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。 一般过去时被动语态的几种句型: 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…) The news wasn’t published by the government. 3) 一般疑问句: Was/Were + 主语 + V-ed + (by…)? 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?
1. “不及物动词+介词 / 副词”构成的短语动词，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.
顺口溜：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 【运用】 Ⅰ. 单项选择
