That morning, I stepped into the classroom, ready to share my knowledge and experience with seventy-five students who would be my English Literature class. Having taught in  1 for seventeen years, I had no  2  about my ability to hold their attention and to  3  on them my admiration for the literature of my mother tongue.
I was shocked when the monitor shouted, "  4  !" The entire class rose as I entered the room, and I was somewhat  5  about how to get them to sit down again, but once that awkwardness was over, I quickly  6  my calmness and began what I thought was a fact-packed lecture, sure to gain their respect—perhaps  7  their admiration. I went back to my office with the rosy glow which came from a sense of achievement.
My students  8  diaries. However, as I read them, the rosy glow was gradually  9  by a strong sense of sadness. The first diary said, "Our literature teacher didn’t teach us anything today.  10  her next lecture will be better." Greatly surprised, I read diary after diary, each expressing a  11  theme. "Didn’t I teach them anything? I described the entire philosophical framework of Western thought and laid the historical  12  for all the works we’ll study in class," I complained." How _13  they say I didn’t teach them anything?"
It was a long term, and it  14  became clear that my ideas about education were not the same as_15 of my students. I thought a teacher’s job was to raise   16  questions and provide enough background so that students could  17 their own conclusions. My students thought a teacher’s job was to provide _18_ information as directly and clearly as possible. What a difference!
_19 , I also learned a lot, and my experience with my Chinese students has made me a  20  American teacher, knowing how to teach in a different culture.
