三分钟课前演讲稿（通用8篇）
自从伊拉克被美英联军占领以后，全世界都很震惊，住在天庭的各位古代名士也不闲着，频频召开座谈会。这不，今天又由孔子主持了一个讨论会。讨论的话题是：秦始皇建立的秦帝国为什么会灭亡。
话题一提出，坐在首席的贾谊就坐不住了，十分激动又十分自信地说：“秦亡之根本，陈涉造反也。孰不知陈涉斩木为兵，揭竿为旗，天下云集响应，赢粮而景从，于是山东诸国遂并起而亡秦族矣。由此观之，秦亡，因此子反也。”
“太傅此言差矣。”下首的杜牧胸有成竹地说，“吾读遍史诗，得到秦亡的灭因。岂不闻秦爱纷奢，然士人亦念其家，而秦取之尽锱铢，用之如泥沙。于是建阿房，修皇陵，致使天下之人不敢言而敢怨。才导致戌卒叫，函谷举，楚人一炬，可怜焦土的结局。吾之观比您深思数层，服否?”
“慢来!”未等不服气的贾谊答语，文学大师苏洵厉声喝住，然后拍着胸脯说，“公之言也未必就对。六国破灭之时，非兵不利，战不善，弊在赂秦也。赂秦而力亏，破灭之道也，因此有人说：不赂者以赂者丧。故曰：弊在赂秦。由此观之，秦在五国并存之时就懂得如何行贿、收贿。到秦统一宇内，平定八方以后，有赵高这等行贿高手，又有李斯这等收贿的高官。秦能至万世么?几千年以后的凡人陈希同、王宝森、王怀忠诸子，不也因为‘贿赂’二字而败吗?所以我认为‘贿赂’是秦灭之因。”
“非也，非也。”魏征轻轻摇着头说：“吾坚信，秦亡之因是因始皇未得吾鉴太宗十思疏。若始皇得此疏，必不会受小人蒙蔽，则会选能而任之，择善而从之，则秦国上下必会智者尽其谋，勇者竭其力，仁者播其惠，信者孝其忠，则天下就可垂拱而治，又岂能亡乎!鸣呼!
秦亡，因无治世能臣也。”(他很自信地说)
亚圣孟子问：“公乘过时间机器乎?”魏征一愕，“没有”。孟子于是微闭双目，成竹在胸地说：“吾乘时间机器到秦帝国游了一回。看见狗豕贪人食而不知检，途有饿殍而不知发，秦贵族视之竟说：非我也，岁也。鸣呼，秦国方统一四海，平定八方，未固根本。暴政施行，天皆怨，才至于亡，勿施仁政之国必灭也……”
“子勿多言!”西楚霸王项羽怒目而立，“‘胜者王，败者寇’，自然之理也，何来这么多言论。”
诸公混乱，怨怒，场面混乱。
“静一静!静一静!”孔子发言了，“诸公岂不闻苏轼有诗曰：‘横看成岭侧成峰，远近高低各不同。不识庐山真面目，只缘身在此山中。’诸公之言都是有理有据的，但大家又都太自信，只站在一个位置看问题，因此，对问题认识得不够全面，我希望大家在相信自己的同时，也听取一下别人的意见，择其善者而从之，其不善者而改之。那样，我们才能够提高自己，使我们立于不败之地。好了，会议到此为止，下回再议，望诸公都有所提高。散会!”
