didn't 是 did not 的缩写,在句子中作为助动词使用,后面人称代词的形式如下:
1. 单数人称代词
I didn't 去 + 动词原形
He/She/It didn't 去 + 动词原形
例句:I didn't go to school yesterday.
2. 复数人称代词和你
We/You/They didn't 去 + 动词原形
例句:They didn't finish their homework last night.
3. 名词或名词词组
主语 + didn't 去 + 动词原形
例句: The boy didn't return the book to the library.
4. 需要注意第三人称单数的动词原形要加s
He/She/It didn't go/reads/studies 去 + 动词原形加s
例句:She didn't reads the notice on the wall.
综上所述,didn't 后面人称代词的基本规则是都直接加动词原形,第三人称单数动词原形要加s。正确运用人称代词和动词形式非常重要。
