我们生活的地球正在迅速恶化，我们不得不注意一下自己的生活环境有没有对大自然造成危害，大家必须必须别乱丢杂物，特别是那些污染严重的垃圾，比如废电池，因为一节废电池中所含的重金属，如果流到清洁的水中，它造成的污染是非常厉害的，其次要尽量节约纸张、铅笔等树木造的物品，因为浪费了这些东西就是毁灭森林。还要尽量少用一次性饭盒、筷子和塑料袋等物品，以免造成不必要的浪费和减少垃圾的产生。

还有一些小建议：走时要随手关总开关，以免电器过热爆炸，浪费钱又浪费电，要节约用水，刷牙时要关紧水龙头，洗菜水可以淘米，淘米水可以浇花，洗衣水可以拖地，如此就可以减少一些浪费了。不要随意捕杀野生动物，一二级保护动物是绝对不能杀的，但也别捕杀青蛙等常见动物，因为青蛙为我们吃掉1.5万的虫子，而且大部分是害虫。有些人经常不以为是，依旧我行我素，所以我们要尽量少吃野生动物，导致他们野生动物销售额下降，不再捕杀野生动物。

关于人类与环境的英语作文 Human and the Environment

Last weekend, I wanted to swim in the river that I usually wen in the childhood. When I went there, I was shock. The river is no longer like before. It was full of rubbish. It seemed that the rubbish is from the villagers themselves. In order to put the rubbish nearer, they put all of them into the river. Not only the water is not clean any more, the river also smelt bad. I real touched. Why human and the environment couldn’t live harmonious? Long time ago, they could get along with each other. Why not now? People have to stop their behavior to harm the environment. Otherwise, it would cause destruction to both sides.

上周末，我想去我小时候经常去的那条河里游泳。当我去那里的时候，我很震惊。河水再也不像以前那样了。河里面到处都是垃圾。似乎这些垃圾都是村民丢的。为 了不走那么远丢垃圾，他们把垃圾都丢到河里了。水不仅仅不干净还会散发出臭味。我真的触动了。为什么人类和环境不能和谐地相处呢？很久以前，他们可以好好 相处。为什么现在不可以了呢？人们必须停止他们伤害环境的行为。否则，最后会是两败俱伤。

1.1词汇方面

如果把写英语作文比作建楼房的话，英语词汇在英语写作中起着砖、瓦的作用，是句子的最基本的组成部分，所以词汇是我们高中英语教学中的重点，单词听写是课堂教学必不可少的一个环节，但学生的词汇量毕竟有限，遇到问题时，便会用汉语词汇去补充英语词汇的空缺。

例如：交通十分繁忙。误：The traffic is busy. 正：The traffic is heavy.

她和一位教授结婚了。误：She married with a professor.

正：She married a professor.

英语词语的词义往往比较复杂，并和汉语有着一定区别。这种不同就会会导致学生仅把写作当作一词一句的翻译来做，结果是事倍功半。

1.2语法方面

英语中难点就是时态，语态的掌握。英语中常用时态共十六种，语态分为主动语态与被动语态，语气有陈述语气与虚拟语气之分。不同的时态有它特有的句法结构。如现在进行时态使用be＋v－ing形式来表示。现在完成时则用have／has ＋p．p来表示。一般将来时则用shall／will／be going to＋v来表示。英语中时间意义的表达是通过动词的时和体来加以反映，而汉语中不存在时、体等，汉语则依靠表示时间的副词（如“曾经”、“正在”、“已经”、“将要”）作状语，或利用虚词“了”、“着”、“过”等作补语这一语法手段来体现，动词本身无任何变化。在英语中，“already”和“ever”常常用在完成时态之中，不能与表示过去的时间状语连用。学生常常把上述句子错译成“Yesterday I have been to the park．”“Five years ago，they have known each other．”又如在英语中，我们常常用否定前置来

