语态：表示主语和谓语动词之间的关系。 英语有两种语态，即主动语态和被动语态。 主动语态：表示主语是动作的执行者。 被动语态：表示主语是动作的承受者。 如： Many students study English.(主动语态) English is studied by many students. (被动语态)
助动词be有人称、数的变化,其变化规 则与be作为连系动词时一样。 如：The desk is made of wood. The desks are made of wood. He is asked a question by the teacher.
1.Many students study English. English is studied by many students.
2.They make shoes in that factory. Shoes are made by themin that factory.
3.The teacher often asks him questions.
He is asked questions by the teacher.
1.把主动语态的宾语变为被动语态的主语。 2.把主动语态的谓语变为被动语态的谓语。 3.把主动语态的主语变为被动语态的by 短语。（① by短语可以省。② by短语 后跟代词的宾格。）
主变被解题步骤 1. 找宾语 ----即动作的承受者 2. 判断宾语的单复数 ----即be动词的单复数. 3. 判断动词的时态 ----即be动词的时态. 4. 修改谓语的形式 ----即原句动词改为过去分词 5. 修改原句的主语 ----即by+ 宾语（原主语）. They make shoes in that factory. Shoes are made by them.
主变宾,宾变主, 谓动be done 时不变,人称、数、格随着变

1.带双宾语句子的被动语态.（指物的宾语叫直接宾语， 指人的宾语叫间接宾语） 常见的接双宾语的动词有: to: pass, give, teach, show, bring, hand for: make, buy, draw, sing, get, 以“人”当主语时，变法和
一般的变法一样； 以“物”当主语时，在保留的间接宾语前必须加to或 for. 如：1.He gave me a book. －I was given a book by him. （以I做主语） －A book was given to me by Tom. （以物book作主语） 2.He teaches us English. －We are taught English by him. （以人当主语） －English is taught to us by him. （以物作主语）

不及物动词没有宾语，因此没有被动语态。 但有的不及物动词后面加上介词及其他一些 词类构成短语动词之后，其作用相当于及物 动词，可以接宾语，因而也可以变为被动语 态。在变成被动语态时，不能去掉构成短语 动词的介词或副词.
They take good care of my child. My child is taken good care of . I turned off the radio. The radio was turned off (by me)
动词短语的被动语态 take care of －be taken care of cut down －be cut down laugh at －be laughed at look after－be looked after 下列这些短语本身即是被动语态的 形式，不需再加－by be covered with …用…覆盖着 be interested in …对…感兴趣 be surprised at …对…感到惊奇 be made of （from）用…制造的
即feel , hear , listen , have , make , let , look , watch , see , notice ，这些词在主动 句中，其后的动词不定式不加to，但变被 动句时必须加to.
1.I saw him play basketball last Sunday. He was seen to play basketball last Sunday.
2.We heard them sing in the classroom. They was heard to sing in the classroom.
