- 关系代词that
- what代替“先行词 关系代词”
- 限定性定语从句与非限定性定语从句
如果先行词是事物或动物，该用什么呢?也用who, whose, whom吗?
代替人的是人称代词，代替事物或动物的是指示代词。同样的，也单有代替事物或动物的关系代词，并且也分为主格、所有格和宾格。
1、定语从句“三段论”：
This is the book.这是本书。
It is very interesting.它非常有趣。
把这两个句子合成一个简练的句子 。
This is the book it is very interesting. (x)
→不能直接将两个句子首尾相连。
This is the book and it is very interesting. (V)
→句子正确，但是不够简练。
This is the book who is very interesting. (x)
→who只能用于先行词是人的时候。
This is the book which is very interesting. (V)这是一本非常有趣的书
→先行词是事物时，应该用关系代词which。
先行词是事物或动物时，用which代替who。
先行词是事物或者动物时，关系代词也分为主格、所有格、宾格：
2、主格关系代词：
（1）先行词是事物：
This is the letter.
It arrived yeterday.
This is the letter it arrived yesterday. (x)
This is the letter and it arrived yesterday. (V)
This is the letter which arrived yesterday. (V)这是昨天到的那封信。
(2)先行词是动物
I like the cat.我喜欢那只猫。
It has blue eyes.它有蓝色的眼睛。
I like the cat it has blue eyes. (x)
| like the cat and it has blue eyes. (V)
I like the cat which has blue eyes. (V)我喜欢那只有蓝色眼睛的猫。
先行词是人，人称代词是主格形式，就用who,先行词是事或物，人称代词是主格形式，就用which
3、所有格关系代词
事物或动物的所有格和人的所有格，都用whose
(1 )先行词是事物
This is the table.这是那张桌子。
Its leg was broken yesterday.它的桌腿昨天坏了。
This is the table its leg was broken yesterday. (x)
This is the table and its leg was broken yesterday. (V)
This is the table whose leg was broken yesterday. (V)
这是昨天桌腿坏了的那张桌子。
(2)先行词是动物
I love the cat.我喜欢那只猫 。
Its hair is black.它的毛是黑色的。
I love the cat its hair is black. (X)
I love the cat and its hair is black. (V)
I love the cat whose hair is black.(V)
另外，先行词是事物时，也可以用of which代替whose。
I love the cat whose hair is black. (V)
= of which the hair (不加the是错误的)
= the hair of which
I love the cat of which the hair is black.(V)
所以，事物的所有格关系代词既可以用whose,也可以用of which。
3、宾格关系代词
先行词是人时，宾格关系代词用whom;先行词是事物或动物时，宾格关系代词用which。
This is the car.这是那辆小汽车。
I bought it yesterday.我昨天买的。
将这两个句子合在一-起。
This is the car I bought it yesterday.(x)
This is the car and I bought it yesterday. (V)
This is the car which I bought yesterday. (V)这是我昨天买的小汽车。
