第五章非谓语动词 【非谓语动词作状语】 一.不定式,分词作状语的基本原则 不定式,分词作状语时,不定式,分词的逻辑主语必须与句子的主语保持一致,即不定式,分词作状语时必须和句子的主语保持一致,即不定式,分词作状语时必须和句子主语含有逻辑上的主动或被动关系,否则一般不能使用不定式,分词作状语. 二.不定式作状语 1.不定式作目的状语 不定式作目的状语的情况比较多,如果强调目的性时,不定式前还可加in order或so as,构成"in order to do"或"so as to do"结构."in order to do"结构作目的状语时,可以放在句首也可放在句中;"so as to do"结构只能放在句中. Her mother plans to fly to Beijing at least four times a year(so as/in order)to visit her. Bob took down my telephone number so as/in order not to forge t it. 2.不定式作结果状语 不定式作结果状语常用在下列句式中:so...as to;such...as to;...enough to;only to(常表示以外的或事与愿违的结果);too...to等. I'm not so stupid(a fool)as to write it down. Jane hurried back only to find that her mother had left. I'm too tired to stay up longer. 备注:在only too..to结构中,too...to...并非是"太....而不能..."之意.此时,与too..to..搭配的形容词常见的有pleased,ready,willing,glad,happy等. I'm only too glad to have passed the exam. 3.不定式作原因状语 形容词作表语时,后面可接不定式作原因状语,用以说明产生这种情绪的原因.用于这类结构中的形容词常见的有:happy,glad,sorry,anxious,proud,disappointed,angry,surprised,ready,delighted,pleased等. You will never know how happy I was to see her yesterday. 4.在"主语+系动词+表语(形容词)+to do"结构中,句子的主语与动词不定式有逻辑上的被动关系,且形容词表示主语的特征或性质,这时,需用不定式的主动形式表示被动意义.该结构中常用的形容词有:easy,hard,difficult,important,impossible,interesting,pleasant,nice,comfortable,safe,dangerous等. This question is easy to answer. This book is difficult to understand. 三.分词作状语 1.分词作状语时其形式的选择 2.分词作状语的句法功能 分词作状语时,可以表时间,原因,结果,条件,让步,行为方式,伴随状况等.为了强调,还可与 while,when,once,if,unless等连词连用. When offered help,one often says"Thank you"or "It's kind of you".(时间) Separated from other continents for millions of years,Australia has many plants and animals not found in any other

高中英语非谓语动词用法详解及练习(含答案详解)

