六年级关于雾霾的英语作文实用2篇 作文怎么写（精彩20篇）

Recently, the haze weather has increasingly been serious and this

phenomenon triggers the widespread concern towards air quality. In my view of

the point, the best way to improve air quality is to tax the owner of private

car.

There are reasons accounting for my view. To begin with, there is no

denying that gas emission of private car is a great evil of air pollution.

To tax the owner of private car will make some contribution to cut down gas

emission and improve air quality. Furthermore, the tax also has a great impact

on decreasing the rate of car’s increase. Those who have a plan to buy a car

will take the tax into account and some of them have to give up their plan. If a

lot of people can use public transportation instead of private cars, the air

quality will not be so rotten. In addition, taxing for private car is also a

warning of environment protection. The notion of environment protection will be

brought to public again and an increasing number of people will be awake to the

importance of air protection and environment protection and make effort to

protect it. Finally, the government can use the tax as funds of improving the

air quality, which will be a great help to raise fund.

Taking above into account, I believe that taxing the owner of private car

is the best way to improve air quality. Certainly, we can carry out other

methods to improve it at the same time, such as planting trees, developing

public transportation and so on. I advocate that all of us should take pains to

protect our environment and we will lead a better life.

Nowadays, the hazy weather frequently appears in our country. It has not only done harm to people’s health, but also affected the public transportation. Terrible accidents happen every now and then, some highways have to be shut down because of the low visibility.

Obviously, air pollution is the main factor that has resulted in the frequency of hazy weather. At the same time, smoke from burning coal and all kinds of dust are also important factors. Besides, exhaust emission from cars and buses has made the situation even worse.

So proper measures should be adopted to deal with the serious problem. To students, opportunities for outdoor sports activities should be decreased, washing faces and hands with running water after each outing is also important, and do not forget to wear a good-quality mask to protect yourself while going out.

I hope we will regain a fresh, clean and bright world soon.

We can use bamboo to knock the branches, so dates will fall down, we can eat to the dates." I listened to the idea of China pistil, happy said: "China pistil, you are so clever." She picked up a bamboo pole, want to knock the branches. Jujube is too high, however, she couldnt reach, how to do? "There is!" She stepped on a branch and two feet and a push, like a flexible monkey climbed up the tree. China pistil hugging the trunk, one hand picked up knocks on the bamboo pole to forcibly branches, see dates like raining down. So blessed and overjoyed, we run go to pick up dates. I put a jujube in your mouth, heartfelt China rui said: "China pistil, its too much of you." China pistil cheerful smiled and said: "a piece of cake." Jujube sweet filled our hearts.

Look, this is my good friend -- China pistil. A lively and cheerful, clever girl.

我有一个好朋友——华蕊。她有着一刀平的刘海，刘海下有一双炯炯有神的大眼睛，总是扑闪扑闪的。华蕊还是一个充满智慧的女孩呢。

记得去年暑假，家门口的枣树上结满了青绿色的枣子，这时的枣子是最甜的。我抱住枣树的树干用力摇晃，但是粗粗的树干纹丝不动。这时，华蕊说：“唐亦心，别白费力气了，看我的。”她捡了一些小石子，想把枣子扔下来。我看了看她，说：“这样太危险了，万一掉下来砸到人怎么办?”华蕊环顾了一下四周，似乎在寻找可以使用的工具。她的目光停在了我家阳台晾衣服的竹竿上，她说：“唐亦心，能问你妈妈要晾衣服的竹竿吗?我们可以用竹竿来敲打树枝，这样枣子就会掉下来，我们就能吃到枣子了。”我听了华蕊的想法，我开心说：“华蕊，你真是太聪明了。”她拿起竹竿，想敲打树枝。可是，枣树太高了，她够不着，怎么办?“有了!”她踩在一根树枝上，两脚使劲一蹬，像一只灵活的猴子似的爬上了树。华蕊一手抱紧树干，一手拿起竹竿用力往树枝上敲打，只见枣子宛如下雨般落了下来。我们高兴极了，跑东跑西地捡枣子。我放了一颗枣子在嘴里，由衷的对华蕊说：“华蕊，你真是太厉害了。”华蕊欢快的笑了笑，说：“小事一桩。”枣子的甜味沁入了我们的心田。

