itoesshouldbecompletelyexterminatedwherefound.●Retireesingoodhealthshouldbeinvitedtoreturntoworkwhereverneeded.（3）由if,unless引导，表示“条件”，如：●Ifkeptfortoolong,somemedicineswilllosetheireffectiveness.●Wehavemadeapointofnotattackingunlessattacked.（4）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,hisheadinclinedtooneside4.Studyingthepastparticipleastheattribute过去分词作定语，在语态上，表被动；在时间上，表示动作已经发生或完成，与它所修饰的名词有逻辑上的动宾关系。过去分词作定语时，所修饰的名词在逻辑上相当于被动句中的主语，过去分词相当于谓语。过去分词作定语表示动作在谓语动作之前发生，已经完成并具有被动意义。有时也不表示时间性。作定语的过去分词一般由及物动词变来，因为只有及物动词才有被动意义。例如：Heisateacherlovedbyhisstudents.他是个很受学生爱戴的老师。-9-必修5教案\n也有用不及物动词的过去分词作定语的情况，一般作前置定语，它不表示被动意义，只表示主动意义，强调动作完成。不能像及物动词的过去分词那样放在名词后面作定语。例如：fallenleaves落叶,retiredworkers退休工人,therisensun升起的太阳注意下面过去分词作定语的几种情况：A.单个的过去分词作定语一般放在被修饰的名词之前。例如：Weneededmuchmorequalifiedworkers.我们需要更多的合格的工人。Myfriendisareturnedstudent.我的朋友是个归国的留学生。单个分词也可以作后置定语，用以强调动作。例如：Theydecidedtochangethematerialused.他们决定更换使用的材料。B.过去分词短语作定语要放在被修饰的名词后面，作后置定语，其作用相当于一个定语从句。例如：Thestudentdressedinwhiteismydaughter.(=Thestudentwhoisdressedinwhiteismydaughter.)C.如果被修饰的词是由every/some/any/no+thing/body/one所构成的复合代词或指示代词those等时，即使一个单一的分词作形容词用，也要放在被修饰词的后面。例如：Isthereanythingunsolved?ThereisnotingchangedheresinceIleftthistown.D.单个过去分词前加一名词或副词，常用连字符将它们连接起来构成一个复合形容词，放在其修饰的名词前，作前置定语。分词前加的名词表示分词的动作或行为主体，所加的副词表示方式、时间、程度、性质等意义。例如：Thisisastate-ownedfactory.Thisisourschool-runfactory.E.作前置定语的某些动词的过去分词的形式与作谓语或表语的过去分词的形式往往不一样。例如： 原形用作定语的过去分词用作表语或谓语的过去分词 drinkdrunken drunk lightlightedlit lit melt melten melted sink Sunken SunkWelitthecandleandthecandlelituptheroom.我们点着蜡烛，蜡烛照亮房间。Thereisalightedcandleonthetable.桌上有一支点着的蜡烛。5．PracticepastparticipleusedasadverbialandattributeCompletethefollowingsentenceswiththewordsgiven,usingtheirproperforms.1,Ilikereadingthenovels______(write)byhim2.Thegirl________(write)aletterismycousin3.ThereissomethingwrongwithmybikeandIhavetogetit__________(repair).4.Hespokeloudlyinordertomakehimself____(hear)-9-必修5教案
