分词作状语和定语的时候该怎么区分?
这是做阅读时文章里的一个句子：
When the album Thriller was released in 1982,it was played endlessly on MTY turningJackson into a true crossover artist,crossing the world of black and white music in ways that millions could relate to.
答案给出的解析是：【现在分词短语turning Jackson a true crossover artist 做结果状语 crossing the world of.是现在分词短语作定语修饰crossover artist 相当于一个非限定性定语从句.】
我的疑问是 分词作结果状语从句为什么没有逗号?分词作后置定语却带了逗号?
还有就是我自己写的句子：1.The study,conducted by Mrs,is seeking for the true reasonof such phenomena.2.The study conducted by Mrs is seeking for.3.Conducted by Mrs,the study is seeking for.
我的理解是：3句当然是分词作状语 2句是分词作后置定语 那么1句呢?是定语还是状语?该怎么区分理解此类结构句子?

第一句是分词做非限制性定语相当于一定语从句，改写为The study ,which was conducted by Mrs,is seeking for the true reason of such phenomena.
你所问的定语和状语逗号的问题。非限制性定语要用逗号和句子的其它部分隔开。结果状语可用逗号隔开也可不用。
