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 f wd. The desks are made f wd.He is asked a questin by the teacher.

如：1.He gave me a bk. －I was given a bk by him. （以I做主语） －A bk was given t me by Tm. （以物bk作主语） 2.He teaches us English. －We are taught English by him. （以人当主语） －English is taught t us by him. （以物作主语）
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: t: pass, give, teach, shw, bring, hand fr: 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t或fr.
keep, make 三类的动词常常有宾语补足 语，在被动语态中，宾语补足语位置不变。 We keep fd fresh in the fridge. 主 谓 宾 宾补 －Fd is kept fresh in the fridge. I saw him g int the ffice building. －He was seen t g int the ffice building.
2.含有宾语补足语的句子的被动语态
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 gd care f my child. My child is taken gd care f .I turned ff the radi. The radi was turned ff (by me)
3.含有短语的主动语态变被动语态
即feel , hear , listen , have , make , let , lk , watch , see , ntice ，这些词在主动句中，其后的动词不定式不加t，但变被动句时必须加t.
1.I saw him play basketball last Sunday.
t play basketball last Sunday.
2.We heard them sing in the classrm.
t sing in the classrm.
4.感官动词和使役动词的被动语态
（1）当主动结构中的宾语是反身代词和相互代词 时，不能改为被动语态。 We ften help each ther. 我们常常互相帮助。 （2）当谓语是表状态的及物动词时（如have , like , take place , belng t …） 如： I like these flwers. 我喜欢这些花。 I will have a meeting. 不说A meeting will be had. 应说A meeting will be held .
5.不能用于被动语态的几种情况
