青少年很喜欢玩电脑游戏，一些人甚至旷课，他们在街上到处晃荡，去到网吧里面，沉浸在电脑游戏里面。我们都知道，网吧对于青少年来说不是一个该去的好地方。第一，网吧里面有形形色色的人。据报道，很多事故发生在网吧里面，一些人彼此间打架，然后砍人，甚至有人死掉。这是多么危险啊。第二，青少年相对比较天真，他们可能会在网吧里面收到坏人的诱导，也有可能被坏人绑架到别的地方，永远不能再回家。网吧对于青少年来说不是一个安全的地方，所以他们应该学着保护自己，远离网吧。

How to protect the environment

Good environment can make people feel happy and fit . To improve the environment means to improve our life.

We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.

Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了！所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢？只有慢慢的排队，慢慢的等！

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐！国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢？在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢？做了也只是少数罢了！根本没有从主要原因抓起！你看，黄河的水不是还在被污染吗？工厂不照样还在污染大气吗？抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗？没有！即使做了也只是做样子罢了。环境不是照样还在被污染吗？

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染！国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢？各种灾难不还是照样在发生吗？我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本！所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们

The word "college student" is used in most people to highlight the sparkle of the garland, how many people envy, and how many people want to have it!

Since college is such a thing that can change fate, many people think of college students "should". As more and more college students, college students did not seem so popular over the years, even when looking for a job, where the starting point is not higher than others, but this kind of idea.

Indeed, the number of college students is more than a year, a year employment difficult year after year its a question of reality, in the tide of market economy, how to face the society accept vocational selection, out of their way is before each choosing a career is a big exam. In the ordinary peoples eyes to wash the feet is the people to do the errand, especially now some of the bathing place business is improper, is subject to the secular prejudice. A college student to lay down their own shelves, do something that makes people do not understand the work, which in addition to using the learned knowledge in practice, more college students is faced with the severe employment situation, based on reality, tailored for take a way can reflect their own value.

But li didnt do it. She chose a career that didnt fit her own identity -- a foot wash

In some peoples opinion, labor is the difference between high and low, so when it happens, it will cause a great social explosion and become an eye-catching thing.

Indeed, the decades of hard work have yielded a so-called "humble" profession!

But I dont think that anyone has equal dignity, no matter what their social identity is. Society cannot see which profession, every profession has every occupation effect!

Cleaner -- often seen, but, have you thought about it? Without their diligence, what is the beautiful environment now?

Window washers - often demeaned, but, have you thought of it? Without their sacrifice, what is the bright vision now?

......

All in all, the people who work for every job are a good example of society... At least they serve the people with their own sweat!

There is an ideal "choice of door to the door", there is also the choice of "high school is low", and the choice of self-employment, no matter what choice do not want to overreach, should seize the opportunity. In order to start from the actual situation of society and myself, we should make a point of reality, which is only the condition, and the interior should be the key. Choosing a career may not necessarily be the case, but its up to you to grow. If you want to do well in your career, you will have a sense of perseverance and dedication to achieve your goals and social recognition.

So, career choices dont necessarily have to be so big! Live a wonderful self!

There 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. 环境问题的英语作文篇二

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

Pollution: An Increasing Concern in China It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc. To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. Whats more, the media should play an important role in implanting a sense of environmental consciousness into peoples mind. If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

[环境污染英语作文参考

关于英语环境保护作文结尾要如何写呢？下面是小编整理的英语环境保护作文结尾事例，希望能给大家带来帮助。

文章结尾的作用是概括全文内容，进一步强调或肯定文章的中心思想，使文章意义表达得更加深刻。

文章结尾的形式也是多种多样的，常见的有以下几种：

1、首尾呼应，画龙点睛

在文章的结尾，把含义较深的话放在末尾，以点明主题，深化主题，起到画龙点睛的效果。如“I Cannot Forget Her” (我忘不了她)的结尾：

After her death, I felt as if something were missing in my life. I was sad over her passing away, but I knew she would not have had any regrets at having given her life for the benefit of the people.

