Wings of Angel
I used to hate myself because I wasn't "normal". Everyone else could play on the monkey bars and ride on a bicycle, but not 36 . I had a severe spinal cord disorder(脊髓病) and I knew I would always be much 37 than others. I hated going to school and I hated others 38 at me. I hated seeing others smiling broadly and standing 39 and tall. And most of all, I hated looking in the 40 and seeing an ugly hunchback(驼背).
My friends found me 41 because I didn't let other get close to me. I thought I was going to go on like this for the rest of my life 42 Angela appeared.
That afternoon, I was sitting by myself in a corner of the school—a spot where no one would 43 me. That's when I first heard your voice. "Hi. Can I sit down?"
I raised my head and there she was, with an irresistible smile on her round face. "What are you looking at?" you asked. "Ants." "What are they doing?" "No 44 ." "I bet they're playing games and make friends. Don't you think so?" That was how our 45 started and it didn't stop. We talked about everything under the sun—the ants, the clouds, my little niche(处境)—until it was sunset. Then suddenly, you saw my 46 . She just stared. My heart 47 . What I feared most had happened and I knew for sure she would 48 me now. She stood up, pointed at my back and said, "I know 49 your back is hunched." I closed my eyes like a criminal waiting to be 50 . I begged in my heart for her to 51 , but she just kept on going. "I know what you've got there. Do you?" "No," I answered 52 . She bent and whispered in my ears. "Your back is bunched because you've got a pair of wings from the angels."I was 53 . I looked into her eyes and her 54 touched my heart. From that day on, I started to learn to 55 myself because I have the wings of an angel and a kind_hearted friend.
