People donate their blood to strangers, travel on humanitarian missions to places such as Haiti and the Sudan, and risk their lives to fight injustice elsewhere. And New Yorkers have grown accustomed to reading about subway heroes – brave souls who leap onto the tracks to rescue fallen commuters and then often slip away, uncomfortable with attention or credit.
人们捐血给素不相识的人，奔赴海地和苏丹等地实施人道主义救援，舍身忘死地与其他国家的不公正行为作斗争。而纽约人也越来越对关于地铁英雄的报道司空见惯——那些勇敢的人奋不顾身跳下铁轨营救失足的旅客，却往往在他人安全脱险之后悄悄溜走，不希望引起注意，也不渴望得到表扬。
