please don‘t make a noise.为什么用no,l won't .l will be as quiet as a mous.

1.
please don‘t make a noise.祈使句
no,l won't .l will be as quiet as a mous
2.
Tom isn't a boy,is he?反意疑问句
no,he isn't
no,i won't 和no,he isn't的结构成分相同,只是它们后面都省略了部分内容,完整的句子应该是：
no,i won't make any noise；no he isn't a boy；回答否定式的疑问都要根据实际情况回答，而不是依照汉语的习惯是吗？是的，如crystal9285回答的。
