等。afraidof,angrywith,differentfrom,goodat和名詞的搭配，如answerto,keyto,reasonfor,causeof,visitto 等.3、介詞短語可以有自己的修飾語，這種修飾語通常有right,just,badly,all,well,directly,completely等少數(shù)幾個副詞。如：Hecamerightafterdinner.Helivesdirectlyoppositetheschool.4、某些介詞的意義與用法舉例at,on,in（表時間）at,如atfouro'clock,atmidnightat,如thattime,atChristmas等。指某天用on,如onMonday,ontheendofNovember, 指某天的朝夕用on,如onmorning,ontheafternoonofSeptemberlst 等。指長于或短于一天的時段用如intheafternoon,inFebruary,inSummer,in1999 等。between,among（表位置）betweenbetween,如4I'msittingbetweenTomandAlice.Thevillageliesbetweenthreehills.among用于三者或三者以上之間。如：Heisthebestamongthestudents.beside,besidesbeside意為"在旁邊"besides意為"除…之外"。如：Hesatbesideme.Whatdoyouwantbesidesthis?inthetree,onthetreeinthetree指動物或人在樹上，而onthetree

English?AexceptBbutCbesideDbesides解析：A、B兩項except等于but，意為"除了…"，C-beside意為"在旁邊"，不符合題意。而D-besides, 意為"除了之外，還有"。所以該題正確答案為D。該題意為：除了英語外，你還知道別的語言嗎？例2Hesuddenlyreturned arainynight.AonBatCinDduring解析：我們均知道，atnightnight詞on來修飾，故該題正確答案為A。例3I'mlookingforward yourletter.AtoBinCatDon解析：該題正確答案為A。lookforwardto為固定搭配，意為"期望、盼望"。5（三）連詞要點1、連詞的種類并列連詞用來連接并列關(guān)系的詞、短語或分句，如and,for,or,both…and,either…or,neither…nor等。從屬連詞用來引導(dǎo)從句，如that,if,whether,when,after,assoonas 等。除了從屬連詞（引導(dǎo)狀語從句）外，還有其它可以用來引導(dǎo)從句的詞類。它們是連接代詞和連接副詞（引導(dǎo)名詞性從句），關(guān)系代詞和關(guān)系副詞（引導(dǎo)定語從句）。2、常用連詞舉例and和，并且Theydrankandsangallnight.both…and和，既…也…BothmyparentsandIwentthere.but但是，而I'msad,butheishappy.either…or或…或…，要么…要么…Eitheryou'rewrong,orIam.for因為Iaskedhimtostay,forIhadsomethingtotellhim.however然而，可是Affirst,hedidn'twanttogothere.Later,however,hedecidedtogo.neither…nor既不…也不Neithermyparentsnormyauntagreeswithyou.notonly…but(also) 不但而且…Henotonlysingswell,butalsodanceswell.or或者，否則Hurryup,oryou'llbelate.Areyouaworkeroradoctor?6so因此，所以It'sgettinglate,soImustgo.although 雖然Althoughitwaslate,theywentonworking.assoonas …就I'lltellhimassoonasIseehim.because 因為Hedidn'tgotoschool,becausehewasill.unless除非，如果不Iwon'tgounlessitisfinetomorrow.until直到…Hedidn'tleaveuntileleven.(not…until結(jié)構(gòu)Hestayedthereuntileleven.while當(dāng)…時候，而表示對比)WhileIstayedthere,Imetafriendofmine.(while

shallwegetdowntobusinessrightaway?A.andB.thenC.orD.otherwise解析：該處意為"或者"，正確答案為C。英語語法知識難點（二）（四）動詞時態(tài)、語態(tài)要點1、一般現(xiàn)在時表示經(jīng)常發(fā)生的動作或現(xiàn)在存在的狀態(tài)，常與sometimes,always,often,everyday 等時狀語連用。如：Sometimes,wegoswimmingafterschool.表示客觀真理、科學(xué)事實等。如：Theearthgoesroundthesun.2、現(xiàn)在進行時表示說話時或現(xiàn)階段正在進行的動作，常與now,atpresent等時間狀語連用。如：Whatareyoudoingnow?和always,continually等連用，表一種經(jīng)常反復(fù)的動作，常含有某種情感。如：Heisalwaysdoinggooddeeds.3、現(xiàn)在完成時主要表示動作發(fā)生在過去，對現(xiàn)在仍有影響，或動作一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去常與just,already,sofar,once,never

