　　America and Americans were prosperous beyond the dreams of the Europeans and Asians whose economies the war had destroyed.whose 短语在定语从句中90%的情况是做主语，做宾语的情况很少见，一般要把宾语转换成被动语态，如：The White House also released returns for Vice President JoeBiden and his wife, Jill, whose income is far surpassed by the Obamas。白宫还公布了副总统拜登(JoeBiden)及夫人吉尔(Jill)的退税情况,他们的收入远远不及奥巴马夫妇。这样来看句子whose economies that had been destroyed in the war容易理解一些。在原句中，the Europeans and Asians后边跟的是定语从句，whose economy引导定语从句，从句主语是the war, 谓语是had destroyed ,whose economy做宾语。变回去是The war had destroyed the Europeans and Asians's economy.相似的句子比如句一：We like Kitty. The policeman has killed kitty's father.-----We like Kitty whose father the policeman has killed. 句二：Biden also emphasized his working-class roots, trying to appeal to a group of voters whose support Obama has struggled to attract. 拜登同时也强调他自己出身工薪阶级,从而试图吸引奥巴马已在努力吸引的选民。
