全文共 739 字
+ 加入清单现实中,青少年吸毒已成为一个触目惊心的严重问题。来自国家禁毒委员会办公室的数字表明,我国最近几年青少年吸毒的比例始终在吸毒人口中占80%左右。据不完全统计,16岁以下的少年吸毒人数有所增加,青少年已成为最易受到毒品侵害的“高危人群”。
目前,学校毒品预防教育工作在认识上还存在着一些误区:一是怕学生知道毒品。认为禁毒教育会引发学生的好奇心,促使他们冒险尝试;二是认为禁毒教育是公安部门的事,与学校无关。这些认识误区的一个前提,就是目前在校学生吸毒者罕见。事实上,毒品蔓延的速度相当快,若等到毒品在校园时再来教育,则为时已晚。由此可见加强禁毒教育,做好超前预防工作,是解决青少年吸毒问题的根本途径和出路。
自1997年国家教委规定把禁毒教育作为国民素质教育的组成部分,并正式纳入中小学德育教育教学大纲以来,六年来我校通过“家长学校”、“心理健康教育课”、“青春期专题讲座”、“青年志愿者宣传队”、赴禁毒教育基地参观等多条渠道对家长、学生、社区居民广泛开展了“珍爱生命,远离毒品”、“不让毒品进我家”等宣传教育活动,还组织教师面向市、区专家开了一节“美丽的罂粟花”心理健康教育公开课。学校对学生毒品预防教育的有效性得到家长、社区及区有关部门的高度评价。
学校优良的校风带动着周边小区的精神文明建设,对所在社区的精神文明建设水平的提升具有明显推动作用。学校2001、2002年连续两次评为“石泉社区教育先进学校”、2002年被授予“创精神文明特殊贡献奖”。
至于如何搞好学校禁毒教育,还有待于大家在具体实践中进一步探索,但有一点必须肯定,目前毒品虽尚未在学校出现,但“防患于未然”总比“亡羊补牢”为好。加强毒品预防教育仍然是学校德育工作一个方面,今后学校将从以下几方面开展禁毒工作的实践探索。

篇1:教师党员不忘初心继续前进演讲稿
全文共 1111 字
+ 加入清单把握“八个坚持”高扬理想信念旗帜
学习好、贯彻好习近平总书记“七一”重要讲话精神,最重要的就是深刻领会、认真落实“八个坚持”的精髓要义和实践要求。连日来,哲学社会科学界广泛开展学习习近平总书记重要讲话的活动,研讨交流学习心得体会。7月2日,在武汉大学举行的“学习习近平总书记‘七一’讲话 纪念中国共产党成立95周年学术研讨会”上,全国哲学社会科学规划领导小组副组长、湖北省人大常委会副主任尹汉宁表示,把握好“不忘初心、继续前进”这条主线,有利于深刻领会讲话的高远立意和深刻内涵。尹汉宁认为,“不忘初心、继续前进”,体现了马克思主义的历史观和实践观;体现了理论上的清醒和政治上的坚定;体现了对历史经验与历史规律的深刻把握;体现了足够的底气和自信;体现了崇高的使命意识和责任担当。
“强调‘不忘初心、继续前进’,具有重要的理论思想意义和现实行动意义,不应误认为马克思主义和共产主义理想过时了,而抛弃正确的主义和崇高的理想,要在充分的道路、理论、制度和文化自信自觉基础上,保持建党初心,继续推动马克思主义及其中国化理论与实践的发展,以实际行动积极推进‘五位一体’总体布局,协调推进‘四个全面’战略布局,早日实现‘两个一百年’的宏伟蓝图。”程恩富表示。
“这是坚持和发展中国特色社会主义、实现中华民族伟大复兴的顶层设计。”陈金龙表示,马克思主义指导、共产主义与社会主义理想、全心全意为人民服务可谓“初心”;“四个自信”是“继续前进”的精神力量;全面建成小康社会是“继续前进”的近期目标;全面深化改革是“继续前进”的具体路径;人民主体是“继续前进”的依靠力量;走和平发展道路、保持党的先进性和纯洁性是“继续前进”的重要保障。“八个坚持”是以习近平同志为总书记的党中央治国理政新理念新思想新战略的进一步总结和概括。
对中国道路的开拓和发展,国内外有一些不同的声音,我们不能被杂音所影响,要“不忘初心、继续前进”。对学界而言,谢春涛认为,就是要用历史的眼光、发展的眼光理解中国道路,从改进自身工作、提高讲中国故事的水平、提高研究能力、加快构建中国特色哲学社会科学等方面,去努力阐释好中国道路。
“这场考试还没有结束,还在继续”
习近平总书记强调,1949年3月23日上午,党中央从西柏坡动身前往北京时,毛泽东同志说:“今天是进京赶考的日子。”60多年的实践证明,我们党在这场历史性考试中取得了优异成绩。同时,这场考试还没有结束,还在继续。全党同志一定要不忘初心、继续前进,永远保持谦虚、谨慎、不骄、不躁的作风,永远保持艰苦奋斗的作风,勇于变革、勇于创新,永不僵化、永不停滞,继续在这场历史性考试中经受考验,努力向历史、向人民交出新的更加优异的答卷!
篇2:大学生英语演讲稿:Change--改变
全文共 2111 字
+ 加入清单Leo Tolstoy once said, everyone thinks of changing the world, but no one thinks of changing himself.
He is right. We always have great plans and dreams in our minds… too ready to achieve something grand thatChanges the world or benefits all of mankind .For example; we hate pollution and have made up our minds to find new energy sources that keep the environment clean. Yet we still litter on the ground. We complain about traffic jams, so we plan to build more highways to solve the problem, but it never occurs to us that our failure to follow traffic regulations is the leading cause of this situation. We are so concerned that the violence in the media has a bad impact on our children, we urge the government to set laws to protect them. But, do we, as adults, set a good example for our kids? We use nasty words and even spit on the ground in front of them, I dare to say, we harm more!
