美国撕演讲稿

⑴ 谁有美国各大总统的经典演讲稿谢谢。

演讲者简介： 约翰·肯尼迪是一位战争英雄，普利策奖获得者，五十年代大部分时间里的参议员。1960年的月，年仅43岁的他成为美国历史选择产生的最年轻的总统。1963年11月22日他在德克萨斯州的达拉斯遇刺身亡，是美国历史上第四位死于暗杀者的子弹的总统。 Let the word go forth, from this time and place, to friend and foe alike, that the torch has been passed to a new generation of Americans, born in this century tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage and unwilling to witness, or permit, the slow undoing of those human rights to which this nation has always been committed, and to which. we are committed today at home and around the world. 此时，让这个声音从这里同时向我们的朋友和敌人传达：火炬现已传递到新一代美国人手中——他们生于本世纪，既经受过战火的锤炼，又经历过艰难严峻的和平岁月的考验。他们深为我们古老的遗产所自豪——决不愿目睹或听任诸项人权受到无形的侵蚀，这些权利不仅为这个国家始终信守不渝，亦是我们正在国内和世界上誓死捍卫的东西。 Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty. 让每一个国家都知道，无论它们对我们抱有善意还是恶意，我们都准备付出任何代价、承受任何重任、迎战任何艰险、支持任何朋友、反对任何敌人，以使自由得以维系和取得胜利。 To those new states whom we welcome to the ranks of the free, we pledge our words that one form of colonial control shall not have passed away merely to be replaced by a far more iron tyranny We sha1l not always expect to tind them supporting our view, but we shall always hope to find them strongly supporting their own freedom, and to remember that in the past, those who foolishly sought power by riding the back of the tiger ended up inside. 对那些我们欢迎其加入到自由行列中来的新国家，我们恪守我们的誓言：决不让一种更为残酷的暴政来取代一种消失的殖民统治。我们并不总是指望他们会支持我们的观点。但我们始终希望看到他们坚强地维护自己的自由--而且要记住，在历史上，凡愚蠢地狐假虎威者，终必葬身虎口。 To our sister republics south of our border, we offer a special pledge: to convert our good words into good deeds, in a new alliance for progress, to assist free men and free governments in casting off the chains of poverty. 对于我们的南部邻邦共和国，我们许以特殊的承诺：将我们的良言转为善行，在为了进步而结成的新盟邦里，帮助自由的人民和自由的政府摆脱贫困。 So let us begin anew -- remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. 因此让我们重新开始，双方都记住：礼让并不表示软弱，而诚意则永远需要验证。 Now the trumpet summons us again, not as a cal1 to bear arms, though arms we need, not as a call to battle, though in battle we are, but a call to bear the burden of a long, twilight struggle, year in and year out, rejoicing in hope, patient in tribulation, a struggle against the common enemies of man: tyranny poverty disease, and war itself. 现在，号角已再次吹响---不是召唤我们拿起武器，虽然我们需要武器；不是召唤我们去作战，虽然我们严阵以待。它召唤我们为迎接黎明而肩负起漫长斗争的重任，年复一年，从希望中得到欢乐，在磨难中保持耐性，对付人类共同的敌人---专制、社团、疾病和战争本身。 就贴这么多吧，此篇演讲可谓是一篇经典之作，之后几位总统就职演讲中曾屡次引用过，比如其中的"And so my fellow Americans, ask not what your country can do for you, ask what you can do for your country."

⑶ 谁有简介美国的演讲稿急！！！！！真急！！！！！！

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 its 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, or insular areas, scattered around the Caribbean and Pacific.

At 3.79 million square miles (9.83 million km²) and with about 305 million people, the United States is the third or fourth largest country by total area, and third largest by land area and by population. The United States is one of the world's most ethnically diverse and multicultural nations, the proct of large-scale immigration from many countries. The U.S. economy is the largest national economy in the world, with an estimated 2008 gross domestic proct (GDP) of US$14.3 trillion (23% of the world total based on nominal GDP and almost 21% at purchasing power parity).

The nation was founded by thirteen colonies of Great Britain located along the Atlantic seaboard. On July 4, 1776, they issued the Declaration of Independence, which proclaimed their independence from Great Britain and their formation of a cooperative union. The rebellious states defeated Great Britain in the American Revolutionary War, the first successful colonial war of independence. A federal 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 instrial 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. The Spanish–American War and World War I confirmed the country's status as a military power. In 1945, the United States emerged from World War II as the first country with nuclear weapons, a permanent member of the United Nations Security Council, and a founding member of NATO. The end of the Cold War left the United States as the sole superpower. The country accounts for approximately 50% of global military spending and is a leading economic, political, and cultural force in the world.
美利坚合众国（通常被称为美国，在美国，在美国，或美国）是一个由五十个州和一个联邦区的联邦宪法共和国。该国大部分位于北美洲中部，其连续四十八个州和首都华盛顿特区，区，太平洋和大西洋之间的谎言，加拿大北部和墨西哥南部接壤。阿拉斯加的状态是在大陆的西北部，与加拿大的东部和俄罗斯横跨白令海峡以西。夏威夷州是在中太平洋群岛。该国还拥有多个地区，或岛屿地区，加勒比和太平洋周围散落。

在379万平方英里（9.83万美元平方公里），约305万人，美国是第三或第四大国，总面积和最大的土地面积和人口的三分之一。美国是世界上种族最多样化和多文化的国家之一，从许多国家的大规模移民的产品。美国经济是世界上最大的国民经济，估计2008年的总国内生产总值（GDP）美元的14.3万亿美元（按购买力平价计算的名义国内生产总值和近21％的世界总量的23％）。

