主句和从句的主语一致时,从句的被动语态如何表达

Answer 1

当主句和状祥帆语从句的主语一致时，从句主语的可以省略，同时从句的谓语动词要变成非谓语动词中的分词则宴敬。如果从句是主动语态，用现在分词；如果是被动语态，用过去分词。
以 when为例：
I'll call you when I get there. 可以改写为 I'll call you when getting there. （我一到那里就给你打电话）【主动】孙慎
I'll start to think about it when I have to write my report. 可以改写为 I'll start to think about it when having to write my report. （我要写报告时会对此予以考虑的）【主动】
When the doors are blown by wind, they always rattle. 可以改写为 When blown by wind, the doors always rattle.（只要被风一吹，门总是吱嘎作响）【被动】
