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.
三分鐘優秀演講稿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(多媒體)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 (動畫) , 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.
三分鐘優秀演講稿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.
tobacco contributes to the hardening of the arteries, which can then become blocked and starve the heart of bloodflow, causing the attack.

us studies have shown that men who smoke increase their chances of dying from the disease by more than 22 times.
women who smoke increase this risk by nearly 12 times.
lung cancer is a difficult cancer to treat - long term survival rates are poor.
smoking also increases the risk of oral, uterine, liver, kidney, bladder, stomach, and cervical cancers, and leukaemia.
another health problem associated with tobacco is emphysema, which, when combined with chronic bronchitis, produces chronic obstructive pulmonary disease.

三分鐘優秀演講稿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!
三分鐘優秀演講稿7同學們，大家好。 今天十分榮幸可以由我來為大家進行課前三分鐘的演講。
首先，我要給大家分享一句話。“我寧願選擇驕傲也不選擇自卑。因為驕傲需要資本，資本需要積累，積累需要汗水，而自卑卻什麼也不需要。”這句話是我在看喬松樓將軍在復旦大學演講視訊時偶然間聽到的。
是的，今天我演講的主題就是自信。
每個人的人生都並非一帆風順，並非永無波浪的湖面。而是一場充滿艱辛，坎坷，曲折，充滿挑戰與挫折的旅途。屬於我們的每一個新的一天都是一次挑戰。在迎接每日的朝陽時，我們需要足夠的自信來克服遇到的困難。
愛因斯坦的“相對論”發表之後，有人曾炮製了一本《百人駁相對論》，網羅了一批所謂名流對這一理論進行聲勢浩大的撻伐。可是，愛因斯坦自信自己的理論必然勝利，對噠伐不屑一顧。他說：“假如我的理論是錯的，一個人反駁就夠了，一百個零加起來還是零。”他堅定了必勝的信念，堅持研究，終於使“相對論”成為20世紀的偉大理論，為世人所矚目。
同學們，或許我們無法成為像愛因斯坦一樣成為為社會做出極大貢獻的人。但我們依舊應該向他一樣自信的面對一切，面對困難，面對挫折。
居里夫人說過：“我們應該有恆心，尤其要有自信心!我們必須相信，我們的天賦是要用來做某種事情的，無論發生什麼事情，活著的人總要照常工作。”正是自信，支援她在經受了失戀、喪夫、社會上的流言蜚語等打擊之後，兩次榮獲了諾貝爾獎，為人類的科學事業做出了巨大的貢獻。
我堅信，自信是一種力量，一種引領我們堅持的力量。無論身處順境，還是逆境，都應該微笑地，平靜地面對人生，有了自信，生活便有了希望。“天生我材必有用”，哪怕命運之神一次次把我們捉弄，只要擁有自信，擁有一顆自強不息、積極向上的心，成功遲早會屬於你的。
同學們，高中三年必定是一段崢嶸歲月。希望從今天開始，從現在開始，我們都可以把汗水的積累轉化為驕傲，自信的資本。以捨我其誰也的雄心壯志面對我們應該面對的每一次考驗。 讓我們的高中生活成為人生光彩絢麗的回憶。
三分鐘優秀演講稿8親愛的教師們同學們，大家早上好，今日我國旗下講話的題目是：珍惜時間東晉詩人陶淵明曾有過這樣的感嘆："盛年不重來，一日難再晨，及時當勉勵，歲月不待人。"新的一天又開始了，有同學迎著晨光，伴著朝陽，大聲背誦、朗讀;有同學卻顯得無所事事;有同學在課堂上專心致志，心無旁騖;有同學卻忙於聊天，擺弄桌底的玩物;有同學在作業，複習中，書寫自我的刻苦;有同學卻身在教室、心在其它地方玩耍。
偉大的文學家高爾基說過：“青春是有限的，可是智慧是無窮的;要珍惜短暫的青春，去創造無窮的智慧。”同學們，時間老人是公平，慷慨的，每人每一天都24小時。可時間老人卻又是不公和吝嗇的：朗朗書聲的晨讀課，時間老人會無意停下腳步，與你一齊合奏美妙的交響曲;聚精會神的課堂，時間老人會作暫時逗留，和你共享知識的芳香;全身心投入的晚自修，時間老人會放慢步伐和你一齊品味學習的樂趣懶惰、散漫者只能被時間毫不留情地留下刺眼的分數，留一頭白髮，兩手空空，留下遺憾，悔恨和痛苦同學們，“勤奮生智慧，勤奮造天才”，知識的海洋是廣闊無垠的，學習是一種艱苦的勞動，不下苦功是學不好的。一個真正渴望得到知識的人必須珍惜時間，勤奮努力，練就堅持不懈的頑強毅力，向愚笨索取智慧，向平庸奪得天才。
歷史上流傳著很多古人苦學的故事，如鑿壁借光、懸樑刺股等等。被人們譽為“書聖”的王羲之，幾十年如一日，刻苦練筆，從不間斷，竟然將紹興蘭亭旁的一池清水變成“墨池”。宋朝詩人陸游一生酷愛讀書，在他房中，櫃裡裝書，桌上堆書，床上鋪書，他睡覺枕的還是書。世界著名科學家牛頓，很少在晚上二三點鐘以前睡過覺，為完成實驗，常常徹夜不眠。那種苦學精神是很可貴的。
人的一生僅有三天：昨日，今日和明天。昨日已留給記憶，明天將交給夢想，你所能把握的，就僅有今日!讓我們好好珍惜今日這完美時光吧!“莫等閒，白了少年頭，空悲切”。當熟悉的鈴聲又在耳畔響起、琅琅讀書聲又響遍菁菁學校的時候，同學們，珍惜時間，辛勤的耕耘吧!努力學習必須會給你帶來成功!預祝同學們在期末考試取得優異成績!
