现在进行时讲解及试题答案

小学英语语法之现在进行时详解、练习、答案一、概念现在进行时表示说话时正在进行或发生的动作,也可表示当前一段时间内的活动或现阶段正在进行的动作结构：助动词be(am/is/are)+现在分词.二、现在分词的构成：1.大多数动词后可在动词后直接加-ingEg:carry-carrying,catch-catching,drink-drinking,enjoy-enjoyinghurry-hurrying,do-doing,read-reading,think-thinking2.如果动词以-e结尾,则去掉-e,再加-ing,如come-coming,have-having,make-making,ride-riding,write-writing,take-taking,use-using3.如果动词只有一个元音字母,而其后跟有一个辅音字母时,将此辅音字母双写,再加-ing如：hit-hitting, let-letting,put-putting, run-running, sit-sitting4.如果动词有两个音节,且重音在第二个音节上,则末尾的辅音字母须双写,再加-ing,如:forget-forgetting,prefer-preferring,upset-upsetting试比较benefit/benfiting,differ/differing,profit/profiting,这些词的重音在第一个音节上,因此其末尾的辅音字母不双写5.以-ic结尾的动词,应先把-ic变为-ick,再加-ing,eg:panic/panicking,picnic/picnicking,但lie/lying,die/dying,tie/tying是特殊变化要记住三、句型结构：1.现在进行时的肯定形式、否定形式、疑问形式及其回答,所有变化都体现在助动词be(is/am/are)上1)现在进行时的肯定形式：主语+be(am/is/are)+doing+其他成分Iamsinging.Theyarewriting.2)现在进行时的否定形式:主语+be(am/is/are)+not+doing+其他成分Iamnotsinging.Theyarentwriting.3）一般疑问句及回答：be(am/is/are)+主语+doing+其他成分AmIsinging?Yes,youare./No, youarent.Aretheywriting?Yes,theyare./No, theyarent.4)特殊疑问句及回答:特殊疑问词+be(am/is/are)+主语+doing+其他成分Whatareyoudoing?Weareplaying(要求就提问内容具体回答).2.缩写形式如下:Iam-Im Youare-Youre Heis-Hes Sheis-ShesItis-Its Weare-Were Theyare-Theyre3.说明:不是所有动词都能用现在进行时态的,如：see、like、want、know等动词往往都不用进行时态四用法：1.表示现在(指说话人说话时)正在发生的事情往往与now,atthemoment,just等副词连用,以示强调Wearewaitingforyou.Whatareyoudoing?Someonesknockingatthedoor2.正在进行着的动作可视为未完成的动作：Hestalkingtohisfriendsintheclassroom.可用still一词强调动作的持续性Hesstilltalkingtohisfriendsintheclassroom.3.表示长期的或重复性的动作,说话时动作未必正在进行Mr.Blackiswritinganotherarticle.Donttakethatbookaway.Yourfathersusingit.SheislearningpianounderMr.Black.4.现在进行时可用来表示不会长期发生的动作或情况,或被认为在短期内正在进行的动作或存在的情况：Whatsyourbrotherdoingthesedays?HesstudyingEnglishatOxfordUniversity.5.现在进行时也可以用来表示当前的动向：Peoplearebecomingmoreandmorebeautifulthesedays.6.表示渐变的动词有：become,turn,get,grow,run,go,begin等Theleavesareturningbrown.Itsgettingcolderandcolder.7.与always,constantly,forever等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩Youarealwayschangingyourmind.8.现在进行时(以及begoingto）可以表示为将来安排好的活动和事件WerespendingnextwinterinChina.用arrive,come,go,leave等动词的现在进行时描写行程安排,也通常有“将到达”和“将离去”的意思：Hesarrivingtomorrowmorning.9.当现在进行时表示某事发生的次数过多时,则有时含有抱怨,讨厌,赞扬等的意思：Heisalwayssingingatnight,andwecantfallasleeplateatnight.练习一.用现在进行时完成下列句子:1._you_(fly)akite?Yes,_.2._you_(sit)intheboat?3._he_(talk)withme?4.We_(play)footballnow.5.What_you_(do)?6.I_(sing)anEnglishsong.7.What_he_(mend)?8.He_(mend)acar.9.Theseboys_(play)tennisontheplayground.10.Mymother_(cook)inthekitchen.11.Wecanthelpyou,becausewe_(have)classes.12._theboy_(write)hishomework?13.Look!Thesebutterflies_(fly)inthesky.14.Listen!Thegirl_(sing)inthenextroom.15.Thenaughtyboy_(swim)intheriver.二.选择1.Look.Lucyis_anewbiketoday.A.jumpingB.runningC.ridingDtakeing2.Thechildren_football.A.isplayingB.areplayingC.playtheD.playa3.They_TVintheevening.Theydotheirhomework.A.arewatchingB.cantwatchingC.dontwatchD.dontwatching4.Listen!She_intheclassroom.A.issingingB.singC.tosingD.issing5._areyoueating?Imeating_meat.A.What,someB.Which,anyC.Where,notD.What,a6.Isshe_something?A.eatB.eatingC.eattingD.eats7.Mydictionary_,Ihavelookedforiteverywherebutstill_it.A.haslost,dontfindB.ismissing,dontfindC.haslost,haventfoundD.ismissing,haventfound.8.Havingacomputerforpersonaluseisnoeasytaskbecausetechnology_sorapidly.A.ischangingB.haschangedC.willhavechangedD.willchange9.Thebuilding_,Icantstandthenoise.A.wasbeingbuiltB.isbuiltC.isbeingbuiltD.builds10.Icantcatchupwiththefashion, becausetheclothesstyle_allthetime.A.haschangedB.ischangedC.ischangingD.changed11.Itssixintheafternoon.TheGreens_lunchtogether.A.hasB.arehavingC.havehadD.hadhad12.Dontmakeanynoisewhilethestudents_totheclass.A.arelisteningB.listenedC.havelistenedD.hadlistened13.JackandKetty_inthelake.Letsjointhem,shallwe?A.swimB.haveswumC.swamD.areswimming14.Look!Thechildren_basketballontheplayground.A.playsB.playedC.isplayingD.areplaying15.Thekite_highintheskynow.Itlookslikeabigbird.A.hasflownB.isflyingC.wasflyingD.flew16.Asweallknow,thepopulationintheworld_fasterandfaster.A.isgrownB.isgrowingC.aregrownD.aregrowing17.Tomysurprise,he_inclass.A.isalwaysspeakingB.wouldalwaysspeakC.hasalwaysbeenspeakingD.doesspeakalways18.Iwanttoknowwhenhe_forNewYorktomorrow.A.hasleftB.isleavingC.hadleftD.hasbeenleaving19.He_ofhowhecandomoreforthepeople.A.hadalwaysthoughtB.isalwaysthinkingC.hasalwaysbeenthoughtD.thinkingalways20.Forests_andburnedatsuchaspeedthattheywilldisappearfromtheearthinthefuture.A.cutB.arecutC.arebeingcutD.hadbeencut答案：1.Are,flying,Iam2.Aresitting,3.Is,talking4.areplying5.are,doing6.amsinging7.is,mending8.ismending9.areplying10.iscooking11.arehaving12.Is,writing13.areflying14.issinging,15.isswimming1.C2.B3.C4.A5.A6.B7.D8.A9C10.C11.B12.A13.D14.D15.B16.B17.A18.B19.B20.C
