词第三人称单数形式讲.ppt
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:I we 第二人称:you 第三人称:he、she、it、they和人名类(如:Peter、Jane、my father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:I watch TV every day.如果主语是三单,动词要变化:He watches TV every day.She watches TV every day.Jane watches TV every day.,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-plays 2、以s,x,sh,ch,o 结尾的加es,如 wash-washes,go-goes,do-does,watch-watches 3、以辅音字母+y 结尾的,改y 为i 再加es,如 study-studies,try-tries 4、特殊变化,如 have-has,四、does和doesnt 在句子中的用法 否定句:主语+dont/doesnt+动词原形+(其他)。如:I dont watch TV.我不看电视。当主语为第三人称单数时,要用doesnt 构成否定句。如:He doesnt watch TV.他不看电视。注意doesnt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:Do you watch TV?Yes,I do./No,I dont.当主语为第三人称单数时,要用does 构成一般疑问句。如:Does she watch TV?Yes,she does./No,she doesnt.,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.He often _(have)dinner at home.2.We _(not watch)TV on Monday.3.Nick _(not go)to the zoo on Sunday.4._ they _(like)the World Cup?5._ your parents _(read)newspapers every day?6.The girl _(teach)us English on Sundays.7.She and I _(take)a walk together every evening.8.Mike _(like)cooking.9.They _(have)the same hobby.10.My aunt _(look)after her baby carefully.,C、选出正确的答案:1.She(like/likes)to play football.2.He(like/likes)drinking milk.3.I(like/likes)to watch TV.4.We(like/likes)to play badminton.5.They(like/likes)to sing songs.6.She(read/reads)books every day.7.He(play/plays)computer games every day.8.It(listen/listens)to the radio every day.9.Linda(draw/draws)pictures every day.10.Jane and Linda(play/plays)football every day.,
