Pollution Haze

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.

亲爱的比尔,

我很高兴收到你的来信，谢谢你关心我的天气和我的健康。现在我想告诉你们一些关于雾霾的事情。

自去年冬天以来，雾霾已经发生了很多次。这对我们的日常生活造成了很大的伤害。只是因为发生了许多交通事故的烟雾天气,越来越多的人去看医生因为烟雾造成的严重的疾病,很多的航班不得不推迟,许多人不得不留在家里,以免造成的空气有毒烟雾。

人们已经意识到雾霾带来的巨大危害以及保护环境的重要性。全国各地的人们都在采取措施减少雾霾天气。政府建议人们去上班或上学，比如公共交通，比如公交车和地铁。我们也应该种更多的树。

根据我的说法，我将骑自行车或步行去上学，我不会把垃圾扔到任何地方。此外，我会告诉我所遇到的人尽可能地保护环境。你能告诉我一些好主意吗?我期待着你的答复。

雾霾来了，早晨，我从暖暖的被子里爬起来，一副没睡醒的样子，迅速穿好衣服，准备去外面做晨练。刚从房间走出来，透过窗子。看见外面那么大的雾霾，顿时连做晨练的心情就没有了。

雾霾太大了，整个一白茫茫的世界。一想到妈妈说，吸多了雾霾，对身体有伤害。就赶忙朝着屋子走进去，一片白茫茫的世界，完全看不见东西，我只能摸着，慢慢的一步一步向前挪。好不容易靠感觉走到了屋子，在窗户外面看看雾霾是什么样子的吧，哇!外面一片白色呀！什么也看不见，整个一白色的天堂。因为雾霾太大，爸爸妈妈就没去上班，因为雾霾天气，我们大家要时刻记住保暖哦!大家也要记住，雾霾天去尽量不要出门。                                                   我眼中的雾霾是有害的，不知，你们眼中的雾霾是什么样的呢？

Today s Sunday, stadyed up late yesterday, got up at : th s morn ng. fter breakfast. y mother and me take a truck to the farm.Because e must helped my uncle to p ck the apples.The apple trees are too tall, helped them to crry the apples to the truck.Somet me had an apple, t as very.The ather people talked about the apples happ ly,somet mes they laughed loudly. e enthome at f ve n the aftermoon. asvery t red,but as very happy. 快来看咯！

今天，学校里起了雾，不，是起霾了。老师给我们布置了一篇关于霾的作文。

听一个同学说，雾和雾霾是有区别的：雾是浓浓的白色的;而霾是有着昏黄色的化学物质的有害气体组成的，含有程度很高的Pm2.5，有毒，所以出门要带“防霾口罩”。而且雾有一定的范围，霾没有。

那霾又是由什么而来呢?原来，许多化工厂排出的废气和废水中含有大量有毒物质，它们被从废水中飞起中随水蒸发掉混进空气中导致雾霾形成的。

所以，我建议国家停下一些工厂。可为什么那些老板为什么要开工厂呢?还不是他们为了利益不惜一切代价。那些老板为了金钱不懂得爱护地球。

除了工厂，还有伐木场把很多树木砍掉去买，还说是造家，可他们哪里知道我们的家早已经建好了，但动物的家就毁了，我们为什么就谁都做不到“将加人，先问己”的这个道理呢?

如果可以，我愿不惜一切代价将地球的环境变得美好。让雾霾，沙漠化，酸雨这些东西离开我们宝贵的地球!

