两个人结伴穿越沙漠。水喝完了,其中一个人中暑生病,无法行动,另一个健康又饥渴的人对他说:“好吧,你在这里等着,我去寻找水源。”他把手枪塞到同伴的手里,说:“枪里有五颗子弹,记住,三个小时后,每小时对空鸣枪一声,枪声指引我,我会找到正确的方向,然后与你会合。” Two people go through the desert together. When the water was over, one of them got sick and could not move because of heat stroke. Another healthy and hungry man said to him: “Well, you are here waiting for me to look for water.” “He stuck his pistol to his companion And said: ”There are five bullets in the gun. Remember, after three hours, I shot the gun every hour, and gunshots guided me. I would find the right direction and then meet you.“ ”