瞧，这就是我的好朋友——华蕊。一个活泼开朗，聪明伶俐的女孩。

“雾霾红色警报，南京中小学今天停课”。

“什么!哇塞!太好了!”听到这句话后，全班都沸腾了。但有的人还不相信自己的耳朵，跑到那个拿着报纸读出这令人兴奋的消息的同学那里，扒在报纸上盯着字看了好久，最后又欢呼了一声。

可是听到这消息，我一点都高兴不起来。

雾霾，名副其实，就是雾和霾的总称。但是雾和霾并不是同一种物质，它们的区别是很大的。

霾，就是灰霾，也就是空气中的一些灰尘，杂物混合在一起的浑浊现象。远远望去，就像是黄山云海般，让人误以为自己身处云端。可是霾终究和云雾不同，它的危害可是不小的。大家可以想象，如果公路上一片浑浊，交通事故是不可避免。人们吸进那些有害物质对身心健康也是一种危害。霾也分很多级，有轻微霾，轻度霾，中度霾和重度霾。在我看了新闻后，发现上海那片城市已经云雾缭绕了，却只是中度霾，可见如果是重度霾，在那一片灰蒙蒙，不见天日的场景下，会发生什么令人惊悚的事。

至于雾，它经常出现在在我们南京地区。是由空气中的水蒸气遇冷而液化成的小水滴悬浮在离地较近的空气层中而形成的，就像是地上的云，一片白茫茫。根据每次出现的雾的不同特点可以把雾分成很多种类，有辐射雾、平流雾、蒸发雾、烟雾等等。当然，它的危害也是不小的，漂流在空气中的不明物质会诱发像感冒、哮喘的症状。这可苦了最近一直感冒加咳嗽的我了。

雾和霾分开来都那么令人畏惧，这可倒好，这次咱南京惹来了雾霾!“溪月行遭雾雨霾”，大诗人苏轼遇到雾霾也要感叹一句，何况我们这些只能眼巴巴地遵循学校的安排的学生?

雾霾可谓是我们生活中一大恐怖分子，结合了雾和霾的所有特征的它对人体的伤害那是更加加剧了。我们都知道癌，那可是一种让人谈癌变色的不治之症啊。雾霾，还真能致癌--由许多灰尘、杂质、有毒颗粒、城市生活中的排气物组成的雾霾，如果它经常被人吸进体内，就会引起一些疾病，癌当然是这些疾病当中的“顶级掠食者”。

当然，雾霾的形成也离不开生活中人们的“功劳”啊!比方说现在车辆排放的尾气，工厂生产东西时流出的大量有害气体，许多大路已经灰尘漫天相关部门却从不安排人去清理。

如果人们还不重视这些，或许雾霾来临，会成为一项“自然规律”。

在此希望我亲爱的同学们及时做好保养、清洁，在家自修的同时也安心地等待雾霾逆袭后卷土回家的好消息。

针对雾霾的几点建议

科学技术是第一生产力。技术在发展过程中成为人与自然、人与社会之间进行物质、能量和信息变换的“媒介”，是变天然自然为人为自然，以及实现对社会调节、控制的手段。人类社会的每一项进步，都伴随着科学技术的进步。尤其是现代科技的突飞猛进，为社会生产力发展和人类的文明开辟 了更为广阔的空间，有力地推动了经济和社会的发展。科学技术所开拓的生产力创造了高度发达的物质文明，但对科学技术的使用不当，又引发了世界范围内极其严重的环境问题，我们在享受科学技术带来的物质财富的同时也深受其害。本文为减轻雾霾提出几点建议。

大气污染的形成不是一朝一夕，治理污染也不可能毕其功于一役。要从根本上消除重污染天气，改善空气质量，需要在制度上实现保障，从源头上进行防治，并制定长效的协同联动机制。

