人教必修一Unit 4 定语从句之关系代词(原卷版)
第09练定语从句之关系代词定语从句的先行词和关系词在复合句中作定语，修饰主句或主句中某一名词或代词的从句叫定语从句。
定语从句由关系词引导。
限制性定语从句表现为在意义上是先行词不可缺少的定语，若省略，主句的内容就不完整或失去意义；它和主句的关系十分密切，不可用逗号分开。
先行词是被定语从句修饰的名词或代词。
关系词指代先行词，在从句中作一定的句子成分。
引导定语从句的关系代词有which，that，who，whom，whose，as等。
先行词是定语从句修饰和限定的成分，从构成上而言，它可以是名词、代词、名词性短语等；从句子成分上而言，它可以是主句的主语、宾语、表语等。
下面，我们从两个实例来看一下定语从句及其相关成分的分布：1.关系代词that即指人又指物；作主语或宾语（作宾语时可省略）只用于限制性定语从句中，介词后面不能跟that。
当代替物时，可以与which通用。
Yesterday Emily was wearing the new dress that I gave her．昨天艾米丽穿了我送给她的新衣服。
I have a friend that likes listening to classical music我有个朋友喜欢听古典音乐。
2.关系代词which指物；作主语或宾语（作宾语时可省略）在非限定性定语从句中，只宜用which,不能用that.在限定性定语从句中，可用在介词之后。
My parents live in a house which is more than 100 years old我的父母住在一座具有100多年历史的房子里who,whom指人；作主语或宾语（whom常可省略）先行词必须为人。
Who可代替在从句中担任宾语的whom,若前有介词，须用whomA couch potato is a person who spends a lot of time watching TV．“A couch potato”指那种成天沉湎于电视中的人。

2019新人教版高中英语必修一Unit4 语法 定语从句
必修一Unit4 语法定语从句定语可以由形容词、名词、代词、数词、分词(现在分词或过去分词)、副词、不定式(短语)以及介词短语等来充当,也可以由一个句子来充当。
