一般现在时和现在进行时是初一阶段所学的两种重要时态，它们的不同之处有以下几点：1)基本用不同；2)谓语动词的形式不同；3)时间状语不同；4)有不同的特殊用法。一、基本用法不同【1】一般现在时用来表示习惯性的动作或状态。如：Shegoestoschoolbybikeeveryday.她每天骑自行车去上学。【2】现在进行时用来表示现在(说话的瞬间)正在发生或进行的动作或者用来表示现阶段正在进行或存在的状态。如：Look!Sheisreadingunderthetree.瞧！她正在树下看书。二、谓语动词的形式不同【1】一般现在时的谓语动词：1)be动词用am/is/are这三种形式；2)实义动词用动词原形或第三人称单数形式(根据主语数的变化而变化)。【2】现在进行时谓语动词的形式为：am/is/are+动词-ing形式。如：Wegotoschoolatseveninthemorning.我们早晨七点钟上学。IamreadingEnglishnow.我现在正在读英语。三、时间状语不同【1】一般现在时常与often,sometimes,always,usually等频率副词及onceaweek/day等频率短语连用，还与everymorning/day/week...,onWednesday,inthemorning/afternoon/evening等时间状语连用。【2】现在进行时常与now,thesedays,theseweeks等时间状语连用。句首有Look!/Listen!等提示语时，后面的句子中动词一般用现在进行时。四、特殊用法1.一般现在时的特殊用法：表示客观真理、自然现象往往要用一般现在时表示。如：Themoongoesroundtheearth.月亮绕着地球转。2.现在进行时的特殊用法：现在进行时与always连用时，往往含有赞扬、厌恶、责备等感情色彩。如：Heisalwaysworkinghard.他总是非常努力地工作。(表示赞扬)come,go,begin,start,leave等动词常用现在进行时表示将要发生的动作。如：I'mcoming.我就来。一、选择题练习1.Who_____overtherenow?A.singingB.aresingC.issingingD.sing2.It’seighto’clock.Thestudents_____anEnglishclass.A.haveB.havingC.ishavingD.arehaving3.Listen!Thebaby_____inthenextroom.A.cryingB.criedC.iscryingD.cries4.Look!Thetwins_____newsweaters.A.arewearingB.wearingC.arewearD.iswearing5.Don’ttalkhere.Grandparents_____.A.issleepingB.aresleepingC.sleepingD.sleep6.Tomisaworker.He_____inafactory.Hissisters_____inahospital.A.work/workB.works/workC.work/works7.Who_____Englishbestinyourclass?A.speakB.speaksC.speaking8.MrsRead_____thewindowseveryday.A.iscleaningB.cleanC.cleans9.We_____musicandoften_____tomusic.A.like/listenB.likes/listensC.like/arelistening10.She_____upatsixinthemorning.A.getB.getsC.getting11.OnSundayhesometimes_____hisclothesandsometimes_____someshopping.A.wash/doB.iswashing/isdoingC.washes/does12.Thetwinsusually_____milkandbreadforbreakfast,butJim_____somecoffeeforit.A.have/haveB.have/hasC.has/have二、填空：1.Myfatheralways__________(come)backfromworkverylate.2.Theteacherisbusy.He__________(sleep)sixhoursaday.3.Listen!Joan__________(sing)intheclassroom.Sheoften__________(sing)there.4.__________yourbrother__________(know)Japanese?5.Where__________you__________(have)luncheveryday?6.Thegirl__________(like)wearingaskirt.Look!She__________(wear)aredskirttoday.三、写出下列动词的现在分词形式1.work___________sing__________play__________study__________2.dance__________have__________write__________take__________3.run__________sit__________shop__________swim__________4.lie__________四、写出下列动词的第三人称单数形式1.work__________read__________clean__________write__________2.teach__________wash__________guess__________watch__________3.go__________do___________photo__________4.study__________fly__________cry__________play__________5.have__________五、根据中文意思完成句子1、学生们在干什么？有一些在打电话，另一些躺在沙滩上。__________thestudents_____?Some__________onthephone,_______________onthebeach.2、“格林先生在看电视吗？”“不，他在打扫房间。”“_____MrGreen_____TV?”“_____,He__________thehouse.”3、魏芳不是在读书，她在写信。WeiFang__________abook.She__________aletter.4、我正在通过收音机学(learn)英语。I__________Englishontheradio.5、这个老人每天早上六点钟起床。Theoldman__________atsixo’clockinthemorningeveryday.6、你从哪里来？Where_____youfrom?或Where_____you_____from?我从美国来。I_____fromAmerica.或I_____fromAmerica.
