第一篇:介绍美国的英语作文The United States of America, also known as the United States, the U.S., the U.S.A., and America, is a country in North America that shares land borders with Canada and Mexico, and a sea border with Russia. Extending from the Atlantic Ocean to the Pacific Ocean, the United States is a federal republic, with its capital in Washington, D.C.The present-day continental United States has been inhabited for at least 15,000 years by indigenous tribes.[1] After European exploration and settlement in the 16th century, the English established their own colonies—and gained control of others that had been begun by other European nations—in the eastern portion of the continent in the 17th and early 18th centuries. On 4 July 1776, at war with Britain over fair governance, thirteen of these colonies declared their independence. In 1783, the war ended in British acceptance of the new nation. Since then, the country has more than quadrupled in size: it now consists of 50 states and one federal district; it also has numerous overseas territories.At over 3.7 million square miles (over 9.5 million km²), the U.S. is the third or fourth largest country by total area, depending on whether the disputed areas of China are included. It is the world's third most populous nation, with nearly 300 millionpeople.The United States has maintained a liberal democratic political system since it adopted its Articles of Confederation on 1 March 1781 and the Constitution, the Articles' replacement, on 17 September 1787. American military, economic, cultural, and political influence increased throughout the 20th century; with the collapse of the Soviet Union at the end of the Cold War, the nation emerged as the world's sole remaining superpower.[2] Today, it plays a major role in world affairs.The earliest known use of the name America is from 1507, when a globe and a large map created by the German cartographer Martin Waldseemüller in Saint-Die-des-Vosges described the combined continents of North and South America. Although the origin of the name is uncertain[3], the most widely held belief is that expressed in an accompanying book, Cosmographiae Introductio, which explains it as a feminized version of the Latin name of Italian explorer Amerigo Vespucci (Americus Vespucius); in Latin, the other continents' names were all feminine. Vespucci theorized, correctly, that Christopher Columbus, on reaching islands in the Caribbean Sea in 1492, had come not to India but to a "New World".The Americas were also known as Columbia, after Columbus, prompting the name District of Columbia for the land set aside as the U.S. capital. Columbia remained a popular name for the United States until the early 20th century, when it fell into relative disuse; but it is still used poetically and appears in various names and titles. A female personification of the country is also called Columbia; she is similar to Britannia.[4][5][6][7] Columbus Day, a holiday in the U.S. and other countries in the Americas commemorating Columbus' October 1492 landing.The term "united States of America" was first used officially in the Declaration of Independence, adopted on 4 July 1776. On 15 November 1777, the Second Continental Congreadopted the Articles of Confederation, the first of which stated "The Stile of this Confederacy shall be 'The United States of America.'"The adjectival and demonymic forms for the United States are American, a point of controversy among some.美利坚合众国,也被称为美国,美国,美国美国,是一个在北美国家,陆地边界与加拿大和墨西哥,和一个与俄罗斯的海上边界。
关于美国英文介绍1.Silicon Valley is an area that "located on the San Francisco, California, peninsula, radiates outward from Stanford University. It is contained by the San Francisco Bay on the east, the Santa Cruz Mountains on the west, and the Coast Range to the southeast. At the turn of the century, when fruit orchards predominated, the area was known as the Valley of Heart's Delight "as Carolyn E. Tajnai, manager of Stanford computer forum begins one of her Web-manuscript that is describing Silicon Valley history from some of WWW best personal viewpoint.About 40 years ago, Stanford University had some financial problems. The authorities of university tried to solve the problems by leasing part of the university land to high-tech companies for 99 years.Carolyn Tajna clarified this point of Stanford's history in more detail:" In the 1950's, the idea of building an industrial park arose. The university had plenty of land over 8,000 acres....but money was needed to finance the University's rapid postwar growth. The original bequest of his farm by Leland Stanford prohibited the sale of this land, but there was nothing to prevent its being leased. It turned out that long-term leases were just as attractive to industry as out right ownership; thus, the Stanford Industrial Park was founded. The goal was to create a center of high technology close to a cooperative university. It was a stroke of genius , and Terman, calling it ``our secret weapon,'' quickly suggested that leases be limited to high technology companies that might be beneficial to Stanford. In 1951 Varian Associates signed a lease, and in 1953 the company moved into the first building in the park. Eastman Kodak, General Electric, Preformed Line Products, Admiral Corporation, Shockley Transistor Laboratory of Beckman Instruments, Lockheed, Hewlett-Packard, and others followed soon after."2.The United States of America (The USA)is made up of 50 states,it has an area of9372614 square kilometers.Washington D.C is the capital of the USA.New York is the biggest city in the USA.The National Day of the USA is on July 4th,which is also the date of the countey's independence.The national anthem of the United States is"the star-spangled banner".The official language of the United States is English3.Indiana is the 19th U.S. state and is located in the Midwest region of the United States of America.

