第四頁第五頁，共31頁。4.作結(jié)果狀語表示必然的結(jié)果，通常放在主句后面中間用逗號隔開，有時為了突出結(jié)果，分詞前加thus。Herhusbanddied,leavingherfourchildren.5.作讓步狀語，相當于一個讓步狀語從句Havingtriedmanytimes,hestillcouldn’tsucceed.盡管嘗試了多次，但他仍未成功。Workingveryhard,hedidn’tfeelabittired.盡管拼命地工作，他卻絲毫不感到疲勞。第五頁第六頁，共31頁。6.作條件狀語，表示一種假設情況，相當于一個條件狀語從句。Usingyourhead,youwillfindaway.(=Ifyouuseyourhead,youwillfindaway.)7.作評論性狀語（懸垂結(jié)構(gòu)）作為句子的獨立成分來修飾全句，表明說話者的態(tài)度，觀點等。generallyspeaking一般說來strictlyspeaking嚴格地說franklyspeaking坦率地說第六頁第七頁，共31頁。語態(tài)時態(tài)主動語態(tài)被動語態(tài)一般式完成式(not)doing(not)beingdone(not)havingdone(not)havingbeendone二、現(xiàn)在分詞的各種形式第七頁第八頁，共31頁。動詞,主+動詞(謂語)同時主動doing動詞,主+動詞(謂語)同時被動done分詞前可以加when,after,because,asif,unless,although等表時間,原因,條件,讓步.分詞可以拓展成狀語從句.在其前加not成為否定結(jié)構(gòu)分詞第八頁第九頁，共31頁。動詞,主+動詞(謂語)先后主動havingdone動詞,主+動詞(謂語)先后被動havingbeendone分詞前可以加上when,after,because,if,unless,although等表時間,原因,條件,讓步.分詞可以拓展成狀語從句第九頁第十頁，共31頁。WhenhegiveshisacceptancespeechatGrantParkinChicago,Nov.4,2008,Obama

smiles.GivinghisacceptancespeechatGrantParkinChicago,Nov.4,2008,Obama

smiles第十頁第十一頁，共31頁。分詞(短語)作狀語時,其邏輯主語必須與句子的主語一致。如果不一致,必須用獨立主格結(jié)構(gòu)來表示,也就是在分詞前面加上它的邏輯主語。Findinghercarstolen,shehurriedtoapolicemanforhelp.Thetrainhavinggone,wehadtowaitanotherday.分析:前一例中,-ing形式的邏輯主語為主句的主語。后一例中havinggone的邏輯主語是thetrain。

三、使用-ing形式作狀語需注意的幾個問題第十一頁第十二頁，共31頁。判斷正誤Openingthewindow,abutterflyflewintomystudy.Openingthewindow,Isawabutterflyflyingintomystudy.Standingontopofthetower,thewholecitycomesintoourview.Standingontopofthetower,wecangetaviewofthewholecity.[正][誤][誤][正]第十二頁第十三頁，共31頁。一般來說,-ing形式表示主動、進行;過去分詞表示被動、完成。試比較:

The

enemy

fled

in

a

panic,

leaving

behind

a

lot

of

dead

bodies

and

weapons.

Defeated

and

frightened,

the

enemy

fled

in

a

panic.2.現(xiàn)在分詞與過去分詞作狀語的區(qū)別

分析:前一例中的-ing形式短語在句子中作伴隨狀語,它與其邏輯主語the

enemy之間為主動關系;后一句中的過去分詞defeated和frightened表原因,它與其邏輯主語the

enemy之間為被動關系。第十三頁第十四頁，共31頁。3.分詞短語做狀語時,前面可以加上連詞或介詞,但是分詞短語和句子之間不能用并列連詞(如but,and),因為并列連詞接的是兩個并列成分,而分詞短語只是全句的一個狀語部分,分詞和主句之間可用逗號。Eg.正：Whenseeingfromthetopofthehill,youcanenjoythewholebeautyofthiscity.誤:

Havingbeentoldmanytimes,buthestillcouldn’tunderstandit.第十四頁第十五頁，共31頁。4.-ing分詞的一般式和完成式一般情況下，-ing分詞的一般式的動作表示和后面句子的動作是同時進行的動作；完成式的動作是先于后面句子的動作發(fā)生。如：

Beingastudent,hewasinterestedinbooks.

Nothavingstudiedhislessonsveryhard,hefailedtheexaminations.

第十五頁第十六頁，共31頁。注意：在實際運用中，很多時候-ing的一般式和完成式現(xiàn)在分詞都可以表示先后接連發(fā)生的動作。但如果-ing的動作和主句的謂語動詞之間存在明顯的時間上的先后關系，而且句意強調(diào)完成，為避免引起誤解，必須用完成式表示先發(fā)生的動作。如:Havingbrushedhisteeth,Mr.Browncamedownstairsforbreakfast.布朗先生刷過牙,就下樓來吃早飯。

(此句如寫成:Brushinghisteeth,Mr.Browncamedownstairsforbreakfast.意為邊刷牙,邊下樓)

第十六頁第十七頁，共31頁。Notfearingthefire,thechildtouchedandgotafingerburnt.

Notknowinghowtofindthesubway,Iaskedapolicemanforhelp.5.分詞的否定形式是在其前面加上not.如:第十七頁第十八頁，共31頁。每空填一詞,使該句與所給句子的意思相同。1.Becausehewasill,hedidn’tgotoschool.
