Everyone was shocked（震惊） by the cry. They took me into a classroom and were about to take off my1. “Which foot is it?” One asked “let us have a look.”
Suddenly, I remembered the holes in2socks. My family was very poor during those years. I wore welfare （福利）socks, which cost only a little, but those3welfare socks didn't last long. They soon had 4at the bottom.
