篇一:TheU.S.
What Makes America a World Power?
Class One No.29 Becky
The United States of America has been a democracy for about 200 years. But how did America grow into a powerful nation from a colonial country in only 200 years? In my opinion, there are 3 significant events which make America a world power.
As the country grew after The American Revolution, differences between 13 states became more obvious. Southern states had many farms that used slave labor, so they didn’t agree to abolish slavery system. While Northerners were against slavery system, Abraham Lincoln was one of them. The situation of half-slave and half-free won’t last too long before the Civil Ward broke out. In 1861, when Lincoln became the president of America, the South claimed the right to break from the United States and form its own Confederacy. In April 1861, President Lincoln was determined to stop the rebellion and kept the country united. He led the Northern states to have a war against the Southern states. To strengthen the army in 1862 President Lincoln issued the Homestead Act and Emancipation Proclamation that freed all slaves in the Confederate states and allowed African Americans into the Union Army. The war lasted for 4 years and Northern states defeated Southern states. American Civil War was the second bourgeois revolution in United States, which abolished Black Slavery System, settled the land issue. It maintained the country united, cleaned the road for capitalism development and laid a good foundation for its future to become a world powerful country. There was no denying that the Civil War was very important to the American development,just like Lincoln once said, “A house divided against itself cannot stand.”
The United States focused on developing its economy after the Civil War. Then the age of invention came. Thomas Edison invented the light bulb; Bell developed the telephone; George made the movie, etc. Only from 1860 to 1890, the government issued 440,000 patents. In this period stared with the invention of electricity, America lunched a technology revolution known as the “Second Industrial Revolution.” Electrical power gradually replaced steam power, which greatly improved the productivity and brought a new strong impetus to American economy development. The widely use of electricity and other inventions not only brought convenience to American’s life but also created immeasurable wealth for the society. More factories, steel mills, and railroads were built. Cities grew in size and number. Relying on its advanced science and technology, the United States surpassed the European powers rapidly in the late 19th century. In 1894, the U.S. industrial output ranked first in the world, becoming the economic world power, when the new country was only 118 years old.
