考试常见语法动词语态

语态是动词的一种形式，它用来表示句中主语同谓语动词之间的关系。

英语有两种语态， 主动语态和被动语态， 主动语态表示主语是谓语动词动作的执行者，被动语态表示主语是谓语动词动作的承受者。例如：

I have repaired the radio.

我修好了收音机。

The radio has been repaired.

收音机被修好了。

The students cleaned the classroom.

学生们打扫了教室。

The classroom was cleaned by the students.

教室被学生们打扫了。

被动语态的构成：

be + 过去分词

A building was damaged by the storm.

暴风雨毁坏了一座建筑物。

Our plate was made in China.

我们的盘子是中国生产的。

My bike was stolen.

我的.自行车被盗了。

常用的被动语态的时态变化如下，以 ask 为例：

一般 进行 完成

现在I am asked, I am being asked, I have been asked

过去I was asked,I was being asked,I had been asked

将来I shall be asked, I shall have been asked

过去将来I shall be asked
