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。

今天，我无意中看见了一幅图，这使我震惊了，我的心就像波涛汹涌的大海，久久不能平静。

这幅图是一个人正拿着斧头砍树，一只啄木鸟停在那个人的脖子上，那个人的头很像木头，啄木鸟说了一句令人震惊的话：这段木头里一定有虫。

这只啄木鸟说的话一语双关，点出人类愚蠢的特性。树无时无刻都在为我们释放氧气，树不仅能吸收二氧化碳，释放出氧气，还能美化环境，成片的树林冬暖夏凉，是一个避暑疗养的好地方，是我们休息渡假的首选。树具有遮荫避风、树木呼吸和蒸腾作用。而我们为什么要砍伐树木呢？为了自己的利益，相信大家都看过这样一个故事，有一个村子，为了自己利益，不停的砍伐树木，后来洪水来了，由于没有树，洪水把村子都淹没了。这多么令人伤心，人类居然去砍伐树木，没有了树木，人类就等于失去了保护伞；没有了树木，鸟儿们就失去了家；没有了树木，地球就失去了它的色彩。

人类啊！快醒醒吧！你们听，树在哭泣，鸟在哭泣，地球在哭泣！

“保护环境，人人有责。” 这句话我们从小就会说，但是，我们做到了吗?

口口声声说保护环境，人们真的做到了吗?可我看到的，不是美丽的森林，而是经砍伐后只留下一个个树桩的渺渺沙漠;不是绿色的城市，而是只有一只只铁虫在路上行驶的钢铁森林……

近年来，环境越来越恶劣。随着科技的飞速发展，人们的生活水平逐步上升，可这却致使了垃圾城市的诞生：当人们开开心心的乘着小汽车游山玩水时，可知道后面的排气管已污染了一路上的环境;当人们大方地用着一次性碗筷时，可知道这浪费了多少木材;当人们一次又一次往河里扔垃圾时，可知道自己正在亲手制造一条垃圾河;当……

让我们来看看自己种下的种子造成了哪些后果吧：据统计，目前我国沙漠及沙漠化土地共149.6万平方公里，现在仍以平均每年增加100多平方公里的速度发展，甚至一向与沙漠无缘的我国南方，也出现成片的沙荒地。如东北长白山区，森林覆盖率比建国初期减少了约18%。目前，砍伐量已超过生产量的50%以上，我国的森林覆盖率仅为13.98%，居世界第123位。

大地之上，点点污痕这是人们所给予它的回报;地球受到了无尽地折磨，它曾经无私地为人类提供保障，得到的却是数不清的伤害。这一切都是拜人们所赐!

我心中的梦，无比的简单，我只是希望蓝天能一直蔚蓝，小河能一直清澈，大地能一直绿意生晖，我要从我们身边的点滴做起，从自身做起，随手捡起丢在地下的纸片，不去污染小河的面容，不要升起那一缕废气，让我们共同建设，这个梦想中的绿色中国吧!

Long long ago, there were many trees in the mountain, in order to make contribution to the development of the economic, the promising value of the trees have incurred a large-scale deforestation. A lot of trees were hewed, and the mountain have been divested of its primitive habituation, which were contributed by the trees.

Barren topsoil were subsequently exposed, led the ecological balance lost. Ever since then, people live around the mountains have suffered from natural disasters, flooding or drought. However, the situation stopped deteriorating when an old sage saw that with his grandson. They decided to persuade people to plant trees to ameliorate the ecological environment.

导语：吸烟有害健康，我们一个远离它，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!

A survey about smokers in a middle school tells that although 90% of all students never smoke, 3% of them often smoke and 7% sometimes do. In other words, 10% of the students smoke. That s terrible.

As we know, smoking is harmful to our health. Every year, thousands of people lose their lives because of it. Smoking not only does harm to your health, but also wastes money. Because, a fire may be caused by cigarette ends. It s a pity to learn that one ends in death by smoking.

In all, smoking is so dangerous that we should keep away from it.

参考翻译

一项关于中学生吸烟的调查显示，尽管90%的学生从不吸烟，其中有3%的人经常吸烟，有时有7%的人吸烟。也就是说，10%的学生吸烟。那太可怕了。

众所周知，吸烟有害健康。每年都有成千上万的人因此而失去生命。吸烟不仅有害健康，而且浪费金钱。因为，火灾可能是由烟头引起的。得知一个人死于吸烟是令人遗憾的。

总之，吸烟是如此危险，我们应该远离它。

As we all know, there are many people smoking, although everyone knows smoking is harmful to us. Giving up smoking is not easy but addicted to it is quite easy, that’s why there are more and more people smoking. Smoking and passive smoking is risk factor that leads to various diseases. It has become world’s top 8 causes of death. More than 90% of lung cancer caused by smoking and lung cancer rates of smokers are 18 times over the non-smokers. Besides, smoking also causes angiocardiopathy, digestive system disease, oral disease and so on. In addition, passive smoking causes great concern in recent years. People have known that passive smoking also do great harm to human, too. Therefore, many countries and regions prohibit people from smoking in public zones, in order to reduce the harm of secondhand smoke. From my point of view, the best way to keep healthy is giving up smoke, for smoker’s own good as well as for others.

