Question

当定语从句的主语和主句的主语一致时的省略

He was trying to find a room in which he could keep all his goods.
He was trying to find a room in which to keep all his goods.
为什么变成TO KEEP，不应该连引导词也一起省略么？

Answer 1

后者叫带疑问词的不等式，不是定语从句的省略

Answer 2

原来的定语从句变成了含疑问词的不定式
如果介词放到不定式后，可以省略which
He was trying to find a room to keep all his goods in.

那不应该连引导词也省掉么

追答

如果介词放到不定式后，可以省略which.在前面就不能省。
定语从句不也是这样吗？

追问

那这句You make me want to do 这句是me (That i )省略了主语和引导词吗

追答

你见过make后跟宾语从句的？

追问

可是我之前看了一个句子是you make me want to do....

追答

这是 want to do做宾语补足语。

make sb do sth,(这个合理)

追问

嗷 定从的话引导词前有介词的话就不能省略吗

追答

是啊。介词在引导词前就不能省，介词放到后面，就可以省略。

Answer 3

第二个句子就是错误的
