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 people   38  at me. I hated seeing others smiling broadly and standing straight and tall. And most of all, I hated looking in the   39  and seeing an ugly hunchback (驼背).
My friends found me   40  because I didn’t let others get close to me. I thought I was going to go on like this for the rest of my life   41  Angela appeared.

“Hi. Can I sit down?”
I raised my head and there she was, with an irresistible smile on her round face.

She stood up, pointed at my back and said, “I know   46  your back is hunched.”
I closed my eyes like a criminal waiting to be sentenced. I begged in my heart for her to   47 , but she just kept on going. “I know what you’ve got in there. Do you?”
“No,” I answered   48 .
She bent and whispered in my ears.
“Your back is hunched because you’ve got a pair of wings from the angels.”  
I was   49 . I looked into her eyes and her kindness touched my heart. From that day on, I started to learn to   50  myself because I have the wings of an angel and a kind-hearted friend.
