六年级关于雾霾的英语作文实用2篇 作文怎么写（汇集20篇）

近期，雾霾天气频频发生，越来越严重，也引起了全国人民的注意和关照。中国不少地方把雾霾作为灾害性天气预报。

雾霾是怎样形成的呢?请听我慢慢道来。它是由PM2。5尘粒、烟粒、盐粒等均匀地浮在空中从而形成霾。不过，雾和霾还有本质上的区别。起雾时空气潮湿，出现霾时空气干燥，并且对人体有害无益，长期吸入会导致死亡。

雾霾又是怎样产生的呢?汽车尾气，工业生产排放废气，和鞭炮等都是雾霾的主要来由。少开一次车，少放一次鞭炮。让我们中国人不要再忽视环保。

不过，相对的自我保护也是要有的。为了避免吸入雾霾，雾霾天气切勿开窗。出去旅游，或者游玩时，请戴上口罩。多喝桐橘梗茶，并且适量补充维生素D。还要多喝水，饮食要清淡。

雾霾还会引发许多疾病，如呼吸道疾病、心血管疾病等，各种危害人体健康的大病。

保护自己，与雾霾做斗争是最重要的，雾霾虽然恐怖，但是人们还是想出许多办法与雾霾决战，如：人工降雨等。但是，这毕竟只能小范围短时间地控制雾霾，不是长久之计。所以，大家应该保护环境。

保护环境吧!让这几年的雾霾天气逐渐减少吧!让人们不用因此而死亡!

我眼中的雾霾是像空气中的魔鬼;我眼中的雾霾是时好时坏的;我眼中的雾霾是玩抓迷藏的好工具。

我在早上从宿舍出来时，我只能隐隐约约的看见大家的影子。我突然想起了在网上看到的话，我就按照上面的做了。到我们去吃饭时，从教室出来时，我发现现在看到的雾霾比早上时的更大，快到伸手不见五指的地步了。在今天有的同学生病了，我想应该是有雾霾的原因吧!这时，我感觉雾霾好像是空气中的魔鬼，不知不觉的就让同学生病的。

在课间时，有的同学在玩抓迷藏。等他们玩完时，我问了其中的一位同学说："你觉得好玩吗?为什么好玩呢?”他答道：“很好玩啊!因为今天有雾霾，有了雾霾的话我们随便的躲在一个地方找我们的人就找不到我们了。”听他回答完我的问题，我有感觉雾霾好像玩抓迷藏的好工具啊!

我眼中的雾霾既有好处又有坏处!

Dear Sir or Madam,

I’m Li Hua from Class One, Senior Two. As far as I am concerned, I believe to teach English for pupils from Chen Xi Hope School will be good for both the primary-school students and high-school student tutor, which thus will result in substantial social benefits.

I think I am qualified for being the pupils’ English coach, because I have good character, being independent in life and proficient in English. That’s why I apply for the position; I hope I can join the instructive activity.

My plan for coaching the pupils is to teach them by listening, speaking, reading and writing. What’s more important is to stimulate their interests in learning English as a foreign language, creating a good learning environment. I hope you can offer the opportunity.

Yours sincerely,

Li Hua

我们的身边有一位工作认真，对待学生细心、负责的好老师，她就是教我们英语的赵老师。

赵老师个子不高，讲起课来语速很快，不过我们也都适应了。她的课也许讲的不是最出色的，但她对我们无微不至的关心才是我喜欢她的原因。她说的每一句话都是有道理的，可能她说的时候你感觉不到，但事后你细细一想，也都不无道理。

她对学生日常生活也很关注。那是一年初夏，我和缪严寒、陈思豪都穿了长袖衣服到学校，在她的英语课上，讲课之余，她说到：“最近气温都升到了35度以上，可我们班有些同学还穿着长袖衣服，我希望你们明天把衣服换成短袖的。”

在我的印象中好像没有哪个老师会像赵老师那样关注我们，都做些什么，说些什么。在课堂上，她时时刻刻抓住我们的注意力，任何一个小动作，都逃不过她的眼睛。

这就是我的英语老师——赵老师。

Pollution haze

Recently, there arises a pressing problem confronting the protection of the environment. It is the haze weather, an air pollution in which is mixed up with dust, smoke and other dry particles. This phenomenon has aroused wide concern towards air quality.