众所周知，即使人们都知道吸烟有害健康，但现在依然有很多人吸烟。吸烟容易戒烟难，这就是为什么烟民越来越多的原因。吸烟以及吸二手烟都是导致多种疾病的危险因子，烟草已经成为全球第八大死因。超过90%的肺癌是由吸烟导致的，吸烟者患肺癌的几率是非吸烟者的18倍之多。此外，吸烟也会导致心血管病、消化系统疾病、口腔疾病等。此外，吸二手烟在近些年也引起了人们很多的关注，它也会对人体造成危害。因此，为了减少二手烟伤害，许多国家和地区都禁止人们在公共场所吸烟。我认为，为了自己也为了他人的健康着想，保持健康的最好办法就是戒烟。

地球是我们共同的家园，是我们共同的母亲，保护地球是我们的责任，我们应该来保护我们美丽的家园，不能让它受到破坏!”这是大家的心声，现在我们拥有许多美好的东西：豪华而有朝气的房子、又平又宽的公路、一片绿油油的田野、宽大的体育馆，但这又有什么用呢?人们一次又一次地砍伐树木，使美丽的森林变成光秃秃的了，用来做筷子、椅子、桌子、铅笔、床……在那附近的城市可能会遭到沙尘暴或者台风暴雨的袭击。所以，我们不要滥砍乱伐，过分的砍树，不止大自然受到破坏，还有许多小动物们也失去了温暖的家，我们要爱护大自然，给小动物们一个温暖的家!

我曾看过一个电视节目叫做《科学世界》，这个电视节目叙述的是科学家推测500年后的北美洲海洋，因为地壳运动的变化，陆地和陆地互相碰合，造成海洋被封锁，海水不能流动，那里因为天气炎热海水才容易蒸发得快，过不了多久全部的海水被蒸发了，变成了干旱的土地，一些动物因环境的变化慢慢地进化成了另一种形状，就连性格也改变了，一只性格温柔的松鼠竟变成了性格凶猛狡猾的松鼠了……

我还看过一本新编的《十万个为什么》，里面说：“自古以来，古人们都会节约用木头，即使他们去砍树来烧饭做菜也会利用树木，他们只是砍掉一棵树的顶端部，使树木不会断绝生机，让它们还会继续生长，这样就不会毁坏大自然。可是到20世纪90年代初,全球本来100%的树木却一瞬间用去了25%的树木,那个时候还剩75%的树木，从那起，人们就开始疯狂砍伐树木，弄得树木越来越少。美国和英国每天砍伐树木约80亩，这样一来没过多久，全球的树木要全被砍光了!”

听了我那么多的介绍， 同学们!这些种种事情，难道还不能给我们教训与启示吗?哦，还有全世界的叔叔阿姨、爷爷奶奶、哥哥姐姐、弟弟妹妹、伯伯你们都知道应当怎么保护大自然了吗?大自然中还有更多需要我们去保护的地方，不仅是大自然需要我们的保护，环境也需要我们来保护!让我们一起来保护大自然吧!

在现实生活当中，有许多贪图利益的人们，只为自己的利益，而不为别人打算，例如：

人们乱砍树木，让一大片的绿洲成片的倒下，让砍伐树木的人们拿去卖了钱，让小动物们无家可归并且失业。本来，这片森林是一个小动物们赖以生存的地方，森林是动物与植物和谐相处相互依靠的栖息地，他们在这里蹦着。跳着。唱着歌。跳着舞，让森林各个角落都充满了欢声笑语。

森林在释放氧气，净化环境，为人们做出巨大的贡献，可是人类在干什么呢?他们在砍伐树木，让肥沃的土地沙漠化，最终变成荒无人烟的沙漠，这是多么愚蠢的事啊!

我听过一个故事，它是这样的：

一天，森林中的啄木鸟医生，在为他的患者大树们检查身体，默默的在为森林做着贡献，在他回家的时候，一个余味无知的人类在砍伐树木，大树一棵棵倒下。看到这个情景，医生不由自主的飞到他的肩膀上，盯着他的脑袋，嘴里发出感叹：这段树木里一定有虫。原来啄木鸟医生把他的脑袋当成一段树木了，这说明了什麽、充分说明了人类的无知，树木对人类多麽重要啊!它为人类提供氧气，保护着土地，有着巨大的贡献。

我们要保护地球。保护地球的生态环境。让地球更好地造福于我们的子孙后代吧!

