+ 加入清单去年冬天一场大雪过后,我和爸爸妈妈去爬浮山。一进浮山就觉得一股清新的空气迎面扑来,抬眼望去大大小小的山头上白雪茫茫,雪的底下隐约露出一些绿色的树叶、褐色的土地……就像一副美丽的风景画。
咦?那里在干什么?很多人在那里排队,队伍好长,而且每个人都带着大大小小的桶?我拉着爸爸妈妈走进去,呵!原来他们都是在排队等着接这里的山泉水。这水能喝吗?妈妈告诉我,因为浮山属于崂山山脉,空气、环境都很好,污染也少,这里的山泉水特别好喝,所以附近很多人都从这里打水回家喝,甚至有的人从很远的地方特意过来呢!我特意喝了一口,真甜,比家里的自来水好喝多了。
离开了泉眼,我们继续往山里走,我发现在路的两边总能发现一些食品袋、饮料瓶,太可恶了,是谁在破坏这美丽的浮山!肯定是一些不讲文明的人,他们随手乱扔垃圾,不仅破坏了环境,造成了白色污染,又影响了草木的生长。大家都这样,以后浮山的山泉水还能喝吗?浮山还会是像今天这样美丽吗?
我记得爸爸跟我说过:因为经常有人在高速公路上乱扔垃圾,害的环卫工人不得不一次又一次的冒着生命危险去捡,后来就有一位环卫工人因为在高速公路上捡垃圾被撞死了……

篇1:环境保护一封信
全文共 539 字
+ 加入清单亲爱的大自然:
你好!我是一名普通的小学生,对您充满了感激。可是,我还需要代表人类对您说一声对不起,也对您有一些意见。
大家都知道,是大自然给了我们美丽的生活环境。是您带给了我们青青的树,带给了我们嫩嫩的小草……您带来了许多,使我们能健康,快乐地成长。看到这里,我心存感激,但也心存惭愧!我要代表人类对您说一声:“对不起!”
原本,您带来了许多美丽的景物。可是人类的生活越来越好了,越来越舒适了,大家的保护环境的意识越来越淡了:我们大量砍伐树木,“制造”沙漠;滥用化学药品,排放有毒物质,成为破坏土壤、杀害小草小花的“凶手”;人们随地乱扔垃圾,将一条条清澈的河流变为“臭水沟”;人们随地乱吐痰,我们的地球逐渐变得肮脏不堪……人们“恩将仇报”,将大自然的杰作统统毁掉,这跟“侵略者”有什么两样呢?我再次向您表示歉意!
但是,我认为您未免有些太无情了:在2008年5月12日下午,您忍不住了!您一颤抖,使四川汶川发生了8级大地震;有时您大发雷霆,怒不可遏——一会儿台风频繁袭来,一会儿暴雨引发洪水,一会儿寒流导致暴雪。我想:可能您也是为了引起人们的注意——人类,一定要保护环境啊!我只是希望您能珍惜您的身子,不要为了发泄、发怒,连累了更多的人——让很多人家
园毁灭,财产损失。
祝您越来越美丽!

+ 加入清单从我家门口到火车站之间有一座桥,桥底下有一条叫作“保兴垾”的水沟。那儿的水面上随处可见塑料袋、方便盒等垃圾,水黑呼呼的,发出一股难闻的气味,每次我从那走过的时候都捂着鼻子快速地跑过去。特别是到了夏天,“保兴垾”的臭水滋生出很多蚊虫到处乱飞,住在附近的居民怨声载道。
为了彻底改造 “保兴 垾 ”,政府把它列为重点工程。他们把 “保兴 垾 ”里的淤泥挖去,铺上大理石和鹅卵石。等水变得清可见底,碧得发亮时,再在里面种上水草,撒上鱼苗,让 “保兴 垾 ”远离污染。我想,改造后的 “保兴 垾 ”变成了一条远近闻名的小河,小河旁那绿得没有一点儿杂色的蕨草,那悄悄开放着的花朵,给 “保兴 垾 ”编了个五彩的花环。
我从 “保兴 垾 ”这件事情中知道了保护环境的重要性,更体会到保护环境要从我们自己做起,从每一件小事做起,从身边的一点一滴做起。当看见别人乱扔垃圾、到处乱涂乱画、乱倒乱排废水、污水时,及时制止他们,不让他们污染环境。如果我们每个人都坚持管住自己的手、脚、嘴,那我们的家乡——芜湖会变得更加美丽,更加富饶。

