Industrial pollution is clearly one of the biggest contributors to our polluted landscapes, at least here in the west. There are plenty of causes of land pollution, from urban and industrial ones, to rural and agricultural sources.

But which kinds of land pollution are the most important? And what can we realistically do to help prevent more pollution?

This part of the site gives an overview of some of the most important causes of land pollution, including industrial pollution.

There are also some recommendations for helping avoid domestic land pollution incidents.

Click here for some good reading on industrial pollution and land pollution causes and solutions.

As we all know, Beijing is facing the air pollution, a kind of environment pollution. Now Beijing is also famous of hazy weather, which is harmful to people’s health because of PM2.5 and PM10.

Why is our capital suffering the hazy weatherIn my view, Beijing is a center of economy, culture and politics, so she has a heavy traffic. As a result, there are a lot of cars here, then the exhaust of them become a part of reason of the air pollution. Besides, in order to have a good economy development, there are many factories around Beijing, the exhaust of the factories become another part of reason of the air pollution. The most import, our country is a developing one, and do not have enough ability to solve the pollution well while focusing on developing, just like UK was called The City of Fog before.

Now, Beijing has taken a lot of actions to deal with the hazy weather. Firstly, setting up the Bicycle exclusive channel, people are

encouraged to ride but not to drive, in this way, the exhaust of cars is decline. Secondly, many factories are forced to move to Hebei Provence, thus, they can continue to make a contribution to Beijing’s economy development and the air pollution is controlled. Finally, the buses and subway have a lower price than other cities, so that people prefer to go on work by bus or subway. And the limit line caused by tail number is effect, too.

I persist that the air pollution of Beijing can be controlled someday later.

Last May 4th was my birthday.I had a party at my home.

My relatives and friends came to my home in the evening.And I got a lot of presents from them.My mother prepared a big birthday cake for me.

There are even candles on it.After singing the song “Happy birthday”，I shared the cake with my friend and relatives.Then we watched TV and listened to music.Same of the girls danced with the music.We had a good time that day.

Now I want to say “Thank you my friends.Thank you my parents！I ’m so happy！”

Which is better, shopping online or traditional shopping? Different people

have different attitudes towards it. Some people think that online shopping is

very convenient, for it can save them a lot of time and energy. It’s especially

helpful for those who are always busy with their work. Besides, through the

internet, they can get more information about the commodities they want to buy

and buy a lot of things that cannot be bought in local places.

Nevertheless, I’m not keen on online shopping at all, since most

commodities which are bought online are of poor quality. Once we are cheated, we

may find it difficult to make a complaint. Thus we should take more cautions

when shopping online.

In my eyes, I prefer traditional shopping, because I can choose what I

really need. Also, I can know the quality of every commodity more clearly. Even

if there’s something wrong with the commodities, I can still ask the sellers to

compensate for my loss.

I have a great time during the winter holiday, because I enjoy myself as

well as focus on my study. As it’s known to all, the Spring Festival is the most

important in winter holiday that would occupy much time to celebrate it.

Therefore, I finished my homework first, so that it won’t bother my enjoyment

during the festival. I finished my home work in one week. And I went shopping

with my parents. We bought a lot of things, especially snacks and fruits. Then,

it was the Spring Festival. We had a big dinner on the New Year’s Eve. My

parents prepared the big dinner and I could only act as assistant. The dinner

was so delicious that I ate so full. In the next several days, my parents and I

visited our relatives and friends or they visited us. Sometimes, we went out for

fun together. We children were always the most excited. Now, holiday is coming

to the end and I will go to school soon. I am so happy that I have a wonderful

winter holiday.

Some people in the fierce competition of the rough waves swept away, has never recovered. Some people are against the tuyere, set foot on top, on the shore, they succeeded. Because they have much a stick to it. Forefront for them is not a stumbling block, but padding their own foundation.

