One of my fondest Christmas memories was also one of our family’s bleakest（最令人沮丧的）.We were just little kids , and on Christmas Day mom   36 us all around her to tell us ,  37 ,that there would be no presents because all we really wanted was to  38 for our daddy.He was very sick . I don’t remember anything else except four little girls surrounding my mother, crying   39 a miracle（奇迹）

At that very moment ,someone   40 loudly on the door.  41 Behind him was a merry group of soldiers from the Army base where my father   42 as a minister . News had  43  that we were in trouble ,and his colleagues knew we needed some  44  .

With all the excitement ,even my dad  45  in a blanket to keep warm , came down and sat in front of a roaring fire in our room to watch his children be  46 by good Samaritants（乐善好施的人）. The presents were unwrapped , and we girls  47  packages and found a doll each and four board games.

What is  48  to me is that I don’t even remember what sickness my father was suffering from.I 49  remember an evening of laughter and  50  There were no expensive toys but    51 moments of friendship and fun given by young men who knew that a family was having a(n)  52 time . They gave their time and their  53 to little children who needed to laugh.

The most important thing in life aren’t things . And what about the true  54  of holidays ? I hope we all are able to remember a thing about the holidays that stirs(搅动)our heart , that isn’t really a thing at all, but the smile on a child’s face because we take a moment to hug or   55 a tear.
