It was a lovely spring afternoon. My classmates and I were playing _________on the playground when I let out a cry, “Ow! Ow! Something in my shoe is biting me.”

Everyone was shocked by the cry. They took me into a classroom and were about to take off my shoe. “Which foot is it?” one asked. “Let _________ have a look.

Suddenly, I remembered the holes in my socks. My family was _________ poor during those years that my parents couldn’t buy me good socks. Instead, I wore welfare（福利） socks, _________ cost only a little, but those cheap socks didn’t last long. They soon had holes at the bottom.

I refused _________ off my shoes. I couldn’t stand others seeing the holes in my socks. I tried to hold back my tears. Yet, each time the thing in my shoes bit me, tears raced down my face.

My teacher, Miss Diane, hurried into _________ classroom. “What’s wrong?” She asked.

“Something is biting her right foot,_________ she doesn’t allow anyone to take off her shoe,” one of my classmates answered.

Miss Diane lived next door to me. She knew everything _________ my family. She put_________ hands on my shaking shoulders and looked into my painful and hopeless eyes.

“Oh, yes, it __________ be a sock-eating ant,” she said, as if she had already seen the thing inside the shoe. “I remember __________ I had a bite from one of those ants. By the time I got off my shoe off, it had eaten almost the whole bottom off my sock.” My classmates nodded while they were listening to the teacher carefully, although they all looked a little __________.

Miss Diane took off my right shoe and sock and __________ them over the dustbin. Two red ants fell into it.

“Just what I thought. The ants have eaten part of her sock.” When she stroke an alcohol(酒精) cotton ball on the bites, she added, “You are __________ brave girl to take so many bites.”