我在学校5年多了，从未想过我会走出这个校园。可是，事实是不能改变的。

母校给了我们温暖，我们每一个同学都不想离开我们的母校。老师就像辛勤的园丁，在我们渴了的时候，把知识的甘霖给予我们；在我们烦恼的时候，她总会用滑稽的言语逗我们开心。我还要感谢每一个教我们的老师让我们都学到了知识尤其是刘老师就是我们的英语老师他长着浓浓的眉毛一双眼镜挂在鼻梁上看起来很有学问。

每一次在我们上英语课的时候刚上课便说“上课了同学们快背学了都是自己的啊。“我们都很烦躁在我们心情不好的时候他会讲一个笑话有一次我记得这样一个故事：有一个人啊造假钱希望买价钱少的物品让人家给他更多的真钱有一次他来到一个农村为什么呢因为农村人不懂骗人的诈术便来到一个小卖店来到卖店门口说：“老板来一根棒棒糖说完给老板一张15元的钞票老板是城市里来的便给他一支棒棒糖又给骗子一张14元的钞票”。骗子蒙圈了心想：他怎么也有啊。又和老板说：“你哪来的钱啊我都没见过啊”。老板笑着说：“小伙子别以为农村人就没见过世面对付你这种小骗子我在城市见多了自然也就习惯了这棒棒糖你就拿去吃吧以后别骗人了。”小偷恍然大悟：“哦原来我来晚了。”我们同学听后都笑了，都说老师很幽默。这就是我的英语老师，这样一个有知识而且又幽默的老师。

可是，我们快要毕业了。不想离开母校也不知道毕业后什么时候会再见到英语老师。时间啊，你慢慢走，让我们多陪陪我的老师们吧。

近几天雾霾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。

大清早，刚睁开眼，看到外面灰蒙蒙的，还以为今天是阴天，而天气预报却说是晴天，原来这一切都是雾霾惹的祸！

想起这几天老是无缘无故的咳嗽，我才知道，这都是雾霾惹的祸。这几天，都有严重的雾霾，而我每天都会大口大口的呼吸，使雾霾中的灰尘都统统跑进了我的嘴里，我不管什么时候都咳嗽了起来，咳出来的痰都是黑黑的。妈妈跟我说，今天不能多出去运动。走在上学的路上，大家都带着口罩、围巾，把自己裹得严严实实的，只留下两只眼睛可以看得见。终于到了我们最喜欢的“大课间”时间了，学校却通知，因为雾霾，取消一切的户外活动，我们又少了锻炼身体，尽情奔跑的机会了！

哎，看把大家给折腾的，希望这些口罩真的能有用。

关于雾霾

Since the winter last year，the haze has occurred a lot of times.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.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.

it has done great harm to our daily life.many traffic accidents happened just because of the heavy haze weather，more and more people have to go to see the doctor because the serious disease caused by the haze，quite a lot of flights have to be put off，a great number of people have to stay at home for fear of the poisonous air caused by the haze.

People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic， such as the bus and the underground.Also we should plant more trees.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 operationsAccording to me， I will go to school by bike or on foot， and I won’t throw the waste anywhere.in addition， I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas？i’m looking forward to your reply. We are all in this together！ We shall survive and thrive together！

关于雾霾的解决方法

Dear David,

I’m glad to receive your letter. I have learned from your letter that you are concerned about the smog which frequently appears in some areas of China. Thank you for your concern. I’m also very worried about such terrible weather because it has brought much inconvenience or rather harm to people’s health such as traffic jam, road accidents, bad coughs, throat hurts and ever lung cancers and so on.

As everybody knows, a good environment comes from good protection. So we should do what we can to make a difference. Try to drive less and choose air-friendly products. Only when everyone has the environmental awareness can we have cleaner air.

Hoping to hear from you soon and share your good ideas.

雾霾问题深深影响我们的生活?

看着窗外灰蒙蒙的天气，我问爸爸：“这是什么自然现象?”他回答道：“这是雾霾，一种有害物质。出门要戴口罩的，不然会吸入有毒气体，得肺癌，和吸烟差不多。”原来这是有害气体啊。我吃完早饭，准备去上学。在路上，三米内，几乎看不见一个人。雾越来越大，我从没见过这么大的雾。我走之前，顺便在手机上看了一下“天气预报”，今天是“重度污染”，穿衣小助手还提示：出门要带口罩。雾霾里面有一种毒叫做“PM2。5”，对人体有极大的危害。如果把口罩拿下来，就会吸入有毒气体，若不拿，就觉得憋着难受，真是两难呀!