国家成立由位于大西洋海岸沿线的13个大不列颠殖民地。1776年7月4日，他们发表“独立宣言”，宣布从大不列颠及他们形成合作联盟的独立性。反叛的状态击败大不列颠在美国革命战争，第一次成功的殖民地的独立战争。一位联邦大会通过了关于1787年9月17日，目前美国宪法，其批准，次年，美国与一个强大的中央政府的单一共和国的一部分。由十个宪法修正案，许多基本的公民权利和自由的保障，人权法案，在1791年被批准。

美国在19世纪，从法国，西班牙，英国，墨西哥，俄罗斯和收购土地，并吞并了得克萨斯州和夏威夷共和国共和国。南方和北方工业土地超过国家的权利和奴隶制度的扩张之间的纠纷引起了19世纪60年代的美国内战。北方的胜利，阻止了该国的永久分裂，导致在美国法律上的奴隶制结束。由19世纪70年代，国家的经济是世界上最大的。美西战争和第一次世界大战证实国家作为一个军事大国的地位。1945年，美国从第二次世界大战涌现出的第一个国家拥有核武器，联合国安理会常任理事国，北约的创始成员。冷战结束后离开美国作为唯一的超级大国。该国占全球军费开支约50％，是一家领先的经济，政治和文化在世界的力量。

⑷ 美国励志人物大学演讲稿中英文对照版，有哪些

Madam President Faust, members of the Harvard Corporation and the Board of Overseers, faculty, family, friends, and, most importantly, today's graates,
尊敬的Faust校长，哈佛集团的各位成员，监管理事会的各位理事，各位老师，各位家长，各位朋友，以及最重要的各位毕业生同学，

Thank you for letting me share this wonderful day with you.
感谢你们，让我有机会同你们一起分享这个美妙的日子。

I am not sure I can live up to the high standards of Harvard Commencement speakers. Last year, J.K. Rowling, the billionaire novelist, who started as a classics student, graced this podium. The year before, Bill Gates, the mega-billionaire philanthropist and computer nerd stood here. Today, sadly, you have me. I am not a billionaire, but at least I am a nerd.
我不太肯定，自己够得上哈佛大学毕业典礼演讲人这样的殊荣。去年登上这个讲台的是，英国亿万身家的小说家J.K. Rowling女士，她最早是一个古典文学的学生。前年站在这里的是比尔•盖茨先生，他是一个超级富翁、一个慈善家和电脑高手。今年很遗憾，你们的演讲人是我，虽然我不是很有钱，但是至少我也算一个高手。

I am grateful to receive an honorary degree from Harvard, an honor that means more to me than you might care to imagine. You see, I was the academic black sheep of my family. My older brother has an M.D./Ph.D. from MIT and Harvard while my younger brother has a law degree from Harvard. When I was awarded a Nobel Prize, I thought my mother would be pleased. Not so. When I called her on the morning of the announcement, she replied, "That's nice, but when are you going to visit me next." Now, as the last brother with a degree from Harvard, maybe, at last, she will be satisfied.
我很感激哈佛大学给我荣誉学位，这对我很重要，也许比你们会想到的还要重要。要知道，在学术上，我是我们家的不肖之子。我的哥哥在麻省理工学院得到医学博士，在哈佛大学得到哲学博士；我的弟弟在哈佛大学得到一个法律学位。我本人得到诺贝尔奖的时候，我想我的妈妈会高兴。但是，我错了。消息公布的那天早上，我给她打电话，她听了只说："这是好消息，不过我想知道，你下次什么时候来看我？"如今在我们兄弟当中，我最终也拿到了哈佛学位，我想这一次，她会感到满意。

Another difficulty with giving a Harvard commencement address is that some of you may disapprove of the fact that I have borrowed material from previous speeches. I ask that you forgive me for two reasons.
在哈佛大学毕业典礼上发表演讲，还有一个难处，那就是你们中有些人可能有意见，不喜欢我重复前人演讲中说过的话。我要求你们谅解我，因为两个理由。

First, in order to have impact, it is important to deliver the same message more than once. In science, it is important to be the first person to make a discovery, but it is even more important to be the last person to make that discovery.
首先，为了产生影响力，很重要的方法就是重复传递同样的信息。在科学中，第一个发现者是重要的，但是在得到公认前，最后一个将这个发现重复做出来的人也许更重要。

Second, authors who borrow from others are following in the footsteps of the best. Ralph Waldo Emerson, who graated from Harvard at the age of 18, noted "All my best thoughts were stolen by the ancients." Picasso declared "Good artists borrow. Great artists steal." Why should commencement speakers be held to a higher standard?
其次，一个借鉴他人的作者，正走在一条前人开辟的最佳道路上。哈佛大学毕业生、诗人爱默生曾经写下："古人把我最好的一些思想都偷走了。"画家毕加索宣称"优秀的艺术家借鉴，伟大的艺术家偷窃。"那么为什么毕业典礼的演说者，就不适用同样的标准呢？