非谓语动词 非谓语动词(一)——动词不定式 动词不定式、分词(现在分词,过去分词)和动名词统称为非谓语动词。现代英语将现在分词和动名词合为一大类叫作v + ing形式。这些动词的形式不能在句中单独作谓语用,因而没有语法主语。但可以有逻辑主语。由于没有语法主语,也就不受人称和数的限定,因为不是谓语,也就没有时态和语态,但这些词仍能表示动作和状态,所以仍有表示与其他动词相对时间关系的形式。由于与其它词有逻辑上的主谓关系,因此也有表示主、被动的形式,同时也有自己的宾语和状语,一起构成非谓语动词的短语(动词不定式短语,分词短语,动名词短语)。动词不定式、过去分词及v-ing形式在句中均不能作谓语用,所以叫做非谓语动词。 (一)动词不定式:动词不定式由―to+ 动词原形‖构成,如:to study, to play,动词不定式虽然不能作谓语动词用,但仍留着动词的特征,它可以带有所需要的宾语或状语而构成动词不定式短语,如:to study hard, to play table tennis。 2、动词不定式的基本用法:动词不定式能起名词、形容词和副词的作用,可在句中作主语、表语、宾语补足语、定语和状语用,如: (1)作主语:To help each other is good.(动词不定式作主语时,一般可用it作形式主语,而将作主语的动词不定式置于句末,如:It is good to help each other. (2)作表语:My job is to drive them to the power station every day. 动词不定式在系动词be之后作表语,与表示将来时的be + 动词不定式结构有所区别,如:Our plan is to set up another middle school for the peasants’ children.我们的计划是给农民子弟再成立一所中学。(句中的谓语动词为is,动词不定式to set up… 为表语,主语为plan,但plan并不是动词不定式的逻辑主语,即动词不定式to set up所表示的动作不是主语plan产生的。)We are to set up another middle school for the peasants’ children.我们将为农民的子弟再成立一所中学。(句中的are to set up整个结构为句中谓语,主语为we,同时也是动词不定式to set up所表示的动作的逻辑主语,即动词不定式to set up所表示的动作是由we产生的)。 (3)作宾语:①作及物动词的宾语,如:She wishes to be a musician.;②作某些形容词的宾语:可以有动词不定式为宾语的形容词一般有glad, sorry, afraid, pleased, determined, willing, eager, anxious, ready, sure等,如:I am determined to give up smoking.;③动词不定式一般不作介词的宾语,但动词不定式之前如有疑问词时,就可作介词的宾语,如:Can you give us some advice on what to do next? (4)作宾语补足语,如:Tell the children not to play on the street. 如果句中的谓语动词为see, hear, watch, notice, have, make, let等,作宾语补足语的动词不定式须将to省去,如:I saw a little girl run across the street. (5)动词不定式在句中作宾语,如带有宾语补足语时,须先用it作形式宾语,而将该动词不定式后置,如:I don’t think it right to do it that way. (6)作定语:动词不定式作定语时,须位于被其修饰的名词或代词之后,如:Is this the best way to help him? 和定语用的动词不定式如果是不及物动词,不定式后面就要用必要的介词,如:He is the man to depend on. 如果被不定式修饰的名词为place, time, way,不定式后面的介词,习惯上可以省去,如:The old man is looking for a quiet place to live. (7)作状语:动词不定式可以作下列的状语:①目的状语:Every morning he gets up very early to read English. 为了强调不定式表示目的的作用,可在不定式前加in order to或so as to(以便或为了),但应注意in order to位于句首或句中均可,而so as to不能位于句首,如:She reads China Daily every day in order to (so as to) improve her English. 将表示目的的不定式置于句首,也可强调目的的作用,如:To master a foreign language, one must work hard at it. ②结果状语:They lived to see the liberation of their home town.他们活到亲眼见到了他们家乡的解放。③too + 形容词或副词+ 动词不定式,表示―足能…‖的结果,如:You are old enough to take care of yourself now. 3、复合结构不定式:由for + 名词(或代词宾格)+ 动词不定式即构成复合结构的动词不定式。其中for

高中的英语非谓语动词讲解-(整理)

非谓语动词 非谓语动词包括不定式(to do)、动名词(-ing)、现在分词(-ing)与过去分词(-ed)。它们不受主语人称和数的限制,在句子中不能充当谓语,但可以充当句子的其他成分,并且有时态和语态的变化。 动词不定式

定义:动词不定式是非谓语动词的一种,它没有人称和数的变化,在句子中不能独立作谓语,但它仍保持动词的特点,可以有自己的宾语和状语。 一、不定式的意义 1. 不定式的一般式:一般式表示的动作或状态发生在谓语动词表示的动作或状态的同时或之后。当不定式的逻辑主语是这个不定式所表示的动作的承受者时,不定式一般要用被动式(to be done). eg: He seemed to be tired. The building to be finished next month is for our teachers. 2. 不定式的进行式:进行式表示动作正在进行,与谓语的动作同时发生。 . When I went to his home, he happened to be traveling around the world. 3. 不定式的完成式:如果不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前,就用完成式;若是在此基础上的被动含义,就用完成被动式( to have been done).

. He is said to have written a novel about the Long March. He is said to have been taught French when he was a child. 4. 不定式的完成进行式:如果不定式的动作是在谓语所表示的时间之前一直在进行或有可能继续进行的动作,就要用完成进行式. eg: We’re happy to have been working with the experts all the month. 二、不定式的用法: 1. 不定式做主语:不定式做主语一般表示具体的某次动作。而动名词doing 表示习惯的,经常的动作。 1)不定式作主语时,谓语用单数 To do such things is foolish. 2)主系表结构 To see is to believe. 3)it形式主语。当主语较长,谓语较短时,常用it做形式主语,将不定式放到谓语的后面。 常用于下列结构中: (1)It is/was +adj.+(of sb.) to do…(如 good/ kind/ nice/ clever/ foolish/ selfish…) (2)It is +adj.+(for sb.)+to do…(如easy / difficult / hard / / unwise / possible/ necessary…) (3)It is +a/an +名词+ to do...(如a pity/ a shame / a pleasure /one’s duty / an honor …)
