1初中英语语法总结——连词连词是一种虚词,它不能独立担任句子成分而只起连接词与词,短语与短语以及句与句的作用。连词主要可分为两类:并列连词和从属连词。并列连词并列连词用来连接平行的词、词组和分句。第一类表示并列关系的连词1)and和判断改错:(错)Theysatdownandtalkaboutsomething.(错)Theystartedtodanceandsang.(错)Isawtwomensittingbehindandwhisperthere.(对)Theysatdownandtalkedaboutsomething.(对)Theystartedtodanceandsing.(对)Isawtwomensittingbehindandwhisperingthere.解析:第一句:and连接两个并列的谓语,所以talk应改为talked。第二句:and连接两个并列的动词不定式,第二个不定式往往省略to,因此sang应改为sing。第三句:and连接感观动词saw后面的用作的宾补的两个并列分词结构,因此whisper应改为whispering。注意:1.and还可以和祈使句或名词词组连用表示条件。(or也有此用法)Makeupyourmind,andyou'llgetthechance.=Ifyoumakeupyourmind,you'llgetthechance.Onemoreeffort,andyou'llsucceed.=Ifyoumakeonemoreeffort,you'llsucceed2,AandB当表示整体或者指同一人时谓语动词用单数,当and连接的单数名词前分别有each,every,many等词修饰时,谓语也用单数。breadandbutteraknifeandforkThemotherandteacherisverystrictwithherson.Noteacherandnostudentisallowedtosmokeinclass.3.and连接的是两个相同意思的词,表示“渐渐”,或加强语气Readitagainandagain2)both…and两者都Sheplays(both)thepianoandtheguitar.3)neither…nor意思为"既不……也不……"谓语动词采用就近原则,与nor后的词保持一致。Neitheryounorheistoblame.4)notonly…but(also)不但······而且······2Sheplaysnotonlythepiano,but(also)theguitar.注意:notonly…butalso关联两个分句时,一个分句因有否定词not而必须倒装。Notonlydoeshelikereadingstories,butalsohecanevenwritesome.5)aswellas以及,也,与···同样Theteacher,aswellasthestudents,isinterestedintheactivity.比较and和or1)并列结构中,or通常用于否定句,and用于肯定句。2)但有时and也可用于否定句。请注意其不同特点:Thereisnoairorwaterinthemoon.Thereisnoairandnowateronthemoon.在否定中并列结构用or连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。典型例题---Idon'tlikechicken___fish.---Idon'tlikechicken,___Ilikefishverymuch.A.and;andB.and;butC.or;butD.or;and答案C。否定句中表并列用or,but表转折。判断改错:(错)Wewilldiewithoutairandwater.(错)Wecan'tlivewithoutairorwater.(对)Wewilldiewithoutairorwater.(对)Wecan'tlivewithoutairandwater.第二类表示选择关系的连词1)or意思为"或则"。Whichdoyouprefer,tea,coffee,orjuice?2)either…or意思为"或者……或者……"。注意谓语动词采用就近原则。EitheryouorIamright.3)orelse/otherwise否则Besilent,orelseyouwillbekickedout.Iamtired,otherwise,Iwouldplay.第三类表示转折或对比关系的连词1)but但是Heisrichbutunhappy.while然而,表示对比意味Somepeoplelovecats,whileothershatethem.yet然而Shesaidshewouldbelate,yetshearrivedontime.however然而,可是,不过Shedoesnotlikehim,however,Ilikehim.2)not…but…意思为"不是……而是……"not和but后面的用词要遵循一致原则。Theywerenotthebonesofananimal,but(thebones)ofahumanbeing.3典型例题---Wouldyouliketocometodinnertonight?---I'dliketo,___I'mtoobusy.A.andB.soC.asD.but答案D。but与前面形成转折,符合语意。而表并列的and,结果的so,原因的as都不符合句意。第四类表因果关系的连词1)for因为,做并列连词使用时,是在对先行的句子补述原因或者理由,只可以连接句子与句子,通常不置于句首。Heisabsenttoday,forheisill.2)so,therefore因此Hehurthisleg,sohecouldn'tplayinthegame.Ithink,thereforeIam3)then那么,因而Hidebehindthewall,thentheywon’tseeyou.注意:a.两个并列连词不能连用,但therefore,then,yet.可...
