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 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.
