【历史—选修2：20世纪的战争与和平】

材料一：1940年6月，当法国政府战败投降之际，戴高乐将军发起了“自由法国”运动，向法国人民发出了坚持抵抗的号召，他通过英国电台多次向法国人民发表演讲，指出法国输掉一场战役，但没有输掉这场战争；法国并不是孤立的，在它的后面还有一个广大的法兰西帝国（海外殖民地）；法国可以和英国结成同盟，它还可以利用美国取之不尽的资源。

材料二：第二次世界大战给英国经济造成巨大破坏，人民生活水平急剧下降。1942年，英国工党提出了不分阶级，不分贫富，人人都有权享有社会福利的主张，得到越来越多的民众的支持。1945年，工党在大选中获胜。1948年，工党政府首相艾德礼宣布实行《家庭津贴法》《国民保险法》《国民医疗保健法》《国民救济法》等一系列社会保障法，为英国建立福利国家奠定了基础。
