什么是(动词不定式做补语)

i want you to speak to him. 不定式做的应该也是宾补（宾语补足语）
这个句子中，you是宾语

不定式做宾语的句子：
i want to sleep.
i promise to wait.

作补语：
he asked me to try again.
they invited me to go with them.

两个句子中的me都是宾语，后边的不定式成分是补语。

he asked me to try again.
they invited me to go with them.
像这种谓语动词后面有了宾语了跟在宾语后面的就是补语.也就是补充说明前面的.