尊敬的老师，亲爱的同学们，大家好，下面我来讲一下我自己的故事。
那一次我尝到了成功的滋味
在一个人的一生中，有成功也有失败。也许失败占百分之九十九，而成功只占百分之一，所以说成功是难能可贵的，成功的滋味也是不同寻常的。我也成功过，也曾尝到过成功的滋味。
小时候有一次我去学游泳，以为游泳很容易，哪里知道学起来并不轻松。爷爷首先跃进了游泳池，我站在上面不敢下水。爷爷鼓励我说：不要怕，你下水来试试，不下水是学不会游泳的。
我在爷爷的鼓励下，下到了水里，可水刚刚没过胸口，便感到了水的压力。它把我肚子挤得瘪瘪的，喘气时要用很大的气力，鼻子不知干什么去了，吸气吃力，只有张大嘴巴大口呼吸，似乎要吞食什么东西，很难受。后来，我在水里学走路，我想学游泳也没什么大不了的，只要大口吸气，身体就会轻轻松松地漂起来，再刨几下，用脚划划水，就会“扬帆前航”了。可自己的腿仿佛注了铅一般，抬起来非常吃力。
首先要在水里学会憋气，整个脑袋都在水里，而且一不小心就会吃到一口水，我吗，大概可以憋二十秒，我想，我还要继续努力，向三十秒前进。然后就开始学游泳的基本功了，我的手像船浆一样从中间向四周划开，脚一上一下来回舞动着，还要憋气，刚扑腾了两三下，自我感觉还不错，有点骄傲了，这时我感到了身体在慢慢下沉。
于是，我的心一慌，手脚全乱了，接着就又喝了一口水，那滋味儿真不好受后来，爷爷帮助我，把我拉上岸来，对我说：“你的毛病就是换气、划水和蹬腿不协调的结果，只要坚持下去就能成功。”我不再气馁，坚信“铁杵也能磨成针”，我决心再次下水，一定要把游泳学会。我深深地吸了一口气，猛地一下钻入水中，接着就按照爷爷教我的要领一点点地划了起来。果然，爷爷教我的要领很有效，我坚持游了下来。在那一刻，我尝到了成功的滋味。
后来，爷爷奶奶看见我会游泳了，都夸我厉害，我自己也开始沾沾自喜了，这时爷爷要趁热打铁，赶紧教我仰泳，让我再会一种游泳的方法。当然，仰泳我也学会了。在回家的路上我一路都很开心，因为我尝到了成功的滋味了。
保护环境，珍惜水资源——让大自然里依旧能听到水流动的声音。
一则公益广告我铭记心中：一个水龙头正艰难地往外滴着水，滴水的速度越来越慢，最后终于再也滴不出水来。随后，出现一只眼睛，眼中滴下一滴泪水——如果人类不珍惜水，那么，我们看到的最后一滴水，将会是我们的眼泪!在自然界中，有许多令人流连忘返的美景，那美丽静谧的湖泊、欢快活泼的小溪、奔腾不息的江河、汹涌澎湃的大海，无一不令人心驰神往，可是那湖波、小溪、江河、大海里流着的就是那水龙头里的水，如果水龙头中的水一滴也滴不出来了那湖波、小溪、江河、大海里还会有水吗?要不就已经干涸了，要不就是所剩无几了。
水是万物之源，是自然界不可缺少的物质。有了水，才有了令人向往的美景，才有了自然界无穷无尽的能量。近年来，电视节目中经常提到水资源短缺问题：黄河的许多河段已越来越浅，陕西的渭河已见断流，山西的汾河水也早已不再奔流，而淮河、太湖等的水污染警报更是频频传来。更令人心忧的是，一些地处西部偏远地区的小山村，缺水缺到过年才能分到五斤水的地步。就说我外婆家的小河里的水也比以前浅了许多许多，童年的往事想来有趣，令人发笑，它们就像一颗颗珍珠在眼前浮现，往年，在那小河里游泳，河水到我脖子里，可是现在游泳浅的地方到我大腿，深的到我肚子。
有了水，才构成这个蔚蓝的星球;有了水，整个世界才有了生命的气息;有了水，我们的世界才变得生机盎然;有了水，我们才有了秀美的山川、清澈的溪水、湛蓝的海洋……我们才有了一切。
the first time i saw bao was in , the year when thomas and uber cup was held. at that time he was playing against li zongwei, who is also a good player from malaysia. bao beat him. to tell the truth, at first the reason why i liked him was just because i thought he was pretty.*(maybe it is not a suitable word, but i think no better word can describe him, he is really pretty!) from that time, i have focused on him. then gradually, i found that he not only has good appearance, but also has a talent for badminton.
he is very tall, about 1.90 meters. he is the tallest one among all the players in the chinese badminton team. in , he is chosen as the flag holder stands for china in the opening ceremony in the 15th asian games held in doha. it was the first time that the badminton players were chosen to take over the special task, before which time, it belonged to the basketball players. it was a great honor. and it also proved that bao was an excellent athlete. we are all proud of him.
he began to play badminton when he was at primary school. in , he won his first good medal, which was significant to him, in guangzhou. because of that, he entered the chinese badminton team. as he is as old as lin dan, who is the top one in the world, he is always put into a situation wh(。)ich is not good to him. he seldom beats lin dan, so he gained a name which is called’千年老二’. in fact, his techniques are comprehensive, but he is lack of passion, the desire to win is not so strong. so he always has misplays. due to this, he seldom wins the gold medal. i think this is related to his character. he is easygoing and couth; he looks as if he will never get angry with anybody. so this affects him while he is playing badminton. in a period of time, critical voice has come towards him. he is under great pressure. he was not in the best state. but recently he cheers up again. several days ago, the chinese badminton championship was held in guangzhou. i went to see him on saturday. i was very excited, and i shouted loudly, hoping he could hear me. there is no doubt that he won the game. before he went away, he waved hand to us, how excited i was at that time! the next day, he beat li zongwei again and he won the man’s single gold medal. all of us are very happy. after 7 years, which could be a long time for an athlete, he proved himself again in guangzhou, which is considered as his lucky place.
i think this will be the energy of his advancing. and i hope he can keep this fighting will and win the gold medal in the 29th olympic games held in beijing!
best wishes!