begiven havebeengivenwillshouldwillshould過去將來begivenhavebeengivenwouldwouldamamhas現(xiàn)在isaregivenisarebeingbeengivenhavewaswas例題例１Ilearnedthatherfather in1950.AhaddiedBdiedCdeadDisdead解析：該題正確答案為Ｂ。從句中的謂語動詞動作雖然發(fā)生在主句謂語動詞的動作之前，但因從句中有明確的過去時間狀語in1950,所以不用過去完成時態(tài)，而用一般過去時態(tài)。例２Thefive-year-oldgirl byherparents.AislookedBhaslookedforCisbeinglookedforDhasbeenlooked解析：該題正確答案為Ｃ。在帶有介詞的動詞短語用于被動語態(tài)句中，介詞不能省，否則就變成了不及物動詞短語，而不能用于被動語態(tài)的句子中。9（五）動詞虛擬語氣要點一般常用于正式的書面語中。１、虛擬語氣的構(gòu)成情景情景條件從句的謂語動詞主句的謂語動詞should（bewere）+動詞原形wouldshouldhad過去分詞+have+過去分詞１、動詞過去時與將來事實相反２、should+動詞原形３、wereto+動詞原形wouldshould＋動詞原形would注：如果條件從句謂語動詞包含有were或had,should,couldif省去,但要倒裝。如：Hadyou(Ifyouhad)invitedus,wewouldhavecometoyourparty.２、虛擬語氣在各種從句的應(yīng)用（１）在主語從句中用來表示驚奇、惋惜、理應(yīng)如此等，其謂語形式是"should(可省)＋動詞原形"，常用于以下三種句型中。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）在賓語從句中用于suggest,propose,move,insist,desire,demand,request,order,command等動詞后的賓語從句中，表間接的命令和建議。其謂語形式是"(should)+動詞原形"。如：Isuggestthatwe(should)goswimming.（３）在表語從句中，表示間接的命令，要求、請求、建議、決定等，主句中的主語通常是suggestion,proposal,request,orders,idea

故該題正確答案為Ｂ。（六）短語動詞要點英語中有許多短語動詞在意義上是一個整體，其用法有的相當(dāng)于及物動詞，有的相當(dāng)于不及物動詞，有的兼有及物動詞和不及物動詞的特征。英語短語動詞的構(gòu)成主要有以下六種：（１）動詞＋介詞常見的有l(wèi)ookfor,lookafter,sendfor,careabout,askfor,laughat,hearof(from),addto,leadto等。這類短語動詞的賓語只能放在介詞后。如：Don'tlaughatothers.Ididn'tcareaboutit.（２）動詞＋副詞常見的有g(shù)iveup,pickup,thinkover,findout,handin,pointout

.AtositBfortositonCtositonDforsittingtositon在句中作定語，修飾名詞chair.詞間是"動賓關(guān)系"，所以不定式必須是及物動詞，故此處on不能省略。例2Hewasmade .14AgoBgoneCgoingDtogo解析：該題選D。makesb.dosth. 如果是被動形式，不定式do前的to不能省略。例3Anewfactoryis veryAtobebuiltBbuiltCtobuildDtobuildingA。istobebuilt意為"將要被建"。（八）動名詞要點動名詞既具有動詞的一些特征，又具有名詞的句法功能。１、動名詞的形式，以write為例。|一般式主動語態(tài)被動語態(tài)完成式writinghavingwrittenbeingwrittenhavingbeenwritten否定式not+動名詞２、動名詞的用法（１）作主語Playingfootballismyfavoritesport.Travellingwithfriendsatweekendisfun.作主語的動名詞結(jié)構(gòu)復(fù)雜且長時，可用it作形式主語。如：Itisfuntravellingwithfriendsatweekend.（２）作賓語IenjoyplayingPCgame.Hegaveupwritingfiveyearsago.（３）作表語Whathehatedmostwasdoingnothing.Seeingisbelieving.動名詞作表語時，句子的主語常是無生命名詞或what引導(dǎo)的名詞性從句。（４）作定語There'sadiningroominmyschool.Allthepeoplewatchinglaughed.（５）動名詞的復(fù)合結(jié)構(gòu)"物主代詞（或名詞的所有格）+動名詞"。如：15Tom'sgoinghomelatemadehermotherangry.Wouldyoumindmyopeningthewindow?不過，動名詞的邏輯主語在遇到以下情況時，必須用名詞的普通格（或人稱代詞的賓格）。①無生命名詞Thegirlswereafraidofthedoorsuddenlyclosing.Fireburnsbetterbyoxygenbeingatwork.②有生命名詞，但表泛指。Haveyoueverheardofgirlssmoking?③兩個以上的有生命的名詞并列。Doyoustillremembermyparentsandmecomingtoseeyouthatday?mind,enjoy,finish,consider,practise,magine,keep,suggest,advise,allow,permit,beworthdoing,beusedtodoing,bebusydoing,can'thelpdoing,itisnogooddoing,itisnousedoing,lookforwardtodoing,sticktodoing,payattentiontodoing,devotetodoing,leadtodoing例題例１Shesaysshedoesn'tfeellike
