My dad was driving to the city center to shop and I was going along for the ride. At least that was what I had told him— 1 I had an important question to ask—that had been on my mind for a couple of weeks and this was the first time I had been able to 2 with him alone. “Dad…”I started. And 3 . “Yes?” he said. “The kids say there is no Father Christmas. They say I’m 4 to believe in Father Christmas anymore…it’s only for little kids. But I believe what you told me. Father Christmas is __5 . He is, isn’t he, Dad?” “The real life and spirit of this magical elf (精灵) lives forever in your heart, my heart, Mom’s heart and in the hearts and minds of 6 people who believe in the joy that giving to others brings. The real 7 of Father Christmas becomes what you can give rather what you get. Once you understand this and it becomes 8 of you, Father Christmas becomes even more exciting and more magical because you come to 9 the magic comes from you when Father Christmas lives in your heart. Do you understand what I am 10 to tell you?” My heart was filled with pride and I’m sure my eyes were shining with 11 .” Of course, Dad. I want him to be in my heart, just like he’s in yours. I love you, Daddy. You’re the best Father Christmas who has 12 been in the whole world.” When it comes time in my life to 13 the reality of Father Christmas to my children, I hope that I will be as eloquent (有口才) and 14 as my dad was the day I learned that the spirit of Father Christmas doesn’t wear a red 15 . And I hope they will accept me as I did that day. I’m sure they will.
