My father was in the navy, which meant that my mother was married to both my father and the sea. As was often the       , we had to pack our belongings into boxes and    those we had grown to love. We would arrive at our new home and find ourselves once again standing at the pier (码头)      good-bye to my father as his ship pulled him away from us. My mother would turn my brother and me around before the ship was out of     , wipe our tears, and take us back home to start the process of    in the new environment again.
Throughout the years of changing     , schools and friends, there remained one constant in my childhood — my mother. For both my    and me, she was the cook, maid and teacher. She played these roles while    some type of part-time job. Leaving a       career is just one of the sacrifices which my mother made for my family as we moved around the world with our father every three years or so.    she had to deal with only a small budget, my mother,     , managed to make each house the very home that is safe and     .
This probably sounds like a depressing way to live,      with two small children:  “single”
parenthood, short-term friendships, and the inability to    her career or establish a home. But it was not for my mother. She turned this    into adventure for us all! Each relocation (变换位置) was a chance to    another part of the world. My mother greeted each new culture, climate and neighborhood. Each new house was a    to rearrange furniture, make curtains and    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    attitude. She always had strength in the face of struggle and change. My mother was so    all those years during my childhood — she was my island in a sea of change. She is my hero.
