3分钟演讲稿 关于自信
记着采纳哦
谢谢
爱默生说过：自信是成功的第一秘诀。
自信，就是自己信得过自己，自己看自己。
它，不是孤芳自赏，也不是夜郎自大，更不是得意忘形，毫无根据的自以为是和盲目乐观：而是激励自己奋发进取的一种心里素质，是以高昂的斗志，充沛的干劲迎接生活挑战的一种乐观情绪，是战胜自己，告别自卑，摆脱烦恼的一种灵丹妙药。
在漫漫人生旅途中，我们笑过，哭过，我们成功过，失败过。
挫折，失败也许曾一点点的慢慢吞噬你的信心，使你胆怯。
但是，朋友们，失败，它并不可怕，可怕的是它带来了自卑。
在不知不觉中，它消磨软化我们的信念，钝化我们的锐气，使我们畏缩不前。
于是，我们开始怀疑自己，否定自己，最后自我消沉。
曾经，我多么想实现我心中的理想，但是我退却了。
因为失败，因为自卑。
我觉得自己是一只多么渺小的丑小鸭。
无论我怎样发奋努力，我永远不可能拥有变成白天鹅的那一天
就这样，自卑，它蒙蔽了我的双眼，我看不见前方的阳光大道。
直到有一天，我看到了爱因斯坦的传记。
这个科学巨人，小时候，他被老师们称为弱智。
但他的母亲却时时鼓励他，使他找回自信。
正是因为这自信，他成功了
他发表了《相对论》，他成为了科学巨人
今天，在我重新找回自信之后，我要向你们真诚的说声：朋友们，自信吧
没有自信，谁也不可能成功
朋友们，选择自信吧。
告别自卑的阴影，去创造自己辉煌的人生。
自信是成功的关键。
只有拥有自信，才能拥有自我：只有拥有自信，才能走向成功
自信，是成功的伴侣，是战胜困难的利剑。
只有它才能让我们达到理想的彼岸。
诗仙李白，他发出了“仰天大笑出门去，我辈岂是逢蒿人”的浩叹，他自信“天生我材必有用，千斤散尽还复来”：伟大主席，他写下“自信人生二百年，会当击水三千里”，他骄傲“数风流人物，还看今朝”。
他们都成功了，因为他们拥有了自信。
自信，是成功的关键。
有了自信，一对足便能穷尽大漠沙海，让脚下飘起丝绸之路：有了自信，一双手便能雕绘出莫高窟的金碧辉煌，托起“神州号”在宇宙中遨翔
自信，是成功的关键，我相信，有了自信，我们×班，从此刻起，都会让所有的人感到自豪，感到骄傲
自信，是走向成功的伴侣，是战胜困难的利剑，是达向理想彼岸的舟楫。
有了它，就迈出了成功的第一步；有了它，就走上了义无反顾的追求路。
曾几何时，刘邦、项羽目睹秦始皇浩浩荡荡的出游队伍、富丽华美的车帐、八面凛凛的威风，随生雄心万丈的自信：“大丈夫当如此也”，“彼可取而代也”。
于是，汉高祖立千秋帝王大业，楚霸王成万古悲壮英雄。
诗人李白自信，他发出了“天生我才必有用，千金散尽还复来”、“仰天大笑出门去，我辈岂是蓬蒿人”的浩叹，便有壮丽辉煌的诗章千古流传。
巴尔扎克自信，放弃家人为他选定的职业，毅然走上创作道路，终有惊天动地的《人间喜剧》彪炳千秋。
一代伟人更自信，他高唱“自信人生二百年，会当击水三千里”、“数风流人物，还看今朝”，万水千山，披荆斩棘，铸造了共和国的辉煌，带来了亿万人民的幸福…… 有了自信，中华民族便有了无数追求成功的动人的故事：“头悬梁，锥刺骨”、“凿壁偷光”、“囊萤映雪”……有了自信，一双脚便能穷尽大漠沙海，脚下就飘起“丝绸之路”，身后就有“丝路花雨”；有了自信，一双手便能雕绘出莫高窟的金碧辉煌，筑起葛洲坝“截断巫山云雨”，托起“神州号”飞船遨游神秘的天宇。
自信不是狂妄自大，也不是心血来潮，更不是“宁信度，勿自信也”形而上学的固执。
它是理想进取中折射出的生命的灵光，是孜孜追求路途中永恒的生命潮汐，是成功碑塔下第一块灵活辩证的基石。
字串3 自信吧，朋友
有了自信，才会拥有自我，才会拥有成功，才会拥有辉煌灿烂的人生

3分钟演讲稿,关于美国
美利坚合众国（英语：United States of America），简称美国，旧称花旗国，是由50个州和一个联邦地区组成的联邦立宪制共和国。
美国本土位于北美洲中部，东濒大西洋，西滨太平洋，北靠加拿大，南接墨西哥及墨西哥湾；首都华盛顿哥伦比亚特区与除夏威夷州和阿拉斯加州之外的48个州都位于美国本土。
阿拉斯加州位于北美大陆西北方，东接加拿大，西隔白令海峡与俄罗斯隔海相望。
夏威夷州则是太平洋中部的群岛。
此外，美国在加勒比海和太平洋还拥有多处领土和岛屿地区。
美国源自于1776年脱离英国统治的北美殖民地，13州的殖民地代表一同发表了《美国独立宣言》，在经历艰苦的独立战争后，于1783年与英国签订了《巴黎条约》，从此受到世界各国的承认。
经过两百多年的发展，美国国土不断拓展，37个州陆续加入联邦旗下。
目前有50个州，1个联邦直辖特区，以及若干境外领土。
国土面积超过962万平方公里，国土面积位居世界第三或第四名（领土排名争议参见地理一节）。
美国人口约3亿人，其数量为世界第三，民族多元，以白人为主，有大量移民人口。
美国国旗上的50颗白色星星代表50个州；每当有新州加入联邦时，美国国旗会在次年的独立日（7月4日）时增加一颗星。
[2]国旗上红色及白色横条各为7条及6条，总计13条，纪念最初独立的13个州。
[3]建国200多年以来，美国曾经历过南北战争（1861－1865年）和大萧条（1930年代）两次严酷考验，[4]仍坚守自由民主制政治制度，成为宪法民主和公民自由的代表性国家。
美国庞大的经济、文化、科技和军事影响力贯穿了整个20世纪。
在第一次世界大战和第二次世界大战中，美国和其他同盟国一同获得胜利，并经历数十年的冷战后，终于拖垮苏联，成为现今世界上唯一的超级大国[5]。
当今美国在全世界的经济发展、政治实力、科技创新、军事技术力量等众多领域的庞大影响力都是无他国能比拟的。
The United States of America (commonly referred to as the United States, the U.S., the USA, or America) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Caribbean and Pacific.At 3.79 million square miles (9.83 million km2) and with about 308 million people, the United States is the third or fourth largest country by total area, and the third largest both by land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries.[7] The U.S. economy is the largest national economy in the world, with an estimated 2008 gross domestic product (GDP) of US $14.4 trillion (a quarter of nominal global GDP and a fifth of global GDP at purchasing power parity).[4][8]Indigenous peoples, probably of Asian origin, have inhabited what is now the mainland United States for many thousands of years. This Native American population was greatly reduced by disease and warfare after European contact. The United States was founded by thirteen British colonies located along the Atlantic seaboard. On July 4, 1776, they issued the Declaration of Independence, which proclaimed their right to self-determination and their establishment of a cooperative union. The rebellious states defeated Great Britain in the American Revolutionary War, the first successful colonial war of independence.