2、重复主题句

结尾回到文章开头阐明的中心思想或主题句上，达到强调的效果。如“I Love My Home Town”(我爱家乡)的结尾：

I love my home town, and I love its people. They too have changed. They are going all out to do more for the good of our motherland.

3、自然结尾

随着文章的结束，文章自然而然地结尾。如“Fishing”(钓鱼)的结尾：

I caught as many as twenty fish in two hours, but my brother caught many more. Tired from fishing, we lay down on the river bank, bathing in the sun. We returned home very late.

4、含蓄性的结尾

用比喻或含蓄的手法不直接点明作者的看法，而是让读者自己去领会和思考。如“A Day of Harvesting”(收割的日子)的结尾：

Evening came before we realized it. We put down our sickles and looked at each other. Our clothes were wet with sweat, but on every face there was a smile.

5、用反问结尾

虽然形式是问句，但意义却是肯定的，并具有特别的强调作用，引起读者深思。如“Should We Learn to Do Housework?”(我们要不要学做家务？) 的结尾。

Everyone should learn to do housework. Don’t you agree, boys and girls?

6、指明方向，激励读者

结尾表示对将来的展望，或期待读者投入行动。如“Let’s Go in for Sports”(让我们参加体育运动)的结尾：

As we have said above, sports can be of great value. They not only make people live happily but also help people to learn virtues and do their work bettter. A sound mind is in a sound body. Let’s go in for sports.

文章的结尾没有一定的模式，可以根据表达主题的需要灵活创造。一般的习惯是，一些记叙文和描写文经常采用自然结尾的方法；但说理性和逻辑性较强的说明文和议论文则往往都有结束语，以便使文章首尾呼应，结构完整。

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。

We know,campus is for teachers and students to work,a place of learning,a good campus environment,can give us to feel fresh,beautiful feeling.Our campus although the area is not large,but the green is good,trees,birds sing and flowers give forth fragrance; outside the classroom,aisle posted at all times and in all countries of the famous quotes.We are trying to create a healthy,harmonious,stimulating environment,so that the students in the good environment by infection and nurtured,in influence character by environment,establish correct world outlook,outlook on life and values,so that everyone in a beautiful,clean,warm environment day by day grow up healthy,do a civilized citizen!

我们知道,校园是老师和同学们工作、学习的场所,优良的校园环境,可以给我们以心旷神怡、美好的感觉.我们的校园虽然面积不大,但绿化还算不错,绿树成荫、花香鸟语；教室外面、过道走廊张贴了古今中外的名人名言.我们都在努力营造一个健康、和谐、催人奋进的环境,使同学们在优良环境中受到感染与熏陶,在潜移默化之中树立正确的世界观、人生观和价值观,让大家在优美、整洁、温馨的环境中一天天健康地成长,做一名文明的社会公民!

Private cars have become an important aspect of people’s life in many parts of our country,especially in large cities such as Beijing,Shanghai and Guangzhou.While they bring much convenience to people,they are also widely criticized.

There are some arguments for owning private cars.In the first place,cars allow people to move around freely,whichgreatly improves our living standard.We easily drive cars for traveling.In second place,When we have something urgent to do,cars are quick than other vehicles in some extent.Last but not least,the car industry can boost economy by creating many job opportunities.

However,there are also many arguments against cars.First of all,they pollute the environment by emitting harmful gases.What’s more,cars cause a large number of traffic accidents,which bring great misery to their family.

As far as I am concerned,we should limit the number of private cars by providing better mass transportation and better service for the people.Everyone should sacrifice his or her own interest for the mass society.

In recent years, I find it easier to our resources dried up. All of these, because we have recently a lot of collection resources, leading to our mothers are dwindling.

