大家下午好!矫健的苍鹰扇动着双翅，无畏的目光点亮前行的道路。呼吸一口新鲜的空气，让久储的梦想复活，让我们一起飞翔!信管04503班的杨国兴给您们带来最真挚的演讲。今天我演讲的题目是《而今迈步从头越》。
大学的我们渴望收获才华，学富五车。我们渴望搏击信息大潮，收获才能，引领it走向。胡适先生说过：“学问是铸器的工具，放弃了学问，便摧毁了自己。”然而，我们校园中出现有背于学校主流文化的现象，却不由得让我们重新进行了思考。我们的学生是否还怀有拼搏、收获的心，对待生活。
在课堂上沉浸在电脑世界、手机世界里的同学们，我们是否想过我们每天收获了什么?
在校园的幽僻处，总有几个‘人约黄昏后’，动情处他们竟会旁若无人。我们那样就不觉得惭愧吗?
此外，在宿舍里的‘腾云驾雾’，‘快活似神仙’，考场中的照抄作弊，熄灯后的大呼小叫。作为中跨世纪新一代青年就是我们这样吗?
我们可知道这样做对自己、对同学、对学校有多大的影响。断送了自己的学业，剥夺了同学学习的机会，影响了学校的学风建设。现在的社会是一个竞争的社会，没有过硬的本领，没有丰富的知识，是无法在社会上立足的。
生活腐化，追求时尚，崇尚名牌。玩物丧志，沉溺于网络世界。理性侏儒，缺乏判断能力和审美能力。学术精神的失落，道德低下，行为放荡，缺乏信仰，缺乏毅力，缺乏进去精神和承受力。如果您是老板，您会选择我们这样的员工吗?
同学们，看看吧!看看李开复教我们怎样度过大学四年。他说到：大学四年是人生中最关键的阶段。从入学的`第一天起，你就应当对大学四年有个正确的认识和规划。
同学们，醒醒吧!是该醒的时候了。不要被习惯所掩盖，被时间所迷惑，被惰性所消磨。让我们问问自己，我们对得起含辛茹苦的父母吗?如果父母知道我们在学校中的表现，父母是多么的伤心。同学们让我们拿起笔算一算四年我们需要花费多少钱，我们是否对的得起父母为我们付出的一切。
同学们，想想吧!是该想的时候了。罗马并非一日建成，成功更非一蹴而就。为了自己，为了在毕业以后找到好的工作。我们是时候该充实自己，完善自己了。
同学们，一起努力吧!只有全心奋斗，才有满心收获。

my definition of success
today i am very glad to be here to share with you my ideas of success. what is success? it is what everyone is longing mes success would be rather simple. winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now i am

complicated. is fortune success? is fame success? is high social status success? no, i don’t think so. i believe success is the realization of people’
s hopes and ys, in the modern society there are many people
who are regarded as the successful. and the most obvious characteristics of hem are money, high position and luxurious life. so most people believe that s success and all that they do is for this purpose. but the problem is wether it is real success. we all know there are always more money, higher position and better condition in front of us. if we keep chasing them, where is the end? what will satisfy us at last? therefore, we can see, to get the real success we must need something inside, which is the realization of
people’ hopes and ideals.
different people have different ideas about success; cause people’s hopes and ideas vary from one another. but i am sure every success is dear to everybody, cause it is not easy to come by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility. these are the best treasures. so now i am very proud that i have this opportunity to stand here speaking to all of you. it is my success, cause i raise up to challenge my hope.

a window is opened up at the crack of dawn, beside which one man is overlooking the the mess of buildings outside, breathing the fresh air cosily. but just after a little while, he steps to his seat, staring at the computer screen till the night. this man is very likely a programmer.
there is a man who concentrates on his computer, but doesn’t care about however he dresses, or even whether he washes his face.
there is a man who has a good knowledge of computer language, but has a low eq and makes a bad relationship with others.
there is a man who stays at home and does his own work by himself day and night, but just has few friends.
these images shown above probably are what people think of programmers as, in fact, programmers indeed give us a bad impression sometimes. however, people just have a partial understanding of programmers’ life, not to mention that they can know the fun of programming. there is no doubt that programs affect all aspects of our lives in an obvious or potential way, especially they are reflected in electronic products that we use nowadays.
when you are so proud of possessing an iphone, you’d better remember that it is the program that makes you get confidence to show off the advanced mobile phones thoroughly.
when you take advantage of computers to cope with problems in life, you’d better remember that it is the program that makes you seek the convenience of computer.
when you needn’t worry about hot summer and cold winter owing to an air-conditioner, you’d better remember that it is the program that makes you share the machine’s intelligent.
when you release your pressure by playing varies of online games, you’d better remember that it is the program that makes you enjoy the great entertainment in life.
as people’s thoughts control their bodies, computer programs play a leading role in the modern times. both social progress and human evolution depend on the computer programs. in the practical application, a software consists of different programs and then combines with hardware to develop into a high-tech electronic product. there are many kinds of electronic products found everywhere in our daily life. nearly all the time do we make use of these products to conduct our passion.

