語態是動詞的一種形式，它用來表示句中主語同謂語動詞之間的關係。
英語有兩種語態， 主動語態和被動語態， 主動語態表示主語是謂語動詞動作的執行者，被動語態表示主語是謂語動詞動作的承受者。例如：
I have repaired the radio.
我修好了收音機。
The radio has been repaired.
收音機被修好了。
The students cleaned the classroom.
學生們打掃了教室。
The classroom was cleaned by the students.
教室被學生們打掃了。
被動語態的構成：
be + 過去分詞
A building was damaged by the storm.
暴風雨毀壞了一座建築物。
Our plate was made in China.
我們的盤子是中國生產的。
My bike was stolen.
我的.自行車被盜了。
常用的被動語態的時態變化如下，以 ask 爲例：
一般 進行 完成
現在I am asked, I am being asked, I have been asked
過去I was asked,I was being asked,I had been asked
將來I shall be asked, I shall have been asked
過去將來I shall be asked
