分别举个例子:
宾语从句:
i don't know what to do.i don't know which one is the best.象这种有what\which\that引导句子在整个句子充当宾语成分。。。那就是宾语从句。 主语:i 谓语:don't know 宾语:what to do.
定语从句:
i don't know the man who is wearing a pair of glass.象这中由who, which, that,when 引导的句子在整个句子中做定语成分就叫定语从句。
主语:i
谓语:don't know
宾语:the man
定语:who is wearing a pair of glass.修饰the man.
状语从句:
i don't know she is my english teacher when i see her at first time.我第一眼见到她的时候,不知道她是我的英语老师。
象这样以when引导的句子在整个句子中充当状语成分的就是状语从句。
主语:i
谓语:don;t know
宾语:she is my english teacher.
状语:when 引导的句子。
