don't need 和 needn't 有什么区别？谢谢！

needn't
need在这里是情态动词,不必要.做MUST的否定句时用.

例如: MUST YOU GO WITH HIM?
NO, I NEED NOT.

翻译: 你必须跟他去吗?
不，我不必.

don't need
need 在这里是实意动词,不需要

例如: DO YOU NEED A PEN?
NO. I DON'T NEED. I HAVE A BALLPEN WITH ME.

翻译: 你需要钢笔吗?
不，不需要. 我身上有只圆珠笔.

needn't中need是情态动词,后面接动词原型.
You needn't do that.
don't need后面要接不定式.
You don't need to do that.

一样的意思啊，只是后面的是缩写

need是不需要，作动词，而needn't是不允许，做情态动词

没有区别

Don't need no... 找一首英文歌曲:Don't Need This needn't 和 don't need 的区别 maybe I don\'t need to exist 翻译don't need taking without saying anyting You don't need to be.的语法问题。 you don't need to be afraid什么意思？ You need some help,don't you? 为什么用don't you 为什么老说no need呢。什么时候用don't need 呢 don't need 和need有什么区别？为什么有时候用的不一样？
