Question

needn't do和don't need to do有什么区别？

Answer 1

是这样的，needn't do 和 don't need to do 两者有些差别。 \x0d\x0a就像needn't have done 和 didn't need to do 一样。 \x0d\x0a从用法上，前者是情态动词，后者是实义动词。 \x0d\x0a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”。 \x0d\x0a如：You needn't do the housework.(说话时你已经做了家务) \x0d\x0aYou don't need to do the housework.(说话时你尚未做家务
