指代person,在从句中充当主语
Which or that
that(那个)具有明确指代性;而which(哪个)具有选择性。因此,当先行词不具备选择性时,关系代词只能用taht。
(1)当先行词是指物的不定代词all, any, anything,
everything, nothing, none, some, little, few, much等时:
All that costs you is just time.
He did everything that he could to prove his loyalty to her.
All和everything包含所有,作为整体看待; some“某种,
某些”,指“具有共同点的一类”;选其中任何一个都一样。
只用that不用which 的情况
Which or that
that(那个)具有明确指代性;而which(哪个)具有选择性。因此,当先行词不具备选择性时,关系代词只能taht。
(2)当先行词被序数词或形容词最高级或the only,
the very(恰恰), the last等修饰时:
The smartest woman that I have ever seen is my mom.
The first thing that I'm going to do is to visit him.
He is the only one that I have confided my secrets to.
只用that不用which 的情况
Which or that

(3)既指人又指物的时候,需要用that:
The patients and their belongings that were still in this
hospital needed to be transferred to another one.
which不能指人
只用that不用which 的情况
Which or that
that(那个)具有明确指代性;而which(哪个)具有选择性。因此,当先行词不具备选择性时,关系代词只能taht。
(3)当主句的主语是疑问词who或which时:
Who is the girl that is smiling
Which is the cover that has grabbed your attention
(which不修饰人)
(which哪一个?已经要求后面指出具体对象,
不再具有选择性)
只用that不用which 的情况
Which or that
只用which 不用that 的情况
which(哪个)引导主句附加信息,只是众多信息的一种,具有选择性。当先行词具备选择性时,只用which。
(1)引导非限制性定语从句,指代前面整个句子或句子部分内容时:
He never failed to meet the deadlines, which made his
editors very proud.
(其他情况可能就不满意了)
Which or that
只用which 不用that 的情况
which(哪个)引导主句附加信息,只是众多信息的一种,具有选择性。当先行词具备选择性时,只用which。
(2)先行词本身是that时:
What's that which just passed behind you
有很多种可能性
Which or that
只用which 不用that 的情况
which(哪个)引导主句附加信息,只是众多信息的一种,具有选择性。当先行词具备选择性时,只用which。
that 不能做前置介词的宾语
(3)关系代词前有介词时:
This is the courtyard in which Lao She used to live.
定语从句的主谓一致
(1)当定语从句的关系代词在从句当中做主语的时候,从句的谓语动词要与先行词在数等方面保持一致。
The book which tells a story about motherhood
became the bestseller of the month.
He makes friends with people who dare say what they
really think.
定语从句的主谓一致
(2)“one of +复数名词”作先行词时,从句的谓语动词通常用复数;当one前面有the only, the very等限定词时,从句的谓语动词要用单数。
He is one of the three students who have passed the
exam.
He is the only one of the three students who has passed
the exam.
