Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the river in front of his house.
In a      to dive into the cool river, he ran out through the back door, leaving     his shoes and shirt as he went. He dived into the water, not     that as he swam toward the middle of the river, an alligator(鳄鱼) was swimming     him. Inside the house, his mother was looking out by the window. She saw the two as they got closer and closer. In great fear, she rushed out of the house and    toward the water,     to her son as loudly as she could.
Hearing her voice, the little boy became alarmed and made a     o swim to his mother. It was too      . Just as the mother reached her son, so did the ailigator.
From the bank, the mother caught the boy by the     while the alligator snatched his leg. Then began an unbelievable tug-of-war (拔河比赛) between the two. The alligator was much      than the mother, but the mother wouldn't give up.
A farmer     to drive by. He heard the cry, raced from his truck, took aim and shot the alligator.
After weeks and weeks in hospital, the little boy was in good     again. But on his legs there were scars(伤疤)     by the animal and, on his arms, there were also scars left by his mother in her effort to hold on to the son she loved.
A newspaper reporter asked the boy      he would show his scars. The boy lifted his legs. And then, with clear      , he said to the reporter, "But look at my arms, I have great scars on my arms, too. I have them because my mother wouldn't let go. "