多謝大家我的演講完畢!
三分鐘優秀演講稿9尊敬的領導老師、親愛的同學們：
你們好!
踏著九月的金色陽光，你們完成了國小五年的學習生活，從今天開始你們就是一名國中生了，同為xx學校的一名學生，我們倍感自豪。今天，我有幸代表所有學生在這發言，心裡無比激動，首先向你們表示衷心的祝賀，和誠摯的歡迎。
我們的校園壯麗整潔，這裡有最好的領導，有學識淵博.認真負責的老師，有精神飽滿，好學上進，求實創新的學生。能融入到這樣的學習環境中，是我們每一個學生的幸運。這裡，綠色的校園是那麼的吸引人，五彩繽紛的花壇，綠草如茵的操場，似乎都在向我們招手。在明亮的教室中，與可親的同學一起學習，知識的大門向我們敞開。
我們進了最好的中學，就應該做最好的中學生。如何做最好的中學呢?我想，應該做到以下幾點;
一、認真學習《中學聲日常行為規範》，嚴格執行規範，用規範來指導自己的言行。
二、 樹立遠大理想，正確的人生觀，自覺抵制不良思想的侵襲，不接觸不健康.低階趣味的東西，學做品德高尚的人。
三、 明確學習目的，端正學習態度，認真學好各科文化，在班內形成“比學趕幫超”的氛圍。
四、 尊敬師長，團結同學。對學習有困難的同學大家要伸出援助之手，多指導，多關心，以達到共同提高的目的。
五、 要自強自立，作為中學生我們不能象國小生那樣，事事要父母操心，我們應當自己來管好自己的生活、學習。
六、 要多讀書，讀好書，寬闊自己的知識面，去欣賞優秀的書籍，在書海中遨遊。
同學們，“寶劍鋒從磨礪出，梅花香自苦寒來。”我們只有付出了，才會有收穫。相信在學校領導的關心下，在老師的辛勤培育下，經過我們不懈的努力，三年後，我們一定會成長為有理想，有道德，有文化，守紀律的合格中學生，給社會，給學校，給家庭一份合格的答卷。
三分鐘優秀演講稿10你看校園裡：操場上乾乾淨淨無紙屑，四周圍綠樹草皮話爛漫，樓房整齊一排排，同學們穿紅著綠好漂亮，外面還有綠水青山來擁抱，誰敢說我們的校園不美嗎啊？可是今天，老師要實話實說：我們的校園裡還有美中的`不足，還存在著"醜"的東西。
那麼這個"醜"到底藏在哪裡呢？
我說這個"醜"就藏在一些同學的嘴巴里。前些天，我路過教室門口，竟聽到有同學在相互傳唱這樣的一首打油詩：（什麼）讀書苦啊，讀書累，讀書還要繳學費，不如參加混混組織，有吃有喝有地位。
下面還有更難聽的，我也不好意思給大家再背下去了。當時，我心情沉重地回到了辦公室，跟老師聊起這樣的事情。老師們在生氣之餘告訴我，前些時候還流傳過這樣一個順口溜：（什麼）一年級是小偷二年級是賊，三年級的美女沒人追，四年級的帥哥排成對，五年級的情書滿天飛，六年級的鴛鴦成雙對。
這是什麼話？是怎樣的人編造的？其編造的目的又在哪裡呢？同學們對這樣的一些問題思考過嗎？昨天，老師對這些問題，思考了一個晚上，現在我的回答是很肯定的，對於第一個問題--這是些什麼話？我說是瞎話瞎講，以為根本沒有這個事實，純屬胡編亂造。第二個問題--是些怎樣的人胡編亂造的？我的回答是：是一些胸無大志，不願學習，只貪圖眼前舒服與享受的，又別有用心的人編造的。他們的別有用心又再哪裡呢？--他們學壞了，還想讓更多的人也跟著學壞。打個比方，他們已經落水了，快要淹死了，還想多找幾個人下水陪他們一起淹死，這就是他們的目的。所以，同學們一定要小心啊!
古人說："言為心聲"，就是說，一個人的語言直接反映了他的思想。有人說，眼睛是心靈的窗戶，我說，語言是心靈的一面鏡子，什麼樣的語言就是一個什麼樣的人，如果想做一個文明的學生，首先應該從學會說文明的語言開始。
校園是教育人，培養人，塑造人的地方，校園應該是一個美麗而純潔的地方，所以我們絕不允許此類不文明語言來玷汙我們美麗純潔的校園，毒害小朋友們純潔美麗的心靈，大家說，對嗎？
讓我們行動起來，自覺地抵制這些不文明語言的傳播。 讓我們行動起來，人人都來自覺地使用文明禮貌語言。
讓我們人人都來用美麗的語言，給我們的校園再添一份美吧
