[单项选择]When my first wartime Christmas came, I was in basic training in New Jersey and not sure if I could make it home for the holidays. Only on the afternoon of December 23 was the list of men who would have three-day passes posted. I was one of the lucky soldiers. It was Christmas Eve when I arrived home, and a light snow had fallen. Mother opened the front door. I could see beyond her, into the corner of the living room where the tree had always stood. There were lights, all colors, and ornaments (装饰物) shining against the green of a pine. "Where did it come from" I asked.
"I asked the Gates boy to cut it," my mother said. "I wouldn’t have had one just for myself, but when called—oh, such a rush! He just brought it in this afternoon..." The pine reached to the proper height, almost to the ceiling, and the Tree Top Krystal Star was in its place. A few green branches reached about a little awkwardly (不够美观地) at the side, I thought, and there was a bit of bare trunk showing in the middle.
A. it was December 23

C. he found a Christmas tree in the living room
D. the Gates boy was cutting a Christmas tree for his mother
