1.Our class went on an organized trip last Monday.2.This will be the best novel of its kind ever
.written.3.Who were the so-called guests invited to your party last night?.4.Those selected as committee members will attend the meeting.这几句话中的过去分词做定语分别表示什么意思,过去分词作定语是不是都表示被动或者完成的意思,就这两种意思.另外过去分词做定语和被动语态都有被动的意思,为什么不用被动语态,而用过去分词做定语,区别是什么.这个问题困惑了我很长时间,希望各位老师能解我心中疑惑,先说声谢谢.

答案

Those selected as committee members will attend the meeting
那这个句子来说.有一个原则你需要记住,一个句子不管多么长,结构必须是 主+谓+宾.而且谓语只有一个（除非你用and链接）.就是这里的will attend.主语可以是一堆人,宾语也可以是一堆.但谓语动词就一个.所以如果selected用了被动语态（was selected）,那么就存在两个谓语了.
其实可以这么理解这句话,拆开：
1. they are selected as members
2. they will attend meeting
