关于保护水的英语作文初一(经典20篇)

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.

With the development of science and technology, peoples living standards are getting higher and higher, environmental problems are more and more serious, you found it?

Lets talk about water pollution! Gas stations and other factories always put the water without purification to the river, resulting in small fish without home. 50% of our country can not use clean water, this figure is not terrible? So saving water is imminent, you still waste it?

Lets talk about the problem of reducing trees! Now a lot of trees have been cut down by us, so the dust storm came, the flood came, nature to revenge us. We all know that the use of disposable chopsticks are made of trees, if each of us every day can use a pair of disposable chopsticks, one year down can keep ten thousand trees, see this time, you are still presumptuous Behavior?

Lets take a look at the sky, the blue sky is gone, the white clouds are hidden, is it really gone? No, they are just "smoke" by the smoke from the factory.

These are water caused by it? Are our own human beings, if not felling of trees, garbage, a reasonable discharge of purified sewage, I believe our planet will be beautiful. Protect everyone from the earth, let us work together to protect the environment!

随着科技的发展，人们的生活水平也越来越高，环境问题也越来越严重了，你们发现了吗?

咱们就来说说水被污染的问题吧!加油站和其他工厂总是把未经过净化处理的水排放到河里，导致小鱼没有了家。我们国家有百分之五十一的人都无法用到干净的水，这样的数字难道不可怕吗?所以节约用水已是迫在眉睫，你还在浪费吗?

我们再来说说树木减少的问题吧!现在好多树木已经被我们砍伐叻，所以沙尘暴来了，洪水来了，大自然来报复我们了。我们都知道使用的一次性筷子都是用树木做的，如果我们每个人每天可以少用一双一次性筷子，一年下来就可以保留千万棵树木，看到这时，你还在放肆自己的行为吗?

我们再来看看那天空，蓝蓝的天不见了，白白的云也藏起来了，是真的没有了吗?不是的，它们只是被工厂排放的浓烟给“保护”起来了。

这些都是水造成的呢?都是我们人类自己，如果不乱砍伐树木、垃圾，合理排放净化过的污水，相信我们的地球就会很美。保护地球人人有责，让我们一起来保护环境吧!

以前的西塘，景色优美，风光宜人，塘水清澈见底，小鱼儿在水中漫步，野鸭们和各种不知名的小精灵在水上戏耍，塘边垂柳婀娜多姿，花儿争奇斗艳……可后来西塘却变了。

西塘变成了“垃圾场”。塘面上漂着许多垃圾袋，有时还漂着臭南瓜。水面下全都是黑黑的泥和人们丢的果皮。怎样才能让西塘不受污染呢?

从现在开始，我们要清理塘底的污泥，不让塘水流进西塘里，我们要塘边放一些垃圾桶，还要立一些告示牌，告诉塘边商店的老板和过往的行人不要乱丢垃圾了。

让我们行动起来，加入保护西塘的环境的行列中去吧!我相信不久的将来，西塘一定能像以前那样美的。

As human beings, we communicate throughout our lives for various porpoises.

But just because weve been communicating for a long time does not mean that we

are always successful or that we can’t improve our communication skills. How can

we convey successful communication? Well, there are several useful tips may help

you to improve your communication skills.

First of all, listen and respond thoughtfully to others. You should spend

more time listening to others instead of boasting yourself. Some of us are very

egocentric, which means self-focused. If you spend too much time talking about

your own stuff, the people around you may think you are a tedious and annoying

person. So, the best way to do is to consider our friends’ thoughts and

feelings. Try to be a good listener, when you express yourself, thinks about it

carefully before you really say it.

Second, appropriately adapt messages to others. It is not enough to be

sensitive and accurately understand others; when your send out your message, you

pick up the best ways and respond to others to achieve your communication goals.

But it does not mean to say something that the listener wants to hear. That

would be unethical. Appropriately adapt messages to others means carefully

editing and shaping your responses so that your messages can be understood by

others and you can achieve your goals.