Born easy, live easy, life is not easy. Life is a process of life. No wind, no rain? It is because of the baptism of wind and rain to see the colorful rainbow; With the pain of failure will taste the joy of success. Turgenev in the rudin, said: "although our life short and small, but great everything is caused by the hand of the people; a life, realize the lofty mission, that is their supreme happiness in life." We are to create this society, inevitably some injury, through the tears.

Time, fast turn, across one dream magic song.

Life, be about to rush out a way to! In order to cause, in order to struggle in life, despite losing a lot of, but is there will be! And are often more important than lost, it is the value and meaning of life.

Life is long, the years.

How can we predict the future? But only clear conscience my heart! Life, because there is competition, people have power; Life, because of the struggle, the people to the pursuit of excellence.

Smoke in life, like a cloud, the wind. Transient. "Only the people and the backing car, there is no reverse time and road", since we came to today, and possession of todays social status and responsibility, only forward, forward, forward again! Dont retreat. Young people, more important is to see tomorrow, seize today, forge ahead in the quiet, perhaps before the sun mountain tomorrow, you created a miracle again!

Today is the National Day, but also our 30th anniversary of the founding of China. I am bored after a morning, in the afternoon, I went to my sisters house to play.

I am happy to the sister, but to her home I was disappointed, the original sister did not think what to play, we racked our brains, and finally thought of a game: grab the bench.

We found ten children to play, the rules of the game is this: Please the five children (including me and my sister) with the music around four bench circle. Music stop, we must immediately grab a bench to sit down. Who did not grab, who would be eliminated. The second round is four and three bench. The last round only two people and a bench, and who grabbed the last bench who would win. By aunt when the referee.

Big aunt first invited Wang Yue, Lai Yun, Yu Jing and my sister to play. The rest of the children on the side when the cheerleaders. I saw the two of them relatively standing, Yu Jing children did not show weakness, raised his head, Tingzhuo, not afraid of the way; look at Lai cloud students, half open eyes, hands into the trousers, are not See Yu Jing this skinny monkey. With the big aunt whistle, the game began.

When the music sounded, they turned around the bench. When they are spinning, we are seeing the gods. Music and suddenly stopped. Lai Yun seems to have no response over, standing on that look at my sister and grab the bench. But I do not know ye engage in, her eyes light up, found an empty bench. Lai Yun immediately ran to sit. Later, my sister was eliminated. The second round, three rounds of Lai and my two children were eliminated in turn.

The last round only two female students. As soon as the music sounded, they turned slowly around the bench. Their eyes staring at the only Zhang bench, and my heart is also very nervous. Our cheerleaders shouted: "Wang Yue Come on! Wang Yue will win! Wang Yue Come on!" Yu Jing did not hear the students to their own voice, it seems more tense. Tension is useless. Music stop, Wang first grabbed the bench more than half, Yu Jing grabbed only a small half.

Wangs victory, so that we are happy and jump again and again.

Through this game, our actions are more agile. I am so happy today

It is universally acknowledged that tour can make people feel happy; traveling is a good way to relax oneself. Tourist data shows that people in China made a great contribution to the world tourism, and it’s more and more popular for people to go out for vocation. Though reports criticized that tourism had brought harm to the environment, I still believe in the rising pace of tourism.

Well, there is no denying that at this moment, tourism has caused some problem to the environment, but what I want to emphasize is that such damage are raised by people, as long as we improve the environmental consciousness of our citizens, as well as perfect the public facilities, such as adding more dustbins to convenience tourists; building cafeterias to offer meals to them. I believe within a period of time, the situation can be relived.

Environment itself also has the ability to recover itself. Years ago, when there were no so many tourists, and no industrial pollution, trees grew well, flowers smelt good, sky was blue, water was clean. Why the nature seems so unnatural now? It must be our own problem, for we have took too much, but paid back too less. Think how we treat our land. It is really unfair.

Just as I mentioned before, tourism had brought great profit to our economic, whatever scenic spot it is, it must has the relationship with our land, our trees ,our water, etc., everything can’t separated from earth. So as you see, tourism won’t bring harm to the environment, but ourselves.