[9] The Philadelphia Convention adopted the current United States Constitution on September 17, 1787; its ratification the following year made the states part of a single republic with a strong central government. The Bill of Rights, comprising ten constitutional amendments guaranteeing many fundamental civil rights and freedoms, was ratified in 1791.In the 19th century, the United States acquired land from France, Spain, the United Kingdom, Mexico, and Russia, and annexed the Republic of Texas and the Republic of Hawaii. Disputes between the agrarian South and industrial North over states' rights and the expansion of the institution of slavery provoked the American Civil War of the 1860s. The North's victory prevented a permanent split of the country and led to the end of legal slavery in the United States. By the 1870s, the national economy was the world's largest.[10] The Spanish–American War and World War I confirmed the country's status as a military power. It emerged from World War II as the first country with nuclear weapons and a permanent member of the United Nations Security Council. The end of the Cold War and the dissolution of the Soviet Union left the United States as the sole superpower. The country accounts for two-fifths of global military spending and is a leading economic, political, and cultural force in the world.
急求my dream 演讲稿，3分钟左右。
谢了
这是以前帮小妹写的，不知你能用上不
请指正Ladies and gentlemen, Good morning! It’s my great honor to be here, and I’m very happy to see you all! Thank you for being here. What I'm going to talk about is Courage —— A Weapon To Defeat Death. Do you want to challenge yourself? Do you want to achieve unusual success? Do you want to win the respect and appreciation of others? Be brave! Be braver. Be even more braver. You can achieve all of these! It is well known that the only thing that strikes fear into anybody is death. But those who have enormous courage can confront it fearlessly. We still remember one word, S-A-R-S, SARS. It broke out in December last year in Guang Dong province and soon rampaged our whole country. Thinking back to the days when SARS was a raging epidemic, thousands of people were infected and hundreds of people died of it. People didn’t know where the deadly strange new disease came from and how to treat it. At that very moment, the medical staff, battling with that notorious invisible enemy, actually were frightened of becoming infected and possibly transmitting that disease to their loved ones. However, they were not scared to death. On the contrary, they kept on working all day and all night. The early recovery of the SARS patient was what they were all hoping for. What support them? It’s the bravery. It’s the courage. It’s the sworn oath of a health care worker: to do what they could do for the sick. The final smile on their faces was the symbol of victory over death. Here, I want to pay tribute to those medical staff who fought the battle against SARS, and to those who gave their endless warm-hearted encouragement and support. Finally, I'd like to summarize my point in one sentence —— where there is bravery, there is the hope! Thank you for listening. Thank you very much.
