TheMason-DixonLineCharlesMason&JeremiahDixon:1763-1767Mason-Dixonline梅森迪克森线是美国宾夕法尼亚州和马里兰州的分界线，也是南北战征之前美国的南北区域分界线。这条分界线是美国历史上文化和经济的分界线。其名称是为了纪念发现宾夕法尼亚和马里兰之间的地理分界线的18世纪的英格兰探险者JeremiahDixon和CharlesMason。这一地理名词在美国的电影，音乐和文学作品中常有提及。TopographyoftheSoutheastCharleston,SC:TheSouth’sFirstPortNewOrleans,LA:TheBigEasyTopographyoftheMidwestTheGreatLakesregioncontainsnotonlythefivemainlakesthemselves,butalsonumerousminorlakesandrivers,aswellasapproximately35,000islands.TheGreatLakesareacollectionoffreshwaterlakeslocatedineasternNorthAmerica,ontheCanada–UnitedStatesborder.ConsistingofLakesSuperior,Michigan,Huron,Erie,andOntario,theyformthelargestgroupoffreshwaterlakesonEarth.Theyaresometimesreferredtoasthe"ThirdCoast"bysomecitizensoftheUnitedStates.ChicagoSkyline:The“Second”City芝加哥

芝加哥是美国第三大城市，人们将这座城市称为“风城”（TheWindyCity）、“第二城”（TheSecondCity）、“芝城”（Chi-Town）、“世界屠猪城”（HogButcherfortheWorld）、“巨肩之城”（CityoftheBigShoulders）、“劳动之城”（TheCityThatWorks）。如此多的称呼指的都是一座城市——芝加哥（Chicago）。如今的芝加哥是美国非常受欢迎的旅游城市，芝加哥市也有很多著名的景点，如希尔斯大厦、林肯公园、林肯动物园、旧水塔、密歇根大街、海军码头等每年都会吸引众多的游客来此。如果您是篮球迷，自然不要忘记去芝加哥公牛队（ChicagoBulls）的主场联合中心球馆(UnitedCenter)一睹“飞人”迈克尔·乔丹（MichaelJordan）雕像的风采。TheGreatPlainsTopographyoftheWestLosAngeles:TheCityofAngels?Hollywood:CityofLostDreams(CapitolRecords)(国会唱片)(属于EMI百代唱片)BodiesofWater
