现在进行时定义现在进行时的定义:现在进行时表示现在或当前一段时间正在进行的动作。也可以表示有计划的未来,也就是用现在进行时表示将来。一、构成方法现在进行时由am/is/are加现在分词构成。二、用法说明1)表示此时此刻或现阶段正在进行的动作。如:They’rehavingameeting.I’mstudyingataneveningschool.2)表示计划或安排好了的将来动作,常与一个表示将来的时间状语连用。如:MikeiscominghomeonThursday.They’rehavingapartynextweek.注:表示安排将要做的事,人作主语宜用现在进行时,事物作主语,宜用一般现在时。试比较:I’mnotgoingoutthisevening.Theconcertstartsat7:30.3)现在进行时与always,often,forever等连用表示赞扬、厌烦等语气。如:You’realwaysinterruptingme!你老打断我的话!(抱怨)Myfatherisalwayslosinghiscarkeys.我爸老丢车钥匙。(不满)She’salwayshelpingpeople.她老是帮助别人。(赞扬)4)现在进行时在时间和条件状语从句中,代替过去将来时。如:Hepromisedtobuymeacomputerifhegotaraise.注意:像be,think,understand,love,have,own,see,hear,find,belongto等静态动词通常不用于进行时。三.现在进行时的肯定肯定句、否定句、疑问句形式:1)现在进行时的肯定句主语+be+现在分词+……eg.IamwatchingTV.eg.Sheiswashingthedishes.eg.Theyareplayinggames.2)现在进行时的否定句句型主语+相应be动词+not+现在分词+……eg.Heisn'twatchingTV.Iamnotcooking.Wearen'thaveingEnglishcalss.3)现在进行时的一般疑问句句型相应be动词+主语+现在分词+……?eg.Areyoudancing?Ishedrawingapicture?Areyoutalkingwithyourfriend?4)现在进行一般疑问句的答语(1)肯定回答:Yes,主语+相应be动词。(2)否定回答:No,主语+相应be动词+not。eg.Areyoulisteningtothemusic?Yes,Iam./No,Iamnot.IsAuntWangknittingasweater?No,sheisn't.5)现在进行时的特殊疑问句特殊疑问词+相应be动词+主语+doing+…?eg.Whatareyoudoing?Whoissingingasong?Whyaretheycleaningtheirroom?现在进行时特殊疑问句的答语回答特殊疑问时,根据不同的疑问词的情况来决定回答方式。回答what提问时,答语是现在进行时的肯定形式;回答who提问时,只需说明主语是谁,再加相应的be动词即可。eg.Whatishedoing?Heiswritingaletter.Whoisswimminginthelake?Jimis.四.动词的现在分词形式构成方法1.一般动词原形结尾直接在词尾加ing,如:playing,listening,cleaning等等2.重读闭音节单词,末尾以元音字母加一个辅音字母结尾的,双写辅音字母加ing,如:getting,beginning,putting,stopping,sitting,cutting,running,shopping,swimming,setting3.以不发音的字母e结尾,having,coming,writing,taking,making,arriving,living,hoping注意:(一)、把动词变成现在分词形式易出错例:1、Theyareswiming.(swim)2、Jennyisplaiing(play)football.答案:1.swimming2.playing解析:动词变现在分词可有如下口诀:“一添一去y不变”.“一添”指双写规则;“一去”指去掉不发音字母e规则;“y不变”指要与名词变复数区分开。(二).丢掉be动词或忘记把动词变成现在分词1.Look,twochildrenflying.(fly)akiteinthepark.2.LiMingisn’tread(notread)abookinbednow.答案:1.areflying2.isn’treading解析:现在进行时肯定句的结构规律为:“be+现在分词,缺一不可”。这一点必须牢记。(三).对动词或动词词组提问时丢掉doing1.Thestudentsaresingingintheroom.(对划线部分提问)Whatarethestudentsintheroom?答案:Whatarethestudentsdoingintheroom?解析:现在进行时态中对动作提问可记住此句式“What+be+主语+doing+其它?”或简写为“What......doing......”?句式。(四)、现在进行时态的选择疑问句中易忽视or后用现在分词形式例:孩子们在跑还是在跳?Arethechildrenrunningorjump?答案:Arethechildrenrunningorjumping?解析:or连接的是两个并列成分,动词形式须一致。用正确时态完成下列句子:1.What_________you__________(do)?2.I_____________(sing)anEnglishsong.3.What________he____________(mend)?4.He______________(mend)acar.5.______you__________(fly)akite?Yes,_______.6.