| Two weeks before Christmas, Mother told me we were going to my grandmother's house for the holiday. Grandma and Uncle Henry lived on a farm some 15 miles out of town. They had no electricity or running water and 1 what I considered the "good things" in life. They 2 made no plans for Christmas. When Christmas Eve arrived, Mom told me in her best "I-mean-it" voice to 3 0 all the decorations from our tree. She packed those up 4 all the trimmings(材料) for a complete turkey dinner. Christmas morning dawned perfectly with the sun shining brightly across a fresh blanket of snow. 5 I sulked(生气) silently in the backseat of the car as we made our 6 to grandma's. This was going to be the 7 Christmas ever! Grandma was 8 to see us as we walked up to her door. "What on earth are you doing here?" she stammered(结巴)." We weren't expecting 9 . It's Christmas, and I don't even have a turkey to cook for you." "I knew 10 ." Mom said as we set boxes of goodies on the kitchen table. "That's 11 12 we brought all with us." "We have a tree," Mom insisted. " Otherwise(否则), what will we do with all these decorations?" Uncle Henry quickly caught Mom's spirit. He called me to join him, and we found a perfect Christmas tree in the woods. Soon the house smelled fresh and piney as we decorated the tree, and the day take on a festive air. The turkey dinner was very good, too. I was actually beginning to enjoy this unusual Christmas day! Dessert was forgotten 13 Mom came out with the final surprise-a flaming pudding! "Merry Christmas, mother," Mom said. "Dear me!" Grandma gasped(喘息). "I haven't seen a flaming pudding since I left England before I was married." Tears of 14 filled her eyes. I could not hold the tears back, 15 . I knew then that Mom had also given me the best Christmas present ever-she had taught me what a beautiful thing it is to give. | ||||
