牛津小学英语5A现在进行时练习题及答案

牛津英语5A英语语法(四)现在进行时一、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-ing．Eg: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-using．3.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-sitting．4.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:for’get-forgetting,pre’fer-preferring,up’set-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.Theyaren’twriting.3）一般疑问句及回答：be(am/is/are)+主语+doing+其他成分AmIsinging?Yes,youare./No,youaren’t.Aretheywriting?Yes,theyare./No,theyaren’t.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---I’mYouare---You’reHeis---He’sSheis---She’sItis---It’sWeare---We’reTheyare---They’re3.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?Someone’sknockingatthedoor．2.正在进行着的动作可视为未完成的动作：He’stalkingtohisfriendsintheclassroom.可用still一词强调动作的持续性He’sstilltalkingtohisfriendsintheclassroom.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.Don’ttakethatbookaway.Yourfather’susingit.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：What’syourbrotherdoingthesedays?He’sstudyingEnglishatOxfordUniversity.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.It’sgettingcolderandcolder.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We’respendingnextwinterinChina.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：He’sarrivingtomorrowmorning.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,andwecan’tfallasleeplateatnight.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.Wecan’thelpyou,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.can’twatchingC.don’twatchD.don’twatching4.Listen!She____intheclassroom.A.issingingB.singC.tosingD.issing5.______areyoueating?I’meating______meat.A.What,someB.Which,anyC.Where,notD.What,a6.Isshe____something?A.eatB.eatingC.eattingD.eats7.Mydictionary___,Ihavelookedforiteverywherebutstill___it.A.haslost,don’tfindB.ismissing,don’tfindC.haslost,haven’tfoundD.ismissing,haven’tfound.8..Havingacomputerforpersonaluseisnoeasytaskbecausetechnology_______sorapidly.A.ischangingB.haschangedC.willhavechangedD.willchange9.Thebuilding_______,Ican’tstandthenoise.A.wasbeingbuiltB.isbuiltC.isbeingbuiltD.builds10.Ican’tcatchupwiththefashion,becausetheclothesstyle_______allthetime.A.haschangedB.ischangedC.ischangingD.changed11.It’ssixintheafternoon.TheGreens_______lunchtogether.A.hasB.arehavingC.havehadD.hadhad12.Don’tmakeanynoisewhilethestudents_______totheclass.A.arelisteningB.listenedC.havelistenedD.hadlistened13.JackandKetty_______inthelake.Let’sjointhem,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.hadbeencut1.Are,flying,Iam2.Aresitting,3.Is,talking4.areplying5.are,doing6.amsinging7.is,mending8.ismending9.areplying10.iscooking11.arehaving12.Is,writing13.arefly
