一般简单时的小笔记：第三人称单数
-
在第三人称单数时，动词一律以 s 结尾：
he wants, she needs, he gives, she thinks. -
否定句和疑问句要用 does（= 助动词 do 的第三人称动词变化） 不带 to 的不定词。
he wants ice cream. does he want strawberry? he does not want vanilla. -
以 y 结尾的动词：第三人称动词要将 y 改为 ies：
fly --> flies, cry --> cries
例外情况：字尾 y 前面有母音：
play --> plays, pray --> prays -
当动词原型字尾是 ss、x、sh、ch 时，就在字尾加 es：
he passes, she catches, he fixes, it pushes
举例
- he goes to school every morning.
- she understands english.
- it mixes the sand and the water.
- he tries very hard.
- she enjoys playing the piano.