这一天,50个州采用了这份宪法,并普遍认为这一天是各个州联合在一起,成为了美利坚合众国中的一份子。
The United States of America is a constitutional federal republic, situated primarily in North America. It comprises 50 states and one federal district, and has several territories with differing degrees of affiliation. It is also referred to, with varying formality, as the United States, the U.S., the U.S.A., the U.S. of A., America, the States, or (poetically) Columbia.Since the mid-20th century, following World War II, the United States has emerged as a dominant global influence in economic, political, military, scientific, technological, and cultural affairs. Because of its influence, the U.S. is considered a superpower and, particularly after the Cold War, a hyperpower by some.The country celebrates its founding date as July 4, 1776, when the Second Continental Congress—representing thirteen British colonies—adopted the Declaration of Independence that rejected British authority in favor ofself-determination.The structure of the government was profoundly changed in 1789, when the states replaced the Articles of Confederation with the United States Constitution. The date on which each of the fifty states adopted the Constitution is typically regarded as the date that state "entered the Union" to become part of the United States.General Information on the USAThe United States consists of 50 states and Washington D.C. The last two States to join the Union were Alaska (49th) and Hawaii (50th). Both joined in 1959.Washington DC is a federal district under the authority of the U.S. Congress. Washington DC is represented in Congress by an elected, non-voting Delegate to the House of Representatives. Residents have been able to vote in presidential elections since 1961.Puerto Rico is a commonwealth associated with the United States. Puerto Ricans are U.S. citizens. Puerto Ricans do not vote in U.S. Presidential elections, but they do elect a non-voting commissioner to the U.S. House of Representatives.U.S. V irgin Islands - St. John, St. Croix, and St. Thomas is an unincorporated territory of the United States. Administered by the Office of Insular Affairs, U.S. Department of the Interior. Indigenous inhabitants are U.S. citizens, but do not vote in U.S. Presidential elections.Northern Mariana Islands is a commonwealth in political union with the United States. Self-governing with locally elected governor and legislature.American Samoa is a unincorporated territory of the United States.

