这个帖子好久以前的了啊...不过我也遇到了同样的问题
这里的based on 修饰谁的？如果修饰society前面为什么要有“,”，这样不就可以错误的理解为based on修饰主语the Mochica了吗？可是这样的话逻辑就出问题了.....
啊啊啊啊啊 求大家的帮助啊

过去分词在句尾，除非前面的词是形容词这种不能修饰的情况，否则都是做非限定性修饰前面名词短语和核心词（当然也可以跳跃修饰）。
有逗号是表明“非限定性修饰”。

过去分词也有“非限定性修饰”？...原来都没有听说过，谢谢斑竹的解答^^ 不过还想再问一句，为什么这里是非限定修饰捏~？
只是因为有“，”来判断吗？还是语义上的判断呢？谢谢！！

过去分词做后置定语其实可以看作是定语从句的省略(省略了which + be)。既然定于从句有非限定性修饰，那么过去分词当然也就有非限定性修饰了。
非限定性修饰是从语义上判断的。但是一般情况下（至少根据现在出现过的GMAT里面的题目判断），非限定性修饰前面都是有逗号的。而是不是非限定性修饰也是从逗号上来判断的（除非前面是插入语什么的）。

斑竹呦，想问如何理解上面“前面”二字，如果是SVO的情况，过去分词是只能修饰到O吗？不可以修饰到S?比如下面的第一个例子，based on 不会有歧义修饰到 the Mochica吗？
需要考虑主系表结构的特殊性吗？
下面的两个例子都是摘自OG, 第二个特别说明了“名词短语和核心词（当然也可以跳跃修饰）”这个原则。

其实可以修饰到Subject的，比如句末逗号隔开，用过去分词来形容subject所处的状态。（有时候很难解释全面。比如我在5楼说的其实也只是一个普遍现象，也有它的例外，比如逗号前面是名词，可是依然修饰的是主语，因为逻辑上只能修饰S，无法修饰SVO的那个O。）
不过印象里GMAT中还没见过这样的句子，日常阅读里有见到。
对于这个过去分词，主系表结构没有特殊性。

多谢斑竹指点~~OG 12-56就是这样的例子，请童鞋们自行翻阅~~
