1. Ever since the Civil War, the South has struggled to find ways to deal with its troubled past. 在内战以来，美国南部就一直在设法处理过去遗留下来的麻烦事。
troubled：worried; full of problems and conflicts不安的；混乱的
Little Tom was deeply troubled when he broke the cup.
打破了杯子，小汤姆深感忧虑。
The People in that country live in troubled times.
那个国家的人民生活在动乱不安的时代里。
2. The history of the South is one of suffering: the suffering of the native Americans who were killed or driven off their land by European settlers; the pains of slaves brought from Africa by greedy slave traders; the death and poverty of the civil war; the hardships of unemployment and civil unrest in the post-war years and the Great Depression; the many sacrifices of the Civil Rights Movement. 南部的历史是一部苦难的历史：被欧洲殖民者杀戮或驱逐的土著美洲人的苦难，被贪恋的奴隶贩子从非洲带来的奴隶的苦难，内战时的死亡和贫困，战后多年的失业，国内动乱和大萧条，许多人在民权运动中所作出的牺牲等等。
句中的one指的是a history of the South. One常用来指可数名词的单数形式，指同类中的一个。
I lost my pen yesterday. I will buy one tomorrow.
昨天我的钢笔丢了。明天我想再去买一把。这里one＝a pen
本课中But the history of the South is also one of hope and success. 中的one也是同样的用法。