i have a dream
i am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation.
five score years ago, a great american, in whose symbolic shadow we stand today, signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of their captivity.
but one hundred years later, the negro still is not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. one hundred years later, the negro is still languished in the corners of american society and finds himself an exile in his own land. and so we've come here today to dramatize a shameful condition.
in a sense we've come to our nation's capital to cash a check. when the architects of our republic wrote the magnificent words of the constitution and the declaration of independence, they were signing a promissory note to which every american was to fall heir. this note was a promise that all men, yes, black men as well as white men, would be guaranteed the "unalienable rights" of "life, liberty and the pursuit of happiness." it is obvious today that america has defaulted on this promissory note, insofar as her citizens of color are concerned. instead of honoring this sacred obligation, america has given the negro people a bad check, a check which has come back marked "insufficient funds."
but we refuse to believe that the bank of justice is bankrupt. we refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. and so, we've come to cash this check, a check that will give us upon demand the riches of freedom and the security of justice.
we have also come to this hallowed spot to remind america of the fierce urgency of now. this is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. now is the time to make real the promises of democracy. now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood. now is the time to make justice a reality for all of god's children.
it would be fatal for the nation to overlook the urgency of the moment. this sweltering summer of the negro's legitimate discontent will not pauntil there is an invigorating autumn of freedom and equality. nineteen sixty-three is not an end, but a beginning. and those who hope that the negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to busineas usual. and there will be neither rest nor tranquility in america until the negro is granted his citizenship rights. the whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.
but there is something that i must say to my people, who stand on the warm threshold which leads into the palace of justice: in the proceof gaining our rightful place, we must not be guilty of wrongful deeds. let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterneand hatred. we must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. again and again, we must rise to the majestic heights of meeting physical force with soul force.
the marvelous new militancy which has engulfed the negro community must not lead us to a distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. and they have come to realize that their freedom is inextricably bound to our freedom.
we cannot walk alone.
and as we walk, we must make the pledge that we shall always march ahead.
we cannot turn back.
there are those who are asking the devotees of civil rights, "when will you be satisfied?" we can never be satisfied as long as the negro is the victim of the unspeakable horrors of police brutality. we can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. we cannot be satisfied as long as a negro in mississippi cannot vote and a negro in new york believes he has nothing for which to vote. no, no, we are not satisfied, and we will not be satisfied until "justice rolls down like waters, and righteousnelike a mighty stream.

hello,everyone. good afternoon. thank you for giving me this opportunity to talk about my top concern. i'm no.26, i'll talk about friend.
everyone of us,rich or poor,should at least have one or two good friends. my friend will listen to me when i want to speak, will help me when i need,will take care of me when i am sick,and my friends will go together with me side by side through this journey of life.
when i was ten, i was suddenly confronted with the anguish of transferring to other school. i had to left my friends i had ever known. as a kid,i feel lonely when i study in a new environment without a person i had known. nobody i could talk,nobody could know when i feel lonely. the time when i couldn't sleep, i'll always miss them, then the tears filled my eyes.
later, i became familar with the environment ,and made some friends ,which became my best friends then. they talked with me when i felt lonely, they helped me when i needed, they took care of me when i was sick. even through we were part, we still keep in touch with each other.
in our whole lives,we'll meet too much people but only a few can be our best friends. when staying with them,we can release ourself completely. we can do whatever we want, we can laugh together, talk together, and even cry together. i should say that being together with our best friends is the most wonderful moment of our lives.
but in this fast-developing modern society, the reality is not that. more and more people forget to enjoy the beauty of friendship. they work hard in order to gain a higher position in the society and to earn more money for their work. they have few time to share with their friends. with the time goes by, they will be far away from each other.
friend is kind of treasure in our lives. it's actually like a bottle of wine, the longer it is kept, the sweeter it will be. it also likes a cup of hot tea, when we are in bed time, it will warm our broken hearts.
friends,especially best friends. it is what we should have in our lives,and it can make our lives be colorful go beyond our imagination.
thanks for your listening. this is what i concerned.