I also want to point out the irony of speaking to graates of an institution that would have rejected me, had I the chutzpah to apply. I am married to "Dean Jean," the former dean of admissions at Stanford. She assures me that she would have rejected me, if given the chance. When I showed her a draft of this speech, she objected strongly to my use of the word "rejected." She never rejected applicants; her letters stated that "we are unable to offer you admission." I have difficulty understanding the difference. After all, deans of admissions of highly selective schools are in reality, "deans of rejection." Clearly, I have a lot to learn about marketing.
我还要指出一点，向哈佛毕业生发表演说，对我来说是有讽刺意味的，因为如果当年我斗胆向哈佛大学递交入学申请，一定会被拒绝。我的妻子Jean当过斯坦福大学的招生主任，她向我保证，如果当年我申请斯坦福大学，她会拒绝我。我把这篇演讲的草稿给她过目，她强烈反对我使用"拒绝"这个词，她从来不拒绝任何申请者。在拒绝信中，她总是写："我们无法提供你入学机会。"我分不清两者到底有何差别。在我看来，那些大热门学校的招生主任与其称为"准许你入学的主任"，还不如称为"拒绝你入学的主任"。很显然，我需要好好学学怎么来推销自己。

My address will follow the classical sonata form of commencement addresses. The first movement, just presented, were light-hearted remarks. This next movement consists of unsolicited advice, which is rarely valued, seldom remembered, never followed. As Oscar Wilde said, "The only thing to do with good advice is to pass it on. It is never of any use to oneself." So, here comes the advice. First, every time you celebrate an achievement, be thankful to those who made it possible. Thank your parents and friends who supported you, thank your professors who were inspirational, and especially thank the other professors whose less-than-brilliant lectures forced you to teach yourself. Going forward, the ability to teach yourself is the hallmark of a great liberal arts ecation and will be the key to your success. To your fellow students who have added immeasurably to your ecation ring those late night discussions, hug them. Also, of course, thank Harvard. Should you forget, there's an alumni association to remind you. Second, in your future life, cultivate a generous spirit. In all negotiations, don't bargain for the last, little advantage. Leave the change on the table. In your collaborations, always remember that "credit" is not a conserved quantity. In a successful collaboration, everybody gets 90 percent of the credit.
毕业典礼演讲都遵循古典奏鸣曲的结构，我的演讲也不例外。刚才是第一乐章----轻快的闲谈。接下来的第二乐章是送上门的忠告。这样的忠告很少被重视，几乎注定被忘记，永远不会被实践。但是，就像王尔德说的："对于忠告，你所能做的，就是把它送给别人，因为它对你没有任何用处。"所以，下面就是我的忠告。第一，取得成就的时候，不要忘记前人。要感谢你的父母和支持你的朋友，要感谢那些启发过你的教授，尤其要感谢那些上不好课的教授，因为他们迫使你自学。从长远看，自学能力是优秀的文理教育中必不可少的，将成为你成功的关键。你还要去拥抱你的同学，感谢他们同你进行过的许多次彻夜长谈，这为你的教育带来了无法衡量的价值。当然，你还要感谢哈佛大学。不过即使你忘了这一点，校友会也会来提醒你。第二，在你们未来的人生中，做一个慷慨大方的人。在任何谈判中，都把最后一点点利益留给对方。不要把桌上的钱都拿走。在合作中，要牢记荣誉不是一个守恒的量。成功合作的任何一方，都应获得全部荣誉的90%。

Jimmy Stewart, as Elwood P. Dowd in the movie "Harvey" got it exactly right. He said: "Years ago my mother used to say to me, 'In this world, Elwood, you must be ... she always used to call me Elwood ... in this world, Elwood, you must be oh so smart or oh so pleasant.'" Well, for years I was smart. ... I recommend pleasant. You may quote me on that.
电影《Harvey》中，Jimmy Stewart扮演的角色Elwood P. Dowd，就完全理解这一点。他说："多年前，母亲曾经对我说，'Elwood，活在这个世界上，你要么做一个聪明人，要么做一个好人。'"我做聪明人，已经做了好多年了。......但是，我推荐你们做好人。你们可以引用我这句话。

My third piece of advice is as follows: As you begin this new stage of your lives, follow your passion. If you don't have a passion, don't be satisfied until you find one. Life is too short to go through it without caring deeply about something. When I was your age, I was incredibly single-minded in my goal to be a physicist. After college, I spent eight years as a graate student and postdoc at Berkeley, and then nine years at Bell Labs. During that my time, my central focus and professional joy was physics.
我的第三个忠告是，当你开始生活的新阶段时，请跟随你的爱好。如果你没有爱好，就去找，找不到就不罢休。生命太短暂，如果想有所成，你必须对某样东西倾注你的深情。我在你们这个年龄，是超级的一根筋，我的目标就是非成为物理学家不可。本科毕业后，我在加州大学伯克利分校又待了8年，读完了研究生，做完了博士后，然后去贝尔实验室待了9年。在这些年中，我关注的中心和职业上的全部乐趣，都来自物理学。

Here is my final piece of advice. Pursuing a personal passion is important, but it should not be your only goal. When you are old and gray, and look back on your life, you will want to be proud of what you have done. The source of that pride won't be the things you have acquired or the recognition you have received. It will be the lives you have touched and the difference you have made.
我还有最后一个忠告，就是说兴趣爱好固然重要，但是你不应该只考虑兴趣爱好。当你白发苍苍、垂垂老矣、回首人生时，你需要为自己做过的事感到自豪。你的物质生活和得到的承认，都不会产生自豪。只有那些你出手相助、被你改变过的人和事，才会让你产生自豪。

