My father was in the navy, which meant that my mother was married to both my father and the sea．As was often the case, we had to pack our belongings into boxes and 31 those we had grown to love．We would arrive at our new home and find ourselves once again  32  at the pier （码头） waving good-bye to my father as his  33  pulled him away from us．My mother would turn my brother and I around before the ship was out of  34 , wipe our tears, and take us back home to start the process of  35  in the new environment again．
Throughout the years of changing  36 , schools and friends, there remained one constant in my childhood — my mother．For both my  37  and I, she was the cook, maid and teacher．She played these roles while  38  some type of part-time job．Leaving a promising career is just one of the  39  which my mother made for my family as we moved around the world with our father every three years or so． 40  she had to deal with only a small budget, my mother,  41 , managed to make each house to be the very home that is safe and  42 ．
This probably sounds like a depressing way to live,  43  with two small children: “single” parenthood, short-term friendships, and the inability （无能） to  44  a career or establish a home．But it was not for my mother．She turned this  45  into adventure for us all! Each relocation （变换位置） was a chance to  46  another part of the world．My mother greeted each new culture, climate and neighborhood．Each new house was a  47  to rearrange furniture, make curtains and  48  pictures．Every part-time job was an opportunity to learn something new and work with interesting people．
No matter how difficult the life was, she was always having a  49  attitude．She always had strength in the face of struggle and change．My mother was so  50  all those years during my childhood — she was my island in a sea of change．She is my hero．
