The simplest way to say it is this: I believe in my mother. My belief began when I was just a kid, who    36   becoming a doctor.
My mother was a domestic（佣人）. Through her work, she observed that   37   people spent a lot more time reading than they    38   watching television. She announces that my brother and I    39  watch two to three pre-selected programs during the week. With our   40  time, we had to read two books each from the Detroit Public Library and   41   written book reports to her. She would mark them up with check marks and highlights. Years later we realized her marks were a    42  . My mother was illiterate（文盲）.
When I entered high school, I was a    43   student, but not for long. I began to like fancy clothes. I wanted to    44   other guys. I went from an A-student to a B-student to a C-student. One night my mother came home from her various jobs and I    45   about not having enough Italian knit shirts. She said, “Okay, I’ll give you all the money I    46   this week scrubbing floors and cleaning bathrooms, and you can buy the family food and pay the bills. With the money    47  , you can have all the Italian knit shirts you want.” I was very    48   with that arrangement but once I got through allocating（分配）money, there was   49   left. I realized my mother was a financial genius（金融天才）to be able to keep the roof over our heads and any kind of food on the table, let alone buy    50  . I really realized my desire wasn’t going to get me    51  . Success requires intellectual preparation. I went back to my    52   and became an A-student again and eventually I    53   my dream and I became a doctor.
My story is really my mother’s story—a woman with    54   formal education who used her position as a parent to change the lives of her children. There is no job    55   than parenting. This I believe.
