课堂3分钟演讲稿篇1
亲爱的同学们：
大家早上好!今天讲话的主题是“爱眼护眼，拥有一双明亮的眼睛”。
眼睛是心灵的窗户，人人都希望有一双明亮的眼睛。透过这双眼睛可以看到五彩缤纷的大千世界，但现在，清晰的世界离我们越来越远。我说几种情况，它们有没有发生在你身上——看书写字时紧盯着书本，没有离书本一尺远;看电视、用电脑时紧盯屏幕，并且时间超过1个小时;在强光或昏暗的地方走路、坐车的时候看书写字。孩子们想一想怎么办?也许有的同学错误地认为“只要我学习好就行了，视力不好配戴眼镜就行了”;还有的小朋友认为戴眼镜是有知识的象征。但是现实告诉我们：一旦患了近视，戴上眼镜会给学习和生活带来很多不便。例如在参加体育活动的时候，打篮球或踢足球时，打破眼镜甚至伤及眼睛到医院做手术缝合是常有的事。戴上眼镜如果仍不注意用眼卫生，常会使视力下降加快，形成高度近视。
接下来，蒋医生给同学们几条小建议，来帮助大家爱护眼睛：
1.认认真真地做好眼保健操，注意眼睛卫生。
2.养成良好的读书习惯，做到“三个一”，眼离书本一尺远，手距笔尖一寸远，胸离书桌一拳远。
3.做到“三不”：不躺着看书，不在行走中看书，不在光线弱或过强的地方看书。
4.阅读时间请勿太长：无论做功课或看电视，时间不可太长，以每三十分钟休息片刻为佳
5.保证充足的睡眠。
6.多做户外运动，经常远眺，使眼睛得到休息，调节视力，解除疲劳。
孩子们你们还知道吗?眼睛是人类感官中最重要的器官，大脑中大约有一半的记忆和知识都来自于眼睛。我们有什么理由不保护眼睛呢?
常言道：冰冻三尺非一日之寒，水滴石穿非一日之功，保护眼睛也不是一朝一夕就能做到的，注意用眼卫生、科学用眼贵在坚持，需要持之以恒，才能预防近视的发生及近视程度的加深。
婀娜多姿的自然，绚丽多彩的万物，一切的一切都需要眼睛来观察，同学们，让我们一起努力爱眼护眼，拥有一双明亮的眼睛。

林中的通幽曲径，因为那些曲曲折折的转弯才更富诗意与浪漫，一部扣人心弦的电影，往往是情节一波三折，令人回味犹有余香。我们的生活中，许多东西因转折而显得愈发美丽。
一本书因转折而精彩。《飘》中的女主角思嘉丽由一位娇弱的千金小姐因时代的变动以及身体内自尊的血液而转变成了坚韧而真正美丽的铿锵玫瑰，这样的蜕变真实而精彩，这样的转折使《飘》成为一部掩卷难忘的经典之作。《呼啸山庄》中，男主角希剌克利夫，由一个单纯、爱意绵绵的少年转变成了一个因爱而泯灭了人性的复仇恶魔，这场因爱而起的悲剧摄人心魄，因为这转折突然而精彩，这样骤变的人性更是突出了爱在他心底炮烙的深刻印记，更多的如希区柯克、欧?亨利那种出人意料的结尾处决定性的转折更是蕴藏着无穷的魅力。这些作品的转折，我想无论是美好或惊艳，都会令我们最大限度地体会到作者的用意，从而获得思考，它们无疑是精彩的。
文学作品中的转折多半是虚构的，人生中的转折却是真实的。虽然，有的令人痛不欲生，但其最终却成为铸造生命奇迹的一块块基石。司马迁在《史记》中写道：文王拘而演《周易》仲尼厄而作《春秋》;孙子膑脚，兵法修列，左丘失明，厥有《国语》;韩非囚秦，《说难》;《孤愤》……许多先贤都是在经历了如许苦痛的转折之后，更深刻地体味了人生的大义所在，依靠惊人的生命力延续了生的意志，写下了一篇篇传世经典，造就了一番番奇功伟业。就是在这些转折中，先哲们的坚韧和坦荡，使他们的人格和思想在历史长河上空凝聚成了一瓣瓣恒久的心香，也正是这些转折，激发了更多人更多的感喟……
记得林清玄说过生的路上，并不是你在哪里放上一个门框，那里就是唯一的出口。你可以向左向右转个弯;去寻求生命的出口。是啊，我们的生活之路一定不是平坦笔直的。有的转折也许是不情愿的，就如自己孩提时得知要离开居住已久的城市迁往北京时，心中的那份不快一样，不愿意离开相处已久的亲朋，对每一条街道，甚至是街边的陌生人都有一分不舍，毕竟没人愿意面对离别。到了北京后慢慢地适应了，认识了新朋友，生活有了新的精彩。这样的转折，乍看不美好，似乎是一种结束，如今想来，反到觉得是一个起点。
生活中的转折，快乐或痛苦。我们都应该微笑着面对，生活本来就有起有落，我们也应该如此看待生活。愿一个个转折为你我交织出一条值得回味的生活之路。

