37、式的主动表被动,1不定式修饰的名词或代词和不定式逻辑上构成主谓关系时，不定式往往用主动形式。如： Do you have a knife to cut the watermelon ? (A knife cuts the watermelon.) 2不定式和它前面被修饰的名词或代词构成逻辑上的动宾关系，又和该句主语构成逻辑上的主谓关系时，不定式常用主动形式。如： She has a sister to look after. (She looks after her sister.) I know what to do. (I do what.),3不定式作表语形容词的关语，和句中主语构成逻辑

38、上的动宾关系时，不定式多用主动形式，这是因为人们往往认为形容词后省去了for sb. 。如： This book is difficult to understand.

40、e, have been，这些词要保留。如： I havent been to Hong Kong, but I wish to. Are you on holiday ? No, but Id like to be. I didnt tell him the news. 我没有告诉他那个消息。 Oh, you ought to have. 噢，你本应该告诉他的,（四 ）、动名词作主语,动名词或不定式都可以在句中作主语，但在下列句型中常用动名词作主语。 It is / was no use / good + doing sth. It is / was not any use / good +

41、 doing sth. It is / was of little use / good + doing sth. It is / was useless 如：It is no use crying over spilt milk. 覆水难收。 It is of little good staying up too late every day. 每天都熬夜没有什么好处 若主语和表语都是非谓语动词，应保持形式上的一致。 Seeing is believing.