Administered by the Office of Insular Affairs, U.S. Department of the Interior. Inhabitants are U.S. citizens, but do not vote in U.S. Presidential elections.Other Dependent Areas of the United States: Baker Island - Howland Island - Jarvis Island - Johnston Atoll - Kingman Reef - Midway Islands - Navassa Island - Palmyra Atoll - Wake IslandGeographyAmericans often speak of their country as one of several large regions. These regions are cultural units rather than governmental units - formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share.What makes one region different from another? Within several regions, language is used differently and there are strong dialects. There are also differences in outlook and attitude based on geography. A region's multicultural heritage as well as distinct demographic characteristics like age and occupation also make regions different and special.The United States is a varied land - of forests, deserts, mountains, high flat lands and fertile plains. The country lies mostly in the temperate zone but there is a very wide range of climate variations. The continental United States stretches 4,500 kilometers from the Atlantic Ocean on the east to the Pacific Ocean on the west. It borders Canada on the north and reaches south to Mexico and the Gulf of Mexico. The United States covers a total area of 9 million square kilometers (including Alaska and Hawaii). Alaska is the largest in area of the 50 states, and Texas isthe second largest.From the Appalachian Mountains in the East to the Rocky Mountains in the West, the center of the country is drained by the Mississippi and Missouri Rivers and their branches. The Mississippi is one of the world's great rivers; it was known to Native Americans as the "father of waters." Water from the source of its main branch, the Missouri River, flows about 6,400 kilometers from the northern Rocky Mountains to the mouth of the Mississippi in the Gulf of Mexico. On a topographic map of the United States, the mountains look like jagged masses, the plains like vast, open flat spaces, and the rivers like meandering threads. Today, highways, railways and transcontinental aircraft criss-cross the land, making travel easy. But only a few generations ago, the topographic features on the map represented great dangers and difficulties.Today's visitors, riding over a good road in the Cascade Mountains in the west coast states of Oregon and Washington, may see marks on the rocks made by ropes where pioneer settlers painfully lowered their horses and wagons down cliffs to reach the fertile river valley far below. In the Sierra Nevada Mountains of California, the main route now runs through a mountain pass which was once too narrow for a wagon to go through. Pioneer families reaching that pass had to take their wagons apart piece by piece, carry them through, and then reassemble them on the other side. In 1848, pioneers who crossed the continent made the trip in 109 days - if they were fortunate and strong. Today a New Y ork family can drive by car to San Francisco in less than a week.HistoryThe first Europeans to reach North America were Icelandic V ikings, led by Leif Ericson, about the year 1000. Traces of their visit have been found in the Canadian province of Newfoundland, but the V ikings failed to establish a permanent settlement and soon lost contact with the new continent.Five centuries later, the demand for Asian spices, textiles, and dyes spurred European navigators to dream of shorter routes between East and West. Acting on behalf of the Spanish crown, in 1492 the Italian navigator Christopher Columbus sailed west from Europe and landed on one of the Bahama Islands in the Caribbean Sea. Within 40 years, Spanish adventurers had carved out a huge empire in Central and South America. In the 16th and 17th Century, Northern Europeans settled in what is now the North East Coast of the United States, which soon fell under the British Crown and stayed an English Colony till the Revolutionary Wars in the late 18th Century. Please see links below for an outline of the history of the United States, with a few selected focus areas.Government OverviewThe United States is a federal union of 50 states, with the District of Columbia as the seat of the federal government. The Constitution outlines the structure of the national government and specifies its powers and activities, and defines the relationship between the national government and individual state governments. Power is shared between the national and state (local) governments. Within each state are counties, townships, cities and villages, each of which has its own elective government.Governmental power and functions in the United States rest in three branches of government: the legislative, judicial, and executive. Article 1 of the Constitution