After nine years at Bell labs, I decided to leave that warm, cozy ivory tower for what I considered to be the "real world," a university. Bell Labs, to quote what was said about Mary Poppins, was "practically perfect in every way," but I wanted to leave behind something more than scientific articles. I wanted to teach and give birth to my own set of scientific children.
在贝尔实验室待了9年后，我决定离开这个温暖舒适的象牙塔，走进我眼中的"真实世界"----大学。我对贝尔实验室的看法，就像别人形容电影Mary Poppins的话，"实际上完美无缺"。但是，我想为世界留下更多的东西，不只是科学论文。我要去教书，培育我自己在科学上的后代。

Ted Geballe, a friend and distinguished colleague of mine at Stanford, who also went from Berkeley to Bell Labs to Stanford years earlier, described our motives best:
我在斯坦福大学有一个好友兼杰出同事Ted Geballe。他也是从伯克利分校去了贝尔实验室，几年前又离开贝尔实验室去了斯坦福大学。他对我们的动机做出了最佳描述：

"The best part of working at a university is the students. They come in fresh, enthusiastic, open to ideas, unscarred by the battles of life. They don't realize it, but they're the recipients of the best our society can offer. If a mind is ever free to be creative, that's the time. They come in believing textbooks are authoritative, but eventually they figure out that textbooks and professors don't know everything, and then they start to think on their own. Then, I begin learning from them."
"在大学工作，最大的优点就是学生。他们生机勃勃，充满热情，思想自由，还没被生活的重压改变。虽然他们自己没有意识到，但是他们是这个社会中你能找到的最佳受众。如果生命中曾经有过思想自由和充满创造力的时期，那么那个时期就是你在读大学。进校时，学生们对课本上的一字一句毫不怀疑，渐渐地，他们发现课本和教授并不是无所不知的，于是他们开始独立思考。从那时起，就是我开始向他们学习了。"

My students, post doctoral fellows, and the young researchers who worked with me at Bell Labs, Stanford, and Berkeley have been extraordinary. Over 30 former group members are now professors, many at the best research institutions in the world, including Harvard. I have learned much from them. Even now, in rare moments on weekends, the remaining members of my biophysics group meet with me in the ether world of cyberspace.
我教过的学生、带过的博士后、合作过的年轻同事，都非常优秀。他们中有30多人，现在已经是教授了。他们所在的研究机构有不少是全世界第一流的，其中就包括哈佛大学。我从他们身上学到了很多东西。即使现在，我偶尔还会周末上网，向现在还从事生物物理学研究的学生请教。

I began teaching with the idea of giving back; I received more than I gave. This brings me to the final movement of this speech. It begins with a story about an extraordinary scientific discovery and a new dilemma that it poses. It's a call to arms and about making a difference.
我怀着回报社会的想法，开始了教学生涯。我的一生中，得到的多于我付出的，所以我要回报社会。这就引出了这次演讲的最后一个乐章。首先我要讲一个了不起的科学发现，以及由此带来的新挑战。它是一个战斗的号令，到了做出改变的时候了。

⑸ 高分求美国十大著名演讲（要中英文对照地）

[中英文对照]名人演讲--I Have A Dream[马丁·路德·金]PS:这篇我也背过
马丁·路德·金（公元1929—1968年），美国黑人律师，著名黑人民权运动领袖。一生曾三次被捕，三次被行刺，1964年获诺贝尔和平奖。1968年被种族主义分子枪杀。他被誉为近百年来八大最具有说服力的演说家之一。1963年他领导25万人向华盛顿进军“大游行”，为黑人争取自由平等和就业。马丁·路德·金在游行集会上发表了这篇著名演说。

Five score years ago, a great American, in whose symbolic shadow we stand signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of captivity.
100年前，一位伟大的美国人——今天我们就站在他象征性的身影下——签署了《解放宣言》。这项重要法令的颁布，对于千百万灼烤于非正义残焰中的黑奴，犹如带来希望之光的硕大灯塔，恰似结束漫漫长夜禁锢的欢畅黎明。

But one hundred years later, we must face the tragic fact that the Negro is still not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languishing in the corners of American society and finds himself an exile in his own land. So we have come here today to dramatize an appalling condition.

然而，100年后，黑人依然没有获得自由。100年后，黑人依然悲惨地蹒跚于种族隔离和种族歧视的枷锁之下。100年后，黑人依然生活在物质繁荣翰海的贫困孤岛上。100年后，黑人依然在美国社会中间向隅而泣，依然感到自己在国土家园中流离漂泊。所以，我们今天来到这里，要把这骇人听闻的情况公诸于众。

In a sense we have come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men would be guaranteed the inalienable rights of life, liberty, and the pursuit of happiness.

从某种意义上说，我们来到国家的首都是为了兑现一张支票。我们共和国的缔造者在拟写宪法和独立宣言的辉煌篇章时，就签署了一张每一个美国人都能继承的期票。这张期票向所有人承诺——不论白人还是黑人——都享有不可让渡的生存权、自由权和追求幸福权。

It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check which has come back marked "insufficient funds." But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation.

然而，今天美国显然对她的有色公民拖欠着这张期票。美国没有承兑这笔神圣的债务，而是开始给黑人一张空头支票——一张盖着“资金不足”的印戳被退回的支票。但是，我们决不相信正义的银行会破产。我们决不相信这个国家巨大的机会宝库会资金不足。

So we have come to cash this check -- a check that will give us upon demand the riches of freedom and the security of justice.

