夏：谜。夏朝的资料太少，谜太多，需要将来慢慢一一去解开。商：纣。纣就是残暴的意思，纣王大家都知道。话说商朝最喜欢用活人祭祀，十分残忍。周：礼。周公创周礼，一直融入儒家到现在，礼已经是作为中国人不可缺少的一部分了。秦：统。本来想用暴，但是秦对于中国后世来说意义非凡，还是统字合适些。
原文是:It was the best of times， it was the worst of times， it was the age of wisdom， it was the age of foolishness， it was the epoch of belief， it was the epoch of incredulity， it was the season of Light， it was the season of Darkness.
