题目没写错吗?A-D都不对啊?我猜原题是“In the bag he found a piece of paper on which some special words were written”之类的吧,答案是B,是由“write some special words on a piece of paper”转换而来的……...不好意思，题目是In the bag he found a piece of paper___some special words。A 。which was writtenB.on that were writtenC.on which were written D.on it were written可是A可以理解成：纸被写了些字啊嗯，从中文来理解是没错，但是有时候是不能这样直译理解的，英文里不会说“write paper”，必须是“write on paper”，像楼上说的，需要一个介词“on”~
