所修饰的先行词后,有限制性定语从句和非限制 性定语从句两种。定语从句由关系代词或关系副 词引导,相当于一个(长)形容词,所以又称为 形容词性从句。

Unit4 单元语法 定语从句讲解素材 人教版高一英语必修第一册
新人教高一英语必修一U4 Natural Disasters 语法定语从句一.定义:定语是用来修饰名词或代词的,起限定作用的成分。
定语可以由形容词、名词、代词、数词、分词(现在分词或过去分词)、不定式(短语)、介词短语等来充当,也可以由一个句子来充当。
充当定语功能的句子就是定语从句。
二、定语从句三要素1. 先行词:被修饰的名词/代词/整个主句2. 关系代词:连接先行词与定语从句(that, which, who, whom,whose)3. 关系副词:连接先行词与定语从句(where, when, why)注意:关系代词/副词的选择→看定从是否完整句子完整→用关系副词缺少成分→用关系代词定从=先行词+关系词+从句例:I know the girl. The girl is in red. (两个简单句)→I know the girl who is in red. (定语从句)例句中被修饰的词是the girl, 这个词就称为先行词。
其中连接两个句子的是who,称为关系词。
关系词在从句中指代先行词,并在从句中充当一定的成分,观察上句,关系词在从句中充当主语。
☆总结:关系词有三个作用:(1)连接定语从句; (2)、指代先行词;(3)、在从句中充当成分关系词的用法如下表:三、关系代词的用法:定语从句中缺少主语、宾语、表语、定语用关系代词。
在从句中作宾语时,关系代词常可以省略。
1.that的用法that指人或物,在定语从句中可作主语、宾语或表语,但that不用于引导非限制性定语从句。
例:The letter that I received was from my father.The girl that has long hair is my sister.The city is no longer the one that it used to be.注意:用that不用which的情况2.which 的用法which指物,在从句中作主语或宾语。
