被动语态(Passive Voice)表示句子的主语是动作的接受者或受影响者。被动语态的基本动词形式是be+v.-ed。通过改变be的时态，可以构成不同时态的被动语态。
一般过去时的被动语态，其构成为：was /were+及物动词的过去分词。
1. 肯定句: 主语 + was/were + v.-ed + (by…)
The news was published by the government.
2. 否定句: 主语 + was/were + not + v.-ed + (by…)
3. 一般疑问句: Was/Were + 主语 + v.-ed + (by…)
The news wasn’t published by the government.
Was the news published by the government
4. 特殊疑问句: 疑问词 + was/were + 主语 + v.-ed
+ (by…)
When was the news published by the government
一般过去时被动语态的几种句型
1. “不及物动词+介词/副词”构成的动词短语，变成被动句时，要把它们作为整体看待，介词或副词不可与其动词拆开或漏掉。如：
Our homework was handed in yesterday afternoon.
The house was fixed up by my father.
2. 含有双宾语的主动句变被动句时，可将主动句中的直接宾语或间接宾语变为被动句中的主语。如果把主动句中的直接宾语(指物)变为被动句中的主语，则需在间接宾语(指人)前加适当的介词to或for。如:
主动结构：
Danny gave me a ticket just now.
被动结构：
A ticket was given to me by Danny just now. (直接宾语作主语)
I was given a ticket by Danny just now.
(间接宾语作主语)
3. 有些动词常用其主动形式表示被动意义，如sell, wash, write等和表示感觉、知觉的系动词feel, sound, taste, smell等。如：
This kind of dress sells well.
The fish tastes very delicious.
4. 在主动句中, 使役动词(如make等)和感官动词 (如see, watch, notice, hear等)后面常接不带to的动词不定式作宾语补足语; 但在被动句中，这些词后面的动词不定式都需要带to。如：
The boss made us work for ten hours today.
→We were made to work for ten hours today
by the boss.
Mom heard Ben sing in the next room.
→Ben was heard to sing in the next room by
Mom.
感官动词
一感二听三让四看
主动句中to 离开，被动句中to回来
