The power of self-confidence is not to be underestimated, however, confidence is not everyone have, people with low self-esteem will not have it, if we are confident, that is not confident, but arrogance. So, confidence also wants moderate, should not be too.
People with low self-esteem is not successful, because they are afraid of difficulties, fear of the unknown dangers, think you what all can't, no, in fact they are wrong, this is the result of their lack of confidence, things did not difficult, as they think they are not as useless as they want. As long as they look ahead, give yourself a little more encouragement, and say to myself: I can do it! Don't be afraid in front of the unknown is difficult, only go forward, never fear, self-confidence will come to your side.
At any time, all want to learn self-confidence, frankly, smile in the face of all, doing everything to an unyielding, don't give up easily, say to yourself: I can do it! Self-confidence, power is endless, let us smile confidently towards our own success.
三分钟优秀演讲稿2ladies and gentlemen,
i have had a lot of teachers in my school who have given me much help in my study. for their help i will never forget them. but today i am going to talk about a special teacher of mine. this teacher is not a human being and its name is“computer”. it has been teaching me a lot of knowledge and i appreciate it very much.
with the development of modern science and technology, computers are widely used in every teritories (1) including education. how can a computer be my teacher? how does a computer teach me? multimedia(多媒体)helps a lot in this aspect in recent years, and computer-based training (cbt) has become a popular educational medium (手段). even before the multimedia come (2) up, many different learning systems appeared, using the components and techniques we now associate with the term “multimedia”. multimedia components, such as graphics (动画) , animations , sound and video, make the learning process easier through visualization. animations can present many complex subjects dynamically, but human teachers can not do this on blackboards.
multimedia makes our study more lively and interesting. for example, a cd-rom disk named “encarta encyclopedia” contains 650 mb
information including images, graphics, music clips, video clips,
animations , texts, hotwords, and database search functions. fields involved includes physical sciences, performance arts, social
sciences, politics, military, education and so on. when pressing a button, i can hear american president clinton's speech clip. i may enjoy playing all kinds of musical instruments in the world. i can also see the animation of many physical phenomena. this makes
physical concept to be understood deeply (3). the audio features of multimedia can greatly help me learning (4) foreign languages. with its speech output capabilities, i'm no longer dependent on an instructor for proper pronunciation.
how can i interact with a computer? there are many ways,
including keyboard, mouse pointer, and touch screen. i often use a
keyboard. when i press right keys, i can see and hear whatever i want. information world is at my fingertip. i wish that true speech input-output system would be invented one day.
as teachers, computers have a lot of virtues： they are positive, they have good memories and never lose any information stored in them. they have much knowledge in every field. they can let out all kinds of sounds, and can also improve the efficiency of our study. for example, if i want to, i can skip some chapters so that i can study at my own pace.
三分钟优秀演讲稿3Confidence, in a broad sense, comprises self-trust,self-esteem, courage and indomitability.
This definition,though somewhat vague and unsubstantial, can be appreciated through experience because iff our lifetime, we are always seeking to achieve something successful and are always longing.
To attain a glorious goal, which can only be reached with the spirit of self confidence.
As is known, self-confidence is accompanied by will, and that as a twin, offers hope.
Those who do not have a strong will often think themselves unable to carry out any thorny tasks, while those who have do not find the tasks unsurmountably difficult.
In fact, when our heart is void of selfconfidence, every hope is gone, every thing on which we put our hands seems to be veiled in dark.
For instance, according to experts, every year in the entrance examinations of all kinds, fully-prepared candidates lose nearly 5% to 10% of the full scores, and consequently meet their Waterloo simply because they underestimate their own abilities, on the one hand,and overestimate possible difficulties on the other.
As a result, their fear to meet new challenge leads to helplessness in the examination.
Self-confidence can be regained (if you have ever lost it) by building faith in ,whatever you do, you will encounter hardships.
Put success Will come to you if you are courageous enough to strive for it. If you are not, failure might be your life-companion.

tobacco smoking is a known or probable cause of approximately 25 diseases, and even the who says that its impact on world health is not fully assessed.
heart attack and stroke
uk studies show that smokers in their 30s and 40s are five times more likely to have a heart attack than non-smokers.

三分钟优秀演讲稿6Good afternoon ，ladies and gentlemen!
I’m very honored to stand here and give you a short speech! To begin with ,I want to ask a question everybody dream a good dream last night? Actually ,today I want to talk about dream with you. Of course, What I want to talk is not a dream you have last night,but a dream—— about life.
Everyone has dreams about life, different dreams at different life stage,and we need dreams to support us. Dreams are like the stars we never reach in the sky,but like most mariners(水手),we can chart our course by them. With the dream,we have a direction,with a direction, we were no longer the dream, there is hope,With hope, we have the strength to fight.
I have a dream: To be a doctor.，because doctor may relieve the pain of patients. May let the human change the health. At the same time, I believed that, those who help others may be able to obtain joyfully. Therefore, I hoped in the near future ,I might be a doctor.
But I know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead .
