动词单三称专项练习在一般现在时中，当主语是第三人称而且是单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。变化规则：1，直接在动词后+S2，以s,ss,o,x,ch,sh结尾的动词+es。例如：guess---guesses，do--does，go---goes，fix---fixes,watch--watches,wash---washes,3，以辅音+y结尾的动词需要把y变i+es。特殊单三称：be动词的单三称是is，have----has哪些主语是第三人称单数还不十分清楚，现归纳总结如下：一、人称代词he,she,it是第三人称单数。如：HelikeswatchingTV.他喜欢看电视。Shehaslunchattwelve.她十二点吃午餐。Itlookslikeacat.它看起来像只猫。（1，请把主语划直线，并说说是第几人称？2，请把谓语动词圈起来并说一说它的动词原形是什么？）二、单个人名、地名或称呼作主语；是第三人称单数。如：①HanMeilookslikehermother.韩梅看起来像她的母亲。②BeijingisinChina.北京在中国。③UncleWangoftenmakescakes.王叔叔经常做蛋糕。三、单数可数名词或this/that/the+单数可数名词作主语时，是第三人称单数。如：①Thisbookisyours.这本书是你的。②Thatcarisred.那辆小汽车是红色的。③ThecatisLucy's.这只猫是露茜的。④Thatcathastwocuteeyes.那只猫有两只可爱的眼睛。四、不定代词someone,somebody,nobody,everything,something等及指示代词this,that作主语时，是第三人称单数。如：①Everyoneishere.大家到齐了。Nobodygoesthere。没有人去那里。②Thereissomethingwrongwiththewatch.这块手表有毛病。③Thispenlookslikeasnake.这支钢笔看起来像条蛇。④Thatisaneraser.那是一块橡皮擦。五、不可数名词作主语时为第三人称单数。如：①Themilkisintheglass.牛奶在玻璃杯里。②Thebreadisverysmall.那面包很小。六、当数字或字母作主语时，看作第三人称单数。如：①6isaluckynumber.6是个吉利数字。②Iisaletter.I是个字母。动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。提示：1，问句中出现does或者did，后面要用动词原形。2，主语是第三人称单数而且后面的动词是普通动词的否定陈述句，要用doesn’t来否定。单三称检测题：I.写出下列动词的相应形式：1.第三人称单数：wash_______match_______guess______study______finish_________go________snow______carry_________look______like______see______fix______II.用所给动词的适当形式填空：1.He______not_______(see)mecomein,forhe___________(read)somethingwithgreatinterest.2.we________(wait)forourteacher,alittleboy________(run)uptous.3.Don’tmakeanoise.Grandpa__________(sleep).4.It’ssevennow,Tom’sfamily__________(watch)TV.5.It________(take)metwohourstofinishmyhomeworkeveryday.6.What______yourmother_______(do)ateightyesterdayevening?She_______(wash)clothes.12.There________(be)afootballmatchonTVthisevening.14.Who_______(dance)thebestinyourclass?15.Willyoucomeifhe_____________(notcome)?16.Theteachertoldustheearth__________(move)roundthesun.单三称检测I.写出第三人称单数：wash_________match_______guess______study______finish_________go________snow______carry_________II.用所给动词的适当形式填空：1.He________TVeveryevening.(watch)2.Wealways________toschoolonfoot.(go)3.Tom,withhisclassmates,often______footballafterschool.(play)4.Yourshoes_______underthebed.(be)5.______hereand______byme.(come,stand)6.Hisuncleusually_________toworkbybus.(go)7.Ialways______upatsixinthemorning.(get)8.John________likehisfather.(look)III.完成句子1．该吃晚饭了。It’stimeto________________.2．你想来点儿面包吗?Wwouldyou________some________?3．安娜太小，还不能上学。Annis________young________gotoschool.4．约翰跑得和我一样快。John____asfastasme.5．布莱克太太经常在英语上帮助我们。Mrs.blackoften________us________ourEnglish.请看下面两组句子，注意区分他们的共同点和不同点。Igotoschooleveryday.Idon'tgotoschooleveryday.Hegoestoschooleveryday.Hedoesn'tgotoschooleveryday.Doyougotoschooleveryday?Yes,Ido.(No,Idon't)Yes,hedoes.(No,hedoesn't)Doeshegotoschooleveryday?注：1）第三人称单数用了does后面就不用动词的s形式了,而用动词原形.2）变为疑问句,要在句首加dodoes;变为否定句,要在动词前面加donot,doesnot,可以简写为don't.doesn’t单三称检测一、把下列句子改成一般疑问句并做肯定、否定回答。例子：1．Iusuallygetupatsixo’clock.Doyouusuallygetupatsix?Yes,Ido./No,Idon’t.2.Weusuallywritee-mailsonSaturdayevening.3.Theyhavethesamehobby.4.SuhaiandSuyanglikelisteningtomusicafterschool.5.HelenusuallywatchesTVintheevening.二、用词的适当形式填空。1.Whattime_________hisfather_________(do)thework?2.He_________(get)upatfiveo’clock.3.__________you_________(brush)yourteetheverymorning.4.What________(do)heusually________(do)afterschool?5.Tom________(study)English,Chinese,Maths,ScienceandArtatschool.6.Kittysometimes__________(go)totheparkwithhissister.7.Ateightatnight,she__________(watch)TVwithherparents.8.________Mike________(read)Englisheveryday?9.Howmanylessons________yourclassmates______(have)onMonday?10.Weoften___________(play)footballintheplayground.三．选择()1._____youhaveabook?A.DoB.AreC.IsD.Have()2.They_________onafarm.A.workingB.isworkC.workD.isworked()3.DoesPeterliketowatchTV?__________.A.Yes,helikeB.No,hedoesn’tC.Yes,he’dlikeD.No,helikes()4.Shedoesn’t__________herhomeworkintheafternoon.A.doingB.todoC.doesD.do()5.How______Mr.Brown_________toAmerica?A.do,goB.is,goC.does,goD.does,goes()6.Where’smycamera?I_______it.A.amnotfindingB.amnotseeingC.can’tfindD.can’tlookat()7.How___hegotowork?He____toworkbybike.A.does;goB.do;goesC.do;goD.does;goes()8.___youusuallylateforschool?No,___.A.Do;IamB.Does;notC.Are;I’mnotD.Are;Iaren’t()9._____she_____homeatsixeveryday?A.Is,leaveB.Does,leaveC.Is,leavesD.Does,left()10.Mr.Yang______Englishthisterm.A.teachesourB.teachesusC.teachsusD.teachour四、填空.1.Lethim_____(play)basketball.2.Everyone_____(know)whathereallylike.3.Tosegirls____(be)mysister.4.Thatgirl_____(call)meevetySunday.5.How___(do)she_____(spell)theword?五、否定句:在动词前+doesn't或don't.1.She__________(do)herhomeworkeveryday.2.He__________(live)inHuanggang.3.He__________(need)apairpfshoes.4.Danny__________(see)theappletree?5.She__________(come)fromAmerica.6.Thegirl__________(look)outofthewindowandseesmanybiedsinthesky.7.Jennyrunshomeand__________(sit)onthechair.六、一般疑问句:1._____thedesk_____(have)fourlegs?Yes,itdoes.2._____she____(do)herhomeworkeveryday?Yes,shedoes.3._____he_____(live)inHuangga
