环保类高中英语作文（汇集20篇）

There is an old Chinese saying: Top students come from strict teachers.

Perhaps affected by this saying for a long time, we believe it right. However,

as time flies, lots of things have changed. Therefore, I am eager to discuss

what relation is the best between teachers and students.A teacher can treat a

student in two ways .One is strict, and the other is friendly. Most teachers

prefer the first way.To start with, we certainly have to admit that strictness

is very effective, especially to the naughty pupils.

As pupils we aren’t able to control ourselves well or fix our attention on

one thing for a long time. We do most things because they are interesting or we

feel like doing. We are always looking out of the window in class. Sometimes, we

get to play games and forget our homework. On this occasion, strictness is a

must. It not only forces us to do the right thing, but also helps us develop a

good learning habit, which is of great importance during our whole life .In

other words, it is the first step to success.Still, everything has two sides.

Its weak points are very obvious. You see, there’re top students in a class,

where average students make up the majority. Then teachers’ orders or

suggestions are for the majority, not for top students. However, top students

always have their own study plans and prefer special homework, so orders usually

won’t take great effect on them.

Maybe you have thought out that teachers can give orders only to the

majority and set some freedom to top students. However, it’s impossible .For a

whole class, teachers couldn’t give order to part of the class, for the majority

would question why they needn’t do such work, but we need? It would be probable

that they think teachers treat them not equally, and will not obey teachers’

orders any more. This is a difficulty for teachers.It also has another

disadvantage——the communication problem .Since teachers are strict, we never

tell teachers our personal affairs or secrets. Mostly we just tell them to our

friends, but as students too, they couldn’t help to solve our problem, such as

puppy love, communication problems or study problems .Not being solved

completely, they always disturb us, influencing our daily life and study. I’m

sure that you think that making friends with teachers can solve the problem, and

you are eager to do so as well. But if we do so, new problems will come out .You

see, an adult couldnt control himself well at times, let alone us students.

However if teachers are our friends, I doubt whether their orders will take

effect any more .You see, have we ever treated our friends’ orders as orders? We

think they’re only jokes. This is another difficulty for teachers.Additionally,

our parents have the same problem. Yes, we need to be friends, but not complete

friends. We need to keep a certain distance, making us communicate well and

willing to take your orders. I remember a story.One day, a lady had her rest

room decorated. And a skilled worker was bricking up the wall. Seeing large

cracks between the bricks, she questioned why. The worker told her after this

summer, the bricks would become bigger, and those cracks would disappear.That is

not only decoration, but also communication. The principle is the same.

健康对于我们每个人来说是非常重要的，但你的父母天天忙于工作而忽略了这个问题，你很为他们担忧。请你以此为话题，并结合提示给他们写一封信。

4.不要工作太晚，要早休息。

要求：1.短文结构完整，意思连贯，语言流畅，语法准确，符合逻辑;

Dear Dad(Mum),

You’re so busy every day that you don’t pay much attention to your health. I’m worried about your health all the time. I’d like to give you some suggestions. I hear walking is the best sport. Your company isn’t far from home, is it? Why not walk to the office? You’d better take exercise at least once a week, such as playing tennis in the gym. Going to swim is also a nice choice, too. What’s more, it’s necessary to have healthy food. Try not to stay up too late. Having enough sleep can help your brain work better.

Dad, please accept my advice. I really wish you healthy!

Your loving son (daughter)

Tom (Mary)

亲爱的爸爸(妈妈)，

你每天这么忙，你不重视你的健康。我对你的健康担心所有的时间。我想给你一些建议。我听到走路是最好的运动。您的公司没有远离家乡，是吗?为什么不步行到办公室吗?你最好锻炼，每周至少一次，如在健身房打网球。去游泳也是一个不错的选择了。更重要的是，它需要有健康的食物。尽量不要熬夜太晚。有足够的睡眠可以让你的大脑工作得更好。

爸爸，请接受我的意见。我真的希望你健康!

