专四之非谓语动词(课件).ppt

英语一句话只能有一个主谓结构 如果出现更多动词： 加连词（and / but / so…） 放入从句 变为非谓语动词 非谓语动词功能 时 态 和 语 态 2)有些动词可以要求其后的不定式前面加一个连接副（代）词，一起充当宾语。what，when，where，which，how，whether等，但不可以是why。 Could you tell me whether to go for a picnic? _____ is not a serious disadvantage in life. ( 2001, 51) A. To be not tall B. Not to be tall C. Being not tall D. Not being tall [D]【详解】非谓语动词在句中作了主语。非谓语动词的否定式，要直接在非谓语动词前加not，因此可以直接排除[A]和[C]。动名词和不定式都可以作句子主语，但动名词表示一贯性动作，不定式表示具体的一次性动作。个子不高是一贯的事实，应用动名词形式，所以[D]正确。 there be 非谓语动词的用法 (1)做宾语时取决于谓语动词的接续要求。如： The students expected there to be more reviewing classes before the final exams. (expect要求接不定式做宾语) (2)做除for外的介词宾语，用there being。如： He would always ignore the fact of there being such a contradiction in his inner thought. Ann never dreams of _____ for her to be sent abroad very soon.A. there being a chance B. there to be a chance?C. there be a chance D. being a chance 介词后用动名词，表示存在时必须用there be句型，所以答案为A，这也是动名词复合结构，there为动名词的逻辑主语。 ?I don‘t mind _____ the decision as long as it is not too late. A. you to delay making B. your delaying making C. you delaying to make D. you delay to make Mind要求接动名词,动名词的逻辑主语用形容词性物主代词，答案自然是B。 真题举例 What’s the chance of _____ a general election this year?