As to this problem, there are several reasons accounting for my viewpoint. The most important reason for this is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air quality. The second important reason for this is motor vehicles. There is no denying that gas emission of private car is a great evil of air pollution. The third important reason is industrial fuel burning, I think. Industrial fuel burning leads to a large number of dust and poisonous gas breathed by people, healthy or not. All of above are manmade sources. Natural sources can include windblown dust, and soot from wildfire.

It has done great harm to our daily life. For example, everything around disappears from our sights. Many people, especially children and seniors, even find it difficult to breathe. As a result, local hospitals are crowded with people who have problems with their noses and lungs. In addition, many traffic accidents happen just because of the heavy haze weather.

Effective measures should be taken as soon as quickly to reduce the smog weather. In people, for one thing, people should go to walk or school by the public traffic, such as the bus and the underground. For another, it is indispensable to plant more trees. In government, taxing the owner of private cars should be adopted properly. According to me, I won’t waste anywhere, and go to school on foot.

I firmly advocate that all of us should take pains to protect our environment. If we work together to be able to do such measures, our environment will getting better and better and haze weather will vanish completely.

今天的天空是那么的灰蒙蒙。瞧，那飘扬的马尾辫，通红的手掌，瑟瑟发抖的身躯，那个女孩就是我。我要顶着雾霾去上学。

一出门，被污染的空气就直钻我的鼻孔，使我不停地咳嗽。那时的我多么想放弃啊，可是为了学习，我还是顶着雾霾去上学了。我想：人们应该吸取教训，采取一些有用的方案。

经过一路的灰尘，我终于来到了学校。一进校门，只见灰尘覆盖，门边的柳树拿树叶当口罩，小鸟不停地流着鼻涕。

我不停地奔跑着，不知不觉便到了教室。一切都是那么熟悉：黑板，讲台，课桌，书本，这一切都使我感到温暖。

这一天，我顶着雾霾去上学。

天灰蒙蒙的，又是一个雾霾天气，路上的行人戴着口罩艰难的呼吸着，路上的车依旧那么多，可是乘坐在车里的人，他们应该没带口罩吧。

雾霾不知什么时候成为天气预报的常客了，晴朗的天气越来越少了，我们讨厌这种天气。整天呼吸这样的天气，严重影响我们的身体健康，更恶劣的是带来不少疾病，像呼吸系统疾病，心血管病，癌症等等。雾霾不仅影响着我们的健康，也模糊了我们的视线，甚至影响到我们的正常生活，在家里连窗户都不敢开了。我们的心理上更是蒙了一层厚厚的土。

造成雾霾的原因是人类对大气的污染，工厂排放废气，还有就是图中的汽车排放尾气，汽车一族的不断增加，所带来的不仅是交通问题，还有严重的污染问题。大自然的自我净化处理能力已经受不住我们如此的折腾。所以市民现在应该有这样的反省，不能只为了自己方便，就给环境施加压力，应提倡绿色出行，公共出行，为美好的蓝天做出自己的一点努力。

In the picture it is a grey day and hazy weather.The pedestrians on the road wear gauze masks and it’s hard for them to breath. But there are still so many personal cars on the road , people in cars may not wear gauze masks,I think .

Hazy weather has become a frequent visitor to the weather forecast, and sunny weather become less and less.So people hate this bad,annoying,dirty weather. If we often breath such bad air，it will threaten our health. Because the bad weather cause a lot of diseases, such as respiratory disease, cardiovascular disease, cancer and so on. Hazy weather not only do damage to our life, but also blurs the sight of our eyes, even has a bad effect on our daily life.And opening windows everyday become luxurious. It’s a shock.Our heart is also covered a thick layer of soil. Living here we feel depressed.

