当主语为动作的执行者时, 谓语的形式为主动语态; 当主语为动作的承受者时, 谓语要用被动语态。
e.g. Many peple speak English. （主动语态, 句子的主语many peple是 动作speak的执行者） English is spken by many peple. （被动语态, 句子的主语English是动作 speak的承受者）
被动语态主要用于以下几种情况：1. 强调动作的承受者。如：The English-Chinese dictinary is used by mst students.2. 不知道动作的执行者。如：The bk was published (出版) last year.3. 没有必要提及执行者。如：Such things are nt dne twice.
4. 被动语态的使用往往受上下文和语境支配。在一个句子中有时为了避免中途变更主语而不得不使用被动语态。如： Jack played Mike at ping-png and (Jack) was easily beaten.5. 有些动词习惯上常用被动语态。如： Tim is thught t be the best student in ur class.
与主动语态一样，被动语态也有时态、人称和数的变化, 其变化规则与be作为连系动词时完全一样。
一般现在时被动语态的构成：be (am / is / are) +及物动词的_____分词 The bk is written in Chinese.The bk isn’t written in Chinese.
一般疑问句：—Is the bk written in Chinese?—Yes, it is. / N, it isn’t.特殊疑问句：What language is the bk written in?
如何将主动句(含“主+谓+宾”句型的句子)变为被动句主动句：  Jhn       helps              me.被动句：   I         am helped        by Jhn.这一基本句型变为被动句时，先将主动句中的宾语变成被动句中的主语(宾语如为人称代词，须将宾格变为_______)
主动句：  Jhn       helps              me.被动句：   I         am helped        by Jhn.然后根据这个主语选用相应的助动词be (am / is /are)，然后将主动句中的谓语动词变成它的过去分词形式，再将主动句中的主语置于介词by 之后(如为人称代词，须将主格变为宾格)，最后将句中的其他成分加上即可。

点拨：将主动语态变为被动语态时，应先确定句子的谓语动词，并找出句子的宾语。然后，将句子的宾语变成被动句的主语，将谓语动词变成be + v.-ed形式。
2. This shp uses the best materials t make dresses. ________________________________ ________________________________
1) 主动句的谓语动词为use, 宾语是the best materials。2) 将the best materials作被动句的主语, 谓语动词改为are used的形式。
