何时可用动名词的一般式代替完成式

当动名词用于admit, confess, deny, forget, recall, regret, remember, report, resent等动词后作宾语时，表示的动作通常发生在主要动作之前——也就是说，这类情况，可以用完成式，也可用一般式，但由于后者显然比前者更简洁，所以，如果不引起意义的混乱，通常会以一般式代替完成式。如：

He admitted stealing [having stolen] the car. 他招认偷了那辆汽车。

He denied telling [having told] me. 他否认告诉过我。

I forgot telling [having told] her the news. 我忘了曾告诉过她这个消息。

He resented being [having been] accused. 他受到指责很生气。

They reported seeing [having seen] UFOs. 他们宣称看见了飞碟。

I don’t recollect [seeing] having seen him before. 我不记得以前见过他。

I remember hearing [having heard] you speak on that subject. 我记得曾听见你谈过这个问题。

He confessed sleeping [having slept] through most of the film. 他承认电影后半部时全睡着了。

I could not recall [hearing] having heard anyone say that before. 我不记得以前听过谁说这样的话。