What is the mother of all resources less and less? Is, of course, we humans excessive spoiling dont cherish, would cause such a serious result. Our earth forest area has reached 600 million hectares, the figure is due to our human previously has important sense to protect the environment, know that if you dont have a good environment, we wont be able to breathe to the light wind gently brushed the grass surface sweet taste. And now? Us that the earths forest area is still not arrived 6 hectares, this kind of situation, it is because we humans cut down trees and destroying forest without restraint, make almost fell by 1% in each of the forest area in the world, now our protection in the nature of the important consciousness is more and more shallow, dont take care of the objects around, as the forest is less, the first bite of the air we breathe is less and less fresh...

Is not destruction of forest resources, and our mineral resources. It is limited, now our production technology constantly improve, the accelerating speed and shortage of some minerals occurred, even dried up. Until then, we will always stay in the desolate landscape.

In the face of these, can see there are so many resources in we lost too much! We rely on resources too much! All around us, little drops of the resources are in decline, if lost it all, we will how to live! So, let us sincerely treat our mother earth, try to cherish, to cherish. If only use a small plastic bag, it should not be too!

Let us act, to defend the earth!

近几年来，我发现我们的资源越来越容易枯竭了。这些，都是因为我们最近大量的采集资源，才导致我们的母亲日渐枯竭。

是什么让我们这位母亲的资源越来越少了呢?当然是我们人类过度的糟蹋不珍惜，才会造成这样严重的结果的。我们的地球森林面积曾经达到了6亿公顷，这笔惊人的数字是由于我们人类以前有着保护环境的重要意识，深知如果没有了良好的环境，我们也就无法呼吸到微风轻拂过草面的甜美味道。而现在呢?我们地球的森林面积还不到了6公顷，这种状况，就是因为我们人类不加节制地砍伐树木和毁林开荒而造成的，使世界上的森林面积几乎每年减少了1%，现在我们的保护在自然的重要意识越来越浅，不爱护身边的一草一木，由于森林逐渐变少，我们呼吸的第一口空气也就越来越不清新……

还不止森林资源被破坏，还有我们的矿产资源。它是有限的，现在我们的开采技术不断提高，速度不断加快，使某些矿种发生短缺，甚至面临枯竭。到那时，我们将永远呆在荒凉的大地上。

面对这些，可以看出来我们失去的资源真是太多太多了!我们的依赖的资源也太多了!在我们身边，点点滴滴的资源都在减少，如果失去了这一切，我们将如何生活!所以，让我们真心地善待我们的地球母亲，努力去珍惜，去爱惜。哪怕只是多用一个小小的塑料袋，这也是不应该的!

让我们行动起来，保卫地球吧!

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.

尊敬的市民们：

你们好！

瑞安，是一个和谐美丽的大家园。热闹的街道，琳琅满目的商品；充满乐趣的乐园，洋溢着孩子们嘻嘻哈哈的打闹声；荡漾温情的家里，一家人坐在桌边有说有笑……但是，就在这个幸福美满的大家园中，却有一个十分严重的现象——污染环境！

草拼上随处可见的果皮纸屑，公路上大大小小的痰，恶臭的塘河，汽车的尾气……这些无一不是污染环境的行为。

人类是懒惰的。往前走几步，或许就是一个垃圾桶，却仍然要把垃圾扔到地上去；明明可以把痰包在纸巾里，再扔掉，却执意要吐到地上去……种种行为，让我们美丽的大家园——瑞安，变得伤痕累累，狰狞可怕，不再美丽壮观，和蔼可亲。

