(1) 先行词是不定代词all ,few,little,everthing ,nothing anyting,none等。如：
Is there anything that you want to buy in the shop?
你在商店里有什么东西要买吗？

This is the best movie I’ve ever seen.
这是我看到过的最好的一部电影。
(3) 先行词被all, any ,every ,each, few,little, no ,some等修饰时。如：
I have read all the books(that )you gave me.我读了你给我的所有的书。
(4) 先行词被the only , the every ,the same, the last 修饰时。如：

他就是我要谈话的那个人。
(5) 当并列的两个先行词分别表示人和物时。如：
They are talking about thins and persons that they remembered.
他们在谈论他们所能回忆起来的人和事。

这个国家建立了一个工厂，生产以前未曾见到过的东西。
(9) 主句以there be开头。如：
This is a seat in the corner that is still free.那个角落还有个座位空着。
定语从句 - 介词+关系代词引导的定语从句

(2) The school in which he once studied is very famous.
(3) Tomorrow I will bring here a magazine (that/which) you asked for.

(1) This is the watch which/that I am looking for. (T)
(2) This is the watch for which I am looking. (F)

(1) The man with whom you talked is my friend. (T)
(2) The man who/that you talked with is my friend. (F)
(3) The plane in which we flew to Canada is very comfortable. (T)
(4) The plane in that we flew in to Canada is very comfortable. (F)
