with which和to which的用法区别？
which和to which的用法区别？
区别就是两者都是介词 which 引导的定语从句，具体不同如下，
with whichThe Pentagon has said it will give preference to companies with which it can do business electronically.五角大楼已经宣布它将优先考虑能与之进行电子交易的公司。, to which这些要看后面从句中不及物动词的具体意思而定不是不及物动词的后面没加介词，而是把这些介词提前了， 提到了which的前面因为英语的习惯是先表明要表达的意思，有时候句子很长，所以把介词提前，避免头重脚轻，
例如
定语从句介词加which的用法？

This is the house in which Tom lived many years ago.
is the reason why he was late for the meeting.

inwhich和withwhich区别？
which和in which用法的区别为：意思不同、用法不同、词性不同。
一、意思不同
1、which：哪一个，哪一些。
2、in which：在其中。
二、用法不同
1、which：which用作关系代词，可引导限制性定语从句或非限制性定语从句，引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。
2、in which：in which用于定语从句，作关系副词，在句中不做成分，in whichwhere。
三、词性不同
1、which：which是关系代词或关系形容词，作为代词用作主语或宾语，作为形容词用作定语。
2、in which：“介词短语 which”属于副词性，只能用作状语。
