There was a 2 near our house. In winter it was the greatest 3 place in the world. One 4 all I wanted to do was go skating. I had been waiting for weeks 5 the water was frozen solid. Mom had one rule: "Never ice-skate alone." But I couldn't 6 any longer that afternoon. So I 7 my skates under my coat and ran to the pond. Several people were skating near the shore, and some kids were playing hockey. I was not really 8 . The hockey game had attracted 9 audience, so I skated in the other direction until their cheering 10 . But another noise came soon. The ice was cracking beneath me. Freezing water 11 my body, and I sank like a rock. My feet 12 the bottom. Just when I thought I wouldn't last another 13 , I felt a tap on my shoulder. "Don't worry," someone said. I swung my 14 around. I couldn't see anybody. But I heard the voice again,"Push your feet into the bottom and you'll shoot straight up to the surface." I did as I was told and 15 . I crawled to the shore and lay down, 16 .The next thing I knew was people were 17 around me, covering me with coats. When I awoke, I was home in my own bed. Mom sat next to me, 18 my hand. "I saw nobody there. It must be an angel that came to my 19 ." I said. Mom smiled, "I just thank God you're safe." For a long time I thought I would 20 a more realistic explanation if I just thought hard, but I never did. | |||
