the room is quite neat,it doesn't need cleaning怎么不说it needn't cleaning

问题描述:

the room is quite neat,it doesn't need cleaning
怎么不说it needn't cleaning

你好!很高兴为您解答!
因为need在这里是属于实义动词,所以否定用doesn`t need.当need用做情态动词时,其否定才直接在后面加not

希望可以帮到您,祝您成功!

这个need必须是实意动词用法啊,后面是动名词,像你那样当成情态动词来用的话,后面要跟动词原形啊

这句中的need是实意动词,是“需要”的意思,否定形式是助动词do+not+need原型.
need后接宾语.如下说明:
need cleaning(动名词)=need to be cleaned(不定式充当名词形式)
need a book(需要一本书).
need做情态动词时,后面加的是动词原型,此时的need 否定形式才是 needn't .