In my opinion, before we decide to change the world, we had better change ourselves first. As ordinary individuals, we do not have the power to change the world. But we can change our habit of littering, spitting, cussing, we can respect the environment around us, we must act as good models for our kids.
If each of us does all of these little things, all of us, millions and millions of individuals together, together we will be strong …strong enough to change our world!
So please, the next time you do something, think how your actions influence not only you, but those around you too, especially our children …and perhaps more importantly…our planet!
列夫·托尔斯泰曾说过:每个人都想改变这个世界,但是没有人想到改变自己。
他说的很有道理,我们每个人都心怀伟大时志向,时刻准备去干一番能造福全人类的大事业。比如,我们痛恨环境污染,所以我们下定决心去开发新的更高效更干净的能源来保护我们的环境,但是同时我们却随手乱扔垃圾;我们抱怨大城市的交通堵塞,计划造更多的高速路来解决交通问题,但是我们从来没有想过,如果我们能遵守交通规则话,那么这一问题是不是可以得到很大得缓解呢?我们担心电视电影里面得暴力会对我们得孩子产生不良的影响,于是我们敦促政府通过立法来保护未成年人,但是我们这些大人又做得怎么样呢?我们为我们的下一代做好了表率吗?我们说粗话,甚至在孩子面前抽烟。不客气地说,我们对孩子的不良影响更多!
在我看来,在我们打算改变这个世界之前,我们最好先改变一下自己。作为一个普通人,我们其实没有改变这个世界的能力,但是我可以改变我们随地扔垃圾,随地吐痰的坏习惯, 我们应该学会去保护环境,我们应该为我们的孩子起好的表率作用。
如果我们每个人都能从小事起,那么千千万万个人力量汇聚在一起,那力量是强大的,足以改变这个世界。
朋友,当您在做某一件事情的时候,请您想一想,您的行为会对您周围的人产生怎样的影响, 因为,您的行为不单单影响到您自己,还有您周围的人,更重要的是我们的孩子…甚至我们的世界。

大家好!
母亲的爱比天还要广阔比海还要深。母亲赐予我们宝贵的生命,是她用爱的力量渲染我们,感动我们。正是这种力量,让母爱成为了最伟大的爱。
有人说,孩子都是来向父母讨债的,父母有了我们以后,省吃俭用,总是把最好的吃的、用的,最贴心的爱,甚至连自己的宝贵的生命都给予了我们。而我们呢,有的时候父母总是对我们唠唠叨叨的,这种“唠叨的爱”,我们却把它视为一种恨。可我们有曾想过吗?父母对我们的良苦用心我们有理解过他们吗?不但有时没理解还责怪他们。其实父母的每个动作,每句话都是他们发自内心对我们的爱,我们应该珍惜这种来之不易的爱,要把这种爱保存在心里。
今天就是个特殊的日子,是全天下母亲的节日,是我们报答父母的节日,是他们让我们过上了幸福生活。我知道他们的爱仅仅用三言两语是表达不出来的,那就让母爱保存在心里吧,化作美好的回忆。今天,让我们对自己的父母大声说出藏在心底的话:“爸爸,妈妈我爱你们!”让我们共同庆祝这特殊的节日吧!
祝:全天下父母节日快乐!你们辛苦了!

曾几何时,祖国您历尽磨难,饱受沧桑。侵略者的魔爪,将您瓜分,冒险家的肆虐,将您洗净。您每一寸土地都被烙上深深的血痕,您每一张容颜都布满了惊恐!山河在呜咽,松涛在哀鸣。然而英雄的中国人并没有趴下,一片片忠心,一首首悲歌,化作那一声声呐喊,一股股豪情!为挽救我沉沦的祖国,多少仁人志士上下求索,多少英雄豪杰血染疆场。南湖的红船吹响了革命的号角,井冈山的红旗点燃起星星之火。沉睡的雄狮终于发出震耳欲聋的怒吼,东方巨龙终于抖擞精神扬威于世!1949年10月1日,天安门城楼上那气壮山河的呐喊,展示了中国人的气魄和胆量,挺起了一直佝偻着的中国人的背梁。
回首过去,我们雄心激荡;展望未来,我们豪情万丈!
建国六十年,祖国的变化日新月异;沧桑岁月虽留痕,繁荣盛事正展现。胸怀祖国,放眼世界,我的眼里充盈着激动和兴奋的泪花,我常常心中深情地呼喊“祖国,您是我心中最美丽的花”!我深深地把您热爱。

近三十年的改革开放,我们的祖国又驶上了发展的快车道;从唱响“春天的故事”到“神七”载人飞船的升空,从“东亚病夫”到奥运会成功举办……一切的一切,无不展示我中国人的勤劳、坚强、智慧和勇敢。
泱泱大中华,悠悠五千年。每一次五星红旗冉冉升起,每一次国歌在我耳边响起,我都会为自己是中国人而自豪,骄傲。
同学们,“少年强,则国强;少年富,则国富,少年屹立于世界,则国屹立于世界!”我们是祖国的骄子,是新时代的宠儿。祖国人民对我们充满期盼,时代赋予我们振兴的责任,让我们行动起来,点燃心中那团火焰,为实现我们中华民族的伟大复兴而努力学习吧!