+ 加入清单My Views on Environmetal Protection
Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.
If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.
Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

+ 加入清单我妈妈是一个很讲卫生的人,她特别讨厌脏,有一次,我妈妈见小区的垃圾桶太脏,就打电话给房东,让房东去了。我妈妈看见一个人从汽车上扔下垃圾,就骂他个不停,我妈就是一个特别爱干净的人。
有一次,我去上课外班,来的很早,到了教室,一片狼藉。我看不下去,就开始动手了,拿了工具就开始,也不知道为什么,越干越起劲。这是谁这么可恶,在教室都这么不讲卫生,何况在外面,也许会随地吐痰、乱扔垃圾、乱扔电池。想想就气,中国人为什么不可以像外国人一样,保护大自然,保护环境呢?
我希望人们在往后的日子里,保护环境、节电、节水、低碳,让我们在健康的环境下生活,超越外国人的素质,让我们的素质更上一层楼,让我们的地球更美丽,让别国人不再小看我们。
我们应该多种树,少乱砍树木,多绿化,少建工厂,不要光动嘴皮子,赶快行动起来吧!

+ 加入清单今天星期一,我们学校要升旗。我起床后便匆匆忙忙出了家门。
一出门,我就惊呆了:门口堆满了比珠穆朗玛峰还高的垃圾,臭气熏天!绕着“垃圾珠穆朗玛峰”的是一个个深不见底、通向地心的矿坑,一股股刺鼻的热气从底下冒上来。仰头望去,天上灰蒙蒙的,掺杂着黄沙,太阳早已不见了踪影,我小心翼翼地绕过一个个矿坑,来到海河边,海河的水都哪里去了,只看到河床里到处是布满垃圾的污泥,弥漫着刺鼻的臭气。
我匆匆赶到学校,学校的电子屏上写着:“请各位同学跟随自己的家人,尽快到安同路原址上的广场乘坐逃生舱。距离末班逃生舱出发时间还有2小时。”我火速返回家,把这事告诉了家人。家人们迅速地收拾好行李,向安同路出发。1小时后,我们乘坐末班逃生舱离开了地球,来到了火星。我们在火星上安了一个新家。一天,我乘坐飞行器前往冥王星找同学。半路上,我一直看着我熟悉并热爱的地球,突然,这个曾经美丽富饶的星球,一下子变成一个大火球,随着几次剧烈的爆炸,地球消失了。“不!”我大声地哭喊着,“地球,我不想失去你!”
我蹭地一下坐了起来,脸上还挂着泪水,原来这是我做了一个噩梦!
我半天没有缓过神来!还好,这只是一个梦。但回想起来,我们身边的人们却一直在尽情而又贪婪地浪费着地球资源,破坏着地球环境。不是吗?你看,各种矿场、化工厂以及滥砍滥伐,无情地破坏地球环境;马路上汽车成灾,尾气排放超标;人类为了私欲发动战争,全年地球没有战争的日子只有25天,地球已经千疮百孔……
我曾经跟着爸爸妈妈去过世界上很多美丽的地方,那蓝色的大海,绿色的森林,辽阔的草原,弯弯的小河,令我无比留恋,我也憧憬着长大后去更多的地方,去探知无尽的未来。但这个噩梦突然让我有一些恐慌,假如地球真的遍体鳞伤,被人类毁坏,那么所有的一切不复存在,人类将陷入万劫不复之境地。
要想留住地球,就要从小事做起,从我做起。我们要成为环保小卫士,一定要把地球的病治好。做到不随地乱扔垃圾、要爱护身边的动植物、要节约用水、要绿色出行等等。虽然这些都是小事情,但我相信,只要坚定地做下去,一定能使我们的地球更加美丽富有。
因为,我真的不想和地球说再见。

