但that 一般可用來代替who， whom， which，作賓格時(shí)可省略
Do you remember the teacher that/who taught us English?
A bookstore is a store that/which sells books.
The man (that/whom/who) you know is a famous professor.
A) that 不能用來替代who， whom， which的兩種情況
1)“介詞+whom/which”的結(jié)構(gòu)中，不能用that
She is a good student from whom we should learn.
2) 在非限制性定語從句中，逗號(hào)后面不能用that
She sang a new song， which we like very much.
注意：非限制性定語從句的關(guān)系代詞不能省略
B) 用that不用which的一些特殊情況
1) 先行詞為all， much， little， something， anything， everything， nothing等
Is there anything (that) I can do for you?
2) 先行詞前有形容詞級(jí)修飾
This is the most exciting report that I have ever read.
3) 先行詞前有first， last， next， only， very， all， any等詞修飾
The first step (that) we are to take is very difficult.
4) 先行詞同時(shí)含有“人”和“非人”時(shí)，用that 不用which，也不用who/whom
He talked about the people and the books that interested him.
C) 關(guān)系副詞when， where， why
用關(guān)系副詞when時(shí)，它的先行詞是表示時(shí)間的名詞，用where時(shí)先行詞是表示地點(diǎn)的名詞，而用why時(shí)它的先行詞只可能是reason，使用時(shí)應(yīng)注意以下幾點(diǎn)：
1) 關(guān)系代詞的選擇主要是看先行詞在從句中所作的成分
This is the city where I was born.
This is the city (which/that) he has visited
I don‘t know the reason why she is late.
That is the reason (which/that) everybody knows
Do you still remember the day when he arrived?
Do you still remember the day (that/which) we spent together?
2) 關(guān)系副詞when，where， why可由“介詞+which”的結(jié)構(gòu)來替代
Is this the reason for which they came?
He left the day on which I came.
注意：how 不能用來引導(dǎo)定語從句
This is the way how he did it.
D) As 作關(guān)系代詞的用法
與the same， such連用
This is the same book as I read last week.
Such books as I have read are classical works.