您的爱子(女)

汤姆(玛丽)

[给父母的一封信高中英语满分作文

一、勤读、多背词汇，好精句

要想写好一篇文章，没有充足的词汇量是不行的。课文中的俗语和谚语的识记是通过背诵来完成。背诵是语言学习的重要手段，也是语言学习的必经之路。

1.背词句，背诵课文中的重点句型和短语尤其是课文中的俗语、谚语和经典句子。

2.背范文，将近几年高考中的作文和课文中好的段落以及报刊上的各种各样的体裁和优秀文章让学生多背，这样学生才能在自己的脑子中形成一定的写作框架，做到心中有数。

3.多读书，用英语进行思维。为了培养学生用英语思维的定势，增加对英语国家文化、社会风俗、风土人情、思维方式的了解，扩大视野，选择课外阅读，提高学生分析、判断、猜测、推理和领悟的能力。部分学生在写作时习惯用汉语思维，然后再逐句译成英语，结果写出来的文章是汉语式的英语。要想学会用英语进行思维，就要有计划、有目的地培养学生的语感。一个重要的方法就是大量阅读，选择精彩的词句、文章和佳句，引导学生阅读，摘抄或背诵来培养语感。

二、亲自动手，自己写作

教师应注重基本功训练，严格要求学生正确，工整，熟练地书写字母，单词和句子，同时注意大小写和标点符号。进行组词造句，组句成段练习时，要学生写出最简单的短句，为以后英语作文打好扎实的基础。这种练习可以安排在刚开始的训练中，要求学生能够用最基本的时态去完成写作。另外结合高中英语基础知识的复习，对学生提出较高写作能力的要求。

1.范例引路

学生在进行短文写作训练时，教师应提供各种文体的范文，讲明各种文体的写作要求和注意事项，如日记，便条，书信，通知的格式等，并给予必要的提示，并掌握各种体裁文章的格式。在平时的教学中，教师应该指导学生应对高考中各种体裁文章。

2.限时训练

教师当场发题，限时交卷。这样能促使学生瞬间接受信息，快速理解信息，迅速表达信息，提高实际应用和应试能力。这一步是关键，也是学生的的难关。必须要求学生在写作过程中牢牢记住以下口诀：“先读提示，要点与格式要弄清;时态语态要当心，前后呼应要一致;结构搭配，莫违背;文章写好细检查，点滴小错别忽视”。学生明确目的，并掌握要领后，要严格在规定时间内完成作业。

3.多想精炼

在平时的教学中，教师要求学生多看、多听、多想，用心体验和感悟身边的人和事，然后将自己的体验和感受用英语写出来。教师可要求学生每周写两篇，有话则长，无话可短。对不同水平的学生作不同的要求。鼓励表达自己的看法和体会。

此外，有时根据所学单元知识布置一篇作文，或给学生提供一些与时事或与学生学习活动和生活有关的材料。此类话题的现实性能诱发学生的写作兴趣，使其有话可写，有感而发;还能增强其信心，使其写作能力、技巧得到充分的锻炼和提高。对于有待进步的学生要及时励，激发其写作热情，增强其自信心。

4.自改互改

对照范文，学生先对已查出的表达有误的地方进行初改。范文不可能把各种表达方式都包括进去，况且学生作业中的错误也不尽相同，因此，还可安排学生互改。以同桌两人为宜，这样同时进行了改错训练。

三、培养学生良好的写作习惯

写作教学是一项“由简单到复杂，循环往复不断上升的”过程。不是一蹴而就的，需要教师在教学中由浅入深、由简入繁、由易到难、循序渐进。起始阶段，培养学生良好的写作习惯是非常重要的。要求学生做到以下几点：