+ 加入清单我家住在长安新村,那是一个美丽的新村。它犹如一个温暖的大家庭,让住在那里的人们每天生活得快乐舒适。
每当春天来临的时候,杜鹃花含苞怒放,一簇簇,一丛丛,多么像一个个紫色的小喇叭呀!这些“小喇叭”也会准时吹喇叭,可神奇啦!小喇叭里有一根根“白头发”,那是它的蕊丝,真是美丽极了!初夏来临的时候,栀子花苏醒了,有的才展开两三瓣,有的全部展开了,有的还是花骨朵儿……那香味沁人心脾,真醉人!早晨,我能听到小鸟在枝头唱歌,甚至连野鸽子也会来我家阳台的玻璃窗边做窝。看着这一切,我太开心啦!
但就在这些美丽的杜鹃花和香气扑鼻的栀子花丛底下,出现了很多臭臭的垃圾。那是居民为了贪图方便,随手扔在那边的呢!日复一日,垃圾也越来越多。两年前,突如其来的洪水闯进了我们的小区,花丛里的垃圾都浮出来了。洪水过后,我们的新村臭气熏天,蚊蝇成群,简直成了人间地狱。
政府决定改造我们的小区。他们把那些带有垃圾的绿化带都填平了,铺上了一层水泥,小区变得更加干净了,小区里还增添了许多垃圾筒。居民看着这一尘不染的地,都不忍心随便乱扔垃圾,而是放进了新的垃圾筒。我们的新村一下子变得干净整洁,我们都喜欢它。我相信,只要我们人人爱护环境,我们的家园定会变得更加美好!

+ 加入清单环境保护对我们来说并不是一个新问题,我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人,虽然不可能都直接从事环保工作,但我们完全可以从小事做起,从我做起。
Environmental protection is not a new problem for us, our government has already made clear the goal of governance. As every ordinary people in real life, although not directly involved in environmental protection work, but we can start from the minor matter, begin from me.
当看到洗手间的水龙头在滴水时,是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?一件件小事虽然都很不起眼,但却体现我们究竟具备了多少环保意识。
When you see the Restroom faucet in water, Shi Bushi can raise close? When the battery is exhausted can classified processing rather than throw it away? When shopping can consciously do not use thin plastic bags? A trivial thing though is very humble, but we have the number of environmental consciousness.
回收1吨废纸可再造出800千克好纸,可以挽救17棵大树。回收20个废餐盒可以造出一个漂亮的笔筒。回收一个玻璃瓶节省的能量,可使灯泡亮4个小时。回收1个铝罐就等于节约了半个铝罐的石油。所以我们应将垃圾分类安放,由有关部门回收后再生产再利用!
Recycling 1 tons of waste paper can be recycled 800 kilograms of paper, can save 17 trees. Recovery of the 20 waste boxes can create a beautiful pen. Recycling one glass bottle to save energy, can make the light bulb for 4 hours. Recovery of the 1 aluminum cans is equal to saving half an aluminum cans of oil. So we should put garbage classification, by the relevant departments after the recovery of reproduction!
只要我们从自己做起,从小事做起,大家共同努力,持之以恒,就一定能为社会、也为自己留下一片碧水蓝天,我希望人人都能自觉保护环境,让我们的生活环境更加美好。
As long as we start from ourselves, from the little things, we work together, will be able to persevere, to society, but also for myself a blue sky, I hope everyone can consciously Protect environment, to make our living environment more beautiful.