篇6:——李嘉诚汕头大学“柠檬汁人生观”励志演讲
全文共 1032 字
+ 加入清单人生的过程中尽管不无遗憾,但我学到最价值连城的一课——逆境和挑战只要能激发起生命的力度,我们的成就是可以超乎自己所想像的。
我成长的年代,香港社会艰苦,是残酷而悲凉的。那时候没有什么社会安全网,饥饿与疾病的恐惧是强烈迫人。求学的机会不是每一个人的权利,贫穷常常像一种无期徒刑。今天社会前行,新的富足为大部分人带来相对的缓冲保障,贫穷不一定是缺乏金钱,而是对希望及机遇憧憬破灭的挫败感。很多人害怕可上升的空间越来越窄,一辈子也无法冲破匮乏与弱势的局限。我理解这些恐惧,因我曾经一一身受。没有人愿意贫穷,但出路在哪里?
七十年前这问题每一个晚上都在我心头,当年十四岁时已需要照顾一家人,没有接受教育的机会,没有可以依靠的人脉网路,我很怀疑只凭刻苦耐劳,和一股毅力,是否足以让我渡过难关?我们一家人的命运是否早已注定?纵使我能餬口存活,但我有否出人头地的一天?
我迅速发现没有什么必然的成功方程式,首要专注的是,把能掌控的因素区分出来。若果成功是我的目标,驾驭一些我能力内可控制的事情是扭转逆境十分重要的关键。我要认清楚什么是贫穷的枷锁—我一定要有摆脱疾病、愚昧、依赖和惰性的方法。
比方说,当我发觉染上肺结核病,在全无医疗照顾之下,我便下定决心,对饮食只求营养不求喜恶、适当地运动及注重整洁卫生,扞卫健康和活力。此外,我要拒绝愚昧,要持恒地终身追求知识,经常保持好奇心和紧贴时势增长智慧,避免不学无术。在过去七十多年,虽然我每天工作十二小时,下班后我必定学习,告诉你们一个秘密,在过去一年,我费很大的力气,努力理解进化论演算法里错综复杂的道理,因为我希望了解人工智慧的发展,以及它对未来的意义。
无论在言谈、许诺及设定目标各方面,我都慎思和严守纪律,一定不能给人嚣惰脆弱和倚赖的印象。这个思维模式不但是对成就的投资,更可建立诚信;你的魅力,表现在你的自律、克己和谦逊中。
所有这些元素连接在一起功效非凡:它能渐渐凝聚与塑造一个成功基础,帮助你应付控制范畴以外的环境。当机遇一现,你已整装待发,有本领和勇气踏上前路。纵使没有人能告诉你前路是什么一道风景,生命长河将流往何方,然而,在这过程中,你会领悟到邱吉尔多年的名言:“只要克服困难就是赢得机会。一点点的态度,但却能造成大大的改变。”
生命抛来一颗柠檬,你是可以把它转榨为柠檬汁的人。要描绘自己独特的心灵地图,你才可发现热爱生命的你、有思维、有能力、有承担,建立自我的你;有原则、有理想,追求无我的你。

你们好!
今天我演讲的题目是《祖国在我心中》。不管是滔滔的江河、滚滚的河流、陡峭的悬崖、一望无际的草原、荒凉的戈壁滩、还是寸草不生的沙漠,都属于我们最亲最伟大的祖国母亲。
不管是古代还是现代,都涌现出许许多多的英雄豪杰。“人生自古谁无死,留取丹心照汗青。”这正是文天祥在监狱里所写的。“王师北定中原日,家祭无忘告乃翁。”这是陆游在临死前写的是,可见他在死前都一心想着国家统一。詹天佑不怕困难,也不怕嘲笑,毅然接受了任务。钱学森放弃名誉和金钱,一听说祖国成立了,就马上奔向祖国的怀抱
我们的祖国是一位美丽的妇人,却在百年以前遭受屈辱:1860年,漂亮并且被誉为艺术宝库的圆明园,竟被八国联军洗劫一空。圆明园在大火中毁于一旦,被人们称作华夏文明的瑰宝,就这样没了。9月18日,日本向中国的东北三省发起攻击,仅四个月内,东北三省就被占领。许许多多的中华儿女成为了亡国奴,就在之一时刻许许多多的爱国志士为了给子孙后代留下一个美好的未来,献出了自己宝贵的生命。同学们,不要忘了我们脖子上的红领巾是众多革命烈士的鲜血染成的。
如今,祖国的未来就掌握在我们手中。“少年强,则国强。”这句话说得一点也没错。不要忘记祖国给予我们的厚望,好好学习,天天向上,成为祖国的栋梁之才吧。因为祖国在我、在我们心中。
我的演讲完毕。
谢谢大家。

+ 加入清单读书人都爱书。自古以来,不少名人将自己勤奋读书的情趣写成对联,用以自勉或互勉。
宋代学者刘载好学不倦,知识渊博,他的书斋配挂一副自书对联:“夜眠人静后,早起鸟鸣先”,说明学习的勤奋和刻苦。
苏东坡年轻时自以为已无书不读,便书一联:“识遍天下字,读尽人间书”。 后经一老翁指点,改成:“发奋识遍天下字,立志读尽人间书”。
诗人陆游以书为伴,将书斋取名“书巢”, 并自题一联:“万卷古今消永日,一窗昏晓送流年”。
民族英雄郑成功酷爱读书,他的自勉读书联寓意深刻,颇有韵味:“养心莫若寡欲,至乐无如读书”。
清代一些读书对联各道志趣,清新可读。咸丰年间学者王文韶手书一联:“好山水游,其人多寿;有诗书气,生子必才”。
学者孙星衍写有一副对联:“莫放春秋佳日过,最难风雨故人来”。曾有不少人书写此联,张贴于书房,以鞭策自己。
文学家王士祯爱好读书写作,曾自题书斋联:“书搜万卷,读书求实用;笔剩一枝,下笔尚真情”。
《四库全书》的总纂纪晓岚写有一副对联:“浮沉宦海为鸥鸟;生死书丛似蠹鱼”。联中把自己比喻成“蛀书虫”,热爱读书由此可见。
现代名人的读书对联独具情趣。蔡元培步入仕途仍不忘读书,曾撰写对联悬于书斋:“都无作官意;惟有读书声”。
沈钧儒的书斋也有一联:“立志俯存千载想;闲淡无过五分钟”。他立戒清淡,惜时如金。
鲁迅在北京“老虎尾巴”书房西壁挂有一副集屈原《离骚》句联:“望崦嵫而勿迫;恐鹈鸟之先鸣”。他在《彷徨》的题词也引了《离骚》中的“路漫漫其修远兮,吾将上下而求索”, 正好是这一联的注脚。
周恩来读中学时,撰写一联:“与有肝胆人共事,从无字句处读书”。把如何交友,怎样读书说得明朗透彻。
毛泽东在湖南第一师范学习期间,曾写一联:“贵有恒,何必三更起五更眠;最无益,只怕一日曝十日寒”。把读书要持之以恒、循序渐进的道理说得透彻明了。
历史学家范文澜在自己书斋中悬有一联,用以自勉:“板凳要坐十年冷;文章不写一句空”。
高雅美妙的读书对联不胜枚举,常被人们引用的一副:“书山有路勤为径,学海无涯苦作舟”,出自20世纪30年代《大公报》一个年轻编辑王芸生之手。
当代作家柯灵,从小爱好读书,他的书房也挂一副趣联:“读书心细丝抽茧;练句功深石补天”。
面词义:书山有路,但是只有在书海中勤快的奔波的人,才是真正的找到路,不然就一点也学不到。学海中没有边,只有用自己辛勤劳动用辛苦作舟才能达到彼岸。
意思:读书治学要勤奋。
篇9:毕业演讲稿
全文共 7451 字
+ 加入清单Faculty, family, friends, and fellow graduates, good evening.
I am honored to address you tonight. On behalf of the graduating masters and doctoral students of Washington Universitys School of Engineering and Applied Science, I would like to thank all the parents, spouses, families, and friends who encouraged and supported us as we worked towards our graduate degrees. I would especially like to thank my own family, eight members of which are in the audience today. I would also like to thank all of the department secretaries and other engineering school staff members who always seemed to be there when confused graduate students needed help. And finally I would like to thank the Washington University faculty members who served as our instructors, mentors, and friends.
As I think back on the seven-and-a-half years I spent at Washington University, my mind is filled with memories, happy, sad, frustrating, and even humorous.
Tonight I would like to share with you some of the memories that I take with me as I leave Washington University.