到了学校，上完了第一节课，本以为会想以前一样出去做早操、跑步，但广播播道：“请各位同学在教室里活动，因雾霾天气影响，暂停跑操、早操等活动。”教室里面引起了一阵骚动，大家叽叽呱呱地谈论着雾霾，我认为，雾霾太大了，竟然导致一系列的活动不能举行!我们在谈论中度过了大课间。第二课上完后，迎来了我们最爱的微机课。微机课是要到微机室上的，但是我们要经过有雾地区，又引起了一阵阵纠结。没办法，硬拼吧!我在教室里做了深呼吸，准备途中不呼吸一口气，直接冲过去。我把我这个想法告诉了我的好朋友，她笑道：“你可真行，要跑过两个操场呢!你能憋得了吗?”我无奈地说：“那能怎么办?口罩也不想带，到微机室再装给口袋里，岂不会弄脏了吗?总不能，途中再呼吸几口吧?”“为何不行?只是吸几口，不碍事的。”我还是有所担心：“这空气要是像吸烟一样吸上瘾呢?算了吧，我还是最好戴口罩!”她看了看我，哭笑不得。

微机课前大灾难度过了，我们上完了愉快的微机课。准备去站放学路队。突然，一声惨叫：“呀!你踩着我了!”我只好抱歉地说：“雾太大了，不好意思啊。”直到中午，雾霾还未散去，它就像一个顽皮的小孩，不愿离开他心爱的玩具，依然逗留在这里。

雾霾，真大!人们在埋怨这霾大得过分，可这会不会是自己未爱护环境而造成的呢?我们是否也该自己反思一下?

I am a girl of ten, and I live in a small mountain village far from Taiyuan. The only person that lives with me is my mother, because my father is away for eight years, working in a city.

我是一个十岁的女孩，我住在离太原很远的一个小山村。这与我的生活的唯一的人是我的妈妈，因为我父亲离家已经八年了，在一个城市工作。

During the Spring Festival, my father came back home. He looked thin and tired. He gave my mother two thousand yuan, and told her that he would work even harder, earn more money, and then he could take us to the city He stayed at home for only ten days.We are living a poor life now. But what I want most is not money, but my father. I miss him very much!

春节期间，我的父亲回到家里。他看起来瘦瘦的，很累。他给了我母亲二千元，并告诉她，他会更加努力工作，赚更多的钱，然后他可以带我们到他呆在家里，只有十天的城市。我们生活在一个贫穷的生活。但我最需要的不是钱，而是我的父亲。我很想念他!

I will have a seven-day holiday next week. In these days, I have many things to do. First, I must finish the exercises left by teachers, Chinese, math and English. It may take me two days to finish. I plan finish them in the first and second day. And then, I will go to see my grandparents with mom and dad. I miss them very much. So do they. I will stay there for three days. The last two days, I want to have a good rest or play with my friends. It’s my own time, so that I want to spend it with my friends. This is my plan for the holiday. What about yours?

下周我将有七天的假期。在这几天我有很多事情要做。首先，我必须完成老师布置的作业，有语文，数学和英语。完成这些作业要花我两天的时间。我打算在第一天和第二天完成，接着我会和爸爸妈妈去看望爷爷奶奶。我很想念他们，他们也很想念我们。我会在那里待上三天。最后两天，我想好好休息或者和我朋友一起玩。这是我自己的时间，所以我想和朋友一起度过。这就是我的假期计划。你的计划是怎么样的呢?

