被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。一般现在时：am／is／are＋taught一般过去时：was／were＋taught一般将来时：will／shall be＋taught现在进行时：am／is／are being＋taught过去进行时：have／has been＋taught现在完成时：have／has been＋taught歌诀是：被动语态be字变，过去分词跟后面。三、被动语态的用法(1)不知道或没有必要说明动作的执行者是谁。例如：Some new computers were stolen last night.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)This book was published in 1981.这本书出版于1981年。(2)强调动作的承受者，而不强调动作的执行者。例如：the window was broken by Mike.窗户是迈克打破的。This book was written by him.这本书是他写的。Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证。歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。四、主动语态变被动语态的方法(1)把主动语态的宾语变为被动语态的主语。(2)把谓语变成被动结构(be＋过去分词)(根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。(3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：All the people laughed at him.He was laughed at by all people.They make the bikes in the factory.The bikes are madeby themin the factory