(一)加大综合治理力度，减少污染物排放 雾霾天气中污染物的主要来源是燃煤、燃油以及与居民生活有关的各种排放。对于燃煤源消减的关键是加强工业企业大气污染综合治理，全面整治燃煤小锅炉，逐步用高效节能环保型锅炉淘汰中小型燃煤锅炉。加快推进城市集中供热，扩大高污染燃料禁燃区范围，逐步推行“煤改气”工程建设;鼓励北方农村地区推广使用洁净煤。加快重点行业脱硫、脱硝、除尘改造的工程建设。减少燃油导致的污染物同时需要强化移动源污染防治，大城市严格限制机动车保有量，实施公交优先战略，提高公交出行比例，大力推广新能源汽车，提升燃油品质，加快石油炼制企业的升级改造，严厉打击非法生产、销售不合格油品的行为。除燃煤燃油外，污染物源还有油烟污染、秸秆燃烧等，应开展餐饮油烟污染治理，餐饮服务经营场所安装高效油烟净化设施，强化无油烟净化设施及露天烧烤的环境监管;全面推广秸秆还田、秸秆能源化利用等综合措施，加强秸秆燃烧监管。

(二)加强科普宣传工作，提高民众减排意识 大气污染不仅仅来源于工业、汽车尾气、建筑工地等，也来自于日常生活。驱散雾霾，离不开每个人的环保意识和环保行动。要积极开展多种形式的宣传教育，普及大气污染防治的科学知识，倡导文明、节约、绿色的消费方式和生活习惯，引导公众从自身做起、从点滴做起、从身边的小事做起，在全社会树立起“同呼吸、共奋斗”的行为准则，共同改善空气质量。充分发挥新闻媒体在大气环境保护中的作用，积极宣传区域大气污染联防联控的重要性、紧迫性，宣传国家采取的政策措施和取得的成效，加强舆论监督，为改善大气环境质量营造良好的氛围。

(三)加强对雾霾的监测预报预警能力研究，提高科学有效防控能力 在国家、地方相关科技计划中，加大对大气污染防治科技研发的支持力度。进一步强化气溶胶和雾霾监测分析技术研发和系统建设，完善大气成分监测体系，改进雾霾数值预报模式，有效提升雾霾天气和大气污染的监测预报预警能力;大力开展雾霾天气形成的机理研究，及城市对边界层动力热力结构的作用和对雾霾形成发展消散的影响研究。加快推进大气污染综合防治重大科技专项，开展光化学烟雾的危害性、污染机理与控制对策研究;开展区域大气复合污染控制对策体系研究。加快工业污染防治技术、工业脱硫脱硝除尘技术等的研发与示范，积极推广先进实用技术。以科学研究为依据提高大气污染的防控能力和效益。

My mother is 38 years old, but she never tells others how old she is. She says she just doesn?ˉt want them to know about it! My mother is a well-known doctor in our area. She works hard. She often gets up very early in the morning and rushes to the hospital to look after her patients. She is kind to her patients and treats them the way she treats her family. Sometimes I wonder whom she loves more, her patients or me.

My father is 40 years old. He has short hair, big eyes and a small mouth. He is my best friend.

My father is a teacher. Just like my mother, he is very busy. He doesn?ˉt have any holidays or weekends. Every morning he goes to school very early and stays with his students until late in the afternoon. It seems that he never gets tired! His students love and respect him. He always tells my mother how good it is to be a teacher, because his students make him feel young. He thinks my mother should be a teacher, too! But so far she hasn?ˉt taken his advice.

I will be a new student in my fathers school this summer. I will work harder and I hope one day I can be a good doctor like my mother.

Maryis my new friend.I got to know her only yesterday. but we like to each other at first sight. she is a tall , outspoken ,13-year-old girl. she is good at english ,and i do well in maths.we helped each other yesterday with our homework.we both like playing pingpang,and we had a match yesterday afternoon. she is easy going .and i m so glad to be her friend.

