Why do sth. ? 二、不定式的主动和被动 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 cut

39、s 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. 。 This book is difficult to understand. This kind of fish is n

Are you on holiday ? No, but Id like to be

42、. I didnt tell him the news. Oh, you ought to have. 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 + 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 li
