尊敬的老师们，亲爱的同学们：
大家好！我想问下大家，我们的生活都离不开哪些呀？有的同学说有空气、有阳光，还有呢？当然还有水了。
水是生命之源，我们的生活离不开水，我们渴了需要喝水，我们洗衣煮饭都需要水，还有我们身边的植物也需要水……有的人说，水，我们家多的是，我每天洗澡的时候都得美美的洗上差不多一个小时，有什么好稀罕的。就是因为我们的无知不懂得珍惜水资源导致现在地球上的饮用水越来越稀缺了。
虽说地球的面积有四分之三都是水，但淡水仅仅占总水量的百分之三，其中三分之二还是冰，可见现在世界上的水资源有多么贫乏！“假如地球上只剩下最后一滴水，那么就是我们的眼泪。”每听到这一句话，我的心就忍不住地紧张起来，真害怕有这么一天。云南XX年遭遇60年一遇的全省性特大旱灾，干旱范围之广、历时之长、损失之大。严重干旱造成全省742万人、459万头大牲畜饮水困难。干旱让庄稼基本颗粒无收，部分家畜无饮水被渴死，孩子们争相喝着脏水解渴，历史就在眼前 。
你知道吗？假如一个水龙头每秒钟只漏一滴水，一年就能积成惊人的三百六十吨；
假如不下雨，地球上的淡水只能够我们用四年左右的时间；
人可以一个星期不吃饭，但不能一个星期不喝水。
所以，水对我们真的非常重要，我们要珍惜水资源，节约水资源。
节约用水，从你我做起。从我们身边做起，下面有几个节约用水的小窍门。比如我们早上洗脸时把水用个小脸盆装起来，洗过脸的水可以拿来洗手冲厕所或洗拖把。开水时把水笼头拧小一点，用完后立刻关掉。淘米的水可以洗菜，洗完后还可以冲厕所。洗完衣服后的水也可以放在桶里洗拖把冲厕所。洗完衣服后，可以把湿衣服晾在阳台上，在下面放一个盆，接来的水可以浇花。我们洗澡时可以把时间缩短些。
如果世界上没有了水，地球就会干裂；如果没有了水，我们人类就可能渴死；如果没有了水，就没有了我们这个美丽的世界。请每个人节约用水，请珍惜水资源，请珍惜大地母亲的每一滴眼泪。
谢谢！

corporate social responsibility ( corporatesocialresponsibility, csr) refers to the enterprises to create profits for shareholders, bear legal responsibility at the same time, also undertake to employees, customers, community and environmental responsibility. corporate social responsibility requires the enterprises to go beyond the profit as the only goal of the traditional philosophy, emphasis on the production process of the value of human attention, emphasis on consumer, environmental, contribution to society.
remember that we have just moved into the building, regardless of the weekend, or at 10: 00 to the company, you will find our this building always lights, as bright as day. i think at that time, the premier for his annual unit gdp energy consumption reduced by 4% goals; and our late night nobody when lighted, why can't we do some contribution for the premier goal?
i think back and forth to oneself, toss and turn restlessly, then president gao ruibin wrote an email, attached the photo, suggested, we should find better energy-saving measures to reduce energy consumption for countries to make our contribution. high total in his busy schedule to see my messages, promptly forwarded to an associated organization and colleagues.
we think, in which after what has changed?
so long, i see every night 9: 00, 10: 00, in our building will be the property of staff to inspect each floor, power off.
to this year july 10th, our office at 7 : 30 after lighting will be automatically closed. see the satisfactory change, i gave a high total wrote an email, attached 2 photos, one is at 11 : 00 then we motorola mansion; it shows our lighting power supply have been almost completely closed, with the last picture really is my not. another photo of our neighbors, a canadian company's mansion; displayed above their lighting like we were building a year ago that way, as clear as daylight ... ...
high total gave me the reply that the name is corporatesocialresponsibility csr, corporate social responsibility, not just the company, as well as each employee 's responsibility. only we work together, we will continue to uphold the company of equality, open, inclusive, innovative spirit, innovation in science and technology continue to forge ahead on the road; our society will be more harmonious.
so what i am going to do, is to nortel ceo write, tell them to the attention of section pass reduction. in the hope that this time next year, in this place, to report my progress.
thank you!
when i was young,i always dreamed that i lived in a beautiful country. there were many flowers and trees around our city.we counld hear the birds singing and see the children dancing. the streets were clear and the the air was very fresh! how nice it was!but that only was a dream of mine!how i wish that it would be come true! so i think we should do something to protect our environment. everyone should make a contribution to protect the environment.
taking care of our environment is very important.wherever you live,you can do something around your neighbourhood.
have you ever thrown any litter onto the ground?have you ever drawn pictures on public walls?have you ever spat in a public place?have you ever cut down trees?if your answers are "no",it means that you have already helped protect our environment.
it is our duty to keep our envionment clean and tidy. you might ask yourself,"have i ever picked up some rubbish and thrown it into a dustbin?have i ever collected waste paper or bottles for recycling?have i ever planted any trees or flowers in or near my neighbourhood?"if your answers are"yes",it means that you have already done something useful to improve the environment.
now i want to say :let`s do our best to make our world more beautiful!
