There were several years that have left an extremely bitter taste in my mouth .The first few months after my mother’s remarriage were sweet: baseball games, family trips to the mall, dinners and movies together. Then things      . Baseball became too expensive, and trips to the mall were      by days Emily and I spent lonely in our rooms under our stepfather’s      . Moreover, screaming matches between him and our mother always      dinner. We spent five years living in a family that had      a war field. Emily and I almost grew used to this situation. Then one evening, after another argument had      , we were left homeless . And later a friend of my mother let us stay with her. Instead of focusing on our economic problem, my mother      pushed me to struggle for success. She wanted me to lead a      life. She worked long hours every night to pay her bills.      , she would find time to read and play with Emily and me. Mom taught me the      of perseverance (坚持不懈) and education.

And now, writing this essay with my favorite candy close at hand, I realize my family and I are at the best points of our lives.
