中考网整理了关于2024年中考英语知识点：错省介词by，希望对同学们有所帮助，仅供参考。

　　错省介词by。比如：

　　Who wrote this novel?

　　谁写了这本小说?

　　错误：Who was this novel written?

　　正确：Who was this novel written by?

　　解析：主动句是以who, what, which等作主语开头的特殊疑问句,变为被动句时,介词by不能省略。它可以放在被动结构后面,也可以和疑问代词who, what或者which一起放在句首,但who须用宾格形式。比如：What made you so troubled? =By what were you made to troubled? (你被什么搞得这么心烦意乱的?)
