Question

主语补足语只能用于被动语态么

Answer 1

不是的.
主语补主语,通常位于主语之前或谓语动词之后,当然放在谓语动词被动语态的过去分词之后,
①主语补语位于主语之前,后有逗号
例：Tired and sleepy,I went to bed
②有时位于主语之后,前后皆有逗号
例：Chen,only 1.30 metres tall,won the first prize.
③位于谓语动词之后
例：He died young
He was found died.
④除形容词外,名词、数词、不定式,分词,介词短语,从句也可作主语补足语.
例：He came home quite changed,过去分词短语作主语补足语.
