1、Unit 7 International Charities 第3课时grammar八年级英语下册同步精品讲义（牛津译林版）知识精讲一、基本概念主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。 例如：many people speak English. 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。巧记为：被动、被动、主被动。例如：English is spoken by many people.主语English是动词speak的承受者。 例如：He opened the door.他开了门。（主动句） The

2、door was opened.门被开了。（被动句） 二、基本分类被动语态的构成 被动语态由“be及物动词的过去分词”构成。不及物动词本身没有被动语态。 及物动词-本身意义不完整，后必须带宾语，有些还可以带双宾。不及物动词-本身意义完整，不需要带宾语，如带宾语必须通过介词。人称、数和时态的变化是通过be的变化表现出来的。现以eat为例说明被动语态在各种时态中的构成。 一般现在时：amisareeaten 一般过去时：waswereeaten 一般将来时：will beeaten 现在完成时：havehas beeneaten三、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

3、。 (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 made by them in the factory. 四、含有情态动词的被动语态 含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成，原来

4、带to的情态动词变成被动语态后“to”仍要保留。 We can repair this watch in two days. -This watch can be repaired in two days.