Last but not least, try to interpret nonverbal messages. As we all know,

unspoken messages can express powerful ideas or emotions with greater impact

than mere words. You should try to observe others facial expressions or

movements and give correct responds to others. You can see the emotions or

attitude from one’s gesture stops. Be sensitive and appropriate interpreting

others.

Most people learn communication rules from experience, by observing and

interacting with others. You can do that too, if you have enough patient and

determinations.

两湖一库无非就是指百花湖、红枫湖、阿哈水库。这两湖一库可是我们的生命之水，是贵阳人民的摇篮，但是现在这两湖一库正在受到严重污染。有很多不自觉的人往河里扔垃圾，在河里方便、钓鱼……不光这样，许多工厂、企业不断的在排放污水，严重的污染了水质，使得生态环境被破坏，鱼虾绝迹。

我们贵阳人的生命之水被污染了，说不定在不久的将来，贵阳人民全部都会得疾病死亡，造成的原因就是我们喝的水被污染了。难道我们要让这臭哄哄的河水流入大海、流入长江、黄河吗？难道我们一定要在史书上添上贵阳，是世界上第五大沙漠吗？

还好现在已经有一部分人觉醒了，懂得了环保的重要性。但是还有一部分人，还在随便扔垃圾。

所以为进一步净化“两湖一库”水质，贵阳市将陆续向红枫湖、百花湖、阿哈水库各投放600万、400万和200万尾鲢鳙鱼苗，加上此前“两湖一库”已经另行投放了1000万尾鱼苗和50吨鱼种，今年贵阳市累计向“两湖一库”投放近4000万尾鱼苗鱼种。

我现在作为一名贵阳市民，也作为一名优秀少先队员，我一定要做到保护两湖一库，珍爱生命之水。

We grew up in a happy times, living conditions have made a lot of improvement than before. But the environment around us has suffered severe damage, human homes, earth is facing ecological crisis, if not protect the environment, human will be faced with a major disaster.

In recently listen to TV news said: our capital Beijing area and more dust storms have taken place in the city, these economic developed city almost was huge sand "bury", the oasis is gradually reduced, we human beings that only themselves to blame disorderly cut down trees, destroy the environment, make the soil and water loss. Dont, only the forest into the barren hills, grassland into desert, humans will suddenly realize?

Now the most polluted on earth resources, is the water. River that the original clear float above is full of garbage, plus factory emissions of industrial wastewater, the water is now dark and smelly, passing from the river to wu wear the nose, the fish in the river ah, shrimp had long ago lost.

Just take a look at the sky, is always a grey, which is called the blue sky white clouds, it is grey day ash cloud. Can only look at the moon at night, the stars are gone. See the most is the factory, thick tall a black smoke from the chimney. Took to the streets, often can smell exhaust frying. Recipients pollution everywhere around us.

Environmental consciousness is the people should have modern consciousness of the 21st century, in order to in the new century to create a beautiful and pleasant environment, let us take action immediately: save a drop of water, save electricity, once more take a tree... To protect our home together!

我们生长在一个幸福时代，生活条件比以前有了很大的改善。但是我们周围的环境却遭到严重破坏，人类的家园——地球正面临生态危机，如果不保护环境，人类将面临着重大的灾难。

在前不久听电视新闻说：我们首都北京和区多城市都发生了沙尘暴，这些经济发达的城市几乎被巨大的风沙“埋没”，绿洲正在逐渐减少，这只能怪我们人类自己乱砍树木，破坏环境，使水土流失。难道，只有等森林变成了荒山，草原变成了沙漠，人类才会恍然大悟吗?

