动词 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：
① He likes watching TV. 他喜欢看电视。 ② She has lunch at twelve. 她十二点吃午餐。 ③ It looks like a cat. 它看起来像只猫。
。如：
① Han Mei looks like her mother. 韩梅看起来像她的母亲。 ② Beijing is in China. 北京在中国。
③ Uncle Wang often makes cakes. 王叔叔经常做蛋糕。 如：
① A horse is a useful animal. 马是有用的动物。 ② This book is yours. 这本书是你的。 ③ That car is red. 那辆小汽车是红色的。 ④ The cat is Lucy's. 这只猫是露茜的。
等及指示代词
二、单个人名、地名或称呼作主语；是第三人称单数
三、单数可数名词或 \ 单数可数名词 \作主语时，是第三人称单数 。
四、不定代词 someone, somebody, nobody, everything, something
this, that 作主语时，是第三人称单数 ① Everyone is here. 大家到齐了。
② There is something wrong with the watch. 这块手表有毛病。 ③ This is a pen. 这是一支钢笔。 ④ That is an eraser. 那是一块橡皮擦。
。如：
五、不可数名词作主语时为第三人称单数。如：
① The milk is in the glass. 牛奶在玻璃杯里。 ② The bread is very small. 那面包很小。
。如：
① \是个吉利数字。 ② \是个字母。
六、当数字或字母作主语时，看作第三人称单数

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”：
① stop－ stops [s] ; make－ makes [s] ② read－ reads [z] ; play －plays [z] 2、以辅音字母加 “ y结”尾的，要先将 “ i，”然后在加 “ es读”[iz] 如：
“ y变”为
fly － flies [z] ； carry －carries [z] study－ studies [z]; worry － worries 3、以 “ s, x, ch, sh结尾的”，在词尾加 teach－ teaches [iz]; watch － watches [iz] 4、以 “ o结”尾的动词，加 go－ goes [z] do －does [z] 5、不规则变化： - have － has
- Be － am（第一人称单数）is
“ es，”发音为 [iz] 如：
“ es，” 如：
（第三人称单数）
are （第二人称和所有复数）
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 [sei]－ says [sez]
3、以不发音字母 “ e结”尾的开音节词，如果尾音是
发”
[s]， [z] 时，加 “ s后”字母 “ e
音，与所加 “s一”起读做 [iz] 。 如： close－closes [iz]
