结构分析
你需要知道（感兴趣的同学可以了解一下，但不作为掌握重点~）
1.主语补足语是对主语的补充，使得句子更加完整。它用在系动词后，是句子的一个基本成分。它和限制性定语、解释性定语不同，后面两者为从属成分，去掉后不影响句子结构。
2.被动语态的主语补足语与主动语态的宾语补足语是密切相关的。例如：
(1) I saw him playing basketball yesterday.
(2) He was seen playing basketball yesterday.
句（1）中的含义不是我看见他，而是我看见他正在打篮球。playing basketball是宾语him的补足语。所以叫宾语补足语。
句（2）中的含义不是他被看见，而是他正在打篮球被别人看见。这里的playing basketball是主语he的补足语，故称作主语补足语。
主语和主语补足语一起称作复合主语。含有主语补足语的句子一般是被动语态，谓语动词是可以接复合宾语（宾语+宾语补足语）的及物动词。句首的主语就是主语补足语的逻辑主语。
翻译
在目睹了独立战争中黑人士兵的勇敢后，华盛顿开始相信人人生而平等，从而克服亲属的强烈反对，在遗嘱中给予了他的奴隶自由。
