被动语态答案

讲解篇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、不同时态的被动语态：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.

He may be sent away from school.2.带动词不定式的被动语态: to be +过去分词 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.

(1)The accident was happened two days ago (改错) _ (2)Great changes _(发生 )in China over the past years.(3)The bread _ in this shop and it _ well(卖).5. 一些动词不定式在主动语态中省略to作宾语补足语，改成被动语态时，to必须还原。（feel,listen to,hear,let have,make,look at,see,watch)eg.(1)The boss made the workers work 12 hours.The workers were made _12 hours.eg.(2)The students was made _ the questions by the teacher.A. answer B. to answer C. answering D. answeredeg.(3)Yesterday he _(被看到募集)money for the charities.eg.(4)An educational CD-ROM _ (给我买)by Lily last week.eg.(5)Lily _(被听到唱歌) in the room at that moment.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.
