一道英语题目

定语从句中为什么会有介词＋关系代词的用法，是怎么来的！！！

Answer 1

关系代词与介词
介词放在关系代词的前面时,介词宾语只能用which代物,
和whom代人。(介词在末尾时,关系词可以省略)
1)This is the hero( whom) we are proud of.
This is the hero of whom we are proud .
This is the hero(that) we are proud of .
2)She is the girl whom I went with there.
She is the girl with whom I went there.
She is the girl that I went with there.
She is the girl 省略 I went with there.
注意: 固定动介词组不可分割,介词不能提前.例如:look after,look at …
1．The room (that) I live in is very big.
The room (which) I live in is very big.
The room in which I live is very big.
2. I want to find the pen (that) I wrote the letter with.
I want to find the pen (which) I wrote the letter with.

3．Here are the picture-books that the children are looking for .
