主语补语就是表语 这句话对吗?请帮忙举例说明!急!谢谢!

主语补足语即被动语态中的宾语补足语
举个例子
They caught boy stealing.
boy是caught的宾语,stealing是boy的状态,宾语补足语
把它变成被动语态The boy was caught stealing,此时stealing就成了
主语补足语.
再来看几句主语补足语的句子
The dog is called Karl
The door was painted white.
The glass was found broken.
这些都是.
表语是用来说明主语的身份、性质、品性、特征和状态的
位于be,become,appear,seem,look,sound,feel,get,smell等词之后
Africa is a big continent.
I feel much better today.
Her job is selling computers.
The patient is out of danger.
上面四句分别是名词、形容词、动名词、介词短语作表语
主语补语与表语的一个区别就是：表语是主动的,主补是被动的,但是都是来修饰主语的

某种意义上是对的，请参看这个帖子。