i often wonder what friendship is. friendship is too big a topic to talk about either specifically or generally. i guemost of us are still in a puzzling state about what friendship is, and i myself should be included. maybe people who define friendship according to his own life experience will say that they have a good concept of friendship, which i think is too narrow to get an objective definition of it. but how hard it would be to talk about friendship without mixing personal feeling in it, especially when it comes to the matter of closest friend. so here i would like to share my views with you about friendship, about my closest friend. i have had friends since i was born, some of whom have come along with me through my life, and it is impossible to always keep your friends around you since departure is one part of life that everybody must experience. though some of you may oppose me by exaggerating the connotation of the concept of being together that is friends may not stay together physically but they can stay together always psychologically,
i still hold that departure is an absolute thing. how could it be possible that your friend (even your closest friend) always keeps you in heart as he/she had, is having and will have different experiences from yours? somehow different experiences make up of different hearts. mansquo;s heart is a quite strange thing. never think that one can wholly touch it. sometimes our heart is so abstract that you donsquo;t even know how to get to them. if we take heart as a cube, and closest friend a gentle breeze, this breeze can only blow one facet of this cube from one direction and can rarely reach any other sides of your heart. isquo;m not sure whether i have put it very clearly but believe me that there are no fixed closest friend in your life. with different time, place, space, emotion and situation, you have different closest friends. when i play basketball, i have a closest friend who knows how to cooperate with me and together give our opponents a deadly attack; when i am alone and feel so lonely, i have a friend who can always comfort me by saying that he is my friend; when i am in need of money, the one who comes all the way and lend his money to me without any hesitation is my closest friend;
when i am proud and a friend dares to stand out to warn me that i should keep modest, he is my closest friend; and, when i read old man and the sea, i think hemingway is my best friend. you see then, how many closest friends i have. but i must say, though i always want to keep all of them in my heart, they are not actually always in my heart. they have their own friends and their own life. winston churchill once said that theresquo;s no perpetual friend, nor perpetual enemy, only perpetual interest. i guehesquo;s right in some way.personally i think it is a shame for people who take a pet as his closest friend as this is a sheer insult to human being and an absolute indignity for the word friendship. if a dog is his closest friend, what is human to him? you can imagine how would a person with his animal closest friend do to people. and maybe sometimes a dog can give him mental comfort, but what a dog likes best is just a bone. friendship is indeed an inborn desire of mankind, and it is relationship between people, not between people and animals. if you seek friendship, please seek it from people, from people around you.actually i have much more to say but… your criticism welcome!

那是珠迸于玉盘，露泣于香兰，凤鸣于东山，龙啸于天穹。时疾时缓，时扬时抑，时为流水潺湲，时为泰峰崩裂，他手一拂，弦一动，曲曲心律便已洒遍竹篁，竹帘微挑，清风徐入，他双目微瞑，只付心事于瑶琴。
帘外，正有三人跪坐，一人长鬓凤目，一人髭须半白，皆有不耐之色。唯有正中一人，恭敬不失傲骨，谦和不逊风雅。弦音漫漫，满室萦人。大哥，此人可能拉百石强弓，射靶于六百步外?翼德怒问，刘备摇头。大哥，此人可能持千斤刀戟，冲杀于百万军中?云长奋起，刘备摆手。大哥，那你何必在此苦求。他的架子也太大了，且待我一根麻绳缚来与你。翼德转身欲出，云长疾步相随。慢!刘备大喝：三弟不可鲁莽!
香火微明，弦丝慢转，时有鸟雀啁啾，往来轩外。诸葛昂首，依旧阖目，只唇边隐有笑意。
苔痕上阶，草色入帘，张飞怒气而立，关羽不满侧首。玄德一叹，坐相愈恭。若论弓拉百石，箭无虚发，执戟万斤，冲于严阵，谁又能较吕奉先一二?然纵横不过数载，祸患已有万端，白门楼上，英雄气短，如今安在?方天画戟不知谁手，赤兔宝马另载新主，能有谁顾忌百万军中，当年哪一骑当先?
关羽沉吟不语，翼德面有愧色。那大哥是重智而轻勇了?
非也!刘备哂之：天塑雄才，有文士，有武师，能文则潜心书海丰盈谋略;能武则醉于剑舞精进射骑。天下英王，不过择文武而用，即可位重九鼎。
弦音忽急，动于雷霆，人皆屏息。声愈促，弦愈急，霎时戛然，满室静寂。
先生好曲!刘备击节而叹。
诸葛转身而出，手捧瑶琴：使君高才，亮受教颇多。若论武斗，使君二弟已为良将，亮愿填补文才，竭尽愚智，以报使君知遇之恩。旋即长拜。
刘备忙前趋相扶。诸葛抬眸笑望关张：将军，可知琴曲之道?若六弦齐长则弦一律，无调。只有六弦各具长短，长为长，短为短，方能蕴声制律，并创长短参差之声。亮与将军各有所长，各有所短，愿各避其短，扬其长。如此笙琴长短相备，则可高可低，可伸可聚，纵横天下，莫能及也。
关张相视，释然一笑，刘备拊掌，众皆欣然。
卧龙居内，弦音再漾，羽扇轻摇……

