TheMason-DixonLineCharlesMason&JeremiahDixon:1763-1767Mason-Dixonline梅森迪克森線是美國(guó)賓夕法尼亞州和馬里蘭州的分界線，也是南北戰(zhàn)征之前美國(guó)的南北區(qū)域分界線。這條分界線是美國(guó)歷史上文化和經(jīng)濟(jì)的分界線。其名稱是為了紀(jì)念發(fā)現(xiàn)賓夕法尼亞和馬里蘭之間的地理分界線的18世紀(jì)的英格蘭探險(xiǎn)者JeremiahDixon和CharlesMason。這一地理名詞在美國(guó)的電影，音樂和文學(xué)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

芝加哥是美國(guó)第三大城市，人們將這座城市稱為“風(fēng)城”（TheWindyCity）、“第二城”（TheSecondCity）、“芝城”（Chi-Town）、“世界屠豬城”（HogButcherfortheWorld）、“巨肩之城”（CityoftheBigShoulders）、“勞動(dòng)之城”（TheCityThatWorks）。如此多的稱呼指的都是一座城市——芝加哥（Chicago）。如今的芝加哥是美國(guó)非常受歡迎的旅游城市，芝加哥市也有很多著名的景點(diǎn)，如希爾斯大廈、林肯公園、林肯動(dòng)物園、舊水塔、密歇根大街、海軍碼頭等每年都會(huì)吸引眾多的游客來(lái)此。如果您是籃球迷，自然不要忘記去芝加哥公牛隊(duì)（ChicagoBulls）的主場(chǎng)聯(lián)合中心球館(UnitedCenter)一睹“飛人”邁克爾·喬丹（MichaelJordan）雕像的風(fēng)采。TheGreatPlainsTopographyoftheWestLosAngeles:TheCityofAngels?Hollywood:CityofLostDreams(CapitolRecords)(國(guó)會(huì)唱片)(屬于EMI百代唱片)BodiesofWater
