1. 被动式：当动名词的逻辑主语所表示的是动作的对象时，动名词用被动语态，如：
　He dislikes being interrupted in his speech.
　She is afraid of being left alone.

2. 完成式：动名词的动作发生在谓语动词之前用完成式，如：
　We regret having been unable to inform you of the meeting.
　The students' having done the work so well made us very happy.

　动名词也有完成式的被动语态，如：
　　Some of our customers complained of having been treated rudely.
　　What he had never expected was his having been betrayed（出卖）by his dearest friend.

3. 在动词need, want, require, deserve和介词worth后的动名词不用被动语态，而用主动语态表示被动意思，如：
　The machine needs oiling.
　The exhibition is worth visiting
