1、第三人称单数问题在一般现在时中，当主语是第三人称单数时，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。但有些同学们对于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。 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
2、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： A horse is a useful animal. 马是有用的动物。 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。 四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第
3、三人称单数。如： Everyone is here. 大家到齐了。 There is something wrong with the watch. 这块手表有毛病。 This is a pen. 这是一支钢笔。 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。
4、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。1、大多数动词在词尾加“S”如：stopstops s ; makemakes sreadreads z ; playplays z2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读iz 如：flyflies z； carrycarries zstudystudies z; worryworries3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为iz 如：teachteaches iz; watchwatches iz4、以“o”结尾的动词，加“es”， 如：gogoes z d
5、odoes z注：下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。 如：1、do du:does dz 2、say seisays sez以不发音字母“e”结尾的开音节词，如果尾音是s，z时，加“s”后字母“e”发音，与所加“s”一起读做iz。 如：closecloses izI. 写出第三人称单数：wash_ match _guess_ study_ finish_ go_ snow_ carry_II. 用所给动词的适当形式填空：1.

8、to school every day?Yes, I do. (No, I dont)Yes, he does. (No, he doesnt)Does he go to school every day?注：1）第三人称单数用了 does 后面就不用动词的s形式了,而用动词原形.2）变为疑问句,要在句首加do does ; 变为否定句, 要在动词前面加do not ,does not, 可以简写为 dont.doesnt课堂练习一、把下列句子改成一般疑问句并做肯定、否定回答。1I usually get up at six oclock.2.
