      The yearly Marathon in my town usually happened during a heat wave. My job was to follow behind the
runners in an ambulance (救护车)   1   any of them needed medical attention.
       "We're supposed to stay behind the   2   runner, so take it slowly," I said to the driver, Doug, as the race
started.
       The front-runners started to   3   and then my eyes were drawn to the woman in blue silk running shorts
and a loose white T-shirt.
       We knew we were already watching our "last runner." Her   4   were so crippled (残疾的) that it seemed
almost impossible for her to be able to walk, let alone run a marathon.
       Doug and I watched in silence as she slowly moved forward.   5  , she was the only runner left in sight.
Tears streamed down my face when I watched with respect   6   she pushed forward with great determination
through the last miles.
       When the finish line came into sight, rubbish lay everywhere and the   7   crowds had long gone home.
Yet, standing straight and ever so proud   8   a lone man. He was   9   one end of a ribbon (缎带) of crepe
paper (皱纹纸)  10  to a post. She slowly crossed through, leaving both ends of the paper fluttering behind
her.
       I do not know this woman's name, but that day she became part of my  11  - a part I often depend on.
For her, it wasn't about  12  the other runners or winning a prize, but about  13  what she had set out to do,
no matter  14 . When I think things are too difficult or I get those "I-just-can't-do-it," I think of the last runner.
Then I realize how  15  the task before me really is.
