拼写规则（第三人称单数）
| 大多数动词 | 加 -s | play → plays, work → works |
|---|---|---|
| 以 -s、-sh、-ch、-x、-o 结尾 | 加 -es | go → goes, wash → washes |
| 以辅音 + y 结尾 | y → -ies | study → studies, carry → carries |
| have | → has | I have → she has |
常见错误
She go to school every day.
She goes to school every day.
he/she/it 要加 -es/-s
He don't like coffee.
He doesn't like coffee.
he/she/it 要用 doesn't，不是 don't
Does she plays tennis?
Does she play tennis?
does 后面用动词原形（不加 -s）
提示
很多语言的动词形式不会变化，所以容易忘记 -s/-es 规则。小窍门：主语是 he、she、it 时，动词永远加 -s 或 -es。