It is good for us to go out to feel different culture atmosphere, and to see different local conditions and customs, but remember, protect our nature resources.

写作题目

Individuals can do nothing to improve the environment; only governments and large companies can make a difference. To what extent do you agree or disagree?

范文

Nowadays, an increasing number of people are concerned about environmental protection and regard it as one of the most important challenges. However, whether only governments and big firms have resources and powers to preserve our environment is a controversial issue. My view is that every single citizen could also make a huge difference.

In the first place, it is clear that it is human activities that have the greatest impact throughout the history. Both environment contamination and conservation are the long-term process, and no single government or big company can meet this challenge alone. So whoever created the problem should be responsible for solving it; environment protection needs every one of us to continuously participate in.

Moreover, the publics wills and behaviors have critical influence on governments policies and companies strategies. For example, if everyone says no to plastic shopping bags and paper cups, the companies that manufacture such products will switch to environmental-friendly substitutes in order to survive in the market.

[关于改善环境质量英语作文

现在，咱们家乡的环境越来越差了，空气不再那么清新了，河水不再那么清澈了，我发现这是人们缺乏环保意识造成的。

有一天，我走在回家的路上，突然，一个香蕉皮从前面扔过来，我转身看了一下，是一位叔叔吃完香蕉后，随手把香蕉皮扔到了地上。我跑了过来，对那叔叔说：“叔叔，咱们不能乱扔香蕉皮，那会污染环境的。”叔叔不以为然地说：“不就扔了个香蕉皮。”我非常生气的说：“如果每个人一天扔掉一个香蕉皮，那地球不就成了垃圾站了吗？”叔叔的脸变的通红，把我手中的香蕉皮扔到了垃圾箱里，然后摸了摸我的头说：“哎，现在的小学生可真了不起，咱们大人还没有小学生有环保意识呢！我笑着说：“也许你还比咱们小学生还懂得环保。”我和叔叔都高兴的走了。”

通过这件小事让我明白了只要人人都保护环境，家乡的环境就会变得更加美好。所以，咱们应该保护环境，要知道，保护环境就是保护咱们自己呀！

随着地球资源的渐渐减少，呼吁环保的呼声日益增多。但是仍有大部分的人类肆意的破坏着生态平衡。有人高呼环保，背地里却干着见不的人的勾当；有的厂家对外宣称合理排行污水，却把江河当做污水排放厂······随着人类社会的高度发展，人类已进入了空前的文明时代，但我们面前的却是乌黑发臭的河水，成片的沙漠，光秃的土坡，作为90后的我们，应该把环保做的更好。

白色污染

伴随着人类生活文明的进步，白色污染日愈严重起来。塑料袋，塑料包装等虽是我们日常生活中必不可少的东西，它价格便宜，质轻，耐用，防水的几大特点被人们所看好。在中国的市场极大，我国也是世界上十大塑料制品生产和消费国之一。但处理这些东西比想象中难得多。一般塑料垃圾在自然界停留的时间可达200~500年。所以对于塑料类制品我们要抵制使用。

汞污染

汞是唯一在常温下呈液体的金属元素。俗称朱砂。汞可溶于水，空气中。它巨大的毒性令人谈之色变。它主要来源于电池等物品。据统计1970~1979年全世界直接向水体排放的汞总量达1.6万吨！排向大气的汞量也达10万吨。当水中或空气中的汞浓度过高时，会导致树木枯死，人类患上因汞摄入过高引发的病症，如日本南部九州湾有一个叫水俣的小镇，这里居住着4万居民，以渔业为生。1939年开始，日本氮肥公司的合成醋酸厂开始生产氯乙烯，工厂的生产废水一直排放入水误湾。该公司在生产氯乙烯和醋酸乙烯时，使用了含汞的催化剂，使废水中含有大量的汞。这种汞在水体中，被水中的鱼食用，在鱼体内转化成有毒的甲基汞。人食用鱼后，汞在人体内聚集从而产生一种怪病：患者开始时，只是口齿不清，步履蹒跚，继而面部痴呆，全身麻木，耳聋眼瞎，最后变成神经失常，直至躬身狂叫而死。1972年据环境厅统计，水误镇共患水误病180人，死亡50多人，就在新线县阿赫野川亦发现100多水误病患者，8人死亡。据报到，患者人数远不止此，仅水误镇的受害居民，即达万余人。

