He closed the door. I thought he was going to hurt me. Suddenly, a   41  voice said in my ear: “Take out the things you’ve stolen!” “I stole nothing.” I said. “Do as I tell you. If we find them, you’ll be in trouble.” “There is nothing.” I answered. “I didn’t take anything.” I said, taking everything out of my pockets and bag.

I was   45 when it rang again. I felt   46  and burst into tears. I didn’t know how to prove   47  I was innocent(清白的).
They made me go into the small room again.
