2023年高中英语定语从句语法考试要点及专项练习巩固
定语从句一般由关系代词和关系副词引导
1、关系代词:who, whom, whose, which, that, as
2、关系副词:when, where, why
关系代词和关系副词必须位于从句之首(大家想一想什么叫从句来的? 在一个句子前面加上连词.在定语从句中这个连词叫做关系词.关系词的概念是:既要起连接作用,又要在从句中做成分),主句先行词之后,起着连接先行词和从句的作用, 同时在从句中又充当句子成分。
e.g. She is the girl who sings best of all.(关系代词who在从句中作主语)
The comrade with whom I came knows French.
(whom在从句中作介词with的宾语)
关系词的概念是:既要起连接作用,又要在从句中做成分,那么怎么作这个成分呢(下面的用法要牢记哟):
3、关系代词和关系副词的用法:1)当先行词为人时用who 作主语,whom作宾语;2)当先行词为物或整个句子时用which ,可作主语或宾语;3)先行词为人、物时用that ,可作主语或宾语;4)whose用作定语,可指人或物;5)关系副词when(指时间,在定语从句中作时间状语,where(指地点,在定语从句中作地点状语),why(指原因,在定语从句中作原因状语)。
that定语从句例句
1. He is a good boy. 形容词作定语
2. Two boys need two pens. 数词作定语
3. His son needs Tom's pen. 形容词性物主代词或名词所有格作定语
4. The boy in blue is Tom. 介词短语作定语
5.There is a woman doctor. 名词作定语
6. The boy there needs a bike. 副词作定语
7.There is nothing to do today. 不定式作定语
8. The smiling boy needs a friend. 现在分词作定语
9. A boy called Tom saved the girl. 过去分词(短语)作定语
10. He is the man that I met yesterday. 定语从句
一、定语从句的概念:在复合句中,用作定语的从句叫做定语从句。
二、定语从句的位置:通常位于它所修饰的名词或代词之后。
三、被修饰的名词或代词叫做先行词。
四、引导定语从句的关联词为关系代词和关系副词。关系代词(who, whom, whose, that, which等)在定语从句中可用作主语、定语、宾语等;关系副词(when, where, why等)在定语从句中只用作状语。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。
五、定从基本形式:先行词(名词/代词) + 关系代词/关系副词+ 定从
六、that引导的定语从句
She is the girl that talked to you yesterday. (that作主语)
The coat (that) I put on the desk is blue. (that作宾语)
结论:that引导的定语从句既可以修饰人,也可以修饰物;
that在从句中作主语或宾语;
作主语时不可省略,作宾语可省略。
例如:
1. I like music. I can dance to music.
I like music that I can dance to. (that在从句中用作宾语。)
2. I prefer a sandwich. A sandwich is really delicious.
I prefer a sandwich that is really delicious.(that在从句中用作主语。)
注意:that在定语从句中作主语时,定语从句中谓语动词的单复数应与先行词保持一致.
例如:I prefer movies that are scary.
I like a sandwich that is really delicious.
I love the singer that is beautiful.
I have a friend that plays sports.
as引导的非限制性定语从句

但通常用于像as we allaknow, as
