There was a time when New York City buildings were almost all the same height.
Today you can see buildings of different heights that seem to touch the sky. They are called skyscrapers(摩天大楼). They shape the famous New York City skyline.
It started about 90 years ago. It began like a race. This wasn't a race down the street or around a track(跑道). It was a race for the sky. Who was racing? Buildings were.
Their builders were actually racing to build the world's tallest skyscraper.
The race started slowly.
First came the Woolworth Building, in 1913. It rose 792 feet(英尺) on the southern side of the city. Then the race heated up.In1930, two skyscrapers were nearing completion. The Bank of Manhattan Building was finished first. It rose up to 927 feet into the sky. Builders were then putting a round roof（屋顶）on the top of the Chrysler Building. It rose up t0 925 feet. The Bank of Manhattan, two feet taller, seemed to be the winner.
A few weeks later, New Yorkers saw a strange sight（景象）.  The day that the Chrysler Building was to be completed, workers raised a shiny metal, spire（尖顶）through the top of the building, adding 121 feet to the building's height! At l,048 feet, the Chrysler Building was now the world's tallest.
But the race was not over.  A year later, in 1931, the Empire State Building became the new winner.At l,250 feet, it was the world's tallest building.
In 1973, even that record was broken. Builders finished the World Trade Center. At 1,368 feet high, it rose above all other buildings in New York City.
Time goes on. As technology improves, taller buildings are being built. The race is still on.
