Chapter5MemoryLanguage一.教学内容：Chapter6MemoryLanguageandwriting（一）“if”与“unless”引导的条件状语从句和状语从句知识归纳（二）课后书面表达讲解二.知识总结与归纳：“if”与“unless”引导的条件状语从句条件句，放在前，逗号要放句中间。条件句表可能，主句多用将来时；条件句表事实，主句常用现在时。在if引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如：Wecanwalkthereifwecan’tfindabus.Ifitrainstomorrow,wewillnotgotothezoo.Whatwillyoudoifyoufindapandaindanger?如果if条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如：Ifbearsareindanger，theyattackpeople.要点：表示状语从句由连词if，unless（＝ifnot）引导。1.Ifitdoesn’traintomorrow,wewillgohiking.如果明天不下雨，我们就去远足。2.Youwillgetgoodgradesifyoustudyhard.如果你努力学习，就会取得好成绩。3.Iwillgotothepartyunlesshegoestheretoo.我不会去参加聚会的，除非他也去。（如果他不去，我也不去。）4.Youwillbelateunlessyouleaveimmediately.如果你不马上走，你将会迟到的。（＝Ifyoudon’tleaveimmediately,youwillbelate.）难点提示：用条件状语从句时要注意时态的正确使用，当主句是将来时的时候，从句要用一般现在时。1.Hewillnotleaveifitisn’tfinetomorrow.（一般将来时，一般现在时）2.Theyaregoingtohaveapicnicifitdoesn’trainnextweek.（一般将来时，一般现在时）[状语从句知识归纳]状语从句（AdverbialClause）状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词（从属连词）引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。状语从句的种类用来修饰谓语动词、其它动词、定语、状语或整个句子的从句叫做状语从句。状语从句可分为：1.时间状语从句；（adverbialclauseoftime）2.地点状语从句；（adverbialclauseofplace）3.原因状语从句；（adverbialclauseofcause）4.条件状语从句；（adverbialclauseofcondition）5.目的状语从句；（adverbialclauseofpurpose）6.让步状语从句；（adverbialclauseofconcession）7.比较状语从句；（adverbialclauseofcomparison）8.方式状语从句；（adverbialclauseofmanner）1.时间状语从句（adverbialclauseoftime）由when，while，as引导的时间状语从句。例如：Whenyouthinkyouknownothing,thenyoubegintoknowsomething.Strikewhiletheironishot.WillyouwatchmyclotheswhileIhaveaswim?Youcanfeeltheairmovingasyourhandpushesthroughit.Ourheadmasterlaughedasshespoke.Itwillbefourdaysbeforetheycomeback.Einsteinalmostknockedmedownbeforehesawme.MyfatherhadleftforCanadajustbeforetheletterarrived.Theyhadnotbeenmarriedfourmonthsbeforetheyweredivorced.Afteryouthinkitover,pleaseletmeknowwhatyoudecide.Afterwehadfinishedthework,wewenthome.Ididn’tgotobeduntil（till）myfathercameback.ItwasnotuntilthemeetingwasoverthathebegantoteachmeEnglish.Iworkeduntilhecameback.Ididn’tworkuntilhecameback.PleasewaituntilIarrived.IhavebeeninBeijingsinceyouleft.AssoonasIreachCanada,Iwillringyouup.2.地点状语从句；（adverbialclauseofplace）Wherethereisnorain,farmingisdifficultorimpossible.Theyweregoodpersons.Wheretheywent,theretheywerewarmlywelcomed.Youshouldhaveputthebookwhereyoufoundit.Wherethereisawill,thereisaway.Itwillbemixedschoolwherenotallthechildrenaredisabled.Whereveryougo,Igotoo.Whereverthereissmoke,thereisfire.Whileshewaswonderingwheretogo,shemetapoliceman.3.原因状语从句；（adverbialclauseofcause）Ididn’tgotoschoolyesterdaybecauseIw...