defines the legislative branch and vests power to legislate in the Congress of the United States. The executive powers of the President are defined in Article 2. Article 3 places judicial power in the hands of one Supreme Court and inferior courts as Congress sees necessary to establish. In this system of a "separation of powers" each branch operates independently of the others, however, there are builtin "checks and balances" to prevent a concentration of power in any one branch and to protect the rights and liberties of citizens. For example, the President can veto bills approved by Congress and the President nominates individuals to serve in the Federal judiciary; the Supreme Court can declare a law enacted by Congress or an action by the President unconstitutional; and Congress can impeach the President and Federal court justices and judges.EconomyThe United S tates entered the 21st century with an economy that was bigger, and by many measures more successful, than ever. Though the United States held less than 5 percent of the world's population, it accounted for more than 25 percent of the world's economic output. In the 1990s, the American economy recorded the longest uninterrupted period of expansion in its history. A wave of technological innovations in computing, telecommunications, and the biological sciences were profoundly affecting how Americans work and play.The United States remains a "market economy." Americans continue to believe that an economy generally operates best when decisions about what to produce and what prices to charge for goods are made through the give-and-take of millions of independent buyers and sellers, not by government or by powerful private interests.Besides believing that free markets promote economic efficiency, Americans see them as a way of promoting their political values as well -- especially, their commitment to individual freedom and political pluralism and their opposition to undue concentrations of power. The American belief in "free enterprise" has not precluded a major role for government, however. Americans at times have looked to government to break up or regulate companies. that appeared to be developing so much power that they could defy market forces. They have relied on government to address matters the private economy overlooks, from education to protecting the environment. And despite their advocacy of market principles, they have used government at times to nurture new industries, and at times even to protect American companies from competition.。
美国文化,从某种意义上说,是欧洲文化的延伸,因为美国人的语言、她的人口构成,以及她的立国精神都源于欧洲。
另一方面,美国文化又与欧洲不同,因为欧洲移民在北美大陆上驱赶走印第安人后,在一片荒芜旷野之地创造了令人赞叹不已的灿烂文明。
所以,在谈论美国文化习俗与社交礼义时,既要顾及欧美文化的相同性,又要注意两者的相异性。
文化习俗是个范围广泛、内容复杂的题目,涉及人在社会生活和交往中的方方面面。
笔者拟定以杂谈的形式,就美国人的文化习俗作一粗浅概述。
宽容性美国是个移民之国,它的祖先来自于全球各地。
人们移居美国时,不仅仅在地理位置上挪动一下,而且还把他们所在国的评议和风俗习惯带到了新的居住地。
因为杂,人们各自的差异十分突出;因为差异十分普遍,人们就不特别注重统一性。
久而久之,美国人的文化习俗中形成了较高程度的宽容性(tolerance),对异质文化和不同评议持容忍、可接受的态度。
在这一点上,美国社会里可行的习俗要比世界上其他国家来得宽泛。
从政治上讲,这种宽容性表现在对自由的追求和对自由权利的维护。
从宗教上说,它体现在不同信仰的和谐共存。
从生活范围上看,它显现在不同和族、不同族裔社区的平安相处。
一言以蔽之,在美国,每个人基本上可以任意选择不同的观念、信仰、生活方式和传统习惯;人们也可以在相当程度上保持自己的习俗和仪。
譬如,犹太人可以庆祝他们的宗教节日,而基督教徒则能够他们的圣诞节和复活节。
再譬如,美国华人可以在唐人街用华语生活和工作;同样的道理,越南移民能够在他们的“小西贡”按越南的方式经营业务,从事各种活动。
美国人的容忍性,除了上面的美国是个移民国这个因素以外,还与美国人的频繁迁徙有关。
众所周知,美国历史发展中的一个重要部分是她的西部开发史。
那时,美国拓荒者或徒步跋涉,或骑马坐车,从东到西,从南到北,哪里有机遇,就往那里移居。
频繁的迁移和不断地更换居处使人们始终处于“流动”状态,对暂面临的种种不同现象更易于宽容和接受。

美国最高法院中英文介绍 美国联邦最高法院是美国最高审判机构,由总统征得参议院同意后任命的9名终身法官组成,其判例对全国有拘束力,享有特殊的司法审查(judicial review)权,即有权通过具体案例宣布联邦或各州的法律是否违宪。
The Supreme CourtThe Highest Judicial Authority最高法院最高司法机关 The Supreme Court is comprised of nine justices who are appointed to the bench for life, or until voluntary retirement. They are appointed by the President and must be confirmed by the U.S. Senate. A Case's Path to the Supreme Court While the Supreme Court may choose to hear cases directly, it most often selects cases that have been decided in lower courts. Participants in cases decided in lower courts can appeal to their state's highest or Supreme Court. If all state venues are exhausted, litigants may appeal to the United States Supreme Court, the highest court in this country. Some cases may begin in federal courts at the start3 , and these can also end up here. The nine justices choose which cases to take from those submitted to the Supreme Court. They can refuse to consider a case, accept a case for oral argument, or decide the case summarily without a hearing4. Each of these routes has an effect on the law. the decision not to hear a case allows a lower court's ruling to stand as precedent, or guiding law for other states. The court often decides that a case should be heard in circumstances in which two or more lower courts have decided differently. This split in the opinions of lower courts is common in highly charged issues. In this circumstance, the。
