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.A、写出下列动词的第三人称单数。drink________go_______stay________make________have_______pass_______carry________come________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.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.