+ 加入清单Our environment is getting worse and worse now. People throw their garbage here and there. Factories make more and more dirty water that has polluted the rivers and lakes. What should we do?
We must find ways to stop pollution. Waste water must be cleaned before it is poured into the river. People shouldn‘t throw away rubbish here and there. We should pick up the garbage around us. We‘d better plant more trees.
I‘m sure if we take care of our environment, our world will be more beautiful!
现在我们的环境越来越糟。人们把他们的垃圾这里和那里。工厂使越来越多的脏水污染了河流和湖泊。我们应该做些什么呢?
我们必须找到方法来制止污染。废水必须清洁之前倒进河里。人们不应该到处扔垃圾。我们应该捡起身边的垃圾。我们最好种植更多的树木。
我相信如果我们照顾我们的环境,我们的世界将会更美丽!

+ 加入清单天上的云哭了,是灰尘夺走它洁白的外衣,侵入她的身体;海里的水哭了,是工厂的废水污染他的肌肤,融入他的血液;山上的树哭了,是人类看中它的价值,伐走它的枝干!地球母亲哭了,是人类的自私赶走了他的微笑。
现在,各种各类千奇百怪的垃圾已经侵蚀了整个社会,在地上的垃圾袋,在草坪里的饮料罐,在花坛上的纸屑,乱飘的垃圾袋,在垃圾箱旁的一堆垃圾……为社会又换取了一个新的“面貌”,而这个“面貌”的最佳制造者是谁?是人类。如果让国外的人们看见还已为我们在开垃圾展览会呢!
雨果曾说:”大自然既是善良的慈母,同时也是冷酷的屠夫。"近年来,人类由于对环境不够珍惜,随心所欲,滥伐林木,生存环境遭到了严重破坏,绿色是大自然赠与我们人类的宝贵财富,人人都渴望拥有一个美好的家园,人人都想要地球不再哭泣!“节约用纸”我们每个人每天都在用纸,用各种各样的不同类型的纸。你每天要用多少张纸?一张纸从何而来?纸是由树“变”来的。一棵树往往需要长几十年才能被人类利用。人类是无情的,电锯声中,几十年长成的大树轰然倒地。那些木材,运往造纸厂,变成了一张张纸。纸给人类带来了方便,但同时给森林造成了极大的影响。如果没有树木,就没有氧气,那人类也就无处安身。
我建议:
1、从现在做起,我们每一个人都要自觉做到不随便乱扔垃圾,不随地吐痰。
2、爱护树木,花草,不要随便砍伐,践踏绿色树木和草地。
3、爱花鸟类,保护鸟类,保护动物。
4、不要使用塑料袋,减少白色污染。我们这个城市如果每天每人使用一个塑料袋,每天将产生5吨塑料垃圾!
5、不使用一次性筷子。或许你不曾想过,哪怕我们每一个人这辈子只用一双一次性筷子,全国也得砍掉15万棵生长了20年的大树。我国每年因生产一次性筷子消耗的林料就达200万立方米,这足以引发长江洪水泛滥!
从自己做起,从小事做起,多一片绿叶,多一份温馨;多一份关爱,多一份呵护。让我们一起:珍爱绿色,珍爱我们共有的家。携手保护我们的家园,自然会给人类应有的回报。
绿,生命的颜色;绿,环保的颜色。有了绿色,便有了清新的空气;有了绿色,便有了沁鼻的花香;有了绿色,便有了地球母亲灿烂的微笑!
每年的6月5日是世界环境日。每个人都可以通过选择绿色的生活方式来参与环保:,减少污染;绿色消费,环保选购;重复使用,
绿,生命的颜色;绿,环保的颜色。有了绿色,便有了清新的空气;有了绿色,便有了沁鼻的花香;有了绿色,便有了地球母亲灿烂的微笑!

+ 加入清单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.