尊敬的各位领导，评委，老师，亲爱的同学们，大家好!
我演讲的题目是“祖国在我心中”。
一把黄土塑成千万个你我，静脉是长城，动脉是黄河。五千年的文化是生生不息的脉搏，提醒你，也提醒我，我们拥有个名字叫中国。再大的风雨我们都见过，再苦的逆境我们同熬过。这就是民族的气节，这就是泱泱的气节，因为我们拥有一个名字叫中国!
祖国，当我们提起这个词的时候，我们的心中马上会联想到壮丽秀美的山川，历史悠久的文化，会联想到钢铁般的国防，善战的勇士;还有那鲜艳的五星红旗。对于家乡的山水，家乡的声音，语言，人们都会怀有一种特殊的感情，这种最深厚的感情，就是爱国之情最自然的流露。
那莽莽无际的原野，奔腾浩荡的江河，苍茫辽阔的草原，为我们提供了极为生动的情感素材，我们的祖先用勤劳和智慧，创造了中华民族灿烂的文明，在哲学，历史，政治，军事，文学艺术等诸方面取得了无与伦比的成就。所有这些都凝聚着一种民族的自信心和自尊心，它激励着人们把自己的智慧，力量以至生命毫无保留地贡献给祖国和人民。
5000年的文明孕育了中华民族的尊严，造就了中国人民独特的讲风骨，重气节的民族素质。历史仁人志士为国家前途，人民幸福，为坚守自己的志向，不惧困苦，不受利诱，保持铮铮铁骨的“浩然正气”。
从古至今，祖国就涌现出无数的爱国者，他们把祖国，民族的利益看得高于一切，把个人的命运同祖国民族的命运紧紧地联系在一起。如精忠报国的岳飞，收复中国台湾的郑成功，中国革命的先驱者孙中山，两弹一星的邓稼先，驾驶神州五号飞向太空的杨利伟，奥运新星刘翔等等……无数仁人志士以铁的事实抒写了一曲曲爱国之歌。他们为祖国生，为祖国死，把爱国之情化作英勇献身的实际行动，把为国捐躯，报国献身视为最崇高，最光荣的事情。
同学们，我们应该为生在这个英雄的国度而自豪，为这些民族之花而骄傲。
其实，爱国，不仅仅是对祖国的一种深厚的感情，它更是一种沉甸甸的责任啊。所以，同学们，我们要从小树立爱国精神。例如：在升国旗时，要行注目礼;团员同学日常生活中要爱护团徽，团证;平时要积极参加校内外开展的一切利于青少年成长的活动。虽然这些只是日常生活中的小事，但是却充分的体现出了自己的爱国意识。
此外，还要确立一个远大的志向，对自己的未来充满希望，要立志为祖国的未来而努力奋斗，把祖国建设成为物质文明，政治文明，精神文明的国家。因此，这就要求我们珍惜和抓紧现在的每一分，每一秒，抓紧锻炼身体，培养高尚的道德情操，掌握丰富的知识，要培养创造意识，为建设祖国，振兴中华做准备。

高考与成功没有必然关系，或者说大学层次如何与成功没有必然关系。
一个简单的道理，社会的杰出人才不都是清华北大毕业的。
大家熟知的马云就是杭州师范学院毕业的。我自己也是安庆师范学院毕业的，而我的同事一般都是安徽师范大学毕业的。我在这所学校教书也挺好，并不比他们差到哪里去。
客观上说，一个人成功需要多方面因素。从个人自身因素来看，我认为自身的非智力因素远远超过智力因素。我个人认为成功需要三个条件，一是主动，二是坚持，三是规划。
我走到现在，与这三点有密不可分的关系。从这三点来看，没有哪一点与智力因素有关，与所上的大学有任何关系。
实际上，即使上同一所大学，经过四年学习结果也不一样。大家都知道经过高中三年的学习，高考的结果不同。大学相比较高中，自由度更大，形成的差异相应会更大。同样是上大学，有的同学是在网吧呆了四年，有的在读书馆呆了四年，还有的同学发传单发了四年。有的同学成了人才，有的同学成了木材。
现在社会，很多岗位是没有什么专业需求的。我老婆原来在行政服务中心，其主要工作就是审核盖章。这样的工作，我感觉一个初中生读都能够完成。这时候态度就很重要了。我个人理解，专业性强的，大学比较好的侧重于专业水平，专业性不强，大学不怎么样的侧重于综合素质。如果从事的是高科技的专业技术类的，也许只需要专业素质强就行了，一般的大学就要注重个人非智力因素的提升。
所以，高考与成功没有多大关系，大学的层次与成功也没有必然联系。高考仅仅是人生的开始，而不是结束。千万不能把自己未来的几十年时间用现在十几年的时间来决定输赢。人生的路还很长，能够改变的还很多。
更重要的是拥有一颗积极上进的心，不断学习、完善自我，找到自己的兴趣，做自己喜欢的事情，做对别人对社会有用的事情，成功必将属于你!

