Once two hunters went hunting in the forest. One of them suddenly fell down by accident. He showed the whites of his eyes and seemed to have ceased breathing. The other hunter soon took out his mobile phone to call the emergency center for help. The operator said calmly:"First, you should make sure that he is already dead." Then the operator heard a gunshot from the other end of the phone and next he heard the hunter asking:"What should I do next?"

　　两个猎人进森林里打猎，其中一个猎人不慎跌倒，两眼翻白，似已停止呼吸。另一个猎人赶紧拿出手机拨通紧急求助电话。接线员沉着地说：“第一步，要先确定你的朋友已经死亡。”于是，接线员在电话里听到一声枪响，然后听到那猎人接着问：“第二步怎办?”
