the room is quite neat,it doesn't need cleaning
问题描述:
the room is quite neat,it doesn't need cleaning
怎么不说it needn't cleaning
答
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 .
