选修6句型结构总复习1.while连接的并列句ThestyleofWesternarthaschangedmanytimes,whileChinesearthaschangedlessoften.(P1)while常常用作从属连词,表示“当……的时候”,它也可以连接两个并列句,意为“然而”。eg:IthoughtIheardhimcomeinwhilewewerehavingdinner.while,but,however的区别:(1)while虽然表示转折,但是它侧重于两者之间的对比。eg:ShethoughtIwastalkingaboutherdaughter,whileinfact,Iwastalkingaboutmydaughter.while还可引导让步状语从句,相当于although。eg:WhileIunderstandwhatyousay,Ican’tagreewithyou.(2)but要放在句中,不能用逗号同后面的句子隔开。eg:Hedoesn’tlikemusicbuthiswifedoes.(本句只能用but)(3)however在表示这个意义时是副词,所以用逗号同后面的句子隔开,而且位置也比较灵活,可以置于句首、句中或句末。eg:Thisisonepossiblesolutiontotheproblem.However,thereareothers.2.if引导的虚拟条件句Iftherulesofperspectivehadnotbeendiscovered,peoplewouldnothavebeenabletopaintsuchrealisticpictures.(P2)该句为虚拟语气在条件句中的应用。虚拟语气在条件句中的应用可以有以下三种情况:(1)与过去事实相反:从句用haddone…,主句用would/could/should/might+do。eg:Thehousewouldnothavebeenburntifyouhadbeenmorecareful.(2)与现在事实相反:从句动词用过去时,be动词用were(IfIwereyou…),主句用would/could/should/might+do。eg:Ifmyunclewerehere,hewouldhelpusdealwiththeproblem.(3)与将来事实相反:从句用eq\o\ac(○,1)过去时,be动词用were;eq\o\ac(○,2)should+do;eq\o\ac(○,3)wereto+do,主句用would/could/should/might+do。eg:Ifyouattendedtomorrow’smeeting,itwouldbemoreinteresting.Ifyouweretosucceed,everythingwouldbeallright.Ifitshouldraintomorrow,weshouldhavetoputoffthetravelplan.通常情况下,在非真实条件句中,主句和从句的谓语动词所指时间是一致的,但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式,也就是混合条件句。eg:Ifyouhadlistenedtomecarefullyyesterday,youwouldbeabletoanswermyquestionsnow.(从句与过去事实相反,主句与现在事实相反,因为有现在时间状语now。)3.see+宾语+宾补Isawahousebowtoasquire,…(P10)see后面的复合结构很复杂,在这个句子中是接不带to的动词不定式。在此种情况下,往往表示将来的动作或是过去完成的动作,而且这个动作往往是瞬间发生的。eg:Isawathiefslipintomyneighbour’shouse.(1)在“see+宾语+过去分词”这个结构中,宾语与后面的过去分词存在逻辑上的动宾关系。eg:Justnow,Isawanoldmanknockeddownbyaspeedingcar.(2)“see+宾语+动词–ing形式”这个结构表示看到某动作正在进行。eg:Themissingchildwaslastseenplayingbytheriver.(3)“see+宾语+beingdone”表示看到某事正在被做。eg:WhenIwaspassingbyBeijing,Isawmanygymsandstadiumsbeingbuiltforthe2008OlympicGames.4.as+adj.+a(n)+n.+as…IdohopesobecauseIwantyoutoliveaslongandhealthyalifea
