问题描述：
Mrs.White showed her students some old maps _________ from the library
A.to borrow B.to be borrowed C.borrowed D.borrowing
我知道答案是C 那么填to have been borrowed行不?
答
不行
答
当mrs white 拿maps 时, 动作已经发生, 故是过去式, 而不是现在过去时 to have been borrowed.
答
不行,这儿是语态问题,只能用v+ed或v+ing
答
原句就算还原也是
some old maps which were borrowed from the library> borrowed
或 which had been borrowed from the library>having been borrowed
