acknowledge后接动词用不定式还是动名词

问题描述

比如下这句：

She acknowledged ________ at fault.

A. to have been

B. having been

是选不定式的完成式还是动名词的完成式？

老师答疑

罗老师：

acknowledge作为“承认, 供认”时，用法和admit用法类似。

admit doing, admit having done sth, acknowledge having done sth 承认做了某事

例如：He acknowledged having made a mistake. 他承认他做错了。

所以上面一题的答案是B。
