2018高考英语非谓语动词专项讲解练习第五章非谓语动词【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 country in the world.(原因)Generally speaking,if taken according to the directions,the drug has no side effect.(条件)He glanced at her,nothing that though she was tiny,she seemed very well.(结果)Having been told many times,he still repeated the same mistake.(让步)The teacher came into the lab,followed by some students.(伴随)四.独立成分作状语有些分词或不定式短语作状语,其形式的选择不受上下文的影响,称作独立成分.常见的有:generallyspeaking一般来说;frankly speaking坦白地说;judging from/by...根据....来判断;considering.../taking....into consideration考虑到.....;to tell you the truth说实话;compared to/with与....相比.Judging from his accent,he is from Hong Kong.Considering your health,you'd better have a rest.To tell you the truth,I am a little tired.五.独立主格结构非谓语动词作状语时,它的逻辑主语应和句子主语保持一致.但有时非谓语动词带有自己的逻辑主语,在句子中作状语,我们称之为独立主格结构.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独立主格结构中作逻辑主语的名词或代词与后面的分词或不定式是逻辑上的主动或被动关系.③独立主格结构一般有逗号与句子分开.独立主格结构的构成:①名词/代词+分词②名词/代词+不定式③with/without+名词/代词+分词/不定式The test finished(=When the test was finished),we began our holiday.The president assassinated(=Because the president was assassinated),the whole country was in deep sorrow.

Games.③有些名词的同根词常跟不定式,因而它们也常跟不定式作定语,常见的有:promise,plan,attempt,offer,decision,refusal,failure,ability,chance,warning,anxiety,eagerness,willingne ss,readiness等.I don't trust his promise to come for a
