"Who", I asked a senior, "is Mrs. McNamara, my 10th grade English teacher?" He just 1 and said something about my being in 2 . Soon, I understood what he meant. Mrs. McNamara had a pattern of 3 that she repeated again and again. We would have a literature reading task for 4 . The next day, when we came to class, there would be two or three topics on the blackboard 5 to the homework reading. We were 6 to write an in-class essay about one of the topics. The following day, she would 7 the corrected and graded essays and each person would be called 8 to stand in front of the class and to 9 his\her essay. The class were required to criticize (评论) that essay 10 the grade of everyone in class would be reduced. The first time that I 11 her read-write-criticize method, I had not 12 to do the homework and had written something without knowing what it meant. 13 the extreme embarrassment I suffered, standing before my classmates, 14 myself. No one laughed at me, no one would be 15 enough, or foolish enough, to do that in Mrs. McNamara's class. The embarrassment came from 16 and along with it came a strong 17 not to let it happen again. Mrs. McNamara kept all of our written work in files. It was easy to see the 18 in writing that had occurred. What was not so easy to see was the inner transformation that had taken peace, at least for me. What Mrs. McNamar 19 me to do was to see myself as others see me and, having done that, I could improve myself. And 20 . Thank you, Mrs. McNamara. | ||||
