1、Passivevoice,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,
