三、高考热点问题：1．状语从句的时态在时间、条件和让步状语从句中常常用一般现在时代替一般将来时，一般过去时代替过去将来时，现在完成时代替将来完成时。Youwon'tunderstandthestorycompletelyuntilyouhavefinishedreadingit.Hewillpayavisittoyouassoonashegetshere.HesaidwheneverIwasintroubleIcouldturntohim.2．状语从句的省略当状语从句的主语和主句主语保持一致，且从句谓语动词中含有be动词，可以将状语从句中的主语和be动词一起省略。Whenintrouble，askthechairmanhimself.Althoughfrightened，hemanagedtorunaway.Whilecrossingtheroad，youshouldwatchout.另在ifitispossible，whenitisnecessary等类似结构中，itis常可省。Holdyourheadhighifnecessary.3．状语从句与名词性从句的区别wh－开头的词既可引导状语从句，相当于nomatterwh－；也可引导名词性从句，相当于anythingthat/anyonewho；分辨它们的窍门在于wh－引导名词性从句时，去掉从句，主句成分意思不完整，而wh－引导状语从句时，去掉从句，主句意思成分完整清晰。Whoeveryouare(＝Nomatterwhoyouare)，youmustobeytheregulations.(状语从句)Whoeverarrivesfirst(＝Nomatterwhoarrivesfirst)willwinthegoldmedal.(主语从句)4．状语从句与定语从句的区别(1)where与when引导的状语从句容易与它们引导的定语从句相混淆。when与where引导定语从句时，有先行词，可被介词＋which替代；它们引导状语从句时，主句中没有相应的先行词，也不能被介词＋which替代。Thegraduatesshouldgowheretheyareneededmost.(状语从句)Thegraduatesshouldgototheplacewhere/inwhichtheyareneeded.(定语从句)Iwasthehappiestwhenmyparentsweretogetherwithme.(状语从句)Iwasthehappiestduringthetimewhen/atwhichmyparentsweretogetherwithme.(定语从句)(2)so/such...that引导的结果状语从句和so/such...as引导的定语从句so/such...that引导结果状语从句时，that没有任何意义，也不在从句中充当任何成分；而so/such...as引导定语从句时，as为关系代词，在从句中必须充当句子成分，代替先行词。Thequestionissodifficultthatnoonecananswerit.(状语从句)Itissodifficultaquestionasnoonecananswer.(定语从句)Heissuchagoodspeakerthatweallbelievehim.(状语从句)Heissuchagoodspeakerasweallbelieve.(定语从句)5．状语从句与强调句型的区别Itwasthefactorywheretheaccidenthappened.(地点状语从句，it指代那家工厂)Itwasinthefactorythattheaccidenthappened.(强调句型，it无具体意义，仅构成强调句型)ItwasmidnightwhenhearrivedChangsha.(时间状语从句，it指时间)ItwasatmidnightthathearrivedChangsha.(强调句型，it无具体意义，仅构成强调句型)从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。()1.Hemadeamistake，butthenhecorrectedthesituation________itgotworse.A．untilB．unlessC．beforeD．as1．C。考查状语从句引导词的选用。句意：他犯了错，但及时采取了补救措施，没让事情变得更糟。()2.Theconsequencesofouractionsareunbelievablycomplicatedanddiverse________predictingthefutureisaverydifficultbusinessindeed.A．becauseB．evenifC．inorderthatD．sothat2．D。sothat引导结果状语从句，根据句意应该选sothat。()3.________makeshisparentsproudis________henevergivesup，________difficultthesituationis.A．Whatever；不填；howeverB．What；不填；howC．What；that；howeverD．Whatever；that；how3．C。第一空what引导主语从句，第二空that引导表语从句，第三空however引导让步状语从句，相当于nomatterhow。()4.Whatwehavebeendoingmaynotdousmuchgood，but________itwillbenefitusorothers，we'lljuststickitout.A．nomatterB．howeverC．whetherD．although4．C。whether与or连用，引导让步状语从句，相当于nomatterwhether。()5.It'squiteatime________theplayergotinjured，butitwon'tbelong________hereturnstothecourt.A．since；beforeB．after；whenC．before；sinceD．that；when5．A。itis代替ithasbeen，故第一空使用since；第二空用before表示“要不了多久就……”。()6.Weshouldbeabletodothejobforyouquickly，________yougiveusallthenecessaryinformation.A．incaseB．providedthatC．orelseD．asif6．B。providedthat引导状语从句，意为“只要”，还可表示为“providingthat”。()7.Itisnotnecessarytoexplainthetruth________thereareair，waterandsunlight，therearelivingthings.A．inwhereverB．thatwhereverC．whichD．that7．B。that引导同位语从句，同位语从句中又包含一个wherever引导的让步状语从句。()8.Theinfluenceofautomobileextendsthroughouttheeconomy________thecarissoimportanttoAmericanpeople.A．thatB．asC．soD．though8．B。句意：汽车的影响延伸到整个美国经济界，因为汽车对于美国人来说太重要了。()9.Thegovernmentshouldprotecttheoldvaluablebuildings________theyarenotinharmonywiththemodernonesnearby.A．eventhoughB．asifC．sothatD．nowthat9．A。句意：尽管这些古老的建筑和附近的现代化的东西不协调，但是政府也要保护它们。()10.—Howthesestudentswishtheycouldstudy________therearefewerexams!—Icanunderstandtheirpressure.A．whereB．inwhichC．theplacewhereD．inwhere10．A。where引导地点状语从句。
