定语从句 U9 掌握 who、whom,that、which,whose 引导的限制性定语从句。 定语从句(定义):在复合句中,修饰某一名词或代词的从句叫做定语从句。定语从句可以分为限制性定语从句和非限制性定语从句。 如:I like music 主句 that I can dance to 从句. 剖析定语从句: 定语从句就是这个句子是由两个句子组成,前面的句子叫主句;关系代词后面的句子叫从句。 以此句为例:I like music 是主句。那么I can dance to 就是从句. 何为先行词: 先行词:被定语从句所修饰的名词或代词称为先行词。 根据定义可知,先行词就是主句结尾的名词或者代词。 如:I like music 主句 that I can dance to 从句. 那么先行词就是主句里面的名词或者代词。那此句先行词就是 I like music. 那先行词就是music。 关系代词:引导定语从句的关联词称为关系代词。 关系代词在定语从句中有三个作用: (1)引导定语从句; (2)代替先行词; (3)在定语从句中充当一个成分。 关系代词 例句 that 在从句作主语或宾语 指物或指人 I love movies that are educational.(作主语) That’s Ella that is a bit fat. (作主语) Everything that you learn becomes a part of you and changes you. (作宾语语) Which 在从句中作主语或宾语 指物 The bag which is on the desk is mine. (作主语) I prefer music that I can sing along with. (作宾语) Who在从句中作主语或宾语 指人 I love singers who write their own music. (作主语) The man ( who/ whom/ that ) he described just now is a famous writer. (作宾语) who / whom / that 作宾语:( 可省略) Whom在从句中作宾语 指人 The girl to whom you just spoke is Mary. (作宾语) Whose在从句中作定语 指人和物 The girl is Mary whose hair is yellow. (作定语) My favorite singer is quite famous whose name is Jayzhou. (作定语) 【总结】 1. 当先行词表示人时,引导定语从句的关系代词用 that 或 who,whom; 2. 当先行词表示物时,引导定语从句的关系代词用 that 或 which。 2. 当关系代词在定语从句中充当主语时,关系代词不能省略;当关系代词在定语从句中充当宾语时,关系代词可以省略。 即学即练 1.We all miss Wu Mengchao _saved thousands of lives in his medical work.
