优质解答
关于代词that和which的用法区别：
在定语从句中,当先行词是指物时,关系代词which可以由that代替,如果which不在介词之后,也可省略.在日常用语或口语中,which不作主语时可以省略.例：
Did you take away the book(which/that）I showed you yesterday?
你把我昨天给你看的那本书拿走了吗?
The hotel at which we stayed was both cheap and comfortable.
我们住的那家旅馆既便宜又舒适.
This is certainly not the book for which I paid./This is certainly not the book I paid for.
