初三英语问题

It's impolite to insist on his ______ something.
A、accepting B、accept C、accepted D、accepts

答案是A，请问是为什么？A是名词还是什么词性？详细点~

Answer 1

insist on sth.
doing sth. 这里的ing形式可以理解成是动名词形式，也就是有名词的性质，doing sth.可以理解成是sth. 如 I like reading. 可以理解动名词reading是“读书”，这么一件事情，我喜欢“读书”这事儿。

sb's doing sth. 某人的某行为， 也可以把动名词理解成是名词性质
I like his helping the others. 我喜欢他乐于助人这种行为。

这题目同理， insisit on something
insisit on doing sth.-----insist on accepting something
insist on sb's doing sth------insist on his accepting something

Answer 2

这里的accepting是动名词形式，与它的宾语something一起做介词鸥鸟on的宾语。