这里有几片茂密的森林，森林之间有一条清澈的小河，就就像一条蓝色的绸带。

可是 ，渐渐地周围的森林被砍伐的所剩无几了，小河中原来清澈的河水也不见了踪影，却变成了臭气熏天的臭水沟。这都因为人类无情的破坏！小燕子对小鱼说：“人类 太可恶了，不仅把地球母亲弄得千疮百孔，还把我们赖以生存的家园给破坏了！“小鱼说道：是呀，因为人类 ，现在的水质变得越来越差了，我简直活不下去了。还因为人类工厂的废气排放，让我再也看不到湛蓝的天空了！”

当我看到了这个情景，我攥紧拳头，心里又伤心又愤怒，我想：那些人们有良心吗?请你们珍惜地球吧！

The school, is the world of knowledge, the school, is our friends paradise, it provides us a healthy and beautiful learning environment.

Let me introduce our school. Once inside the school gate, two rows of straight palm trees stand on each side, like two young pioneers, guarding the campus. Two beautiful little gardens behind them, the flowers in them are beautiful. The willow tree in the playground, graceful, the spring comes, she was combing her hair, as if in waved to us, one side of the Holly and poplar have also show their new clothes. The pleasant scenery of the campus has created a comfortable learning environment for us to grow healthy and lively.

However, there are a few students behavior, let we see what we dont want to see: the playground, there will always leave some on the corridor, corridor confetti and small bags; On the lawn, the green belt occasionally discovers the deep footprints left by the students. Others have turned the desks in the classroom into "cat faces"; Not to save water, to lose precious water, and to make the flower bed a playground...

In our daily life, the living environment is very important. But in daily life people in protecting the environment is not very seriously.

In order to let our beautiful environment, no hurt. There are many old people to clean street, greening lawn. They finished a day early out, to the motherland green environment at all costs. But as fate would have it, those who do not care for the environment but also to destroy, we have to provide for those who do not care for the environment and ideological work, let them early day break habits.

On the way we go to school, there is also a team the many classmates litter waste. For example: some students throw snack bags at the school gate, and the classmate throw like folded paper airplane, even along the wall into the school. Their actions again and again to affect not only school, to be on duty every morning classmates brought a lot of trouble.

Meeting in the school, the teacher again and again asked, to persuade, but some classmate dont persuaded, but continue to damage the environment, shorten the life of the earth.

Once, the school organization we 2, grade 6 students to pick them pick up white trash park lawn. Before departure, I thought to myself, common tour to play in the park, think there are clean. Today to pick up white trash, should be few, pick up must be very easy.

But when I walk there, looked down, I was shocked. There are a lot of rubbish on the ground. Waste paper, cigarette butts, plastic bags, etc. These are everywhere, a green lawn, under the destruction of tourists has become a piece of environmental pollution, this is how serious environmental problems.

In the face of the lawn, make us angry, try to eliminate those rubbish. After 100 minutes of our labor, labor, and the grass is finally back to the original beautiful, famous flowers qi yuan contend in fragance and fascination. We can not help but sigh: originally the earth also is very beautiful!

在我们日常生活中 ,生活环境是十分重要的.但在日常生活中人们在保护环境上并不十分重视.

为了能让我们的环境优美,不受到伤害.有许多老人来打扫大街,绿化草坪.他们每天早出完归,为了祖国的绿化环境不惜一切代价。但那些不爱护环境的人偏偏还要去破坏，我们一定要为不爱护环境的人做好思想工作，让他们早一日改掉恶习。

在我们上学的路上，也有许队多同学乱丢废弃物。比如说：有的同学把小吃袋扔在校门口外，还有的同学把叠好的纸飞机随意乱扔，甚至顺着墙扔进学校.他们的这些行为不但一次又一地影响着学校，还给每天早晨做值日的同学带来了很大麻烦。

在校会上，老师一次又一次叮嘱、说服，但有些同学并不听劝，而是继续破坏环境，缩短地球的寿命。

有一次，学校组织我们2—6年级同学到采俸公园的草坪上捡白色垃圾。在出发之前，我心里想，平常到采风公园玩的时候，觉得那里比较干净。今天去捡白色垃圾，应该很少，捡起来一定很轻松吧。

但当我走道那里，低头一看的时候，却把我惊呆了。地上有许多垃圾。废纸、烟头、塑料袋等。这些到处都是，一块绿色的草坪，在游人的破坏下成了一片环境污染地，这是多么严重的环境问题。

面对这块草坪，使我们愤怒不已，努力去消除那些垃圾。经过我们100分钟的劳动，草坪终于恢复到了最初的美丽，名花齐葩争芳斗艳。我们不禁感叹：原来地球也是很美的呀!

