英语动词有两种语态：主动语态和被动语态。
1.当我们不知道谁是动作的执行者，
2.或者只需强调动作的承受者时，要用被动语态。
被动语态结构：
be +(及物动词的) 过去分词 + (by …)

被动语态：

V(被动结构)+
by O（宾语）

补充：被动语态中的特殊情况
1.不及物动词带介词和介词宾语时，在变为被动语态时，仍然要带上介词。
The students listen to the teacher carefully in class.
------The teacher is listened to carefully by
the students in class.
They look after the new students in the school.
____ The new students are looked after by them
in the school.

2.当动词带有复合宾语(有宾补), 并且宾补是省去“to”的动词不定式时，在被动语态中应加上“to”
They make us do all the work.
___We are made to do all the work by them.
We often hear her sing songs.
__She is often heard to sing songs by us.
I saw him walk to school.
__He was seen to walk to school by me.
这些动词真奇怪，主动句中to 离开，被动句中to回 来。（ let ，have ，make，feel，see ,watch, hear,notice…)
3.当动词带双宾语时(一个宾语是指人，一个是指物)，将其中指人的宾语提前作被动句的主语时，另一个宾语按顺序照抄下来；如是将指物的宾语提前作被动句的主语，在被动句中则指人宾语前应加“to”或“for” 。常见加to的动词有give，send, teach，write, show, pass, ask, tell…常见加for的动词有make, draw, buy…

__1 I am given a flower by him everyday.
__2 A flower is given to me by him everyday.
