定语从句1
定语从句(1)
定语从句一．定语从句的定义：所谓定语从句，就是用一个句子来做定语来修饰一个名词，其中被修饰的名词叫做先行词，连接先行词和从句之间（或者说引导定语从句）的词语叫做关系词，关系词分为关系代词和关系副词。
其中常见的关系代词有：that,which,who,whom,whose,as,but,than;常见的关系副词有：why,when,where.（注意：what，how，whether，if和特殊疑问词+ever不能引导定语从句）。
二．如何选择定语从句的连接词：首先明确先行词是什么，然后找到后面的从句，把从句单独拿出来分析，看一看先行词在句子中做什么成分，根据语法选择连接词。
Eg:He tried to escape from the prison that/which was builtin the Middle Age .分析：1.找先行词：prison 2.把prison放入从句中可以看到prison在从句中是做主语，即the prison was built in the Middle Age .而在定语从句中能充当主语的连接词一般情况下是that和which，于是就能选出连接词了。
三．连接词的用法：1.that：可以修饰人和物，在从句中作主语或宾语,表语，做宾语的时候一般情况下可以省略。
Eg: She is a girl who/that has long hair.(在从句中做主语) Is this the news (that)/which you wanted to tell me yesterday?(在从句中做宾语，可以省略that)He is no longer a kind-hearted man that he used to be(在从句中做表语)注意：1）that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：His father died in the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
