马克思认为：“英国革命和美国革命对现代民主政治的创新具有重大意义。”这里的“创新”主要是指（）
A.确立了资本主义国家现代化的政体典范
B.促进了资本主义经济的快速发展
C.第一次完成了民族民主革命的双重任务
D.建立起中央集权的民主共和国
参考答案：A
解析：
本题考察英美法三国资产阶级代议制确立过程中的重大历史事件和现象、英美法德四国宪法的内容及代议制的特点等是高考命题的高频点 。B属于经济方面的影响，与题干“对现代民主政治的创新具有重大意义”不符；CD适合于美国革命即北美独立战争，而不适用于英国革命，英国革命不是民族革命，而且最终确立的是君主立宪制。
考点：欧美代议制的确立与发展·美国共和制的确立·美国1787年宪法；欧美代议制的确立与发展·英国君主立宪制的确立·英国君主立宪制的确立影响
