In front of me, thirty pairs of eyes looked at me. I knew he had told the students that I was blind. I could almost feel the question behind their eyes: "Blind?" I felt the answer too: "If she's blind, this should be good!" I heard quiet ____ (voice) in a corner of the classroom. For a moment, I felt afraid. I knew at once that I had to be ____ (strong) than before.
"Class," I said as ____ (loud) as I could. "I may be blind. But I am not foolish. Take those naughty smiles off your faces, and stop talking, please!" Of course, I could not see their faces; I just guessed that some of them were smiling. The class were quiet. They were very surprised. I knew that I had done the right thing.
____ the days went by, the students had more surprises. I could smell when the children were eating sweets. I could easily hear combs going through hair, students ____ (pass) messages, and so on. Once I found a girl passing a message to a friend. I took the message to the teachers' room. A teacher read it to me. On one side it said, "Do you think she can see?" On the other it said, "I think so. She always knows ____ we're doing."