1.认真审题。要求学生认真审读图表或提纲，领会意图，捕捉信息，确定文章时态及体裁。

2.写提纲。教师引导学生构思文章要点，写出每个段落主题句、关键词，然后确定细节和内容要点。

3.写初稿。经过审题和列提纲后，学生开始写作，教师指导学有意识地使用固定句型，使用关联词，把段落按逻辑顺序连成一体，形成基本连贯的初稿。

4.检查错误。检查是书面表达不可缺少的环节，学生完成初稿后，老师指导学生从以下六个方面进行修改和查错：(1)看要点是否齐全，有无遗漏;(2)体裁是否恰当，有无偏题;(3)内容是否连贯，有无缺词;(4)语法是否正确，人称、时态、语态、冠词及名词单复数等有无错误;(5)用词是否得当，有无习语及固定搭配等方面的错误(6)最后注意句与句、段与段之间有无合适的连接及过渡，经过有效的训练，学生犯的错误会逐渐减少，同时学生的书面表达能力会逐步提高。

总之，教学有法，教无定法。教师面对的教育对象是多样化的，因此在教学中一定要关注学生的个体差异，采取相应的措施，激发学生写作的兴趣。让学生参与实践，体验成功的快乐，循序引导，学生点滴积累，不断磨练，这样能达到理想的效果。

In my childhood, summer holidays left a deep impression on me. They brought me many happy memories now.

Everyday we got up early then. Though there was not much modern entertainment, we could still be content with climbing trees, swimming in the small river, catching butterflies , bees and or something. Anyway, we could give a full play to our imagination and intelligence to enjoy ourselves.

The most enjoyable time in a day was night. All people would go out to be cool. They talked with each other freely and happily. Sometimes we would gather around an old grandfather and listen to an old story, which would always attract a lot of children. Our grief and joy all came from story. Sometimes we would carry out a small stool, made it as a horse, and then we would ride on it in a circle. We acted as knights. The front part of the stool was moved up and down to knock at the earth and sent out the sound of “du du…”. It was often followed with our folk songs. But parents could not accept this game because it was too noisy, and they couldn’t bear it. We were always forced to dismiss. But soon we could find a new program.

About the midnight, people would go back to sleep one after another. Under the pressure of parents, we had to go home, too. But as soon as we got to bed, the plan of entertainment next day appeared in mind. Then we could sleep with a smile.

Should students make friends on line? Some people say yes. The Internet

helps make many friends. Chatting on line, students can express their feelings

and opinions more freely, and even get help with their foreign language

studies.

Others, however, think students should not. They say making friends on line

is a waste of time, which should be spent more meaningfully on study. Besides,

some students, get cheated on line.

It is my opinion that students should place their study, health and safety

before other, things. As for friendship, we can readily find it in our

classmates and other people around us.

To be successful, students learn many knowledge so as to master as more skills as possible. Some believe that the key to realize our dreams is to work hard and others treat chance in the first place. While today is the information world, the one who masters the all-sided source will have more chances to be successful. In my opinion, the most important skill is the social skill, because we need to make connection with others, we are not doing business with ourselves, so it is in need of having relationship with others. The good social skill can help us attract attention easily and impress the future partner. If we are bad in communicating, how can we let others know our advantages and trust us. So promoting ourselves is the first job, from now on, don’t be shy.

Ideal is good, is happy, is the ideal starting point for success. I think, every student has a beautiful ideal, to ask what is my ideal, I would say: "my ideal is that when a CCTV news".To ask why I have this ideal, or from the start of life. "CCTV news broadcast" is our Chinese important news, not only we the people of the whole country, there are many foreigners will see, so the occupation represents the image and language level in china. There is a reason: this work can make our country peoples access to the latest news, let us Chinese political connections. In this work the way repay our great motherland mother.The ideal is behind the efforts of one hundred thousand and difficult challenge. In the future days, I will try my best to learn culture while learning about presided over knowledge, and from the aspects of improving, show ego, challenge higher field. If you want to succeed, must fix its body, like a candle, you want to burn it up, there must be a match, the match is our efforts.The ideal is a life, in our heart sowed the young; the ideal is a whip, let us work hard; my ideal is that when a CCTV news, it is my life goal.

