二句合一
1. I saw the man. He closed the door I saw the man who /that closed the door 2.The girl is happy. She won the race The girl who /that won the race is happy 3.The man called the police . His wallet was stolen The man whose wallet was stolen called the police

❖ 然后，要确定关系词Biblioteka Baidu从句中的成分。请看下表
先行词 人 物
主语 who, that which, that
宾语 who(m), that which, that
定语 whose whose, of which
用适当代关系词填空

✓Whom /that作定语从句的宾语
The woman（ whom/that) they wanted to visit is a teacher.

作宾语
注意: 关系代词作动词宾语时可省略.

6.Which is the bike that you lost? 7.Who is the woman that was praised at the
meeting?
II.只能使用which 的情况
1.关系代词前有介词时； 2.先行词本身是 that 时； 3.非限定定语从句 口诀:要有which别着急，
• A. which B. that
C. /
D. it
• 6. The girl handed everything _____ Cshe had picked
up in the street to the police.
• A. which B. in which C. that D. all
※7. _____Ccleans the blackboard should be praised.
Ⅰ、限定性定语从句：从句不可少，没有 它，先行词的意思不明确，主句也不完整。 与先行词之间不用逗号。
e.g:This is the book that/which I want.
Ⅱ、非限定性定语从句：是对先行词的补充 说明，没有它不会影响先行词或主句意思 的完整性。 从句一般用逗号同主句分开。
e.g:Mr. Green， who is watching TV，is my uncle.
➢ 定语从句关系词的确定:
a.先行词的分类 b.先行词在从句中充当的成分
人：who/that
1.先行词做主语 物：which/that
2.先行词做宾语
人：who/whom/that
物：which/that
3.先行词做定语 人：whose 物：whose/of which
4.先行词做状语：when, where, why
➢(限定性)定语从句的结构
Mary is a girl who has long hair.
先行词 关系词 定语从句
关系代词
关系副词
which, who, whom, Where, when,
whose, that
why
➢定语从句的实质：二句合一
（合并条件：人物先行在句一，又占句二一席地）
Mary is a girl.
(3)先行词为数词或被序数词（含 last)修饰时。 （4）先行词是并列词组既有人又有物时。
(5)在以who, which开头的句子中为了避免重复。
口诀：不定代词这一伙，全用that准没错 先行词前有修饰，千万不能用which.

定语从句：在复合句中修饰名词或代词的
句子， 叫定语从句。
先行词：被定语从句修饰的词叫先行词。 关系词：引导定语从句的词叫关系词。

3. The man _w_h_o_s_e_ leg broke in a