现在地球上受污染最严重的资源，就是水资源。原来那清澈的小河，现在上面飘满了垃圾，再加上工厂排放的工业污水，河水现在又黑又臭，从河边路过的人都要捂着鼻子，小河里的鱼呀、虾呀早就消失得无影无踪了。

再抬头看一看天空，总是灰蒙蒙的，哪叫蓝天白云，简直是灰天灰云。晚上也只能看看月亮，星星都不见了。看得最多的还是工厂那又粗又高的烟囱里冒出的一股黑烟。走到街上，经常可以闻到汽车排出的油烟味。我们周围到处都受者污染。

人类是地球的主人，但也是它的破坏者，又是最终的受害者。作为新世纪的主人，我们不能再让环境继续被污染下去了。环保意识是21世纪人们应有的现代意识，为了在新世纪里创造一个优美宜人的环境，让我们立刻行动起来：节约一滴水，节约一度电，多载一棵树……共同保护我们的家园吧!

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

东江源头的保护状况对于整个东江流域有着独一无二的环境和社会意义，达能中国饮料2015年初携手寻乌县政府、世界自然保护联盟(IUCN)共同启动了“魅力寻乌”水生态保护项目，通过重点推进寻乌东江源生态系统的保护和恢复、促进农村社区可持续发展以及推动公众环境教育，实现源头区域生态保护和社会发展的共同进步。

《小楼重生记》记录的是“魅力寻乌”项目中，一群来自华南理工大学建筑系的学生利用自己的所学所长投身公益——对东江源村的一栋客家老宅进行精心改造，将其打造为“魅力寻乌”项目的环境教育基地。

小楼为当地的水生态保护提供了宣教场所，同时也为当地村民和学生提供了公共活动空间。

青设计团队的成员说道：“理想的建筑不应该是人和自然的隔断，相反它应该融入自然，让人始终和山水草木保持亲近。我们希望水生态保护的意识和知识将从这栋房子开始，慢慢普及开去，这对整个寻乌水生态保护项目，对保护东江水这一使命来说，都是关键的一步。”

在水一方有伊人

《在水一方有伊人》的主人公张艳是IUCN龙门项目负责人，近两年来一直在这个位于广东省惠州市的小县从事小流域保护工作。广东省惠州市龙门县，是达能益力矿泉水的优质水源地。从2008年开始，达能对龙门水源地展开多年水源、土壤和环境研究，建立起三级水源保护区及缓冲区，对水源地进行着全方位保护。

2014年，达能携手世界自然保护联盟等发起“生态龙门，活力东江——嘉泉水源地可持续保护”项目，推动社区体系建设、生态恢复和替代生计，通过可持续的方法，达到促进当地社区经济、恢复生态与保护天然水源的和谐发展。

做贸易出身的张艳初次来到龙门的时候便喜欢上了龙门的新鲜空气，在得知“生态龙门”项目后，张艳便选择作为项目组的一员留在了龙门。影片《在水一方有伊人》记录了张艳在日常工作中如何推动“生态龙门”项目在当地实施，包括建立村民互助小组，邀请专家为村民讲解生态种植技术，共同商讨替代生计方案，开展立体果园、蜜源恢复等生态种植的试点等。通过“生态龙门”项目，当地可持续生计与可持续流域管理并肩发展，从而为两千万当地与下游居民带来更多福祉。

“我们的衣食住行都离不开水。”对于未来的希冀，张艳说道，在那里她觉得自己更像是自然生态圈中的一份子。“希望‘龙门模式’可以扩展到东江乃至整个珠江流域，并为国内外其他大型流域的管理提供参考。有好水就有未来，没有好水谈何未来。”

与您携手，恢复理想水生态

达能坚信，健康的食物来自健康的自然。水是达能水事业部的业务基石，与水的密切关系使我们懂得：水资源一旦被污染就很难恢复，因此可持续地利用水资源是我们最为重要的责任之一。2014年，达能水事业部发布“好水好未来可持续发展战略规划”，从水生态、水利用、水供给、可持续包装和碳足迹五方面全面实践可持续发展理念。

