为现在空气污染越严重,所以雾霾天气就越多,危害也就越大.有时会使汽车不能开,飞机不能降落.

要减少雾霾天气,我们必须要保护环境,多植树多种草,提高空气质量,为人类造福.

希望同学们能够通过这篇关于雾霾的作文,深刻的认识到我们所处的环境是多么的恶劣,希望同学们能够保护环境.

In recent days, the sky is very gray, can not see the sun, give a person a kind of chilly. You see: close, plant area of two cooling towers, looming; In the distance the mid-levels, gone. Also let a person mental laziness, depressed all day. Newspapers, television publicity: recent haze, out less and less as far as possible to open a window. Visible haze serious air pollution, the air quality to drop, affect human body health. I would like to know the fog haze and its harm to people, then go online to check, it was "dont know, a look startled!"

There are hundreds of different fog atmospheric chemical composition of particulate matter. Among them include: organic aerosol particles, fuel, and automobile exhaust. It can directly enter and adhesion in the human respiratory tract and alveolar, cause acute rhinitis and acute bronchitis. For obstructive emphysema, bronchial asthma patients, such as fog weather condition of acute attacks. If this kind of environment for a long time, will also cause cancer.

It have an impact on the cardiovascular system. Pollutants in haze weather, low air pressure, easy to cause acute episodes of cardiovascular system. Such as heavy fog, the water vapor content is high, if people in the outdoor sports, can cause chest tightness, high blood pressure and other symptoms.

Haze weather can also lead to nearly formation ultraviolet ray is abate, infectious germs. Due to the lack, children lack of ultraviolet irradiation, vitamin D production, for the absorption of calcium, cause rickets in infants, growth slows down. Will directly affect peoples mental health, mental laziness, depressed, etc. No wonder these days the mood will be so happy.

Point of view, to eliminate the fog, we should reduce waste emissions; Reduce the dust; Especially to do less drive a car, use public transit. In order to better tomorrow, lets start environmental action today, the blue sky, green water, green and quiet we need to create your own!

最近几天，天空都是阴沉沉地，看不到太阳，给人一种冷飕飕的感觉。你看：近处，半山电厂的两个冷却塔，若隐若现;远处的半山，没了踪影。还整天让人精神懒散、心情低落。报纸、电视都在宣传：近期雾霾严重，要尽量减少外出、少开窗户。可见雾霾严重污染空气，使空气质量下降，影响人体健康。我很想了解雾霾对人的危害，于是上网去查了一下，真是“不看不知道，一看吓一跳啊!”

雾霾有数百种大气化学颗粒物质组成。其中就包含：有机溶胶粒子、燃料和汽车废气等。它可以直接进入并粘附在人体呼吸道和肺泡中，引起急性鼻炎和急性支气管炎。对于阻塞性肺气肿、支气管哮喘等患者，雾霾天气会使病情急性发作。如果长期处于这种环境，还会诱发癌。

它对心血管系统有影响。雾霾天气中污染物多，气压低，容易引起心血管系统的急性发作。比如雾大的时候，水汽含量高，如果人们在户外运动的话，会造成胸闷，血压升高等症状。

雾霾天气还会导致近地层紫外线减弱，传染性病菌滋生。由于日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收减少，引起婴儿佝偻病，生长减慢。还会直接影响到人们的心理健康，让人精神懒散、情绪低落等。难怪这几天心情会这么不舒畅。

看来，要消除雾霾，我们要减少废弃物的排放;减少扬尘的行动;尤其要做到少开汽车，多用公交出行的方式。为了更好的明天，让我们今天就开始环保行动吧，蓝天、碧水、绿色、清静需要我们自己创造的!

In recent weeks that dont know why the air, almost every week to a heavy fog, a door, foggy, street as if into the opaque vertigo hole, the ivory like light smoke and fog in opaque gauze, around the side all the time.

Walk on the road, only to see his side of things, even the opposite of tall buildings have been fuzzy see not pure, turned suddenly see cant see the end of the car on the road, then take a look at the weather of hate, I seem to see the factory chimney emissions of black smoke, I seem to see the fireworks away after that all the smoke, I seem to see the burning smoke all over the sky...

Many people may not have thought that the fog is how come of, because there will be fruit, when the road traffic is more than a day, a day when the firecrackers "crackling", it is destined to we must eat the bitter fruit. See during the Spring Festival, alway the fireworks amount is less than normal, but the business openings put firecrackers is more than the Spring Festival and Lantern Festival, a good I port view, however, the port view change back is not only a visual feast, again and again is the haze weather, the elegant and fine particulate matter in the air, generally mask did not resist, will only bring hurt again and again.

Haze weather and the pollution of our environment has a lot to do, only when we act to protect the environment, protect our homes, to stay away from the fog haze, to let the goodness of our home had to restore it, to make our life more comfortable!
