桂妮15779883218…… didn't need to do里need是普通动词,就是need本来的意思,(过去)没必要/不需要做某事 need not have done 里need是情态动词,意思是本来无必要做某事(却做了),本不该做某事 例如:He did not need to come early, so he came late.他不需要早来,所以他来得晚.He needn't have come early, but he did and waited one hour.他不需要早来却早来了,还等了一个小时.
@汲戚3101：needn't 和don't need to有什么区别? -
桂妮15779883218…… 是这样的,needn't do 和 don't need to do 两者有些差别. 就像needn't have done 和 didn't need to do 一样. 从用法上,前者是情态动词,后者是实义动词. 从意义上,前者暗示已经做了,有“本不需要”的意思,后者暗示还没有做,就是纯粹地“不需要”. 如:You needn't do the housework.(说话时你已经做了家务) You don't need to do the housework.(说话时你尚未做家务 这样可以么?

@汲戚3101：needn't have done和didn't need to do 有什么不同 -
桂妮15779883218…… need+to do,needn't+do sth ,至于didn't和have一个是过去式,一个是现在完成时,过去式+do,完成式+done
@汲戚3101：don't need 和need not 怎么用?后面该加怎样的动词形式 -
桂妮15779883218…… 判断need做哪种动词,你可以看后面的动词形式. need做实意动词:need to do,否定在前面+don't或者doesn't need做情态动词:need do(动词原形),否定在后面+not 考试的时候可以根据后面的动词形式,即是动词原形还是不定式to do,来判断前面用don't或者doesn't还是not否定,也可以根据前面否定形式,来判断后面用to do还是动词原形
@汲戚3101：英语问题don't need to need't to not need to -
桂妮15779883218…… don't need to do 例如:you don't need to go with me. needn't后面不用加to的,如果写成needn't,那它就是情态动词,和should can……一样,没有写成should to的,因此也不写成needn't to not need 和don't need 是一样可以加的.
@汲戚3101：Don't need , needn't , don't need to , needn't to 有什么区别?急求!!! -

@汲戚3101：need to do sth,need do sth. needn`t do sth和don`t need有什么不同.
桂妮15779883218…… need可以作情态动词也可以作普通动词. 当它是情态动词的时候,肯定形式就是need do sth.否定形式是needn\'t do sth. 当它是普通动词时候,肯定形式是need to do sth.否定形式是don\'t need to do sth. 重要的是,need当情态动词时,一般不用于肯定句~ 且作为must提问的否定回答 must I do the homework no,you needn\'t.
