is a./n.+doing,no good/no use/such a pity/a waste of time/not an easy task,good/better/foolish/useful/useless/difficult/possible,It is+a./n.+to do,easy/difficult/right/wrong/important/clever/foolish/polite/impolite/pity/honor/shame/odd,3.,如果主语和表语都是非谓语动词，两者应保持同样的形式，或同为不定式，或同为动名词。,A is to B what C is to D.,水对鱼就象空气对人一样重要。,Water is to fish what air is to man.,真题演练,(2001),is not a serious disadvantage in life.,A.to be not tall B.not to be tall,C.being not tall D.not being tall,D.,在,BD,两项中选一项,2.,非谓语动词作宾语,1.to do,和,doing,可作宾语，,done,不行,To do,表未完成或未发生，,doing,表已完成或已发生。,1,）接,to do,的动词：,afford/agree/aim/apply arrange/ask/beg/choose/claim/dare/decide/decline/demand/desire/determine/expect/fail/guarantee/hope/manage/offer/ought/plan/prepare/presume/pretend/proceed/promise/refuse/request/resolve/seek/strive/swear/threaten/undertake/volunteer/wish,等,3)+doing,+to do,都可以的动词，一般无区别,Attempt,begin,can,t bear,deserve,continue,dread,hate,intend,like,loathe,love,need,neglect,omit,plan,prefer,require,start,等，（,P246,章）,如上述动词为进行体，后则接不定式。,I,m starting to work/it,s beginning to rain.,上述动词中,need/want/require/deserve doing,表示被动。,5,）不定式同疑问词一起作宾语（,v.+,疑问词,+to do),时常用的动词包括：,Consider/decide/know/explain/forget/learn/remember/tell/wonder,3.,非谓语动词作补语的要点提示,1.,现在分词表动作正在进行，,过去分词表被动，,不定式表动作已完成或结束,2.,补语如果是非持续性动词，不定式表一次性的动作，现在分词则表示反复发生的动作。,真题演练（,2004,）,The Minister of Finance is believed_ of imposing new taxes to raise extra revenue.,A.that he is thinking B.to be thinking C.that he is to think D.to think,B.,人们认为财政部长正在考虑通过征收新税种来增加政府的额外收入。,4.,非谓语动词作状语的要点提示,1.,不定式和分词都可用来作状语，表原因，让步，方式，伴随，结果等，动名词一般不作状语,2.,现在分词表主动正在进行，过去分词表被动或已经完成的动作。,真题演练（,1998,）,，,he can now only watch it on TV at home.,A.obtaining not a ticket for the match,B.not obtaining a ticket for the match,C.not having obtained a ticket for the match,D.not obtained a ticket for the match,C.,由于没有买到比赛的票，他只能在家看电视比赛了。（作原因状语）,3.,当不定式和分词有自己的主语，构成不定式和分词的独立结构时，不定式的独立结构通常在句中作状语表示伴随，分词独立结构在句中作状语，表示伴随，时间，原因，条件等。,II.,独立主格结构,（一）：独立主格结构的构成：名词,(,代词,)+,现在分词、过去分词；名词,(,代词,)+,形容词；名词,(,代词,)+,副词；名词,(,代词,)+,不定式；名词,(,代词,)+,介词短语构成。,With+n./pron.+doing/done/prep.,With book in hand,主格名词,/,代词,+,分词,/,形容词,/,副词,/,不定式,/,介词短语,(,作逻辑主语,)(,作逻辑谓语,),（二）独立主格结构的特点：,1,）独立主格结构的逻辑主语与句子的主语不同，它独立存在。,2,）名词或代词与后面的分词，形容词，副词，不定 式，介词 等是主谓关系。,3,）独立主格结构一般有逗号与主句分开。,4,）,用分词时表示主动关系用现在分词，被动关系用过去分词；,（三）其作用相当于状语，多用来表示行为、方式或伴随的情况，有时也用来表示时间和条件。这种结构多用在书面语中。,有关独立主格的,2,道专四试题,There _nothing more for discussion,the meeting came to an end half an hour earlier.,A.is B.was C being D have,答案选,being.,With all the data he needed _,Peter began to write his thesis.A collected B.to collect C.collecting D.,答案是,collected,（三）举例：,The test finished,we

home.,工作完成后，我们才回家。,III.,悬垂分词,(,专四应该考不到,超纲,),顾名思义，分词通常通过它的逻辑主语对句子发生作用，如,Looking out of the window of our hotel room,there are lots of mountains.(“,看”的动作由人发出，而主句主语是,mountain),Admired,by everybody,dozens of letters reached the veteran soldier.,Sitting,under an apple tree one night,an idea came to Newton.,Having,eaten our lunch,the car pushed its way through the tortuous canyon.,1.分词充当状语时，分词的逻辑主语和主句的主语一致，即为“分词作状语”。,2.分词充当状语时，分词的逻辑主语和主句的主语不一致，即为“独立主格”。,3.独立主格一般需自带主语。若省去其主语，则为独立主格中的特殊情况，即为“悬垂分词”。,IV.there be,句型中的非限定形式,3.there be,句型中的非限定形式（,P328,）,There to be/there