+ 加入清单【第一篇】
放眼望去,有的只是凹凸的地皮,大片大片的树林遭人砍伐,变成人们生活上的木制品。人们只为一己私利,使成群的动物流离失所,奔向它方。这并不是虚假的幻想,这是血淋淋的事实。
曾几何时,世界上大批的动植物遭到灭绝,还有许许多多的动植物濒临灭绝,这都是为什么?这都是因为人类乱伐树木,破坏了生态环境,这才是根本原因。
土地资源是三大地质资源(矿产资源、水资源、土地资源)之一,是人类生产活动最基本的资源和劳动对象。人类对土地的利用程度反映了人类文明的发展,但同时也造成对土地资源的直接破坏,这主要表现为不合理垦植引起的水土流失、土地沙漠化、土地次生盐碱化及土壤污染等,而其中水土流失尤为严重,乃当今世界面临的又一个严重危机。据估计,世界耕地的表土流失量约为230亿吨/年。
有人认为酸雨是一场无声无息的危机,而且是有史以来冲击我们最严重的环境威胁,是一个看不见的敌人。这并非危言耸听。随着工业化和能源消费增多,酸性排放物也日益增多,它们进入空气中,经过一系列作用就形成了酸雨。
赤潮虽然自古就有,但随着工农业生产的迅速发展,水体污染日益加重,赤潮也日趋严重。我国自1933年首次报道以来,至1994年共有194次较大规模的赤潮,其中60年代以前只有4次,1990年后则有157起。石油类污染对水质和水生生物有相当大的危害。漂浮在水面上的油类可迅速扩散,形成油膜,阻碍水面与空气接触,使水中溶解氧减少。油类含有多环芳烃致癌物质,可经水生生物富集后危害人体健康。二氧化硫主要由燃煤及燃料油等含硫物质燃烧产生,其次是来自自然界,如火山爆发、森林起火等产生。二氧化硫对人体的结膜和上呼吸道粘膜有强烈刺激性,可损伤呼吸器管可致支气管炎、肺炎,甚至肺水肿呼吸麻痹。短期接触二氧化硫浓度为0。5毫克/立方米空气的老年或慢性病人死亡率增高,浓度高于0。25毫克/立方米,可使呼吸道疾病患者病情恶化。长期接触浓度为0。1毫克/立方米空气的人群呼吸系统病症增加。另外,二氧化硫对金属材料、房屋建筑、棉纺化纤织品、皮革纸张等制品容易引起腐蚀,剥落、褪色而损坏。还可使植物叶片变黄甚至枯死。
【第二篇】
最近我读过一本好书,叫作《我的野生动物朋友》。这本书主要讲法国小女孩蒂皮,她从小跟着父母在丛林中长大,野象、驼鸟、变色龙、牛蛙、豹子、狮子、狒狒……最终都成为她最好的朋友。这本书还我们告诉:尽一切努力爱护我们周围的环境,人与自然是个和谐统一体。这本书给我一个很大的启发:我们要爱护环境,不能让我们未来的环境遭受毁灭性的破坏。爱护环境,利己利人。
当我看到“科学发展、爱护环境”这八个字时,东台的环境新景一一浮现在我的眼前。最近几个月,东台的道路都在扩建中,虽然在施工时,会给行人和车辆带来不便。但是大家都很理解,爱护周围新建的设施以及工地上的建筑设施。每一次,我和妈妈从商场回家时都小心翼翼地经过施工地,从不违规。我听说还要东台的一些休闲场所,建了人工喷泉、水上电影大屏幕、文化长廊等,东台的人们正在使用了高科技来改善我们的生活环境。保护环境的作文400字
在各种公共场所,人们自觉地把瓜果皮纸屑分类扔进垃圾箱里,这也体现在我们东台人正在爱护周围的环境。在公园里,春天到了,万木吐绿,空气清新。各种各样的花朵竞相开放,有黄灿灿的迎春花、粉红的桃花,雪白的梨花,特别是色彩斑斓的蝴蝶花,像一只只蝴蝶在翩翩起舞。在小区里,一进大门,满眼都是绿色的树木,有松树,柏树,广玉兰、香樟树、爬山虎……就连小区的名称都是用绿色灌木拼成的,就是这些花草树木,引来了成群结队的小鸟们到这里来“散步”、“游玩”……
从常住的居民到来来往往的行人,都在自觉保护身边的环境。我相信,未来的东台将会变得像《我的野生动物朋友》种描绘的那样,人与自然、人与动物浑然一体!

