Question

在什么情况下定语从句中不能用that同上

Answer 1

1)先行词是不定代词：
all,few,little,much,something,nothing,anything等.All that we have to do is to practise every day.
2)先行词被序数词或形容词最高级所修饰.
The first lesson that I learned will never be forgotten.
3)先行词被all,any,every,each,few,little,no,some,等修饰.
I have read all the book (that) you gave me.
4)先行词被 the only,the very,the same,the last 修饰时.
He is the only person that I want to talk to.
5)先行词既有人又有物时.
They talked of things and persons that they remembered in the school.
先行词是表示地点时,要根据从句的谓语动词是及物的还是不及物的.如果是及物的就用that(which),否则用where.
This is the house where he lived last year.
This is the house that (which) he visited last year.

Answer 2

先行词表示物时，关系代词只能用that而不用which的情况如下：
1) 不定代词（all, much, something, everything, anything, nothing, none, the one）作先行词时；
e.g. There is nothing that can be done by us.
2) 先行词被only, any, few, little, no, all, one of, just, very, much等词修饰时；
e.g. The only thing that I can do is to wait. The pen is the only thing that I have.
3) 先行词是序数词或被序数词修饰时；
e.g. This is the first time that I visit Beijing.
4) 先行词是形容词最高级或被形容词最高级修饰时；
e.g. The most important thing that I did is being a good father.
5) 先行词既有人又有物时；先行词既有时间又有地点时；
e.g. The police are looking over the man and his dog that were killed by the tiger.
The time and the place that we will hold the meeting has not been decided yet.
6) 先行词是数词时；
e.g. I bought 3 pens yesterday, now you can find 2 that have broken.
7) 如有两个从句，其中一个关系代词已用which，另一个关系代词宜用that。
e.g. He built a factory which produced things that had never been seen before.

在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物.

非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立

下面为定语从句的引导词：
Connectives (commonly used to introduced Adj. Clause)

1)Relative Pronoun 关系代词
1.Who This is the man who tells me the news.
2.Whose Do you recognize the man whose hat is black.
3.Whom The man whom you want to see is in the office.
4.Which They accepted every plan which is proposed
…… the ship’s log book, parts of which was still possible to read.
5.That The thing that the man needs is knowledge
6.As(before such) This is not such a book as I shall have chosen.
This is the same story as I heard ten years ago.
7.But(= Who not) There was no one present but saw the deed.

(= who did not saw the deed)
2)Relative Adverb 关系副词
1.Where Which is the room where you live？
2.When The month when our National Day takes place is October.
3.Whence I saw the den whence the snake crept out.
很明显：
that 不能作为关系副词，只能作关系代词；
作为关系代词，如果从句已经有 who，whoes，……等等引导（见前面例句），则 that 省去，这点与名词从句很相似，可以一起记。
供你参考。
