its subject(to use maynard mack’s categories)is "life-as-spectacle," for readers,diverted by its various incidents,observeits hero odysseus primarily from without;the tragic iliad,however,presents "life-as-experience":readers are asked to identify with the mind of achilles,whose motivations render him a not particularly likable hero. 我想问一下红色的那句话,前面its subject...这句已经是完整句了呀?为什么后面还会出现一个observe呢?这个是个怎么样的结构呀?
