@瞿庞5715：needn't 和don't need to有什么区别? -
盖忠18541826214…… 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?