在中国，达能中国饮料对产品水源的可持续开发和对水源地的保护，倾注了大量心血，结合企业运营与中国实际，构建“达能中国饮料水生态保护战略”。

从张艳到青设计，从龙门到寻乌，达能中国饮料在东江流域实践两个在地的水生态保护项目，秉承“达能中国饮料水生态保护战略”，从不同的侧重点尝试及探讨水生态保护的创新技术方法、公众参与模式和政策支持机制。计划2016～2020年，达能中国饮料将构建东江水基金，倡导流域尺度水生态保护。

未来，达能中国饮料诚挚期待与您携手，一起寻找更好的可持续发展的方式来利用水资源和恢复理想水生态。

Hello!I am a girl,My name is Zheng jingyi,I’m 12 years old,I come from Zhangzhou,I’m in Class 2,Grade 7.My telephone number is 123456789.I have long hair,big eyes,small nose and small mouth.Look!Who is she?She is my good friend,her name is Chen han,she is 12,too.She is from Zhangzhou,too.She is 14 years old,she is in Class 3,Grade 7,She telephone number is 987654321.She has short hair,big eyes,small nose and wide mouth.We are in the same school,but in different Classes.

When it comes to the environment, most people believe that now is in the shake head to sigh: water pollution, dust storm raids, white garbage everywhere... However, more and more people just sigh, but no action. Only when the sky is no longer clear our heads, remembered that should protect our environment? When we were at the foot of the land into desert, just regret not cherish the nature? I want to say, no, we can all start from to protect our school environment, from the small start bit by bit.

Go to school that day, I and several classmates said and laughed to sit into the corridor, see at a distance a cordial and familiar figure, when we miss zhao. Suddenly, she paused, with his head down as if found any. All of a sudden, she crouched down... Strange, she do? Is to tie his shoes? Or a sprained foot? We havent stepped forward, but she from his pocket a piece of facial tissue, hand a pinch, picked a piece of chewing gum on the ground up, wrapped up, and then threw it into the dustbin. She turned around and saw us strange eyes, smiled and said: "not surprisingly, dont say the whole school, even if lets class, if a person a piece of gum, we will be glued here. If everyone take good care of our environment, we can live in comfort."

Miss zhao said good, do better. I think I did pretty good also. For example, our class classroom environment, there are flower, grass, helped my contribution! Since as health group leader, I work hard, meticulous work. If I was in this respect "xiao-he only expenses furore," then I class "plant corner" career for me, but made great contributions

Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease.

This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of years. We grow old by deserting our ideals.

Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.

Whether 60 or 16, there is in every human being’s heart the lure of wonders, the unfailing appetite for what’s next and the joy of the game of living.

In the center of your heart and my heart, there is a wireless station; so long as it receives messages of beauty, hope, courage and power from man and from the infinite, so long as you are young.

When your aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you’ve grown old, even at 20; but as long as your aerials are up, to catch waves of optimism, there’s hope you may die young at 80.

早晨，我背着书包走进校园。

Morning, I entered the school with a bag.

路两旁的花坛里，苍翠的青松，墨绿的冬青，在寒风中左右摇摆。

Road on both sides of the border, the green pine, green holly, in the cold wind sway.

这时，一位叔叔正要把抽完的烟蒂扔向花坛，我急忙赶过去说："叔叔，请爱护环境，不要随地乱扔烟蒂。"

At this time, an uncle was about to finish the cigarette butts into flower beds, I hurried over to say: "uncle, please take good care of the environment, do not throw cigarette butts. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔看着我不好意思地笑了，说："对不起，小朋友。"说完，他主动把烟蒂掐灭，送到垃圾箱里。

Uncle looked at me and smiled sheepishly and said: "Im sorry, kids. "Finished, he took the initiative to put out cigarette butts, sent to the dustbin.