What lead to the bad weather is mostly human pollution, for example industrial exhaust gas, burning, as well as automobile exhaust in this picture.The holders of cars is surging, which bring about not only the traffic problems, but also serious pollution problems.Nature’s purifying ability is out of her range. So citizens should have such consciousness, not their own convenience, but they should advocate green travel and give preference to public transportation. Only by doing this,can they make their own efforts to build up the blue sky once more.

“宝贝，快来把口罩戴上”最近几天，从来都反对带口罩的妈妈总是让我带口罩。因为现在淮安的空气质量非常不好，大家总是骂雾霾，可是又有谁知道，这雾霾的背后是人们没有环保意识而造成的呢？

外面的天气是一片灰暗，我的心也跟着充满灰意。“唰”一辆大客车从我眼前划过，汽车尾部，有一股黑烟匆匆而上，让原本灰暗的淮安城又“绣”上了一层危害。我捂着鼻子跑走了，这样的环境还能让人生存吗！“咳咳”我随声望去，原来是几个没有带口罩的路人呀。看到他们紧皱着眉头，我忽然想起这样严重的空气污染给人体也带来了许多不必要的危害——

吸入了太多空气中的细菌，大家都会知道对人体的肺部很不好，并且还会缩短人的寿命，这空气的污染带给我们的危害真的太多了！写到这里，我不由的把笔放下了，望着窗外灰蒙蒙的天空，我的心中不禁多了一丝担心，担心这样的空气到底要延续多久？这雾霾还会带给我们带来哪些伤害？这些雾霾仿佛住进了我的心里，令我陷入沉思……

但世界总是充满希望，每当我走在回家的路上时，总会看见一些身穿有黄色背心的清洁工阿姨们，而只有她们这些普通的不能再普通的人，才能带给我，带给社会一丝温暖。她们不分白天黑夜都辛勤的劳动，为我们美好的生活做出一身的奉献。如果每一个人都能向阿姨们一样，那这个世界该多么美好啊！我心想这些清洁工阿姨们带给我们多大的帮助啊！

同学们，让我们放下手中和笔，抛下脑后的烦恼抄起“武器”一起保卫我们的环境，我们的地球妈妈吧！就从随手捡起一片纸屑，少开一次汽车，世界将变的如此美好。手拉手，心连心，环保就从我们脚下，起航吧！

雾

她，仿佛一位羞于展露容颜的仙女，她不可捉摸，她调皮迷离；她莲步轻盈，她若隐若现；当你走近她时，她却了无踪迹。她就是雾，她是往昔的雾，她是我童年时的雾！

忆当年，那雾真的是一道靓丽的风景。她是乳白色的，薄薄的，淡淡的，轻轻的，极像少女身上披着的透明的轻纱。她围绕在你的周围，时而浓，时而淡，时而有，时而无，凉丝丝的，水漉漉的，飘悠悠的，真的如在梦境中一般。

当年的雾，好让人神往啊！

雾霾

它，黑黑沉沉；它，混混沌沌；它让天地浑然一体；它让人眼前暗无天日。它就是如今的雾，它叫雾霾，它就是如今令人讨厌的雾霾！

行走在路上，你总想极力的瞪大眼睛，来辨别前方和周围的一切。浓浓的雾和霾不仅严重的挡住了人们的视线，也挡住了车辆的视线。雾霾出现时，尽管汽车的大灯极力放射它的光芒，最终还是不能穿透浓雾，只有等距离很近很近了，才能恍惚看到两个模糊的小亮点。此时，所有的人和物，全都处于几近令人窒息的黑暗中！

雾是由地面空气中的水汽凝结而成的；而霾则是空气中极细微的灰尘颗粒、细沙颗粒、病毒颗粒等形成，它们均匀的悬浮在空气中，交织在一起就是雾霾天气。

我怀念和向往当年如梦似幻、如烟似纱的雾！我讨厌和痛恨如今如魔似鬼、如墨似漆的霾！强烈呼吁全社会所有的人们，从现在做起，从我做起，齐心协力，竭尽全力，共同消灭那害人的雾霾！

[ 雾和雾霾作文

导语：随着秋冬季节来临,雾霾天气也越来越严重,尤其是华北黄淮地区。雾霾天气是一轮接着一轮,市民只能等风来,靠冷空气吹散雾霾。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!

