    In it's 40’s, its’ long and flexible talons (爪) can no longer grab prey (掠食) which serve as food, its' long and sharp beak (鸟嘴, 喙) becomes bent. Its’ old-aged and heavy wings, due to their thick feathers, become stuck to its’ chest and make it ___2___ to fly. Then Eagle is left with only two options: die or go through a painful process of change which lasts 150 days for survival.

    The process requires that Eagle fly to a mountain top and sit on its’ nest. There the Eagle knocks its' beak ___3___ a rock until it plucks (拔去) it out. After plucking it out, Eagle will wait for a new beak to grow back. When its’ new talons grow back, the eagle starts plucking its' old-aged feathers and after five months, eagle can take its' flight of rebirth and lives for thirty ___4___ years.

    Many times, in order to survive, we have to start a change process. We sometimes need to ___5___ old memories, habits and other past traditions. Only freed from past burdens, can we take advantage of the present.