______she___________(sit)intheboat?7.______you_____________(ask)questions?8.We_______________(play)gamesnow.aredoingamsingingismendingismendingAreflyingIamIssittingAreaskingareplaying9.It’steno’clock.Mymother____________(lie)inbed.10.What___he________(mend)?11.We____________(play)gamesnow.12.What____you____(do)thesedays?13.____he__________(clean)theclassroom?14.Who___________(sing)inthenextroom?15.Thegirl______(like)wearingasweater.Look!She__________(wear)aredsweatertoday.islyingismendingareplayingaredoingIscleaningissinginglikesiswearing1.Look!He_____theirmotherdothehousework.A.ishelpingB.arehelpC.ishelpD.ishelpping2._____aretheboysdoing?Theyaresingingintheroom.A.WhoB.HowC.WhatD.Where3.Don’ttalkhere.Mymother_____.A.issleepingB.aresleepingC.sleepingD.sleep4.–When_____he_____back?–Sorry,Idon’tknow.A.does,comeB.arecomingC.iscomeD.iscoming五.现在进行时主要表示现在或目前正在进行的动作,除此之外,还可以表示将来。现在进行时表将来时常有“意图”“安排”或“打算”的含义。归纳总结如下:1.现在进行时表将来意义使用的动词常为趋向性动词和表示位置转移的动词,常用的有:arrive,come,do,get,go,have,leave,meet,play,return,see,spend,start,stay,wear,work等。例如:①Howareyougoing—byboatorbytrain?②I’mmeetingyouafterclass.2.现在进行时常表最近或较近的将来,句子里常有一个表示未来的时间状语。例如:①They’releavingforHongKongthisafternoon.②WhatareyoudoingnextSunday?3.表将来的现在进行时有时含有“决心”的意思,多用在否定结构中。例如:I’mnotwaitinganylonger.4.现在进行时也可在时间、条件或原因状语从句中表示将来。例如:①Whenyouarepassingmyhouse,pleasedropin.②Iftheyarenotdoingit,whatshouldIdo?③Becausethebrideiscoming,allthepeoplearepleased.5.现在进行时表将来与一般现在时表将来的区别在于:用现在进行时表示将来,其计划性较强,并往往暗示一种意图;而一般现在时表示将来,则其客观性较强,即通常被视为客观事实,多指按时刻表或规定要发生的情况。如果主语是train,concert,programme等表示事物的名词,动词通常用一般现在时表将来而不用进行时。例如:①I’mnotgoingoutfordinnerthisevening.②WhattimedoesthetraintoMianyangleave?⑤一般现在时表示将来时(1)按规定预计要发生的未来动作,仅限于动词come,go,leave,move,start,return,arrive,begin,stay等动词.Theplanetakesoffat10:10.Thatis,it’sleavingintenminutes.(2)用在状语从句中用一般现在时代替将来时。Ifyoudothatagain,I’llhityou.(3)用在Ibet和Ihope后面,常用一般现在时表将来。Ibetyoudon’tgetupbeforetentomorrow.我敢说你明天不到10点是不会起床的。[即学即练]1.—Whatareyougoingtodothisafternoon?—Iamgoingtothecinemawithsomefriends.Thefilm____quiteearly,sowe____tothebook-storeafterthat.(2005重庆卷)A.finished;aregoingB.finished;goC.finishes;aregoingD.finishes;goC2.Ladiesandgentlemen,pleasefastenyourseatbelts.Theplane____.(2006福建卷)A.takesoffB.istakingoffC.hastakenoffD.tookoffB3.Lookatthetimetable.Hurryup!Flight4026_____offat18:20.(2006四川卷)A.takesB.tookC.willbetakenD.hastakenA4.Teenagers____theirhealthbecausetheyplaycomputergamestoomuch.(2008重庆卷)A.havedamagedB.aredamagingC.damagedD.willdamageB5.—Doyouthinkweshouldacceptt
