As time goes by,the importance of constructing a green campus is gradually executed in current society,not only for that the campus is the place which aimed at developing talents,but also for the campus is a symbol to a city.

The green campus not only refer to green environment,but also refer to a new idea about the ways of educating and managing the students,mainly letting them accept the knowledge and build up the

spirit of loving nature and being responsible for the environment,also,letting them take an active part in the actions of protecting the environment and keep the idea of sustainable development in mind.

In order to construct the green campus,we should do from two aspects.First of all,we should make every effort to study hard,aimed at becoming the knowledgeable ones with high qualities as well.Secondly,we should make ourselves more comprehensive,doing from the team-work spirit,the environmental consciousness and so on.Besides,we should be concerned about society,our motherland and the whole world,as well as learning to innovate and actively practice.

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。

[保护环境的英语小作文

一天，我在街道的拐角处发现了两枚电池。我想：是谁乱丢电池？于是我把它捡了起来。

记得科学老师给我们说过，一节一号电池烂在地里，可以使1平方米的土壤永久失去利用价值；一粒纽扣电池可使600吨水受到污染，相当于一个人一生的饮水量。若将废旧电池混入生活垃圾一起填埋，或者随手丢弃，渗出的汞及其他重金属物质就会渗透于土壤，污染地下水，破坏人类的生存环境，威胁到人类的健康。

但废电池的危害不是马上能看到的，就好像吸烟一样，时间长了才能体会到它的害处。平时不是有人说“乱扔电池危害不大”吗？我觉得这句话既不对又不负责任。电池中的有害物质所造成的疾病和对环境的污染是无法想象的，废旧电池里的铅、汞等有毒物质通过各种途径进入人的体内，长期积蓄难以排除，损害神经系统、造血功能和骨骼，甚至可以致癌，这并不是危言耸听啊！

现在，不少城市都设立了废旧电池回收箱，我想我们也应该这样做，再也不能让废旧电池无家可归了。据说，废旧电池还能进行再利用呢！集中收集，废旧利用，既节能又环保，一举两得，何乐而不为呢？

In the past two years, my parents took me to travel to many places,

including big cities, small towns, famous mountians and so on. Therefore, I like

traveling and I hope I can visit to many more places. Since then, I hope I can

be a tour guide in the future, so I can travel to many tourist attractions.

Besides, I can meet various people and I think communicating with different

people is interesting, wchich can broaden my field of vision. I hope they can

share their life stories with me so that I can know the general life of a place.

I know it would be a challenging job, but I believe I can do well in my job.

在21世纪的今天，人类的科学经济发展已经达到了很高的水平。然而我想问：你们有没有意识到人类的活动对环境会造成怎样的影响呢？

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失，使许多地区成为沙漠。人类的活动范围在不断减少，这不可怕吗？

人类除了破坏森林之外，难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性，目前世界上60%的地区面临供水不足，已有20%的人口难以得到清洁水，51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的，现在的工厂及我们生活中的污水，没有通过处理就排出去。这不是最好的证明吗?据研究，每排放1立方米污水，就污染14立方米天然水。想一想，这是多么可怕的数字？

在工厂排出的浓烟里，我们不知道浓烟是污染大气的吗?科学家发现，至少有100种大气污染物对环境产生极大危害，直接影响人们的健康。

难道我们想在这种环境中生活吗？当然不想；那让我们用行动来证明吧！我们可以从我做起，从现在做起，从身边做起。树立爱自然、爱护环境的意识吧！来做宣传环保的使者!让我们一起为保护环境行动起来吧。

When we are very small, we dream to be the great person in the future, such

as the scientist, the policeman and so on. It is good for the children to own

the big dream, so that they will study hard and fight for their future. But the

fact is that not all the person can become the great person, most people are

doing the ordinary jobs. In my opinion, ordinary is beautiful, too. Though they

are not doing the fine jobs, they find their own place and make a contribution

to the world. Take the cleaner for example. They wake up early and do the

cleaning work. People dare not to do the job because it is so dirty, but the

cleaners decorate the city with their hard work. The cleaners are the ordinary

people while doing the great job.

