回复The city of Philadelphia is the largest city in Pennsylvania and the fifth most populous city in the United States[1]。It is colloquially referred to as Philly,and known as The City of Brotherly Love (from Greek:桅喂位伪未έ位蠁蔚喂伪,/fi。la。ˈdɛl。fɛj。a/,"brotherly love" from philos "loving" and adelphos "brother")。The 2005 U。S。Census estimated population of the city proper is 1。4 million。[2] Philadelphia is a major commercial,educational,and cultural center for the nation。The Philadelphia鈥揅amden鈥揥ilmington metropolitan area is the fifth-largest in the U。S。as of the 2006 estimate with a population of 5。8 million (fourth largest according to official 2000 census)。[3]During part of the 18th century,the city was the first capital and most populous city of the United States。At that time,it eclipsed Boston and New York City in political and social importance,with Benjamin Franklin taking a large role in Philadelphia's rise。The city was the geographic center of the 18th century thinking and activity that gave birth to the American Revolution and subsequent American democracy and independence。Geography[edit] TopographyA simulated-color satellite image of Philadelphia taken on NASA's Landsat 7 satellite。The Delaware River is visible in this shot。According to the United States Census Bureau,the city has a total area of 369。4 km² (142。6 mi²)。349。9 km² (135。1 mi²) of it is land and 19。6 km² (7。6 mi²) of it (5。29%) is water。Bodies of water include the Delaware River,Schuylkill River,Cobbs Creek,Wissahickon Creek,and Pennypack Creek。The lowest point in the city lies 10 feet above sea level near Fort Mifflin in Southwest Philadelphia at the convergence of the Delaware and Schuylkill Rivers。The highest point is in Chestnut Hill,at 432 feet above sea level,near Evergreen Place,just north and west of Evergreen Avenue。The counties adjacent to Philadelphia are Montgomery County to the north; Bucks County to the northeast; Burlington County,New Jersey to the east; Camden County,New Jersey to the southeast; Gloucester County,New Jersey to the south; and Delaware County to the west。[edit] ClimatePhiladelphia's climate falls in the humid subtropical climate zone,although it is the northernmost city in the United States that meets this classification。Because Philadelphia is on the far northern end of this climate zone,some of its outlying suburbs,especially to the north and west,are considered to fall in the humid continental zone。Summers are typically hot and muggy,fall and spring are generally mild,and winter is cold,although infrequently very cold。Precipitation is almost uniformly distributed throughout the year[7]。January lows average 23掳F (-5掳C) and highs average 38掳F (3掳C)。The lowest officially recorded temperature was -11掳F (-24掳C) on February 9,1934[8],but temperatures below 14掳F (-10掳C) occur only a few times a year。July lows average 67掳F (20掳C) and highs average 86掳 F (30掳C)[9],although heat waves see highs above 95掳F (35掳C) with the heat index running as high as 110掳F (43掳C)。The highest temperature on record was 106掳F (41掳C) on August 7,1918[10]。Early fall and late winter are generally driest,with February being the driest month with only 2。74 in (69。8 mm) of average precipitation。Snowfall is variable,with some winters bringing light snow and others bringing many significant snowstorms。It is common for the heavier snowfall to occur north and west of the city,where the climate is slightly colder。The average annual snowfall is 21 in (534 mm)。Rainfall is generally spread throughout the year,with eight to eleven wet days per month,[11] at an average annual rate of 42 in (1068 mm)。HistoryInformation in this article or section has not been verified against sources and may not be reliable。Please check for inaccuracies and modify as needed,citing the sources against which it was checked。Main article:History of PhiladelphiaBefore Europeans arrived,the Delaware (Lenape) Indian settlement of Shackamaxon was located along the Delaware River。Although the area lay within the bounds described in the 1632 Charter of Maryland,the Calvert family's influence never reached this far north,and the first European settlers were Swedes (see New Sweden),who called it Wiccacoa,and thirteen families from Krefeld,Germany,who settled in Germantown in 1683。A congregation was formed in 1646 on Tinicum Island by Swedish missionary John Campanius; in 1700,the group built Gloria Dei Church,also known as Old Swedes'。Philadelphia is one of the earliest examples of a planned city。Its rectilinear grid of streets鈥攏ow a commonplace feature of urban planning鈥攚as its most noteworthy innovation。The city was founded and developed in 1682 by William Penn,a Quaker。The city's name means "brotherly love" in Greek (桅喂位伪未έ位蠁蔚喂伪)。Penn hoped that the city,as the capital of his new colony founded on principles of freedom and religious tolerance,would be a model of this philosophy。During early immigration by Quakers and others,some "first purchasers" who got title to land in the city also received farmland outside the city。One of the notable features of Penn's plan for the city was the creation of five large squares,to provide open space for the city's residents。Penn described his city as a "Greene Countrie Town," highlighting its difference from densely-built cities like London。Most of the city's construction was brick or stone to prevent fires,like the great fire of 1666 that devastated London when William Penn resided there。United States Declaration of IndependencePhiladelphia was a major center of the independence movement during the American Revolutionary War。The Declaration of Independence and US Constitution were drafted here and signed in the city's Independence Hall。Tun Tavern in the city is traditionally regarded as the location where,in 1775,the United States Marine Corps was founded。During the American Revolutionary War Philadelphia's population was split between Loyalists and Patriots。When the British Army took the city in 1777 many Loyalists lined the streets and sang 'God Save the King'。Upon the retaking of the city for the American cause in 1778 it was the turn of the Patriot population to line the streets in celebration,especially as the population had suffered through a bitter winter with many of the provisions going to the British Army。The British left a mess,says historian Allan Nevins:鈥 The enemy had left the neatest,cleanest,best-built town in America shockingly dirty and unkempt,had destroyed public and private buildings,had cut down trees and fences,and had filled the streets and gutters with obstructions。In the outskirts and in Germantown were the marks of battle。Most of the fine old country seats surrounding the city had been destroyed--the British had fired seventeen in one day。New-piled mounds in Washington Square showed where the bodies of Continental soldiers,maltreated and starved in their prison by the brutal jailer Cunningham,had been roughly buried"。[4] 鈥 About 3000 Loyalists fled with the British; 45 Loyalists who remained behind were put on trial for treason for consorting with the enemy in wartime。Two were convicted,and hanged。For a time in the 18th century,Philadelphia was the largest city in the Americas north of Mexico City,and the fourth largest under the rule of the British crown (after London,Bristol,and Dublin)。In 1790,as the result of a compromise between a number of Southern congressmen and Alexander Hamilton,then Secretary of the Treasury,the seat of the United States Government was moved from Federal Hall in New York to Congress Hall in Philadelphia,before assuming its current site in Washington,DC。In exchange for locating a permanent capital on the banks of the Potomac,the congressmen agreed to support Hamilton's financial proposals。Philadelphia served as capital for a decade,until 1800,when the Capitol building in the new federal city of Washington,DC was opened。
