中国大学MOOC: 下面这段话是安东尼在凯撒大帝葬礼上的演讲，出自莎士比亚的《凯撒大帝》。其中的“He”指的是Brutus,而“me”就是Antony。在演讲中，安东尼表面上是竭尽恭维地赞同布鲁特斯，再三称他们为“honorable man”，但是话中之音都是指控布鲁特斯等人的杀人之举。我们可以感受到安东尼在演讲时的激情澎湃。果然，这种具有“讽刺”意味陈述的煽动性使得罗马市民最终揭竿而起。请问文中的讽刺效果是通过什么手段来实现的？He was my friend, faithful and just to me; But Brutus says he was ambitious,And Brutus is an honorable man. ...I thrice presented him a kingly crown, Which he did thrice refuse. Was this ambition?Yet Brutus says he was ambitous;And sure he is an honorable man.
