had done
一、语态的概念英语中动词有主动语态(Active Voice)和被动语态(Passive Voice)之分。如果主语是动作或状态的发出者，动词就用主动语态；如果主语是动作或状态的承受者，动词就用被动语态。被动语态的基本结构是：“助动词be/get＋及物动词的过去分词”。上面语法感知中句6中的had done和句7中的had forgotten是过去完成时的主动语态；句1,2,5中的had been persuaded，had been promised，had been occupied是过去完成时的被动语态。
语法精析
二、过去完成时的被动语态的概念过去完成时的被动语态是过去完成时态和被动语态的叠合。表示过去某一时间以前已经完成的动作，常与by，before等引导的时间状语连用，其构成形式为“had＋been＋过去分词”。三、过去完成时的被动语态有以下三种形式1.过去完成时的被动语态的肯定式为：主语＋had been done＋其他成分。如：The task had been finished before 12：00 yesterday.2.过去完成时的被动语态的否定式为：主语＋had not been done＋其他成分。如：The task hadn’t been finished before 12：00 yesterday.
3.过去完成时的被动语态的疑问句式(1)过去完成时的被动语态的一般疑问句需将had提到主语的前面，即had＋主语＋been done＋其他成分。如：Had the task been finished before 12：00 yesterday?(2)过去完成时的被动语态的特殊疑问句为：疑问词＋had＋主语＋been done＋其他成分。如：What time had the task been finished yesterday?
四、过去完成时的被动语态常用于以下情况1.表示过去某一时间以前已经完成的动作，常与by，before等引导的时间状语连用。(1)By the time he got to the school，the first period had been finished.当他到达学校时，第一节课已经结束了。(2)The classroom hadn’t been cleaned before the teacher came.老师来之前，教室还没有打扫过。(3)How many buildings had been destroyed when the hurricane ended?飓风结束时摧毁了多少建筑物？(4)Had the new plan been discussed before the meeting?这个新计划在开会前讨论过吗？
2.在 told，said，knew，heard，thought等动词之后的宾语从句中，若表示过去某一被动动作时，用过去完成时。(1)They said the production costs of their company had been reduced.他们说公司的生产成本已经降低了。(2)The boy was reminded that his homework had not been handed in.这个男孩被提醒还没有交家庭作业。(3)The media reported more than 1,000 people had been killed in the earthquake.媒体报道有1 000多人在地震中丧生。
3.根据语意可以判断出两个过去的动作发生先后的被动语态，用过去完成时。(1)As the assignment had been done，he went on to search the Internet.因为任务已经完成了，他继续上网。(2)He did what he had been told to.他是按要求做的。
五、过去完成时与现在完成时的被动语态的用法区别现在完成时的被动语态表示相对于现在来说已被完成的动作，过去完成时的被动语态表示相对于过去某一时刻来说已被完成的动作。如：This polluted river has been cleaned.这条被污染了的河流已被净化。析：该句表示到现在为止这条河流已被净化。如：He said this book had been translated into Japanese.他说这本书已被译成日语。析：该句表示到他说话时所体现的时间为止这本书已被译成日语。
