介词加关系代词的介词是怎么来的？

介词是从句中介宾短语结构中的介词。关系代词是代替介宾短语中的名词。所以介词必在关系代词之前。构成:in which, on which,at which, of which,of whom,for which,from which,with whom,with which等。
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.
I want to find the pen with which I wrote the letter
3．Here are the picture-books that the children are looking for .

介词表示 和其他词的关系？

英语介词表示名词、代词等与句中其它词的关系，在句中不能单独作句子成分。用法：介词后面一般有名词、代词或相当于名词的其它词类、短语或从句作它的宾语，表示与其它成分的关系。
介词和介词宾语合在一起构成介词短语。
比如：用作定语
a meeting in the afternoon
下午的一个会议
