8 阅读理解。 A baby camel asked his mother, "Why do we have such large hooves (蹄) on our feet?" She turned him and began her explanation. "The big hooves are to keep us from sinking into the sand." "Oh! So why do we have long eyelashes (睫毛)?" "It"s to protect our eyes from the sand." "Why the big humps (驼峰)?" "That is to store fat and have enough energy to go long distances in the hot desert!" "I see!" The baby camel stretched his neck and looked up at his mother,"Then what are we doing in this cage in the middle of a zoo?" Like the baby camel, I had asked the same kind of questions.

Those bars were self-imposed (自我强加的). Finally, eagerness to leave it inspired me to open my ears to hear a reassuring whisper-I was created for much more. I broke down those bars and stepped out into the desert of life. I walking difficultly through the heat with determination. And the hooves of confidence kept me from sinking into the sand of danger. Each time I reached another point in my journey, my eyes saw a whole new world with opportunities to make a difference. Best of all, I was pleased the I was indeed created for much more!
