Bbut Cbeside Dbesides解析：A、B两项except等于but，意为"除了…"，C-beside意为"在…旁边"，不符合题意。而D-besides,意为"除了…之外，还有"。所以该题正确答案为D。该题意为：除了英语外，你还知道别的语言吗？例2Hesuddenlyreturned____arainynight.Aon Bat Cin

并列连词用来连接并列关系的词、短语或分句，如and,for,or,both…and,either…or,neither…nor等。(2) 从属连词用来引导从句，如that,if,whether,when,after,assoonas等。除了从属连词(引导状语从句)外，还有其它可以用来引导从句的词类。它们是连接代词和连接副词(引导名词性从句)，关系代词和关系副词(引导定语从句)。2、常用连词举例(1) and和，并且Theydrankandsangallnight.(2)

or或者，否则Hurryup,oryou'llbelate.Areyouaworkeroradoctor?(10)so因此，所以It'sgettinglate,soImustgo.(11)although虽然Althoughitwaslate,theywentonworking.(12)assoonas一…就I'lltellhimassoonasIseehim.(13)because因为Hedidn'tgotoschool,becausehewasill.(14)unless除非，如果不Iwon'tgounlessitisfinetomorrow.(15)until直到…Hedidn'tleaveuntileleven.(瞬间动词用于not…until结构)Hestayedthereuntileleven.(16)while当…时候，而(表示对比)WhileIstayedthere,Imetafriendofmine.(while后不可用瞬间动词)Mypenisredwhilehisisblue.(17)for因为Hewasill,forhedidn'tcome.(结论是推断出来的)(18)since自从…Ihavelivedheresincemyuncleleft.(19)hardly…when一…就Ihadhardlygottothestationwhenthetrainleft.(20)asfaras就…来说AsfarasIknow,thatcountryisverysmall.Youmaywalkasfarasthelake.(一直走到湖那里)II．例题例1Johnplaysfootball____,ifnotbetterthan,David.Aaswell

动词时态、语态I．要点1、一般现在时(1)表示经常发生的动作或现在存在的状态，常与sometimes,always,often,everyday等时间状语连用。如：Sometimes,wegoswimmingafterschool.(2)表示客观真理、科学事实等。如：Theearthgoesroundthesun.2、现在进行时(1) 表示说话时或现阶段正在进行的动作，常与now,atpresent等时间状语连用。如：Whatareyoudoingnow?(2) 和always,continually等连用，表一种经常反复的动作，常含有某种情感。如：Heisalwaysdoinggooddeeds.3、现在完成时主要表示动作发生在过去，对现在仍有影响，或动作一直延续到现在，或可能还要继续下去，常与just,already,sofar,once,never等词连用。如:HaveyoueverbeentoBeijing?4、 一般将来时表示将来某一时间要发生的动作或存在的状态，常与tomorrow,nextyear等连用。如：I'llmeetyouattheschoolgatetomorrowmorning.We'regoingtoseeafilmnextMonday.5、 一般过去时表示在过去某一时间或某一阶段内发生的动作或存在的状态，常与yesterday,lastyear,in1998,amomentago等词连用。如：Ithappenedmanyyearsago.6、 过去进行时表示过去某一时刻或某一时期正在发生的动作。如：Whatwereyoudoingthistimeyesterday?7、过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。如：Thetrainhadalreadyleftbeforewearrived.８、一般过去将来时表示说话人从过去的角度来看将来发生的动作。如：Hesaidhewouldcome,buthedidn't.９、被动语态被动语态的时态，以give为例。II． 例题例１Ilearnedthatherfather____in1950.Ahaddied Bdied Cdead Disdead解析：该题正确答案为Ｂ。从句中的谓语动词动作虽然发生在主句谓语动词的动作之前，但因从句中有明确的过去时间状语in1950,所以不用过去完成时态，而用一般过去时态。例２Thefive-year-oldgirl____byherparents.Aislooked Bhaslookedfor Cisbeinglookedfor Dhasbeenlooked解析：该题正确答案为Ｃ。在带有介词的动词短语用于被动语态句中，介词不能省，否则就变成了不及物动词短语，而不能用于被动语态的句子中。(五) 动词虚拟语气I．要点表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。虚拟语气的构成情景条件从句的谓语动词主句的谓语动词与现在事实相反动词过去式(be要用were)should+动词原形would与过去事实相反had+过去分词should+have+过去分词would与将来事实相反１、动词过去时２、should+动词原形３、wereto+动词原形should＋动词原形would如：与现在事实相反IfIhadmoretime,IshouldstudyGerman.