When Americans were living in the shadow of The Great Depression, the Second World War broke out. At first the U.S. did not participate in the war. However, when the war spread in Europe and Asia, the U.S. government was busy in preparing for the war. In addition to strengthening the military and recruiting, the government also placed emphasis on manufacturing military supplies. In 1941, after the war of Britain the U.S. government, as a neutral country, promulgated The Lend-Lease and exported lots of military supplies. In the later 4 years, the U.S. lent 32.5 billion worth of goods to Britain and Soviet Union. As the market’s demand for military supplies increased, labor demand grew in America. Because of the Second World War, American industry recovered, the job market expanded to women and blacks, the employment rate has gradually increased. When other countries’ economic were being destroyed severely by the war, the U.S. was enjoying its economic recovery and developing rapidly. Thus, after the World War II the U.S. became the most powerful country and maintained its position until today. Therefore, the World War II had a great and profound effect on the economic development of America. There’s a saying: “if there were no wars, there would be no today’s America.”

篇五:中英文介绍美国
中英文介绍美国
美国[UnitedStates]正式名称美利坚合众国。
北美洲联邦共和国。领土包括美洲大陆中纬度地区48个连成一片的州、北美洲西北端的阿拉斯加州,以及太平洋中部的岛州夏威夷。面积:(包括五大湖)9,529,063平方千米。人口:约286,067,000(2001)。
首都:华盛顿特区。人口包括白人、非洲裔美国人、西班牙裔美国人、亚洲人、太平洋岛民、美洲印第安人(美洲土著)、爱斯基摩人及阿留申人。语言:英语(主要语言)、西班牙语。宗教:新教、天主教、犹太教和伊斯兰教。货币:美元。地形由山脉、平原、低地和沙漠构成。山脉包括阿巴拉契亚山脉、欧扎克山、落基山脉、喀斯喀特山脉和内华达山脉。最低点是加利福尼亚州的死谷。最高点是阿拉斯加山脉的麦金利山,而在美国本土,最高点则是惠特尼山。主要河流是密西西比河系、科罗拉多河、哥伦比亚河和格兰德河。五大湖、大盐湖和奥基乔比湖为几个最大的湖。美国是世界某些矿产的主要生产国,包括铜、银、锌、金、煤、石油和天然气;也是食品的主要输出国。制造业包括钢铁产品、化学制品、电子产品和纺织品。
其他重要行业为旅游业、奶制品业、畜牧业、渔业和木材加工业。美国是两院制共和国。总统为国家元首和政府首脑。数千年以前已有一些美洲印第安人定居在这块领土,他们可能是来自亚洲。16世纪欧洲人来此探险和定居,开始取代印第安人。第一个欧洲人永久居民点是由西班牙人于1565年在佛罗里达州建立的圣奥古斯丁,后来英国人在弗吉尼亚州詹姆斯敦(1607)、马萨诸塞州普里茅斯(1620)、马里兰州(1634)
和宾夕法尼亚州(1681)建立定居点。在卡罗来纳被授予英国贵族一年后,1664年英国人从荷兰人手中夺走纽约、新泽西和德拉瓦。英国人于1763年击败法国人(参阅法英北美殖民地争夺战[FrenchandIndianWar]),在政治上控制了13个殖民地。英国殖民政策引起的政治动乱,以美国独立战争(1775~1783)和《独立宣言》(1776)而告结束。美国在《邦联条例》(1781)下首次组织起来,终于通过宪法(1787)成为联邦共和国。随后确认了西至密西西比河的美国疆界,但并不包括西班牙的属地佛罗里达。通过1803年的路易斯安那购地,美国从法国人手中购得的土地使美国领土几乎增加一倍。美国在1812年战争中与英国开战,1819年从西班牙人手中夺得佛罗里达。1830年通过立法手段将美洲印第安人迁移到密西西比河以西的土地。19世纪中叶开始向西部扩张,特别是1848年在加利福尼亚州发现金矿以后(参阅淘金热[goldrush])。
美国在墨西哥战争(1846~1848)中取得的胜利,使后来的7个州(包括加利福尼亚和得克萨斯)的部分或全部领土并入美国。1846年美国与英国签订条约确立其西北部疆界,在1853年加兹登购地中又获得亚利桑那州南部的土地。后来南方蓄奴的种植园经济和北方自由的工业与农业经济之间存在的矛盾冲突使美国分裂,爆发了南北战争(1861~1865,参阅美国南北战争[AmericanCivilWar])。第十三条宪法修正案废除了奴隶制。重建时期(1865~1877)以后,美国经历了快速发展、都市化、工业开发和欧洲移民。1877年美国准许把印第安人保留地的土地分给个别部落成员,致使大片土地落入白人手中。到19世纪末,美国的外贸得到发展并获得海外领土,包括阿拉斯加、中途岛、夏威夷群岛、菲律宾群岛、波多黎各、关岛、威克岛、美属萨摩亚、巴拿马运河区和维尔京群岛。1917~1918年美国参加了第一次世界大战。1920年给予妇女选举权;1924年给予美洲印第安人公民权。1929年的股市崩溃导致大萧条。日本人偷袭珍珠港(1941-12-07)
之后美国加入第二次世界大战。美国在日本广岛投下第一颗原子弹(1945-08-06),在长崎投下第二颗原子弹(1945-08-09),导致这场战争结束,并使美国成为西方世界的领袖。美国参与了欧洲和日本的战后重建工作,但却陷入与苏联长达40年的冷战对抗。美国参加了朝鲜战争。1952年给予波多黎各自治地位。1954年宣布在美国学校中实行的种族隔离违反了美国宪法。1959年阿拉斯加和夏威夷成为美国的两个州。1964年国会通过《民权法》,并授权全面干预越南战争。20世纪60年代中至末期美国国内各地发生骚乱,包括种族暴乱和反战示威。1969年美国完成首次人类登陆月球。1973年美军全部撤出越南。在波斯湾战争(1991)中,美国领导联军攻打伊拉克。1992年派兵到索马里救援饥民。1995年和1999年加入北大西洋公约组织空袭前南斯拉夫的塞尔维亚军队。1998年W.J.克林顿总统成为第二个要被美国众议院弹劾的总统;1999年他被参议院宣布无罪。1999年巴拿马运河的管理移交给了巴拿马。2000年G.W.布什成为1888年以来尽管获得的选票略低于对手A.戈尔,但仍被总统选举团选为总统的第一人。2001年9月11日恐怖分子的攻击摧毁了世界贸易中心和五角大楼的部分建筑以后,美国以藏匿并拒绝引渡此次恐怖活动的策划嫌疑本·拉登为由,派兵向阿富汗的塔利班政府发动进攻。