环保事业说大很大，说小很小。往大的说，可以造成成片的水域污染。往小了说，只要我们每人从身边的小事做起，人人环保低碳，环保事业也可以是一件很小的事。如果我们少用些塑料袋，少乱丢些垃圾，那么这个世界上便会少些随风飘舞的白，多些生机勃勃的绿；也会少些乌黑肮脏的河，多些碧蓝清澈的湖······

如果我们每个人在地上看见一个塑料袋不是直接走过，而是弯腰拾起；如果我们每人不是随意乱丢垃圾，而是做到合理分类垃圾；如果我们每人都少用些塑料袋，多用些环保袋。那么我相信地球母亲会少些愤恨的泪水。。。。。。

保护环境，从我们身边做起！

Seeing mywhole education history, I have many teachers. But my favorite teacher is onlyone. He is Mr Lu. He is my middle Chinese teacher and head teacher. He is aboutfifty years old. Maybe he works too hard, so his back is a little bent.

He alwayswears a black glasses. He looks amiable but serious in study.

He always thinks us before everything. His class isvery interesting and full of different kinds of encouraging stories. He is verystrict to us in study. But whoever has difficulties, he would help us withouthesitation.

Sometimes he plays the role of a strict teacher, sometimes he takesthe place of a kind father.

纵观我整个受教育史，我有过很多老师。但我最喜欢的老师只有一个。他是陆老师。

他是我的初中语文老师兼班主任。他大约五十岁。也许是因为工作辛苦，所以他的背有点弯了。

他总是戴一副黑色的眼镜。他看上去很和蔼可亲，对学习却是很严格的。他总是把我们放在第一位。

他的课是非常有趣的，也经常讲各种不同励志故事。他对我们学习很严格。但无论谁有困难，他都会毫不犹豫地帮助我们。有时他是一个严格的老师，有时候他是一个慈祥的父亲。

地球环境变了，那原来洁白的小溪变成了垃圾桶，绿色的草地变成了沙漠。

让我们开始对一些人们苦苦祈求，让他们不再破坏环境了，小草的祈求是：“请你们爱护我们，不要把你们那无轻重的脚，放入我们美好的家园,也不要乱扔果皮，让一些虫子来咬我，请你们帮帮小草，在小草旁边写上一句话“爱护小草人人有责”。”

小溪的请求是不要在把我当那又丑又脏的垃圾桶，我也要一件漂亮的衣服，请你们行动起来，在我的旁边立一个牌子写上：“小溪是大地的脸，你破坏了小溪就等于破坏了大地。”

地球妈妈的请求：“请不要我美丽的脸型，我应该得到的是一张圆圆的、漂亮的、五彩的形状，不应该像一个苹果被虫子咬的稀巴烂。请你们帮助我向全国各地播放一条新闻，小溪小草都是旅游景点的美好东西，请不要破坏它。

宇宙的祈求：“你们以后不要在发射什么火箭了，你们火箭的一些飞船零件都在太空直接打到我们身上，让我们痛的要命。”

请求你们让这些宇宙垃圾回收回去，免得让我们接受这样的痛苦了，让这些宇宙垃圾被你们回收回去，让我们过上好日子，请你们在宇宙建立一个宇宙垃圾回收站，把打到我们身上的垃圾回收，为我们造福。

1、审题：审题是做到切题的第一步。所谓审题就是要看清题意，确定文章的中心思想、主题，并围绕中心思想组织材料。

2、进行构思，列出简单的提纲，打造文章之骨架：审好题、立好意后，就要写提纲，打造文章的骨架。文章布局要做好几件事：安排好层次段落，铺设好过渡，处理好开头和结尾。

3、扩展成文：根据字数多少扩展成篇。扩展的内容一定要紧扣主题，千万不要写那些与主题不相关的内容。展开的方式包括：顺序法、举例法、比较法、对比法、说明法、因果法、推导法、归纳法和下定义等。可以根据需要任选一种或几种方式。

