1.hadbeendone---Thetaskhadbeendonebylastmonth.

　　2.have/hasbeendone---Thehousehasbeenpainted.

　　3.is/arebeingdone---Thebuildingisbeingtorndownnow.

　　我问的是非谓语动词形式的用法

　　1.Tiedbythepolice,hefeltveryuncomfortable.过去分词表被动，表完成。其逻辑主语是主句主语he,因he与tie构成了被动关系，所以用过分。例：Beatenbyhisfather,helefthome.2.Havingfinishedmyhomework,Ieventuallyhadtimeforamovie.---havingdone的逻辑主语是主句主语I，I与finish构成了主动关系，且finish这个动作发生在谓语动词之前，所以用havingdone.havingdone表主动，且表示的动作在谓语之前发生。例：Havingwashedherclothes,shecontinuedtodootherhousework.3.beingdone是一种形式为主动而意表被动的形式，它表示的动作与谓语同时发生。例：Beingexaminedbythevet,thedogstruggledtogetup.Beingpaintednow,thegategaveoffaterriblesmell.