Protection of EnvironmentThere are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

Some people think that human needs for farmland, housing, and industry are more important than saving land for endangered animals. Do you agree or disagree with this point of view? Why or why not? Use specific reasons and examples to support your answer.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is "Yes." It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will affect all the other parts. For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies which migrate from Canada to Mexico. Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.The quality of our life has been changed. America used to be covered with giant trees. Now we have to visit them in one small park. Rainforests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

Improve our environment

Good environment can make people feel happy. To improve the environment means to qualify our life . What should we do to improve our environment ?

We should plant more trees . And we should prevent those factories from pouring waste water into rivers , lakes and fields . Whenever we see litter on the ground , we should pick it up and throw it into a dustbin . Don’t spit in public places . Don’t draw on public walls . It’s our duty to keep our earth clean and tidy .

良好的环境能使人觉得愉快。改善环境，使我们的生活。我们应该做什么来改善我们的环境?

我们应该种更多的树。我们应该阻止那些工厂废水流入河流，湖泊和田野。每当我们看到地上的垃圾，我们应该把它捡起来扔到垃圾桶。不要在公共场所吐痰。不要在公共墙上画。这是我们的职责，保持地球的干净和整洁的。

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why?——Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial production and increased consumption of goods. Bedsides, the use of chemical substances in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition?More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

In the last several decades, our earth has been extremely polluted, such as

air pollution, water pollution, noise pollution and so on. In recent years, the

extreme weather becomes more and more frequent. Winter gets colder and summer

becomes hotter and it rains more frequently. All of these warn us that

protecting the environment is a serious and emergent event. As our general

people, we should build proper lifestyle. We should pay attention to water and

light saving. When we go out, we should firstly choose the public

transportation. The most important is that we must realize that we can do a lot

of things to protect our environment. Its our duty to make our home better.

Let’s change from ourselves.

Protect the environment, is to protect human survival environment, make the earth from pollution. Environmental protection consciousness, starts from me, starts from dribs and drabs, start with a small paper scraps.

The classmates you know? "Environmental protection" this two word write very easy, but it is very difficult to do. If we dont do "environmental protection", then maybe in five years later, maybe after ten years, maybe in the future one day, and what will happen to our world? May be a grey day, you can see garbage everywhere, every some time will come a sandstorm, would come so many people unable to imagine...

I really did not dare to imagine again, write down again, this really is terrible. But now how many people are really in the environmental protection? You see, every trash can next to have full of rubbish. Although the rubbish is only one step away from the trash, but around and no one will put the rubbish into the trashcan, you both do turn a blind eye to it; How many trees have been cut down, sent to the factory, to make a one-off chopsticks, for those who covet convenient use, make it match, make paper towel... And then to the market to sell. I think if these items will talk, they would have said such a sentence: "wake up! Dont damage the environment again, dont destroy our home again, you will regret later. Dont you dont want to be a family? Dont want the earth? If you want these things, then began to protect us, and begin to protect your dribs and drabs around!"

Now you may have a little regret! Maybe thinking about a variety of ways to save the world, to save our home! Actually very simple, we just have to start from around things. See waste paper fell to the ground just bend over to pick it up; See saplings fall down, just a few friends together, righting it together, together to help it grow; Protect wildlife, covet them delicious meat, that no longer will they brutally skinned meat; To open a small speech, called on people to protect the environment, protect the people and objects around. Every little bit, starts from the minor matter, starts from the side, hard for the earth.

Let us act, protect the environment, do a good job in environmental protection. Dont let the noise of the earths environment is damaged again!