Young!Fortunately, I am young now. Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way. If I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses. If no people believe you, you can make it to prove that you are right. If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.
"My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains." At some time in the past I also had am bitious words and I had some achievements. Each achievement results from my hard work. I always believe that "If you want to have more achievements than others, you must work harder." In some extent, the dream is the hope. If you can insist on doing something, the victory will come.
Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today. Let's--- move ----out!
Thank you for your listening!
三分钟优秀演讲稿7同学们，大家好。 今天十分荣幸可以由我来为大家进行课前三分钟的演讲。
首先，我要给大家分享一句话。“我宁愿选择骄傲也不选择自卑。因为骄傲需要资本，资本需要积累，积累需要汗水，而自卑却什么也不需要。”这句话是我在看乔松楼将军在复旦大学演讲视频时偶然间听到的。
是的，今天我演讲的主题就是自信。
每个人的人生都并非一帆风顺，并非永无波浪的湖面。而是一场充满艰辛，坎坷，曲折，充满挑战与挫折的旅途。属于我们的每一个新的一天都是一次挑战。在迎接每日的朝阳时，我们需要足够的自信来克服遇到的困难。
爱因斯坦的“相对论”发表之后，有人曾炮制了一本《百人驳相对论》，网罗了一批所谓名流对这一理论进行声势浩大的挞伐。可是，爱因斯坦自信自己的理论必然胜利，对哒伐不屑一顾。他说：“假如我的理论是错的，一个人反驳就够了，一百个零加起来还是零。”他坚定了必胜的信念，坚持研究，终于使“相对论”成为20世纪的伟大理论，为世人所瞩目。
同学们，或许我们无法成为像爱因斯坦一样成为为社会做出极大贡献的人。但我们依旧应该向他一样自信的面对一切，面对困难，面对挫折。
居里夫人说过：“我们应该有恒心，尤其要有自信心!我们必须相信，我们的天赋是要用来做某种事情的，无论发生什么事情，活着的人总要照常工作。”正是自信，支持她在经受了失恋、丧夫、社会上的流言蜚语等打击之后，两次荣获了诺贝尔奖，为人类的科学事业做出了巨大的贡献。
我坚信，自信是一种力量，一种引领我们坚持的力量。无论身处顺境，还是逆境，都应该微笑地，平静地面对人生，有了自信，生活便有了希望。“天生我材必有用”，哪怕命运之神一次次把我们捉弄，只要拥有自信，拥有一颗自强不息、积极向上的心，成功迟早会属于你的。
同学们，高中三年必定是一段峥嵘岁月。希望从今天开始，从现在开始，我们都可以把汗水的积累转化为骄傲，自信的资本。以舍我其谁也的雄心壮志面对我们应该面对的每一次考验。 让我们的高中生活成为人生光彩绚丽的回忆。
三分钟优秀演讲稿8亲爱的教师们同学们，大家早上好，今日我国旗下讲话的题目是：珍惜时间东晋诗人陶渊明曾有过这样的感叹："盛年不重来，一日难再晨，及时当勉励，岁月不待人。"新的一天又开始了，有同学迎着晨光，伴着朝阳，大声背诵、朗读;有同学却显得无所事事;有同学在课堂上专心致志，心无旁骛;有同学却忙于聊天，摆弄桌底的玩物;有同学在作业，复习中，书写自我的刻苦;有同学却身在教室、心在其它地方玩耍。
伟大的文学家高尔基说过：“青春是有限的，可是智慧是无穷的;要珍惜短暂的青春，去创造无穷的智慧。”同学们，时间老人是公平，慷慨的，每人每一天都24小时。可时间老人却又是不公和吝啬的：朗朗书声的晨读课，时间老人会无意停下脚步，与你一齐合奏美妙的交响曲;聚精会神的课堂，时间老人会作暂时逗留，和你共享知识的芳香;全身心投入的晚自修，时间老人会放慢步伐和你一齐品味学习的乐趣懒惰、散漫者只能被时间毫不留情地留下刺眼的分数，留一头白发，两手空空，留下遗憾，悔恨和痛苦同学们，“勤奋生智慧，勤奋造天才”，知识的海洋是广阔无垠的，学习是一种艰苦的劳动，不下苦功是学不好的。一个真正渴望得到知识的人必须珍惜时间，勤奋努力，练就坚持不懈的顽强毅力，向愚笨索取智慧，向平庸夺得天才。
历史上流传着很多古人苦学的故事，如凿壁借光、悬梁刺股等等。被人们誉为“书圣”的王羲之，几十年如一日，刻苦练笔，从不间断，竟然将绍兴兰亭旁的一池清水变成“墨池”。宋朝诗人陆游一生酷爱读书，在他房中，柜里装书，桌上堆书，床上铺书，他睡觉枕的还是书。世界著名科学家牛顿，很少在晚上二三点钟以前睡过觉，为完成实验，常常彻夜不眠。那种苦学精神是很可贵的。
人的一生仅有三天：昨日，今日和明天。昨日已留给记忆，明天将交给梦想，你所能把握的，就仅有今日!让我们好好珍惜今日这完美时光吧!“莫等闲，白了少年头，空悲切”。当熟悉的铃声又在耳畔响起、琅琅读书声又响遍菁菁学校的时候，同学们，珍惜时间，辛勤的耕耘吧!努力学习必须会给你带来成功!预祝同学们在期末考试取得优异成绩!
