be needed被动结构。need doing和need to be done是相同的,都是主动表被动。指主语是物时的用法。仔细看下面例句哦!Two desks are needed in my room.我房间需要两张课桌。
The desks need cleaning/to be cleaned.桌子需要清干净。
The desks need cleaning/to be cleaned.桌子需要清干净。

作主语时,后面动词用不定式to do。
You need to wear warm clothes.
Your shoes need washing.
=Your shoes need to be washed.
作主语时,后面动词用不定式to do。