+ 加入清单The sun summoned the planet in the solar system to open an emergency meeting, the theme is to save the planet. The sun to see everyone to the Qi, and clear the clear voice, said: "The stars, our good sister earth has been at stake, the doctor said that her blood is toxins, the body of nutrients is also depleted, in this way "The moon says," In recent years, mankind has mined a lot of oil, minerals, wood and other materials, without protecting the environment, and the earths sister is not sick. "Saturn says" Way, we save the earth together! "" Well! "The stars have promised.
After the stars go back, have heard of human beings looking for a second home, so have made an appointment, never the second home of mankind, have also thrown away the conditions may be human use. For example: the moon threw away the oxygen, Saturn threw away the appropriate temperature, Mercury thrown away ... ... Finally, the human consciousness that the earth is the only human home, carried out to protect the Earth action.
300 years later, the sun also held a meeting, the earth also participated, she looks beautiful, green skin, clean blood, more importantly, she becomes healthy, the moon said: "sister, see you now So happy, I am happy for you. "Mercury said," Sister, see you now so beautiful, I am a little jealous. "Earth said:" Thank you all for my sacrifice so much, I am now healthy, or Thank you all, thank you, "said the sun," the stars, after this action, humans have recognized the importance of the earth, and I declare that the rescue of the earth is a success.
Friends, the mother of the mothers disease though good, but also need to continue convalescence, and now, let us work together to the earth dressed as the most beautiful planet in the universe.
There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.
Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."
Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

+ 加入清单Work and play do not contradict each other; in fact, they complement each other. As the saying goes, "All work and no play makes Jack a dull boy." A life burdened with work leads you nowhere, for you would get tired and bored with your daily routine work. On the other hand, proper recreation will relieve the tension and discomfort of our monotonous life because it offers you various ways to let out your pent-up emotions.
What I usually do to relax after school is jogging and seeing movies. Usually I dont spare time for exercise, but I value the physical education class at school. Jogging several rounds in the field certainly relieves the days pressure. On weekends, Ill catch the morning movie for my visual enjoyment. I feel revived and energetic for another weeks work-load.
工作与娱乐并不互相冲突,事实上,它们之间的关系还相辅相成。有句格言说:整日工作而没有休闲娱乐,会令人变得沉闷乏味。」被工作重担压得喘不过气来的生活,将使你一事无成,因为你将对一成不变的例行公事感到厌烦。由另一方面来说,适度的娱乐活动能提供各种管道,来渲泄你被压抑的情绪,减轻单调生活中的紧张与不悦。
放学之后,我最常做的休闲活动,便是慢跑与看电影。通常我并不特地拨出时间来做运动,但是我很重视学校的体育课。在操场上慢跑几圈,无疑地可以减轻一天的压力。在周末时,我都去看早场电影,享受视觉飨宴。如此一来,我将有如再生般的充沛活力,去面对下一星期的工作量。

老师带着我们走进了大自然。大自然风景如画,秋香扑鼻。同学们赞叹道:“大自然好美呀。真的是活生生的一幅美丽的图画。同学们边走边欣赏着大自然这美丽的风景。同学们都走累了。正好到了中午吃饭的时间。小兔子老师说:“同学们找一个凉爽的地方,我们开始吃饭吧!
小狐狸吃完东西就放在了地上,老师说:“同学们都吃完了么?吃完的咱们就走吧!同学们异口同声的说吃完了,可以走了。老师和同学们都走远了。小狗走的慢,看见小狐狸脚下的垃圾,大声喊道:“老师,老师,小狐狸脚下有纸屑,你们快过来。老师说好的。这时候小狐狸自言自语的说:“又被他们发现了》”老师把小狐狸喊过来对它说:“小狐狸同学不要乱扔垃圾,会影响环境的,我们每一个人都应该保护环境,保护我们共有的家园。给我们创造一个好的学习,生存的环境。
小狐狸低下头很愧疚的说:“谢谢老师的批评,以后我一定不乱扔垃圾了,我要保护环境,要给地球一片绿色的外衣。"老师竖起大拇指说到:"真棒,说的真好,我们每个人都应该保护我们的环境,也要监督破坏环境的人,叫他们积极改正。”
有了小狐狸的例子,大家都知道保护环境了,给森林一片绿色,给地球一片绿色。

