阅读下列材料：

材料一长期以来，很多学者将中国近代史的基本线索概括为“两个过程”，既…………同时也是中国人民反抗外来侵略和封建主义的过程。

材料二位于南京长江路292号民国时期的“总统府”，有学者说，它的社会价值和政治价值都不逊于故宫。“总统府”曾经是清代两江总督署、太平天国的天宫遗址，还象征着我国两千多年封建统治的终结。这种汇集交融的历史价值也是故宫所不具备的。

材料三史料研习、理论指导、问题研讨和社会调查是学习历史的重要方法。请运用这些方法分析近现代中国民主政治建设的发展进程。

1912年3月，孙中山颁布了参议院制定的《中华民国临时约法》。约法按照立法、行政、司法三权分立的原则构建政治体制。……它规定国务员“辅佐临时大总统，负其责任”，即实行责任内阁制。《中华民国临时约法》是中国第一部资产阶级宪法，是近代中国民主化进程的一座丰碑。

请回答：

根据材料一指出近代中国民主革命的主题是什么？，根据所学知识，列举在1840-1911年间，中国人民反封建、反侵略的重大抗争。
