初三英语被动语态讲解与精练

1、初三英语被动语态讲解与精练初中英语被动语态一、语态概述英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：Many people speak Chinese.谓语：speak的动作是由主语many people来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people.主语English是动词speak的承受者。二、被动语态的构成被动语态由“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speak为例说明被动语态在各

9、ot;句型还有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有人建议六、动词的主动形式表示被动之意（1）以主动形式表示被动之意的动词多为连系动词，如：look, feel, smell等。The flower smells sweet.这花闻起来很香。The watch looks good.这表看起来很好。This book sells well.这本书畅销。（2）下列动词没有被动式：happen，cost，take placeAn accident was happened

10、 yesterday.（×）昨天发生了一起事故。An accident happened yesterday.（ ）七、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
