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.

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.