细节决定成败，精益求精争创一流业绩。有哲学家说过：细节差之毫厘，结果谬之千里，真理和谬论往往只有一步之遥。相信大家都有过这样的体验：一个错误的数据可以导致病人死亡，一个标点符号的错误，可以使几个通宵的心血白费，一篇材料的失误，可以使若干年的努力泡汤，而人生紧要关头一步踏错，可以使一生的命运彻底改变。这就是细节的重要，这就是精细的力量。我们战斗在一线的员工，更要加强细节观念。将细节决定成败的理念引入实际工作中。从细节入手，在细节中挖掘潜力，以认真的态度做好工作中的每一件小事，只有这样，才能在每一个平凡的岗位上发挥最大的作用，只有这样，才能为我们社会创造出更大的经济效益。
当你不厌其烦地拾起细碎的石块日积月累构筑起来了的却是高耸的城堡，只有站在城堡俯瞰脚下的壮美景色时，你才会体味到这些小事的重要。正所谓，细微之处见精神，人人都应从小事做起。
小事不能小看，细节方显魅力。以认真的态度做好工作岗位上的每一件小事，只有小事做好了，才能在平凡的岗位上创造出最大价值。“以管窥豹，可见一斑”。我们往往可以从生活中的一些微不足道的小事洞察秋毫，从而感悟到一个人的内在精神。
海尔集团总裁张瑞敏说：“什么是不简单?把每一件简单的事做好就是不简单;什么是不平凡?把每一件平凡的事做好就是不平凡。”让我们以此共勉。
我的演讲结束，谢谢大家。
学生即兴演讲比赛稿范文篇2
尊敬的各位领导，老师，亲爱的同学们：
大家好!我今天演讲的主题是“感恩，是我们人类最美好的品质”。 俗话说得好，男儿膝下有黄金。可是每一年，我都要在同一地点下跪。为何呢?每一年的清明，一个坟墓前，我们全家人都行三跪九叩之礼。因为坟墓里面住着我的爷爷。
鲜花感恩雨露，因为雨露滋润它成长;苍鹰感恩长空，因为长空让它飞翔;高山感恩大地，因为大地让它高耸。我们感恩父母，因为父母把我们带到这个世界，含辛茹苦地把我们养大成人，给了我们一个温馨的家。
先给大家说一个我自己的故事吧。一次，我爸爸开摩托车载着我出门。途中突然下起了大雨，幸好的是我们有一件单人的雨衣。我只有压低头，伏在我爸爸的背上。我无意中看到雨水从我爸爸的发白的头发上滴落。我的心顿时很温暖，甚至温暖到有点想哭。父母给我们的恩情，我们难以报答。在父母进门后，我们送上一双拖鞋;在父母下班之后，我们给他们捶捶背;在和父母讲完电话之前，我们提醒他们要注意身体。感恩不需要多么华丽，多一句问候，多一点关心，就可以让我们的父母的心温暖好几天。
再来看看我们的社会。比如某某地方发生自然灾害了，就会有很多慈善活动，为灾区筹款，为灾区的人们送上一份温暖。其实慈善，也是感恩的另一种方式。比尔和梅琳达·盖茨基金会是由比尔·盖茨与梅琳达·盖茨夫妇资助的、全球最大的慈善基金会。该基金会主要在以下几方面提供援助：全球人的健康，教育，图书馆，美国西北部的建设等等。而且比尔盖茨在退出微软的时候把580亿美元个人财产尽数捐到比尔与美琳达·盖茨基金会。当然，我们的慈善活动没那么惊天动地。我们可以向需要帮助的人捐助钱财，衣物，默默为他们祈祷祝福。可是，对于那些披着慈善的外表，对筹款中饱私囊的组织，我们坚决抵制。我们可以得出这么一个结论：任何不以感恩为目的的慈善活动都是耍流氓!
