Question

--Don't forget to return the book in two weeks . --No , I won't . Dont worry about it .

为什么是No, I won't 而不是 Yes, I won't

Answer 1

No, I won't （forget to return the book in two weeks ）
回答否定反义问句要求三个：
1. 不翻译，初学者每翻译成汉语必错。
2. 尊重事实——找关键词，比如这里关键词“forget to return the book ”，当然是No了。
3. 还原答句。No, I won't 还原 No, I won't （forget to return the book in two weeks ）

Answer 2

根据上下文，根据语法原则，前后要一致的No, I won't