(fact:Ihavenomoretime,soIshallnotstudyGerman.)Ifshewerenotsobusy,shewouldattendthemeetingthisafternoon.(fact:sheisverybusy,soshewillnotattendthemeetingthisafternoon.)Iftheydidn’ttakephysicalexerciseseveryday,theywouldn’tbesohealthy.(fact:theytakephysicalexerciseseveryday,sotheyareveryhealthy.)与过去事实相反：IwouldhavecheckedmypaperagainifIhadhadmoretimeatyesterday’sexamination.(fact:Ihadnomoretimeatyesterday’sexam,soIdidn’tcheckmypaperagain)Youwouldhavealreadyrecoveredfromhisillnessifhehadseenthedoctoringoodtime.(fact:Hedidn’tseethedoctoringoodtime,sohehasn’trecoveredfromhisillness)与将来事实相反：Ifitrainstomorrow,ourpicnicwillbeputoff.(Theweatherhasbeenchangeablethesedays.)Ifitrainedtomorrow,ourpicnicwouldbeputoff.(Theweatherhasbeenverygoodthesedays.)Ifitshouldraintomorrow,ourpicnicwouldbeputoff.(Thatwouldbeoutofourexpectation.)Ifitweretoraintomorrow,ourpicnicwouldbeputoff.(条件从句谓语动词用wereto+动词原形，表示下雨的可能性极小。Weretorain和shouldrain都表示“出乎意料之外”，但wereto加强表示“当初没想到以后的事”)注：(1) 如果条件从句谓语动词包含有were或had,should,could有时可将if省去,但要倒装。如：Hadyou(Ifyouhad)invitedus,wewouldhavecometoyourparty.(2) 混合时间条件句的用法：有时条件从句的动作和主句动作发生的时间不一致。这时动词的形式，应根据它所要表达的具体时间来决定用什么形式。1)Ifshehadn’ttrainedsohard,shewouldn’tberunsofast.(从句叙述过去，主句叙述现在。)(fact:shehastrainedveryhard,soshewouldabletorunfast.)2)YouwouldspeakEnglishwellenoughifyouhadpractisedreadingandspeakingiteveryday.(主句叙述现在，从句叙述过去)(fact:Youdidn’tpractice(hasn’tpracticed)readingandspeakingiteveryday,soyoucan’tspeakEnglishwellenough.)(3) 在其他状语从句中的用法主要用于由asif(asthough)引导的比较状语从句，从句中谓语动词一般用“动词的过去式(be变were)或had+过去分词。”如：Shelookedasifshewereill.(实际上她没有病，在这里用虚拟语气补语比喻她精神不佳)XiaoLiuspeaksEnglishsowellasifhehadstudiedinEngland.(这里用虚拟语气表现他的英语说得好)２、虚拟语气在各种从句的应用(１)在主语从句中用来表示惊奇、惋惜、理应如此等，其谓语形式是"should(可省)＋动词原形"，常用于以下三种句型中。句型一：Itisnecessary(important,natural,strange,etc)that…句型二：Itisapity(ashame,nowonder,etc)that…句型三：Itissuggested(requested,proposed,desired,etc)that…如：Itisstrangethathe(should)havedonethat.Itisapitythathe(should)besocareless.Itisrequestedthatwe(should)besocareless.(２)在宾语从句中用于suggest,propose,move,insist,desire,demand,request,order,command等动词后的宾语从句中，表间接的命令和建议。其谓语形式是"(should)+动词原形"。如：Isuggestthatwe(should)goswimming.(３)在表语从句中，表示间接的命令，要求、请求、建议、决定等，主句中的主语通常是suggestion,proposal,request,orders,idea等。从句谓语形式是"(should)＋动词原形"。如：Hissuggestionisthatwe(should)leaveatonce.(４)在同位语从句中，谓语形式是"(should)＋动词原形"。如：Wereceivedorderthattheworkbedoneatonce.(５)在Itistimethat…句型中，其谓语动词形式是"动词的过去式"或"should＋动词原形",should不可省。如：It'stime(that)wewent(shouldgo)toschool.II．例题例１Wehadhopedthathe____longer.Astays Bhavestayed Cstayed Dwouldstay解析：该题正确答案为Ｄ。