<TEXT>
当年朝鲜战争中的韩国难民生还者拒绝接受美国总统克林顿星期四的声明，克林顿对当年美国军人打死韩国平民表示遗憾。
代表这些生还者的发言人表示：“克林顿的声明只是文过饰非。”
并誓言要将此案送交国际法庭。
克林顿总统在声明中对１９５０年７月老根米村附近发生的事件深表遗憾。
说那次的事件留下战争悲剧和战争创伤的痛苦记忆。
后来国防部长科恩表示：“美国将为当年伤亡的平民树立一座纪念碑，并且设立一个奖学金纪念战争死难者。”
死难者家属要求美国明确道歉，并且给予直接赔偿。

ＥＭＰＴＹ
父母外出打工后，孩子留在了农村的家中。
他们被称为留守儿童。
外出打工的父母也是很无奈的，实际上他做出这种选择是非常无奈的。
中国一点二亿农民常年在外地务工，产生了近两千万留守儿童。
我想跟他们说，我好想他们。
他们日复一日年复一年的在孤独中期盼着被爱，在残缺中守望着亲情。
对孩子的情感交流，我觉得特别重要。
在这个条件容许的时候，多回家看看孩子。
