錯省介詞by。比如：

Who wrote this novel?

誰寫了這本小說?

錯誤：Who was this novel written?

正確：Who was this novel written by?

解析：主動句是以who, what, which等作主語開頭的特殊疑問句,變為被動句時,介詞by不能省略。它可以放在被動結構后面,也可以和疑問代詞who, what或者which一起放在句首,但who須用賓格形式。比如：What made you so troubled? =By what were you made to troubled? (你被什么搞得這么心煩意亂的?)
