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 hours.
→The workers were made to work 12 hours.
6.注意短语动词的完整性(即:主动句的谓语动词若由v + prep / adv构成,变被动语态时,不能将这些介词、副词遗漏。
eg. We must take care of the baby.
→The baby must be taken care of.
