初中英语语法复习（9） 被 动 语 态
英语的语态分主动语态和被动语态两种。主动语态的主语是动作的执行者；被动语态的主语是动作的承受者。
eg. We use a knife for cutting (主动句).
A knife is used for cutting (被动句)。
一、构成：be + 过去分词
eg. 1)The work is finished by him.
2)Chinese is spoken by people in China.
二、被动语态的时态
1.一般现在时：am/ is/ are + 过去分词
eg. English is spoken by Englishmen.
2.一般过去时：was/ were + 过去分词
eg. The machines were made in China.
3.一般将来时:will/shall/be going to be+过去分词
eg. A sports meeting will be held in our school next week.
4.现在完成时：have/ has been + 过去分词
eg. The work has been done by them.
5.现在进行时：am/ is/ are being + 过去分词。
eg. A new school is being built in our village.
6.过去进行时：was/ were being + 过去分词
eg. My TV set was being mended at that time.
综上所述：被动语态的时态只涉及be动词的变化（即：be动词的各种时态）
另外注意以下几点：
1.含情态动词的被动语态：
can / may / must / should + be + 过去分词
eg. He may be sent away from school.
2.带动词不定式的被动语态
eg. My bike needs to be mended.
3.在使用被动语态时，如需要指出动作执行者时，应用“by + 动作的执行者(宾格)”
eg. He was called Mike by us
4.不及物动词无被动语态（take place/ happen ; last ; rise ; sink ; fall等）
eg. The accident was happened two days ago (改错) _________
5.当宾语补足语是省to不定式时，在改作被动语态之后，应将省去的to还原。
eg.The boss made the workers work 12 ho...
