一、被动语态1.英语动词有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
②我们都被那个故事感动哭了。We ___________ t tears by the stry.我们没有被那个故事感动哭。We _______________ t tears by the stry.你们被那个故事感动哭了吗?Were yu _______ t tears by the stry?
were nt mved
2.主动变被动解题步骤:
1. 找宾语 ——即动作的承受者
2. 判断宾语的单复数——即be动词的单复数
3. 判断动词的时态 ——即be动词的时态
4. 修改谓语的时态——即原句动词改为过去分词
5. 修改原句的主语——即by+ 主语 / 宾语
3.主动语态变被动之歌：被动语态强调宾，be后加上过去分。be要随着主语变，人称时态要弄准。行为对象作主语， 逻辑主语by来引。
