分析英语长句结构成分

（1）About seventeen months before his death 是时间状语；
（2）at the opening of a memorial to many men who lost their lives fighting for the freedom of the Negroes 是地点状语，在这个状语里有一个定语从句，先行词是many men, 在从句who lost their lives fighting for the freedom of the Negroes 作主语；
（3）Abraham Lincoln told his people that.....是这个句子的主句，其中主语是Abraham Lincoln，谓语是told，（间接）宾语是his people，（直接）宾语是后面三个that的宾语从句。
（4）分析一下3个宾语从句的主谓宾：
第一个：that the living must finish the work of those dead, 主语是the living，谓语是 must finish，宾语是 the work of those dead。
第二个：that they must fight for freedom for all --Negroesand Whites, 主语是they，谓语是 must fight for，宾语是freedom，后面Negroesand Whites是all的同位语。
第三个：tAmerica must strengthen the government of the people, by the people and for the people, 主语是America，谓语是must strengthen，宾语是 the government。