hadhoped表示"本希望"，同样用法的动词还有think,expect等，后面的句子需用虚拟语气例２"Marywantstoseeyoutoday"."Iwouldrathershe____tomorrowthantoday."Acomes Bcame Cshouldcome Dwillcome解析：该题正确答案为Ｂ。wouldrather后面的从句需用虚拟语气，用动词过去时表示。例３Hadshebeenolder,she____itbetter.Ahaddone Bmighthavedone Cmightdo Dwoulddo解析：Hadshebeenolder=Ifshehadbeenold.故该题正确答案为Ｂ。(六) 短语动词I．要点英语中有许多短语动词在意义上是一个整体，其用法有的相当于及物动词，有的相当于不及物动词，有的兼有及物动词和不及物动词的特征。英语短语动词的构成主要有以下六种：(１)动词＋介词常见的有lookfor,lookafter,sendfor,careabout,askfor,laughat,hearof(from),addto,leadto等。这类短语动词的宾语只能放在介词后。如：Don'tlaughatothers.Ididn'tcareaboutit.(２)动词＋副词常见的有giveup,pickup,thinkover,findout,handin,pointout等。这类短语动词的宾语如果是名词，既可放在副词前边，又可放在副词后边；宾语如果是人称代词或反身代词，则要放在副词前边。如：You'llhandinyourhomeworktomorrow.Pleasedon'tforgettohanditin.(３)动词＋副词＋介词常见的有lookdownupon,goonwith,breakawayfrom,addupto,catchupwith等。这类短语动词的宾语只能放在介词后边。如：Allhismoneyaddeduptonomorethan$100.Afterashortrest,hewentonwithhisresearchwork.(４)动词＋名词＋介词常见的有takecareof,makeuseof,payattentionto,makefunof等。这类短语动词的宾语只能放在介词后边。如：Youshouldpayattentiontoyourhandwriting.Weshouldmakefulluseofourtime.(５)动词＋形容词常见的有leaveopen,setfree,cutopen等。这类短语动词的宾语如果是名词，则宾语可放在形容词的前边，也可放在后边；宾语如果是人称代词或反身代词，则必须放在形容词前边。如：Theprisonersweresetfree.Hecutitopen.(６)动词＋名词常见的有takeplace,makefriends等。这类短语动词用作不及物动词。如：Thisstorytookplacethreeyearsago.Imakefriendswithalotofpeople.(7) 辨析giveaway(让给，暴露)和giveup(放弃，停止)putaway(放起，收起)和putout(扑灭)turnup(出席，放大)和turnon(打开)keepout(阻止)和keepoff(不让靠近)makeup(编造，补上)和makeout(辨认)takeoff(脱，起飞)和takeout(拿出)II．例题例１Itiswisetohavesomemoney____foroldage.Aputaway Bkeptup Cgivenaway Dlaidup解析：该题正确答案为Ａ。意为"存"；keepup意为"继续"；giveaway意为"分发"；layup"贮藏"。例２Here'smycard.Let'skeepin____.Atouch Brelation Cconnection Dfriendship解析：该题正确答案为A.keepintouch为短语动词，意为"保持联系"。例３____!There'satraincoming.ALookout BLookaround CLookforward DLookon解析：该题选A.lookout意为"小心"。(七) 动词不定式I．要点１、不定式的形式。以动词write为例。２、不定式的句法功能(１)作主语Tohearfromyouisnice.Tobeagoodteacherisnoteasy.不定式作主语时，为了保持句子的平衡，往往以it作形式主语，而不定式置于谓语动词后。如：It'snicetohearfromyou.It'snoteasytobeagoodteacher.(２)作宾语通常用于want,hope,wish,like,need,hate,begin,start,remember,agree,learn,pretend,refuse,manage,help等词后。如：Iforgottolockthedoor.Pleaseremembertowritetome.(３)作表语Myjobistopickupletters.Heseemedtohaveheardnothing.(４)作定语不定式作定语时，须放在它所修饰的名词或代词后。如：Ihavetwoletterstowrite.Ihavealotofworktodo.(５)作宾补通常用于want,wish,ask,order,tell,know,help,advise,allow,cause,force等词后。如：Heorderedhertoleaveatonce.Hewasforcedtoobeyhisorder.(６)作状语Hegotupearlytocatchthefirstbus.Heworkedhardtocatchupwiththeotherstudents.(７)作独立成分Totellyouthetruth,Itoldalie.(８)"疑问词＋不定式"结构。如：Idon'tknowhowtochoosethem.Icannotdecidewheretogo.(9) 不定式的否定式。如：Idecidednottogo.(10) 不定式的完成式。如：HeseemedtohavecleanedtheroombeforeIcamein.Theboyissaidtohavebeensenttothehospitallastweek.