theexamination.在动词see,hear,feel,watch,notice,perceive,observe,listento,lookat后既可用现在分词作补语,也可用不定式作补语。用现在分词表示动作正在进行,用不定式表示的动作的全过程已经完成。例如:IsawMr.Whitegetoffabus.IsawMr.Whitelookingintoashopwindow.—Doyouhearsomeoneknockingatthedoor?—Yes,Idid.Iheardhimknockthreetimes.5)分词作表语分词作表语通常看作形容词来用。现在分词表示主语的性质,而且主语多为物;过去分词表示主语的感受或状态,主语多为人。例如:Thefilm“PearlHarbor”isreallyexciting.Iamexcitedaboutit.Hisresponsetothequestionwasquitedisappointing.Ifeltdisappointedathisresponse.具副词功能的过去分词短语和现在分词及短语一样,过去分词（pastparticiples）或过去分词短语（pastparticipialphrases）也可以充当副词,修饰谓语动词。过去分词短语可以表达下列四种意思:(一)方法或活动方式,如:Hewalkedupanddown,lostinthought.Isatbeforethedeskuntilaftermid-night,absorbedinwriting.Surroundedbyahostoffans,thefilmstarlefttheairportexcitedly.(二)原因,如:Greatlydisappointed,somestaffdecidedtoleavetheplace.Takenbysurprise,theenemysurrendered.(三)时间,如:Bornandbredinaturbulentage,theoldergenerationofpeopleexperiencedallsortsofhardships.Throwntothefloor,theboyregainedhisfootingafewminuteslater.(四)条件,如:Givenmoretime,theslowlearnerswouldhavedonebetter.Criticizedbysomeoneelse,Tonywouldnothaveflareduplikethat.除了直接修饰动词之外,过去分词或短语也可以和连词合组成短语,表示下列四种意思:⒈由when,whenever,while,until等连词引导,表示“时间”,如:Whenaskedabouthispreviousjob,Billsaidhehadbeenamotormechanic.Susanseldomspeaksinclassuntilspokento.⒉由where,wherever连词引导,表示“地点”,如:Mosquitoesshouldbecompletelyexterminatedwherefound.9,Retireesingoodhealthshouldbeinvitedtoreturntoworkwhereverneeded.⒊由if,unless引导,表示“条件”,如:Ifkeptfortoolong,somemedicineswilllosetheireffectiveness.Wehavemadeapointofnotattackingunlessattacked.⒋由though,although,eventhough连词引导,表示“让步”,如:Thoughwarnedofthedanger,theystillwentmountaineering.Eventhoughdefeatedforasecondtime,ourteamdidnotgiveuphopefortheultimatevictory.此外,过去分词短语还可以和介词“with”或“without”连用,具副词作用。如:Withthewaterpipechoked,therewasn’tanymorewaterforuse.Withoutanythingleftinthekitchen,theWangsdecidedtoeatout.最后,过去分词短语,在适当情况下,可以有自己的主语而变成独立结构（theabsoluteconstruction）,如:Theoldmanlistened,hisheadinclinedtooneside.9
