Summary 一、被动语态 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 people speak English. （主动语态, 句子的主语many people是动作speak的执行者） English is spoken by many people. （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 dictionary is used by most students.2.不知道动作的执行者。如：The book was published (出版) last year.3.没有必要提及执行者。如：Such things are not done 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-pong and (Jack) was easily beaten.5.有些动词习惯上常用被动语态。如： Tim is thought to be the best student in our class.二、被动语态的构成 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 book is written in Chinese.The book isnt written in Chinese.一般疑问句：Is the book written in Chinese?Yes, it is. / No, it isnt.特殊疑问句：What language is the book written in?肯定式否定式疑问式一般现在时I am asked He/She is asked We/You/They are askedI am not askedHe/She is not askedWe/You/They are not asked Am I asked ?Is he/she asked ?Are we/you/they asked ?如何将主动句(含“主+谓+宾”句型的句子)变为被动句主动句： John helps me.被动句： Iam helped by John.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： John helps me.被动句： Iam helped by John.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。IV.