人类，难道还不觉悟吗？

那唐河来说，在几十年前，她还是一条清澈见底的母亲河，让人们在她的怀里钓鱼、洗澡、游泳，犹如一位慈祥的母亲，慈爱的望着自己的孩子。

但是，如今的母亲河是怎样的呢？肮脏、乌黑 、恶臭……人们不愿意再用塘河里的水，不敢下水游泳，更不敢吃塘河里的鱼……

母亲河在哭泣，哭泣人类为什么要这样对待她，难道人类就是这样忘恩负义、恩将仇报吗?她不懂，她做错了什么？

不，这位慈爱的母亲没有做错。导致这一切的，是人类的懒惰，那种毫无保护环境意识的心理。懒到把垃圾扔进塘河，懒到把工厂里的废水直接排到塘河里，懒到……

母亲河，一位养育我们子子孙孙的人类母亲，却亲手被自己的孩子糟蹋的千疮百孔。

人类，难道不感到悲愤、自愧吗？

对于保护环境，我想提几个建议：

1、节约资源：节水为荣，随时关上水龙头，千万不能浪费我们的水资源。

2、分类回收：不乱丢弃废电池、废塑料等垃圾、废物。

3、重复使用：尽量少使用一次性用品，多使用耐用品。如，不使用一次性性塑料和餐盒，减少白色污染。

4、爱护树木：植树造林，爱护我们身边的每一寸绿地身、每一株花草、每一片树木。

5.保护塘河：让所有的市民共同参与到保护塘河地行动中去，让我们美丽的温瑞塘河不再哭泣。

我的家乡————-安海，是晋南侨乡一座蜚声中外的文化古镇，现又以经济开放名闻遐迩。她钟灵毓秀，物产丰富，经济发达，令人向往。她历史悠远，文化流长，人才辈出，是一方神圣的文化宝地。著名的民族英雄郑成功一生的三分之二的时间，在这里汲取灵气。

家乡的灵源山，令人流连忘返。它风景如画，烟雾变幻，不仅是饱览泉南风光的最佳去处，而且是一座富有中国传统文化内涵的名山。站在顶峰，无限风光尽收眼底。

家乡的安平桥，一桥跨海五里，素有”天下无桥长此桥”的美称。它直如绳，平如砥，犹如长虹卧波，又似玉堑通天。桥下碧水澄清，一片片柔嫩的水草，一群群可爱的鱼儿小虾，簇簇树影。人在桥上，微风一吹，映在水里的身影跟着颤动起来，真是优哉游哉，别有一番情趣！

家乡不仅充满了湖光山色的自然美，而且洋溢着现代化的气息。恒安工业城拔地而起，安平开发区别墅幢幢，商业城里门庭若市。东大街两旁高楼林立，栉比排列，大有与天公试比高的气势。大楼上彩旗迎风招展，向你展示着当代安海的活力。走在街上，车辆如梭，行人如流，琳琅满目的商品令你眼花缭乱，目不瑕接。听！学校里每天书声琅琅，不知为祖国培育出多少人才啊！看！精神焕发的老人们相约在公园里跳舞、打太极拳，舒适地享受着晚年的欢愉生活。瞧！家庭主妇们兴致勃勃地学起英语、电脑，为更好地投身于家乡的建设积蓄力量……

今天，家乡乘着改革的春风飞速前进。在党的好政策的引领下，在家乡人民的奋斗下，在侨胞们的热情关怀下，家乡的经济展翅腾飞，并成为凝聚海峡两岸同胞和海内外乡亲情谊的一条纽带，为促进祖国统一大业做出了积极的贡献。

明日的家乡，必将乘风破浪，更上一层楼。未来的家乡四季吐芳、绿草茵茵、环境优美。条条笔直的水泥路直通小镇的各个角落；每辆车的尾部都会安装上一个“烟气消除器”，把车辆排放出来的烟气，点滴不遗地吸收起来；工厂里的废气、废水、废渣得到了最好的处理；通讯设施、交通条件也都要比现在发达许多；人民安居乐业，有如生活在世外桃源。

真美啊，安海！我要歌颂这已有八百年多年历史的家乡，我要赞美这“四时花不谢，八节春长在”的家乡，我更要把我的智慧、把我的汗水撒在这片肥沃的土地上，为安海明天的新辉煌尽一份力量！

爱我家乡，建设古镇！

[家乡的环境污染初三作文

同学们：

你们好!

