Question

定语从句中which和that有区别吗？

Answer 1

关系代词that与which指物时，往往可以互换，但在下列句中多用that：
1.All that glitters is not gold. 闪光的东西不都是金子。（不定代词包括复合词something 等多后接that）
2.It was the largest map that I ever saw. 那是我所见过的最大的地图。（前有形容词最高级等的先行词之后多用that）
3.It was education that brought about such a big change in his life. 是教育给他的生活带来了如此大的变化。（强调结构用that）
4.Which was the hotel that was recommended to you? 哪一个是推荐给你的旅馆？ (这里用that 显然是为了避免重复which)
5.The room that faces the south is mine. 朝南的那个房间是我的。（that在此表固有的特点）

在下列句中多用which:
6.Beijing, which was China's capital for more than 800 years, is rich in cultural and historic relics. (非限制性定语从句一般皆用which)
7.Larry told her the story of the young airman which I narrated at the beginning of this book. 拉里把我在书本开头叙述过的那个关于一个青年飞行员的故事讲给她听。（离先行词较远时常用which，如在此处用that, 则会有指前面的airman的可能）
8.A shop should keep a stock of those goods which sell best. 商店应存有最畅销的货物。（“those + 复形名词”之后多用 which）
9.This is one of which I'm talking about. 这就是我所讲的那个。（介词之后须用which）
总结：在介词后面或者是非限制性定于从句都用which。

a) 关系代词who的用法
i. who 的前行词必须是人，在从句中可以担任主语，往往也可以代替在从句中担任宾
语的whom,但是它前边不能有介词，如果带了介词就必须用宾格的whom:
（介词+whom）

This is the teacher who teaches us mathematics.
She is the girl who (whom) I met at the party. （可以替代）
She is the girl whom (who) I went there with. （可以替代）
She is the girl with whom I went there. （不可替代）
ii. who，that在很多情况下可以通用，但是有些情况只能用who:
1. 先行词是one, ones, anyone的时候宜用who.
One who has nothing to fear for oneself dares to tell the truth.
The ones who flatter me don’t please me.
Don’t tell anyone about the news who oughtn’t to know it.
Anyone who fails to finish the task given should be criticized.
2. 先行词为those的时候，宜用who为关系代词
Those who were not fit for their work could not see the beautiful clothes
made of the magic cloth.
Those who want to go to the Great Wall sign up here.
3. 当先行词有比较长的后置定语的时候
I met a foreigner in the street yesterday who could asked me questions in
Chinese.
4. 一个句子中带有两个定语从句，其中一个定语从句的关系代词为that,另一个则用
who.
The boy that you met last night is the group leader who studies very hard.
5. 在there be 开头的句子中
There is an old man who wants to see you.
There are many young men who are against him.

关系代词which的用法
在非限定性定语从句中，只宜用which, 不宜用that.
Beijing, which is the capital of China, is a very beautiful city.

在限定性定语从句中which和that在指代物的时候常常可以通用，但是有时只宜用which
而不用that
i. 关系代词前面有介词的时候
This is the hotel in which you will stay.
ii. 如果有两个定语从句，其中的一句的关系词是that, 另一句宜用which.
Let me show you the novel that I borrowed from the library which was newly
open to us.

3. 关系代词与介词，关系代词的省略
a) 关系代词和介词
介词放在关系代词的前面时，介词短语只能用which代物，和用whom代人
This is the hero of whom we are proud.
I want to find the very pen with which I wrote that letter.

当介词放在句子的末尾时，可用that/which代物，that/whom/who来作为介词的宾语，
且这个做介词宾语的关系代词往往忽略

有，很大区别
