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 not，动词的第三人称单数形式要还原成原形：格式为doesn’t/does not + 动词原形，如：

He goes to school at six in the morning. (变否定句) →He doesn'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，如：

She goes home at five every day. →Does she go home at five every day? --- Yes, she does./No, she doesn’t. 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) →When/What time does she go home every day?

She goes home at five every day. (对划线部分提问)


→Who goes home at five every day?

She goes home at five every day. (对划线部分提问) →What does she do at five every day?
