***谈到大国崛起时强调:任何一个民族、任何一个国家都需要学习别的民族、别的国家的优秀文明成果。中国要永远做一个学***国，不论发展到什么水平都虚心向世界各国人民学习，以更加开放包容的姿态，加强同世界各国的互容、互鉴、互通，不断把对外开放提高到新的水平。”回顾美俄强国之路，回答以下问题：

材料一：美国纽约自由岛上有座自由女神像，女神双唇紧闭，头戴光芒四射的冠冕，身着罗马古代长袍，右手高擎长达12米的火炬，左手捧着用铜板刻成的《独立宣言》，上面用罗马数字镌刻着脚下是打碎的手铐、脚镣和锁链。

材料二：美国在19世纪60年代成为了单一的、联合的、强大的国家，这奠定了美国在20世纪成为世界第一强国的基础。如果美国在当时分裂成了两个或者更多的国家，或者北方没有赢得胜利，这是根本不可能实现的。所以，这场战争对美国产生了深远的影响。

材料三：我们美国正在打一场伟大而成功的战争。这不仅是一种反对匮乏、贫穷与经济不景气的战争，而且是一种争取民主政治和生存的战争。我们正为挽救一种伟大而珍贵的政府形式而战；既是为我们自己，也是为全世界。

——富兰克林·罗斯福
