47. 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Many years ago, when I was a little child, my elder brother whispered to me that there wasn’t Santa Claus in the world before Christmas. Hearing this, I immediately rushed to my grandmother’s house because she was my most trustworthy person and she would tell me anything she knew to me. It so happened that she was at home. After I told her what my elder brother had told me, she shouted “No Santa Claus Ridiculous (荒谬)! Don’t believe it” What upset most was that the rumor had been going around for years, and it mad me mad, plain mad.
“Now, follow me.”
