为什么must的否定既有mustn't又有needn't？那need的否定是什么？ must，need，mustn't，needn't的用法？

I am not a little boy! You needn't have told me that much.

比如说：“老师，我必须今天把它交上来吗？Teacher, must I hand it on today ?"
老师肯定说：不，你不必（No, you needn't),而不会说：不，绝对不行！（No, you mustn't)
这是放在语境中，后者肯定讲不通。
而mustn't则用于绝对禁止时。比如：你绝不可以在这里吸烟！（You mustn't smoke here!)
need的否定是needn't，意思是不必，不需要，和我讲的第一种讲的是一致的。
求采纳，不明白楼主请追问。
must否定有三个:
1 can't 不可能 (表示推断）
2 needn't (不毕了，不用了，不需要了）
3 mustn't (禁止，决不能）
need 的否定就是needn't