most people would like to be popular with others, but not everyone can achieve this goal. what is the secret to popularity? in fact, it is very simple. the first step is to improve our appearance. we should always make sure that we stay in good shape and dress well. when we are healthy and well'groomed, we will not only look better but also feel better. in addition, we should smile and appear friendly. after all, our facial expression is an important part of our appearance. if we can do this, people will be attracted to our good looks and impressed by our confidence.
another important step is developing more consideration for others. we should always put others first and place their interests before our own. it's also important to be good listeners; in this way people will feel comfortable enough to confide in us. however, no matter what we do, we must not gossip. above all, we must remember to be ourselves, not phonies. only by being sincere and respectful of others can we earn their respect. if we can do all of the above, i am sure popularity will come our way.
we've all been taught that we should help people. it is the right thing to do and will make us popular with others. it may even win us favors in return. however, we must be realistic. we can't say yes to every request. if we did, we would fail or go crazy for sure. sometimes we simply don't have the time to help. in this case, we must know how to say no politely.

students, guests , teachers and honorable judges
good morning !
my great pleasure to share my dream with you today. my dream is to become a teacher…
as the whole world has its boundaries, limits and freedom coexist in our life. i don't expect complete freedom, which is impossible. i simply have a dream that supports my life.
i dream that one day, i could escape from the deep sea of thick schoolbooks and lead my own life. with my favorite fictions, i lie freely on the green grass, smelling the spring, listening to the wind singing, breathing the fresh and cool air and dissolve my soul in nature at last. simple and short enjoyment can bring me great satisfaction.
i dream that one day the adults could throw their prejudice of comic and cartoon away. they could keep a lovely heart that can share sorrow and happiness with us while watching cartoon or doing personal things. that's the real communication of heart to heart.
i have the belief that my dreams should come true. i am looking forward to some day coming when i am like a proud eagle, which flies to the blue and vast sky.

尊敬的老师们、亲爱的同学们：
大家好！今天我演讲的题目是“养成雅行习惯，争做文明学生”。
我们的祖国自古以“礼仪之邦”着称于世，我们的民族历来十分注重言行雅致。古时的孔融四岁就知道让梨，这个故事妇孺皆知；今天，我们伟大领袖毛主席行雅德馨：一九年回故乡，邀请尊长吃饭敬酒时，老人们说：“主席敬酒，岂敢岂敢！”毛主席回答：“敬老尊贤，应当应当！”谦谦君子风度传为美谈。
现实生活中，我们也许有青年旁若无人地占据着公汽的老弱病残座位，也许有外表靓丽的姑娘嘴里吐出“他妈的”叫声，也许有遇到路人撞了你不道歉便扬长而去，也许有衣着光鲜的行人边走边随地吐痰丢果皮。看到这些不雅的言行，你一定会觉得他们与物质文明的社会是多么不协调！是的，当今有些人对于自身不雅行为不以为怪，还会认为：小节无碍大事！我以为：言行文雅不是小事，它是一个人素养的体现，它是一个社会文明程度的标志。
可以这样说，雅行是现代文明人的重要素质，它比人的智慧与学识还要重要。举止文明、彬彬有礼、温文尔雅、仪态万方，这些美好的词语都是雅行写照。生活在社会的大家庭中，文明雅致地处事待人，是我们每个青少年成长过程中的必修课。我们更不能忽视，不雅的行为时常发生在大家的身边：校园内，有我们不经意丢下的垃圾；同学间，话语里也有脏话、粗话的字眼。虽说这只是一些小小的毛病，但却影射出我们素质上的缺陷。
同学们，我们1207班有一个共同的信念：今天，在校园学做文明人；明天，在社会上做个高雅的公民。因为，我们出自诗情画意的英华校园，我们不能辱没班级的荣誉，我们不能辱没校园的名声！此刻，就要从我做起，从点滴做起，在老师的引领之下，做一个言行文雅的好学生。
谢谢大家！

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.
