动词单三称专项练习在一般现在时中，当主语是第三人称而且是单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。变化规则：1， 直接在动词后+S2， 以s,ss,o,x,ch,sh结尾的动词+es。例如：guess-guesses，do-does，go-goes， fix-fixes, watch-watches, wash-washes,3，以辅音+y结尾的动词需要把y变i +es。特殊单三称：be 动词的单三称是is，have-has哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、 人称代词he, she, it是第三人称单数。如： He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。 （1，请把主语划直线，并说说是第几人称？2，请把谓语动词圈起来并说一说它的动词原形是什么？）二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei looks like her mother. 韩梅看起来像她的母亲。 Beijing is in China. 北京在中国。 Uncle Wang often makes cakes. 王叔叔经常做蛋糕。 三、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。如： This book is yours. 这本书是你的。 That car is red. 那辆小汽车是红色的。 The cat is Lucys. 这只猫是露茜的。 That cat has two cute eyes. 那只猫有两只可爱的眼睛。四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。如： Everyone is here. 大家到齐了。 Nobody goes there。 没有人去那里。There is something wrong with the watch. 这块手表有毛病。 This pen looks like a snake. 这支钢笔看起来像条蛇。 That is an eraser. 那是一块橡皮擦。 五、不可数名词作主语时为第三人称单数。如： The milk is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。 I is a letter. I是个字母。 动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。提示：1， 问句中出现does或者did，后面要用动词原形。2， 主语是第三人称单数而且后面的动词是普通动词的否定陈述句，要用doesnt 来否定。单三称检测题： I.写出下列动词的相应形式： 1. 第三人称单数： wash_ match _guess_ study_ finish_ go_ snow_ carry_ look_ like _ see_ fix_II. 用所给动词的适当形式填空： 1.