早上，当我们起床的时候，拉开窗帘，我们希望看到的是冉冉升起的太阳，温暖的阳光洒在我们的身上，欢愉，惬意，保证一天心情舒畅，吃嘛嘛香，为什么要“雾霾”_1500字作文。然而现在我们看到的是雾，是霾，是满眼的灰色，打开窗户呼吸到的不是清新的空气，而是有种异味的污染物，让我们喘不过气来，似乎整个世界对于我们来说，不是我们厌倦了我们，就是我们厌倦了世界，我想很明显是前者吧。最近，雾霾成了大众名词。还没有进入深冬，北京已经出现了几次严重雾霾。甚至我们祖国的象征——天安门也是灰蒙蒙一片，不论男女老少，听到雾霾这两个字眼，都唏嘘一片。我们的天空怎么了，为什么会变成这个样子?

“雾霾”，即“雾”与“霾”的总称。就是雾和霾的总称。但是雾和霾并不是同一种物质，它们的区别是很大的。

霾，就是灰霾，也就是空气中的一些灰尘，杂物混合在一起的浑浊现象。远远望去，就像是黄山云海般，让人误以为自己身处云端。可是霾终究和云雾不同，它的危害可是不小的。大家可以想象，如果公路上一片浑浊，交通事故是不可避免。人们吸进那些有害物质对身心健康也是一种危害。霾也分很多级，有轻微霾，轻度霾，中度霾和重度霾。

在我看了新闻后，发现上海那片城市已经云雾缭绕了，却只是中度霾，可见如果是重度霾，在那一片灰蒙蒙，不见天日的场景下，会发生什么令人惊悚的事。是由空气中的水蒸气遇冷而液化成的小水滴悬浮在离地较近的空气层中而形成的，就像是地上的云，一片白茫茫。根据每次出现的雾的不同特点可以把雾分成很多种类，有辐射雾、平流雾、蒸发雾、烟雾等等。当然，它的危害也是不小的，漂流在空气中的不明物质会诱发像感冒、哮喘的症状。

雾霾，在中国是近几年的事，可是在世界，就好比说英国，早在1952年开始，英国伦敦就出现大面积的雾霾，英国是最早工业化的国家，这也不足为奇。一开始，英国并没有重视，但是之后的市民死亡率大大高于以前，这不得不令人担忧，就这样，英国伦敦开始了长达六十多年的治理。

在今年的APEC会议期间，北京市几百家企业减少甚至停止生产，目的就是为了减少污染物的排放，说是怕为了严重雾霾出现，影响中国的国际形象，高中二年级作文《为什么要“雾霾”_1500字作文》。还有报道说，在APEC会议期间，连习近平主席都心惊胆战的。但从另一方面也说明了一个问题，中国的雾霾问题甚是严重啊！

雾霾可谓是我们生活中一大恐怖 分子，雾霾不仅会间接引发交通事故，而且还会直接导致人体虚弱，他就像是鸦 片和海洛 因一样，虽不会上瘾，但会引起呼吸系统或心血管系统的疾病。结合了雾和霾的所有特征的它对人体的伤害那是更加加剧了。我们都知道癌，那可是一种让人谈癌变色的不治之症啊。雾霾，还真能致癌--由许多灰尘、杂质、有毒颗粒、城市生活中的排气物质组成的雾霾，如果它经常被人吸进体内，就会引起一些疾病，癌当然是这些疾病当中的“顶级掠食者”。

雾霾，在有的时候是不会出现的。比如说，下雨天，霾都是固体，只是半径小，自然被雨水“冲刷”掉了；大风天气也不会出现雾霾。在雾霾出现的时候我们一定要先注意防护，无论老人小孩，还是什么人，都要尽量避免在雾霾天气外出，或者在雾霾情况见好转之后再外出，而且要购买具有特殊功能的口罩，来抵御雾霾。

当然，雾霾的形成也离不开生活中人们的“功劳”啊！比方说现在车辆排放的尾气，工厂生产东西时流出的大量有害气体，许多大路已经灰尘漫天相关部门却从不安排人去清理。每当过节，漫天的五颜六色的礼炮还有噼里啪啦的鞭炮声，但人们在点燃他们的时候，有没有想到过雾霾这件事。呃……或许不会吧，不然每年车辆的数量都还在不断增加啊。我想我们的环保观念是该加强了，如果人们还不重视这些，或许雾霾来临，会成为一项“自然规律”。