因此，我们来兑现这张支票。这张支票将给我们以宝贵的自由和正义的保障。

We have also come to this hallowed spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of graalism. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to open the doors of opportunity to all of God's children. Now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood.
我们来到这块圣地还为了提醒美国：现在正是万分紧急的时刻。现在不是从容不迫悠然行事或服用渐进主义镇静剂的时候。现在是实现民主诺言的时候。现在是走出幽暗荒凉的种族隔离深谷，踏上种族平等的阳关大道的时候。现在是使我们国家走出种族不平等的流沙，踏上充满手足之情的磐石的时候。现在是使上帝所有孩子真正享有公正的时候。

It would be fatal for the nation to overlook the urgency of the moment and to underestimate the determination of the Negro. This sweltering summer of the Negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. Nineteen sixty-three is not an end, but a beginning
忽视这一时刻的紧迫性，对于国家将会是致命的。自由平等的朗朗秋日不到来，黑人顺情合理哀怨的酷暑就不会过去。1963年不是一个结束，而是一个开端。

Those who hope that the Negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to business as usual. There will be neither rest nor tranquility in America until the Negro is granted his citizenship rights. The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.
如果国家依然我行我素，那些希望黑人只需出出气就会心满意足的人将大失所望。在黑人得到公民权之前，美国既不会安宁，也不会平静。反抗的旋风将继续震撼我们国家的基石，直至光辉灿烂的正义之日来临。

But there is something that I must say to my people who stand on the warm threshold which leads into the palace of justice. In the process of gaining our rightful place we must not be guilty of wrongful deeds. Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.
但是，对于站在通向正义之宫艰险门槛上的人们，有一些话我必须要说。在我们争取合法地位的过程中，切不要错误行事导致犯罪。我们切不要吞饮仇恨辛酸的苦酒，来解除对于自由的饮渴。

We must forever conct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again we must rise to the majestic heights of meeting physical force with soul force.
我们应该永远得体地、纪律严明地进行斗争。我们不能容许我们富有创造性的抗议沦为暴力行动。我们应该不断升华到用灵魂力量对付肉体力量的崇高境界。

The marvelous new militancy which has engulfed the Negro community must not lead us to distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny and their freedom is inextricably bound to our freedom.
席卷黑人社会的新的奇迹般的战斗精神，不应导致我们对所有白人的不信任——因为许多白人兄弟已经认识到：他们的命运同我们的命运紧密相连，他们的自由同我们的自由休戚相关。他们今天来到这里参加集会就是明证。

We cannot walk alone.And as we walk, we must make the pledge that we shall march ahead. We cannot turn back. There are those who are asking the devotees of civil rights, "When will you be satisfied?" We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as the Negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote. No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.
我们不能单独行动。当我们行动时，我们必须保证勇往直前。我们不能后退。有人问热心民权运动的人：“你们什么时候会感到满意？”只要黑人依然是不堪形容的警察暴行恐怖的牺牲品，我们就决不会满意。只要我们在旅途劳顿后，却被公路旁汽车游客旅社和城市旅馆拒之门外，我们就决不会满意。只要黑人的基本活动范围只限于从狭小的黑人居住区到较大的黑人居住区，我们就决不会满意。只要我们的孩子被“仅供白人”的牌子剥夺个性，损毁尊严，我们就决不会满意。只要密西西比州的黑人不能参加选举，纽约州的黑人认为他们与选举毫不相干，我们就决不会满意。不，不，我们不会满意，直至公正似水奔流，正义如泉喷涌。

I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow cells. Some of you have come from areas where your quest for freedom left you battered by the storms of persecution and staggered by the winds of police brutality. You have been the veterans of creative suffering. Continue to work with the faith that unearned suffering is redemptive.
我并非没有注意到你们有些人历尽艰难困苦来到这里。你们有些人刚刚走出狭小的牢房。有些人来自因追求自由而遭受迫害风暴袭击和警察暴虐狂飙摧残的地区。你们饱经风霜，历尽苦难。继续努力吧，要相信：无辜受苦终得拯救。

Go back to Mississippi, go back to Alabama, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed. Let us not wallow in the valley of despair.
回到密西西比去吧；回到亚拉巴马去吧；回到南卡罗来纳去吧；回到佐治亚去吧；回到路易斯安那去吧；回到我们北方城市中的贫民窟和黑人居住区去吧。要知道，这种情况能够而且将会改变。我们切不要在绝望的深渊里沉沦。

I say to you today, my friends, that in spite of the difficulties and frustrations of the moment, I still have a dream. It is a dream deeply rooted in the American dream.
朋友们，今天我要对你们说，尽管眼下困难重重，但我依然怀有一个梦。这个梦深深植根于美国梦之中。

I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal."
我梦想有一天，这个国家将会奋起，实现其立国信条的真谛：“我们认为这些真理不言而喻：人人生而平等。”

I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slaveowners will be able to sit down together at a table of brotherhood.
我梦想有一天，在佐治亚州的红色山岗上，昔日奴隶的儿子能够同昔日奴隶主的儿子同席而坐，亲如手足。

I have a dream that one day even the state of Mississippi, a desert state, sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice.
我梦想有一天，甚至连密西西比州——一个非正义和压迫的热浪逼人的荒漠之州，也会改造成为自由和公正的青青绿洲。

I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
我梦想有一天，我的四个小女儿将生活在一个不是以皮肤的颜色，而是以品格的优劣作为评判标准的国家里。