I take with me the memory of my office on the fourth floor of Lopata Hall - the room at the end of the hallway that was too hot in summer, too cold in winter, and always too far away from the womens restroom. The window was my offices best feature. Were it not for the physics building across the way, it would have afforded me a clear view of the arch. But instead I got a view of the roof of the physics building. I also had a view of one corner of the roof of Urbauer Hall, which seemed to be a favorite perch for various species of birds who alternately won perching rights for several weeks at a time. And I had a nice view of the physics courtyard, noteworthy as a good place for watching people run their dogs. Its amazing how fascinating these views became the longer I worked on my dissertation. But my favorite view was of a nearby oak tree. From my fourth-floor vantage point I had a rather intimate view of the tree and the various birds and squirrels that inhabit it. Occasionally a bird would land on my window sill, which usually had the effect of startling both of us.
I take with me the memory of two young professors who passed away while I was a graduate student. Anne Johnstone, the only female professor from whom I took a course in the engineering school, and Bob Durr, a political science professor and a member of my dissertation committee, both lost brave battles with cancer. I remember them fondly.
I take with me the memory of failing the first exam in one of the first engineering courses I took as an undergraduate. I remember thinking the course was just too hard for me and that I would never be able to pass it. So I went to talk to the professor, ready to drop the class. And he told me not to give up, he told me I could succeed in his class. For reasons that seemed completely ludicrous at the time, he said he had faith in me. And after that my grades in the class slowly improved, and I ended the semester with an A on the final exam. I remember how motivational it was to know that someone believed in me.
I take with me memories of the midwestern friendliness that so surprised me when I arrived in St. Louis 8 years ago. Since moving to New Jersey, I am sad to say, nobody has asked me where I went to high school.
I take with me the memory of the short-lived computer science graduate student social committee lunches. The idea was that groups of CS grad students were supposed to take turns cooking a monthly lunch. But after one grad student prepared a pot of chicken that poisoned almost the entire CS grad student population and one unlucky faculty member in one fell swoop, there wasnt much enthusiasm for having more lunches.
I take with me the memory of a more successful graduate student effort, the establishment of the Association of Graduate Engineering Students, known as AGES. Started by a handful of engineering graduate students because we needed a way to elect representatives to a campus-wide graduate student government, AGES soon grew into an organization that now sponsors a wide variety of activities and has been instrumental in addressing a number of engineering graduate student concerns.
I take with me the memory of an Engineering and Policy department that once had flourishing programs for full-time undergraduate, masters, and doctoral students.
I take with me memories of the 1992 U.S. Presidential debate. Eager to get involved in all the excitement I volunteered to help wherever needed. I remember spending several days in the makeshift debate HQ giving out-of-town reporters directions to the athletic complex. I remember being thrilled to get assigned the job of collecting film from the photographers in the debate hall during the debate. And I remember the disappointment of drawing the shortest straw among the student volunteers and being the one who had to take the film out of the debate hall and down to the dark room five minutes into the debate - with no chance to re-enter the debate hall after I left.
I take with me memories of university holidays which never seemed to apply to graduate students. I remember spending many a fall break and Presidents Day holiday with my fellow grad students in all day meetings brought to us by the computer science department.
