need有两种用法,一种是情态动词,一种是谓语动词.当情态动词时,否定为needn't,搭配为：need do 解释为“必要.”
当谓语动词时,否定为don't need,搭配为：dont need to do 或dont need sth解释为 需要需求
i neednt finish the work today 说明我今天不必把工作做完,没有必要性
neednt have done 是不必要做但是已经做了
例如 i neednt have hurried 我当时不必那么匆忙
第三次了.
dont need 中的need 是需要,需求,意为缺乏所以需要,而不是必须要,必要
例如that dog needs/doesnt need a bath 那只狗需要/不需要洗个澡
do you need any help? 你需要帮助么
这里的need是做动词使用而neednet是情态动词

这句话中need是作为行为动词来使用的，如果说用needn't,只能是当need是情态动词的时候才可以。

如果是needn't那么这个句子的谓语就没了，所以不是needn't
这句话中的need做的是实意动词，而并非情态动词

need 有两种用法既做实义动词又做情态动词，
实义动词时有人称和数的变化，如：I don't need any help（help在这里是名词）don't need + to do sth是正确的，是跟动词时。
情态动词时是needn't