I have a dream today.
我今天怀有一个梦。

I have a dream that one day the state of Alabama, whose governor's lips are presently dripping with the words of interposition and nullification, will be transformed into a situation where little black boys and black girls will be able to join hands with little white boys and white girls and walk together as sisters and brothers.
我梦想有一天，亚拉巴马州会有所改变——尽管该州州长现在仍滔滔不绝地说什么要对联邦法令提出异议和拒绝执行——在那里，黑人儿童能够和白人儿童兄弟姐妹般地携手并行。

I have a dream today.
我今天怀有一个梦。

I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.
我梦想有一天，深谷弥合，高山夷平，歧路化坦途，曲径成通衢，上帝的光华再现，普天下生灵共谒。

This is our hope. This is the faith with which I return to the South. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.
这是我们的希望。这是我将带回南方去的信念。有了这个信念，我们就能绝望之山开采出希望之石。有了这个信念，我们就能把这个国家的嘈杂刺耳的争吵声，变为充满手足之情的悦耳交响曲。有了这个信念，我们就能一同工作，一同祈祷，一同斗争，一同入狱，一同维护自由，因为我们知道，我们终有一天会获得自由。

This will be the day when all of God's children will be able to sing with a new meaning, "My country, 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim's pride, from every mountainside, let freedom ring."
从到了这一天，上帝的所有孩子都能以新的含义高唱这首歌：我的祖国，可爱的自由之邦，我为您歌唱。这是我祖先终老的地方，这是早期移民自豪的地方，让自由之声，响彻每一座山岗。

And if America is to be a great nation this must become true. So let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania!
Let freedom ring from the snowcapped Rockies of Colorado!
Let freedom ring from the curvaceous peaks of California!
But not only that; let freedom ring from Stone Mountain of Georgia!
Let freedom ring from Lookout Mountain of Tennessee!
Let freedom ring from every hill and every molehill of Mississippi. From every mountainside, let freedom ring.
如果美国要成为伟大的国家，这一点必须实现。因此，让自由之声响彻新罕布什尔州的巍峨高峰！
让自由之声响彻纽约州的崇山峻岭！
让自由之声响彻宾夕法尼亚州的阿勒格尼高峰！
让自由之声响彻科罗拉多州冰雪皑皑的洛基山！
让自由之声响彻加利福尼亚州的婀娜群峰！
不，不仅如此；让自由之声响彻佐治亚州的石山！
让自由之声响彻田纳西州的望山！
让自由之声响彻密西西比州的一座座山峰，一个个土丘！
让自由之声响彻每一个山岗！

When we let freedom ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual, "Free at last! free at last! thank God Almighty, we are free at last!"
当我们让自由之声轰响，当我们让自由之声响彻每一个大村小庄，每一个州府城镇，我们就能加速这一天的到来。那时，上帝的所有孩子，黑人和白人，犹太教徒和非犹太教徒，耶稣教徒和天主教徒，将能携手同唱那首古老的黑人灵歌：“终于自由了！终于自由了！感谢全能的上帝，我们终于自由了！”

