【语法解析】
现在完成时的被动语态
一、基本结构：
have/has been +及物动词过去分词
二.现在完成时的被动语态的形式：
(1)肯定式：主语+ have/has+ been+及物动词的过去分词+其他。
The car has been repaired. 这辆汽车已经被修理过了。
(2)否定式：主语+ have/has+ not+ been+及物动词的过去分词+其他。
The house hasn’t been cleaned for a long time. 这所房子很久没有打扫了。
(3)一般疑问式：Have/Has+主语+been+及物动词的过去分词+其他
Has my letter been received 你收到我的信了吗？
(4)特殊疑问式：特殊疑问词+have/has+主语+been+及物动词的过去分词+其他 How long has the car been used 这辆汽车用了多长时间了？
三、主要用法：
1. 表示发生在过去的动作对现在产生的影响或结果，这个动作是被动的。当动词为短暂性动词的时候，可与already或yet连用，但不能与for或since引导的表示一段时间的状语连用。
This novel has been translated into several languages.
2. 还可以表示在过去发生的，已知延续到现在的并可能持续延续下去的被动动作或状态。常与for或since引导的时间状语连用，或用于“How long…？”句型中。
The machine has been used for 3 years.
3. 用在时间或条件状语从句中，表示将来某时已完成的动作，即用现在完成时态的被动语态代替将来完成时的被动语态。
You can go home as soon as your homework has been finished.
四、注意：
1）现在完成时的被动语态的两个助动词：have/has和been 缺一不可。
2）注意与一般过去时被动语态的区别。一般过去时的被动语态表示一个被动的动作发生在过去，其结果对现在没有影响；而现在完成时的被动语态的动作或状态尽管发生在过去，但侧重说明该动作或状态对想在造成的影响或结果。 The machine has been repaired.
(说明动作发生在过去，对现在有影响，“修好了”)
The machine was repaired yesterday. (只说明动作发生在昨天)
3）不可与确定的表示过去或将来的时间状语连用（如yesterday, three days ago, in 1970,in 2050等），但可与不确定的时间状语连用（如 already，yet，just，often，recently，in the past few years等）
They have been punished recently.
4）有些动词像finish，buy，start，begin，return，join，marry，open，die等，表示的动作很短暂，我们称之为短暂性动词或非延续性动词。它们构成的现在完成时的被动语态不能够与for构成的短语，since构成的短语或引导的句子连用，也不能用于How long… 句型中。