I take with me memories of exams that seemed designed more to test endurance and perseverance than mastery of the subject matter. I managed to escape taking any classes that featured infamous 24-hour-take-home exams, but remember the suffering of my less fortunate colleagues. And what doctoral student could forget the pain and suffering one must endure to survive the qualifying exams?
I take with me the memory of the seven-minute rule, which always seemed to be an acceptable excuse for being ten minutes late for anything on campus, but which doesnt seem to apply anywhere else I go.
I take with me the memory of Friday afternoon ACM happy hours, known not for kegs of beer, but rather bowls of rainbow sherbet punch. Over the several years that I attended these happy hours they enjoyed varying degrees of popularity, often proportional to the quality and quantity of the accompanying refreshments - but there was always the rainbow sherbert punch.
I take with me memories of purple parking permits, the West Campus shuttle, checking my pendaflex, over-due library books, trying to print from cec, lunches on Delmar, friends who slept in their offices, miniature golf in Lopata Hall, The Greenway Talk, division III basketball, and trying to convince Dean Russel that yet another engineering school rule should be changed.
Finally, I would like to conclude, not with a memory, but with some advice. What would a graduation speech be without a little advice, right? Anyway, this advice comes in the form of a verse delivered to the 1977 graduating class of Lake Forest College by Theodore Seuss Geisel, better known to the world as Dr. Seuss - Heres how it goes:
My uncle ordered popovers
from the restaurants bill of fare.
And when they were served,
he regarded them
with a penetrating stare . . .
Then he spoke great Words of Wisdom
as he sat there on that chair:
"To eat these things,"
said my uncle,
"you must excercise great care.
You may swallow down whats solid . . .
BUT . . .
you must spit out the air!"
And . . .
as you partake of the worlds bill of fare,
thats darned good advice to follow.
Do a lot of spitting out the hot air.
And be careful what you swallow.
Thank you.

人的生命是最宝贵的,只有有了生命才能创造财富,才能使世界变得更美好。只有同学们的欢声笑语、活泼身影,才能使我们的校园充满阳光,充满生机。但是人的生命又是非常脆弱的,如果我们不重视安全,视安全隐患而不顾,对安全问题措施不及,防范不严,责任心不强,把生命当儿戏,那么造成的后果不堪设想。交通事故猛如虎狼,我们身边随时都潜伏着张牙舞爪的杀手,随时都威胁着你的生命安全。一件件,一桩桩血腥的报道,令人胆战心惊,一幕幕惨剧目不忍睹。只因为忽视了安全问题,一个个生命如鲜花在瞬间凋零,后果带给社会、家庭、亲人只是悲痛欲绝的伤心,沉重的打击,血的教训。到那时,这一切都为时已晚,我们失去的已经太多太多,对生命的关爱,不能成为美丽的词藻,难道只有失去之后才能醒悟?由于安全意识的淡薄,难道我们不该反思吗?而我们今后应该怎么做,更令人深思。