保护环境，就是保护人类生存的环境，使地球不受到污染。环保意识，从我做起，从点点滴滴做起，从一张小纸屑开始做起。

同学们你们知道吗?“环保”这两个字写起来十分容易，但是做起来却十分的困难。如果我们不做到“环保”，那么也许在五年后，也许在十年后，也许就在未来的某一天，我们的世界又将会变成什么样子的呢?可能是天灰蒙蒙的，到处都可以看到垃圾，每隔三两天就会来一次沙尘暴，就会来许许多多人们无发想象的事情……

我真的不敢再想象下去、再写下去了，这真的太可怕了。但是如今又有多少的人是真真正正地在环保呢?你们看，每个垃圾桶旁都有数不胜数的垃圾。尽管这些垃圾离垃圾桶只有一步之遥，但是四周围来来往往的人没有一个人会将这些垃圾投入垃圾桶内，大家对它都不约而同的做到视而不见;有多少棵树在被砍伐，送往工厂，做成一次性筷子，给那些贪图方便的人使用，做成火柴，做成纸巾……然后到市集上去卖。我想如果这些物品会说话，他们一定会说这么一句话:“醒醒吧!不要再破坏环境了，不要再破坏自己的家园了，你们以后一定会追悔莫及的。难道你们不想要家了吗?不想要地球了吗?如果你还想要这些东西的话，那就请你们开始保护我们，开始保护你们身边的点点滴滴吧!”

现在大家也许有点后悔了吧!也许在想各种各样的方法来挽救这个世界，来挽救我们的家园吧!其实很简单，我们只需从身边的小事做起。看到有废纸掉在地上就弯腰将它捡起;看到小树苗倒了，就几个小伙伴合力，一起将它扶正，一起帮助它成长;保护野生动物，不再贪图它们那鲜美的肉，将它们残忍地剥皮吃肉;开一次小小的演讲会，呼吁人们保护环境，保护身边的人和物。一点一滴，从小事做起，从身边做起，为地球而努力。

让我们行动起来，保护环境，做好环保。不要让地球的环境再次受到破坏了!

THE citys meteorological observatory issued a white warning sign Thursday indicating the citys weather could be influenced by a tropical sand storm in the next two days.

The meteorological observatory in Beijing said the storm could hit the city.

"Coastal areas in eastern Beijing could have winds as strong as force 8," the observatory said.

The air quality will become rather terrible with the sand storm.

The wind and sand will cause the city pulluted.

Terrible sand storm!

【参考译文】

星期四，该市气象台发布了一个白色预警信号，表明该城市的天气可能在未来两天受到热带沙尘暴的影响。

北京气象台说，风暴可能袭击该市。

天文台说：“北京东部沿海地区的风力可能比8级强。”。

沙尘暴将使空气质量变得相当糟糕。

风和沙将导致城市污染。

可怕的沙尘暴!

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

我们的环境污染我们现在的生活比以前好得多，但环境跟以前简直就不能比。以前的空气清香并掺和着花草的芳香，河水清澈见底。而现在呢?汽车排出的废气和工业废气相当多，河水臭气直出。我们大家为了过上好生活，都买汽车，但车主们有没有想过这样的量使用汽车的后果。

有些地方之间的距离非常近，但车主们不想跑，就直接开汽车。假如一辆汽车一天排放一千克废气，那么中国每天大约有几千万辆汽车在行驶，那么一天就要排放几千万千克的废气。这个数目仅显示一天一千克的废气排放量和仅计算中国的废气排放情况。工厂的污染更严重，水和空气都要被污染。大量的废水排入大海和河流之中，以致大量的鱼虾、水中植物死亡和大量的水资源被污染。

我们地球上的资源也在一天一天的减少。大量可回收的品中只有3﹪是被回收并再生的。许多白色垃圾造成了白色污染。我心中的家园是和以前差不多的，可是这是很难挽回的。为了我么大家共同生活了几千万年的蓝色星球？——地球的美好未来而努力吧！

一：环境污染的根源

在十年前的中国，大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样，看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产，燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝，随着中国经济的迅速发展，人们生活水平的不断提高，人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题，其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬，专家们各有其立场，但对于普通百姓来说，全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖，海平面上升，冰川融化，动植物灭亡的问题，人们大多数是在电视新闻或报刊杂志上看到，恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题，人们开始关注更多的便是最近发生在北京，广州，武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康，更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象，国外专家学者很多年前便开始研究。