在这一步骤中还需注意三方面问题：

1、确保提纲中段落结构的思路与各段主题句的一致性。只有这样，才能保证所写段落不偏题、不跑题。

2、要综合考虑各个段落的内容安排，避免段落内容的交叉。

3、用好连接词，注意段落间、句子间的连贯性。要做到所写文章层次分明，思路清晰，文字连贯，就需要在句与句之间、段与段之间架起一座座桥梁，而连接词起的正是桥梁作用。

在扩展的过程中也有些窍门，以下几点可供参考：

1、在整篇文章中，避免只是用一两个句式或重复用同一词语。英语中存在着极为丰富的同义词，准确地使用同义词可以给读者清新的感觉。同时要灵活运用各种句式，如倒装句、强调句、省略句、主从复合句、对比句、分词短语、介词短语等，从而增加文章的可读性。

2、使用不同长度的句子。如果一个意思用一句话写不清楚的话，通过分句和合句或用两句、三句来表达，增强句子的连贯性和表现力。

3、改变句子的开头方式，不要总是以主、谓、宾、状的次序。可以把状语至于句首，或用分词等。

4、学会使用过渡词。递进furthermore，moreover，besides，in addition，then，etc ;转折however，but，nevertheless，afterwards，etc ;总结finally，at last，in brief，to conclude，etc ;强调really，indeed，certainly，surely，above a11，etc ;对比in the same way，just as，on the other hand，etc。

5、确定文章用第几人称写，基本时态是什么。使用人称时人物不能张冠李戴或指代不明。时态要尽量保持一致。

检查修改：要检查复核，不要写完了事。

要留时间通读全文，修改可能出现的错误。检查上下文是否连贯，句子衔接是否自然流畅。检验的标准主要是句子是否通畅，该用连词的地方用了没有，所用的连词是否合适，是否有语法错误，主谓是否一致，动词的时态、语态、语气的使用是否正确，词组的搭配是否合乎习惯，是否有大小写、拼写、标点错误等，还有就是注意卷面整洁。

可归纳为：中心突出，主题明确;层次清楚，条理清晰;表达

Life is a long process, we have too many expectations, will inevitably encounter disappointments and frustrations. The ideal on the shelf, come back to find that we like a fish, always thought that I had wings are birds, but finally I know that I cant fly. Life like water, and sometimes cloudy, sometimes clear, we struggle against social this big VAT - "I often feel life owed me, why do people always happiness and joy than yourself?" In the face of setbacks, we complain about life deceives us, we thought there was no hope of their life. We often compared himself to lost the swan, but forget oneself want how to fly.

As a child, then established the goofys desire. So many years, has been trying to, in insist, waiting for, has vowed to make yourself proud fly. But the difficulty and the setback already ambush all around, lets get stuck here. We have very strong telling myself, dont because at present small setbacks, but let themselves to give up the dream life? Even if life has deceived me, but this is not fearful; The enemy attack me, also is not terrible, terrible is betrayed our dream and gave up. Even live tired, live hard, also want to insist on your dream, give their best confidence and courage, toward a glorious and brilliant tomorrow. But few people do it?

But grew up, social this big cylinder multifarious colors, we see more dazzling. But we think the bottom of my heart has its own principle, can easily be tempted by the outside world? When looking back to the historys dust, always feel oneself still maintain magnanimous feelings from the past, still with his own emotion, but always failed for himself and guilty about ideal life. We should think like this: one failure is nothing, still remains the most quality of the things we do, we insist the dream is still the most valuable. With the accumulation of time, looking at others get summer fruit, they themselves are empty。

On Water Shortage

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected peoples daily life and hindered the development of the global economy.

