2)动名词的逻辑主语为;①人称代词的所有格+动名词;②名词‘s+动名词。例如：
Tom insisted on my going with them.他坚持要我和他们一起去。
He dislikes his wife's working late.他不喜欢他妻子工作得很晚。
3)某些形容词，如：careless等不定式后可以加of来引导出其逻辑主语。这类词主要有：absurd, bold, brave, courageous, careful, careless, clever, wise, foolish, silly, stupid, good, nice, kind thoughtful, considerate, greedy, generous, honest, modest, polite, rude, cruel ,selfish, wicked, wrong等It is very kind of you to help me.你帮助我太好了。
间或也可用for + there to be表示(而且there后面的不定式只能是to be)。
It's a great pity for there to be much trouble in the company.太遗憾了公司里有这么多的麻烦。
