Watching some children trying to catch butterflies one hot August afternoon, I        of one thing in my own childhood．When I was a boy of 12 in South Carolina,          happened to me that I gave up putting any wild animal in a cage forever in my life. We lived on the edge of a wood, and every evening ，the mocking birds （知更鸟）would come and rest in the trees and sing. There isn’t a musical instrument made by man that can make a          beautiful sound than the song of the mockingbird.
I decided that I would catch a young bird and keep it in a cage and in that way would have my own     musician. I finally succeeded in catching one and put it in a cage. At first, in its fight at being caught, the bird fluttered(拍翅膀) about the cage, but at last it kept calm in its new home. I felt very pleased with          and looked forward to the beautiful           from my little musician.
I had left the cage out on our back yard, and on the second day my new          mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this.        the mother knew better than I how to feed her baby.
The following morning when I went to see how the bird was doing, I discovered it on the floor of the cage, dead.
I was quite          ! What had happened! I had taken excellent care of my little bird, or so I thought.
Arthur Wayne, the famous ornithologist(鸟类学家), happened to be visiting my father at the time, hearing me crying over the death of my bird, and he gave me an explanation of something that had happened. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison（有毒的） berries. She thinks it better for her young to die than to live in cages.”
Never since then have I caught any living creature (生物) and put it in a cage. All living creatures have a right(权力)        .
