The room is very dirty,is needs ( )clean正确形式填空

cleaning
need 后动名词主动式表被动
It needs cleaning= It needs to be cleaned

to be

needs cleaning或者needs to be cleaned都可以。
need,require,want他们后面直接加上动词现在分词，可以主动形式表示被动意义。

句意：房间太乱，需要整理。
房子本省不会自我整理，所以需要的是被动语态；
need，可用2种形式表示：1.直接加动名词表被动；
2.need to be done.
所填应为：


cleaning；
或者
to be cleaned。

The room is very dirty,is needs ( to)clean
