主语补足语与宾语补足语的区别

*主补是对一句话的主语进行补充说明.
1.在主语的后面:
eg: Jessica, the best student of our class, won the game.句中the best student of our class是对Jessica的补充说明,让大家明白Jessica的身份.
2.主语前:
eg:Tired and sleepy, I went to bed. ---Tired and sleepy为主补
3.谓语动词后:
eg:He died young. --- young为主补

*宾补则是对句子中的宾语做补充说明.也就是作为动词补语并限制直接宾语的名词、形容词或代词
eg: We call him Jack. 句中Jack是宾补.
