英语动词第三人称单数变化规则

一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上, 其规律为：

1、变否定句：含有动词第三人称单数形式的句子变否定句时，要在动词前面加上

doesn't或does no，动词的第三人称单数形式要还原成原形：格式为doesnt/does not +动词原形，如：

He goes to school at six in the morning.变否定句）f He does n't go to school at six in the morning.

2、变一般疑问句：把含有动词第三人称单数形式的变成一般疑问句时，要借用助动词does女口：

She goes home at five every day.

f Does she go home at five every day?

---Yes, she does./No, she does'

3、对划线部分进行提问（变特殊疑问句）：一般格式为Whxxx + 一般疑问句？

She goes home at five every day.对划线部分提问）f When/What time does she go home every day?

She goes home at five every day.对划线部分提问）f Who goes home at five every day?

She goes home at five every day.对戈U线部分提问）

f What does she do at five every day?