理想是好的,是快乐的,是成功的起点。我认为,每个学生都有一个美好的理想,问我的理想是什么,我会说:“我的理想是当一个央视新闻工作者”。问我为什么有这样的理想,因为这来源于生活。“央视新闻联播”是我们中国重要的新闻,不仅我们整个国家的人民,有许多外国人会看到,所以职业代表着中国形象和语言水平。还有一个原因:这个工作可以使我们的国家人民访问到最新的新闻及了解我们中国的政治关系。以这样工作的方式来偿还我们伟大的祖国母亲。理想的背后是十万年的努力和困难的挑战。在未来的日子里,我将尽我最大的努力学习文化,学习知识,学习改善这些方面,展示自我,挑战更高的领域,如果你想要成功,必须修复它的身体,像一根蜡烛,你想烧掉它,必须有一场比赛,对手是我们的努力。理想是生命,在我们心中播下了年轻;理想是鞭子,让我们努力工作,我的理想是当一个央视新闻工作者,这是我的人生目标。

Environmental problems are becoming more and more serious all over the world.

For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.

The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.

全世界的环境问题变得越来越严重。

例如汽车污染的空气影响了人们的呼吸，工厂释放污染的气体，山上的树木被砍伐，污水不断被排人河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。事实上，污染正威胁我们的生存。

地球是我们的家园，我们有责任为我们自己和我们的后代去照顾好它。庆幸的是，愈来愈多的人们已经意识到这些问题。政府已经采取了很多措施去解决这些问题，法律已被通过以制止污染。我希望这些问题在不远的将来能得到解决，我们的家园变得越来越好。

On Sunday morning, my parents took me to the zoo. We dint go there for a long time.

Last week, my classmates told me that the zoo added some funny entertainment facilities. I was very curious. So, I asked my parents to took me there and they promised to. We got there at 9 oclock. There were many people. Most of them were parents and children.

We first went to see the animal. I like parrots most. And then we saw the animal shows. Elephants, tigers, lions and monkeys did wonderful shows for us. People were happy, especially the children.

After that, we went to experienced the entertainment facilities. My mum was too scared to be with us. So, only my dad and I played. It was so exciting, but I was a little dizzy. However, I was very happy.

It was a great day.

星期天早上，我父母带我去动物园。我们很久没去那里了。

上周，我同学告诉我动物园新增了一些好玩的娱乐设施。我很好奇，所以我叫我妈妈带我去，而且她答应了。我们9点就到那了。那人很多，大部分是家长和孩子。

我们首先去观看动物。我最喜欢鹦鹉。接着我们看了动物表演。大象，老虎，狮子和猴子给我们表演了精彩的节目。人们都很高兴，特别是小孩子。

之后，我们去体验了娱乐设施。我妈妈很怕，不敢跟我们一起。所以，只有我和爸爸玩。它很刺激，但是我有一点点头晕。但是，我还是很开心。

这真是很棒的一天。

I think my plan is the best possible one .I’m hopeful the winter holiday will come soon .

High school is very important in one’s lifetime. Nowadays, the movies about the high school time are so popular, but the stories are exaggerated, my memories about high school life are so different from the movie. During the three years, study occupied most of my time. I fought for the future with my classmates. We studied together and shared our opinion about the difficult points. When I made great progress, I was so happy, but when I fell behind, I would not give up. I grew up and became patient, I was not the little girl anymore. In the part-time, I would go to play basketball with my friends, it became the most exciting thing at that time. Though the high school life was simple, I gained a lot. I would never forget the classmates who worked with me together.

高中是一个人一生中非常重要时刻。如今,关于高中生活的电影如此受欢迎,但这些故事被夸大了,我对高中生活的记忆是不同于电影里面的。在三年里,学习占据了我大部分的时间。我和我的同学们一起为未来奋斗。我们一起学习，并且分享我们对难点的意见。当我取得很大的进步的时候,我很高兴,但是当我落后,我也不会放弃。我长大了,变得有耐心,我不再是个小女孩了。在课余时间,我会和我的朋友一起去打篮球,这成为最令人兴奋的事情。尽管高中生活很简单,但是我收获了很多。我永远不会忘记曾我和一起学习的同学。

Since birth, human, all the food and clothing to the line and the production, life, all depends on the planet we live in, the earths atmosphere, forests, oceans, rivers, soil, grassland, wild animals and plants, etc., has formed a complex and closely related to the natural ecosystem, which is fundamental to the survival of the human environment, for a long time, the process of human civilization has been stranded on the conquest of nature plundering, the protection of nurturing the human earth never seem to think of and return, in brilliant civilization achievements at the same time, human plunder of nature is an admission that devastated the planet we live in and the growth of population and the increase in production activity, and the impact to the environment, pressure on the environment.

