Answer 1

have除了解释为有、吃、喝以外，还可以组成复合结构，即“have＋宾语＋宾语补足语”。have用作使役动词， 有“请、叫、让”的意思。以下是对你给的三个例句的分析。希望对你有帮助~~

例1，现在分词作宾语补足语：have sb.(sth.)doing)，表示让（使）某人做某事（常指持续性的状态）。
又如，The two men had their lights burning all night long
例2，不定式作宾语补足语，但是不能加to：have sb. do sth，表示让、叫某人做某事。
The soldier had him stand with his back to his father.
以上二个例子意思相近。
例3，过去分词作宾语补足语(have sb. (sth.)done)，表示“使/让/请别人作某事”，表示的动作是别人做的。
I had my hair cut yesterday. (CUT在此是过去分词，头发不是自己理的)