一：最后一片叶子
朋友们： 读过美国著名作家欧·亨利小说《最后一片叶子》的人，想必还记得这句话：“当最后一片叶子落下时，生命就都结束了，我也得离开这个世界而去了。…酷爱生活的女画家约翰西，患了肺炎濒临大限时，“害怕在她轻轻抓着这个世界的手越来越乏力的时候，她会真的像一片轻轻的、纤弱的叶子那样，随深秋的寒凤飘逝而去”。初读这篇小说时，少年不识愁滋味，对主人公那仿佛病态的痴语我并不以为然，而正是在人类对绿色顶礼膜拜，绿色食品，绿色能源、绿色电脑、绿色冰箱，绿色建筑被人们广为崇尚的今天，重读小说《最后一片叶子》，才感悟到，这分明是一个寓言故事，约翰西的心语，分明是谷世之言，大籁希声。 就在欧·亨利自己的国家美利坚合众国的土地上，不是就有过深刻的历史教训吗？著名总统罗斯福对梅花鹿可谓情有独钟，从这点小小的总统私人利益出发，他便下令对北利亚桑纳州一片茂密的大森林进行大规模扫荡，大批鹿的天敌----狮子、狼等食肉动物被捕杀殆尽。四千多只鹿于是生物爆炸一般，呈几何级数迅猛增长，十几万只伸特长脖子的可爱精灵们，吃光了树上的叶子，仿佛只在转眼问，著名的大森林就从地球上消失了，最后剩下的，只有凡头病鹿。 鲁迅先生说过，悲剧是把美好的东西毁灭给人看。 在我省南部，有一个美丽的地方，她向来就被人们称为镶嵌在我们这个植物王国皇冠上的一颗绿宝石。她的美丽，当然是绿色赋予的。可是，就在这绿宝石之上，有8家红砖厂的大烟囱，不分昼夜地喷吐着氟化物和二氧化硫严重超标的浓烟，致使1262亩的天然橡胶林受害，三万零五百株橡胶树为之枯死，胶民们虽然怨气沸腾，却眼睁睁地奈何不了它，无独有偶，在同一纬度的广西某地，也上演过惊人相似的一幕，如果说那一幕还有点不同的话，就是红砖厂的废气除了使大面积胶林枯死外，还造成50多亩芒果只开花不结果，出现果荒。我们知道，天然橡胶是目前地球上极为少有的自然资源，仅生长在赤过附近，我们也知道，芒果是公认的“水果之王”，那么何以会出现上面那样的情况呢？----因为红泥巴变成砖块，只需要几天的时间，远比橡胶芒果来钱要快！ 绿色是和平和生命的象征。在很小的时候，我的心便融进了一个绿色的海洋。穿了十凡年国防绿的我，在老山战区那片阳光充足，绿色位浓的亚热带丛林中，度过了人生位美好的一段年华。就是在那样一个空气、阳光、风雨充足的天然大氧吧里，我步入了而立之年。此生最难忘的，能维系裁生命的，大概就只有那特殊的一片绿色了。而事实上，那片我魂牵梦紫的土地至今还不富裕，一些地方生产力水平低下，社会发育程度不高，边民的农事，至今还离不开刀耕火种，纵火烧荒。我曾目赌过两个边民合伙买一盒火柴平分的事，开始想当然地以为他们太穷，买不起一盒囫囵的火柴，后来才发现，在他们的生活里，四季灶膛火不断，一根火柴烧一年，大树小树变成灰。我能给他们的，就是一个毫无用处的忠告：可别把咱的林子都烧光了呀。 我的一个同事的办公桌上，摆着个木制的水杯，是什么木呢？红豆衫。昆明植物研究所的专家们，从世界珍稀植物红豆杉树皮里，提出了炖度达99.9% 以上的抗癌新药紫杉醇，可没料到的是随后发生的事，竟会令这些专家们痛心疾首，老泪纵横，滇东北相当数量的红豆杉被人剥光了树皮，砍光了枝叶，连树根也被拔走。因为一个商业秘密被公开，1克紫杉醇在国际上可卖到1万美元，那些人还相信一个神话，红豆杉做成的水杯、容忍，甚至根雕可以防癌。 在99昆明世博会期间，谈论这样沉重的话题，或许不大会时宜。知我者谓我心忧，不知我者谓我何求？我们知道，当今世界性的十大环境问题，即气候变暖、臭氧层破坏、生物多样性减少、酸雨蔓延、森林锐减、土地荒漠化，大气污染等，这其中就有9项是因绿色植被遇破坏直接导致的。楼房越益越高，生活越来越好，绿色却越来越少，越来越远，有感于此，我曾写下过这样的诗句：烟囱长成了森林／钢筋和混凝土切断了视线／我的瞳孔里就再没有了绿色／那天空的湛蓝呢／那海水的碧绿呢／那河流的清亮呢／那空气的爽朗呢。 人类只有一个地球，我们对这个星球上的生态系统有着永远摆脱不究的依赖性，需要地球源源不断地提供植物和动物的食物，需要有足够厚度的大气层，来保护人类不受过高成过低气温，以及过量紫外线的伤害，需要地球提供足够量的水和氧气来维持生命的存在，而没有了绿色，这一切岂不成了无本之源，好比毛长在皮子上，没有了皮，毛又咋生根？ 绿色锐减，吞噬绿色的，正是人类自己，是人类发展模式中那种对自然资源的掠夺性、破坏性开采。人类对绿色的无尽索取仍在威胁着生态平衡，破坏着生态的结构。据（一个保守的数字）统计，全世界每年有2000万公顷森林横遭盲目砍伐，这是5700个昆明市的面积啊。这已经造成了全球性的“温室效应”，与之相连，全世界每年有近5万个物种濒临灭绝，有近2700万公顷的农田蒙受沙漠化之灾，就连海底也日趋沙漠化，就不必再说那令我们痛心的去年在华夏大地发生长江、松嫩大灾了吧，也不必说我省的泥石流，山体滑坡了吧。如此盲目的行动如果得不到有效的制止和改变，势必爆发可怕的生态危机，而一旦它的爆发起出了人类控制的极限，其后果不堪想象。那时，我们都会明白，最后一片落叶将带走人类的命运，也决不是危言耸听。 我们欣喜地看到，可持续发展战略已经纳入了我目的政府行为，我国已颁布了10多部环境保护法， 200多项环境标准，绿化财政，正威为人们的自觉意识，“天人合一”．更是我们千年的愿望，我想我们应该叫响这样一个口号：绿色就是生产力！我省的金沙江等流域，炊坑代木兮，豆之河之干兮现象也已悄然消失。你可能问我，这一切还保不住你那最后一片叶子吗，那么，我要说的是，你还是去问问我们的《国歌》里，为什么至今还要唱“中华民族到了位危险的时候”这一句吧。诚然，正像我们的抗洪收灾能取得决定性胜利所昭示的那样，我们坚信，人类的本事能够挽狂澜于既倒,扶大厦之将倾，但是，常言说的好，人无远虑，必有近忧，居安思危，要防患于朱然。我们怎么能够等到头上见不到日月星辰，满目酸雨纷纷，脚下洪浪滔天，汪洋恣肆，人间无处不飞沙，等到“千山鸟飞绝，万径人踪灭”时，才悔不当初呢？ 聪明的作家欧·亨利是以其“欧·亨利式的结尾”著称于世的，那最后一片不凋的叶子，带来的是一个危亡病人的新生。我想，我们也会创造出另一个欧·享利式的结尾，迎来人类新生的。坐以待毙，从来就不是人类的选择，人类既已觉臣，就会在危机面前积极行动起来，把握历史机遇，化压力为动力，保卫绿色，保护我们共有的家圈。 面对现实，我们迎接挑战，展望未来，我们充满信心。
二：环境保护演讲稿