It is well known that human is the natural environment for survival, continuation of the material basis. However, with the development of modern industry, the destruction of the natural environment has suffered more and more serious. Air pollution, water pollution, land pollution... That cant find a piece of pure land in the world.

You may want to, want to important is the development of science and technology, science and technology developed in the environmental protection is not late, after that you can want to regret then. If we now enjoy too much against the victory of nature, think what we have made remarkable achievement, that we are not far from the destruction is

Climate warming, the hole in the ozone layer, acid rain and toxic waste, extinction in the wild, as well as the air and water pollution and so on, this is our current faces a series of global environmental problems, in the face of these problems, what should we do?

Everybody is responsible for protecting the environment, we should start from the environment around, from start to protect the surrounding environment, for example: abide by the provisions of the relevant banned throw all kinds of waste, the waste thrown to the designated place or containers, avoid using disposable beverage cups, lunch boxes, plastic bags, cardboard boxes, etc. Instead, it can greatly reduce waste, reduce waste disposal work pressure, take good care of trees and flowers, little New Year card, keep clean, etc. Is small, but, as long as we begin, working together, start from saving resources and reducing pollution, adjust their own way of life, we can protect the earth to make a contribution.

Do save resources, protect the environment, protect the master of the earth.

人类自诞生起，一切衣食往行及生产，生活，无不依赖于我们所生存的这个星球，地球上的大气、森林，海洋、河流、土壤、草原、野生动植物等，组成了错综复杂而关系密切的自然生态系统，这就是人类赖以生存的基本环境，长期以来，人类把文明的进程一直滞留在对自然的征服掠夺上，似乎从未想到对哺育人类的地球给予保护和回报，在取得辉煌的文明成果的同时，人类对自然的掠夺却使得我们所生存的这个星球满目疮疤，人口的增长和生产活动的增多，也对环境造成冲击，给环境带来压力。

众所周知，人类是以自然环境为生存，延续的物质基础。但是，随着现代工业的发展，自然环境却遭受到愈来愈严重的破坏。大气污染，水污染，陆地污染……以至世界上再也找不到一块净土。

或许你会想，想在重要的是发展科技，科技发达了之后在去环保也不迟，那你到时候可要后悔了。如果我们现在过分陶醉于对抗大自然的胜利，认为我们取得了什么了不起的成就，那我们离灭亡也就不远了

气候变暖，臭氧层空洞，酸雨，有毒废弃物，野生生物灭绝，以及大气、水污染等，这是我们当前面临的一连串全球环境问题，面对这些问题，我们该做些什么呢?

保护环境，人人有责，我们应该从身边的环境做起，从保护周边的环境做起，例如：遵守有关禁止乱扔各种废弃物的规定，把废弃物扔到指定的地点或容器中，避免使用一次性的饮料杯、饭盒、塑料袋，用纸盒等代替，这样可以大大减少垃圾，减轻垃圾处理工作的压力，爱护花草树木，少赠送贺年卡，保持清洁等。虽是小事，但是，只要大家动手，一起努力，从节约资源和减少污染着手，调整一下自己的生活方式，我们就能为保护地球做出一份贡献。

节约资源，保护环境,做保护地球的小主人。

During these two years, we have seen many movies about the youth, the

directors try to remind people of their passed early days. Indeed, when people

thinking about their days in the school. As for me, when I see the movie, I will

think about my high school days, it was so unforgettable for me, my friends and

I studied so hard together, our strong friendship was built at that time, the

stupid things we did always makes me laugh. Everyone will have an unforgettable

memory in their early life, the memory fulfills their life.

