1、中考语法精讲被动语态1我吃了一个苹果,那现在苹果怎样了?苹果被2苹果被我吃了。正如汉语中的被字句,英语中的“被字句”我们称之为被动语态。3英语中有两种语态:主动语态和被动语态。4一:英语的谓语动词有两种语态WespeakEnglish.主语谓语宾语主动语态主动语态表示主语是动作的执行者。谓语speak的动作是由主语we执行的,即主语是是谓语动词所表示动作的执行者。5两种语态Englishisspokenbymanypeople.主语谓语宾语被动语态主语English是谓语动词speak所表示的动作的承受者。被动语态表示主语是动作的承受者。6Wecleanourclassroomeveryday
