This is the document which was written by me.
可簡化成==> This is the document written by me.
This is the man who wrote the document.
可簡化成==> This is the man writing the document.
但我看過一種句型 不是Ving和P.P.的分詞簡化 是放「形容詞」時的簡化
This is the document eligible for the application.
原句應該是==> This is the document (which is) eligible for the application.
eligible是形容詞 不是分詞 此時which is可以省略嗎?
