usedto过去常常（现在已不再）usednot/usedn’t/usen’ttododidn’tusetodoUsed…todo…?Yes,…used.No,…use(d)n’t.Did…usetodo…?Yes,…did.No,…didn’t.II.情态动词must,may,might,could,can表示推测：以must为例。must+do(be)是推测现在存在的一般状态进行；must+bedoing推测可能正在进行的事情；must+havedone是推测可能已经发生过的事情。1.must“肯定，一定”语气强，只用于肯定句中。HemustbeamanfromAmerica./Hemustbetalkingwithhisfriend./Hemusthavealreadyarrivedthere.2.may和might“也许”，后者语气弱，更没有把握。可用于肯定句和否定句。Hemaynotbeathome./Theymighthavefinishedtheirtask.3.can和could“可能”，could表示可疑的可能性，不及can’t语气强，用于肯定、否定、疑问句中。Theweatherinthatcitycouldbecoldnow.Wecouldhavewalkedthere;itwassonear.（推测某事本来可能发生，但实际上没有发生）Canhebeintheofficenow?No,hecan’tbethere,forIsawhiminthelibrary justnow.(语气很强，常用于疑问句和否定句中)III.情态动词注意点：1.can和beableto:都可以表示能力。但beableto可以表达“某事终于成功”，而can无法表达此意。Beableto有更多的时态。另外，两者不能重叠使用。2.usedto和would:usedto表示过去常常做现在已经不再有的习惯，而would只表示过去的习惯或喜好，不涉及现在。3.need和dare作情态动词和实义动词的区别：两者作情态动词时常用于否定句和疑问句。其形式为：needn’t/daren’tdo；Need/dare…do…?做实义动词时可用于肯定句，否定句和疑问句。其形式为：need(needs/needed)/dare(dares/dared)todo,don’t(doesn’t/didn’t)need/daretodo八．非谓语动词I.非谓语动词的分类、意义及构成：非谓语形式构成特征和作用 时态和语态否定式复合结构不定式todotobedoingtohavedonetobedonetohavebeendone在非谓语前加notforsb.todosth.具有名词，副词和形容词的作用在句中做主、宾、定、表和状语分词现在分词doinghavingdonebeingdonehavingbeendone具有副词和形容词的作用在句中做定、表、宾补和状语过去分词done动名词doinghavingdonebeingdonehavingbeendonesb’sdoing具有名词的作用在句中做主、宾、定和表语II.做宾语的非谓语动词比较：情况常用动词只接不定式做宾语的动词hope,want,offer,long,fail,expect,wish,ask,decide,pretend,manage,agree,afford,determine,promise,happen 只接动名词做宾语的动词或短语mind,miss,enjoy,imagine,practise,suggest,finish,escape,excuse,appreciate,admit,prevent,keep,dislike,avoid,risk,resist,considercan’thelp,feellike,succeedin,befondof,objectto,getdownto,beengagedin,insiston,thinkof,beproudof,takepridein,setabout,beafraidof,betiredof,lookforwardto,devoteoneselfto,beworth,bebusy,payattentionto,stickto两者都可以意义基本相同begin,start,like,love,hate,prefer,continue（接不定式多指具体的动作，接动名词多指一般或习惯行为）need,want,require（接动名词主动形式表示被动意义，若接不定式则应用被动形式）意义相反stoptodo停止手中事，去做另一件事stopdoing停止正在做的事意义不同remember/forget/regrettodo（指动作尚未发生）remember/forget/regretdoing（指动作已经发生）goontodo（接着做另外一件事）goondoing（接着做同一件事）trytodo（设法，努力去做，尽力）trydoing（试试去做，看有何结果）meantodo（打算做，企图做）meandoing（意识是，意味 着）can’thelptodo（不能帮忙做）can’thelpdoing（忍不住要做）III.非谓语动词做宾语补足语的区别：常见动词与宾语的逻辑关系及时间概念例句不定式ask,beg,expect,get,order,tell,want,wish,encourage主谓关系。强调动作将发生或已经完成Iheardhimcallmeseveraltimes.have,notice,see,watch,hear,feel,let,make现在分词notice,see,watch,hear,find,keep,have,feel主谓关系。