insist to do, insist doing, insist on doinginsist to do, insist doing还是insist on doing？

请看题：Both of my parents insisted _______ a computer for me, but I don’t think it is necessary.

A.

to buy B.

buyingC.

on buying D.

in buying【陷阱】容易误选B，误认为insist后不能接不定式，但可以接动名词。

【分析】答案应选C。

其实，动词 insist 后既不能接不定式也不能接动名词，因为insist 通常用作不及物动词；若语义上需接宾语，要借助介词 on或upon，即用于 insist on [upon] (doing) sth；但它有时的确也可用作及物动词，不过其宾语通常只能是 that 从句，而不能是普通的名词、代词或动名词。

如



He insisted on seeing her home.

他坚持送她回家。

I insisted that he (should) stay.

我坚持要他留下。