When winter comes, the topic of haze will never be ignored. When it comes, many pictures will be showed. People make fun of these pictures and they actually laugh at themselves, living with these poison air. Even in the daytime, people can’t see their faces beyond 10 meters. Many schools choose to stop the class and let the students stay at home. It is obvious that haze is a great threat to people’s health. This new type of destruction is the result of polluted environment. Businessmen chase for the profit and take the cost of polluting the environment. Now their offspring have to suffer from it. It is never too late to do something to protect our earth.

【参考翻译】

当冬季来临的时候，阴霾的话题永远不会被忽略。当雾霾到来的时候，人们会为它拍摄很多图片，之后再取笑这些照片。但是他们实际上嘲笑的是他们自己，因为他们生活在这些有毒的空气里。即使在白天，如果超过10米的话，人们都会看不见他人的脸。许多学校选择停课，让学生呆在家里。很明显，雾霾严重威胁到人们的健康。这种新型的破坏是环境污染的后果。商人们追求以污染环境为代价的利润，现在他们的后代都得遭受到恶果。现在为保护我们的地球付出努力还为时不晚。

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。

Just go out, find day yellow, is wrong! Mother said; "It seems to be under the storm!"

Walk, feel the chest is very stuffy, look at things like float up, dizzy. The dirt and dust is in the sky, with a trace of fear. The sky is gray, the air is damp, give a person a kind of depressed feeling.

The next day on the language class, the teacher let us discuss the haze weather yesterday. Some students say its caused by some farmers burn weeds, some classmates say environmental contamination caused by... As for me, I think should also be caused by environmental pollution. In the end, or a teacher for us to solve the mystery. It turns out that this kind of weather because of environmental pollution and farmers burn formed by the union of weeds, but the teacher say again: "farmers burn weeds are merely a catalyst, the main or we cause environmental pollution." In addition, the teacher also adds some knowledge to us, let us say again that peace yesterday always have to differ? Just in the afternoon, I found some cars open headlight. XiaoYao found usually go to the bathroom in the morning you can see it dont need to turn on the light, and yesterday dont turn on the light does not see...

Fog haze let me know that this time must be to protect the environment!

刚出门，就发现天黄黄的，太不对劲了!妈妈说;“看来要下暴风雨喽!”

走着走着，就感觉胸口很闷，看东西就像飘起来似的，头晕晕的。天空中飘的不知是泥土还是灰尘，有一丝恐惧。天空灰暗，空气潮湿，给人一种很压抑的感觉。

第二天上语文课时，老师让我们讨论了一下昨天的雾霾天气。有的同学说是一些农民烧杂草所引起的，有的同学说是环境被污染所造成的……我呢，觉得也应该是污染环境所造成的。最后，还是老师为我们解开了谜团。原来，这种天气是因为污染环境和农民烧杂草结合形成的，但老师又说：“农民烧杂草只是一个催化剂而已，最主要的还是我们污染环境造成的。”另外，老师还向我们补充了一些知识，又让我们说了说昨天和平常有什么不同?我发现刚到下午，有些汽车就开大灯了。肖瑶发现平常早上上厕所不用开灯就能看见，而昨天不开灯就根本看不见……

这次雾霾让我知道了一定要保护环境才行!

This is my study habits.

先要有良好的学习习惯。我每天放学回来，第一件事就是把家庭作业写完，写完后，要认真、仔细地检查，看看有没有写错和漏写。

这样，正确率就很高了。检查完了，我会预习一下明天的上课内容，能写的就在书上写写，还要查资料、熟读课文。上课要认真听讲，老师提出的问题要认真思考，积极举手发言。讲错了，不要灰心，再想一想，把内容结合起来。下课后，还要把所学的知识复习复习，就会记住了。

而且，光看课本上的知识是不够的，还要看些课外美文、课外书。有许多好词、好句、好段，把他们收集起来，写作文、日记的时候就会用上它们，让作文更优美生动。在课间、写完作业的时候，也要多看书，书是知识的海洋，能让我们懂得课本上没有的知识。

这就是我的学习习惯。

Friendship is, lock, lock two people tightly together; Friendship is, candy, let two people taste the taste of happiness, friendship is priceless, and everyone needs it.