朋友们，你见过树吗？不，你见过的是街道两旁或公园里的树，单调、乏味、黑不溜秋。你见到水吗？不，你见过的是人工湖的水，浑浊、发臭、游人洗过脚的。你见过鸟吗？不，那是笼中之鸟，呆呆的、只会要吃的。 近年来，随着经济的发展、社会的进步，我国的环境也随之变化，大自然受到严重的破坏，如果我们还不行动起来，保护环境 ，那么在未来的某一天，我们顶会濒临动植物灭绝的死亡线上。 由于我国人口素质还不够高，对生态系统缺乏认识、不了解自然规律，近年来，我国的自然环境和生态平衡已经遭到严重的破坏。比如为取暖、做饭、盖房子大量破坏森林，进而造成水土流失、河道淤塞、洪水泛滥，由于城市无力供应干净能源，直接烧煤、烧柴造成空气污染，工厂用煤发电、没有对二氧化硫进行回收，造成空气中弥漫一氧化碳、二氧化硫粉末，出现酸雨损坏庄稼和建筑物的现象，由于城市垃圾、工厂废水来不及处理直接放入河道，使空气、水中及陆地上的生物受害造成生态不平衡，影响气候、影响人类健康生活条件，虽说我们国家地大物博，可是人均占有量占世界前列，这就要求我们对环境要做出适当的保护，我们即将跨入21世纪的大门 ，担当起主人的重任，我们能眼见着环境污染被破坏、而等闲视之吗？不，决不能，这就要求我们必须对环境做出适当的保护。 我们可以从身边一点一滴的小事做起，比如多植树造林，这就可以从根本上防止水土流失，爱护周围一草一木，不捕猎小动物等。但这些光凭我们的努力还不够，还要号召我们身边的每一个人为保护环境而做出贡献。 先辈陆蠡说：“绿色是多么宝贵啊！它是生命、是希望、是安慰、是快乐。”徐霞客也曾说 ，遍及高山大川，迎风沐雨，为的是“多识鸟兽虫鱼之名”。前辈先哲的体验，都告诉我们大自然环境不仅能陶冶人的情操，净化和抚慰人的心灵，而且有助于知识的积累和事业的成功。 朋友，当你受到“白天寂寞”和“黑夜孤独”煎熬的时候，当你陷入挫折和失意的时候，当你烦恼至及痛不欲生的时候，那么，你就走向大自然吧！那个时候你就会真正知道保护自然环境是何等重要。拥抱蓝天绿水，吻一吻泥土的芳香，在静静的山林中坐一坐，在绿色的草丛中坐一坐，顺手摘下一粒果子放在嘴里嚼一嚼，看看地上的蚂蚁不知疲倦的忙碌，都能使心绪渐渐平和，得到抚慰。你就会在大自然的真善美中，认识到你有你年轻的生命，你拥有一段生命的里程，激发你以丰富的知识和坚强的毅力去开拓一个美好的世界。
三：环境保护演讲稿
环保，一个熟悉得不能再熟悉的词，勿需解释，每个人都知道是什么意思。小时候我们都学过这样一首诗——“天苍苍，野茫茫，风吹草低见牛羊”，自此把我们带入对于美好的大自然风光的遐想中。那么的生机昂然、那么美丽和谐，每当接触到了自然中的一草一木，总有一丝丝的温暖与亲切漫过心田——我们美丽的家园
当时我们不会想到，随着社会的发展，人类在更广阔的范围内，以空前的规模改造着自然，创造史无前例的人间奇迹和物质文明的同时，我们的生存环境却遭到了破坏，大气、水、土地被严重污染，自然界的生态平衡受到严重的影响，湿地、酸雨、荒漠化、沙尘暴等字眼触目惊心。环境的这些变化，无一不威胁着人类的生存和发展。毫不夸张的说，爱护环境，保持生态的平衡，珍惜宝贵的自然资源，成了我们生存下去的要求。
然而，单单有了环保的意识是不够的，环保参与能力差，“光说不练”的还是占了大多数。作为一个青年人，我们已经投入社会主义建设的队伍中，可以说，污染就在我们眼前，而环保之路也正在我们的脚下。我们无权沉默，更无权冷面旁观！关注、了解是不够的，重在行动！在工作岗位我们必须自觉地维护环境卫生，做环境保护的主人。试想一下，如果我们每天节约一张纸，一杯水，一度电，长此以（投稿秘书家园，赢得丰厚回报！http://www.mishuhome.com 欢迎您）往人人行动起来，积极起来，将是一个多么可观的数字啊。如果我们的认识不够，就少看几集连续剧，多读几本关于环保知识的书藉，我想其结果必会是终身受益的。如果我们已为人父母，可以从小陪养孩子们的安全环保意识，告诉他们“天下兴亡，匹夫有责——爱护环境，匹夫有责”！
我们该说的话还有很多很多，我们该做的事也有很多很多，让我们再次回忆我们的绿色，它同时象征着环境——生命——和平。请真正的关心保护我们赖以生存的家园，立刻将自己的承诺付诸行动，千万不要让地球上最后一滴水是我们人类自己的眼泪……

⑼ 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 proct 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 proct (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 reced 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 instrial 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.

⑽ 美国总统演讲为什么从来不看演讲稿

他们演讲时，就和我们闲聊天一样。他们的水平在那儿呢，而且美国人在各个学龄段内都有演讲课程的，因此，容他们是经过反复培训的。他们和播音员不一样，没有什么字幕的。你看当初美国黑人领袖马丁路德金在露天演讲，哪有什么稿子呀，但那么流畅，那么生动，那么激励人心。美国总统天生都是演说家，这是做总统的必备素质之一。
