Past Perfect Passive过去完成时的被动语态
A. 主动语态：had + 过去分词
We had finished learning Bk1 till last week.
Bk1 had been finished learning (by us ) tilllast week.
B. 过去完成时的被动语态的常见用法：
（1）用在 tld, said, knew, thught 等动词后的宾语从句中，表示宾语从句中的动作已被做完。例：
他说那些书已经卖完了。 He said that the bks had already been sld ut. 那个男孩被提醒他的家庭作业还没交。 The by was reminded that his hmewrk had nt been handed in.
到去年年底，已经建成了120座桥。By the end f last year, 120 bridges had been built.
（2）当 befre, when, by the time, until 等引导的时间状语从句的谓语是一般过去时，以及 by, befre 后面接过去的时间时，主句的动作发生在从句的动作或过去的时间之前且表示被动时，要用过去完成时的被动语态。例：
（3）在 It was the first /secnd / … time that… 从句中，主语是动作的承受者时，要用过去完成时的被动语态。例：
这是他的自行车第二次被偷。 It was the secnd time that his bike had been stlen.这幅画是第一次向公众展出。 It was the first time that the painting had been displayed t the public.
（4）在虚拟语气中，条件句表示与过去的事实相反，且主语是动作的承受者时，要用过去完成时的被动语态。例：
如果早一点邀请我，我就和你一起去了。If I had been invited earlier, I wuld have gne with yu.

1.A rescue wrker risked his life saving tw turists wh 　　　 　. (trap) in the muntains fr tw days.(2018年北京卷,单项填空改编) 
had been
1.had been trapped　考查动词时态和语态。“wh 　　 　　 in the muntains fr tw days”是定语从句,修饰tw turists,tw turists和trap之间是被动关系,且“游客被困两天”应该发生在营救人员救了他们之前,即“过去的过去”。故用过去完成时的被动语态形式。 
2.Jnes gt the idea after he had talked with an elderly lady wh 　　 　　(cheat) f her mney.(2020年天津卷,完形填空改编) 
had been cheated
2.had been cheated　考查动词时态和语态。lady与动词cheat之间为被动关系,且这一动作发生在主句的谓语动词所表示的动作之前。故用过去完成时的被动语态形式。
