完形填空（共15小题；每小题1分, 满分15分） 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 37 . I had a severe spinal cord disorder (脊髓病) and I knew I would always be much 38 than others. I hated going to school and I hated people 39 at me. I hated seeing others smiling broadly and standing straight and tall. And most of all, I hated looking in the 40 and seeing an ugly hunchback (驼背). My friends found me distant because I didn’t let others get 41 to me. I thought I was going to go on like this for the rest of my life 42 Angela appeared.

She bent and 49 my ears. “Your back is hunched because you’ve got a pair of wings from the angels.” I was 50 .I looked into her eyes and her kindness touched my heart. From that day on, I started to learn to 51 myself because I have the wings of an angel and a kind-hearted friend.
