各种时态的被动语态是如何构成的,被动语态的构成

网友回答

被动语态的构成是助动词be加上过去分词，常常这样表示：be + V-ed， 那么各种时态的被动语态怎么表现的呢？
　　一般时态中
　　1、 一般现在时 am/is/are + V-ed
　　2、一般过去时 was/were +V-ed
　　3、一般将来时 will +be+V-ed
　　进行时态中
　　1、现在进行时 am/is/are + being +V-ed
　　2、过去进行时 was/were +being +V-ed
　　3、将来进行时 would +be +V-ed
　　完成时态中
　　1、现在完成时 has/have + been + V-ed
　　2、过去完成时 had + been +V-ed
　　3、将来完成时 will +have + been +V-ed
　　这些是最基本的几种时态的被动语态构成，只要理解了被动语态最基本的构成，任何时态都可以应对。