暑假一转眼就过了一半了，而在我前一半的生活可以说是比较充实，下面就让我说一说我暑假的生活吧。

暑假作业不可以少，这个暑假的作业量不算多，所以我每天三张钢笔字，五页愉快暑假的速度来完成的，在写完了作业之后我都会看看书，每天看个半小时，不但不会让让我的阅读水平不会掉下来。还可以让我明白很多的道理。

在这个暑假里，不只有写作业，旅游也是暑假里不会少的一件事，我在这个暑假去了有名的武夷山游玩，在武夷山我游玩了雄伟的大王峰，十分窄小的一线天等一些美丽的地方。我认为我这个暑假可以算得上是游山玩水了。

暑假里，我和我的朋友还去玩了几次密室逃脱，让我收获很多。也让我明白了团队合作十分重要。暑假中运动也十分的重要。我每天都会去和朋友一起去打篮球让当天的烦恼随着汗水流泄出来。

时光总是那么的短暂，但在短暂的时光时我们不是都在学到十分多的道理，希望时间能过得慢一点，这样我们就能学到更多的道理。

以前“雾”总是一个人孤零零来到我们的身边，现在“雾”带着它的好兄弟——“霾”一起来到我们的身边，雾霾也叫PM2·5。

PM2·5可是有毒的哦。它能较长时间悬浮于空气中，在其空气中浓度越高，就代表空气污染越严重。与较粗的大气颗粒物相比，它粒径小，面积大，活性强，易附带有毒、有害物质，且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响更大。可是这么恶劣的天气是谁造成的?是我们人类乱砍滥伐，乱丢垃圾，随地吐痰，排放废气、废水等一些不文明的行为造成的。

当雾霾来临时，从家里的窗户向外望去，白茫茫的一片像一层层薄纱似的笼罩着大地。从车里向外望，车子被雾霾紧紧的包围着。这样的天气让人们不由得带上了口罩，加快了脚步。路边的花花草草都垂下了头。学校的大课间和早锻炼都被迫取消了，现在的操场上，没有了往日的吵闹声、嬉戏声。每一个在户外的同学都快速地冲向自己的教室，生怕雾霾带来的影响。同学们只能呆在教室里。校园里一片寂静，再也没有了往日的生机。

“雾”啊“雾”，请你把你的坏兄弟赶走吧，我们人类不欢迎他。

放学回家，我看到奶奶戴着一幅厚厚的老花镜，戴着一对耳机，嘴里念念有词：“A，B，C，D……。”

我放下书包，悄悄地走过去，看见录音机在播放着呢！天哪，奶奶怎么学起英语来了，前两天她还说我在学“鸟语”，怎么现在奶奶学起“鸟语”来了。

我做完作业，要听录音了，我走过去对奶奶说：“奶奶，我要听录音了！”奶奶也许听得太认真了，并没有察觉我在她身边。我大声喊：“奶奶”。这才回过头来，说：“这玩意挺好玩的，你给我买一个吧。”我听了，差点晕过去。奶奶又发话了：“孙女，banana是香蕉的英文，是吗？再借我听听呗。”我唉声叹气，真是哑巴吃黄莲——有苦说不出，只好耐心等待。

吃晚饭了，奶奶还在听录音，听出味道来了，“孙女，苹果是‘啊砰！A，P，P，啊哦，E，啊砰’！”我听了，立刻捧着肚子大笑起来，可奶奶完全不知道是怎么一回事，以为自己读得不错，还高兴地笑哩！

晚饭过后，奶奶以火箭般地速度冲向录音机旁，嘴里冒着一长串的“泡泡。”我尴尬死了，录音机被霸占了。现在又不能听了，只好等到奶奶走了后再听。

我等啊等，奶奶走的时刻终于等到了，“临走”前还对我说：“哎，人老了学什么都难。你可得好好抓紧时间，多学些知识和本领，不要像我这样，等头发白了才后悔莫及！”

她成了我学习的榜样，我也要对自己有信心。敢于设计自己的目标，朝着这个目标奋力前进，加油吧！

今天早晨，大雾弥漫，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。

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！