我们天都在校园里生活、学习，校园就像我们的家。每天我一走进校门，首先映入眼帘的是一片片绿油油的草坪;一颗颗高大挺拔的树木;一只只歌唱的小鸟;还有那高高耸立的教学楼，组合成了一个美丽的大花园。

虽然我们的校园是如此美丽可爱，但一些同学却不懂得珍惜，破坏环境的事时有发生。

一次，正是桂花开放的季节，风中含着桂花的清香，飘荡在校园的每一个角落。可一些同学不但不保护它，还无情地用脚踢树干，桂花纷纷从树上飘洒下来。一些桂花洒落在他头上，他一抖，桂花又飞落到地上，我去制止他，并把桂花扫进草丛中，让它们变成肥料去滋养土地。可他不但不听，反而带动了其他人一起踢，我只好无奈的摇摇头。

校园里不仅有污染环境的现象，还有许多浪费的现象。课间，有许多同学把老师放在讲台上的粉笔偷偷地拿来掰成几段，当成砸人的武器。更让人厌烦的是有人将粉笔压成粉末，夹在纸里，趁你不注意突然拍一下，那粉末就喷出来，散在空气中，让人喘不过气来。

为什么同学们会这样做呢?原因就是学生保护环境的意识太差。为了把我们的校园建设得更加美丽，为此，我提以下建议：

1.利用广播对文明行为进行表扬，号召同学们来保护环境。

2.开展保护环境、珍惜资源的活动，让同学从中知道保护环境、人人有责的道理。

3.利用黑板报等来宣传环保。

4.每年植树节时让每个同学亲手种树，品尝一下植树的辛苦。同学们，行动起来，让我们齐心协力，共创更加美丽的校园。

Spring, my hometown, green grass and flowers are in bloom. Out of the tree branches, birds singing in the merry. Looking around is the continuous mountains, mountains and rolling hillsides in the spring, as if a domesticated hen the carpet, until the sky. Graceful flowers blossoming in a dotted mountains, attract colorful butterflies; in the depths of the mountain is the terraced rows of shapes, by definition, is the same as the stairs rice; a winding path to article rice into the ever-changing shape, some like crescent, and some, like boats, some as sickle ... ... in the spring, when seedling growth, fresh green color of the home that add still more beautiful.

Summer, sun spit fire, but the hills in the home full of trees, in the shade of the shelter, the very cool; also known bird burst into song. Kind of ripe watermelon in the mountains, home of the watermelon usually round and bright, and that the air moon, as round; cut, I saw a bright red flesh, sweet and delicious; black seeds, like the eyes of swarthy .

Autumn is a golden rice, breeze, rice started singing a harmony of the song, when hard-working farmers are harvesting rice; rice harvest of the cheerful sound of voices and interwoven success of the harvest of the symphony .

Winter, although the trees have been dying, but is everywhere in the roadside grass and wild flowers, which stand at attention in the cold. They tell you: "If winter comes, can spring be far behind?"

This is my beautiful hometown, my favorite home.

春天,我的家乡,绿草和鲜花盛开。树枝,鸟儿在快乐的唱歌。环顾四周是连续的山脉,山脉和滚动在春天的山坡上,仿佛一只家养母鸡地毯,直到天空。优雅的花朵盛开在虚线山脉,吸引色彩斑斓的蝴蝶,在山的深处是梯田成排的形状,根据定义,楼梯大米一样,蜿蜒的道路条大米到不断变化的形状,有些像新月,和一些,像船一样,镰状……在春天,当幼苗生长,鲜绿的颜色,添加更美丽。

夏天,太阳吐火,但家里的山的树木,在树荫下的避难所,非常酷,也称鸟闯入的歌。成熟的西瓜在山里,家里的西瓜圆又大,空中的月亮,是圆的;,我看见一个明亮的红肉,香甜可口,黑色的种子,像黑的眼睛。

秋天是金大米、微风、大米开始唱这首歌的和谐,勤劳的农民们收割水稻,水稻收获的愉悦的声音声音和交织的成功收获的交响曲。

冬天,虽然树木死亡,但在路边到处都是草地和野花,立正的冷。他们告诉你:“冬天来了,春天还会远吗?”

这是我美丽的家乡,我最喜欢的家。
