1.（19分）阅读下面的文字,完成以下各题。

材料一：

在世界几大古代文明中，中华文明源远流长、从未中断，至今仍充满蓬勃生机与旺盛生命力，这在人类历史上是了不起的奇迹。本固根深、一脉相承的历史文化是铸就这一奇迹的重要基础。

先秦时期是中华文化的创生期，奠定了此后几千年中华文化发展的基础。考古发现证实，早期中华文明的形成经历了从“满天星斗”到“月明星稀”再到“多元一体”的过程。在这个过程中，不同地域、不同人群的文化交流交融，中华民族最早的大家庭逐渐成形，国家由此诞生，“大同”社会理想和“天下为公，选贤与能，讲信修睦”的价值追求逐渐深入人心。在早期国家形成过程中，我们的先人积累了初步的国家治理经验，包括经济、政治、军事、法律、文化等各个方面，最终以典章、思想的形式进行总结和传承。流传至今的夏商西周国家治理经验、春秋战国诸子百家思想，是先秦时期历史文化的集中反映。

秦汉至宋元时期是中华文化的发展期，中华传统文化在这个时期走向成熟并迈向新的高峰。中央集权制度的形成、郡县制度的推广、官僚制度的健全，推动中国传统社会形成国家治理的基本形态，为中国传统社会的长期延续和发展提供了坚实的制度和文化支撑，贯穿其中的价值主线是对“大一统”的坚定追求。与此同时，民为邦本的民本思想、以文化人的文治主张、协和万邦的天下观等，也在实践中得到丰富和完善。在追求“大一统”的历史中，民族精神世代相传，民族英雄史不绝书。

明清以降是中华文化的转型期，形成了具有深远影响的丰厚遗产。这个时期的中国，传统文化积淀愈益深厚，“大一统”趋势愈益强化，新生社会因素愈益彰显。其中，最值得重视的是全新历史变局的出现和中国人民的抉择。1840年鸦片战争爆发后，中国陷入半殖民地半封建社会的苦难深渊。面对新的时代变革，中华民族显示出强大的生命力和创新力，一代又一代中国人不甘沉沦、前赴后继、浴血奋斗，最终找到马克思主义这一科学真理。在中国共产党的领导下，中华民族几千年来积淀、积聚的爱国情怀、创造活力被激发出来并发扬光大，古老的中华文化从此获得历史性新生，为中华民族伟大复兴奠定了坚实基础。
