定语从句中什么时候只能用that~

宜用that，不用which或who，whom的场合
1. 当先行词是不定代词或被不定代词修饰时。如 Tell me everything that you know. / All the people that are working are my workmates.
2. 当先行词是序数词或被序数词修饰时。如 I want the first that looks bigger. / This is the third dictionary that I have used.
3. 当先行词是最高级或被最高级修饰时。如 Tom is the best that I have ever taught. / The most important thing that she can do is to go to bed at once.
4. 当先行词是the only (“唯一的”)，the very (“恰恰；就”)，the just (“恰恰；就”)，the same (“相同的”)，the last (“最后一个”)等或被这些词修饰时。如 The only thing that I need to do is to cook a meal. / He’s the very person that I want to find. / Did you miss the last problem that is in your math test?
5. 当先行词是数词时。如 You can catch the four that are dead.
6. 当先行词作表语时。如 My hometown is no longer the place that it used to be.
7. 当先行词中既有人，又有物时。The young man and his bike that I saw just now are still there.
8. 当句子中含有两个定语从句时，如果其中一个定语从句的引导词用了which、who、whom，则另一个定语从句的引导词用that，以避免重复。 如 The TV set which I bought from the shop that opened last month was broken. / The man who is standing behind the people that are playing cards is my uncle.
9. 当which、who、whom作疑问词，引导特殊疑问句时。如 Which took the camera that was made in Japan? / Who knows the boy that lives upstairs?

望采纳！

首先，定语从句 是限制性定语从句，然后再看 先行词

当 先行词是 all，anything，none，few等 时，连词只能用that
如 Is there anything else that he has left in the room?

当先行词被all,any,no,few等修饰时 ，定语从句的连词只能用that （原理和上面类似）

当先行词被 the only，the last，the very等 修饰时，连词只能用that
如 It was the last train that we were able to take. (it这里做代词，指代鞋子，可以换成this)

当先行词是 最高级或被最高级的形容词修饰时，连词只能用that
如 This is the most beautiful dress that I have ever seen.(that常会被省略)

当 先行词 是 序数词或被序数词修饰时，连词只能用that

如 There are two dogs that bark and fight at the corner of the town every day.

当先行词为并列结构，有人有物，连词只能用that
如 He was glad to talk about the writer and his novels that had impressed him a lot.


一般来说，限定性定语从句中，先行词能用which多数可以用that替换，而可以用that未必能用which

1 非限制性定语从句中不用that
36. Whenever I met her, _______was fairly often, she greeted me with a sweet smile. （09山东24）
A. who B. which C. when D. that 答案B

2 在引导词前有介词的时不用that
41. The schools themselves admit that not all children will be successful in the jobs _______ they are being trained. （05江西25）
A. in that B. for that C. in which D. for which 答案D

1.主句中名词被形容词最高级修饰（the best、the tallest）
2.主句中出现序数词(first、second)
3.非限制性定语从句（即从句与主句用逗号断开）

一、关系代词直接放在介词后面时，要用which。例：
Read the passage to which I referred in my talk.
读一下我在演讲中提到过的那段文章。
His new car, for which he paid ￡7000, has already had to be repaired.
他花700英镑买来的那辆新车已经不得不修理了。

二.which还可以用作关系限定词，后跟名词，that则不能这样用。例：
He changed his mind for the second time, after which I refused ever to go out with him again.
他第二次变卦，以后我再也不跟他出去了。
The postman comes at 6.30 in the morning, at which time I am usually fast asleep.
邮递员早晨六点半就到，而这时我通常还熟睡着呢。
He may come, in which case I'll ask him.
他也许会来，来了我就问他。
There are 2 left, one of which is almost finished and the other of which is not quite.
剩下两件事，一件快做完了，另一件还有得做。

三、引导非限制性定词从句时，一般要用which，不用that。例：
Football, which is a popular game, is played all over the wofld.
全世界都踢足球，它是一项很受欢迎的运动。
She spent all evening talking about her latest book, which none of us had ever heard of.
她花了整个晚上谈她最近的新书，关于这本书，我们没有一个人听说过。
