呵呵,从句的定义是根据句子成分而言的.
主语里出现一个句子,这个句子就是主语从句.其他以此类推,有表语从句、宾语从句、定语从句、状语从句和同位语从句.一天也讲不完,给你几个简单的例句吧!
例如：
That he is coming here tomorrowhas not been decided yet.
主语从句
My suggestion isthat he should go there at once.
表语从句
I think that he is coming here tomorrow.
宾语从句
The girlwho is here is reading a book.
定语从句
i will be a teacher when I grow up.
状语从句
The news that our team has won is true.
同位语从句
自己找一本语法书看看就OK了.