多谢大家我的演讲完毕!
三分钟优秀演讲稿9尊敬的领导老师、亲爱的同学们：
你们好!
踏着九月的金色阳光，你们完成了小学五年的学习生活，从今天开始你们就是一名初中生了，同为xx学校的一名学生，我们倍感自豪。今天，我有幸代表所有学生在这发言，心里无比激动，首先向你们表示衷心的祝贺，和诚挚的欢迎。
我们的校园壮丽整洁，这里有最好的领导，有学识渊博.认真负责的老师，有精神饱满，好学上进，求实创新的学生。能融入到这样的学习环境中，是我们每一个学生的幸运。这里，绿色的校园是那么的吸引人，五彩缤纷的花坛，绿草如茵的操场，似乎都在向我们招手。在明亮的教室中，与可亲的同学一起学习，知识的大门向我们敞开。
我们进了最好的中学，就应该做最好的中学生。如何做最好的中学呢?我想，应该做到以下几点;
一、认真学习《中学声日常行为规范》，严格执行规范，用规范来指导自己的言行。
二、 树立远大理想，正确的人生观，自觉抵制不良思想的侵袭，不接触不健康.低级趣味的东西，学做品德高尚的人。
三、 明确学习目的，端正学习态度，认真学好各科文化，在班内形成“比学赶帮超”的氛围。
四、 尊敬师长，团结同学。对学习有困难的同学大家要伸出援助之手，多指导，多关心，以达到共同提高的目的。
五、 要自强自立，作为中学生我们不能象小学生那样，事事要父母操心，我们应当自己来管好自己的生活、学习。
六、 要多读书，读好书，宽阔自己的知识面，去欣赏优秀的书籍，在书海中遨游。
同学们，“宝剑锋从磨砺出，梅花香自苦寒来。”我们只有付出了，才会有收获。相信在学校领导的关心下，在老师的辛勤培育下，经过我们不懈的努力，三年后，我们一定会成长为有理想，有道德，有文化，守纪律的合格中学生，给社会，给学校，给家庭一份合格的答卷。
三分钟优秀演讲稿10你看校园里：操场上干干净净无纸屑，四周围绿树草皮话烂漫，楼房整齐一排排，同学们穿红着绿好漂亮，外面还有绿水青山来拥抱，谁敢说我们的校园不美吗啊？可是今天，老师要实话实说：我们的校园里还有美中的`不足，还存在着"丑"的东西。
那么这个"丑"到底藏在哪里呢？
我说这个"丑"就藏在一些同学的嘴巴里。前些天，我路过教室门口，竟听到有同学在相互传唱这样的一首打油诗：（什么）读书苦啊，读书累，读书还要缴学费，不如参加混混组织，有吃有喝有地位。
下面还有更难听的，我也不好意思给大家再背下去了。当时，我心情沉重地回到了办公室，跟老师聊起这样的事情。老师们在生气之余告诉我，前些时候还流传过这样一个顺口溜：（什么）一年级是小偷二年级是贼，三年级的美女没人追，四年级的帅哥排成对，五年级的情书满天飞，六年级的鸳鸯成双对。
这是什么话？是怎样的人编造的？其编造的目的又在哪里呢？同学们对这样的一些问题思考过吗？昨天，老师对这些问题，思考了一个晚上，现在我的回答是很肯定的，对于第一个问题--这是些什么话？我说是瞎话瞎讲，以为根本没有这个事实，纯属胡编乱造。第二个问题--是些怎样的人胡编乱造的？我的回答是：是一些胸无大志，不愿学习，只贪图眼前舒服与享受的，又别有用心的人编造的。他们的别有用心又再哪里呢？--他们学坏了，还想让更多的人也跟着学坏。打个比方，他们已经落水了，快要淹死了，还想多找几个人下水陪他们一起淹死，这就是他们的目的。所以，同学们一定要小心啊!
古人说："言为心声"，就是说，一个人的语言直接反映了他的思想。有人说，眼睛是心灵的窗户，我说，语言是心灵的一面镜子，什么样的语言就是一个什么样的人，如果想做一个文明的学生，首先应该从学会说文明的语言开始。
校园是教育人，培养人，塑造人的地方，校园应该是一个美丽而纯洁的地方，所以我们绝不允许此类不文明语言来玷污我们美丽纯洁的校园，毒害小朋友们纯洁美丽的心灵，大家说，对吗？
让我们行动起来，自觉地抵制这些不文明语言的传播。 让我们行动起来，人人都来自觉地使用文明礼貌语言。
让我们人人都来用美丽的语言，给我们的校园再添一份美吧
