定语从句
定语可以由形容词、代词、数词、名词、
分词、不定式、介词短语等来担任，修饰名词。
(以介词短语、分词为例）
例： The girl behind the tree is Kate.
The man driving too fast was drunk（喝醉的）. ➢定语从句
在英语中，修饰名词或代词的句子叫定语从句。
例：The girl who is behind the tree is Kate.
The man who was driving too fast was drunk.
➢关系代词如何引导定语从句
普通代词与关系代词的区别 I have a sister.She works in Shanghai.
2)The room (that) I live in is very big. The room (which) I live in is very big. The room in which I live is very big. The room where I live is very big.
1).先行词是anyone, someone, those时， 关系词使用who
Those who want to go to the Great Wall
sign up here.
Is there anyone who wants to go there? 2).在there be 句型中，先行词指人,关系词 用who
The building
is our school.
The building stands by the river.
The building which/that stands by the river is our school.
先行词 关系词
定语从句
❖which/that 是关系代词，它在从句中代替先
代替 sister 普通代词：只起代替的作用（如上例she)
I have a sister who/that works in Shanghai.
关系代词： （如上例who/that） 1.代替先行词; 2.它还在定语从句中担任一定的成分;
3. 同时连接先行词与它引导的定语从句。 （把主句和从句连起来）
The boy who is strong is Tom
The boy who is clever is Tom
The boy is Tom. The boy is smiling.
The boy who is smiling is Tom.
(主语)
The boy is Tom. The boy has a round faTceh.e boy who has a round face is Tom.
The man to whom I talked is Mr. Li.
关系代词
3.whose 是代词的所有格形式, 它既可以 代人也可以代物。
I saw a woman . Her bag was stolen . I saw a woman whose bag was stolen.
Please show me the book . Its cover is red. Please show me the book whose cover is red.
The boy is Tom. He sits in front of me. The boy who sits in front of me is Tom.

————关系副词
关系副词是用来引导定语从句的，它和关系 代词一样,在从句中代替先行词,在句中作状语。
where:在从句中作地点状语,指代地点. when: 在从句中作时间状语,指代时间。
the red the green the small apple the big
The apple which is red is mine.
The apple which is green is yours.
The apple which is red is small The apple which is green is big.
行词the building, 同时担任从句中的主语，也
起连词的作用，把两个简单句连接 起来。
❖ 关系代词的使用取决于先行词，它们的关系非常密 切，因为关系代词在定语从句中代替主句中的先行词， 所以它在一般情况下都跟在先行词之后，而且它的 人 称、数必须和先行词一致。
关系词判 断 步 骤 :
❖ 首先，要看先行词。 如果先行词是指人,关系代词 可用 who,that,whom,whose。如果先行词指物,关系 代词可用which或that;
2.I’ll never forget the day. I joined the Party on that day.
I’ll never forget the day when I joined the Party. I’ll never forget the day on which I joined the Party .
注意: 固定动介词组不可分割,介词不能提前. 例如:look after,look at …
定语从句中需注意事项 有些情况下只用关系词that,而不宜用which 1.从句所修饰的词又被形容词最高级或序数 词修饰时
This is the most interesting story( that )I
(1) The scientist is very famous in the world. We met her yesterday.
The scientist Ø we met yesterday is very who famous in the world. whom that
(2) The dress is new. She is wearing it. The dress that she is wearing is new. which Ø
(叙述客观事实 用一般现在时) (从句)The woman (who/that) spoke at the
meeting yesterday. (句中yesterday表示过去时间)
the tall
the strong
boy
the clever
The boy is Tom.
The boy who is tall is Tom.