Life is each person s wealth, because the world with life and colorful, full of vigour, let us love and cherish own life, seize every minute of life. Life is short, be gone for ever, human life is fleeting, time can not be reversed, we can only in a limited life infinite brilliance.

A Lovely Cat

Several days ago, Mother brought home a little cat. I gave her a nice name "Mimi".

She is black all over except her: four feet and a small nose. There is also a white bib on her chest. Can you imagine what she looks like? Every morning she gets up the earliest. Then she always climbs up my bed and wakes me up. When we sit at table having our meal, she often runs under the table and even climbs onto our knees, it seems as if she was saying, "Let me join you. I want something to eat."

"Mimi" likes to lie onthe floor in the sunshine. She feels;comfortable that way. She looks more lovely when doing that.

I like "Mimi" very much because the cat brings us a joy of the family. 可爱的小猫

How to improve network security

As time goes ongoing surfing on the Internet become more and more popular.It is a new phenomenon and sounds an alarm (for online security ).

Network security cover anti- virus network security and hacker protection . Together with the technology of Access Control redundant backup recovery and network security it makes an allround security system . Many companies devote to the information security technology and product research and development production and sales providing advanced network security solutions . Firewall just is an effective measure of network security .如何提高网络安全

随着时间的推移，上网冲浪变得越来越流行，这是一个新的现象，听起来是一个警钟(在线安全)。

网络安全覆盖防病毒、网络安全和黑客保护。结合访问控制技术、冗余备份恢复、网络安全，它使一个全面的安全系统。许多公司致力于信息安全技术和产品的研发、生产和销售，提供先进的网络安全解决方案。防火墙只是是网络安全的一种有效措施。

绿，一种生命固有的本色。森林是绿的，草地是绿的，大地也是绿的。世界万物多散发出“绿”的光芒，我们人类的生活离不开绿色，低碳的生活也由此开始。

自从世博会以来，绿色的出门，低碳的生活成为了一个热门的话题，城市到处可见宣传着关于低碳生活的方方面面;再加上广州亚运会的成功举办，它让全亚洲，全世界看到了一个天更蓝，水更清的城市。让这座城市的人们感觉到低碳环保的生活方式带来的好处。

我们家也慢慢的加入到了这个行列，积极响应号召，去向着低碳的生活方式靠拢。俗话说，勿以善小而不为之，勿以恶小而为之;我们尽自己所能，在生活的点点滴滴注意减耗。以前洗澡时间要花上半小时之多，那个水龙头不关的那个水半小时就哗哗的溜走了，丝毫没想到过节约。在酷热的夏天，空调总是不停的运转，温度也总是很低的，估计每天排放的二氧化碳多是个巨大的数字。但是现在我们常用洗脸或洗澡剩余水集齐来冲刷马桶;用淘米的水浇园子里的花花草草;空调的温度也不会一直是最低或最高，调到合适的人体适合温度;还会利用家里的一些废弃物品改造，如一些肥皂盒，礼品盒等少加剪裁就可以轻松的做成一个漂亮的储物盒，可以在里面放些针线，小剪刀等生活物品……

以前，出门是一个决定用私家车的代名词。可是现在，家中除了需要集中去超市够买生活用品外，尽量使用公共汽车，地铁，或者在小区门口可以租用自行车，大大的降低了二氧化碳的排放量。去年，我国开始大面积推个使用环保袋，逐步淘汰终结使用塑料袋;现在的生活出门携带一个环保袋是一个必不可少的细节了。相信终有一天白色的污染将是过去时的代名词，迎来的是一个美好绿色的新世界。

绿色低碳生活需要的是一种态度，是一点一滴从小事做起的毅力。如果每个家庭多这样做出这样的实际行动，我们的生活将变的多么的美好，我们的天空会变得更蓝，夜晚的星星会变的更亮。减少碳排放是我们的一直责任，而它也一定将是我们新的生活方式。

我们只拥有一个地球，我们依赖这它，共同的命运将我们紧紧联系在一起。只有从现在做起，才能让地球不在哭泣，让那些伤痕愈合，变成一种温馨，让我们不断的进步，做的更好!