记得有一个故事。几个学者与一个老者同船共渡。学者们问老者是否懂得什么是哲学,老者连连摇头。学者们纷纷叹息:那你已经失去了一半的生命。这时一个巨浪打来,小船被掀翻了,老者问:“你们会不会游泳啊?”学者们异口同声地说不会。老者叹口气说:“那你们就失去了全部的生命。”
虽然这只是一个故事,但其中蕴含的哲理却耐人寻味。灾难的发生对每个人来说,不分贫富贵贱,不论性别年龄。无论咿呀学语,还是学富五车,无论幼小纤弱,还是身强力壮,如果缺少应有的警惕,不懂起码的安全常识,那么,危险一旦降临,本可能逃离的厄运,却都会在意料之外、客观之中发生了。尤其是我们这些自我保护能力弱的小学生,更应该从小做起,从自我做起,树立良好的交通安全意识,养成良好的安全习惯,才能远离交通安全事故,保障家庭的幸福和社会的和谐。
遵章守纪,就是尊重生命,尊重自我。当我们能做到这一切的时候,我们的社会便向文明的彼岸又靠近了一步。重视交通安全,是我们每个人的义务,更是我们每个人的责任。让我们携起手来呵护这文明之花,让我们远离伤痛,珍爱彼此的生命吧。
篇11:小学生演讲稿450字:健康与安全,从我做起
全文共 457 字
+ 加入清单以下为大家提供一篇小学生演讲稿--健康与安全,从我做起,仅供参考。
不知哪位名人说过:“健康是‘1’,健康以外的所有东西是‘1’后面的‘0’。如果‘1’没有了,那么所有的‘0’也就没有意义。”
看来健康是何等重要。我以前身体一直不太好,感冒、咳嗽经常发生。于是在爸爸鼓励下,我开始做运动了,早上起来跑步,课余时间踢毽、跳绳。结果这些毛病很少出现了。从中我可以体会到做运动的好处。同学们让我们手拉手,一起来做运动。让我们拥有一个健康的身体。
安全是健康的“兄弟”。谈到安全,我想起了暑假里播出一条新闻,两个苏州小朋友他们来到一条既宽又深,而且没人看守的池塘游泳,由于他们的水性不太好,结果溺水身亡。我真为他们感到惋惜。
最近在我们常熟凯莱鞋都发生了一场特大火灾。虽然消防人员全力扑救,但是大火还是烧了近一夜的时间,把一幢六层楼给全部烧毁了。损失惨重,令人痛心疾首。
我想人们对安全不太重视引起的吧。让我们携手起来,并且让我们的父母学习安全知识,让悲剧不再重演。
安全、健康是“兄弟”,只要我们积极锻炼,重视安全,幸福就会在身边。
篇12:我有一个梦想演讲稿
全文共 733 字
+ 加入清单每个人都有梦想,它是人人所向往的。没有梦想的人的人生将是空虚的,人生没有梦想就如飞机失去航标,船只失去灯塔,终将被社会所淘汰。但梦想总是随着思想的前进而改变的。碌碌无为是庸人所为,奋发图强是智者之举。
童年时,我有一个梦想,我希望我有钱。大人问:“小伙子,有了钱你要去干什么呢?”“我要去买泡泡糖”“如果你有很多钱呢?”“我会去买很多泡泡糖”“如果你有用不完的钱呢?”“我会把做泡泡糖的工厂买下来。”的确小时侯的我们,天真无邪,有着一颗善良的童心,幸福与快乐是一曲不变的乐章。
慢慢步入小学,中学……就越会觉得压力的存在。现在我有一个梦想。我希望每天都不要有很多的家庭作业要做。玩耍的时间一点点被剥夺,而我们一天中40%被禁锢在教室,很多时间在学习。但是面对学习,还是一种模糊的认识。俗话说“难得糊涂”,对事物的理解,也由封建主义发展到资本主义,越大就越觉得自己的观点是对的。
上初中的时候,我有一个梦想,我希望自己能成为一名尖子生;回到家能受到家人的表扬;在学校能受到老师们的肯定;在同学之间能有鹤立鸡群的表现。但是,渐渐的,我发现实现这个梦想并不能靠要耍耍孩子气。之后,我学会了奋斗。
忙忙碌碌一天加上晚自习后放学回家,真是又困又累,吃夜宵都没有味道。这样的日子很单调,也许有时候想念许多小学同学,有时候赶着上课还是一双朦胧的睡眼。讨厌死板的校服装,从不穿着它到处走。星期六、星期天的时间真很短,孩子脾气真想犯,慢慢懂了做人的辛苦和梦想真是太难,还好我会努力,看每一个人都在为了生活而起早赶晚,把握自己不再松散。
今天,我有一个梦想,我希望自己能考上一所中意的高中。我为着梦想,`每一天都苦苦寻找着充实自己的辅导书与练习卷,为着光明的未来而努力。
谢谢大家,我的演讲结束了。

篇15:听邹越老师演讲《让世界充满爱》观后感
全文共 972 字
+ 加入清单感恩是一种生活态度。从前我一直不这样认为,我觉得所有的一切应该是命中注定或上苍所赐,我和所有男男女女一样,多了一颗抱怨的心。
但从我看过教育演讲后,一切恰恰相反,当我被邹老师那发自内心的呼唤,唤醒了我沉睡的心灵。让我对生活有了许多感触,邹老师她的演讲太精辟了,每时每刻都拨动着我们的心弦给我们灌输思想教育,使我得受感动。因为她让我懂得感恩的真谛。
在人类的精神天空中,感恩不是飘忽而逝的云彩,而是云彩背后一片洁净的湛蓝。感恩在人类精神的坐标中,不是偶然,而是永恒。感恩的行为是自然的,它是一种无意识,向须臾不停的呼吸,伴随在生命的韵律之间。人类的美是以爱来呈现的,而感恩之心是人类心田中最美的种子,它发芽之后,开出爱之花,结出爱之果。我觉得经历了这种沧海桑田的人一定寡言、少语,或者喜欢独处沉默。不懂得感恩的人不知道幸福的滋味。不化妆的微笑更纯洁而美好,不化妆的目光更坦率而真诚,不化妆的女人更有勇气面对人生。
感恩节是美国一个折不扣地最地道的国定假日。这一天,具有各种信仰和各种背景的美国人,共同为他们一年来所受到上苍的恩典表示感谢,虔诚的祈求上帝继续赐福。
可是,大多时候,我们缺少了一个感恩的心!
是的,感恩是生活中的大智慧。有了感恩的心,一花,一草、一木、一树,一嗔笑、一落泪、一心算、一动情……人世间,看花倾城,那红尘中小小的善和好,足以打动冷漠的心。常怀感恩的心,便不多言回报,只问耕耘,感谢上苍给你这么鲜活的生命,慈爱的父母,手心手背的兄弟,纯粹的爱,美好的生活……这生活中的感恩,多一份付出,便多了一份欣喜。
