大家好!
仰观宇宙之大，纵论古今名人，凡是功成卓绝之人，他们都有一个成功的秘诀，那就是坚持!
坚持是取得成功的必备素质。它犹如一条红线，贯穿了始终，是长久不变的意志表现。“骐骥一跃，不能十步;驽马十驾，功在不舍。锲而舍之，朽木不折;锲而不舍，金石可镂!”这句话充分说明了一个人如果有恒心，一些困难的事情便可以做到;没有恒心，再简单的事也做不成。
总览古今中外，大凡有成就的人，无不具有坚持的精神。《史记》这部鸿篇巨著被世人称之为“史家之绝唱，无韵之离骚”，可你知道，它是司马迁耗费了17年的时间，不顾宫刑的折磨，呕心沥血的杰作。更有李白铁杵成针，屈原洞中苦读，匡衡凿壁偷光，他们的精神印证了“贵有恒，何必三更五更睡，最无益，只怕一日曝十日寒”的真理。他们用行动告诉我们，只要有滴水穿石的精神，持之以恒，成功不会遥远。英国首相丘吉尔在面对德国法西斯的疯狂进攻时，就曾对他的国民说过：“不要屈服，永远不可屈服。”这不但是一句振奋人心的豪言壮语，也是他最重要的人生总结，体现了他坚持到底的精神。大家都熟悉愚公移山的故事，愚公之所以能够感动天帝，移走太行、王屋二山。正是因为他具有锲而不舍的精神。可见，成功离不开坚持。
学习也一样，学习不是一朝一夕的事情，学习中感到枯燥在所难免，很多人都因半途而废，而最终一无所获或收益甚少。不少同学知道学习很重要，但是学习累了，作业多了，就失去学习的兴趣，就变得懒惰。究其根本，就是缺乏持之以恒的精神。学习需要恒心，需要持之以恒。在任何条件下，都向着自己的奋斗目标坚持不懈地努力，永不退缩。如果在学习中总是知难而退，半途而废，那么就永远不会取得好成绩。在学习中，我们要坚持把每一课学好，坚持克服每一个困难，坚持地朝自己定下的目标前进，总有一天可以把铁杵磨成针，把金石打磨穿。学习很苦，却又不苦，只要有坚持不懈地决心，那些学习中的困难也不过是脚下一粒石子，如果遇到困难就放，那困难就是眼前的高山。
蜗牛坚持着爬上金字塔顶得到了雄鹰的世界;乌龟坚持获得了兔子的荣誉;愚公坚持而让山移。只有坚持，才能开启成功的大门，我们要学有所成，就要坚持学习。同学们，学习中就要有毅力，有恒心，相信“锲而不舍，金石可镂。”让我们站在此刻的起点上，坚持到底，永不言弃。珍惜初中剩下的时光，用今天的刻苦，铸就明日的辉煌!
谢谢大家!

dear teacher, my dear students:
good morning!
i come from class ? grade ?, my speech is entitled "i love my school."

gradually opening night, the morning mist at the vast expanse of whiteness receded, at the flow. at this time, there have been at the morning mist of vague shadows, one, two ... five ... ten ... ... in droves, accompanied by cheerful laughter, walked into the campus.

i love our school! i love our teachers!

尊敬的各位领导、老师，亲爱的同学们：
水是大地的血脉，它滋润着崇山峻岭，灌溉着良田;水是一切生命的源泉，它养育着飞禽走兽，哺育着花草树木;水是人类文明的摇篮，在人类文明的发展，因为水环境的变化，导致一个国家一个民族盛衰变迁的例证举不胜举。源远流长的中华文明，也正是依存长江、黄河等母亲河的支撑，而发展下来的。
长期以来，人们普遍都认为水是“取之不尽，用之不竭”的。其实我们地球虽被称之为“水球”，但其淡水储量却是少之又少!水资源并不是“取之不尽，用之不竭”的，水将成为21世纪威胁世界和平影响社会发展的障碍。
所以在全球的水资源危机日益严重的情况下，节约用水便成为每个公民应尽的职责。尤其在中国，水资源的人均占有量并不丰富，淡水资源不到世界人均水量的1/4;地区分布并不均匀，年内变化莫测，年际差别非常之大，每年受旱农田32亿亩，约有5000万人和3000万头牲畜面临水荒。再加上污染，使水资源更加紧缺，所以人们更应该节约用水。如果大家能够从我做起，从现在做起，从身边做起，牢固树立节约意识，从节约一滴水、一粒米、一度电、一张纸入手，把节约落到实处。如果这样，对学校来说，那将是一笔可观的财富，对于我们这个13亿人口的大国来说，那就是一个惊人的数字。
节约是一种美德，节约是一种智慧，节约更应该成为一种习惯和风气。建设节约型社会需要全社会的共同参与和共同行动，找回失去的节约意识，从身边的点点滴滴开始，持之以恒，在建设节约型社会中，将节约这个“传_”进一步发扬光大!
只要大家都注意节约用水，水荒才会远离我们，我们的生活才会安定、和谐;环境才会优美、舒适。同学们明白这个道理后，一定要自己身体力行才行!什么叫爱国、爱校、爱家，不是天天喊在嘴上，而是要落实在行动中。如在家中、在学校节约用水这就是爱国、爱校、爱家的具体表现。
作为当代的中学生，我们应该弘扬中华之美德，节约身边之滴水。
莫让人类的眼泪成为地球上最后一滴水!
谢谢大家!

