简单句之 主谓双宾 和 主谓宾宾补
1. 主+ 谓+ 间宾 + 直宾
I made Tom a cake.
= I made a cake for Tom.
I bought my mother a bag.
= I bought a bag for my mother.
2. 主+ 谓 + 宾 + 宾补
I find English easy.
I find her an angel.
区分这两种结构：
I made John our chairman.
I made John a cake.
方法很简单：在宾语后加上be动词， 若能构成完整句子，则是补足语。
比如我们可以说John is our chairman. 所以上句中的our chairman是宾语补足语。无法构成完整的句子，则为直接宾语。比如我们不能说：John is a cake. 所以a cake 是直接宾语。