感恩之心是我们能够知道生活中的甜与苦;感恩之心又足以使稀释我们心中曾经的积怨和愤恨,并且让它慢慢云淡风轻;感恩之心还让我们在自己宁静的世界里,不以物喜,不以己忧,用干净的眼神看得世界,用纯粹的心灵面对生活,用一个颗感恩的心去贴近生活,用我们丰富的内心之火,去调和生活调色板中的色彩。这样,生活的色彩才不会凝固,才是流动的,鲜活的,跳跃的,而我和你,才会活得如此禅意,如此芬芳。
拥有感恩的心,会看到生活细微处的美妙和动人,会听到风在空气里流动的音乐,会等待春天的到来,会期盼着一个约定;会思念远方的朋友,会在突然的霎那就轻轻笑了,因为,你懂得,生活原本十分美妙,而感恩,使一件幸福的事。
懂得感恩的人是幸福的人,成功的人,受欢迎的人。
篇16:中学生行为规范演讲稿1000字
全文共 991 字
+ 加入清单各位老师、各位同学,我是初二x班的xxx。新的一学期开始了,新的征途中,我们肩负着许多责任,中学是我们学习知识、增长见识、历练意志、培养情操、健全人格的重要时期,所以更加要注意自己的行为规范。纪律和规则是我们平时工作、学习和生活中不可缺少的。很多事实都能说明这个道理,比如买票要排队;走在马路上要遵守交通规则;甚至我们平时的一举一动都受到一定的要求和约束,否则任何事情都毫无秩序可言。而我们作为学生,更是有数不清的纪律和规则来要求我们,告诉我们该怎么做不该做什么。但是,如果我们总在一种被要求的环境下学习和生活是很难进步的,所以我们应该学会自己约束自己,自己要求自己,变被动为主动,自觉地遵守中学生日常行为规范,拿它来约束自己的一言一行。
作为初中生的我,自觉遵守中学生日常行为规范,为人真诚、坦率,诚实守信,礼貌待人,热爱集体,同学之间团结互助,遵规守纪,讲普通话,使用礼貌用语,勤奋学习,能吃苦耐劳,保持谦虚谨慎,勤劳俭朴,孝敬父母,严于律己,遵守公德。养成良好的日常行为规范,是对自己的一种负责任的态度。播种一种行为,收获一种习惯;播种一种习惯,收获一种性格;播种一种性格,收获一种命运。”从而,我们可以知道:行为变成了习惯,习惯养成了性格,性格决定了命运。我们不能依靠别人,养成好的习惯的秘决在于自我克制。如果你学会了驾驭自己,那么你就有了一位最好的老师。
尊重老师同样也是我们学生必须做到的行为,古人曰:“一日为师,终身为父。”可见教师在人们心中的地位。作为学生应从心里敬重老师,尊重老师的人格。还要尊重教师的劳动。要虚心接受老师批评,不可当场顶撞老师。教师的辛勤劳动体现在教学上,学生虚心学习,认真听好老师的每堂课,取得良好的学习成绩,这是对老师最大的尊重。9月10日是我国的教师节,老师给了我们理想的阳光和智慧的阳光,老师引导我们走上洒满阳光的人生之路。各位老师,请接受我们诚挚的祝福吧,教师节快乐!同学们,我们要时刻注意自己的言行,配合教师的工作,关心老师的生活,以一颗赤诚的心去理解老师,把老师作为我们最敬重的人。我想,如果每一位同学都能够加入到自律者这个行列中来,时时刻刻注意自己的行为规范,把自己培养成一个遵纪守法、热爱科学、热爱祖国、热爱人民、诚实守信、有责任心的好学生,就会发现身边的事物、环境都会有很大的不同。我认为,养成良好的日常行为规范是走向成功的基石!
篇17:美丽乡村演讲稿
全文共 1140 字
+ 加入清单尊敬的各位领导、各位评委老师,大家上午好,我叫XXX,是来自XXX的一名普通职工。今天我演讲的题目是《风光景色一千里,梦绕江南云水乡》。
我是一个北方人,在我千里之外的家乡,有着与江南完全不同的景象。那里松劲山高、石多水少、阡陌连天、植被枯黄,少了许多江南水村山郭的诗情画意。虽然我是一个北方人,但我对杏花春雨江南,一直都有着一种难以割舍的情怀,渴望能够在诗画般的江南去实现自己的梦想。
三年前,正是怀着这样的梦想,我来到了XX,来到了XX。当我踏上这片以八宝之地著称的沃土后,我迷惑了,这难道就是我在梦里追寻了千百度的江南吗?
那时的这里没有小桥流水,有的是污水残桥;没有古朴的民居,有的是杂乱的农舍;没有石板街、一人巷,有的是纷扰的街市、泥泞的村道;当我穿梭于村落街市之间时,假劣产品不绝于市。还有很多农户因为打不开销路,守着当地的优良土特产一筹莫展。这样的景象怎能是令人魂牵梦萦的江南?一年一个样,三年大变样,特别是在县乡两级政府强力实施美好乡村建设以来,这里的环境变美了、村庄变靓了、人的精气神变爽了。
你看现在的XX村,连排成片的蔬菜大棚,白色的薄膜在阳光下耀眼,里面碧油油的蔬菜茁壮成长,丰富着XX市民的菜篮子,也鼓起了XX村民的钱袋子;
你看那XX村,整齐划一的乡村别墅,粉刷一新的房屋、干净整洁的街道让人难以相信这是在农村,齐整的绿化、统一的排水,早已和城市接轨,昔日的残墙破屋已然旧貌换新颜;你看那XX街道,曾经污水横流、垃圾遍地的“龙须沟”,如今已变成了休闲小广场,草皮铺起来了,绿树种上去了,体育健身器材也安装起来了,笑容洋溢在每个农民的脸上;你再看那XXX,明塘碧波荡,粉墙黛瓦重,家家户户的“文化墙”上既有人文历史介绍、水乡风景画,也有诗词书法、名言警句。还有那一湾荷塘,硕大的荷叶亭亭玉立,水乡的景色令人沉醉。真真是莲香生藕鱼虾肥,更见古桥犹存啊。
我们XX部门也在积极为美好乡村做贡献,深入田间地头,走遍街道村乡,开展食品监管,净化农村市场,让不合格商品无处身藏。倡导“一村一品”,打造“一所多标”,通过开展商标工作来兴业富民。XX的烧饼、XX村的禽蛋、XX的鱼鳖、XX的萝卜这些享誉一方的土特产,纷纷申请了注册商标,有的还申报了市知名商标、省著名商标。土特产打上了注册商标,就像插上了翅膀,一下子就飞出了XX,飞出了XX。仓廪实而知礼节,衣食足而知荣辱。随着居住环境的改善,生活水平的提高,一些陋习也在悄然改变。家庭之中子孝妻贤,邻里之间和睦相处,道德楷模层出不穷,“XX好人”纷纷涌现,文明礼让蔚然成风,美好乡村人人共建!
村村优美、家家富裕、处处和谐、人人幸福,可正是生态宜居村庄美、兴业富民生活美、文明和谐乡风美的美好乡村,这正是令人魂牵梦绕的江南云水乡!
