"她每天看电视"写成 She watch TV every day，漏了 es。动词第三人称单数变化，规则其实和名词复数几乎一样。
规则一：一般直接加 s
- I like → He likes
- I play → She plays
- I run → It runs
规则二：s / x / ch / sh / o 结尾加 es
- watch → watches
- teach → teaches
- wash → washes
- go → goes
- do → does
读音多一个 /ɪz/ 或 /z/，别漏。
规则三：辅音 + y，y 变 i 加 es
- study → studies
- fly → flies
- cry → cries
- enjoy → enjoys（前面是元音 o，直接加 s）
最容易错的三个
- have → has（不是 haves）
- be → is
- do → does
一句对照
- I go to school by bus.
- He goes to school by bus.
- She doesn't like apples.（doesn't 后面动词回原形）
口诀：三单规则名复数，s x ch sh o 加 es；辅音 y 变 ies，have has 单独记。
