3、变，过去分词跟后面,找一找规律,(一)被动语态基本用法: 当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由助动词be+过去分词构成，时态通过be表现出来。,be + 过去分词,(二)被动语态的基本结构:,有各种时态的变化,1.规则动词的过去分词：,1)一般情况在动词原形后加-ed,watch-watched,2)以不发音e结尾的加-d,practice-practiced,3)以辅音加y结尾的，去y变i加-ed,study-studied,4)以重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加-ed,stop-stopp

6、ave/ has+ been + PP,5. Flowers _ every day. A. has been watered B. should be watered C. should water,含有情态动词的被动语态： 情态动词 + be + PP,(四)主动语态变被动语态: (1)把原来的宾语提到前面作被动语态的主语; (2)把谓语动词变成被动结构(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。如： They make the bikes in the fac
