現(xiàn)在分詞作賓語補足語和狀語

用法歸納

現(xiàn)在分詞作賓補，表示賓語與作賓補的動詞之間是主動關(guān)系。1.動詞的賓語補足語1)位于感官動詞后：如see,hear,feel,smell,watch,find,listento,lookat,notice,observe等。①Wesawthebiologyteacherdoingtheexperiment.Inoticedhimbeingtakenawaybyapoliceman.2)位于其他動詞后：如set,keep,have,get,leave,catch等。②Inordertokeepwarm,wekeptthefireburning.Don’tleaveherwaitingoutsideinthecoldwind.注意：現(xiàn)在分詞作賓補，常放在賓語后面,表示一個_________________的動作,強調(diào)一個過程或一種狀態(tài)。而用不帶to的不定式，即動詞原形作賓補，則表示動作的全過程。正在進行的主動性2.with復(fù)合結(jié)構(gòu)

在with復(fù)合結(jié)構(gòu)中，如果賓語發(fā)出動作，且表示動作持續(xù)或進行，則用現(xiàn)在分詞作賓補。v-ingform對賓語起補充說明作用。注意：在with復(fù)合結(jié)構(gòu)中，動詞不定式作賓補雖然也表示賓語發(fā)出動作，但是表示動作將要發(fā)生。③Hewassotiredandsoonfellasleepwiththelightstillburning.

用法歸納1.現(xiàn)在分詞的一般式與完成式現(xiàn)在分詞的一般式(doing)作狀語表示動作與謂語動詞的動作同時發(fā)生；現(xiàn)在分詞的完成式(havingdone)作狀語表示動作發(fā)生在謂語動作之前。2.現(xiàn)在分詞的主動式(doing/havingdone)作狀語時，表示邏輯主語和其之間是主動關(guān)系；現(xiàn)在分詞的被動式(beingdone/havingbeendone)作狀語時，表示邏輯主語和其之間是被動關(guān)系。注意：現(xiàn)在分詞的邏輯主語是句子的主語。主動形式被動形式一般式完成式doing

beingdonehavingdonehavingbeendone3.現(xiàn)在分詞作狀語的功能現(xiàn)在分詞作狀語可以表示時間、原因、條件、讓步、結(jié)果、方式或伴隨等，相當于狀語從句。v-ing形式作狀語，其邏輯主語是句子的主語，且和主語構(gòu)成主動關(guān)系。例：1.Notknowinghisaddress,Icoulddonothingbutstayathomeandwait.

（主動意義，v-ing的動作和謂語的動作幾乎同時發(fā)生。）2.Nothavingstudiedhislessonsveryhard,hefailedtheexaminations.(主動意義，v-ing的動作發(fā)生在謂語的動作之前。）（1）時間狀語

表示時間，位于句子前半部分，可與when，while引導(dǎo)的時間狀語從句相互轉(zhuǎn)換；有時分詞前加when或while以示強調(diào)。例：Hearingthenews,hegotfrightened.?=Whenheheardthenews,hegotfrightened.=BecauseIdon’tknowheraddress,Ican’twritetoher.

（2）原因狀語

表示原因，位于句子前半部分，可與as,since,because引導(dǎo)的原因狀語從句相互轉(zhuǎn)換。例：Notknowinghisaddress,Ican’tsendthisbooktohim.?（3）條件狀語

表示條件，位于句子前半部分，可與if,unless等引導(dǎo)的條件狀語從句相互轉(zhuǎn)換。例：Takingthepaththatleadsoutofthetown,youwillcometoalake.?=Ifyoutakethepaththatleadsoutofthetown,youwillcometoalake.（4）讓步狀語

作讓步狀語，相當于讓步狀語從句，有時現(xiàn)在分詞（短語）前可帶有連詞although,evenif,eventhough等。例：Knowingallthis,theymademepayforthedamage.?=Althoughtheyknewallthis,theymademepayforthedamage.（5）結(jié)果狀語

現(xiàn)在分詞作結(jié)果狀語時表示必然的結(jié)果，通常放在句末。有時為了突出結(jié)果，現(xiàn)在分詞前可加thus，相當于so或sothat引導(dǎo)的結(jié)果狀語從句，有時相當于一個并列句。注意：不定式作結(jié)果狀語時，常與only,never連用，表示一種出乎意料的結(jié)果。例：Shewassoangrythatshethrewthetoyontheground,breakingitintopieces.=Shewassoangrythatshethrewthetoyontheground,andbrokeitintopieces.（6）方式或伴隨狀語

動詞-ing作方式或伴隨狀語時，謂語動詞表示動作發(fā)生的方式、背景或情況。此時分詞的動作和謂語動詞的動作同時發(fā)生?，F(xiàn)在分詞或分詞短語作伴隨狀語時可以轉(zhuǎn)換成并列成分。例：Theystoodthereforhalfanhourwatchingthestarsinthesky.=Theystoodthereforhalfanhourandwatchedthestarsinthesky.（7）評論性狀語

有些現(xiàn)在分詞（短語）沒有邏輯主語而獨立存在，往往位于句首用來修飾全句，表明說話者的態(tài)度、觀點等。如：judgingfrom/by由……判斷considering...考慮到……supposing/providing/assuming...如果/假設(shè)……generally/strictly/honestly/roughly/franklyspeaking一般/嚴格/誠實/大致/坦率說來（8）現(xiàn)在分詞構(gòu)成的獨立主格結(jié)構(gòu)

有時現(xiàn)在分詞可以有自己獨立的邏輯主語，這種結(jié)構(gòu)稱為獨立主格結(jié)構(gòu)。獨立主格結(jié)構(gòu)通常用來表示伴隨的動作或情況，有時還可以表示時間、原因、條件或解釋整個句子。例：Hishairbecamegreywiththeyearspassing.隨著時間的推移，他的頭發(fā)變花白了Exercises1Readthesentencesbelowanddiscussthefunctionandmeaningofeach-ingform.Thenfindmoreexamplesfromtheunit.1...herbrothercomplained,thinkingofthehightuitiontees.2Thinkingofallthepeoplestillinneedofhelp,DrLinopenedaprivateclinic3ThenewPeople'sRepublicofChinasawDrLinQiaozhiplayingakeyrole.adverbialadverbialobject