篇18:科技创新演讲
全文共 884 字
+ 加入清单老师、同学们,早上好:
2008年11月29日,在福州科技馆,我参加了第24届福州市青少年科技创新大赛,我以环境科学组第一名的成绩,夺得了此次大赛的一等奖。在此,我特别感谢我的指导老师——吴瑞平老师和薛莲老师,她们在这次创新大赛中给了我悉心的指导。我还要感谢其他老师和同学,没有他们的支持,我也无法取得成功。
下面,我简要介绍一下参加此次创新大赛的过程与感想。
我是班级的宣传干部,班级的黑板报总是由我来出。每当我用粉笔写完黑板报后,总感觉接触粉笔的手很干燥,如果不及时的清洗,过不了多久手就会脱皮,难受极了!为什么会有这样的感觉呢?经过查询,我了解到,人的手接触粉笔后,皮肤粘膜会受到刺激,使皮肤变得干燥、粗糙,并伴有搔痒感觉,甚至脱皮。我对粉笔产生了巨大的兴趣。观察粉笔成了我每天的必修课:我发现教室粉笔槽中常有大量废弃的粉笔头;我发现老师的身上、头发上沾满白色的粉笔末;我发现上课时粉笔末在空气中飞扬……原来废弃的粉笔头每年要浪费数以亿计的原材料;原来粉笔末对健康和环境的危害无法估计;原来我亲爱的老师每天都被粉笔末包围!于是,我下决心改造粉笔!
我把这个想法跟指导老师做了交流,她们对此也非常感兴趣,于是我们开始了各种各样的尝试:戴手套上课?不行,不方便、不灵活;在粉笔后加一个塑料套来书写?不行,还是会浪费;把粉笔和黑板换成白板?不行,现实条件不允许。我们陷入了困境,但是大脑从来没有停止过对改造粉笔的思考。在一次剪贴报制作中,我突然发现固体胶的胶体能随着外壳装置的转动而内外伸缩,人的手不用接触胶体,只要抓住外壳就能完成粘贴的工作。把胶体换成粉笔!我激动得大叫出来。于是,我把整个固体胶来了一个大解剖——全部拆开,经过细致的观察,我发现只要找到与粉笔规格大小相匹配的固体胶外壳装置,就可以将粉笔像固体胶的胶体那样固定住。这样一来我就改造出了旋转式的环保粉笔,彻底解决了曾经困扰我的各种问题。
这次旋转式环保粉笔的创造,使我懂得了科学创意来源于生活,只有通过多观察、多动脑、勤动手,才会有所创新。同学们,事事留心皆学问!只要你做一个有心人,你就可以取得成功!
谢谢大家!
篇19:演讲稿作文:把信心留给自己_900字
全文共 899 字
+ 加入清单尊敬的各位老师,亲爱的同学大家下午好!今天我演讲的题目是:把信心留给自己。
信心是什么呢?信心就是一种力量,是对学习与生活充满乐观与进取的信念,是克服学习上,生活上遇到的困难的决心与勇气,是任何情况下都不动摇,并努力为之奋斗的动力源泉,是一种永不服输的精神。在人生路途中,信心尤为重要,信心是成功的保证,有了自信,事情便成功了一大半。
信心是火,信心是灯,信心是路。记得在一次语文考试中,我只考了68分!拿到卷子的那一刹那,我傻了,我的心也碎了!我不知如何开口与爸爸妈妈说出这个成绩?我更不敢想像他们看到这张卷子时,会有什么样的反应?但我知道,他们一定会伤心、失望、唠叨、恨我不争气的种种表情油然而生……这个可恶的68分,会让我时常洋溢欢乐的空气顿时凝固,想到这些,我的心情越来越沉,步子也变得越来越重,刚到家,爸爸好像就看出了我的心事,抢先一句就问:印印今天有什么不开心的事儿吗?爸……我错了,才考了68分。眼泪像断了线的珠子似的……这时父亲语重心长地对我说,失败是成功之母,下次重新来过,相信你一定能行!宽容与激励尤如一股暖流充溢在我全身,我对自己说:“振作起来吧!在学习之路上,失败并不可怕,可怕的是失去信心。加油,把这68分抛弃,让它成为我前进的动力。”
一个人,要想成为一个成功者,那么他首先要具备的是信心,如果没有信心,那他就不会成功。同学,也许你现在的成绩不好,不过,别怕!只要你还有一份自信;也许你现在正面临着一些困难,不要退缩,相信吧!你总会挺过去的。只要我们鼓起勇气去面对,就算我们失败了,我努力过!我无怨无悔!
我们是21世纪的主人,要着眼身边,立足校园,为把我县的南大门——平定营镇,建设成为文明生态区,把我校建设成为更加美丽,更加清洁的校园,我们都是环保卫士,要多弯弯腰捡捡果皮纸屑,不要随地乱扔乱丢,不要随便攀折花草树木。让我们共同满怀信心地投入到文明行动中去,相信明天我们的校园一定会变得更加灿烂迷人!
信心,如此平凡的字眼,但它却鼓舞着一个又一个的人为之拼搏、奋斗。把信心留给自己,就是把明天留给自己,把幸福留给自己,把成功留给自己!
同学们!让信心伴随着我们一起成长吧!
谢谢!

+ 加入清单Genghis Khan, "Khan of Khans", was the great leader of Mongolians. At the end of 12th century, he united Mongolian tribes and challenged other powers to expand his huge Mongolian empire, which extended from South China to the Caspian Sea.
In 1277, Khan attacked the West Xia Kingdom (presently Ningxia) and encountered strong resistance. He died of disease and age. The great emperor was later buried secretly according to Mongolian custom. It says that after the burial 2,000 men were slaughtered by some 800 soldiers who were in turn executed so that the location of the real tomb remains a secret.
There are four sacrifice ceremonies held annually to commemorate the great hero and leader of the Mongolian people. The ceremony, held on March 21st on lunar calendar, is the grandest. After the ceremony, horse racing, archery and wrestling are held as entertainment.