+ 加入清单旅游,是许多人的爱好。游览祖国的大好河山,饱览名胜古迹的同时,我们也在不断的增长知识。不用说,我就是一个旅游爱好者。今年寒假,我又登上了家乡的南长城。
三年前的南长城十分雄伟,从烽火台向下望,可以看见碧波荡漾的东湖和数不胜数的各式各样的楼房。三年后的南长城,又会是一番怎样的景象呢?怀着无限的遐想与期盼,终于来到了长城脚下——崇和门。向前望去,可以看见长城蜿蜒盘绕在山间,犹如一条长龙。虽说它们没有北京的长城那么长,那么壮观,但也非常雄伟,给我一种肃然起敬的感觉。
登上长长的台阶,在不远处望见了第一个烽火台。妈妈一边欣赏着长城两岸的风景,一边给我讲历史典故。这是我更加了解了这座历史悠久、风景如画的南长城。
一路的攀爬,使我感受到了长城的变化。总的来说,一切几乎都没怎么变,但我看到长城上有许多的垃圾。这,使我感到愤怒:华夏儿女的祖先千辛万苦、风餐露宿才打下了天下。每一个名胜古迹都有着它独特的风景和一个个古老的故事与传说。如今,人们不但没有好好地保护它们,还加以破坏:在城墙上乱涂乱刻,随地吐痰、乱扔垃圾。作为中国人,作为炎黄子孙,难道不感到羞辱吗?
作为新世纪的少年,我们应该更加注重环境的保护。20__并不可怕,可怕的是环境遭到破坏。草地不再是绿的,天空不再是蓝的……世界末日并不可怕,可怕的是人类将自己毁灭自己!保护环境,保护我们共同的家园吧!
为了让草地更绿,为了让河水更清,为了让天空更蓝,让我们一起来保护环境。保护环境,从我做起。现在还不晚,为了你我他的幸福生活,保护环境,刻不容缓!

森林里,树木成群,百花盛开。啄木鸟像往常一样,停在一棵树上东啄啄,西啄啄,在给大树治病。
突然,它看见一位不速之客——一位伐木工人,正拿着一把柴刀在砍树,一边还悠闲地抽着烟。“啪嗒”一声,烟头还没熄灭就被他无情地摔到了地上。难道他不知道,没熄灭的烟头会引起火灾吗?看着他目不转睛,两眼放光的样子,一定看见了许多钞票朝他飞来了吧!啄木鸟气愤的暗想道,顿时升起了一股无名之火!啄木鸟飞快地飞到那个伐木工人的背上,用尖尖的嘴巴啄他的脑袋。一边啄,一边暗想:看来槐树爷爷的话真没有错,人类的脑子里真的有“贪婪虫”!要不然,干嘛砍树呢?干嘛破坏资源,干嘛破坏环境呢?干脆,做做善事,给这段木头治治病吧!那位伐木工人突遭啄木鸟袭击,一时没反应过来,愣了一下便飞快地扔下柴刀捂着脑袋就跑了!
透过这幅漫画,透露出了人的无穷无尽的贪婪和欲望。借着这幅漫画讽刺了人类,告诫人们要珍惜资源,保护环境!是的!雨果曾经说过,让风沙不再猖狂,换地球一片绿色铺垫!人类破坏了自然环境,也受到了应有的惩罚,沙尘暴,泥石流,干旱,洪水泛滥等数不清的自然灾难接踵而来。造成了无数人的牺牲,是人类应受的。
带着欢乐舞步,让风沙停止,让小鸟起舞,让绿色腾飞吧!