那么何为灰霾？灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物（PM2.5）和臭氧()、二氧化氮（）、二氧化硫（）、挥发性有机物（）等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关，还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种，直径小于2.5微米的颗粒物（PM2.5）和直径小于10微米的颗粒物（PM10）。虽然两种形式的颗粒物都对人类健康有极大的危害，PM2.5被普遍认为是更危险的，因为它的体积小，大约只有人类头发宽度的1/30。人们在呼吸时，PM2.5可以进入人类肺组织深处，甚至进入血液，造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此，PM2.5可以传播的更远，停留在空气的时间越长，影响更大的人口。PM2.5和PM10的主要来源包括机动车，电厂和其他工业源，以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合，可以在城市或农村地区天空一片阴霾，而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因，像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围，当地空气干燥，白天阳光充足。到了晚上，地表面冷却很快。地面附近的空气变冷，而上层空气都比较热，形成逆温。北京市位于华北平原的西北边缘，背靠太行山余脉和燕山山脉，面对辽阔的华北平原，东南距渤海约150公里, 地处暖温带半湿润地区，气候属于暖温带半湿润大陆性季风气候,四季分明，春季多风和沙尘，夏季炎热多雨，秋季晴朗干燥，冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远，周围地形如盆地，集热容易散热难，河湖多、晚上水汽多，城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市，而且城市海拔较低，周围至少有一面是高地，都分布在低于南北纬50度的地方。这些地区夏季阳光明媚，天气温暖干燥。在城市的盆地地区，逆温现象十分普遍。夏季的阳光使地面温度升高，城市街道和建筑物迅速升温，与炎热的物体表面接触的空气温度升高。通过对流空气向上运动，但它却不能穿透逆温层，因为上面的空气温度更暖且密度更小。空气聚集，但连续的对流形成了垂直的循环，使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下，通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集，大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响，学者称它为街谷模型。随着城市化的加速，城市及城市周边的自然生态系统逐渐被人工生态系统取代，取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续，高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时，风速迅速降低并产生特殊的湍流，使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用，因此，对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市，尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物（PM）浓度和40%的二氧化氮（NO2）浓度。因此，通过对植被的合理利用能过创造一个有效的城市污染过滤膜，对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题，相反它是一个长久的问题，从它如何形成，加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象，它只是地球环境污染的一个缩影。我们更应该探究它的根源问题，什么才是它形成的根源，什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题，但我们可以通过减少排放源，通过增加植被，加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼，越来越发达便利的交通，相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了，人们是否会怀念那晴朗的蓝天，向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

二：环境污染

就最近这几年来看，随着各地区的经济迅猛发展，环境污染问题也越来越严重，保护环境，维持生态平衡也成为了我们每个公民应尽的责任和义务，也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看，所谓环境，主要指我们所研究的主体周围的一切情况和条件。对于人来说，环境是指人生活于其中，并能影响人的一切外部条件的综合。人的生活离不开好的环境，在人类几百万年的历史进程中，环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等，都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质，创造出地球上高度的人类文明。但是，人类在开发利用环境资源的同时，也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物，例如说：大量的生活废弃品，塑料袋(也称白色垃圾)，一次性木筷，一次性饭盒，果皮纸屑。污染物对环境来说，毫无疑问，肯定有很大的危害，例如动物的腐烂的尸体会影响环境卫生，而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷，使用后随便一扔，影响了市容，破坏了环境。。

现在像我们柳疃镇、青乡乡，最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中，使水受到污染。又例如说，我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡，地区农民上海捕鱼，鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计，目前，全世界每年约有4200多亿立方米的污水排入江河湖海，污染了5.5万亿立方米的淡水，这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义，即水体因某种物质的介入，而导致其化学、物理、生物或者放射性等方面特征的改变，从而影响水的有效利用，危害人体健康或者破坏生态环境，造成水质恶化的现象称为水污染。水的污染有两类：一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近，我发现政府部门、昌邑环卫局开始大力整治环境，沿街排查污染源，青乡街也定点安置了便民垃圾桶，替代了原来垃圾围绕街道，臭气熏天的状况。各个村庄开始整治村内环境的污染源，使街道、村庄焕然一新!而这不是主要的，更重要的是我们每个人自觉保护环境，保护我们赖以生存的家园，为了我们更为了我们的后代，树立好榜样，奠基好基础，让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关，保护环境卫生从我做起，从现在做起：不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林，不践踏草坪;不污染水源。保护环境，我们有责!看你的行动喽!

