     This is undoubtedly one of the most recognizable buildings in the world. Weighing 7,000 tons, but

putting about the same pressure on the grourid as an average-size person sitting in a chair, the tower

wasn't meant to stand there forever. Gustave-Alexandre Eiffel, the French engineer whose fame rested

mainly on his iron bridges, built it for the 1889 Universal Exhibition. Praised by some and denounced by

others, the tower created much argument in the 1880s. What saved it from being torn down was the

arrival of radio-as the tallest structure in Europe,it made a perfect spot to place a radio antenna

    The tower,including its antenna.is 317m high. On a clear day you can see it from 65km away. An

open-framework construction, the tower unlocked the almost unlimited possibilities of steel construction,

making the way for skyscrapers (摩天大楼). Some  people  said  it  couldn't  be built, and Eiffel actually

wanted to make it go higher. For years it remained the tallest man-made structure on earth, until

skyscrapers such as the Empire State Building came into being.

     We could fill an entire page with statistics (数据) . ( Its plans covered 5,400 sq. m of paper, and it

contains 2.5 million nails. ) But forget the numbers. Just stand under the tower, and look straight up. lt's

like a rocket shooting into the sky.

     In 2004 it became possible to ice-skate inside the Eiffel Tower, doing figure eights while taking in

views of the rooftops of Paris. Skating takes place on an observation platform 57m above ground. The

rink is a bit larger than an average tennis court, holding 80 skaters at once. Rink admission and skate

rental are free,once you pay the entry fee below.