假如今个学期你不小心旷了几次课，被老师记录下来了。结果最后考核没过，要重考。再一个不小心，重考也没过，要清考。是老师记录你旷课才导致你这门课程没有通过。你是不是不需要感恩于他呢?其实不然，我们更应该感恩那些曾经伤害过我们的人，因为他磨练了我们的意志;感恩那些曾经欺骗我们的人，因为他增进了我们的见识;感恩那些曾经斥责我们的人，因为他强化了我的能力。所以，你应该对这位老师心存感激之意，因为他在警醒你：不要再旷课了!
滴水之恩，就应涌泉相报。感恩是我们人类最美好的品质，我们要学会感恩。常怀一颗感恩之心，不要时刻想着回报，我们会更加阔达，这个世界会更加充满爱。
在我演讲结束之前，我想衷心的感谢在场的各位，感谢你们聆听我的演讲，感谢你们给予我支持的眼神。我的演讲到此结束，谢谢!

尊敬的评委、领导：
大家好!很高兴站在这里发表演讲，我今天演讲的题目是《发扬亮剑精神，构筑和谐工商》!
电视剧《亮剑》中的主人公李云龙曾说过：“面对强大的对手，明知不敌，也要毅然亮剑。即使倒下，也要成为一座山，一道岭。”正是凭着这股不畏强敌敢于亮剑的精神，他们一次又一次地战胜了装备精良的强敌。在发展社会主义市场经济的大潮中，要维护市场的公平正义，要构建和谐的工商，红盾卫士仍然需要这种敢于亮剑的精神。
亮剑就要有剑胆。和谐工商不是一团和气，作老好人，对尖锐的矛盾、激烈的冲突视而不见;和谐工商也不是一帆风顺、一马平川。君不见，直面惊涛拍岸的商海大潮，那极不和谐的调子不时在你身边敲打吗?商业贿赂、欺行霸市、假冒伪劣，短斤少两，坑蒙拐骗……这一切，不都在向我们昭示红色盾牌的使命吗?维护国家尊严，确保市场繁荣，市场监管是我们工商人永恒的主旋律!
不亮剑等于虚设，不亮剑等于渎职，不亮剑等于残疾!作为一名工商人，我们“红盾”的利剑要毫不留情地刺向扰乱经济秩序的黑暗角落。“亮剑”中我们是会得罪一些人，也会受到五花八门的威胁、恐吓，甚至有着暗藏杀机的较量。但我们始终以大无畏的气魄去面对工作中的各种困难和威胁，这就是亮剑精神的剑胆。发扬“逢敌必亮剑，剑锋所指，所向披靡”，敢打硬仗、能打胜仗、屡破强敌、所向无敌的亮剑精神，真正做到“情为民所系，权为民所用，利为民所谋”，才能在监管社会主义市场经济中尽职尽心，才能在构建和谐工商的进程中大显身手。
亮剑就要精剑道。亮剑不但要有胆量，还要有过硬的本领。本领硬、底气足，才是必胜的法宝。作为一个工商人，仅有热情和勇气是不够的，更应具备广博的知识和多方面的才能。随着市场经济的发展，经济违法的手法越来越隐蔽，案情也越来越复杂，执法程序也日益规范化，这对我们工商人能力素质的要求越来越高。以前“一说二吓三罚款”粗糙的行政执法手段将一去不返。
“剑出有名，依据是法律;剑出有路，要有程序和招术;剑出有效，要达到预期的社会效果”。亮剑精神是一种智慧的艺术，我们在经检办案过程中应当学会剑“亮”在何处，剑怎么“亮”，做到断然出手，一击必中!我们工商人要把亮剑精神贯穿于不断的学习中，提高自身的业务素质和执法艺术水平。只有精于剑道，才能使自己真正成为执法工作中的行家里手;只有精于剑道，才能在构建和谐工商的重任下游刃有余。
亮剑就要扬剑威。威从何来?工商人的威信应当来自为民为国依法行政的自豪感;来自公开透明、廉正生威的执法理念;来自执行法律法规规定，遵循办案程序，严守办案纪律的阳光办案;来自紧要关头，危难时刻，勇于负重，挺身而出。刚直不阿、客观公正、临危不惧，面对失误不推诿、敢于承担责任，只有这样，工商人才能在社会主义市场经济监管中，树立起行政执法监管的权威，才能经受得起社会各界的监督，才能在构建和谐工商的工作中得到人民群众的热烈拥护。
亮剑更要讲剑义。严格执法是我们的职能和职责所在，但法与义并非水火不容。在构建和谐工商的工作中，努力达到人性化执法与严格执法的有机统一，是我们工商人共同的目标。“群众利益无小事”，维护业户和消费者权益是我们时刻放在心上的大事。
我们的行政执法要提倡剑胆琴心。“琴心是职业操守，琴心要以人为本，琴心要文明执法”。正确处理严格执法与热情服务的关系，打造和谐执法氛围，以服务市场主体和创造良好发展环境为目标，进一步优化工作职能，维护、发展、实现好各类市场主体和消费者的利益。加强队伍建设，创新监管机制，打造诚信工商，转变工作态度，树立文明执法形象。
发扬亮剑精神，做到有剑胆、精剑道、扬剑威、讲剑义，工商人更有作为，更有地位，定能不辱使命。让我们亮起工商之剑，让红盾之魂在和谐工商的光辉照耀下闪光吧

尊敬的各位评委、老师、亲爱的同学们：
大家上午好!
