Two days before Thanksgiving, I was trying to open my mouth wide enough for a mirror and a roll of steel wire. Metal braces (牙齿矫正器)had been on my   31   for weeks, but this was the day for the wire to be adjusted. Only those who have had braces will understand the terrible   32   of being “wired”. For the next 24 hours, it felt like every tooth was being   33   slowly by a giant clawhammer (拔钉锤).  34   drinking water caused pain.
By Thanksgiving Day, I had got used to it.   35   I didn’t use my teeth, the pain was bearable. But this was a day when teeth had to   36   longer than usual. We were   37   at my grandparents’ house with relatives. The house was filled with so many pleasant   38   that we could hardly resist the food. When grandma said, “Dinner is ready!” all the kids   39   to be first in line. I was so excited that I    40   the braces in my mouth and   41   my way up to the head of the line.
I piled my plate high with my favorite corn-on-the-cob(玉米棒子)and   42   my mouth to enjoy it. The pain was   43  . I felt I would never be able to eat again. I put my plate away and ran outside in   44  .
Grandma then took my plate to the   45  . She cut all the corn off that cob and rescued me from my   46  . She handed me my plate piled high with corn. “Thanks,” I said   47  . Then I looked up and   48   a strange light in her eye, a light that is still   49   to me after more than fifty years. That was the Thanksgiving when I discovered something more   50   than good food.