小建议：家庭生活中的塑料瓶可以做成装饰品，可回收物品可以卖出，换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品，你也能开小店赚大钱了!化废物为贵宝，让自己的心情更舒畅，让自己的心灵更纯洁，让自己的家庭更温馨!

三：环境污染

在二十一世纪的今天，人类赖以生存的地球环境越来越恶劣，灾难频发，旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去，以我所受到的信息宣传，简单以为环境污染只是浓烟滚滚，或者水面上漂浮着垃圾、发出恶臭，蚊虫成堆、尘土飞扬等等。但是，今年从网络、报纸、广播、电视、人们的关注里，我似乎明白；现实的情况要糟得多。西南五省大旱，就是我们自己想都没有想到的原因，专家分析：因为在过去10几年中，西南从新西兰大量引进桉树速生林，为了求短期的经济利益，毫无限制的大面积种植，以用来工业造纸，从而导致物种生态环境失衡，形成地下水严重缺失。俗话说，十年树木，百年树人，可这种桉树两三年就成材，是一种巨大的抽水机和抽肥机，不断侵蚀着其他植物物种的生存空间，而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中，不断的在往恶性循环上发展，正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上，我看到温总理在一片干涸开裂的耕地上，捧着一颗枯死的禾苗，只说了一句话：“痛定思痛！”云南拥有大片的原始森林，风景名胜众多，地理环境独特，自古以来就是一个山清水秀，气候宜人的好地方，可是为了种植这种桉树，大量砍伐原始森林，想象这些经过几十年甚至数百年才形成的树木，仅仅是为了去满足最快速度的造纸而被破坏，真是让人可惜，并且痛心。据说旱灾的另一个原因，就是所有的大江小河都修起了水电站。对这一点我有自己的感受，早两年湘江的水面多么宽广，可是上游修了一个水电站后，下游的水明显减少，甚至连河床都经常露出来，同时影响到了城市自来水的引水工程，我都有这些感受，那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件，报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后，一些黑心商人把这些进行简单的提炼加工后，不但闻不出异味，加入香精后吃起来还挺香，但是对人体危害很大，我现在都不敢随便在外面吃东西了。环境污染的问题日益严重，影响到了我们生活的方方面面，对此我感到非常的忧虑。

四：河道为什么会污染

在我们学校旁边，有一条小河，听长辈们说，原来这里的河水清澈见底，河里鱼虾成群，夏天人们喜欢在水里游泳，还直接取水饮用呢！可如今，河水不但变得混浊，有时还有臭味呢！

为什么河水会发生翻天覆地的变化呢？经过我们全班同学的观察分析，河水污染有许多原因 。首先，人们不重视环保，乱倒垃圾。如有一次，我去张微家去玩，吃了一根香蕉，问她的妈妈：“阿姨，香蕉皮扔哪里？”只见她从我手中拿过香蕉皮，又随手用力一扔，扔进了小河，说：“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了，这时，如果你从旁边经过，一阵阵臭味就会扑鼻而来。我真是不明白，人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢？。其次，人们家里的化粪池的排污口就直接通向小河。特别是我们学校，大小便没有经过处理就流进了小河，让人看了真是恶心。河水不变臭才怪呢！还有人们给庄稼喷了农药后，就在河里洗药筒等等。由于各种原因使河水变得越来越脏，甚至发臭，更不用说饮用，就连小鱼也快要无家可归了。

我想向人们呼吁：“水是生命的源泉，没有水就没有生命，就没有我们这个美丽可爱的家园，所以请你们不要再伤害小河了，难道你们就没有看见小河在哭泣吗？”
