小学英语总复习（二）语法一般现在时中第三人称单数作主语时谓语动词的使用小学英语总复习（二）语法六、一般现在时中第三人称单数作主语时谓语动词的使用基础知识英语的动词作谓语时,它的形式会随着时态\人称和数等的变化而变化.这里我们说的是在一般现在时句子中,第三人称单数作主语时谓语动词的变化首先我们必需搞清楚两个概念:一般现在时和第三人称单数。一般现在时:英语有过去时、现在时、将来时等时态。一般现在时表示的是经常出现、重复发生的情况.always,usually,often,sometimes,seldom,never,everyday,everyweek等。第三人称单数:在说人称代词时,我们知道人称代词有人称和数之分,人们称自己的"我、我们"是第一人称,称听话者的此之外的其它人或东西,我们一律称谓"他/她/它(们)"这就是第三人称,第三人称单数的人称代词有he,she和it。在一般现在时的句子中,当主语是除第三人称以外的其它人称时,谓语动词一律用原形.当主语是第三人称单数时化,其规则是:1.一般情况下,在原动词的后面加-s构成。如:get-gets等。Igetupat6:00everyday.-Hegetsupat6:00everyday.2.以o,sh,ch结尾的动词,在词尾加-es构成.如:do-does;go-goes;wash-washes;watch-watches等。IoftenwatchTVintheevening.-MymotheroftenwatchesTVintheevening.3.以辅音字母加y结尾的动词,将y改成i后再加-es.如:study-studies等。Westudyhardatschool.-Johnstudieshardatschool.注意:在句子中,如果使用了助动词does,don't,will,won't,can,would,wouldn't,must,mustn't等,尽管主语是第三人称单数化。如:Hedoesn'twanttogoshopping.Canhemovethestone?Mikewon'tcometoschooltomorrow.实战练习：一、写出下例动词在第三人称单数作主语时的正确形式1、make________2、do________3、come________4、go________5、buy________6、watch________7、catch________8、say________9、studt________10、wash________11、move________12、play________二、单项选择()1、I____toschoolontimeeveryday.A.goB.goesC.going()2、Weusually____upquiteearly.A.getB.getsC.getting()3、You____fivegoldfish,Iknow.A.HaveB.hasC.having()4、They____climbingmountains.A.likeB.likesC.liking()5、He____someinterestingstory-books.A.haveB.hasC.having()6、She____exerciseeverydayafterschool.A.takeB.takesC.taking()7、Ihaveacat.It____aloteveryday.A.sleepB.sleepsC.sleeping()8、TomandJack____thedishesfortheirmomeveryday.A.doB.doesC.doing()9、Jimmy____hisbedroomeveryweek.A.cleanB.cleansC.cleaning()10、____heoftensweepthefloorathome?A.DoB.DoesC.Doing()11、____Mike'ssisterwatchTVeveryevening?A.DoB.DoesC.Doing()12、Myfathernever_____hisclothes.A.WashB.washsC.washes()13、Mybrother____hard.A.studyB.studysC.studies()14、Benoften____footballforonehourafterschool.A.playB.playsC.plaies()15、MyclassmateLindan____sheis9.A.sayB.saysC.saies()16、CanLindai____theoldman?A.helpB.helpsC.helping()17、Joedoesn't____anymoneynow.A.haveB.hasC.having()18、Whatdoesyourmother____?A.doB.doesC.doing()19、Tom'sEnglishteacher____himquestionseveryoften.A.askB.asksC.asking()20、Shewill____theflowerslater.A.waterB.watersC.watering三、根据首字母提示补全单词,使短文完整。Gogousually(1)g___upbefore7:00.Afterhegetsuphe(2)t____someexercisefor15minutes.He(3)g____toschoolatabout7:45.He(4)h____sixclassesveeryday,fourinthemorning,twointheafternoon.Thefirstclass(5)b____at8:20.He(6)e____hislunchintheschool.Afterhislunch,hesometimes(7)r____books,sometimeshasanap.Afterschoolintheafternoon,heoften(8)p____footballwithhisfriendsforanhour.He(9)g____homeat5:30.Heeatsdinnerat7:00.Beforeeatingdinner,heusually(10)w___hishands.Intheevening,he(11)d____hishomework.Afterthat,He(12)w____TVforanhour.Andthenhe(13)g____tobedatabout10:00.四、用所给动词的适当形式填空。1.____(do)May____(come)hereeveryday?2.____(do)yourparentsoften____(give)youmoney?3.He____(want)togotoBeijingnextFriday.4.Jim____(brush)histeethatabout7inthemorning.5.TonyandIusually____(help)ourteachers.6.Hissister____(love)singingsongs.7.Thecleaner____(empty)thetrashbineverymorning.8.Jeandoesn't____(play)football.Sheplaysbasketball.9.Mydadcan____(make)atoycarforme.10.Peter'sparents____(take)exercisefor2hourseverySundaymorning.(未完,待续,下一篇语法七、现在进行时