我高兴地说："谢谢你，叔叔。"

I am happy to say: "thank you, uncle. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔也笑着夸我："你真是一个爱护环境的小卫士。"

Uncle smiled and said I: "you really are a guardian to protect the environment. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

地球上的水资源，从广义来说是指水圈内水量的总体。包括经人类控制并直接可供灌溉、发电、给水、航运、养殖等用途的地表水和地下水，以及江河、湖泊、井、泉、潮汐、港湾和养殖水域等。水资源是发展国民经济不可缺少的重要自然资源。在世界许多地方，对水的需求已经超过水资源所能负荷的程度，同时有许多地区也濒临水资源利用之不平衡。

我们中国是世界上十三个缺水国家之一，有许多地区严重缺水，可是，如今人们对水资源却还不够重视，浪费水的现象非常多，例如：洗完手后不关紧水龙头、乱用水、玩水枪这样没有意义的游戏，并且还浪费水、用许多许多的水去洗东西，洗干净了还玩水……如果全国人都这样浪费，那这些水可以用来做许多事情，或许可以拯救一个干旱地区！

缺水，不仅对人类有着威胁，对大自然界也有着紧密的关系，植物，如果没有了水，那就很难生长，吸收不了水分，那么生长不了多久，就会枯竭。动物，更是与人类相同，动物也要吃东西，也要喝水，如果没有了水，动物也很可能渴死。如果植物稀少，那氧气就不会多，人类还会面临着呼吸问题，而且空气的清新度也会减弱，那人类就会呼吸着乌烟瘴气，如果这样，人类就会体弱多病，如果体弱多病，就需要许多药物品，而许多珍贵的药物品，又都是植物，或者动物……

所以，请不要想到，缺水只是会渴罢了，如果不重视这个问题，继续浪费水下去，那么，不仅是我们中国的问题了，要面临的，是全世界的环境与生存的问题！！

shark-skin like swimsuit

A new high-performance swimsuit,developed by mimicking the skin of sharks,will be worn by top athletes in Athens from this week.

The revolutionary new fabric,developed by Speedo,is the result of four years of research and development that began with the study of shark skin at the Natural History Museum .

The new swimsuit,called Fastskin FSII,increases a swimmers speed by reducing passive drag through water by up to 4% more than the next best swimsuit.

Research into shark skin texture and movement through water was carried out under the guidance of Natural History Museum fish expert Ollie Crimmen.

Tiny teeth cover the surface of a sharks skin and the shape and positioning of these teeth vary across the body to manage the flow of water.

With these findings Speedo created a full bodyskin with different fabrics on different parts of the body and for the first time,male- and female-specific and stroke-specific swimsuits.

一天下午，我和妈妈还有楼上的奶奶去北山的樱桃沟玩。我们边走边说，一边欣赏着路上的美景。

走着走着，我对妈妈说：妈妈，妈妈，我想上厕所。妈妈说：别急，前面就有公厕了。果然，不一会儿，就看见路边有一座屋顶是三角形的漂亮的小房子，上面有金色的公厕两个字。我蹦蹦跳地走进干净的洗手间，上完厕所出来时，看见洗手处的水龙头水哗哗直流。我想：可能是有人忘记关水龙头了，我赶快走过去关上水龙头。

走出来看到妈妈，我说了刚才事情的经过。妈妈笑着说：好孩子，你做得对！政府把我们生活的环境装扮得这么美，生活条件安排的这么舒适，我们人人都要爱护、珍惜才对！奶奶接着说：是啊，你们从小就要珍惜水。前几天我从电视上看到有的地方天旱没水，庄稼干枯，人们生活极为不方便。人活着没水是不能生存的。我听了，也接着说：妈妈、奶奶，你们说的对，我们老师也是这么说的！

从那以后，我就更注意保护环境了。我常常把洗脸水端去浇花，妈妈洗衣服的水拿去拖地，每次洗手时尽量把水龙头开小些。

我天天告诉自己要珍惜水资源。我还要带动身边的人一起行动起来，节约用水，保护环境！

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.