When I first set my eyes on a father and his daughter, I heard the father ask about his daughters school life. To my surprise, the girl told his father to read her blog so that he can get what he wants.

Now, the Internet has been playing an increasingly important role in our day-to-day life. It has influenced us a lot, especially on our interpersonal communication.

For one thing, the Internet makes the interpersonal communication more convenient. We can contact with each other no matter when and where. The Internet makes full use of time and space. What’s more, we can also share our daily life and knowledge through QQ, MSN, and blog with others. For another thing, the Internet speeds up our interpersonal communication. We can save time to do our work. However, the Internet also brings about many problems, such as safety problems, cheating and so on. Many people spend too much time on the Internet, and they dont have time to interact with person in real life, which result in the absence of ability in communication in reality.

It has both advantages and disadvantages to interact through the Internet. We can get to the problem in our work and study. Last but not lest, we have to talk with people and develop our ability to communicate in reality.

Computer games are good to our life in some fields~Such as it can help us relax ourselves and maybe wo can have fun in the games!Someone even says they find true themselves in the game,they can be the best in the games!I think computer games are the production in the information time and of course are popular with the youth!

But playing more may not be good to us!Someone will spend more time and money in them!Its a waste I think!Its bad for our eyes and some scientits said it can make people be fool~

In a word,playing computer games isnt wrong but wed better contorl ourselves not to lose yourslves!Appropriate game is a pleasure but indulge in it may hurt you

Traffic Safety(交通安全)

Traffic safety is everybodys business. Records show that every year a lot of people die in traffic accidents. Some of the accidents are due to mechanical problems. However, most of them are the results of careless and reckless driving, and could be avoided. A lot of people disregard traffic signals and rules. They drive regardless of speed limits, run through red lights, drive in the wrong direction, talk and laugh while driving, and turn as they wish without giving signals. They dont slow down while approaching crossroads. So many people violate traffic regulations that we cannot put too much emphasis on the importance of traffic safety. Only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

交通安全人人有责。纪录显示每年有许多人死于车祸。有些车祸是由于机械问题。然而大部分车祸都是疏忽而卤莽驾驶的结果，并且可以避免的。许多人无视于交通号志和规则。他们驾驶时不管车速、闯红灯、逆向行驶、开车时交谈，并且不打灯号就任意转弯。他们接近十字路口时不减速。如此多的人违犯交通规则以致于我们再怎么样强调交通安全的重要性也不为过。唯有当每个人皆认为交通安全是众人的事时，我们在路上开车、在行人道上走路才安全

现在，我们的地球母亲正在伤心的流着眼泪！养育我们的母亲为何流眼泪呢？

我想，聪明的你应该知道我们的地球妈妈为什么流泪了！

没错！她正在为我们的不断的砍伐树木。而感到伤心，难过。一座座的高楼大厦围绕在我们身边。虽然起房不是什么对环境有害的事。但是，我们把以前耕地种菜的地方用来起房，我们怎么还有绿油油的青菜可吃？

我们为了利益而砍伐树木。虽然树木能够当家具用。但，要知道，一棵树木只要要种到7，8年才算长大。而且树木不但能够吸收二氧化痰，还能环保。改善生态平衡！

由此看来，树木能够让地球妈妈开心的宝贝！世上万物都是地球妈妈的宝贝，但我们也不要随意破坏！

我们为了能够让地球母亲不要难过，伤心。那我们就应该不要砍伐树木！

在一个荒无人烟的土地上，有一棵快枯死的大树，它的“外衣”——树皮裂开了许多，正在一块块地往下掉，树水分全部被蒸发了，叶子又干又黄，仅有的几片树叶也没有生机，它很伤心，正在痛哭，天上的白云发现了它，便轻声细语大问它：“大树，你为什么哭得那么伤心?难道你生活的不快乐吗?轻轻的河水浇灌你，柔和的阳光沐浴你，患有许多同伴陪伴你……

大树止住哭声，叹了口气，皱起眉头委屈的说：“我哪里快乐，你看我，这副样子，要和以前比那是差得很远，过去我有挺拔的身躯坚韧的?外衣?，茂密的?头发?，身体充满水分，不仅如此还有许多小鸟为我捉虫，使我非常健康。现在，由于人们乱砍伐树木，鸟类也遭到了大量捕杀，这就使许多虫子猖狂起来，我的同伴：桐树、白桦、红松，已经砍伐走了;以前美丽活泼的小溪，也已经浑浊不清，小鱼小虾都濒临死亡”。白云听到说：“我们家也是，现在我们家的孩子也在生病都是那些人们造成的污染。”

