1.“want + sth(her paintings) + done(displayed)”意思是“想要某事被做”,因?yàn)橘e語(yǔ)her paintings和賓補(bǔ)動(dòng)詞display之間為被動(dòng)關(guān)系,所以使用其過(guò)去分詞displayed做賓語(yǔ)補(bǔ)足語(yǔ).
2.want sth doing (sth)該結(jié)構(gòu)不存在,更不會(huì)表示什么被動(dòng).
俺知道樓主想說(shuō)的短語(yǔ)是sth want doing = sth want to be done,它才是用主動(dòng)形式表示被動(dòng)含義,此時(shí)want類似于need.
如：My hair wants cutting.= My hair wants/needs to be cut.
我的頭發(fā)需要修剪.