Friendship this lock, lock me with another person together, care about each other, help each other.

友谊，是把锁，把两个人紧紧锁在一起;友谊，是颗糖，让两个人尝到快乐的滋味：友谊，是无价的，每个人都需要它。

友谊这把锁，把我和另外一个人锁在一起，彼此关心，彼此帮助。

友谊，它像火红的太阳，照亮了我们成长的路线;它像甘甜的露水，为我们解渴;它又像最闪最亮的星星，每到黑夜，总在天上默默祝福着我们。

友谊，多么响亮的名字啊!它伴我们成长，伴我们玩耍.....友谊无价，是多少金钱都买不回来的。

谁都离不开友谊，珍惜吧!

又是霾!”我望着天空中灰色的霾，心灰意冷地埋怨，带上口罩。

我走出家门，行走在被雾霾包围的小路上，思考着雾霾形成的因由。

邻居王萌瑶刚从书店出来，手捧一本百科书，向我走来。我走上前去，向她道出了困解我已久的问题。

“霾污染主要人为污染源，一次和二次颗粒物的形成，霾污染的主要组成和去向。主要人为污染源是燃煤、工业和汽车尾气。秸秆燃烧是暂时和局部的污染源;扬尘和沙尘主要造成的是粗颗粒物的污染，容易重力沉降和干/湿沉积。沙尘暴有细颗粒物污染问题，但干燥且持续时间较短。从污染源直接排放的烟尘或碳黑类细颗粒物，被称为“一次颗粒物”，也较容易重力沉降和干/湿沉积。但有一部分可能通过其界面的物理化学过程和二次细颗粒物相关。

燃煤、工业和汽车尾气中的气态污染物：二氧化硫、氮氧化物和碳氢化物(大量是VOC~易挥发有机化合物)，会经历大气输送和化学过程。图中“hn”表示阳光辐射。夏日氮氧化物和碳氢在烈日下可以光化学反应，导致臭氧(O3)浓度高企和霾污染，灰色程度较轻。出国留学网二氧化硫和氮氧化物转化为硫酸滴、硫酸盐、硝酸滴和硝酸盐，是主要的吸湿性强的“二次无机细颗粒物”。碳氢化物经过物理(凝并聚合等)和化学过程，会形成可溶性“二次有机细颗粒物”。国内外大量研究成果表明，重霾污染中pm2.5的主要成分都是硫酸盐、硝酸盐和可溶性有机碳，它们是重霾污染的主凶。细颗粒物干/湿沉积效率很弱，大部分会因气流输送造成区域性污染问题。”

我点点头，望着远处的工业烟囱，陷入了无言的沉思。王萌瑶也许猜到了我的心思，继续道：

“治理雾霾最主要的方法是减少排放。目前各种化石能源的大规模使用是造成雾霾天气的最主要原因。要想从根本上解决雾霾问题，最有效的方法就是减少排放。大家想想，发电需要燃烧煤，而实际上被燃烧的煤只有不到30%被转化成了电能，其余的都被排放了。汽车、轮船等机械需要石油，同样的，发动机也只是将不足30%的石油转化成了动力，其余的也都被排放了。也就是说我们使用能源是“大手大脚”的，利用的少，排放的多。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。如果现有能源能利用70%，而排放30%的话，环境问题与能源问题会同时得到解决，人类社会也会得到可持续的发展。目前，网络上披露了一种非传统的发动机，是中国人发明的，名叫“往复式转子发动机”，有望实现人类的这一愿望。期望这种机械能早日面世。还有，就是多植树，才能有效地治理雾霾。”

我再一次的点点头，当打开家门时，我将头一转，望向灰蒙蒙的雾霾，突然看到了一束阳光穿透了雾霾的束搏。我笑了，因为不久的将来，一定会看到蓝白云蓝天。

记得书中对“雾”的描写非常美丽，作者们对它从不吝啬赞美之词，提到它我们眼前立刻浮现出虚无缥缈、人间仙境、海市蜃楼…古代诗人也钟情于它，宋代葛长庚《晓行》咏道：雨余花点满红桥，柳絮沾泥夜不消。晓雾忽无还忽有，春山如近复如途。不知什么时候开始“雾霾”出现了，虽然只多了一个字，却让人们如临大敌，避之不及。究竟什么是雾霾呢?

