It was the end-of-year party. I had asked my mother to make us cookies. Mom’s chocolate chips were the best.

But two o’clock passed, and there was no sign of her. Most of the other mothers had come and gone, dropping off their cakes and chips. The party went on, but I wouldn’t leave the window. The three o’clock bell soon took me away from my thoughts(思绪). I took my bag and walked out for home.

The house was empty when I arrived. My heart was filled with anger(气愤). For the first time in my life, my mother had let me down. I was lying on my bed when I heard her coming. “Robbie,” she called out. “Where are you?” She was looking for me from room to room, but I kept silent.

When she came into my room, I didn’t move, “I’m so sorry,” she said. “I got busy and forgot.” She began to laugh. I couldn’t believe it. I turned over and found that she wasn’t laughing but crying. “I’m so sorry. I let my boy down.” she cried like a little girl. I had never seen my mother cry.

“It’s OK, Mom,” I said, “We didn’t need those cookies. There was plenty of food to eat. Don’t cry. It’s all right.” We held each other in a long hug(拥抱).

材料题

阅读下列材料:

材料一 “论中国政治制度,秦汉是一个大变动。唐之于汉,也是一大变动。但宋之于唐,却不能说有什么大变动,一切因循承袭。有变动的,只是迫于时代,迫于外面一切形势,改头换面,添注涂改地在变。纵说它有变动,却不能说它有建立。”

材料二 “只因宋初太祖太宗不识大体,立意把相权拿归自己,换言之,这是小兵不放心大臣,这也罢了。……但因宋初承袭五代积弊,社会读书人少,学术中衰,反对的也只晓得唐制不如此而已,并未能通览大局,来为有宋一代定制创法。”——以上均摘自钱穆《中国历代政治得失》

材料三 “倘使我们说,中国传统政治是专制的,政府由一个皇帝来独裁,这一说法,用来讲明清两代是可以的。”——黄仁宇《中国大历史》

材料四 其实中国历史上以往一切制度传统,只要已经沿袭到一百两百年的,也何尝不与当时人事相配合。又何尝是专出于一二人之私心,全可用专制黑暗四字来抹杀?——钱穆《中国历代政治得失·序》

请回答:

(1) 结合所学知识,说明材料一中秦汉和唐朝政治制度“大变动”分别指什么?

________________________________________________________________________________

(2)据材料二分析宋朝在政治体制上未能有“大变动”的原因有哪些?

________________________________________________________________________________

(3)用明清相关史实说明材料三中“政府由一个皇帝来独裁”的观点。

________________________________________________________________________________

(4) 结合明清相关史实说明,君主专制的强化不能简单地用“专制黑暗四字来抹杀”。
