同学们，经过两次与被动语态的接触，对英语中被动语态的用法应该已经有了一定的了解。那么下面这道中考题你会做吗？
The window _____ ten minutes ago, and the room is bright now.
A. has been cleaned B. is cleaned C. was cleaned D. will be cleaned
该题中的四个选项分别为被动语态的四种时态形式。由句中“ten minutes ago”可知，这是谈论过去发生的事情，故用一般过去时的被动语态形式，C项正确。
被动语态的时态是通过助动词be的变化来表示的。各地中考试题经常考查的被动结构是：
1. am / is / are + 及物动词的过去分词（一般现在时）；
2. was / were + 及物动词的过去分词（一般过去时）；
3. will / shall + be + 及物动词的过去分词（一般将来时）；
4. have / has been + 及物动词的过去分词（现在完成时）；
另外，主动语态可以转换为被动语态，其方法步骤是：
1. 主动句的宾语变为被动句的主语。
2. 主动句的谓语动词变为被动形式，这里要注意助动词be的时态与主动句的时态保持一致，数与被动句的主语保持一致。
3. 主动句的主语变为被动语态中by的宾语（如为代词，主格要变为宾格）。
They have painted their new house. （改为被动语态）
Their new house _____ _____ _____ by them. 答案：has been painted）
【温馨提示】
1. 当主动句中的谓语是“四看（see，watch，look at，notice）”、“三使役（let，have，make）”、“两听（hear，listen to）”、“一感觉（feel）”时，其后作宾语补足语的动词不定式要省略to，但变为被动句时，不定式中的to 不能省略。例如：
The boss made him work twelve hours a day.
→ He was made to work twelve hours a day by the boss.
2. 把含有短语动词的主动语态变为被动语态时，要保持短语动词的完整性，不得使句子缺“胳膊”少“腿”。例如：
The workers put up a tall building in my hometown last year.
→ A tall building was put up in my hometown last year.
