什么是宾语补足语?

在句中补足说明宾语的成分叫做宾语补足语.通常放在宾语的后面.宾语补足语主要有以下形式:

1.形容词 eg: Keep the baby warm.
Don't get your clothes dirty.
The news made me excited. 这里excited 就是me 的宾语补足语
注意:形容词作宾语补足语,只用在某些动词之后,如keep保持, get使, think认为, find认为, make使, push推.

2.动词不等式 eg: Mum always tells me to study hard.
I'd like to have a rest now.
注意:动词不定式作宾语补足语,只用在某些动词之后,如tell告诉, want想要. wish希望, would like想要, get使, ask要求, teach教

3.现在分词. eg: I heard someone singing in the next room.
Look!Can you see a boy running towards us?
注意: 现在分词作宾语补足语,只用在某些动词之后,如see看见, hear听见, feel感觉, watch看等感官动词.

4.名词 eg: They call him Jim.
The parents named their baby Sanmao.
注意:名词作宾语补足语,只用在某些动词之后,如make使得, call称呼, name命名等.

具体概念很难说阿。。我就举个例子来阐释1下吧。。
I saw you stand(ing) at the door.
这句话I是主语，saw是谓语，you是宾语，stand(ing) at the door就是传说中的宾语补足语了，它的功能想必顾名思义了吧。。
宾语补足语通常紧跟在宾语之后，可以充当宾语补足语的大致有：动词非谓语形式[如不定式，动词原形，现在分词，过去分词。。]，形容词，副词，介宾短语。。。