家园，是我们赖以生存的地方。我希望它是干净、没有污染的，而且温馨又舒适。

亲爱的朋友，你可知道保护我们的家园有多么重要吗?我们的家园是由许许多多的东西组成的，它们都扮演着重要的角色。天上的太阳，是不可替代的，它给我们带来了温暖，地上的一切生物都离不开阳光。森林对我们来说也是不可或缺的，它可以释放出许许多多的氧气，供给人们呼吸。水呢，那就更重要了，一切动植物的生存都离不开水。因此，阳光、空气、水对我们来说都是必不可少的。所以，我们要好好地保护这些不可或缺的东西，保护它们也就是保护我们的家园。

大自然是美妙的，也是五彩缤纷的。它需要我们去保护它，呵护它。保护我们生存的环境：让我们珍惜每一张纸，因为那是珍惜森林和河流;让我们家家都用节能灯，支持绿色照明;不随意乱扔瓜皮果壳、不随地吐痰、不乱扔乱倒垃圾、不攀折花草树木、不践踏公共草坪;节约用水用电，不乱排污水，绿化美化环境，积极参加环保公益活动。节约资源、减少污染，在实践中领悟环保意义，提高环保意识，需要我们每一个人都行动起来。

现在，有很多人都特地买了几个能重复使用而且质量坚固的环保布袋，到超市买东西时就拿出来用，可方便啦!同时，也有的人翻出了她们的菜篮子，去买菜时也很少看见那些花花绿绿的袋子了。她们直接把菜装在篮子里，方便极了!可见，现在的人们对环保都有了新的认识。所以说：“保护环境，人人有责。”这句话我们要铭记在心!

让我们共同携起手来，保护环境，保护自然，创建绿色校园，共建美好家园吧!

友谊是一条善良的河流,澄清着沿路的风尘;是上天在人的心灵中植下的一方净土,培育着诚实善良的花朵。下面是小编整理的关于友谊的英语作文，希望对大家有帮助。 关于友谊的英语作文一：

Friendship is a kind of human relations. It is a human instinct to make friends.When in trouble, we

need friends to offer us help, support and encouragement. With success achieved, we also need friends to share our joys.

Friendship is also one of the greatest pleasures that we can enjoy. It implies loyalty, cordiality, sympathy, affection,and readiness to help. No man can make the most of his life without carefully and conscientiously striving to win the right kind of friends as he goes along.

Knowing how valuable friendship is, we should be very careful in making friends. Real friends are those who have good character, superior ability and kindness of heart. Real friends can share all our sorrows and double all our joys.While making friends, we should take care to select those who have such fine qualities. Then we should treat our friends with courtesy, be careful not to interfere unreasonably with them,and not to ridicule their proceedings. We should forgive their failures and do our best to help them. In short, when we have established friendship, we ought to cherish and treasure it by means of words and deeds. Only thus, can we develop real friendship and keep the sacred lamp of friendship burning all our life. 关于友谊的英语作文二：

making friends is a skill like many other skills. it improves with practice. if you want to meet people and make friends, you must be willing to take some actions. you must first go where there are people. you won’t make friends staying home alone. join a club or a group. taking with those who like the same things as you do is much easier. or join someone in some activities. many people are nervous when talking to new people. after all meeting strangers means facing the unknown. and it’s human nature to feel a bit uncomfortable about the unknown. most of our fears about dealing with new people come from doubts about ourselves. we imagine other people are judging us of finding us too tall or to short, too this or too that. but don’t forget that they must be feeling the same way. try to accept yourself as you are and try to put the other person at ease. you’ll both feel more comfortable.

try to be self-comfident even if you don’t feel that way. when you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile.

if you see someone you like to speak to, say something . don’t wait for the other person to start a conversation.

just meeting someone new does not mean that you will make friends with that person-friendship is based on mutual liking and “give and take”. it takes time and effort to develop. 关于友谊的英语作文三：

Friendship Friends play an important part in our lives,and although we may take friendship for granted,we often dont clearly understand how we make friends.While we get on well with a number of people,we are usually friends with only a very few----for example,the average among students is about 6 per person.In all the cases of friendly relationships,two people like one another and enjoy being together.but beyond that,the degree of intimacy between them and the reasons for the shared interests vary enormously.As we get to know people we take into account things like age,race ,economic conditions,social position,and intelligence.Although these factors are not of prime importance,it is more difficult to get on with people when there is a marked difference in age and background.

Some friendly relationships can be kept on argument and discussion,but it is usual for close friends to have similar ideas and beliefs,to have attitudes and interests in commen ---they often talk about being on the same wavelength .it generally takes time to reach this point.And the more intimately involved people become,the more they rely on one another .people want to do friends favours and hate to break a promise.Equally,friends have to learn to put up with annoying habits and try to tolerate differencesof opinion.wWw.xiNgkoo.coMIn contrast with marriage ,there are no friendship ceremonies to strengthen the association between two persons.But the supporting and understanding of each other that results from shared experiences and emotions does seem to a powerful bond ,which can overcome differences in background ,and break down barriers of age, class or race. 关于友谊的英语作文四：

Friendship is priceless, is not buy friendship, and when you give up your friendship who, you need his help, he can not help you, even if you can not buy with thousands of gold back.

