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。
Grandma gives Daming a present.
Sam has lunch.
It copies the other snake!
Daming watches TV.

1.一般情况下，直接在动词后+s ，
collect →collects come →comes play →plays think →thinks
Hale Waihona Puke sound → sounds drop →drops say → says like →likes
.
2.以s, sh, ch, x, o 结尾的动词，在词尾+ es
.
不规则变化动词 have → has do → does