强调动作正在进行，尚未完成Ifoundherlisteningtotheradio.过去分词动宾关系。动作已经完成，多强调状态Wefoundthevillagegreatlychanged.IV.非谓语动词做定语的区别：区别举例不定式与被修饰词往往有动宾关系，一般式表示将Ihavealotofpaperstotype. 来，进行式表示与谓语动作同时发生，完成式表示在谓语动词之前发生Ihavealotofpaperstobetyped.动名词通常指被修饰词的用途，无逻辑上的任何关系Shallwegototheswimmingpool?现在分词与被修饰词之间是主谓关系，表示动作与谓语动作同时发生theboilingwater/theboiledwaterthedevelopingcountry/thedevelopedcountrythefallingleaves/thefallenleaves过去分词与被修饰词之间是被动关系，表示动作发生在谓语动作之前，现已经完成V.非谓语动词做主语和表语的区别：区别举例不定式多表示一个特定的具体的将来的动作，做主语时可以借助于it把不定式移到句子后面。做表语有时可和主语交换位置，而且意义不变，并且还能用what来提问主语或表语。Mydreamistobecomeateacher.Toobeythelawisimportant.(dream,business,wish,idea,plan,duty,task做主语时常用) 动名词与不定式的功能区别不大，然而它更接近于名词，表示的动作比较抽象，或者泛指习惯性的动作，有时也可以用it做形式主语，做表语时可以和主语互换位置。Itisnousesayingthatagainandagain.Teachingismyjob.分词无名词的性质，不能做主语。但是有形容词的性质，可以做表语，多表明主语的特征性质或者状态等，可被very,quite,rather等副词修饰。现在分词多含有“令人…”之意，说明主语的性质特征，多表示主动，主语多为物。过去分词一般表示被动或主语所处的状态，含有“感到…”之意，主语多是人。Thesituationisencouraging.Thebookiswellwritten.(常见分词有astonishing,moving,tiring,disappointing,puzzling,shocking,boring,amusing及其-ed形式)九．定语从句I.定语从句起了形容词的作用，在句中修饰一个名词或代词。被修饰的词叫做先行词，引导定语从句的词叫关系词，他的作用一是放在先行词与定语从句中间起了连接作用，二是在从句中担当一个成分，并与先行词保持数的一致。关系词例句备注 先行词从句成分关系代词who人主语Doyouknowthemanwhoistalkingwithyourmother?whom,which和that在从句中做宾语时，常可以省略，但介词提前时后面关系代词不能省略，也不可以用thatwhom人宾语Mr.SmithisthepersonwithwhomIamworkingTheboy(whom)sheloveddiedinthewar..whose人，物定语Ilikethosebookswhosetopicsareabouthistory.Theboywhosefatherworksabroadismydeskmate.that人，物主语，宾语Aplaneisamachinethatcanfly.Sheisthepopstar(that)Iwanttoseeverymuch.which物主语，宾语Thebook(which)Igaveyouwasworth$10.Thepicturewhichwasabouttheaccidentwasterrible.as人，物Heissuchapersonasisrespectedas 主语，宾语byallofus.ThisisthesamepenasIlostyesterday.做宾语一般不省略关系副词when时间时间状语Iwillneverforgetthedaywhenwemetthere.可用onwhichwhere地点地点状语ThisisthehousewhereIwasborn.可用inwhichwhy原因原因状语Ican’timaginethereasonwhyheturneddownmyoffer.可用forwhichII.that与which,who,whom的用法区别：情况用法说明例句只用that的情况1．先行词为all,everything,anything,nothing,little,much,等不定代词时。2．先行词被all,any,every,each,much,little,no,some,few等修饰时3．先行词有形容词最高级和序数词修饰时4．1.Hetoldmeeverythingthatheknows.2.Allthebooksthatyouofferedhasbeengivenout.3.ThisisthebestfilmthatIhaveeverread.4.Wetalkedaboutthepersonsandthingsthatweremembered. 先行词既指人又指物时5．先行词被theonly,thevery修饰时6．句中已经有who或which时，为了避免重复时5.HeistheonlymanthatIwanttosee.6.Whoisthemanthatismakingaspeech?只用which,who,whom的情况1．在非限制性定语从句中，只能用which指代物，用who/whom指人2．