雾和霾分开来都那么令人畏惧，这可倒好，“溪月行遭雾雨霾”，大诗人苏轼遇到雾霾也要感叹一句，何况我们这些只能眼巴巴地遵循学校的安排的学生？早上不到六点钟起床，还要跑操，在一片灰色面前读书背诵，向老师反映老实的回答却是“今天的空气质量良，指数没爆表！”连历史老师都说我们是“活生生的吸尘器”。

因此，我倡议：从现在做起，从小事做起。少开车，换节能车，尽量乘坐公共交通。将雾霾赶出中国，感出全世界。我期待“环境优美，鸟语花香”的那一天。

[有关于雾霾的作文

In the happy winter holiday, I learned how to organize their own room, learned to scrambled eggs, but my biggest harvest is to spell out the several independent electronic puzzle, it has taught me can only do one thing care and patience.

I have a lot of large and small electronic puzzle elliptic electronic parts, as long as these parts according to the manual assembly model aircraft can spell out a variety of shapes. Assemble them is not an easy thing, want to have enough care and patience. I took a few parts according to the instruction manual first, but feel to spell out the model of traffic, also wont turn. And then put them down again. Second, I repeat the last spell spell dont like, repeated several times always spell is bad, I feel my patience gradually separated, just put it aside. After see together with me for my mother, and we control instruction to start, bit by bit, originally I got mixed up on the two pieces of similar parts, so spell out modeling is not spinning.

When holding a spell good the first mode shape I am happy, I know whether spell model or do other things, it is not enough to be patient, but also have enough careful.

Then I have to spell out several different kinds of models, feel very with a sense of accomplishment.

在这个愉快的寒假里，我学了如何整理自己的房间，学会了炒鸡蛋，但是我最大的收获是独立拼出好几个电子拼图，它使我懂得了只有细心和耐心才能做好一件事。

我的电子拼图有很多大大小小的椭圆形电子零件，只要将这些零件按照说明书组装就可以拼出各种形状的航模。组装它们不是一件容易的事，要有足够的细心和耐心才行。我先按说明书拿了几个零件拼，可是感觉拼出来的模型歪歪扭扭的，也不会转动。于是就把它们拆掉重新拼。第二次，我重复上次拼拼出来的也还是不像，反复几次总是拼不好，我感觉我的耐心渐渐失散，就把它丢到一边不管了。妈妈看到后说和我一起拼，于是我们对照说明书重新开始，一点一点检查，原来我把两块相似的零件搞混了，所以拼出来的模形是不会转动的。

当拿着拼好的第一个模形时我很开心，我知道不论是拼模型还是做其它事情，光有耐心是不够的，还要有足够的细心才行。

后来我又拼出了好几个各种各样的模型，感觉很有成就感。

With the development of scientific conductions, our daily life is becoming more and more convenient. But everything has both its good and bad sides, pollution has become a hot topic while the science’s building up. So the word “green” has been paid great attention among us .So do our campus.

Creating a green campus is very important to build up a wonderful atmosphere. ”Green campus ” does not only means green environment, but also means positive study atmosphere, good personal qualities and refer to that the students should be educated and have an environmental sense in their mind. What’s more, what I want to stress is that it sets goals toward the future of the world.

To bring “green campus” to its full play, effective measures should be taken. First, learning is the most important thing, which can strength our personal qualities. Second, we should take care our daily actions about manners and pick up waste papers here and there as we can do. Third , when you make mistakes or someone help you, you should say “sorry” or “thank you” to people with your sweet smile…

Green campus make us live in a soft and warm environment. So we ought to do our best to build green campus.

