就是那些in which,with which……关于有which 的定语从句,我真的分不清怎么使用.还有,我不知道英文到底

你会使用which吗,举个例子吗吧.
this is the house which I lived in for seven years .
this is the house in which I lived for seven years.
我觉得就类似于介词前置一样嘿嘿……谢谢哦！那比如： The way with which you will go about the task really matters.这句话是哪个介词前置了呢？这句话可以分开来开把定语从句提出来，thewaywith whichyou willgoabout the task,这里面介词就是with