A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. Whats worse, pollution and waste of fresh water aggravate the situation.In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable

for us to expect a brighter future.

What is art? When people think about this question, they will naturally

think about all kinds of musical instruments or the great paintings in the art

museums. Art seems to so far away from the ordinary people, but I don’t think

so. Art is everywhere. For example, the delicious food that is made by our

parents is the great art, and the value of the food is to bring people the great

joy when they have a taste of it. The scenery around us is the visible art, when

we appreciate it, our mood become eased. Art is something that brings people the

positive value for me, so art is around everybody. If we take time to slow down

our pace, then we can enjoy art from life and feel the comfortable

lifestyle.

在我们的家乡,由于经济较为发达,几乎每家每户都拥有车子。汽车已经成为人们不可缺少的交通运输工具。它给我们们的生活和工作带来了极大的便利。但是，由于汽车数量的不断增多，汽车排放出来的尾气，也给地球妈妈带来了极大的危害。趁着周末，我们决定对“汽车尾气的危害”做一个调查。

通过上网查找资料，我们了解到汽车排出的废气中含有1000多种气体成分，其中对人体健康和环境危害最大的有一氧化碳、碳氢化合物、氮氧化物、二氧化碳等。一氧化碳是汽车排放废气中浓度最大的污染物，是无色、无味、无臭的窒息性气体。吸入过多一氧化碳会使人体缺氧，使中枢受损，引起功能性障碍，直至死亡。氮氧化物是各种含氮化合物的总称，汽车尾气中以一氧化氮居多，并有少量二氧化氮。氮氧化物的毒性很高，有强烈的刺激作用，会导致胸闷、咳嗽、气喘、肺炎乃至肺水肿。二氧化碳是大气主要的温室气体之一。排放过多，会使全球的气温升高，引起气候的不断恶化。

为了证实这一危害，我们把要做实验的意图跟家长说了，并征得了他们的支持。我们叫周旻晖爸爸发起车子，不要前进，原地不动。又拿出一盆开得正旺的菊花放在小板凳上，将小板凳拿到了汽车排气管后。一股股臭熏熏的黑烟从花瓣间飘过，一两分钟过去了，花儿还和原先的差不多；五分钟过去了，有几片花瓣已经凋谢了，十分钟后，那原先湿润的土壤都变得非常干燥，没有水分了。二十分钟后，那原先饱满、充满活力的茎都变得紧绷绷的，好像一根电线。通过这个试验我们明白了汽车尾气对植物的危害确实是很大的。

但是，为了进一步证明汽车尾气对动物有没有危害，我们又做了个实验。我们去王哲奶奶家的鸡窝里抓来了一只小鸡。那只小鸡一直望着我们，我们心想：为了证明汽车尾气排放对人类有哪些危害，已经牺牲了一盆花了。现在要拿这只可怜的小鸡做实验，真是有点于心不忍呢。但是为了寻找问题的答案，我们咬咬牙，还是决定坚持做下去。和上次差不多，我们先把小鸡用一个笼子关着，摆放在排气管后面，然后又叫叔叔将汽车发动。一股股黑烟又从排气管里冒出来了，一会儿功夫，小鸡的绒毛就被熏成灰色了。10分钟后，我们看到小鸡被熏得奄奄一息了。为了保住小鸡的性命，我们赶紧将它拿开，放在地上。看到小鸡跌跌撞撞的，我们心里一阵阵酸痛。我们对叔叔说，原来汽车的尾气对植物和动物的危害真的是这么大的呀。周旻晖爸爸语重心长的说：“任何事物都有两面性的。汽车作为人类进步的产物，它给人们带来了许多的便利，但同时也给人们带来了很多的危害啊。现在我们们国家也是很注重环境保护的，有很多城市都已经在开展‘无车日’活动了。”

是呀，为了我们这个赖以生存的地球，我们要争做环保小卫士，积极宣传汽车尾气对人类的危害，请爸爸妈妈们少开车，能步行的尽量步行，不仅环保，而且还可以锻炼身体，这样是不是一举两得呢？