在由“介词+关系代词”引导的定语从句中，只能用which指物，whom指人。3．先行词本身是that时，关系词用which,先行词为those,one,he时多用who。Hehasason,whohasgoneabroadforfurtherstudy.Ilikethepersontowhomtheteacheristalking.Thosewhorespectothersareusuallyrespectedbyothers.III.as与which的区别：定语从句区别例句名词前有such和thesameHeisnotsuchafoolashelooks. 限制性定语从句中修饰时，关系代词用as,不能用whichDon’treadsuchbooksasyoucan’tunderstand.非限制性定语从句中as和which都可以指代前面整个主句。如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。Theywonthegame,aswehadexpected.Theywonthegame,whichwehadn’texpected.Asiswellknown,heisafamousfilmstarinthe1980s.IV.限制性定语从句与非限制性定语从句的区别：类别语法意义及特征例句限制性定语从句对先行词起修饰限制作用，如果去掉，主句意思就不完整明确，这种从句与主句的关系十分密切，写时不用逗号分开。TheaccidenthappenedatthetimewhenIleft.非限制性定语从句　对先行词作附加的说明，与主句的关系不十分密切，较松散。从句和主句之间用逗号分开，相当于一个插入语，不能用that引导，关系代词做宾语时也不能省略。Hismother,whomheloveddeeply,diedtenyearsago.十．名词性从句 种类作用常用关联词例句主语从句在复合句中做主语，相当于名词，一般置谓语之前，也可用it作形式主语，主语从句放主句之后that,whether,if,asif,asthough,who,whose,which,how,when,where,why,what,whatever,whoever,whereverWhetherhewillcomeornotdoesn’tmattermuch.Whoevercomesherewillbewelcome.表语从句在复合句中做表语，相当于名词，位于系动词之后Itlooksasifitisgoingtosnow.宾语从句在复合句中做宾语，相当于名词Heaskedmewhichteamcouldwinthegame.同位语从句放在名词之后(news,problem,idea,suggestion,advice,thought,hope,fact等)表明其具体内容Youhavenoideahowworriedweare.Thefactthatheliedagaingreatlysurprisedus.十一。状语从句种类连接词注意点时间状语when,whenever,while,as,before,after,until,till,bythetime,assoon主句表示将来意义时，从句须用一般现在时；while as,hardly…when,nosooner…than,themoment,theminute,immediately,directly,instantly引导的从句中动词一般是延续性的；until用在肯定句中主句动词是延续性的，而否定句中主句动词为短暂性的。地点状语where,wherever原因状语because,as,since,nowthatbecause语气最强，since较弱，表示大家都明了的原因，as又次之。条件状语if,unless,once,incase,aslongas,onconditionthat从句中动词时态不可用将来时，常用一般时代替目的状语sothat,inorderthat,forfearthatsothat和inorderthat后常接may,should,could,would等情态动词结果状语so…that,such…that比较状语than,as…as,notso/as…as,themore…themore方式状语asif,asthough,asasif和asthough引导的从句一般用虚拟语气。though,although,evenif,evenas在让步状语从句中常用倒装形式； 让步状语though,as,nomatterwhat,whatever,nomatterwho,whoever,nomatterwhich,whichever,nomatterhow,however,nomatterwhen,wheneveralthough和though用正常语序，可和yet连用，但不可和but连用十二。倒装句种类倒装条件例句完全倒装here,there,up,down,in,out,off,away等副词开头的句子表示强调Outrushedthechildren.表示地点的介词短语作状语位于句首Underthetreestoodtwotablesandfourchairs.强调表语，置于句首，或为保持句子平衡Presentatthemeetingwere1,000students.部分倒装never,hardly,scarcely,seldom,little,notuntil,not等表示否定意义的副词放于句首HardlydidIknowwhathadhappened.only和修饰的状语放于句首OnlythendidherealizedtheimportanceofEnglish.
