where从句说明动作发生的地点，地点状语从句where从句修饰theplace，定语从句13.3.原因状语从句because/as/since（=nowthat）/forbecause语气最强，引导的从句可放前面也可放后面，回答why，可引导表语从句。as/since不能回答why。Hecouldn’thaveseenme,becauseIwasnotthere.since相当于nowthat，语气较弱，

as语气最弱,as和since均表示双方都知道的原因，通常都放在句首。Sinceeverybodyhascome,wecansetoff.Asheishonestandmodest,allhisfriendslikehim.for是并列连词，只能放在句中，for分句不是前面分句发生的直接原因，只提供一种判断的依据或对前面分句加以解释。Itrainedlastnight,forthegroundiswetnow.14.4.条件状语从句if,unless,aslongas,incase,onconditionthatetc.15.if“如果”，表示正面的条件Ifyouworkharder,youwillsucceed.Workharder,andyouwillsucceed.Workharder,oryouwon’tsucceed.Workingharder,youwillsucceed.16.unless表示反面的条件，“除非，如果不”Wecan’twritetoMaryunlessshetellsusheraddress.Wecan’twritetoMaryifshedoesn’ttellusheraddress.17.aslongas/solongas(只要)1)IwillnevergiveuplearningaslongasIlive.2)Youmayborrowthebookaslongasyoukeepitclean.18.incase假使,如果Sendusamessageincaseyouhaveanydifficulty.19.onconditionthat…条件是…Hesaidthathewouldcometothemeetingonconditionthatnooneaskedhimtospeak.20.5.目的状语从句sothat,inorderthat,incase,forfearthatetc.21.Let’stakethefrontseatssothatwecanseemoreclearly.sothat“为了”，要放在主句之后，soasto…同从句中要使用情态动词，如：can,could,may,might等22.inorderthat“为了”，放在主句前和后均可。inorderto…同Schoolwasclosedearlyinorderthatthechildrenmightgohomeaheadofthestorm.23.forfearthat唯恐；以免Theinstructoremphasizedtheissuethreetimesforfearthatthestudentsdidnotpayenoughattentiontotheproblem.24.incase以免；万一Bettertakemoreclothesincasetheweatheriscold.25.6.结果状语从句sothat,so…that…，such…that…Wetookthefrontseatssothatwesawmoreclearly.ItissogoodastorythatI’llneverforgetit.ItissuchagoodstorythatI’llneverforgetit.such+名词+thatclauseso+adj./adv.+thatclauseso+many/few+复数名词+thatclausemuch/little+不可数名词26.as按照;asif/asthough似乎；好像WheninRomedoastheRomansdo.YoumusttrytodoasIdid.I’lldoasIamtoldto.

如果主从句主语一致，从句谓语动词为be或含有be的某种形式,就可以省略从句中的“主语+be”部分；另外如果从句主语是it，谓语为be或含有be的某种形式，就可以把从句中的it+be部分省去。此省略现象常出现在时间、条件、让步、比较、方式、原因等状语从句中。Unless（Iam）invited,Iwon’tattendtheirwedding.
