29、thing to us (nothing could break the silence of reading periods), she would place two fingers lightly on our throats and hold them there for seconds.

I kept my eyes on the material I was reading and waited for her to place her fi

31、ngers lightly on my throat. One day, out of curiosity, I raised my head from my book—though not high—so that I could see Ms. Hunter, a white woman from Canada, moving up and down the rows, stopping at the desks of my classmates. I wanted to see how they reacted when she touched their throats. She w

I sat up straighter in my chair, thinking that my way of sitting might be the problem. I was confused. Several days later, I watched again, this time rais

33、ing my head a little higher. Nothing changed. Ms. Hunter touched the same students. Always, she touched me. She touched me with her hands. She also touched me with her belief in my ability to achieve. She motivated me by demanding the best from me and by letting teachers I would meet in junior high

34、 school know that I should be challenged, that I would be serious about my work. I am convinced that she touched me because she could “see” me in the future. That was true of all of us at Fair Oaks who sat still and silent as Ms. Hunter placed her fingers lightly on our throats. We left Fair Oaks as

35、 “best students”， entered John Marshall Junior High School, finished at the top of our high school class, and went on to earn graduate degrees in various subjects.
