求翻译讲解一个考研英语句子。。。。感激。。。。

In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw-having extracted them from the mouths of his slaves.That's far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation.这篇文章讲的是美国总统的事情，乔治·华盛顿开国元勋，答案的翻译用了联系前后文的方法，也可以换个方法翻译的。“1784年，也就是乔治·华盛顿成为美国总统的前五年，52岁的他牙齿几乎掉光了，于是他雇了一名牙医往自己的口腔里植入了九颗牙齿，这些牙齿是从他奴隶的口中***的。这与大多数人所记得的历史书中的华盛顿砍倒樱桃树的形象截然不同，但最近，很多历史学家开始关注奴隶制在开国元勋们的生活中所扮演的角色。他们的兴趣部分源自1998年的DNA证据，它几乎肯定地证明了托马斯·杰斐逊曾与其奴隶萨利·赫敏斯育有至少一个孩子。” 考试加油！

played in the lives of the founding generation 什么意思？

翻译要联系上下文，结合语境的，这个有些乱…played做谓语，in the lives作状语，后面具体修饰，the founding generation建立的世代。有三世同堂的意味、整体为：享受着正在建立的世代生活。

英语高手进

slavery played in the lives of the founding generation. 是一定语从句，从句先行词是 the roles在从句中作动词played的宾语，所以省略了关系代词that/which。 全句意思是：但最近，许多历史学家已经开始专注于奴隶在创建人类生活时所起的作用（这一课题）。根据句子结构the roles 是主句中的宾语而slavery 是定语从句的主语，所以二者无关。