[关于友谊的高中英语作文

星期天，我去姥姥的老家玩。走在路上，一望无边的田里，农民正忙碌着收割庄稼。突然，一阵阵黑烟飘来，呛的我直咳嗽。我一边跑一边问：“这是哪儿来的烟？呛的我快受不了啦！”旁边的人也直抱怨：“是呀，这几天焚烧麦杆，我们坐在附近的也倒霉了！”另外一个人也连忙接话：“是呀，这样下去世界会变成啥样子呀！”看着滚滚浓烟，我仿佛看到了许多年以后的情景：

早晨刚开门，一阵黑烟直扑进来，人们不得不戴上厚厚的口罩。回家一进门就要赶紧把门窗关紧，否则全家人就得不停在咳嗽。尽管室内空气混沌，人们却不能打开窗户透透气，也不敢出门游玩。从窗户望出去，浓烟滚滚，空气再也不清新了。花草树木有的熏死了，活着的也一个个耷拉着脑袋。公园里最漂亮的景点也折腾的不成样子了，儿童乐园、麦香村等商店有时一个人也没来，最后只好倒闭。人们在家里没事做，快闷死了，小孩更是哭着闹着，大人也无可奈何地唉声叹气。

我想着想着，不禁大叫：“人们，不要再污染环境了，这样下去我们怎么受得了啊！”一旁的农民说：“你说的倒好，草杆不焚烧怎么行？”我愤愤不平道：“谁能发明一个自动焚烧器多好呀，焚烧的又好又不污染环境，照这样下去，世界真变得不知成啥样子了！”农民嘲讽道：“你来发明呀，你发明出来，我把全部家当送给你！”“我一定能发明的出来！”“你试试呀！”我大声叫道：“我长大了一定要发明一个！”

说完，我转身和家人一起上了长途汽车，车开远了，农民们还在后面嘲笑：“输了吧……”

How to protect the environment has become one of the biggest problems in the world .

It’s our duty to protect our environment . No matter where we live , we should do something to keep our neighborhood clean and tidy . We can collect waste paper or other waste things for recycling. We should plant more trees and we should prevent those factories from pouring waste water into rivers, lakes and fields. We shouldn’t leave rubbish everywhere and spit in public places . We mustn’t pick the flowers or step on the grass in public. If everyone tries his best to protect the environment , the world will become much more beautiful and our life will be better and better .

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？”

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

导读：你是想在一个干净舒适的校园内学习呢，还是在一个乌烟瘴气的校园内学习呢，保护校园环境就是在保护着我们自身的利益，不要事不关己高高挂起。下面小编为大家带来关于英语作文保护学校环境的范文，希望能帮助到大家。

保护学校环境（二）

The protection of the border is not a new problem for us, and our government has long proposed clear targets for governance. As every ordinary person in real life, although it is impossible to work directly in environmental protection, we can start from small things and start from me. Can you raise your hand when you see the tap in the bathroom? When the battery runs out, can you classify it instead of throwing it away? How about when shopping doesnt use ultra-thin plastic bags? ...... Small things are small, but they reflect how much environmental awareness we have.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 tree. 20 waste recycling boxes can create a beautiful pen container. Recycling one glass bottle to save the energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

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。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。

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!

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。

如今的地球姑娘已经是头发稀疏，脸儿黄黄，衣服脏脏。树木大片砍伐，江和污染，这一切实在太严重了！所以，我为地球姑娘想了一个装扮她的好方案，使她能在宇宙千年选美大赛中获得冠军。

方法一：增加头发。把树苗栽进地球姑娘的头上，每年都要加以保护，春天、夏天喷撒防虫剂，不能让可恶的虫子破坏树苗，更不能让人们滥砍滥伐。这样十几年后，小树苗长成绿绿的大树，地球姑娘的头发又长起来了。

方法二：改变地球姑娘肤色。多种植绿草，把大片沙漠变成绿洲，这样沙尘暴军队就不会出现了，地球姑娘黄黄的脸蛋又变得好看。

方法三：穿漂亮衣服。赶快把脏脏的衣服脱下，穿上漂亮衣服。怎样换呢？看那城市乡镇，高高耸立在烟囱每天喷放着“灰色病毒”，大小工厂的排污管，每时都排放着污水。这是地球姑娘受到损害的主要原因，要彻底根除这些污染，让天空变蓝，河水变清。鸟儿尽情地歌唱，鱼儿自在地游泳。地球姑娘穿上最美丽的衣裳。根据我的这些方案，地球姑娘在宇宙千年选美大赛中准能获得冠军环境污染治理作文作文。

Today the quality of our natural environment has become an

important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the

importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.

