    虚拟语气13.

    Asif(though)+主语+did/haddone…表示过去的情况用过去完成时,表示现在和将来的情况用过去时

    Ourheadteachertreatsusasifwewereherownchildren,soallthestudentsinourclassthinkhighlyofher.

    AlantalkedaboutRomeasifhehadbeenthere.

    Alltoooften,peopletreatAIDSpatientsasiftheywerebadordangerous.

    75.关系代词as,which的区别

    (1)。当定语从句是否定句或表示否定时只能用which.

    Hecamehereverylate,whichwasunexpected.

    (2)。当as在从句中作主语是,后面常接动词的被动语态。如:beknown,besaid,bereported,beannounced.如从句的行为动词是主动语态,一般用which作主语。

    Shehasbeenabsentagain,asisexpected.

    Tomhasmaderapidprogress,whichmakesmeveryhappy.

    (3)。As常用在as(it)seemslikely,as(it)oftenhappens,as(it)wasprintedout,as(it)wassaidearlier,asIremember(it),asIunderstand(it),as(it)appears.等结构

    Jackhaswonthefirstprize,asitoftenhappens.

    ShehasreadwidelyinRomanticliterature,asitappearsfromheressay.

    (4)。As仍然保持作连词时常有的某种含义。

    Davidistall,asaremybrothers.

    Heopposedtheidea,ascouldbeexpected.

    (5)。当非限定性定语从句是一个复合结构时,只能用which

    Bettyalwaystellalie,whichherparentsfindstrange.

    76.关系副词where的用法;高考对where的考察驱于复杂,从先行词为明显的地点,转为地点模糊化。当先行词表示某人/物的situation,或某事物所发展的stage,或表示某事物的某方面时都可用where.

    Eg.Theaccidenthadreachedapointwhereboththeirparentsaretobecalledin.

    Wherewillallthistroublelead?

    Thatiswhereyouaremistaken.

    Youaresayingthateveryoneshouldbeequal,andthisiswhereIdisagree.

    Icanthinkofmanycases,wherestudentsobviouslyknewalotofEnglishwordsandexpressionsbutcouldn‘twriteagoodessay
