關(guān)系代詞which,that,who的區(qū)別
which VS that
which和that都可指代物，有時候可以互換，有時卻是“水火不容”：
一、只用that不能用which的情況：

The most important thing that we should do is to study hard.
我們要做的最重要的事情就是努力學(xué)習(xí)。
(2)被修飾的先行詞為all/ any/ much/ many/ everything/ anything/ none/the one等不定代詞時：
Is there any thing that you want to buy?你有什么東西要買嗎?
(3)先行詞被the only/ the very/ the same/the last/ little/ few等詞修飾時：
This is the same book that I lost.這就是我丟的那本書。
(3)先行詞里同時含有人和物時：
I can remember the persons and some pictures that I saw in the room.
我能清楚記得我在那個房間所見到的人和一些照片。
(4)避免重復(fù)：
Which is the pen that belongs to you?哪支筆是你的?

There is a pen on the desk that belongs to Tom.桌子上那支筆是湯姆的。
