9、ints,however,skylines dont stay the same forever.They change,sometimes slowly and sometimes suddenly.New York City is a great example of a place whose skyline has seen both slow and rapid change.In recent years,New Yorks skyline has changed dramatically.Buildings and structures have risen,fallen,and

10、 risen again.LondonParisNew YorkA New Skyline Level T56Growing the Big AppleNew York City was first settled in the seventeenth century.During the nineteenth century,its population exploded.The end of the Civil War brought freed slaves from the South in search of work.Later,waves of Europeans immigra

11、ted to the United States through the port of New York.Many of them stayed on New Yorks Manhattan Island.By the late 1800s,New York was the most densely populated city in the country.By 1925,it was the most densely populated city in the world.People needed places to live,work,and shop.The city grew n

12、orthward as more stores,factories,and homes were built.However,Manhattan Island is only about 23 square miles(59.6 sq km)in area.Soon there was nowhere left to build.The only place to grow was up.To do that,different building methods had to be used.Old methods had always used walls to support a buil

13、dings weight.The walls on the ground floor had to be strong enough to support the floors and roof above them.This requirement limited a buildings height.There was no practical way to make walls thick and strong enough to support a building with many floors.A new method involved using a steel frame i

14、nstead of walls to support the structure.Huge steel beams were connected to form the buildings skeleton.Then the walls were hung from the beams and attached at the bottom to the floor.The walls of the buildings upper floors did not weigh heavily on the lower floors walls.The steel frame beams held t

15、hem up.Steel frame construction made it possible for buildings to reach new heights.By the turn of the twentieth century,New York City was home to many huge structures called skyscrapers.Soon skyscrapers were going up one after another as builders and architects competed to make the worlds tallest b

16、uilding.An 1884 illustration of Lower Manhattan Island shows how little of the citys skyline had grown at that time.A New Skyline Level T78Building an EmpireIn 1928,the builder of the seventy-seven-story Chrysler Building wanted to make it the worlds tallest.The builder attached a tall spire onto th

17、e top of his structure.In 1930,the Chrysler Building became the worlds tallest structure.It also became the only building to stand taller than 1,000 feet(305 m).The Chrysler Buildings reign would not last.Just blocks away,a giant was rising.The Empire State Building was soon the worlds tallest,and w

22、g for nearly forty years,until twin giants rose from Lower Manhattan.Twin Giants Rise,Then FallAfter the Empire State Building was completed,skyscraper construction slowed down.Giant structures cost a lot to build,and the American economy was not doing well.It was not until 1970 that the citys skyli

23、ne would grow even higher.In the 1960s,city officials decided to build a center for international commerce in Lower Manhattan.The Port Authority of New York and New Jersey was in charge of this new“world trade center.”Architect Minoru Yamasaki designed the buildings.He proposed twin towers as part o

24、f a multibuilding complex.The Port AuthorityThe Port Authority of New York and New Jersey is an organization formed in 1921.Its purpose was to develop and operate trade and transportation facilities in both New Jersey and New York City.The Port Authority still owns and manages much of the 16-acre(64

26、-story towers would include some structural innovations.One was the use of tube-frame construction.Each tower was similar to a hollow square pipe.Along the outside walls of the building were columns spaced close together.This reduced the need for inside support columns and created more usable floor

27、space inside.Another innovation was the use of sky lobbies.Skyscrapers need many elevators.Yamasaki proposed an elevator system modeled after the citys subway system.The towers had both express and local elevators,just as the subway had express and local trains.People could take an express elevator

28、straight to a sky lobby on the forty-fourth floor.Then theyd transfer to a local elevator that would stop at every floor above to get to their offices.This system was an efficient way to transport people vertically.It reduced the number of elevator shafts needed.Construction began in 1966 and took f

29、our years.The North Tower was completed in December 1970.It stood 1,727 feet(526 m)tall at the tip of its spire.A restaurant atop the building called Windows on the World offered diners a breathtaking view.The South Tower,reaching 1,362 feet(415 m)high,was finished seven months later.Beneath both bu

31、o Elisha Otis,this problem was fixed.Otis designed the first safety elevator in 1854.The elevators platform would fall only a few inches if the cable holding it broke.He also designed engines to power the elevator.Without a doubt,Otiss invention was necessary to the development of tall buildings.The

32、 next time youre in an elevator,theres a good chance youll see the name“Otis”somewhere inside!OtisOver 3,500 workers helped build the World Trade Centers twin towers during their peak of construction.A New Skyline Level T1314The Twin Towers were a striking addition to the citys skyline.For thirty ye

33、ars,the World Trade Center towers were the tallest buildings in New York.Then disaster struck.On the morning of September 11,2001,hijackers flew two passenger jets into the towers.Within an hour after the attack,the South Tower began to fall and crumble to the ground.The North Tower soon followed.Ne

36、Trade Center complex.One area was set aside as a memorial park for those who had lost their lives that day.The sites of the original buildings are now pools with cascading waterfalls.A memorial museum contains items from the old towers.On September 11,2001,terrorists flew two planes into the Twin To