同学们，老师们，早上好!
今天是20xx年3月30日星期一，是第X个全国中小学生安全教育日，今年的主题是“我安全，我健康，我快乐”。请同学们跟我一起说一遍主题——我安全，我健康，我快乐。同学们，教育部高度重视中小学生的安全工作，为此教育部还颁布了《关于做好20xx年中小学生安全工作的通知》，上周每位同学还收到了《致全国中小学生家长一封信》，其目的就是家校携手一起做好安全工作，加强同学们的安全意识和自我保护意识，提高大家避险防灾和自救能力，严防意外事故的发生。信中尤其提到了“六不”，希望同学们在家里与爸爸妈妈一起认识学习，牢记在心。为了配合安全教育日活动，湖南卫视《新闻大求真》栏目于3月31日18︰00-18︰30将播出教育部委托湖南卫视策划制作的以中小学安全教育为主题的节目，请每位学生，在家与父母共同观看，学生发展中心会发短信通知你们的父母。中高年级同学可以写一写感后感，到时各班选出一部分优秀作品在班级展板展出，一部分将在学校大厅展示。
此外，大家要认真上好每周三的晨会，班主任老师会在晨会上结合学校布置的每周学生常规要求学习相关的安全知识，也会带着大家登陆“安全教育平台”进行学习。大家要积极完成作业，让安全知识为生命护航。
同学们，和谐校园，安全第一。也许就在课间，你和同学打打闹闹没有注意，安全事故就发生了;也许就在走廊上、拐弯处，你奔跑时，冷不丁对面也冲出一个同学，安全事故就发生了;也许就在放学后做值日时，你和同学举着扫帚挥舞着，安全事故就发生了……其实很多时候，这些事故都可以避免。规范好自己的行为，就是对自己负责任。对自己负责任，才能对他人负责任，才能有一个和谐、文明的校园。
最后，请同学们再跟我一起说一遍今年安全教育日的主题——我安全，我健康，我快乐。谢谢!祝同学们快快乐乐上学，平平安安回家!我的讲话到此结束。
学习，是被子，是让人安适的;学习，是开心果，是让人快乐的;学习，是午餐，是让人享受的。享受学习的感觉是难以得到的，但只要你努力了，就可以享受的到。
学习的享受多姿多彩。学习是知识的来源，也是做人的根本。在生活中处处都有学习，人们在蝴蝶身上获得启示，制造了飞机。人们在人手的结构中得到了启示，发明了挖掘机。世界真是无奇不有，看来，知识能给人们带来便利。
长大了，也处处需学习。长大以后，找工作都要有高学历，没有学习就没有知识，没有知识就没有高学历，没有高学历就更没有工作了。如果不学习，就很难找工作，就算找到了，也挣不了什么钱。再看来，学习还能带来财富啊!
在中学的学习过程中，不应感到痛苦，因为学习能给我们带来无穷的知识。在求知的过程中，会遇到各种各样的困难，但闯过了困难，最后就会享受到学习的快乐。
学习会带来快乐，学习会带来便利，学习会带来财富，难道学习不是一种享受吗?
Good morning,dear teacher and my friends.
It’s a very intresting topic today.
I think my dad was a hero for me when i was a young child. we'd go fishing, walks, and other fun things for a kid.
Every child has a good and great father, and so do i. my dad played a very important role in my daily life——exactly speaking, in my past 16 years.
My father always stands in the center of my life， from past till now and possibly in the future.
My family was rather poor when i was in my childhood. we didn't have our own house and had to live in a shabby， small room rented from my father's factory. the room was so small that there was little space for people to walk. i didn't have my own bed and had to sleep with my parents. this is terrible both for my parents and me.
But father made this all different!he works very hard on his own business, now we have our own 2 housese,surly,i have my own room.and he take our family so much happiness, richer and richer.
When i was little, i did everything with my dad. you could always find me sitting on his knee or walking and doing everything with him. every night he would read me a bed time story and make the voices of each character.
I learnt a lot from my daddy. i learnt to never take things to seriously and to always smile.
Like many other fathers, my dad and i also has generation gap. he is not good at or even can’t work the computer. so when i sitting at the computer desk,he will say something like ‘you should pay more attention to your study’， ‘don’t waste time on the computer games’ , ‘it will be bad for your eyes’ and so on. how can i- a computer fan – reduce time on computer? so i continue studying and playing on it
Years pasted, my father is over 45 now. it is time for me to look after him and i am sure i will do and we will live an even better life. and i will say,i really love you dad,cause you are the hero in my mind.
Thank you so much!
