We had some friends to dinner last night.

I couldn't get the car to start this morning.

You'll never get him to understand.

黑体部分均为宾语补足语，都符合宾语补足语的结构和语义。第一句是介词短语作宾补，其他两句都是不定式作宾补。此外，作为使役动词，have 和 get 还有一个区别，就是：不定式作宾补时，前者不带 to，后者带 to。

have + 宾语 + 介词短语（作宾补）的例句：

He had done business with Germans; he had them to his house. 

They had this army under his control. 

He will have the car at his disposal for the whole month.
