复合句概念简单句是一个句子。复合句则由两个或多个简单句组成。如果简单句之间为并列关系，构成的是并列复合句。如果简单句之间是从属（即主句和从句）关系，则构成主从复合句。不论是并列复合句还是主从复合句，简单句之间要由适当的连词来连接。表达并列关系的连词and(和；那么)notonly...butalsoor(或者；否则)neither...nor...then(那么)either...or...otherwise(否则)but/while(但是；然而)aswellas(既；又)both...and...(……既又)not...but...(……不是而是)1.Holdon,youreffortswillpayoffoneday.2.Don'tloseyourpatience,yourchanceswillslipaway(溜走).3.Momtriedeverypossiblemeans,shestillfailedeventurally.4.therivershavebeenpolluted,butalsothelocalGDPisdecling.5.Jackwasquitecheerfulatthenew,hissisterseemedindifferent.and/thenor/otherwisebutNotonlywhile主从复合句是由从句和主句构成的。从句充当主句的句子成分，由连词和主句连接，连词如：that,who,whom,whose,which,what,when,where,why,whether,if,unless,as,while,because,so,therefore,thus,though,nowthat...等根据从句在主句中充当的成分，从句就相应的被称作主语从句宾语从句表语从句同位语从句定语从句状语从句名词性从句形容词性从句时间状语从句地点状语从句原因状语从句让步状语从句Ireachedthegatethatopenedontothelake分析：Turnofftheswitchwhenanythinggoeswrongwiththemachine.分析：Herearethechairs.Tellmewhichareworthbuying.分析：从句都有如下共性：1.从句本身结构完整，即有主语、谓语、宾语、表语、状语、宾语补足语等成分。名词性从句和状语从句的句子成分比较明显；定语从句中，有时先行词充当从句的主语、宾语或是状语，句子缺了此成分而显得不完整。Ourteachertoldusthatthefemale主语astronautwouldgivelessonsinthespace.谓语宾语地点状语名词性从句IwasadvisedtorefertoadictionarywhenIdidn'tknowaword'smeaning.Someonetookawayherhandbagwhichlookednewandfashionable.时间状语从句主语谓语宾语谓语表语定语从句先行词handbag作定语从句主语Shetoldmeherfeelingthatshewashappy.(同位语从句、名词性从句)I'llneverforgetthedayswhenwespenthappilytogether.(定语从句)Theyknewnothingaboutthetreasureexceptwhenitwasburied.(状语从句)2.从句都用陈述语序但当连接代词(who,what,which,whose等)作从句的主语时，从句依然使用疑问语序Pleasetellmewhowasthepresident.Iwannatoknowwhatisthematter?Shelostthebookwhosecoverisgreen.3.一个从句只能用一个连词连接，不能同时用两个或多个连接词。改错：1.DetectiveCuffdidn'tdoubtthatwhetherGodfreystolethediamond.2.TheyremindedmesothatwhyIwouldn'tforgetaboutthemeeting.3.MyteachertoldmeawaythathowIcouldworkouttheproblem.观察下列句子Thelittleboyaskedaquestionhowwhenitwasheated,icewouldchange.Thelittleboyaskedaquestionhowicewouldchangewhenitwasheated.这是两个复合句，从句中又使用了从句。才有两个连词。4.复合句之间要用连词连接，不能用逗号“,”连接。Peterhandedinhishomeworklate,thismadehisteacherangry.Jacksaidsomethingimpropertoher,heapologizedforthat.5.如简单句后只有逗号与后文连接，这就暗示逗号后不可能是另一个简单句，很可能是充当状语成分的形容词、分词、独立主格结构等。(see)fromthehilltop,theschoolappearssmall.LittleKatewassittingatthewindow,(read)abook.While(walk)thedog,youlostit.Wether(permit),wearegoingtovisitourteacher.whichsoSeenreadingwalkingpermitting1.Theyrushedovertohelpthemancarhadbrokendown.2.ThefarmwevisitedyesterdayislocatedinthesuburbofBeijing.3.InevermetJuliaagainafterthat,wasapity.4.it'sraining,theyarestillworkinginthefield.5.Don'tgetoffthebusithasstopped.6.Everybodyknowsmoneydoesn'tgrowontrees.7.thepolicewanttoknowiswhenyouenteredtheroom.8.(finish)theirwork,theyshoppedataconvenientstore.whosethat...
