答案是 treated !此题考察分词作状语;请看:
分词作状语的形式:
done 被做(平时的状态) 举例:被遗弃在角落里,那件衣服看起来很久了.
翻译:Deserted in the corner,the coat looks old.
being done 正在被做(两动词同时发生) 举例:被仆人们奉承着,她愉悦地站在镜子前看着自己.
翻译:Being flattered by the servants,she's standing in front of the mirror,looking at herself delightedly.
你的这个例子属于上面那种情况!“被对待”和“脾气变坏”都是平时的状态!而being done是想强调分词与谓语动词同时发生!而且要说英文使用中出现概率来看,前者远远比后者用得多!
一着急,"仆人"那单词打错了.不好意思.
