问题：英语被动分词中过去分词能表被动，但是没有be，例如Mostoft 
分词中过去分词能表被动，但是没有be，例如Mt of the people invited to the party were famous scientists.  被动不是be加过去分词么
回答：全句可以用还原的方式看：
Most of the people （who were ）invited to the party were famous scientists.

invited to the party是被动意义的过去分词短语，修饰先行词Most of the people 。这是可以看成是who引导的被动结构的，英语为了避免大量的定语从句，而是用过去分词短语作后置定语，这是可以理解的。