Sichuan is located in the Upper Yangtze Valley in the southwestern part of the country. The second largest of the Chinese provinces, it covers an area of 220,100 square miles (570,000 square kilometres). Szechwan is bordered by the provinces of Kansu and Shensi to the north, Hupeh and Hunan to the east, and Kweichow and Yunnan to the south and by the Tibet Autonomous Region to the west and the province of Tsinghai to the northwest. It is the most populous province in China. The name Szechwan means “Four Streams” and refers to the four main tributaries of the Yangtze River, which flows through the province. The capital, Cheng-tu, is located in the centre of the province.

From economic, political, geographical, and historical points of view, the heart and nerve centre of Szechwan is in the eastern basin area, commonly known as the Sichuan, or Red, Basin. Its mild and humid climate, fertile soil, and abundant mineral and forestry resources make it one of the most prosperous and economically self-sufficient regions of China. The area has been seen by some as China in a microcosm and is often viewed as a country within a country. The Chinese call the basin Tien Fu Chih Kuo, which literally means “Heaven on Earth”.

尊敬的校领导：

你们好！

我是我校六年级一班的一名学生，在这个新建的校园里我一经生活了整整一年了，在这一年里我已经对这个新的学习环境建立了深厚的友谊。一天在这个美丽的校园里待8个小时的我已对它的每一个角落都十分了解。

我们的校园如同一个美丽的大花园，那里有白花盛开的圆形花潭，在笔直的硬化路傍边种着绿油油的草坪。平如水面的操场令人向往，象堡垒一样的室内体育馆，富有弹性的木地板让人们走进里面就充满运动感。为我们在恶劣环境下可以继续体育锻炼。

同学们都在楼上上课，在课间同学们就在楼道里玩耍、聊聊天等等。一天我在从楼下经过时，看见空中好象有什么东西掉下来，认真一看原来是楼上的同学吃完的小吃的食品袋，后来这样的事情不断的发生，有时还会有什么水果皮从空中落下来，有时还会落到别人的头上，这样不文明的事情为什么会发生哪？

在与同学的日常生活中，有些同学对从楼上往下扔塑料袋、瓜果等不文明现象作出了回答，他们说，从2楼就没有了垃圾桶，而且在十分钟的时间里又不想到楼下扔垃圾所以就在楼上的走廊里扔掉了。而且老是掉到行人的生上。

这里平时就有风，而且风中还夹杂着一些包装袋，令人马上想要离开这里，是什么原因导致平如镜的操场变成了这样那？

在咨询同学中得知操场上和操场旁边没有垃圾桶，所以同学们就在吃完东西后的包装袋就随手扔掉了，就造成了现在的风一起，垃圾满天飞。

以上众多不文明的现象，所以我建议：

1。在学校的其他楼层上也多设几个垃圾桶，或是多建几个垃圾点也行。

2。操场上的环境问题是操场旁边的道路上没有垃圾桶，所以人们才水手乱扔垃圾，建议在旁边多设几个拉几桶。

3。先在社会都在教育人们要文明，我们也可以以此为题，展开一才文明大比拼活动，倡导同学门争做一个文明的学生。

希望校领导能采纳我的意见，使我门的校园变的更加干净、更加美丽。

Protecting the Environment

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends?

Chinese New Years day, we at home the next day to discuss where to go. Because these days the weather is clear, sunny, cloudless, and we unanimously decided to go to picnic in the mountains. So, we have informed Yidie Aunt them, ready to picnic the next day when the dumpling skin, meat, condiments and bowls, chopsticks, pots and so on. The next day, we are mighty walked to the hill.

After a lengthy one hour, we finally boarded the summit. Then, we started the division of labor: Yidie had to base lesions, aunts dumplings, some of our kids went to the collection of firewood. A moment later, a good stove base, and great people to immediately lift the pan up, doped Sheung Shui. This is, Chai has Picking is running out, we started to light a fire. Fire is getting bigger wang, the boil was the dark. 3 Yidie saw, and said humorously: "with a small double (my nickname) is the same as black." Listening to other people, have a laugh. Moment, dumplings have been wrapped, and five aunt carrying his dumplings to the pot was about to fall, the three Yidie looking dumplings, and shook his head and said: "The package was too fat, and nothing like the small pairs only skinny monkey." Once again, other people laugh, I laugh again and good gas, not help then added: "with the same glowing three-Yi Die." Other people laugh even more fiercely.

I do not know how long before, dumplings cooked in. We are holding a bowl of Wai in the pot next to desperately grab dumplings. I finally grabbed one, is to eat, they were snatched his brother.

After eating dumplings, we discovered that the sky late and had to leave here, reluctantly go to the house to the direction.
