嘎嘣脆

4）不定式与动名词的逻辑主语和分词独立结构  
1)不定式的逻辑主语为：for +名词(或代词宾格)+ 不定式。例如：  
    I found it impossible for him to do the job alone．我发现他—个人干这活是不可能的。  
    (注)在表示人物性格、特性等的形容词后面，常用of引出不定式的逻辑主语。例如：  
    It was wise of him to do that．他那样做是明智的。  
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。