美德演讲稿：节约用水是一种美德
各位老师﹑同学们：大家好！
我演讲的题目是《节约用水是一种美德》。
也许会有很多人问世界上最珍贵的是什么?有人说是石油，有人说是黄金，有人说是生命。我现在告诉大家世界上最珍贵的东西是——水。水是一切的生命之源。
也许会有人说：地球表面最多的是水，大海的水，大河的水，地下的水，谁是取之不尽用之不竭的。请同学们听完这些科学数据就知道水多么珍贵。地球上百分之九十三的水是咸水，不能喝。淡水之占百分之七，而能喝的淡水只占百分之零点八。虽然我国的水资源很丰富，但分布严重不均，南多北少。人均水平很低。有的地方还靠天吃水。
就拿北京来说，它是一座严重缺水的城市。人均水平只占全国人均水平的八分之一，世界水平的三十分之一。节约用水对北京来说是一个非常迫切的问题，而且全世界都面临着严重的挑战!我们作为北京的一员，世界的一份子，还有什么理由不节约水呢?
作为一名小学生，也许我们的力量很小，从一点一滴做起，这样意义却很大。号召家人，朋友，同学们等等。这样人从一个人到几个人，然后就会慢慢波及到全世界的每一个人。这样就会产生无穷的力量。
这是我和我的家人积累的一些节水的小窍门，希望能和大家交流分享。比如把洗菜的水浇花;把洗菜水洗漱用水收集起来冲马桶;把滴水的水龙头关闭;洗澡擦浴液的时候关掉水。节水的方法很多很多，只要我们在生活中从小事做起，从现在做起，节约每一滴水，让我们的地球永远是一个蓝色的美丽的星球!
最后我说一句非常耐人寻味的话：如果我们不珍惜水，世界上最后一滴水，将会是我们的眼泪!!!
谢谢大家!
中学生节约用水演讲稿范文
老师们,同学们,大家好!今天,我演讲的题目是《珍爱生命之水》.同学们,我们知道,人不可缺少水,如果没有了水,动物和人都无法生存.没有了谁就没有了生命,没有了水,地球就是一片死寂.
大家知道,地球上 的面积被水覆盖, 然而却很少有人知道这么大的水量中可被人类利用的淡水总量只占地球上总水量的十万分之三,占淡水总蓄量的0.34%. 目前,世界上已有超过一半的陆地面积,遍及一百多个国家和地区缺水,二十亿人饮水困难.而人类正以每XX年增加 1倍的淡水需求消耗着水资源.到目前为止,人类淡水消费量已占全世界可用淡水的54%. 我国水资源总量为2.8万亿立方米,人均水量不足2400立方米,仅为世界人均水量的1/4,居世界第 110位,我国水资源总量中,可用水储量只有1.1万亿立方米,而目前用水量已达5600亿立方米,城市每年缺水60亿 立方米,全国668个城市中有 400多个供水不足,其中108个严重缺水.因缺水每年造成工业损失2300多亿元.
如果我们不节约用水,后果就会不堪设想.所以相对于不断发展的工农业生产和不断增长得人口,供我们使用的水是非常有限的,所以节约用水势在必行.
同学们,行动起来吧!节水行动就在你我的身边.
你可以在日常生活中随时随地的节约每一滴水.
下面,我给大家提几个节约用水的建议.
一,用淘米水洗菜,再用清水清洗,不仅节约了水,还有效地清除了蔬菜上的残存农药;
二,洗衣水洗拖帕,帚地板,再冲厕所.第二道清洗衣物的洗衣水擦门窗及家具,洗鞋袜等;
三,大,小便后冲洗厕所,尽量不开大水管冲洗,而充分利用使用过的"脏水";
四,夏天给室内外地面洒水降温,尽量不用清水,而用洗衣之后的洗衣水;
五,自行车,家用小轿车清洁时,不用水冲,改用湿布擦,太脏的地方,也宜用洗衣物过后的余水冲洗;
六,家庭浇花,宜用淘米水,茶水,洗衣水等;
七,家庭洗涤手巾,小物件,瓜果等少量用水.宜用盆子盛水而不宜开水龙头放水冲洗;
八,水龙头使用时间长有漏水现象,可用装青霉素的小药瓶的橡胶盖剪一个与原来一样的垫圈放进去,
可以保证滴水不漏;
九,将卫生间里水箱的浮球向下调整2厘米,每次冲洗可节省水近3kg;按家庭每天使用四次算,一年可节药水4380kg.
十,洗菜:一盆一盆地洗,不要开着水龙头冲,一餐饭可节省50kg;
十一,淋浴:如果您关掉龙头擦香皂,洗一次澡可节水60kg;
十二,手洗衣服:如果用洗衣盆洗,清衣服则每次洗,清衣比开着水龙头节省水200kg;
十三,用洗衣机洗衣服:建议您满桶再洗,若分开两次洗,则多耗水120kg;
十四,洗车:用抹布擦洗比用水龙头冲洗,至少每次可节水400kg;
十五,冲厕所:如果您使用节水型设备,每次可节水4一5kg;
十六,洗地板:用拖把擦洗,可比用水龙头冲洗每次每户可节水200kg以上;
节水的方法很多,只要我们做有心人 , 节约用水,利在当代,功在千秋
同学们只有从我做起,从现在做起才能维持我们人类生生不息,记住吧, 珍惜水就是珍惜我们自己的生命.我的演讲完毕,谢谢大家!
