一般现在时动词第三人称单数变化规则

一般现在时、动词第三人称单数变化规则1一、概述一般现在时的概念和用法：（1）表示现阶段经常、反复、习惯性的动作;（2）表示目前的状况；（3）表示自然界的客观真理。二、一般现在时的结构时态的结构指的是动词的变化形式。一般现在时间有两种结构，一种是动词原形，用于主语为非第三人称时的情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。Eg1.Weoftengetupearlyinthemorning.Eg2.Myfatheroftengetsupearlyinthemorning.三、谈谈“主语为三单，其后动词s添”在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单，其后动词s添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，如he,she,it,myfather,mymother,mysister,ourEnglishteacher,Tom,Mike,LiuJia,China,mybook,etc.Eg3.Hesometimesgoestoschoolbybike.Eg4.Myfatherworksinthehospitalasadoctor.四、一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律为：（与名词变成复数的变法大致相同。）规则原形第三人称单数形式1、一般情况下，直接在动词词尾+sgettakeplaygetstakesplays2、以s,x,sh,ch,o结尾的动词，在词尾+esguessfixfinishteachgo和doguessesfixesfinishesteachesgoes和does3、以辅音字母+y结尾的动词，先把y变为i，再加esstudytryflycarryworrystudiestriesfliescarriesworries4、不规则动词（特殊情况）havebehasis五、一般现在时的句子转换（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例：①陈述句：Sheisastudent.一般疑问句→Issheastudent?否定句→Sheisnotastudent.一般现在时、动词第三人称单数变化规则2②陈述句：Icanswim.一般疑问句→Canyouswim否定句→Icannotswim.（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do(you,以及复数),does（单数she,he,it）变成一般疑问句；在主语后谓语动词前加助动词don’t（I,you,以及复数),doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。例：①陈述句：Wegetupat7:00everymorning.一般疑问句→Doyougetupat7:00everymorning?否定句→Wedon’tgetupat7:00everymorning.②陈述句：Shehasalittlebrother.一般疑问句→Doesshehavealittlebrother?否定句→Shedoesn’thavealittlebrother.哪些主语是第三人称单数？1、人称代词he,she,it；如：HelikeswatchingTV.他喜欢看电视。Shehaslunchattwelve.她十二点吃午餐。Itlookslikeacat.它看起来像只猫。2、单个人名、地名或称呼作主语；是第三人称单数。如：HanMeilookslikehermother.韩梅看起来像她的母亲。BeijingisinChina.北京在中国。UncleWangoftenmakescakes.王叔叔经常做蛋糕。3、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；Ahorseisausefulanimal.马是有用的动物。Thisbookisyours.这本书是你的。Thatcarisred.那辆小汽车是红色的。ThecatisLucy's.只猫是露茜的。4、不可数名词作主语时为第三人称单数。如：Themilkisintheglass.牛奶在玻璃杯里。Thebreadisverysmall.那面包很小。Thewaterisverycold.那些水很凉。1、写出下列动词的第三人称单数。drink________go_______stay________make________look_________have_______pass_______carry_______come________watch________plant_______fly________study_______brush________teach________catch_________wash___________do________like________say_______learn___________eat___________read___________sing___________buy__________study_______come__________plant(种植)______2、用括号内动词的适当形式填空。1.Heoften________(have)dinnerathome.2.We_____________(notwatch)TVonMonday.3.Nick___________(notgo)tothezooonSunday.一般现在时、动词第三人称单数变化规则34.________they__________(like)theWorldCup?5.What_________theyoften_________(do)onSaturdays?6._________yourparents_________(read)newspaperseveryday?7.There________(be)somewaterinthebottle.8.Myaunt_______(look)afterherbabycarefully.9.Thechildoften_______(watch)TVintheevening.10.Mike’ssister________(cook)nicefood.I_______(like)eatingitverymuch.11._______(do)yourbrother_______(watch)TVintheevening?No,he_______(not).12.Weoften___________(play)intheplayground.13.He_________(get)upatsixo’clock.14.__________you_________(brush)yourteetheverymorning.15.What________(do)heusually______(do)afterschool?16.Danny_______(study)English,Chinese,Maths,ScienceandArtatschool.17.Mikesometimes__________(go)totheparkwithhissister.18.Ateightatnight,sheoften__________(watch)TVwithhisparents.19.________Mike________(read)Englisheveryday?20.Howmanylessons_________yourclassmate________(have)onMonday?21.Whattime_________hismother_________(do)thehousework?1.We_____________(go)toschoolonfooteveryday.2.They______________(nothave)anylessonsonSundays.3.She_____________(brush)herteethtwiceaday.4.Thesestudents____________(benot)goodatboating.5.WeiHuaalways____________(carry)waterforhisgrandpaonSundays.6.___________Kate____________(like)makingfriends?7.Thelazyboy______________(notdo)hishomeworkintheevening.8.Howmanyclasses_________you__________(have)everyday?9.Who__________thebaby___________(look)like?10.Hecan___________(teach)usEnlgishwell.11.Heoften________(have)dinnerathome.12.DanielandTommy_______(be)inClassOne.13.Nick_________(notgo)tothezooonSunday.14.What_______theyoften_______(do)onSaturdays?15._______yourparents_______(read)newspaperseveryday?16.Thegirl____________(teach)usEnglishonSundays.17.SheandI________(take)awalktogethereveryevening.18.There________(be)somewaterinthebottle.19.They_______(have)thesamehobby.20.Myaunt__________(look)afterherbabycarefully.21.Youalways_______(do)yourhomeworkwell.22.I_______(be)ill.I’mstayinginbed.23.She_______(go)toschoolfromMondaytoFriday.24.Thechildoften____________(watch)TVintheevening.25.-Whatday_______(be)ittoday?－It’sSaturday.26.He_________(get)upatsixo'clock.一般现在时、动词第三人称单数变化规则4()1.I________toschoolat7:00inthemorning.A.goB.goingC.goes()2.They_______bookseverydayinthelibrary.A.readsB.readC.reading()3.Themonkey________eatingbananasverymuch.A.likeB.likesC.liking()4.Myfather________toreadnewspaperaftersuppereveryday.A.likeB.likesC.liking()5.IlikewatchingTV,butmymother_________likeit.A.don’tB.doesn’tC.does()6.____________yourfatherdrinkmilkeveryday?A.doB.areC.does()7.Wewillgoshoppingifit____tomorrow.A.don'trainB.didn'trainC.doesn'trainD.isn'train()8.Hesaidthesun____intheeastand____inthewes