求300字演讲稿，要求时间3分钟左右，3个主题关于青春、、为自己喝彩、、珍惜自己，可以随便选一个主题
为自己喝彩人的一生，缺点数不胜数，而优点却屈指可数。
但“人无完人，金无足赤”。
我们总要为自己的某些优点而高兴，而喝彩
不是吗
所以，我为自己喝彩
就拿上次考试来说吧
一位同学找不到他的尺子了
急得犹如热锅上的蚂蚁。
他是在没法子了，所以转过身来，低声细语地说：“我可以用一下你的尺子吗
”我看着他那狼狈样儿，便爽快地借给了他。
他拿着尺子，如获至宝。
对我这般“仗义相救”连连道谢。
这时，我头顶仿佛飘着一朵幸福的云，啊
我好快乐
因为，我帮他“赢得”了那道题的分，为我们的平均分又增添了几道不起眼的光环
我为自己的乐于助人喝彩
我还爱唱歌
在家里，我唱网络流行曲，成为引领潮流的“时尚新人”
让爸爸妈妈的耳朵也年轻年轻。
在学校我唱《我爱上学》，让同学们更开心，更舒心。
每当我听到别人夸我的歌唱得好的时候，我心里甭提有多高兴了
这下，我又为自己的演唱成功而喝彩
…… 我为自己喝彩，为我所有的优点喝彩。
哪怕它们是多么的微不足道，我就是要为自己喝彩
你为自己喝彩过了吗
有关环保的英语演讲稿，3-5分钟左右
（1） With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life. My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends? 与我们的生活水平的提高,越来越多的人都买得起汽车的。
因此,道路往往没有堆满了汽车。
然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重。
所以现在我们提倡过低碳的生活。
我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境。
为什么不试试,我亲爱的朋友?（2） Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment. 现在，我们身边的汽车不断的多了起来，环境也越来越糟糕
以至于我们周围的空气有很多有害物质。
所以，我们要苏身边的小事做起。
比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。
有时间的话可以少用电梯，多爬楼梯。
我们不仅能锻炼身体,也能保护我们的环境。
（3）文章文体：议论文。
文章要点：1.保护环境的重要性；2.学生在家庭中节约能源的具体做法和感想；3.今后的打算。
文章框架：文章应该是三部分两段式。
第一段（包括要点前两部分）1.环保的重要性；2 接着是站在学生的角度谈谈家庭节约能源的具体方法，第二段写第三要点，即谈谈今后打算。
重要句型短语：It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste，I can learn more to develop new and clear energy, like the energy from the wind and solar 等。
参考例文： With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars. Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.（4）Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. (最近我们班开了个班会讨论什么是光荣和耻辱。
)It is really a pity to see all this in our school.(很遗憾在学校看到这些现象)Some students don’t respect their teachers or parents. (不尊敬老是和父母)Some don’t take their studies seriously and cheat in exams. (作业不认真，考试作弊)Some throw wastes everywhere and pollute the environment . (到处乱扔垃圾污染环境。
)It is honorable to obey the law and rules , care much about our class and study hard.(关心班级、努力学习、遵纪守法是光荣)It is shameful to break school rules, to be selfish or to make little effort to achieve success.(违反学校纪律、自私 骄傲是可耻的)We should respect others and think more of them than of ourselves.(我们应该尊敬别人经常关心别人)We should work hard and make much more progress to repay the society.(我们应该努力学习取得更大进步从而回报社会。
)We should try our best to keep the environment clean。
(我们应该想方设法保持干净的环境。
) （5） There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.保护环境目前环保还存在着许多问题。
最严重的问题就是空气、水和土壤的严重污染。
污染的空气对人类的健康十分有害。
污染的水引起疼病，造成死亡。
更有甚者，随着现代社会的迅速扩建，植被大大的减少。
为了保护环境，各国政府做了大量的工作。
采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。
因此，在当今的环保中政府起着最重要的作用。
我的看法是，为了保护环境，政府应当采取更具体的措施。
首先，应当通过教育的方法使人们充分謒到环境保护的重要性。
第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。
最后，要严惩那些故意破坏环境者。
使他们破坏环境就是毁灭人类自己。
Hello: everyone!Now I want to talk about a beatiful world! When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment. Taking care of our environment is very important.Where ever you live,you can do something around your neighbourhood. Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls? Have you ever cut down trees?If your answers are No,it means that you have already helped protect our environment. It is our duty to keep our envionment clean and tidy. You might ask yourself,Have I ever picked up some rubbish and thrown it into a box?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?If your answers areYes,it means that you have already done something useful to improve the environment.
