It was an early morning in summer. In the streets, sleepy-eyed people were moving quickly, heading towards their jobs .This was the beginning of another ordinary day in New York City. But this day was to be different.
Waiting above the crowded streets, on top of a building 110 stories high, was Philippe Pettit. This daring Frenchman was about to walk a tightrope(绷索)between the two towers of the World Trade Center.
Philippe took his first step with great care. The wire held. Now he was sure he could do it. With only a balancing polar, Philippe walked his way across, a distance of 131 feet.
Soon the rush-hour crowds began to notice. What a wonder!There,1350 feet above the street, a tiny figure was walking on air.
Philippe made seven trips, back and forth(来回).He wasn't satisfied with just walking. At times, he would turn, sit down, and even go on his knees. Once, he had the astonishing courage to lie down on the thin thread. And thousands of terrified watchers stared with their hearts beating fast.
After the forty-five-minute show, Philippe was taken to the police station. He was asked why he did it. Philippe shrugged(耸肩)and said, "When I see two tall buildings, I walk."[NMET94]
