| I keep a two-dollar bill in my wallet (钱包). My mother gave it to me when I was six years old. The bill goes with me wherever I go because I believe luck would 1 me everywhere. Whenever I felt there was a trouble, I would 2 for my two-dollar bill and set it on the table, I would watch it for several hours and could always come up with 3 . When I began to look for my first job, I was thirty years old and very 4 . The thought of being interviewed (面试) for a job was scary (恐怖的) but I had to work. Mrs. Martin, the office manager, asked me some questions and the interview was over. As I got 5 her office, I said, "Mrs. Martin, I know that I am not the best applicant (申请者), but please give me a chance. I learn quickly and can be a very 6 member of your team." That evening I received a phone call from Mrs. Martin. "Gina," she said. "You were not the best applicant, but you have so much confidence (信心) in yourself that we have 7 to give you a chance." "Thank you so much, Mrs. Martin!" I said. I was so excited that I forgot to say 8 to Mrs. Martin. I took out my two-dollar bill. "Thanks, Mom. I am going to 9 it," I sad out loud so my mother could hear me. At that moment, I remember the time she pulled all of us into the living room and said, "You are all clever in my 10 , but if you fail once, don't give up. You will be successful." I still think of Mom every day and keep my two-dollar bill in my wallet. At a family reunion (团聚) years later, I found that my brothers and sisters 11 had two-dollar bills in their wallets. We laughed and talked about how 12 this gift from Mom had been to each of us. |
