第三人称单数用法讲解及练习题

动词第三人称单数形式讲解一、什么是第三人称单数？人称可分为三类：第一人称、第二人称和第三人称第一人称：Iwe第二人称：you第三人称：he、she、it、they和人名类（如：Peter、Jane、myfather等）结合以上知识，第三人称单数就是he、she、it和单个的某人，也包括单个的动物、东西等。二、动词为什么要变成相应的三单形式？在一般现在时中，跟在第三人称单数后面的动词也要变成相应的三单形式，例如：IwatchTVeveryday.如果主语是三单，动词要变化：HewatchesTVeveryday.ShewatchesTVeveryday.JanewatchesTVeveryday.三、动词三单的变化规则1、一般情况下直接加s，如speak-speaks,like-likes,play-plays2、以s,x,sh,ch,o结尾的加es，如wash-washes,go-goes,do-does,watch-watches3、以辅音字母+y结尾的，改y为i再加es，如study-studies，try-tries4、特殊变化，如have-has四、does和doesn’t在句子中的用法否定句：主语+don’t/doesn’t+动词原形+（其他）。如：Idon’twatchTV.我不看电视。当主语为第三人称单数时，要用doesn’t构成否定句。如：Hedoesn’twatchTV.他不看电视。注意doesn’t后面用动词原形watch，而不是watches一般疑问句：Do/Does+主语+动词原形+（其他）。如：DoyouwatchTV?Yes,Ido./No,Idon’t.当主语为第三人称单数时，要用does构成一般疑问句。如：DoesshewatchTV?Yes,shedoes./No,shedoesn’t.特殊疑问句：疑问词+一般疑问句。如：Howdoyougotoschool?Bybike.HowdoesJanegotoschool?Bybus.五、动词第三人称单数形式的练习A、写出下列动词的第三人称单数。drink________go_______stay________make________have_______pass_______carrycome________plant_______fly________study_______brush________look_________teach_______watch______B、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.4.______they________(like)theWorldCup?5._______yourparents_______(read)newspaperseveryday?6.Thegirl_______(teach)usEnglishonSundays.7.SheandI________(take)awalktogethereveryevening.8.Mike_______(like)cooking.9.They_______(have)thesamehobby.10.Myaunt_______(look)afterherbabycarefully.11.Youalways_______(do)yourhomeworkwell.12.She_______(go)toschoolfromMondaytoFriday.13.LiuTao_______(do)notlikePE.14.Thechildoften_______(watch)TVintheevening.15.SuHaiandSuYang_______(have)eightlessonsthisterm.16.Mike’ssister________(cook)nicefood.I_______(like)eatingitverymuch.17._______(do)yourfather_______(watch)TVintheevening?No,he_______(not).18.Tomusually_______(play)footballafterschool19.He_______(live)inasmalltownnearNanjing.20.I______(go)toschoolbybus,andhe______(go)toschoolbybike.C、选出正确的答案：1.She(like/likes)toplayfootball.2.He(like/likes)drinkingmilk.3.I(like/likes)towatchTV.4.We(like/likes)toplaybadminton.5.They(like/likes)tosingsongs.6.She(read/reads)bookseveryday.7.He(play/plays)computergameseveryday.8.It(listen/listens)totheradioeveryday.9.Linda(draw/draws)pictureseveryday.10.JaneandLinda(play/plays)footballeveryday.D、把下列句子变为否定句：1.Shedrawspictureseveryday.2.Welikeplayingfootball.3Lindaswimseveryday.4Theylikeplayinggames.5.Myfatherreadsnewspaperintheevening.6.Helikesdrawingpictures.____________________________________________________________E、把下列句子变为疑问句，并做肯定回答。1.Myfathercanrideahorse.2.shedoesherhomeworkathome3.MissGreenlikesdancingverymuch.4.wecleantheclassroom.___________________________________________________________5.Mymothercooksthemeals.6.Icleanthebedroomeveryday.___________________________________________________________7.Theyreadbooksintheclassroom.8.Thechildrensinginthemusicroom.