随着科学的发展条件、我们的日常生活变得越来越方便。但每件事都有好和坏,污染已成为一个热点话题,而科学的建立。所以“绿色”这个词已经非常关注在我们中间。我们的校园也是如此。

创建一个绿色校园是非常重要的建立一个美好的氛围。绿色校园不仅指绿色环境,但也意味着积极的学习氛围,良好的个人素质和参考,学生应该教育和环保意识在他们的脑海中。更重要的是,我想强调的是,它将对世界的未来目标。

将充分发挥“绿色校园”,必须采取有效的措施。首先,学习是最重要的,这可以增强我们的个人品质。其次,我们应该照顾我们的日常行为举止和捡垃圾论文,我们可以做。第三,当你犯错误或有人帮助你,你应该说“对不起”或“谢谢”的人与你的甜蜜的微笑…

绿色校园让我们生活在一个柔软而温暖的环境。所以我们应该尽力构建绿色校园。

2016年的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!

As the saying goes "qiu dong smog knife to kill". We can see and catch "smog" actually have bigger influence on the body, especially the high incidence of respiratory and cardiovascular and cerebrovascular diseases in the elderly group.

1. The effects on the respiratory system. Haze composition is very complicated, including hundreds of atmospheric chemistry particulate matter. Which is bad for your health mainly aerosol particles less than 10 microns in diameter, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel and car exhaust, etc, it can directly enter and adhesion in the human respiratory tract and alveoli. Especially the submicron particles are deposited on upper and lower respiratory tract and alveolar, causes the disease such as the acute rhinitis and acute bronchitis. For obstructive bronchus asthma, chronic bronchitis, emphysema and chronic respiratory diseases such as chronic obstructive pulmonary disease patients, haze weather can make the illness acute or acute exacerbation. If this kind of environment will cause lung cancer for a long time.

2. The effects on the cardiovascular system. Haze weather pollutants in the air, air pressure is low, easy to induce acute cardiovascular disease. Such as heavy fog, the moisture content is very high, if people in outdoor activities and sports, the bodys sweat is not easy to discharge, cause people bosom frowsty, increased blood pressure.

3. The fog haze weather can also result in close formation ultraviolet weakened, activity of the infectious pathogen in the air, increase of infectious diseases.

4. Reduce because of the fog the sun, ultraviolet irradiation in children is insufficient, inadequate vitamin D in the body to generate, the absorption of calcium significantly reduce, serious can cause rickets in infants, childrens growth to slow down.

5. Affect mental health. Heavy fog weather depression, due to weak light and easy to let a person produce mental laziness, depression, and pessimism, encounter something goes wrong and even easier to spin out of control.

6. Affect the traffic safety. Low vision in haze weather, visibility, air quality is poor, easy to cause traffic jams, traffic accidents.

常言道“秋冬毒雾杀人刀”。我们看得见、抓不着的“雾霾”其实对身体的影响较大，尤其是对心脑血管和呼吸系统疾病高发的老年人群体。

1.对呼吸系统的影响。霾的组成成分非常复杂，包括数百种大气化学颗粒物质。其中有害健康的主要是直径小于10微米的气溶胶粒子，如矿物颗粒物、海盐、硫酸盐、硝酸盐、有机气溶胶粒子、燃料和汽车废气等，它能直接进入并粘附在人体呼吸道和肺泡中。尤其是亚微米粒子会分别沉积于上、下呼吸道和肺泡中，引起急性鼻炎和急性支气管炎等病症。对于支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸系统疾病患者，雾霾天气可使病情急性发作或急性加重。如果长期处于这种环境还会诱发肺癌。

2.对心血管系统的影响。雾霾天气空气中污染物多，气压低，容易诱发心血管疾病的急性发作。比如雾大的时候，水汽含量非常的高，如果人们在户外活动和运动的话，人体的汗就不容易排出，造成人们胸闷、血压升高。

3.雾霾天气还可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。

4.由于雾天日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收大大减少，严重的会引起婴儿佝偻病、儿童生长减慢。

5.影响心理健康。阴沉的雾霾天气由于光线较弱及导致的低气压，容易让人产生精神懒散、情绪低落及悲观情绪，遇到不顺心的事情甚至容易失控。

6.影响交通安全。出现霾天气时，视野能见度低，空气质量差，容易引起交通阻塞，发生交通事故。

这一段时间，电视上提到了一个我从未听过的词语“雾霾”。我一直很好奇，到底什么才是雾霾天呢?我的心里一直有这样一个疑惑。

今天早上，当我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，我很奇怪。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。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……就在这时我听见爸爸说：“哎!今天又是个雾霾天气，空气不好一定要带上口罩呀!”哦!原来这就是雾霾天气呀!

