3、被动语态被动语态的用法: 不知动作执行者时,常用被动语态.eg. My bike was stolen yesterday. This car is made in American.2. 不必要说出动作执行者时,常用.eg. Rome was not built in a day.3. 为了突出强调动作的承受者时,常用被动语态.eg. Thousands of beaches are polluted (污染).The passive voice.被动语态主动语态变为被动语态的步骤:把原主动句中的宾语转换为被动语态的主语.2.把动词改为被动形式,即 “be + 过去分词” . 注意 be动词
