中考英语被动语态课件(共46张PPT)

Passive voice 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。 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---stopped 2.不规则动词的过去分词： am is are been have has had do done write written go gone His brother washes bowls every day. 主 谓 宾(受动者) Bowls are washed by his brother every day. 改为被动语态 They play football on Sunday.