今天，你低碳了吗?明天呢……

This summer vacation, I joined a social practice to be a part-time tourguide. There I found something that impressed me a lot.

People who love traveling are always finding places to take a vacation, which caused a lot of troubles.For example, I found that some people were used to dropping out the trash everywhere. They just regarded the sightseeings as their houses, which cost a lot to clean it up. Besides, some one should write down their names on the trees and walls. People who wanted to leave their names whereever they went are always to punish in future.

Nevertheless, I also found some good examples, such as teaching tourists not to destroy the places of historic interests, helping clean up the environment,etc..I think we all need to teach more people not to hurt our precious nature. What we really need to do is protect them form destroying.

《黄河颂》中这样描写黄河，“黄河！你是伟大坚强，像一个巨人，出现在亚洲原野上，用你那英雄的体魄，筑成我们民族的屏障。”不错，作为“母亲河”，黄河曾它的乳汁哺育过我们。但是，随着工业的飞速发展，如今的“母亲河”已经是面目全非。例如，今年4月22日上午，黄河兰州段出现了大面积油污染，河面上出现了另人作呕的黑油。到下午，被污染的河水已近90公里。虽然此事已引起了国务院总理温家保的重视，且责任者已受到处理。但“母亲河”遭受类似污染已不止一次，她也不再是人们心目中那么清澈，透明的大河了。通过这次事件，我不得不进行思考：环境污染已经成为这个信息化时代最令人头疼的问题之一。

不仅我国，环境污染也同样存在于世界其它国家。例如，近几年来，动物变异现象时有发生，比如在印度洋的圣诞岛上，栖息在树林深处的上亿只红蟹，突然间如红地毯般覆盖了全岛。岛民们惊恐万分，直到红蟹腿去，才敢出家们。此外，美国佛吉尼亚洲到新泽西的沿岸，曾发生过200多头海豚陈尸海滩的事，这些死去的海豚大都十分消瘦，衰弱。甚至有些还患了肺炎，这显然是一场瘟疫造成的。

难道这一切都是天灾****吗？不是的，有科学家指出，这一切的罪魁祸首就是自诩为文明的人类。在日本，人驯养的猿猴中总不段的生出奇形怪胎，原因就是人工饲养的大多数都是被喷洒农药超标的食物。有些国家的猫有水银中毒现象，这些中了毒的猫就像醉鬼一样左摇右摆，站不稳。有的身体突然抽搐，震颤。经考证，最终原因是由于它们的主任用含有污染物质的鱼内脏喂猫。更另人触目惊心的例子，1986年，苏联，切尔贝尔核电站爆炸所造成的核泄漏，使附近农场的猪，牛不断生出没头没脑的怪胎来。

人类对环境的肆意污染，对生态的破坏，已招至了应有的报应，一系列的事实已经预示：如果人类不尽快停止污染环境，那么发生在动物身上的悲剧，也终将在人类身上重演。所以，人类应该拯救自己，从现在开始尽可能的保护环境。

环境污染大致分为“陆地污染”“水源污染”“空气污染”和“噪音污染”四种。

对于“陆地污染”，主要污染源是成千上万吨形形色色的垃圾。在处理垃圾时，可将能回收利用的进行加工以达到循环利用的目的。而不能回收利用的垃圾，特别是带有辐射性的垃圾，可将其在不污染海洋的前提下深藏在海底，以减弱对人类的危害。对于水污染，可以制定相关的规定来约束人们的行为，保护水体。“空气污染”应该需要更多人加入到植树造林的行列中来，为城市了、空气的净化出一份力。“噪音污染”应该用隔音材料将住宅区和公路隔开。也可与施工单位进行协调，给机器装上消声器。

只要我们动起来，相信不久的将来，地球将重现往日的绿色。保护环境就是拯救人类。人类将无愧于子孙后代。
