对于楼主的这句:here is an example,which i heard at nurses' convention ,of a story which works well because the audience all shared the same view of doctors,
第一个which修饰a story,将which前置起强调作用(实为倒装)正确的顺序应该是of which(句子中把of和which了,是一种定作手法,使整个句子看起来有文学点).I heard at nurses'convention是谓语部分.这部分是一个主语从句.普通的写法即为:a story which I heard .(第一个which引导主语从句,用of which避免和下面的a story重复）
正常顺序而且简单的句子应该是:Here is an example,of which(指a story) I heard at nurses' convention,a story which works well because the audience all shared the same view of doctors,
再明显一点的话就是：
Here is an example,a story,which I heard at hurses' convention,which works well because the audience all share the same view of doctors.这样整理一下句子更简单,没有太多修饰便于理解,但缺少写作手法,不算文学了.
因此不难看出,第二个which引导story为主语的宾语从句.去掉点缀的句子,宾语从句部分应该是:a story,(which I heard from nurse's convention 谓语部分）,which works well .(宾语部分)
楼下的兄弟别情绪化,本人分析的如何?我相信应该没有错的.