吃完早点，刚出门，就发现天黄黄的，太不对劲了!原来的雾白白的，像一条白白的围巾!可今天的雾却是黄色的，好似那条围巾沾上了沙土似的。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。到了学校，同学们都在讨论这件事，这时我才真正地知道了什么叫“雾霾”。原来，所谓的雾霾就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来也严重，所以雾霾天气就越多，危害也会越大。有时会使汽车不能开，飞机不能降落。要减少雾霾天气，我们必须保护环境，多植树多种草才行呀!

导语：慈母手中线，游子身上衣，你有没有写过信给妈妈呢?以下是yuwenmi小编为大家整理的英语作文，欢迎阅读与借鉴，谢谢!

Dear mother,

I have been good at school. I often think of you when I go to bed because we always go for a walk before go to bed at home. So I miss you everyday. Do you miss me? Why don’t you call me? I’ve got a lot of things to tell you. One of the things is about foreign teacher’s daughter. Her name’s Skyler. She lives in Canada. She comes to our class to learn Chinese and English with me in my class. This afternoon, when it was art and craft class, our class were cleaning the gymnasium. And she did it with us too. So I usually talk to her when she doesn’t know what to do? But when the class is over, I always haven’t got enough time to talk to her. And I usually can’t find her. So we don’t have time to introduce to each other. But it is the first time that I have a foreign student. So I’m very happy! Mum, you often tell me, “If you are happy, I’ll be happy, too.” So you have to be happy, because I’m happy! I like you when you are happy!

In the end I wish you everything is just fine!

Yours,

Sophia.

亲爱的妈妈，

我一直在学校好。我经常在睡觉的时候想起你，因为我们总是在回家前散步。所以我每天都在想你。你想我吗?你为什么不打电话给我?我有很多事情要告诉你。其中一件事是关于外籍教师的女儿。她的名字是斯凯勒。她住在加拿大。她来我班学习汉语和英语与我在我的类。今天下午，当我们上美术课的时候，我们班正在打扫体育馆。她也和我们一起做了。所以当她不知道该怎么做时，我通常和她说话?但是当课结束的时候，我总是没有足够的时间和她说话。我通常找不到她。所以我们没有时间互相介绍。但这是我第一次有一个外国学生。所以我很高兴!妈妈，你经常告诉我，“如果你快乐，我也会快乐”，所以你必须快乐，因为我快乐!当你快乐的时候我喜欢你!

最后我希望你一切都好!

你的，

索菲亚。

这段时间，中国大部分地区普遍出现了雾霾天气这种现象。平常蓝色的天空，现在总是灰蒙蒙的，生病的人也逐渐增加。

你知道雾霾是由什么物质组成的吗?如果不知道的话，就让我来告诉你，雾霾是由什么物质组成的吧!

雾霾是由空气中的灰、硫酸、硝酸，和有机碳氧化合物子，等颗粒组成的。

就是我们平常不保护环境、滥伐森林、垃圾侵入、排放污水、毁田烧砖，才造成的这些有害颗粒。

雾霾天气尽量减少外出，外出时可戴棉质口罩来预防呼吸道受雾天“污染”。外出归来及时清洗脸部及裸露皮肤，也可清水冲洗鼻腔。雾霾天气晨练除了可以导致呼吸系统疾病亦可导致心脑血管疾病出现;雾霾天气尽量减少去人多地方，一些地方空气流通差易造成呼吸系统疾病交叉感染。平时多饮水、清淡饮食、多进食新鲜的蔬菜水果，坚强锻炼，增强免疫力。

雾霾多人体有很大的危害，这些沉淀物一旦进入我们的身体，就再也排不出我们的体外了。外出可以戴上口罩，这样可以有效防止粉尘颗粒进入体内。口罩以棉质口罩最好，因为一些人对无纺布过敏，而棉质口罩一般人都不过敏，而且易清洗。外出归来，应立即清洗面部及裸露的肌肤。

我们要保护环境、多种树、少砍树、节约每一张纸、每一滴水、每一度电。不让可恶的雾霾再次出现!

