一 小学英语动词的单三形式讲解
大家都知道，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：
  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。
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：

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。
六、当数字或字母作主语时，看作第三人称单数。如：
   ①"6" is a lucky number. "6"是个吉利数字。
   ②"I" is a letter. "I"是个字母。
