什么是同位语从句?在复合句中用作同位语的从句称为了同位语从句,同位语从句一般由that,whether等连词引导,常放在fact,news,idea,truth,hope,problem,information等名词的后面,说明该名词的具体内容。同位语从句的引导词主要由以下几种:

第一、由that引导的同位语从句

第三、由when引导的同位语从句

要注意同位语从句和定语从句的用法的区别

同位语从句其形式与定语从句相似,二者之前都有先行词,但与先行词的关系不同:同位语从句与先行词同位或等同,是对名词加以补充说明,定语从句则与先行词是修饰关系,试比较

同位语从句一般紧跟其先行词之后,但有时也可与先行词分开,置于句末,如:

采纳新规则的建议是主席提出来的
