Bad effects The Starving Sudan The Chinese Version 《饥饿的苏丹》　　?　　 这张照片是凯文.卡特赢得九四年普立兹新闻特写摄影奖的作品。那是一个苏丹女童，即将饿毙跪倒在地，而兀鹰正在女孩后方不远处，虎视眈眈，等候猎食女孩的画面。这张震撼世人的照片，引来诸多批判与质疑。当人们纷纷打听小女孩的下落，遗憾的是，卡特也不知道。他以新闻专业者的角色，按下快门，然后，赶走兀鹰，看着小女孩离去。?　 　在他获颁这一生最高的荣誉两个月之后，卡特自杀身亡。道德良心上的遣责，可能是卡特无奈结束生命的原因之一吧？　　?　　 在我们周围，正有无数这样的图像在形成、在发生，你我是否也仅止于按下人生镜头的快门，然后，漠然地擦肩而过？ Do you know what are they doing?
