Question

－Did you talk back to your mother when you were a child?

－Yes. But now I realize I was wrong. I really regret _____ that silly thing to my mum.

A.do                    B.to do

C.doing                 D.did

Answer

C

【解析】

试题分析：句意：——当你是一个小孩子的时候你和你妈顶嘴吗？——是的。但是现在我意识到我错了。我真后悔对我妈妈做那么愚蠢的事。regret to do sth“很遗憾的要做某事”，regret doing sth“后悔做过某事”。根据But now I realize I was wrong.可知此处是对做过的事后悔，故用动名词doing.故选C。

考点：考查动名词的用法。
