bob beamon： world-record-shattering long jump
鲍勃·比蒙：1968年的惊人一跃
world records in track and field are typically broken by the slimmest of margins——a fraction of a second faster， an inch or two further. at the 1968 olympic games in mexico city， the world record for the long jump stood at 27 feet 4 3/4， and the best in the sport were vying to be the first to break the 28-foot barrier. on oct. 18， bob beamon， a 22-year-old new yorker， broke the 28-foot barrier. and the 29-foot barrier. after 19 strides down the runway， he hit the board perfectly and flew through the air like no athlete before him. when he finally landed， 29 feet 2 1/2 later， he had shattered the world record by nearly two feet. it would be 12 years before anyone jumped even 28 feet again.
众所周知，世界纪录之间的差距总在毫厘之间。不过1968年墨西哥城奥运会上的一幕算是例外。美国男子跳远选手鲍勃·比蒙以 29.25英尺（约8.91米）的成绩，将此前27.475英尺（约8.37米）的世界纪录整整提高了约两英尺，直到12年之后才有人再次跳过28英尺。