朋友们，你们听完大树和白云的诉说：“我们不仅需要他健康的生存，还要他滋润我们的生活，让我们找到生活的快乐。

现在我们开始行吧!!!让我们从小事做起，从生活中的一点一滴做起。

人人都喜欢优美舒适的身活。可是有些人却乱砍伐树木，破坏森林。这不，沙尘暴天气多次“光顾”北京。

那天，沙尘暴有袭击了北京。妈妈去了一趟北京。妈妈回来后，有气无力地说：‘那里的房顶树叶和刚刚钻出来的嫩芽都被一层细沙盖住了过了一会儿细沙就弥漫在整个天空中突然一阵强风刮过来卷起了地上的沙尘打在脸上还有点痛嘴里也钻进了沙子一咬牙齿就会发出咯吱咯吱的响声真难受这一定是他们乱砍伐树木造成的后果。’妈妈满脸怨恨地说。马上到7点了，我开开电视，和妈妈一起看了新闻联播，里面有一个报道：半个世纪以来，北京沙尘暴发生次数急速上升，沙漠化以每年2460平方公里的速度在扩展，这是多么惊人的数字呀！

小朋友们，通过这里的数据，你们可要告诉你们的大人，千万千万可不要再乱砍伐树木了哟！

With the development of science , more and more people are confused that whether it is good or bad to make robort. Are roborts going to take place of human beings.

Every coin has two side. Robort can be good to our society and life. At the same time,it also have some bad effect on our life.In my opinion, the advantages of robort are much more than the disadvantage of roborts.

First, roborts make our life more convenient. We can do many thing that we didnt have the ability to do in the past by using roborts.That makes our life more effective.

Second, roborts can be used in industry produce. Factories can reduce the cost of prodution by using roborts. Roborts do not need to eat and they will not be ill. Thats very good for producing goods.

Third,roborts can save more people when disaster happens. Because they cant feel pain and they can save more people without feeling tired.

In a word, the world is changing .We should also change our thought to accept roborts to become part of our life . That can make our life more colorful.

随着科技的发展，越来越多的人都感到困惑，是好是坏机器人。是机器人将取代人类。

每个硬币都有两面。机器人可以很好的为我们的社会和生活。同时，它对我们的生活也有不好的影响。在我看来，对机器人的优点远大于缺点的机器人。

首先，机器人使得我们的生活更方便。我们能做的，我们没有做过去用机器人的能力，很多事情，使我们的生活更有效。

其次，机器人可以用于工业生产。工厂可以通过降低生产成本的机器人。机器人不需要吃饭，他们会不会生病。这是非常好的生产商品。

第三，机器人可以挽救更多的人，当灾难发生时。因为他们不能感到痛苦，他们可以拯救更多的人而不觉得累。

总之，世界在变化，我们也应该改变我们的思想，接受机器人成为我们生活的一部分。这可以使我们的生活更加丰富多彩。

The Dangers of the Fake Product

“Shan Zhai” is the new words to express fake products, people use it to express the highly imitated products, some manufacturers produce the Shan Zhai products to make great profit, but it is so unfair to the customers, they pay so much money in the purpose of buying the genius stuff instead of the fake products. Fake products not only cheats people’s money, but also brings people dangers. Such as the medicine, if people buy the fake one, once they eat it, they will feel uncomfortable and get the illness, the most terrible situation is that they will kill themselves. Fake product is so harmful, though the government has taken some action to ban it, still people sold it, it is the temptation of profit that makes people sold it. What if their relatives have bought the products, so in order to keep people healthy, fake products should be banned.

“山寨”是用来表达伪劣产品的新代言词，人们使用它来表达高仿产品，一些生产商生产山寨产品以此来获取巨大的利润，但是这对于顾客来讲是不公平的，他们花费了这么多的钱，只为了买到真的产品而不是假的产品。伪劣产品不仅欺骗了人们的钱，而且给人们带来了危害。比如药，如果人们买到伪劣的，一旦服用，就会感到不舒服，生病，最严重的情形就是因此失去生命。伪劣产品是如此的有害，虽然政府已经采取了一些措施来禁止售卖，但是仍然有人兜售，他们是抵挡不住金钱的诱惑。如果他们的亲戚买了这些产品，会怎样呢，因此为了人们的健康，不要再卖伪劣产品了。

Li Hua spent too much time playing computer games and he fell behind others。 As a good friend of his， I must do something to help him。

Firstly， I think it’s very important for him to learn lessons well。 He should spend most of his time on his study instead of computer games。 Secondly， I must tell him that playing computer games too much is bad for his health， especially for his eyes。 So he must give it up。 I can play more sports with him after school。 Maybe he will become more interested in sports than computer games。 And then I‘ll ask him to concentrate more on his study。 Of course， I will try my best to help him with all his subjects。 I think I can do it in many fun ways and let him find much fun in studying。 At the same time， I’ll ask both his parents and our teachers to help him， too。 If I try these， I‘m sure he will make great progress soon。
