（现在分词做状语）

-ing分词作状语代替状语从句可以表示

Task1

现在分词作状语代替状语从句时间、原因、结果、条件、让步、方式或伴随情况等，注：从句的主语和主句的主语必须一致。即-ing分词作状语时，它的逻辑主语就是整个句子的主语，并表示主动的关系。

一.-ing分词短语作时间状语，代替一个时间状语从句：注意：1：现在分词所表示的动作与主句的动作一般是同时发生，有时可由连词when,while引出。

2：现在分词所表示的动作一发生，主句的动作就立即发生时如：

Whenhereadthebook,henoddedfromtimetotime.

Whenshesawthosepictures,sherememberedherchildhood.

Seeing

thosepictures,sherememberedherchildhood.

Whilereadingthebook,henoddedfromtimetotime.二、-ing分词短语作原因状语，相当于一个原因状语从句。如：

Ashewasill,hecouldn’tcometoschooltoday.

Beingill,hecouldn’tcometoschooltoday.

三、–ing分词短语作结果状语。如：

Hisfatherdied,（thus）

leavinghimalotofmoney.

Shewassoangrythatshethrewthetoyontheground,breakingitintopieces.

四、-ing分词也可作条件状语和让步状语，相当于一个条件状语从句和让步状语从句。Ifyouuseyourhead,youwillfindaway.Usingyourhead,youwillfindaway.Thoughtheyknewallthis,theymademepayforthedamage.Knowingallthis,theymademepayforthedamage.

五、-ing分词作伴随状语

Theystoodthereforhalfanhourwatchingthestarsinthesky.

Followingtheoldman,theyoungpeoplestartedwalkingslowly.

___________by

theoldman,theyoungpeoplestartedwalkingslowly.Followed状语现在分词过去分词

doing与主语为主动关系done与主语为被动关系分词作状语

其逻辑主语必须与句子主语保持一致Hearingthebadnews,

theycouldn’thelpcrying.Whentheyheardthebadnewsdoing与主语为主动关系Givenmoreattention,

thetreescouldhavegrownbetter.Iftheyhadbeengivenmoreattentiondone与主语为被动关系________fromthetopofthebuilding,wesawthehouselikeamatchbox.________fromthetopofthebuilding,thehouselookslikeamatchbox.SeeingSeensee分词短语做状语时，前面可以加上连词，但是分词短语和句子之间不能用并列连词(如but，and)，因为并列连词接的是两个并列成分，而分词短语只是全句的一个状语部分，分词和主句之间可用逗号。注意：例如:

误:Havingbeentoldmanytimes,buthestillcouldn’tunderstandit.

正:Hewastoldmanytimes,buthestillcouldn’tunderstandit.或

Havingbeentoldmanytimes,hestillcouldn’tunderstandit.对比练习1.________manytimes,buthestillcouldn'tunderstandit.2.________manytimes,hestillcouldn'tunderstandit.

现在分词作状语代替状语从句时间、原因、结果、条件、让步、方式或伴随情况等，注：从句的主语和主句的主语必须一致。即-ing分词作状语时，它的逻辑主语就是整个句子的主语，并表示主动的关系。

Task2:现在分词的时态和语态主动形式被动形式一般式完成式doingbeingdonehavingdonehavingbeendone

现在分词的时态和语态-ing分词的一般式和完成式：

Beingastudent,hewasinterestedinbooks.

Havingfinishedhiswork,hewenthome.

-ing分词的一般式的动作表示和主句的动作是同时进行或者在主句的的动作之后发生；完成式的动作是先于主句的动作发生。HavingbeentotheGreatWallmanytimes,hedidn’tgothereyesterday.分词的动作发生在谓语动词的动作之前-ing分词的被动式-ing分词的被动式表示与主句的主语（分词的逻辑主语）的关系是被动关系。根据-ing分词动作发生的时间，被动式有一般被动式(beingdone)和完成被动式(havingbeendone)。如：

（Havingbeencriticized）

bytheteacher,hegaveupsmoking.

1.AShehadeatentoomuchforsupper,hecouldn’tgotosleep.2.Thisbookbecomewellknownallovertheworldafterithadbeentranslatedintomanydifferentlanguages.Havingeatentoomuchforsupper,hecouldn’tgotosleep.Havingbeentranslatedintomanydifferentlanguages,thisbookbecomewellknownallovertheworld.Notknowinghisaddress,Icoulddonothingbutstayathomeandwait.

现在分词的否定形式Notknowinghisphonenumber,wecouldn’tgetintouchwithher.Nothavingreceivedareply,hedecidedtowriteanotherletter.

Task4

现在分词的独立主格结构分词短语做状语,它逻辑上的主语与句子的主语不一致时,它也有自己独立的逻辑主语,这种结构称为:分词独立主格结构独立结构可以表示伴随动作或情况,表示时间、原因、条件等Astheboyledtheway,wehadnotroublefindingthestrangevillage.Iftheweatherpermits,we’llgoforanoutingtomorrow.leadingtheway,wehadnotroublefindingthestrangevillage.permitting,we’llgoforanoutingtomorrow.

Practice:TheboyTheweather有些分词短语可以做独立成分，用来解释整个句子，不受句子主语的限制。常见的分词短语有：generally(frankly,honestly…)speaking,supposing(假设),judgingfrom(从…判断),talkingof（谈到),speakingof（谈到）等。Generallyspeaking,girlsaremorecarefulthanboys.Supposing
