I lived next door to Debbie and her 84-year-old mother, Nan, for about six months. One night last summer, Debbie asked me to check on her mother because she worked the overnight shift (夜班) at a nursing home.
I was glad to help. But I   1   felt a little funny about it.   2   , I’ve been blind since I was a baby and out of   3   for years. In fact, at 54, I came to wonder if I had any   4   to live.
A bit after 9:00 pm, I heard a sound—over the years my ears have grown super  5   . It was Nan. “Jim, Jim. The house is   6   ! Help!”
I went as far as I could to Debbie’s. I got to the front door,   7  for the key and unlocked the door. “Nan! Where are you?” I called.
“Here, Jim. Help!” her voice was  8   and low.
I felt my   9   inside. “Nan, where are you? Keep   10 !” “Here, Jim, here!” sounds as if she’s    11   in front of me. I reached out and touched her shoulder. We felt our way down the steps. ___12____ in the sweet, fresh summer air.
Later the fire truck arrived. Debbie came too. Nan and I heard the sound of the   13   coming down. Finally, the firefighters   14   the fire.
I heard Nan crying. She said, “I was so   15   and got turned around. I couldn’t find the door. You saved my life.”
Now Debbie’s voice quivered (发抖), “You’re a hero. You rescued my mom.”
I hardly knew what to say. Two hours earlier I was wondering whether I really mattered to anyone. And now I saved a life. Nan and Debbie were thanking me. Truth was, I wanted to thank them. Nan wasn’t the only one who had been saved that day.