雾霾是雾和霾的组合词，常见于城市，在我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”。

雾霾是特定气候条件与人类活动相互作用的结果，高密度人口的经济及社会活动必然会排放大量细颗粒物(PM2。5)，一旦排放超过大气循环能力和承载度，PM2。5持续积聚就会出现大范围的雾霾。

写到这里我不禁疑惑，雾霾究竟是如何形成的?查阅了相关资料发现原来“雾霾竟与我有关”，近年来城市的汽车越来越多，排放的汽车尾气量也逐年加大，而它对城市空气中PM2。5的“贡献”竟然达到了60%之多，想想我每天上学、放学、郊游，舒服的坐在车里，不知不觉也成了制造雾霾的帮凶。而国人引以为自豪的烹饪，对PM2。5的贡献也不小，油炸、炒菜时产生的PM2。5最多，只要持续五分钟PM2。5的数值就从开始时的38微克∕立方米，迅速飙升到787微克∕立方米，而蒸、煮的烹饪方式则不然，看样子，我以后的饮食习惯要改一改了。当然形成雾霾的原因还有很多，恕不赘述。

那么雾霾有哪些危害呢?它看似温和，里面却含有各种对人体有害的细颗粒，有毒物质达20多种包括了酸、碱、盐、胺、酚等，以及尘埃、花粉、螨虫、流感病毒等，对人体呼吸系统和心血管系统的危害很严重，它导致近地层紫外线的减弱，使空气中的传染性病菌的活性增强，传染病增多。不利于我们成长，由于日照减少，紫外线照射不足，体内维生素D生成不足，对钙的吸收大大减少。还记得英国伦敦1952年的那场大雾吧!它似无形的杀手，在短短五天内就夺去了4000人的生命，在之后两个月内又夺去了8000人的生命，可见雾霾的危害也给我们敲响了警钟，我们需要的是干净的空气，健康的体魄，请不要以牺牲健康为代价来换取所谓美好生活，少开车，绿色出行，多种树，保护植物。

既然雾霾与我有关，那么治霾从我做起，保护我们赖以生存的环境吧!

由于雾霾严重，中小学生不用上课。”南京市中小学生听到这句话可能所有南京市的中小学生高兴的要命，当然一听到这个消息我也很高兴，因为我可以好好地睡上一觉了，不过忧愁还在后面嫩!如果想知道我的忧愁是什么，就到下一段去找答案吧不过庆幸的是老师每天布置的作业还蛮少的当然了!在家里的这几天也不能放松下来。嘿嘿!我正打着自己的小九九哩!放假这几天，肯定不少同学认为连放4天，先玩上三天，后学上一天，然后有两种可能：1.到最后一天又想，早上先玩会儿，晚上再学习，2.或许他们猜错了，可能放2天而已，而他们收到老师短信时，已是深夜，就没有时间复习了。所以英语听写两颗星我拿定了。老师还在网上打趣道：十年前我们抗击非典，十年后我们抗击雾霾加油!

雾霾给我带来了不少的喜和乐，同时也给我带来了更多的忧愁。明明不用上学，我却还要陪着老妈东奔西走、“颠沛流离”。这是为什么哩?因为，我老妹3周岁了，要带她去体检和打预防针哇!回想起从前坐公共汽车不要，我吐死就怪了!再加上这几天，天天雾霾，空气质量差，一不小心就会有感冒的风险。瞧!我已经开始咳嗽了。空气中又掺杂这一种不知名的怪味，可能是焚烧秸秆的味道使人的心情不好。真不知道，现在就趁这个样子了，以后我们的子孙后代该怎么办呢?

我希望大家能够一起保护环境。
