余盛宝2956need do sth 还是need to do sth ?
伏宏毅13725718339 ______ 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.

余盛宝2956为什么need有些时候否定形式do(es) not need ,而有时候为needn't?什么情况下用哪个呢?是否有使用诀窍? -
伏宏毅13725718339 ______ 诀窍就是:判断need在句中是作为情态动词还是实意动词用的: need作为实义动词时和普通动词一样,否定用don't need; need作为情态动词时比较特殊,用needn't形式.(与其他情态动词“can”,“may”,“must”的用法基本相同.) 所以关键就是判断是作为情态动词还是实意动词用. 若need后边加的是动词原形,则为情态动词;若加的是to do,则为实意动词. 所以关键在于根据need后接的是什么,判断need在句中是实意动词还是情态动词,然后就用don't need或者 needn't. 希望对你有所帮助!

伏宏毅13725718339 ______ 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
