定语从句 两个句子合并一个句子,这两个句子怎么分辨从句和主句?
She is reading a reaport.
The report is about a story.
合并后，能不能是she is reading a report that is about a story.
那The report that she is reading is about a story.这个是不是也对啊？

答案

有先行词+关系词的部分是从句 .(定语从句的概念:在复合句中,修饰某一名词或代词的从句叫做定语从句.被修饰的名词或代词叫做先行词,定语从句一般放在先行词的后面.）
如:1.report that a about a story
2.the report she is reading
1.report 作从句主语
2.report 作宾语