(11) too…to结构。如：Hewastooexcitedtogotosleep.Hewasonlytoogladtogo.(他太高兴了，乐意去)(12) 主动表被动。如：Thebookiseasytoread.Ihaveabooktoread.II． 例题例１Ihaven'tgotachair____.Atosit Bfortositon Ctositon Dforsitting解析：该题选C。不定式tositon在句中作定语，修饰名词chair.因为不定式和它所修饰的名词间是"动宾关系"，所以不定式必须是及物动词，故此处on不能省略。例2Hewasmade____.Ago Bgone Cgoing Dtogo解析：该题选D。makesb.dosth.如果是被动形式，不定式do前的to不能省略。例3Anewfactoryis____verysoon.Atobebuilt Bbuilt Ctobuild Dtobuilding解析：该题选A。istobebuilt意为"将要被建"。(八) 动名词I．要点动名词既具有动词的一些特征，又具有名词的句法功能。１、动名词的形式，以write为例。否定式not+动名词２、动名词的用法(１)作主语Playingfootballismyfavoritesport.Travellingwithfriendsatweekendisfun.作主语的动名词结构复杂且长时，可用it作形式主语。如：Itisfuntravellingwithfriendsatweekend.(２)作宾语IenjoyplayingPCgame.Hegaveupwritingfiveyearsago.(３)作表语Whathehatedmostwasdoingnothing.Seeingisbelieving.动名词作表语时，句子的主语常是无生命名词或what引导的名词性从句。(４)作定语There'sadiningroominmyschool.Allthepeoplewatchinglaughed.(５)动名词的复合结构"物主代词(或名词的所有格)+动名词"。如：Tom'sgoinghomelatemadehermotherangry.Wouldyoumindmyopeningthewindow?不过，动名词的逻辑主语在遇到以下情况时，必须用名词的普通格(或人称代词的宾格)。① 无生命名词Thegirlswereafraidofthedoorsuddenlyclosing.Fireburnsbetterbyoxygenbeingatwork.② 有生命名词，但表泛指。Haveyoueverheardofgirlssmoking?③ 两个以上的有生命的名词并列。Doyoustillremembermyparentsandmecomingtoseeyouthatday? 3． 后面常接动名词的动词和短语mind,enjoy,finish,consider,practise,imagine,keep,suggest,advise,allow,permit,beworthdoing,beusedtodoing,bebusydoing,can'thelpdoing,itisnogooddoing,itisnousedoing,lookforwardtodoing,sticktodoing,payattentiontodoing,devotetodoing,leadtodoingII． 例题例１Shesaysshedoesn'tfeellike____outwithyou.Agoing Btogo Cforgoing Dwent解析：该题正确答案为A。feellike=want,此处like为介词，后面要接名词或动名词作宾语例２Thegardenneeds____.Awater Bwatering Ctowater Dwatered解析：该题正确答案为B。need=want=require.如果物作主语，此三者后要接动名词或tobedone这一结构作宾语。例３Excuseme____you.Ainterrupting Btointerrupt Cinterrupted Dtohaveinterrupted解析：该题正确答案为A。excuse后接动名词作宾语，此句中的me为动名词的逻辑主语(常用于口语中)。(九) 分词I． 要点分词既具有动词的一些特征，又具有形容和副词的句法功能。它分为现在分词和过去分词两类。现在分词和过去分词的主要差别在于现在分词有一般式和完成式，过去分词则只有一般式。现在分词表动作正在进行，表主动。过去分词及物动词表动作已经完成，表被动。过去分词不及物动词表动作已经完成，表主动。过去分词的句法功能：１、作定语IliketoreadthenovelwrittenbyLuXun.Thewomansittingbesidethebrokenwindowwasafriendofmine.２、作表语WhenIcameintotheroom,Ifoundthewindowwasbroken.I'minterestedinthisbook.３、作宾语补足语I'mgoingtohavemybikerepaired.WhenIwalkedhome,Isawthethiefcaughtbythepolice.4、 作状语Seenfromthetopofthemountain,thecitylookssmall.Theteachercameintotheclassroom,followedbyhisstudents.现在分词的句法功能。1、

作表语Seeingisbelieving.Thebookisinteresting.4、 作宾语补足语Inoticedhimcrossingthestreet.Mothercaughthimsmokinginthekitchen.5、 作定语Doyouknowthemanwritingaletter?Theworkerrunningamachineismybrother.分词使用中的几个问题1、 现在分词的完成式
