表示谓语与主语之间的关系的动词形式叫做语态，分为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。
主动语态变被动语态主: I learn English. 被:Englishis learnedmeby歌诀是： 被动语态be字变，过去分词跟后面。 be + p.p表被动，时态就要看主动。了解被动语态1.被动语态的构成：be+p.p(动词过去分词)2、形式:
1） 一般现在时的被动语态：am/is/are+P.P 男孩玩帽子。The boy plays the hat.The hat is played by the boy.
一般过去时的被动语态：
was/were+P.PYao Ming played basketball
yesterday.Basketball was played by Yao Ming yesterday.姚明昨天打篮球。3)现在进行时的被动语态：
现在进行时： am/is/ are + v.-ing
+ 被动语态： be + p.p

现在进行时的被动语态：am/ is/ are + being + p.p
Tom’s father is hitting him.He is being hit by his father.Tom 的爸爸正在打他。 Well done!4)现在完成时的被动语态：
现在完成时： have/ has + 动词过去分词

情态动词 + 动词原形
+被动语态： be + p.p
－－－－－－－－－－－－－－－－－－－－－－－－－－
含有情态动词的被动语态：情态动词 + be + p.pWe must clean the classroom
every day.The classroom must be
cleaned by us every day.我们必须每天打扫教室。 被动语态的使用：
一、行为主体不明确，不必说出或者无法说出动作的执行者时。例如：
Football is played all over the world．
二、不易找到或根本就不可能找到动作的执行者时。例如：
My bike was stolen．我的自行车被盗了。 swf三.表示客观的说明常用“It is + 过去分词.”句型
比较常见的有　It is reported that…据报道　It is said that…据说　It is believed that…大家相信　It is suggested that…有人建议
据说S.H.E下周会来我们学校。
It is said that S.H.E will come to our school
next week.
大家相信她们会来。 　
It is believed that they will come.
Pay attention: 他给了我一个足球. He gave me a football.I was given a football by him.A football was given to me by him.1.如遇双宾语，最好变间宾（人），如若变直宾（物），间宾前加to或for （pass,lend,buy,write,bring,show,tell…）
2.这些动词真奇怪，主动句中to 离开，被动句中to回 来。
（feel,listen to,hear,let,have,make,look at,see,watch…)老师让Lucy擦黑板。The teacher made Lucy
clean the blackboard.Lucy was made to clean
the blackboard by the teacher.3.注意：含动词词组的被动语态，须将其看作一个整体，不可把它们分隔开来。He takes good care of the baby.The baby is taken good care of
by him.4. 用主动形式表示被动意义的常见情况： （1）一些由及物动词转化而来的不及物 动词加well, easily等副词，如：clean, read, sell, wash, write, cook, cut等。e.g. 1.This shirt _________ ( clean ) easily.