尊敬的老师、亲爱的同学们：
大家上午好!
亲爱的同学们，当你踏着晨光走进我们花园般的校园时，当你坐在干净整洁的教室里学习时，你是否想到老师、同学们为此的辛勤付出?
我们都渴望校园中能有郁郁葱葱的草地，都期盼在整洁干净的环境中学习、玩耍，都希望在舒适温馨的宿舍里进入梦乡。
可是却有同学不懂得珍惜这些美好的事物。请同学们放眼校园仔细看看——那洁白的墙壁被打上了鞋印、球印;桌椅上留着乱涂乱画的痕迹;水龙头开着，让水肆意的流失;美丽的草坪、花圃上留着无情的脚印;塑料袋、包装盒、果皮纸屑扔得满地都是，在其他同学午晚休的时候，宿舍楼内外高声的喧哗，打破了这一片宁静。这些现象与我们美丽、文明、和谐的校园多么不协调!
我们崇尚文明，我们都需要生活在干净、整洁、美丽的环境中，然而，为什么我们总把打扫、维护的希望寄托在别人身上?为什么总是毫不怜惜的践踏这片宁静与美丽?为什么总是逃脱作为_中一份子的责任?
同学们，立即行动起来吧!一片纸，我们捡起;一滴水，我们节约;一堆垃圾，我们打扫，爱一棵小树苗，保护一只小青蛙。为了我们的校园，做我们能够做的一切。“勿以善小而不为，勿以恶小而为之”。为此我向_中全体同学呼吁：创建清洁、文明的校园，需要你，需要我，需要我们大家共同的努力。让我们积极行动起来!让我们从现在做起，从身边的小事做起，加强自我约束，相互监督，争做保护校园环境的小卫士。
我的演讲完了，谢谢大家!
上课即兴演讲篇五
needless to say, money is not very important, but very very important.
if there is no money, i can’t use this microphone to speak to you and we can’t have such a room to hold such a competition. without money, we can’t study in such a schoolyard. without money, we can’t live in such a hometown. without money, we can’t have such a motherland. on the other hand, if there is no money, you don’t need to bear my speech about money now.
most of us have dreams about the future, dreams of having a good job and making much money. surely someone has thought at times “if only i had a lot of money, i could be the happiest person in the world.” in fact it’s the main mistake that people make about money.
however, is money the road to happiness? not really! many people work every day, work overtime, work weekends to make a lot of money. are they happy? no. they are too busy making money. meanwhile, their personal lives, if they have any, fall apart. they have no time to form or to maintain friendship. they even lose the abilities to relax and to enjoy themselves. enjoying means taking things, taking time to see, to hear, to taste, to smell, to feel. they do not take time to do this. they say: “i’ll do it when i have enough money to retire” then they find that it is too late.
why we usually make such a mistake and even more mistakes? activists say it is because of money itself. they think money has changed many things. for example, they think money has changed our way to measure someone’s value in the society. they even regard money as the source of evil. also, they hate money, but they are wrong, completely wrong.
in my opinion, it is unfair to money. money is a tool. well, there’s no denying that we do something harmful with money. but we can’t say money is the source of evil. just like a hammer, we can use a hammer to kill someone, but can we say a hammer is a devil? it is the same with money.
money is neither good nor bad itself. it is a mirror, a perfect and important mirror, and a mirror that reflects both the darkness and the brilliance of humanity. in other words, all depend on us.
so, my fellow students, ladies and gentlemen in the future, ask not what we can do for money, ask what money can do for us, ask what money can do to show the brilliance of humanity. because, we have the future; we are the future.

if you want to be more successful, if you want to have and do stuff you never done before then i’m asking you to invest in you!
someones opinion of you does not have to become your reality.
you don’t have to go through life being a victim. and even though you face disappointments, you have to know within yourself that ‘i can do this, even if no one else sees it for me, i must see it for myself!’
no matter how bad it is, how hard it gets, say to yourself, i’m going to make it!i wanna represent an idea. i wanna represent possibilities. some of you right now, you wanna go to the next level. you wanna be a civil engineer, you wanna council, you wanna be a to me: you can’t get to that level. you can’t get to that level until you start to invest in your mind
i dare you to invest in your mind.
i dare you to invest time.
i dare you to be alone.
i dare you to spend an hour alone to get to know yourself.
i challenge you to get to a place where people do not like or do not even bother you anymore. why? because you’re not concerned with making them happy anyway. because you’re trying to blow up. you’re trying to get to the next level. because you’re investing in your mind.
if you’re still talking about your dream and your goals but you have not done anything just take the first step.
