贺仁栋回答:
1被动语态的构成
被动语态的基本结构是“助动词be+过去分词”.被动语态的谓语动词有各种时态变化,以动词take为例,将被动语态常见时态的动词形式列表如下:
一般现在时
现在进行时
现在完成时
一般将来时
am/is/are
taken
am/is/are
beingtaken
have/hasbeen
taken
will/shallbe
taken
一般过去时
过去进行时
过去完成时
过去将来时
was/were
taken
was/were
beingtaken
hadbeen
taken
would/should
betaken
从上表中可以看出,被动语态的各种时态变化都是通过助动词“be”的各种时态来表示的,因此只要知道“be”的时态形式,也就掌握了被动语态构成