我是~~~区第一小学的~~~。我演讲的题目是<水，无可替代的资源!>。上台之前，辅导员老师担心我紧张，递上这一瓶水。喝上一口，我干渴的喉咙顿时得到了润滑。我相信，您能在30秒钟内说出水的十几种用途。洗手，洗脸，洗脚，洗头，解渴，养小鱼，浇花……
是啊，水，是如此重要!
水是生命之源。哪里有水，哪里就有生命。水分约占到人体体重的65%。一个人如果缺水5%，就会出现意识不清，甚至幻视;没有食物，人最多可以活两个月，如果没有水，顶多能活一周左右。水是庄稼的命根子。用手抓一把植物，你会感到湿漉漉的，凉丝丝的，这是水的缘故。水是工业的血液。制造1吨钢，大约需用25吨水。制造1吨纸需用450吨水。食品加工离不了水，酱油、醋、啤酒等，干脆就是水的化身。有水走遍天下，无水难成美景。水路运输便宜，运输量大，平稳，还是不会被炸断的运输线。你看，钱塘江大潮、珠穆朗玛雪峰、黄山的云海、哈尔滨的冰灯，哪一个不是水的换景变形?游泳、跳水、冲浪这些人们最乐意的活动，哪一个离得开水?
可是在一些缺水地区，能让孩子喝上一口净水、洗个澡，是众多母亲的奢望。一个老农用一根粗粗的绳子把一个七八岁大的孩子滑到深深的井底，为的只是一瓢一瓢舀上半桶略带泥沙的饮用水。农户在锅里烧开水的时候，锅的一圈竟然是泛白的碱性沉淀物。再看我们身边：哗哗的流水，为的是洗一块毛巾!烈日炎炎的夏天，当你舒舒服服地冲着凉水澡时，你所用的水是缺水地区几十人的一天的用水量;当你冲洗马桶时，一次的用水量当于发展中国家人均日用水量;当粗心的你没有拧紧水龙头，它一个晚上流失的水，相当于非洲缺水地区一个村庄的居民一天饮用水量……
同学们，没有电灯，我们可以点蜡烛;没有蜡烛，我们可以点油灯;没有油灯，我们可以点火把;连火把也没有，我们只好静静地等待黑夜过去，黎明的到来。而没有水，我们无法洗脸、刷牙，无法解渴，餐桌上没有了鱼虾，看不到花草树木，不知道什么叫游泳，船舰全部报废，高楼无法建，连小娃娃的哭也没有了眼泪啊!
在建设的进程中，我们也许还不能理解“和谐”的深刻内涵，但我们相信当我们关掉哗哗流淌的水龙头，这就是和谐;当我们洗完手之后，关紧水阀，这就是和谐;当我们循环使用水，就是和谐。
亲爱的爸爸、妈妈、叔叔、阿姨，我们需要的不仅是新衣、美食、上最好的大学，走最宽的马路，住最大房子，更需要的，是一个充满希望的未来!您看这晶莹剔透的水，滴滴都珍贵。为了我们自身的健康，为了子孙后代的幸福安宁，为了人类今后的生存和发展，请您节约每一滴水!