除夕夜，家家户户都要放鞭炮，但是，健康老师说∶“鞭炮会污染环境，所以，我们最好不要放鞭炮。”下面，我就给大家讲一讲鞭炮是怎样污染环境的。

晚上，哥哥争着为爷爷要鞭炮，这时候，我从家门口走了进来，对哥哥说：“鞭炮会污染环境，还有可能制造出雾霾。”哥哥说∶“我不相信。”我说：“你不相信，你就去问你妈妈。”这时候，我哥哥的妈妈正好来了，哥哥问妈妈：“妈妈，是不是鞭炮会污染环境，还可能还可能制造雾霾?”哥哥的妈妈说：“可能制造出雾霾，还可能污染环境。”哥哥说：“哦。”

我们以后不要多放鞭炮。

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

她，长着蘑菇似的头发，白里透红的脸上长着一双炯炯有神的眼睛，下面是一个高挺的鼻子。再往下看，是一张能说会道的樱桃小嘴。

她非常爱看作文书。如果你去看一看她的抽屉，你一定可以从她的抽屉里看到好几本作文书。记得上一次，学校就要进入读书时间了，而班里面总有那么几个同学忘记带书来学校看，所以此时，那些同学都着急得像热锅上的蚂蚁。这时，她就会从她的抽屉里拿出她的作文书，说：“我这里还有好几本作文书，你们都拿去看吧。”那些没带书的同学像是抓住了一把救命稻草一样，欣喜如狂地接过书，连声道谢。

她也是一个很爱帮助别人的人。她的书包里有一个“小百宝箱”，里面有许多的东西。例如：美术课要用的剪刀;语文课要用的订书机;数学课要用的固体胶……应有尽有，我们上课要用的东西多得数不清。每次大家都需要用到“小百宝箱”里的工具时，她总是毫不犹豫地给别人先用，自己最后才用。

她还是一个很尽职的人。她虽然不是一班之长，只是一个小小的组长，但是她做组长也做得非常尽职。每一次收作业，她都是第一个收齐;每一次发作业，她都发得最多。

她就是我的好朋友——夏优璇，她就是我那个爱看作文书、爱帮助人、做事非常尽职的好朋友。

With numerous technological advances,various kinds of media have been well developed. as a result,an increasing number of people are fond of purchasing goods with the help of media,such as newspapers,radio stations,Tv stations and the internet.

As we know, every coin has two sides and shopping via media is no exception. on the one hand,it saves much time,money and effort to purchase goods through media since you do not have to go to the shops in person.

Besides,you can choose what you want from an enormous variety of goods on display.On the other hand,you may be cheated sometimes by the false information and suffer a considerable loss.

As far as I am concerned, shopping via media brings great benefit to our life and our economy on the whole.At the same time, we need strengthened supervision over the information released via media.In this way,we can reap more benefits from shopping via media and reduce the possible harm to a minimum.

How I Spent My Summer Vacation The summer vacation had come round again. I was happy that I could forget about school at least for a while. Lest I fool around all through this summer vacation, I made a plan as to how to spend it. First, I thought I should go over all those things my teachers taught in the previous term so that I could have a better understanding of them. Then I thought I should take up some forms of exercise, such as walking, running rowing, to keep me physically strong. It stood to reason that with such a good plan I should make the best of my vacation time. I did, because I lived up to what I had planned.

暑假有来了。我很高兴我能忘掉学校至少一段时间。免得我我浪费了这个暑假,我做了一个计划如何度过我的暑假。首先,我认为我应该复习所有我的老师一学期教的那些东西,这样我就可以有更好的理解。然后我想我应该参加一些不同形式的运动,如散步、跑步划船、让我身体强壮。它的原看在这样的一个很好的计划,我应该好好利用我的休假。事实上我也这么 做了,因此我没有辜负了我的计划。
