单元语法发散思维
一般过去时被动语态：
构成：主语 + was ( were ) + 及物动词的过去分词。
陈述句 ( Statements ) : The letter was written a week ago . 这封信是一星期前写的。
疑问句 ( Questions ) : Was the letter written a week ago ? / When was the letter written ? 例句：
The museum was built two years ago . 这个博物馆是两年前建成的。
Was the thief caught by a policeman ? 这个小偷是被警察抓住的吗 ?
Where were the children found ? 孩子们是在哪被发现的 ?
When was the watch bought ? 这块手表是什么时候买的 ?
The thermos were used for keeping water hot . 这些暖水瓶是用于保存热水的。
主动语态变被动语态的四个步骤：
①把主动语态句子中的宾语变成被动语态句子的主动。
②把主动语态句子中的谓语变成被动语态：be + 动词的过去分词。注意被动语态中 be 的时态与主动语态句子中的谓语动词的时态相同。
③把主动语态中的主语变为 by 的宾语 ( 如为代词，主格形式变成宾语形式 ) 。如果动作执行者不需要强调或说明，by 短语可以省略。
Everybody likes Tom . 大家都喜欢汤姆。
Tom is liked by everybody . 汤姆被大家喜欢。
He wrote a letter . 他写了一封信。
A letter was written by him . 这信是他写的。
They are building a road . 他们正在修一条路。
A rood is being built ( by them ) . 那条路在修建中。
含有两个宾语的主动结构变为被动结构
主语结构中若有两上宾语 ( 直接宾语和间接宾语 ) ，通常将表示人的间接宾语变为被动态主语，而直接宾语 ( 表示物的 ) 作为保留宾语而不动。有时也可将直接宾语变为被动语态主语，间接宾语作为保留宾语而不动，但其前通常要加介词 to 或 for。如：
He gave me some books . 他给了我一些书。 ( 主动语态 )
I was given some books . ( 间接宾语作主语 ) ( 较常见 )
Some books were given to me . ( 直接宾语作主语 )
Father bought me a pen . 父亲给我买了支钢笔。
I was bought a pen . ( 间接宾语作主语 )
A pen was bought for me . ( 直接宾语作主语 )
含有复合宾语的主动结构变为被动结构
主动结构中如有复合宾语 ( 即：宾语 + 宾语补足语 ) ，变为被动语态时，只将复合宾语中的逻辑主语 ( 即宾语 ) 变成主语，其余部分不动。如：
We found him working in the fields . 我们发现他在田里工作。
He was found working in the fields . 他被发现在田里工作。
They named the baby Mary . 他们给这个小婴儿取名玛丽。
We elected Xiao Zhang our team leader . 我们选小张当队长。
